METHODS AND APPARATUS FOR INDICATING TRANSMISSION PRIORITY BASED ON A CONFIGURATION OF THE HYBRID AUTOMATIC REPEAT REQUEST
BACKGROUND OF THE INVENTION
Field [0001] Aspects of the present invention refer, in general, to wireless communication and, more particularly, to techniques and devices for indicating the transmission priority based on a hybrid automatic repeat request (HARQ) configuration.
Fundamentals [0002] Wireless communication systems are widely implemented to offer various telecommunications services, such as telephony, video, data, messages and transmissions. Typical wireless communication systems can employ multiple access technologies capable of supporting communication with multiple users, sharing available system resources (for example, bandwidth, transmission power and / or the like). Examples of such multiple access technologies include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA), multiple division access systems orthogonal frequency (OFDMA), multiple access systems by frequency division with single carrier (SCFDMA), multiple access systems by synchronous code division and time division (TD-SCDMA) and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of advances to the mobile standard of the Universal Telecommunications System

Furniture (UMTS) promulgated by the Third Generation Partnership Project (3GPP).
[0003] A wireless communication network can include a series of base stations (BSs) that can support communication for a number of user devices (UEs). A UE can communicate with a BS through the downlink and uplink. The downlink (or direct link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail in this document, a BS can be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit and receive point (TRP), a new BS radio ( NR), a Node B 5G and / or similar.
[0004] The multiple access technologies above have been adopted in various telecommunications standards to provide a common protocol that allows different wireless devices to communicate at a municipal, national, regional and even global level. The Novo Rádio (NR) technology, which can also be referred to as 5G, is a set of advances to the mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to offer better support for mobile broadband Internet, improving spectral efficiency, reducing costs, improving services, making use of new spectrum and better integrating with other open standards using orthogonal frequency division multiplexing ( OFDMA) with a cyclic prefix (CP) (CP-OFDM)) in the downlink (DL), using CP-OFDM and / or SC-FDM (for example, also known as OFDM diffused by discrete Fourier transform (DFT-s- OFDM) on the uplink (UL), as well as support for

3/75 beam formation, antenna technology with multiple inputs and outputs (MIMO) and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there is a need for advances in LTE and NR technologies.
[0005] Preferably, these advances should be applicable to other multiple access technologies and telecommunications standards that employ these technologies.

12/75 computer storage. Storage media can be any available media that can be accessed by a computer. As an example, and not as a limitation, these computer-readable media may include random access memory (RAM), read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), compact ROM (CD- ROM) or other optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the said types of computer-readable media or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

14/75 provide, for example, connectivity to or to a network (for example, a wide area network, such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered machine-type communication (MTC) UEs, which can include remote devices that can communicate with a base station, another remote device or some other entity. Machine-type communications (MTC) can refer to communication involving at least one remote device on at least one end of the communication and may include forms of data communication that involve one or more entities that do not necessarily need human interaction. MTC UEs may include UEs that are capable of MTC communications with MTC servers and / or other MTC devices over Public Land Mobile Networks (PLMN), for example. Examples of MTC devices include sensors, meters, location tags, monitors, drones, robots / robotic devices and / or the like. TCM UEs, as well as other types of UEs, can be implemented as NB-IoT (narrowband internet of things) devices.
[0039] It should be noted that, while aspects can be described here using terminology commonly associated with 3G and / or 4G wireless technologies, aspects of the present invention can be applied to communication systems based on other generations, such as 5G and subsequent, including NR technologies.
[0040] A figure 1 and a diagram what illustrates an network 100 on what can to be practiced the aspects gives gift invention. The net 100 Can be an LTE network or
Petition 870190061133, of 7/1/2019, p. 11/191
15/75 some other wireless network, such as a 5G or NR network. Wireless network 100 can include a series of BSs 110 (shown as BS 110a, BS 110b, BS 110c and BS HOd) and other network entities. A BS is an entity that communicates with user equipment (UEs) and can also be referred to as a base station, an NR, a BS, a Node B, a gNB, a 5GNB, an access point, a TRP and / or similar. Each BS 110 can provide communication coverage for a specific geographic area. In 3GPP, the term cell can refer to an area of a BS and / or a subsystem of BS that serves that coverage area, depending on the context in which the term is used.
[0041] A BS can provide communication coverage for a macrocell, a picocell, a femtocell and / or another type of cell. [0065] A macrocell can cover a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographical area and can allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (for example, a household) and can provide access restricted by UEs with a femtocell membership (for example, UEs in a closed group of subscribers (CSG)). A BS for a macrocell can be referred to as a macro-BS. A BS for a picocell can be referred to as a peak BS. A BS for a femtocell can be referred to as a BS femto or a domestic BS. In the example shown in figure 1, a BS 110a can be a macro BS for a macro cell 102a,
Petition 870190061133, of 7/1/2019, p. 11/20
16/75 a BS 110b can be a BS peak for a 102c picocell and a BS 110c can be a BS femto for a 102c femtocell. A BS can support one or more (for example, three) cells. The terms eNB, base station, BS NR, gNB, TRP, AP, node B, NB 5G and cell can be used interchangeably in this document.
[0042] In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some examples, the BSs can be interconnected to each other and / or to one or more other BSs or network nodes (not shown) on the access network 100 through different types of backhaul interfaces, such as a direct physical connection, a network virtual and / or similar, using any suitable transport network. Wireless network 100 may also include relay stations. A relay station is an entity that can receive a data transmission from an upstream station (for example, a BS or a UE) and send a data transmission to a downstream station (for example, a UE or a BS). The relay station can also be a UE that can relay to other UEs. In the example shown in figure 1, an HOd relay station can communicate with the BS 110a macro and UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, a relay base station, a relay and / or the like.
[0043] Wireless network 100 can be a heterogeneous network that includes BSs of different types, for example
Petition 870190061133, of 7/1/2019, p. 11/211
17/75 example, macro-BSs, pico-BSs, Femto-BSs, retransmission BSs and / or the like. These different types of BSs can have different levels of transmission power, different coverage areas and different impact on interference in the wireless network 100. For example, macroBSs can have a high level of transmission power (for example, 5 to 40 Watts), while pico-BSs, femto-BSs and retransmission BSs may have lower levels of transmit power (for example, 0.1 to 2 Watts).
[0044] A network controller 130 can couple with a set of BSs and can provide coordination and control for those BSs. The network controller 130 can communicate with the BSs via a backhaul. BSs can also communicate with each other, for example, directly or indirectly via wireless or wired backhaul.
[0045] UEs 120 (e.g. 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be fixed or mobile. A UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station or the like. A UE can be a cell phone (for example, a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a portable computer, a cordless phone, a station wireless local loop (WLL), a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or medical equipment, biometric sensors / devices, wearable devices (smart watches, smart clothes, glasses smart bracelets, smart bracelets, smart jewelry

18/75 (for example, a smart ring, smart bracelet, etc.), an entertainment device (for example, a music or video device or a satellite radio), a vehicle component or sensor, smart meters / sensors , industrially manufactured equipment, a global positioning device, or any other suitable device that is configured to communicate via a wired or wireless medium. Some UEs can be considered UEs of the advanced or advanced machine type communication (eMTC). MTC and eMTC UEs include, for example, robots, drones, remote devices, such as sensors, meters, monitors, location tags, and / or the like, that can communicate with a base station, another device (for example, remote device ), or some other entity. A wireless node can provide, for example, connectivity to or to a network (for example, a wide area network such as the Internet or a cellular network) through a wired or wireless communication link. Some UEs can be considered devices of the Internet of Things (loT). Some UEs can be considered as Equipment at the User Facility (CPE).
[0046] In figure 1, a solid line with double arrows indicates desired transmissions between a UE and a service BS, which is a BS designated to serve the UE in the downlink and / or uplink. A dotted line with double arrows indicates potentially interfering transmissions between an UE and a BS.
[0047] In general, any number of wireless networks can be deployed in a given geographic area.

Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface and / or the like. A frequency can also be referred to as a carrier, a frequency channel and / or the like. Each frequency can support a single RAT in a given geographic area, in order to avoid interference between wireless networks from different RATs. In some cases, RAT NR or 5G networks can be deployed.
[0048] In some examples, access to the air interface can be scheduled, in which a scheduling entity (for example, a base station) allocates resources for communication between some or all devices and equipment within its area or service cell of the scheduling entity. Within the present invention, as discussed later, the scheduling entity may be responsible for scheduling, assigning, reconfiguring and releasing resources for one or more subordinate entities. That is, for scheduled communication, subordinate entities use resources assigned by the scheduling entity.
[0049] Base stations are not the only entities that can function as a scheduling entity. That is, in some instances, a UE can function as a scheduling entity, scheduling resources for one or more subordinate entities (for example, one or more other UEs). In this example, the UE is functioning as a scheduling entity, and other UEs use the resources scheduled by the UE for communication without
Petition 870190061133, of 7/1/2019, p. 11/24
20/75 thread. A UE can function as a scheduling entity on a peer-to-peer (P2P) network, and / or on a mesh network. In an example of a mesh network, UEs can optionally communicate directly with each other, in addition to communicating with the scheduling entity.
[0050] Therefore, in a wireless communication network with scheduled access to time-frequency resources and with a cellular configuration, a P2P configuration and a mesh configuration, a scheduling entity and one or more subordinate entities can communicate using the scheduled resources.
[0051] As indicated above, figure 1 is provided as an example only. Other examples are possible and may differ from what has been described in relation to figure 1.
[0052] Figure 2 shows a block diagram of a project 200 of BS 110 and UE 120, which can be one of the base stations and one of the UEs in figure 1. BS 110 can be equipped with T 234a to 234t antennas, and the UE 120 can be equipped with antennas R 252a to 252r, where, in general, T> 1 and R> 1.
[0053] At BS 110, a transmission processor 220 can receive data from a data source 212 to one or more UEs, select one or more modulation and encoding schemes (MCS) for each UE based, at least in part, on channel quality indicators (CQIs) received from the UE, process (for example, encode and modular) the data for each UE based, at least in part, on the MCS (s) selected for the UE , and provide data symbols for all UEs. The transmission processor 220 can also

21/75 process system information (for example, for semi-static resource segmentation (SRPI) and / or similar information) and control information (for example, CQI requests, concessions, upper layer and / or similar signaling) and provide control symbols and overload symbols. The transmission processor 220 can also generate reference symbols for reference signals (for example, the cell-specific reference signal (CRS)) and synchronization signals (for example, the main synchronization signal (PSS) and synchronization signal (SSS)). The multi-input and multi-output (TX) transmission processor (MIMO) 230 can perform spatial processing (eg pre-coding) for data symbols, control symbols, overload symbols and / or symbols reference, if applicable, and can provide T symbol output streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process a respective stream of output symbols (for example, for OFDM and / or the like) to obtain a stream of output samples. Each 232 modulator can further process (for example, convert to analog, amplify, filter and convert positively) the output sample stream to obtain a downlink signal. Downlink T signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively. According to certain aspects described in more detail below, the synchronization signals can be generated with location coding to transmit additional information.
[0054] In UE 120, antennas 252a to 252r can

22/75 receive downlink signals from BS 110 and / or other base stations, and can provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 can regulate (for example, filter, amplify, negatively convert and digitize) a received signal to obtain input samples. Each demodulator 254 can further process the input samples (for example, for OFDM and / or the like) to obtain the received symbols. A MIMO 256 detector can obtain symbols received from all demodulators R 254a to 254r, perform MIMO detection for received symbols, if applicable, and provide the detected symbols. The receiving processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data collector 260, and provide decoded control information and system information to a controller / processor 280. A channel processor can determine the received reference signal strength (RSRP), the reference signal strength indicator (RSSI), the channel quality indicator (CQI) and / or the like.
[0055] In uplink, at UE 120, a transmission processor 264 can receive and process data from a data source 262 and control information (for example, for reports comprising RSRP, RSSI, RSRQ, CQI and / or similar) from controller / processor 280. The transmission processor 264 can also generate reference symbols for one or more reference signals. Transmission processor symbols 264 can be pre-encoded by a MIMO TX 266 processor, if applicable, processed

23/75 by modulators 254A to 254r (for example, for DFTs-OFDM, CP-OFDM and / or similar) and transmitted to BS 110. In BS 110, uplink signals from UE 120 and other UEs can be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236, if applicable, and further processed by the receiving processor 238 to obtain decoded data and control information sent by the UE 120. The receiving processor 238 can provide the decoded data to a data collector 239 and decoded control information to controller / processor 240. BS 110 can include communication unit 244 and communicate to network controller 130 via communication unit 244. Network controller 130 can include communication unit 244 communication 294, controller / processor 290 and memory 292.
[0056] The controllers / processors 240 and 280 and / or any other component (s) in figure 2 can direct the operation on BS 110 and UE 120, respectively, to carry out the transmission priority indication based on a request configuration. of automatic hybrid repetition (HARQ). For example, controller / processor 280 and / or other processors and modules in BS 110 can perform or direct UE 120 operations to perform the transmission priority indication based on a hybrid auto-repeat request (HARQ) configuration. For example, controller / processor 280 and / or other controllers / processors and modules in BS 110 can perform or direct operations, for example, from

24/75 example process 1400 of figure 14, process 1500 of example of figure 15 and / or other processes, as described in this document. In some aspects, one or more of the components shown in figure 2 can be used to carry out the example process 1400 in figure 14, the example process 1500 in figure 15 and / or other processes for the techniques described herein. Memories 242 and 282 can store data and program codes for BS 110 and UE 120, respectively. The 246 scheduler can schedule
UEs for transmission of downlink data and / or uplink. [0057] How indicated above, The figure 2 is provided only as An example. Others examples are possible and can be different than was described in relation to figure 2.
[0058] Figure 3 shows an example of frame structure 300 for frequency division duplexing (FDD) in a telecommunications system (for example, LTE). The transmission schedule for each of downlink and uplink can be segmented into radio frame units. Each radio frame can have a predetermined duration (for example, 10 milliseconds (ms)) and can be segmented into 10 subframes with indexes from 0 to 9. Each subframe can include two slots. Each radio frame can thus include 20 slots with indexes from 0 to 19. Each slot can include periods of L symbols, for example, seven symbol periods for a normal cyclic prefix (as shown in figure 3) or six periods of L symbols for an extended cyclic prefix. The periods of 2L symbols in each subframe can be assigned indexes from 0 to 2L-1.
[0059] Although some techniques are here
Petition 870190061133, of 7/1/2019, p. 11/29
25/75 described in connection with frames, subframes, slots and / or the like, these techniques can also be applied to other types of wireless communication structures, which can be referred to using different terms of frame, subframe and / or similar in NR 5G. In some respects, a wireless communication structure may refer to a periodic communication unit limited by time defined by a wireless communication standard and / or protocol.
[0060] In some telecommunications (for example, LTE), a BS can transmit a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) on the downlink in the center of the system bandwidth for each cell supported by BS . PSS and SSS can be transmitted in symbol periods 6 and 5, respectively, in subframes 0 and 5 of each radio frame with the normal cyclic prefix, as shown in FIG.
3. PSS and SSS can be used by UEs to search and acquire cells. The BS can transmit a cell-specific reference signal (CRS) through the system bandwidth to each cell supported by the BS. The CRS can be transmitted in certain periods of symbols in each subframe and can be used by the UEs to carry out channel estimation, verification of channel quality and / or other functions. The BS can also transmit a physical transmission channel (PBCH) in symbol periods 0 to 3 in slot 1 of certain radio frames. The PBCH can carry certain information from the system. BS can transmit other system information, such as system information blocks (SIBs) on a physical channel
Petition 870190061133, of 7/1/2019, p. 11/30
26/75 shared downlink (PDSCH) in certain subframes. BS can transmit control / data information on a physical downlink control channel (PDCCH) in the first B symbol periods of a subframe, where B can be configurable for each subframe. The BS can transmit traffic data and / or other data on the PDSCH in the remaining symbol periods of each subframe.
[0061] In other systems (for example, as NR or 5G systems), a Node B can transmit these or other signals at these locations or at locations other than the subframe.
[0062] How indicated above, The figure 3 is provided only as An example. Others examples are possible and can be differ from what was described in relation to figure 3. [0063] Figure 4 shows two formats in subframe 410 and 420 examples with the cyclic prefix normal. The resources of frequency in available time can be targeted at resource blocks sos. Each block in
Features can cover 12 subcarriers in one slot and can include a number of feature elements. Each resource element can cover a subcarrier in a symbol period and can be used to send a modulation symbol, which can be a real or complex value.
[00 64] The subframe format 410 can be used for two antennas. A CRS can be transmitted from antennas 0 and 1 in symbol periods 0, 4, 7 and 11. A reference signal is a signal that is known a priori by a sender and a receiver, and can also be referred to as a pilot. A CRS is a reference signal that is specific

27/75 for a cell, for example, generated based, at least in part, on a cell identity (ID). In figure 4, for a given resource element with Ra mark, a modulation symbol can be transmitted on that resource element from antenna a, and no modulation symbol can be transmitted on that resource element from other antennas. The subframe format 420 can be used with four antennas. A CRS can be transmitted from antennas 0 and 1 in symbol periods 0, 4, 7 and 11 and from antennas 2 and 3 in symbol periods 1 and 8. For both subframe formats 410 and 420, a CRS can be transmitted on evenly spaced subcarriers, which can be determined based on the cell ID. CRSs can be transmitted on the same or different subcarriers, depending on their cell IDs. For both 410 and 420 subframe formats, resource elements not used for CRS can be used to transmit data (for example, traffic data, control data and / or other data).
[0065] The PSS, SSS, CRS and PBCH in LTE are described in 3GPP TS 36.211, entitled Evolved Universal Terrestrial Radio Access (E-UTRA); Physical Channels and Modulation, which is publicly available.
[0066] An interconnection structure can be used for each of downlink and uplink for FDD in some telecommunication systems (for example, LTE). For example, Q interconnections with indexes from 0 to Q - 1 can be defined, where Q can be equal to 4, 6, 8, 10 or some other value. Each interconnection can include subframes that are spaced in Q frames. In particular, the interconnection q may include subframes q, q + Q, q + 2Q and / or the like,
Petition 870190061133, of 7/1/2019, p. 11/31
28/75 where q and {0, Q-l}.
[0066] The wireless network can support hybrid automatic relay request (HARQ) for data transmission on the downlink and uplink. For HARQ, a sender (for example, a BS) can send one or more transmissions of a packet until the packet is correctly decoded by a receiver (for example, a UE) or some other termination condition is met. For synchronous HARQ, all packet transmissions can be sent in subframes of
Single interconnection. For each Asynchronous HARQ, < each streaming of package can to be sent in any subframe. [0067] A UE can be located inside gives roof of several BSs. An of these BSs can to be selected for serve to the UE . THERE 3S service can to be
selected, at least in part, based on several criteria, such as the intensity of the received signal, the quality of the received signal, loss of trajectory and / or similar. The quality of the received signal can be quantified through a signal-to-noise-to-interference ratio (SINR) or a quality received from the reference signal (RSRQ), or another reference. The UE can operate in a dominant interference scenario, in which the UE can observe high interference from one or more interfering BSs.
[0068] Although aspects of the examples described here may be associated with LTE technologies, aspects of the present invention may be applicable to other wireless communications systems, such as NR or 5G.
[0069] New Radio (NR) can refer to radios

29/75 configured to operate according to a new air interface (for example, different from air interfaces based on Orthogonal Frequency Division Multiple Access (OFDMA)) or fixed transport layer (for example, except the Internet Protocol ( IP)). In aspects, NR can use OFDM with a CP (here referred to as cyclic prefix OFDM or CP-OFDM) and / or SC-FDM in the uplink, can use CP-OFDM in the downlink and include support for half-duplex operation using the time division duplexing (TDD). In aspects, NR can, for example, use OFDM with a CP (here referred to as CP-OFDM) and / or orthogonal frequency division multiplexing propagated by Discrete Fourier Transform (DFT-s-OFDM) in the uplink, it can use CP -OFDM in the downlink and include support for half-duplex operation using TDD.
[0070] NR may include the Advanced Mobile Broadband service (eMBB) directed at broadband width (for example, 80 megahertz (MHz) and above), millimeter wave (mmW) directed at high carrier frequency (for example, 60 gigahertz (GHz), massive MTC (mMTC) directed to MTC techniques not compatible with previous versions and / or critical function directed to ultra-reliable low latency communications services (URLLC).
[0071] A single component carrier bandwidth of 100 MHZ can be supported. NR resource blocks can span 12 subcarriers with a subcarrier bandwidth of 75 kilohertz (kHz) for a duration of 0.1 ms. Each radio frame can include 50 subframes with a length of 10 ms. Consequently, each subframe can be 0.2 ms long. Each subframe can indicate a direction of the link (ie DL or

UL) for data transmission and the link direction for each subframe can be changed dynamically. In some respects, a subframe may have a different length and / or may include a different number of slots or mini-slots. Each subframe can include data in DL / UL, as well as control data in DL / UL. The subframes in UL and DL for NR can be described in more detail below with respect to figures 7 and 8.
[0072] The beam formation can be supported and the beam direction can be dynamically configured. MIMO transmissions with pre-coding can also be supported. MIMO configurations in the DL can support up to 8 transmission antennas with multi-layered DL transmissions of up to 8 streams and up to 2 streams per UE. Multilayered transmissions with up to 2 streams per UE can be supported. Multiple cell aggregation can be supported with up to 8 service cells. Alternatively, NR can support a different air interface, except for an OFDM based interface. NR networks can include entities such as central units or distributed units.
[0073] The RAN can include a central unit (CU) and distributed units (DUs). A BS NR (for example, gNB, Node B 5G, Node B, transmit and receive point (TRP), access point (AP)) can correspond to one or more BSs. NR cells can be configured as access cells (ACells) or data cells only (DCells). For example, the RAN (for example, a central unit or distributed unit) can configure the cells. DCells can be cells used for carrier aggregation or connectivity

31/75 double, but not used for initial access, selection / new selection of cells or handover. In some cases, DC cells cannot transmit synchronization signals - in some cases, DCells can transmit SS. NR BSs can transmit downlink signals to UEs indicating the cell type. Based, at least in part, on the cell type indication, the UE can communicate with BS NR. For example, the UE can determine the BSs NR to consider regarding cell selection, access, handover and / or measurement based, at least in part, on the type of cell indicated.
[0074] As indicated above, figure 4 is provided as an example only. Other examples are possible and may differ from what has been described in relation to figure 4.
[0075] Figure 5 illustrates an exemplary logical architecture of a distributed RAN 500, according to aspects of the present invention. An access node 5G 506 can include an access node controller (ANC) 502. The ANC can be a central unit (CU) of the distributed RAN 500. The backhaul interface to the next generation central network (NG-NC) 504 may end at the ANC. The backhaul interface for neighboring next generation access nodes (NG-ANs) may end at the ANC. The ANC may include one or more TRPs 508 (which may also be referred to as BSs, BSs
NR, Nodes B, NBs 5G, APs, gNB or some another term). How described above, one Ί RP can be used so alternating with cell.[0076] The TRPs 508 can Be a unity distributed (DU) . The TRPs can be connected to a ANC (ANC
502) or more than one ANC (not shown). For example, for

32/75 RAN sharing, radio as a service (RaaS), and service-specific AND implementations, the TRP can be linked to more than one ANC. The TRP may include one or more antenna ports. TRPs can be configured to individually (for example, dynamic selection) or together (for example, joint transmission) to deliver traffic to an UE.
[0077] The local architecture of the RAN 500 can be used to illustrate the definition of fronthaul. An architecture that supports fronthauling solutions in different types of deployment can be defined. For example, the architecture may be based, at least in part, on the features of the transmission network (for example, bandwidth, latency and / or jitter).
[0078] The architecture can share resources and / or components with LTE. According to aspects, the next generation AN (NG-AN) 510 can support dual connectivity with NR. The NG-AN can share a common fronthaul for LTE and NR.
[0079] The architecture can allow cooperation between and among the 508 TRPs. For example, the cooperation can be predefined within a TRP and / or through TRPs via ANC 502. According to aspects, an inter-TRP interface can not be needed / present.
[0080] According to aspects, a dynamic configuration of logical division functions may be present within the RAN 500 architecture. The packet data convergence protocol (PDCP), radio link control (RLC) and control protocol access means (MAC) can be adaptably positioned in ANC 702 or

[0081] According to certain aspects, a BS may include a central unit (UC) (for example, ANC 502) and / or one or more units distributed (for example, one or more TRPs 508).
[0082] As indicated above, figure 5 is provided as an example only. Other examples are possible and may differ from what has been described in relation to figure 5.
[0083] Figure 6 illustrates an exemplary physical architecture of a distributed RAN 600, according to aspects of the present invention. A centralized central network unit (C-CU) 602 can host central network functions. C-M3 can be implanted centrally. C-CU functionality can be transferred (for example, to advanced wireless services (AWS)) in an effort to handle maximum capacity.
[0084] A centralized RAN unit (C-RU) 604 can host one or more ANC functions. Optionally, the C-RU can host central network functions locally. The CRU can have a distributed implementation. The C-RU may be closer to the end of the network.
[0085] A distributed unit (DU) 606 can host one or more TRPs. DU can be located at the ends of the network with radio frequency (RF) functionality.

34/75 [0087] Figure 7 is a diagram showing an example 700 of a DLcentric wireless communication structure. The DL-centric wireless communication structure (here also referred to as a DL-centric subframe or a DL-centric slot) can include a control part 702. The control part 702 can exist at the beginning or beginning part of the DL- centric. Control part 702 may include various scheduling information and / or control information corresponding to various parts of the DLcentric slot. In some configurations, the control part 702 can be a physical control channel DL (PDCCH), as shown in figure 7. In some aspects, the information can be carried in a part of the control part 702. In this case, the control part control part 702 can be referred to as a mini-slot. An example of a mini-slot of control part 702 that carries priority information is described with reference to figure 12, below.
[0088] The DL-centric slot can also include a data portion on DL 704. The data portion on DL 704 can sometimes be referred to as the payload of the DLcentric slot. The DL 704 data portion may include the communication resources used to communicate DL data from the scheduling entity (for example, UE or BS) to the subordinate entity (for example, the UE). In some configurations, the data portion in DL 704 can be a DL shared physical channel (PDSCH). In some respects, the data portion in DL 704 can carry network traffic that can be prioritized by another network traffic. For example, the network traffic that is prioritized can be referred to here as the prioritized network traffic, and the other traffic from
Petition 870190061133, of 7/1/2019, p. 39/111
35/75 network that prioritizes network traffic can be referred to as priority network traffic, perforating network traffic, high priority network traffic, and / or the like. In some ways, preemptive network traffic can be associated with ultra-reliable low-latency communications, or a similar service.
[0089] The DL-centric slot can also include a short flashing part in DL 706. The flashing part
short in DL 706 can sometimes be referred how an flashing in UL, a flashing part in UL, an flashing short, one flashing short in UL, an flashing short in UL common, a part intermittent
short in common UL and / or several other suitable terms. In some respects, the short flashing portion at UL 706 may include one or more reference signals. In addition, or alternatively, the short blinking portion on UL 706 may include feedback information corresponding to several other parts of the DL-centric slot. For example, the short flashing portion at UL 706 may include feedback information corresponding to control portion 702 and / or data portion 704. Non-limiting examples of information that may be included in the short flashing portion at UL 706 include a acknowledgment (ACK) (for example, ACK of a physical uplink control channel (PUCCH), ACK of a shared physical uplink channel (PUSCH), an immediate ACK, a negative ACK signal (NACK) (for example, a NACK PUCCH, a NACK PUSCH, an immediate NACK), a scheduling request (SR), a buffer status report (BSR), a HARQ indicator or HARQ response, an indication of the channel status (CSI), an indicator gives

36/75 channel quality (CQI), a poll reference signal (SRS), a demodulation reference signal (DMRS), PUSCH data and / or various other suitable types of information. The short blinking part in UL 706 may include additional or alternative information, such as information regarding random access channel (RACH) procedures, scheduling requests and various other suitable types of information.
[0090] As illustrated in figure 7, the end of the data portion in DL 704 can be separated in time from the start of the short flashing portion in UL 706. This separation in time can sometimes be referred to as an interval, a period guard period, a guard interval and / or several other suitable terms. This separation provides time for the transition from DL communication (for example, receiving operation by the subordinate entity (for example, UE)) to UL communication (for example, transmission by the subordinate entity (for example, the UE). above is just an example of a DL-centric wireless communication structure, and alternative structures
having characteristics similar can exist, without necessarily divert of aspects here des critos.[0091] How indicated above, the figure 7 is provided only as An example. Others examples are
possible and may differ from what has been described in relation to figure 7.
[0092] Figure 8 is a diagram 800 showing an example of a ULcentric wireless communication structure. The UL-centric wireless communication structure (here also referred to as a UL-centric subframe or a
Petition 870190061133, of 7/1/2019, p. 41/111
37/75 UL-centric slot) can include an 802 control part. The 802 control part can exist at the beginning or beginning part of the UL-centric slot. The control part 802 in figure 8 may be similar to the control part 1002 described above with reference to figure 7. In some configurations, the control part 802 may be a physical DL control channel (PUCCH).
[0093] The UL-centric slot can also include a long flashing part in UL 804. The long flashing part in UL 804 can sometimes be referred to as the payload of the UL-centric slot. The UL party may refer to communication resources used to communicate UL data from the subordinate entity (for example, the UE) to the scheduling entity (for example, the UE or the BS).
[0094] As illustrated in figure 8, the end of the 802 control part can be separated in time from the start of the long flashing part in UL 804. This separation in time can sometimes be referred to as an interval, a guard period , a guard interval and / or several other suitable terms. This separation provides time for the transition from DL communication (for example, receiving operation by the scheduling entity) to UL communication (for example, transmission by the scheduling entity. The UL-centric slot can also include a short flashing portion in DL 806. The short flashing part in UL 80 6 in figure 8 can be similar to the short flashing part in UL 706 described above with reference to figure 7, and can include any of the information described above in connection with figure 7. The previous content it is just an example of a structure of
Petition 870190061133, of 7/1/2019, p. 42/111
38/75 UL-centric wireless communication, and alternative structures having similar characteristics can exist, without necessarily deviating from the aspects described here.
[0095] In some cases, two or more subordinate entities (for example, UEs) can communicate with each other using sidelink signals. Real-world applications of such sidelink communications may include public security, proximity services, EU-network relay, vehicle-to-vehicle (V2V) communications, Internet of Everything (loE) communications, loT communications, critical function loop and / or various other suitable applications. Generally, a sidelink signal can refer to a signal communicated from a subordinate entity (for example, UE1) to another subordinate entity (for example, UE2), without relaying that communication through the scheduling entity (for example, UE or BS), although the scheduling entity can be used for scheduling and / or control purposes. In some examples, sidelink signals can be communicated using a licensed spectrum (unlike wireless local area networks, which normally use an unlicensed spectrum).
[0096] In some respects, a wireless communication structure, such as a whiteboard, can include both UL-centric and DL-centric slots. In this example, the ratio of UL-centric slots to DL-centric slots in a frame can be dynamically adjusted based, at least in part, on the amount of UL data and the amount of DL data that is transmitted. For example, if there is more data in UL, then the ratio of UL-centric slots to DL-centric slots can be increased.
Petition 870190061133, of 7/1/2019, p. 43/111
39/75
Conversely, if there is more data in DL, then the ratio of UL-centric slots to DL-centric slots can be decreased. As indicated above, figure 8 is provided as an example only. Other examples are possible and may differ from what has been described in relation to figure 8.
[00 97] Figure 9 is a diagram illustrating an example 900 of providing priority information in relation to prioritized network traffic using a pre-notification or simultaneous notification approach.
[0098] A BS 110 can provide data to a UE 120 on a downlink link with the UE 120. Some data can be associated with a higher priority level than other data. For example, a certain type of data can be provided as part of a low-latency transmission and / or an ultra-reliable transmission, can be associated with a specific service level requirement and / or the like. When BS 110 receives a high priority data type, BS 110 can interrupt the transmission of a lower priority data type to provide the high priority data type, in order to satisfy latency requirements, reliability requirements and / or the like. In this case, the transmission of the high priority data type can be referred to as preemptivity, interruption or perforation of the transmission of the low priority data type.
[0099] When a data transmission is perforated, a recipient UE 120 may fail to decode or process the data transmission. For example, recipient UE 120 can expect to receive data that has been prioritized by data transmission
Petition 870190061133, of 7/1/2019, p. 44/111
40/75 perforating, and can therefore stop processing data transmission. Thus, drilling the data transmission can degrade the downlink performance of the UE 120.
[0100] To obtain data that is prioritized by a high priority data transmission type, the UE 120 can transmit an HARQ response that identifies the data that is prioritized. However, it may be difficult for the UE 120 to identify the data that is prioritized, particularly during progress. In addition, the UE 120 can use significant processor and buffer resources to store and process drilling data, which can be wasted when the drilling data is irrelevant to the UE 120.
[0101] The methods and devices described in this document, for the UE 120, prioritize information that identifies the prioritized network traffic. Priority information can be selectively provided in the same slot as the prioritized network traffic, or in a later slot of the prioritized network traffic based, at least in part, on the possibility of the UE 120 being configured for or capable of HARQ responses of the same slot. For example, priority information can be provided in the same slot as prioritized network traffic when the UE 120 is configured to perform a HARQ response from the same slot (for example, based, at least in part, on a network interconnection structure. UE 120 HARQ), which reduces the time required to set up retransmission of prioritized network traffic. In addition, priority information can be provided as part of a back slot when the UE 120 is configured to perform a HARQ response on
Petition 870190061133, of 7/1/2019, p. 45/111
41/75 subsequent slot (for example, based, at least in part, on a BS 120 HARQ interconnection structure), which saves BS 110 and / or UE 120 resources, and allows priority information are provided as part of a downlink control part of the last slot. In some respects, priority information can be provided at a different periodicity from the prioritized network traffic, and / or can be provided with an offset in relation to the prioritized network traffic, which improves the flexibility of the priority information. In addition, or alternatively, priority information may be provided periodically and / or may be associated with a certain periodicity.
[0102] The figure 9 shows a first type in traffic network 902 that prioritize the transmission of one second kind of traffic network 904. For example, O first kind of traffic from : network 902 can be associated The
ultra-reliable low-latency communications, and the second type of 904 network traffic can be associated with an UE eMBB 120 and / or the like. As shown by reference number 906, the horizontal axis of figure 9 shows time positions of the first type of network traffic 902 and the second type of network traffic 904. As shown by reference number 908, the vertical axis of figure 9 shows frequency bands of the first type of network traffic 902 and the second type of network traffic 904. For example, a BS 110 can schedule and transmit network traffic to a UE 120 in certain time slots or mini-slots ( shown by the horizontal axis), and in particular frequencies or channels (shown by the vertical axis).
Petition 870190061133, of 7/1/2019, p. 46/111
42/75 [0103] As shown by reference number 910, in some respects, priority information can be provided in a frequency band different from network traffic 902 and 904. For example, priority information can be provided in one channel which is separate from or does not overlap with a data channel of UE 120. Priority information is shown by reference number 912. As shown, priority information is provided simultaneously with, or before the first type of 902 network traffic Thus, the UE 120 can identify and process the first type of network traffic 902 according to the priority information. For example, the UE 120 can ignore the first type of network traffic 902, it can buffer the first type of network traffic 902, it can transmit an HARQ response requesting the
second type in traffic in network 904 was prioritized fur first type in traffic in network 902 and / or similar, how described in more Details in connection with figures 11A-13B
below.
[0104] As shown by reference number 914, the first type of network traffic 902 and / or priority information can be provided in one or more mini-slots. A mini-slot can include a part of a slot or subframe. For example, a mini-slot can include one or more symbols, and a slot can include two or more minislots. By providing the first type of 902 network traffic and / or priority information within a mini-slot, BS 110 can reduce the latency of providing priority information. In some respects, BS 110 can provide priority information and / or the first type
Petition 870190061133, of 7/1/2019, p. 47/111
43/75 of network traffic 902 in one or more mini-slots, when the first type of network traffic 902 is associated with ultra-reliable low-latency communication.
[0105] As indicated above, figure 9 is provided as an example. Other examples are possible and may differ from what has been described in relation to figure 9.
[0106] Figure 10 is a diagram illustrating an example 1000 of providing priority information in relation to prioritized network traffic using a post-notification approach. As shown in figure 10, and with reference number 1002, a first type of network traffic 1002 can prioritize a second type of network traffic. In some respects, the first type of network traffic 1002 may correspond to the first type of network traffic 902, and the second type of network traffic may correspond to the second type of network traffic 904.
[0107] As shown by reference number 1004, in some respects, UE 120 can receive priority information after the first type of network traffic 1002 is received. For example, priority information can identify a position (for example, time, frequency, channel, resource block, mini-slot slot, etc.) associated with the first type of network traffic 1002 (for example, based, at least in part, in a slot, mini-slot and / or channel associated with the first type of network traffic 1002 and / or similar). As also shown, in a situation where priority information is received after the first type of network traffic 1002, the priority information can be received on the same channel as the first type of network traffic 1002 and / or the second type
Petition 870190061133, of 7/1/2019, p. 48/111
44/75 of network traffic, or on a channel that is, at least partially, shared with the first type of network traffic 1002 and / or the second type of network traffic. By providing priority information on the same channel, bandwidth resources that would be used to provide priority information on a different channel are saved (for example, when priority information is provided simultaneously with the first type of network traffic 1002, shown in figure 9).
[0108] Figures 9 and 10 describe the priority indication using a simultaneous notification approach and a post-notification approach. However, other positions and configurations of priority information are possible. For example, in some respects, priority information can be provided with a specific offset (for example, in symbols, minislots, slots, subframes, etc.) from the prioritized traffic. As an example, consider that your displacement is 6 mini-slots. In this case, BS 110 can provide priority information with a displacement of 6 minislots from the prioritized traffic. In some respects, priority information can be provided after prioritized traffic based, at least in part, on the specific travel. In some respects, priority information can be provided prior to prioritized traffic based, at least in part, on the specific travel. Providing priority information with a shift can improve time diversity compared to providing priority information simultaneously with prioritized traffic.
Petition 870190061133, of 7/1/2019, p. 49/111
45/75 [0109] In some respects, priority information can be associated with a certain periodicity. For example, priority information can be provided once per subframe, in a specific slot or mini-slot in a subframe, every second subframe, every fifth slot or at other intervals. In this case, the priority information can indicate the prioritized traffic before the traffic is prioritized, simultaneously with the traffic prioritization, after the traffic is prioritized or a combination of these. For example, when priority information is provided periodically, priority information may indicate that a first slot concurrent with priority information is punctured and that a second slot before priority information has been punctured. Providing priority information periodically can improve the predictability of network traffic, thereby simplifying scheduling.
[0110] As indicated above, figure 10 is provided as an example. Other examples are possible and may differ from what has been described in relation to figure 10.
[0111] Figures 11A and 11B are diagrams that illustrate examples 1100 of providing priority information from the same slot to user equipment associated with a HARQ response configuration from the same slot. Figures 11A and 11B describe priority information and network traffic prioritized over slots. In some respects, the slots may include DL-centric slots or subframes, which are described in more detail in connection with the figure above. In addition, or in
Petition 870190061133, of 7/1/2019, p. 50/111
46/75 alternative, the slots can include another type of slot, or a downlink part of a slot. For the purposes of figures 11A and 11B, assume that a BS 110 transmits traffic in a slot to a UE 120. Suppose further that the UE 120 is configured to provide an HARQ response from the same slot.
[0112] As shown in figure 11A, the first type of traffic 1102 can prioritize a second type of traffic 1104. As shown, the first type of traffic 1102 is associated with ultra-reliable low latency communication (URLLC). As also shown, the second type of traffic 1104 is provided in a PDSCH of the slot. In some respects, the PDSCH may correspond to the DL 704 data portion described in relation to figure 7. In some respects, the second type of traffic 1104 may include eMBB and / or similar traffic. In some respects, UE 120 may be a recipient of the second type of traffic 1104, and the first type of traffic 1102 may be destined for another UE 120 or UE 120 which is the recipient of the second type of traffic 1104.
[0113] Therefore, it may be advantageous to indicate to UE 120, using priority information, that the second type of traffic 1104 will be interrupted by the first type of traffic 1102. As shown by reference number 1106, and as described in relation to figure 9 , in some respects, priority information may be provided on a channel or frequency band other than the first type of traffic 1102 and / or the second type of traffic 1104 (shown here using offset in the vertical direction). In this case, priority information can be provided as part of the same slot and / or mini-slot as the first type
Petition 870190061133, of 7/1/2019, p. 51/111
47/75 of traffic 1102. This, in turn, can allow the UE 120 to save buffer and processor resources, which would be used to try to decode the first type of traffic 1102. For example, the UE 120 may not try decode the first type of traffic 1102, it can discard or may not determine the soft bit information associated with the first type of traffic 1102 and / or similar in a situation where, for example, the first type of traffic 1102 is destined for another UE 120.
[0114] In some respects, priority information can be transmitted via broadcast to several different UEs 120. For example, priority information can be provided on a given channel or frequency band. UEs 120 can receive the given channel or frequency band, and can determine whether traffic, routed to UEs 120, has been interrupted or prioritized. When transmitting priority information via broadcast to several different UEs 120, network resources are saved which would be used to transmit separately via unicast the respective priority information to the various different UEs 120. For example, when BS 110 interrupts traffic to several different UEs 120, many resources can be used to generate the respective priority information for each of the UEs 120. BS 110 can save processor resources and network overhead when transmitting via broadcast the priority information that identifies the priorities for all the various different UEs 120.
[0115] BS 110 can provide priority information in the same slot and / or mini-slot when the UE 120 is
Petition 870190061133, of 7/1/2019, p. 11/11
48/75 configured to provide HARQ responses in the same slot. For example, some UEs 120 may be capable of and configured to provide an HARQ response for DL data within the same slot or subframe in which DL data is received. For these UEs 120, BS 110 can provide priority information for the first type of traffic 1102 within the same slot as the first type of traffic 1102. As used in this document, the configuration of the HARQ in the same slot can refer to a configuration to perform a HARQ response within a number of HARQ interconnections that causes UE 120 to provide the response in the same slot as the first type of traffic 1102 (for example, one interconnection, two interconnections and / or the like).
[0116] As shown by reference number 1108, UE 120 can provide a HARQ response within a common UL flashing of the slot in which the first type of traffic 1102 is received. The HARQ response may include a NACK for the second type traffic 1104, to take the second type of traffic 1104 to be retransmitted to UE 120. In some respects, UE 120 can identify the second type of traffic 1104 to be retransmitted based, at least in part, on priority information. For example, priority information can identify mini-slots, resource blocks, frequency bands, specific channels and / or the like, which were prioritized by the first type of traffic 1102. The UE 120 can use the HARQ response to request the retransmission of minislots, resource blocks, frequency bands, specific and / or similar channels. In some respects, the HARQ response may indicate successful receipt of the first
Petition 870190061133, of 7/1/2019, p. 53/111
49/75 traffic type 1102. In some respects, the HARQ response may correspond to the first traffic type 1102 and the second traffic type 1104. For example, the HARQ response may indicate successful receipt of the first traffic type 1102 and failure to receive the second type of traffic 1104. In some respects, the HARQ response may include separate HARQ responses for the first type of traffic 1102 and the second type of traffic 1104. In some respects, the HARQ response may jointly encode a HARQ response for the first traffic type 1102 and a HARQ response for the second traffic type 1104. Thus, the UE 120 provides a HARQ response in the same slot to request the retransmission of interrupted network traffic according to the priority information , which reduces the retransmission latency of interrupted network traffic and improves the downlink performance of the UE 120.
[0117] Figure 11B shows an example in which priority information is received after the first type of network traffic. In figure 11B. priority information is shown by reference number 1110. As also shown, priority information is provided in the same frequency band or bands as the first type of traffic 1102. This can save the frequency resources that would be used to provide priority information on a different channel or frequency band. As shown by reference number 1112, UE 120 provides an HARQ response in the same slot to cause retransmission of parts of the second type of traffic 1104 that have been interrupted, as described in more detail with reference to figure 11A. In this way, the UE 120 provides an
Petition 870190061133, of 7/1/2019, p. 54/111
50/75 HARQ response in the same slot to request retransmission of interrupted network traffic according to priority information, which reduces the latency of retransmission of interrupted network traffic and improves the downlink performance of the UE 120.
[0118] As indicated above, figures 11A and 11B are provided as examples. Other examples are possible and may differ from what has been described in relation to figures 11A and 11B.
[0119] Figure 12 is a diagram illustrating a 1200 example of providing subsequent slot priority information to user equipment associated with a subsequent slot HARQ response configuration. Figure 12 describes priority information and prioritized network traffic in relation to slots. In some respects, the slots may include DL-centric slots or subframes, which are described in more detail in connection with figure 7, above. In addition, or alternatively, the slots may include another type of slot, or a downlink portion of a slot. For the purposes of figure 12, assume that a BS 110 transmits traffic in a slot to a UE 120. Suppose further that the UE 120 is configured to provide an HARQ response in the next slot. In some respects, the UE 120 can be configured to provide a subsequent slot HARQ response, such as a HARQ response (N + 1), an HARQ response N + 2, a HARQ response N + 3 in the next slot and / or the like. As used in this document, a subsequent slot HARQ configuration can refer to a configuration to perform a HARQ response within a number of HARQ interconnects that causes the UE 120 to provide the
Petition 870190061133, of 7/1/2019, p. 55/111
51/75 response in a next slot after traffic is received (for example, three or more interconnections and / or the like).
[0120] As shown in figure 12, the UE 120 receives a first type of traffic 1202 (for example, URLLC traffic and / or similar) that prioritizes a second type of traffic (for example, eMBB traffic and / or similar) during a first slot (for example, a 700-1 DL-centric slot). Here, UE 120 is configured for next slot HARQ response. As a result, UE 120 is not capable of and / or configured to provide an HARQ response to traffic interrupted within the first slot.
[0121] As shown by reference number 1204, when UE 120 is configured to provide an HARQ response in the next slot, BS 110 can provide priority information as part of a second slot (for example, a 700- DL-centric slot) 2) . For example, and as shown, BS 110 can provide priority information as part of a PDCCH for the second slot. In some respects, such as when the PDCCH uses a narrowband configuration, the PDCCH may have unused bandwidth, where priority information can be provided. Thus, the interruption of the DL data pieces of the first slot and the second slot is reduced, which improves the downlink performance of the UE 120. In some respects, priority information can be provided in a different part of the second slot, such as the PDSCH, a channel in the second slot other than a channel associated with the PDSCH and / or the like.
[0122] As shown by the reference number
Petition 870190061133, of 7/1/2019, p. 56/111
52/75
1206, UE 120 provides an HARQ response as part of a common UL flashing of the second slot. For example, the HARQ response can identify traffic, of the second type of traffic, that was interrupted by the first type of traffic 1202. In this way, UE 120 causes the retransmission of the second type of traffic, which improves the downlink performance of the UE 120 when the second type of traffic, forwarded to UE 120, is interrupted. In some respects, the HARQ response may correspond to the first type of traffic 1202. For example, the HARQ response may indicate the successful receipt of the first type of traffic 1202. In some aspects, the HARQ response may correspond to the first type of traffic 1202 and the second type of traffic. For example, the HARQ response may indicate successful receipt of the first type of traffic 1202 and failure to receive the second type of traffic. In some respects, the HARQ response may include separate HARQ responses for the first type of traffic 1202 and the second type of traffic. In some ways, the answer
HARQ can jointly encode an answer HARQ for O first kind of traffic 1202 and an answer HARQ for O according to kind of traffic.[0123] As indicated above, the figure 12 is provided as a example. Others examples are possible and
may differ from what has been described in relation to figure 12.
[0124] Figures 13A and 13B are diagrams that illustrate examples 1300 of retransmission of interrupted network traffic based, at least in part, on a dynamic configuration of a user equipment. For the purposes of figures 13A and 13B, assume that a UE 120
Petition 870190061133, of 7/1/2019, p. 57/111
53/75 is capable of dynamically reconfiguring a HARD configuration of the UE 120. For example, the UE 120 may change from a HARQ configuration in the same slot to a HARQ configuration in a subsequent slot based, at least in part, on available resources, network traffic, expected traffic and / or other factors. As described above, the configuration of the HARQ in the same slot and / or the configuration of the HARQ in a subsequent slot can correspond to different HARQ interconnection structures of the UE 120. As shown in figure 13A, and by reference number 1302, the UE 120 can be associated with a HARQ configuration in the same slot. As shown by reference number 1304, the UE 120 can provide information that identifies the HARQ configuration in the same slot (for example, based, at least in part, on a HARQ interconnection structure of the UE 120) for a BS 110. In some respects, BS 110 may determine the HARQ configuration and / or may provide information that identifies the HARQ configuration for the UE 120 (for example, based, at least in part, on a standard UE 120 configuration , network conditions and / or similar). Suppose the BS 110 stores information that identifies the HARQ configuration in the same slot as the UE 120.
[0125] As shown by reference number 1306, BS 110 can receive low latency network traffic. Low-latency network traffic may include a type of network traffic that will be provided under a particular service level agreement, a latency requirement, a data transfer requirement, a reliability requirement and / or the like. For example, low-latency network traffic can include a type
Petition 870190061133, of 7/1/2019, p. 11/111
54/75
URLLC of network traffic and / or similar.
[0126] As shown by reference number 1308, BS 110 can determine to prioritize network traffic forwarded to UE 120 in slot 0. For example, the type of network traffic to be prioritized can be associated with a lower requirement for priority or latency than the low latency network requirement. Here, the numerology of the slot (for example, slot 0, slot 1, etc.) is selected for illustrative purposes only, and the implementations described in this document are not limited to a particular slot or subframe of a frame.
[0127] As shown by reference number 1310, BS 110 can determine the provision of priority information in the same slot (for example, slot 0) as the prioritized network traffic (for example, the type of network traffic to be prioritized). As shown, BS 110 can provide priority information in slot 0 due to the HARQ response setting in the same slot as the UE 120 (for example, to allow the UE 120 to provide an HARQ response in the same slot to obtain prioritized network traffic ). As shown by reference number 1312, and as described in more detail in connection with figures 9-11B, BS 110 provides priority information in slot 0.
[0128] As shown by reference number 1314, UE 120 identifies the prioritized network traffic (for example, the type of network traffic to be prioritized) using the priority information. For example, priority information can identify resource blocks, slots, mini-slots, channels and / or similar, which have been prioritized
Petition 870190061133, of 7/1/2019, p. 59/111
55/75 for low latency network traffic. As shown by reference number 1316, UE 120 transmits an HARQ response to obtain prioritized network traffic (for example, the type of network traffic to be prioritized). For example, the HARQ response can identify prioritized network traffic to cause BS 110 to relay prioritized network traffic. As shown by reference number 1318, UE 120 provides the HARQ response in slot 0 (for example, the slot in which low latency network traffic has interrupted prioritized network traffic). For example, UE 120 can provide the HARQ response as part of a common UL blink from slot 0.
[0129] As shown by reference number 1320, BS 110 can relay priority network traffic according to the HARQ response. In this way, the UE 120 causes retransmission of the prioritized network traffic using an HARQ response from the same slot according to the priority information received within the same slot in which the prioritized network traffic was scheduled to be received. In addition, in some cases, priority information can be provided simultaneously to or as part of the same mini-slot as priority network traffic, which allows the UE 120 to save processor and buffer resources that would be used to attempt decode and / or process low latency network traffic. For example, in a situation where network traffic in priority is destined for a device other than UE 120, UE 120 may not benefit from decoding network traffic in priority and thus may be advantageous for UE 120 skip decoding or
Petition 870190061133, of 7/1/2019, p. 60/111
56/75 processing network traffic in priority.
[0130] As shown in figure 13B, and with reference number 1322, the HARQ configuration of the UE 120 may change to a HARQ response configuration in the next slot (for example, due to network conditions, the availability of UE resources 120, a traffic forecast, etc.). As shown by reference number 1324, UE 120 can provide information that identifies the changed HARQ configuration, such as the next slot HARQ response configuration, to BS 110 (for example, based, at least in part, on a structure modified HARQ interconnection of UE 120). In some respects, BS 110 can determine the changed HARQ configuration (for example, due to network conditions, the availability of BS 110 and / or UE 120 resources, a traffic forecast, etc.), and can provide the UE 120 information identifying the changed HARQ configuration. As shown by reference number 1326, BS 110 can receive and store the changed HARQ configuration. As shown by reference number 1328, BS 110 receives low latency network traffic (for example, network traffic of a type associated with low latency). As shown by reference number 1330, BS 110 can determine to prioritize network traffic forwarded to UE 120 in slot 0. As indicated above, the numerology of the slot is selected for illustrative purposes only, and the implementations described in this document are not limited to a particular slot or subframe of a radio frame.
[0131] As shown by reference number 1332, BS 110 determines the provision of information
Petition 870190061133, of 7/1/2019, p. 61/111
57/75 priority to UE 120 in a slot after slot 0, due to the UE 120's next slot HARQ response setting. For example, when UE 120 is associated with a next slot HARQ response setting, BS 110 can reduce the interruption of a piece of data in a slot 0 downlink and / or the use of a dedicated channel for priority information by providing the priority information as part of slot 1 (for example, as part of the downlink control information or a Slot PDDCH 1). As shown by reference number 1334, and as described in more detail in connection with figure 12, BS 110 provides priority information in slot 1.
[0132] As shown by reference number 1336, UE 120 identifies prioritized network traffic using priority information. For example, priority information can identify resource blocks, slots, mini-slots, channels and / or the like, which have been prioritized by low latency network traffic. As shown by reference number 1338, UE 120 determines the transmission of an HARQ response that identifies the prioritized network traffic to obtain the prioritized network traffic (for example, to cause the retransmission of the prioritized network traffic). As shown by reference number 1340, the UE 120 provides the HARQ response as part of slot 1. For example, the UE 120 can provide the HARQ response as part of a common UL blink in slot 1. In some respects, the response HARQ can identify network traffic in priority (for example, it can indicate successful receipt of network traffic in priority). In some ways, the HARQ response may
Petition 870190061133, of 7/1/2019, p. 62/111
58/75 identify priority network traffic and priority network traffic.
[0133] As shown by reference number 1342, BS 110 can relay the prioritized network traffic according to the HARQ response. In this way, the UE 120 causes retransmission of the prioritized network traffic using an HARQ response from the next slot according to the priority information received within the next slot after the prioritized network traffic. In addition, priority information can be provided as part of the downlink control information for the next slot, which improves the downlink performance of the UE 120.
[0134] As indicated above, figures 13A and 13B are provided as examples. Other examples are possible and may differ from what has been described in relation to figures 13A and 13B.
[0135] Figure 14 is a flow chart 1400 of a wireless communication method. The method can be carried out
by an UE (for example, O HUH 120 of figure 1 and / or similar). [0136] In 1410, O HUH can receive, in a first position on a signal downlink, information priority that identify an Monday position on one
first type of traffic that prioritizes a second type of traffic, the first position relative to the second position being based, at least in part, on a configuration of the UE's automatic hybrid repeat request (HARQ). For example, the UE can receive, in a first position in a downlink signal, priority information that identifies a second position of a first type of traffic (for example,
Petition 870190061133, of 7/1/2019, p. 63/111
59/75 example, URLLC traffic, and / or similar) that prioritizes a second type of traffic (for example, eMBB and / or similar traffic), on which the first position relative to the second position can be based, at least in part, in a UE HARQ configuration. In some respects, priority information is received periodically. In some respects, the second position is identified based, at least in part, on a shift associated with priority information.
[0137] In 1420, the UE can receive the first type of traffic in the second position. For example, the UE can receive the first type of traffic (for example, URLLC traffic and / or the like) in the second position (for example, where the second type of traffic was scheduled to be received). The first type of traffic can prioritize or interrupt the second type of traffic in the second position.
[0138] In 1430, the UE can generate an HARQ response associated with the first type of traffic. For example, the UE can generate an HARQ response associated with the first type of traffic and / or the second type of traffic. The HARQ response can identify the second type of traffic, and can cause BS to relay the second type of traffic to the UE. In some respects, the HARQ response can identify the first type of traffic, and can indicate that the first type of traffic has been successfully received. In some ways, the HARQ response can identify both the first type of traffic and the second type of traffic.
[0139] In 1440, the UE can transmit the HARQ response based, at least in part, on the UE's HARQ configuration. For example, if the UE HARQ configuration is a
Petition 870190061133, of 7/1/2019, p. 64/111
60/75 configuration of the HARQ in the same slot, then the UE can transmit the HARQ response in the same slot in which the first type of traffic is received. If the HARQ configuration of the UE is a HARQ configuration in a subsequent slot, then the UE can transmit the HARQ response in a slot subsequent to the slot in which the first type of traffic is received.
[0140] In some respects, the HARQ configuration may indicate that the UE is configured to provide a HARQ response in the same slot, and the priority information and the first type of traffic can be received in the same slot in which the second was scheduled. type of traffic to be received based, at least in part, on the UE being configured to provide the HARQ response in the same slot. In some respects, priority information may be received after the moment when the second type of traffic started receiving it. In some respects, the HARQ response can be transmitted for the first type of traffic during an intermittent part of a common uplink in the same slot.

61/75 in a specific slot or mini-slot, and the first type of traffic can be scheduled to be received in the specific slot or mini-slot. In some respects, the HARQ configuration may indicate that the UE is configured to provide the HARQ response associated with the second type of traffic in a subsequent slot after a first slot in which the second type of traffic is received. The first type of traffic can be scheduled to be received in the first slot.

62/75 [0143] In 1510, the base station can determine a configuration of the hybrid automatic repeat request (HARQ) of a user equipment (a UE). For example, the base station may determine a UE HARQ configuration based, at least in part, on receiving information that identifies the HARQ configuration, causing the UE to implement the HARQ configuration and / or the like. The HARQ configuration can include a HARQ response configuration in the same slot, a subsequent HARQ response configuration in a slot, a number of HARQ interconnects or HARQ interconnection structure and / or the like.
[0144] In 1520, the base station provides, in a first position in a downlink signal, priority information that identifies a second position of a first type of traffic that prioritizes a second type of traffic, the first position relative to the second position being with based, at least in part, on the HARQ configuration. For example, the base station can provide, at a first position in a downlink signal, priority information that identifies a second position of a first type of traffic (for example, URLLC and / or similar traffic) that prioritizes a second type of traffic ( eg eMBB and / or similar traffic), where the first position relative to the second position can be based, at least in part, on the configuration of the HARQ. In some respects, the base station may provide priority information periodically.

For example, the base station may provide (for example, transmit to the UE described in connection with block 1520 and / or another UE) the first type of traffic in the second position. Thus, the first type of traffic can prioritize the second type of traffic in the second position.
[0145] In 1540, the base station can receive an HARQ response associated with the first type of traffic. For example, the base station may receive, from the UE, an HARQ response associated with the first type of traffic to cause retransmission of the second type of traffic that was prioritized by the first type of traffic. In some respects, the HARQ response can identify the first type of traffic (for example, it can include an ACK for the first type of traffic) and / or the second type of traffic (for example, it can include a NACK for the second type of traffic) traffic) [0146] In 1550, the base station can transmit the second type of traffic based, at least in part, on the HARQ response. For example, the base station can transmit (for example, provide) the second type of traffic to the UE based, at least in part, on the HARQ response. In some respects, the base station can receive information that identifies a changed UE HARQ configuration. The base station can provide priority information in an altered position in relation to the first type of traffic based, at least in part, on the altered configuration of the HARQ.
