Field of Revelation
[0002] [0002] Aspects of the present disclosure relate to wireless communications and techniques for transmitting uplink control (UCI) information to override uplink resource assignments, such as the physical uplink shared channel (PUSCH) ) and the physical uplink control channel (PUCCH), with repetition in certain systems as in new radio systems (NR). Related Technique Description
[0003] [0003] Wireless communication systems are widely implemented to provide various telecommunication services such as telephony, video, data, messages, broadcasts, etc. These wireless communication systems can employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (for example, bandwidth, transmission power, etc.). Examples of such multiple access systems include 3rd Generation Partner Project (3GPP) Long Term Evolution (3GPP) systems, Advanced LTE systems (LTE-A), code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA), orthogonal frequency division multiple access systems (OFDMA), single carrier frequency division multiple access (SC) systems -FDMA), and multiple access systems by time division synchronous code division (TD-SCDMA), to name a few.
[0004] [0004] In some examples, a wireless multiple access communication system may include several base stations (BSs), which each have the capacity to simultaneously support communication to multiple communication devices, otherwise known as communication equipment. user (UEs). In an LTE or LTE-A network, a set of one or more base stations can define an eNodeB (eNB). In other examples (for example, in a next generation, a new radio (NR), or 5G network), a wireless multiple access communication system may include multiple distributed units (DUs) (for example, edge units (EUs ), edge nodes (ENs), radio heads (RHs), intelligent radio heads (SRHs), transmit reception points (TRPs), etc.) in communication with various central units (CUs) (for example, nodes central
[0005] [0005] These multiple access technologies have been adopted in several telecommunication standards to provide a common protocol that allows different wireless devices to communicate at a municipal, national, regional and even global level. NR (for example, new radio or 5G) is an example of an emerging telecommunication standard. NR is a set of improvements to the mobile LTE standard enacted by 3GPP. NR is designed to support better mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, making use of the new spectrum, and integrating better with other open standards that use OFDMA with a cyclic prefix (CP ) on the downlink (DL) and on the uplink (UL). For these purposes, NR supports beam formation, multiple input and multiple output antenna technology (MIMO) and carrier aggregation.
[0006] [0006] However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in NR technology and

[0026] [0026] Aspects of the present disclosure provide apparatus, methods, processing systems and computer-readable media for NR (new radio access technology or 5G technology). The NR can support several wireless communication services, such as enhanced mobile broadband (eMBB) that targets wide bandwidth (for example, 80 MHz beyond), millimeter wave (mmW) that targets high carrier frequency (for example, 25 GHz or beyond), massive machine-type (MTC) communication that targets non-retrocompatible MTC techniques, and / or mission critical that targets ultra-reliable low-latency communications (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTI) to satisfy the respective quality of service (QoS) requirements. In addition, these services can coexist in the same subframe.
[0027] [0027] In certain systems, such as NR, channels such as the shared physical uplink channel (PUSCH) and physical uplink control channel (PUCCH) can be configured for repetitions. The transmission of uplink control (UCI) information on these channels can be based on rules. Based on the rules, the user equipment (UE) can transmit the UCI in the PUCCH, accumulate the UCI in the PUSCH, or cancel the UCI or a portion of the UCI. In some cases, rules are defined to determine the UCI transmission for the case without repetition (for example, repetition factor = 1); however, due to the fact that in NR the PUSCH and PUCCH can be configured for repetitions (for example, repetition factor = 2, 4, 8, etc.), techniques for applying UCI rules in the case of repetitions are desirable.
[0028] [0028] Consequently, aspects of the present disclosure provide techniques and apparatus for transmitting UCI to overlap PUSCH and PUCCH resource assignments with repetitions.
[0029] [0029] The following description provides examples and is not limited to the scope, applicability or examples presented in the claims. Changes can be made to the function and arrangement of the elements discussed without departing from the scope of the disclosure. Various examples may omit, replace or add various procedures or components, as appropriate. For example, the methods described can be performed in a different order than described and several steps can be added, omitted or combined. In addition, the particularities described in relation to some examples can be combined in some other examples. For example, a device can be implanted or a method can be practiced using a number of aspects set out in this document. In addition, the scope of the disclosure is intended to cover such an apparatus or method, which is practiced with the use of another structure, functionality or structure and functionality, in addition to or in addition to the various aspects of the disclosure presented in this document. It should be understood that any aspect of the disclosure described in this document may be incorporated by one or more elements of a claim. The word "exemplary" is used in this document to mean "that serves as an example, case, or illustration". Any aspect described in this document as "exemplary" should not necessarily be interpreted as preferential or advantageous over other aspects.
[0030] [0030] The techniques described in this document can be used for various wireless communication technologies such as LTE, CDMA, TDMA, FDMA, OFDMA, SC-FDMA and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can deploy radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes broadband CDMA (W-CDMA) and other CDMA variants. Cdma2000 covers IS-2000, IS-95 and IS-
[0031] [0031] New radio (NR) is an emerging wireless communications technology under development in combination with the 5G Technology Forum (5GTF). The Long Term Evolution (LTE) of 3GPP and Advanced LTE (LTE-A) are releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A and GSM are described in documents from an organization called the "Third Generation Partnership Project" (3GPP). Cdma2000 and UMB are described in the documents from an organization called "Project Third Generation Partnership 2 "(3GPP2). The sets of procedures described in this document can be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For clarity, while the aspects can be described in this document using terminology commonly associated with 3G and / or 4G wireless technologies, aspects of this disclosure can be applied to other generation-based communication systems, such as 5G and later, including Exemplary Wireless Communications System
[0032] [0032] Figure 1 illustrates an exemplary wireless communication network 100, in which aspects of the present disclosure can be realized. For example, wireless network 100 can be a new radio (NR) or 5G network. An UE 120 on the wireless communication network 100 can be configured to receive the schedule for the transmission of the physical uplink shared channel (PUSCH)
[0033] [0033] As shown in Figure 1, wireless communication network 100 can include a number of base stations (BSs) 110 and other network entities. A BS can be a station that communicates with user equipment (UEs). Each BS 110 can provide communication coverage for a particular geographic area. In 3GPP, the term "cell" can refer to a coverage area of a Node B (NB) and / or a NB subsystem that serves that coverage area, depending on the context in which the term is used. In NR systems, the term "cell" and next generation NodeB (gNB or gNodeB), access point (AP), or transmission receiving point (TRP) can be interchangeable. In some instances, a cell may not necessarily be stationary, and the cell's geographical area may move according to the location of a mobile BS. In some examples, base stations can be interconnected with each other and / or with one or more other base stations or network nodes (not shown) on wireless communication network 100 through various types of backhaul interfaces as a connection direct physical, a wireless connection, a virtual network or the like using any suitable transport network.
[0034] [0034] In general, any number of wireless networks can be implemented in a given geographical area. Each wireless network can support a particular radio access technology (RAT) and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface, etc. A frequency can also be referred to as a carrier, a subcarrier, a frequency channel, a tone, a subband, etc. 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, NR or RAT 5G networks may be implemented.
[0035] [0035] A BS can provide communication coverage for a macrocell, a picocell, a femtocell, and / or other types of cells. A macrocell can cover a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs with a service subscription. A picocell can cover a relatively small geographical area and can allow unrestricted access by UEs with a service subscription. A femtocell can cover a relatively smaller geographical area (for example, a household) and can allow restricted access by UEs that are associated with the femtocell (for example, UEs a Closed Subscriber Group (CSG), UEs for users at the residence). A BS for a macrocell can be referred to as a macro-BS. A BS for a picocell can be referred to as a pico-BS. A BS for a femtocell can be referred to as a femto-BS or a domestic BS. In the example shown in Figure 1, BSs 110a, 110b and 110c can be macro-BSs for macrocells 102a, 102b and 102c, respectively. The BS 110x can be a pico-BS for a 102x picocell. BSs 110y and 110z can be femto-BS for femtocells 102y and 102z, respectively. A BS can support one or multiple (for example, three) cells.
[0036] [0036] Wireless communication network 100 may also include relay stations. A relay station is a station that receives a transmission of data and / or other information from an upstream station (for example, a BS or a UE) and sends a transmission of the data and / or other information to a downstream station ( for example, a UE or a BS). A relay station can also be a UE that relays transmissions to other UEs. In the example shown in Figure 1, a relay station 110d can communicate with BS 110a and UE 120r 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 eNB, etc.
[0037] [0037] The wireless communication network 100 can be a heterogeneous network that includes BSs of different types, for example, macro BSs, BS peak, BS femto, relays, etc. These different types of BSs can have different transmit power levels, different coverage areas and different impact on interference on the wireless communication network 100. For example, the macro-BS can have a high transmit power level (for example , 20 Watts) while pico-BS, femto-BS and relays may have a lower transmit power level (for example, 1 Watt).
[0038] [0038] A wireless communication network 100 can support synchronous or asynchronous operation. For synchronous operation, BSs can have similar frame timing, and transmissions from different BSs can be aligned approximately in time. For asynchronous operation, BSs may have different frame timing and transmissions from different BSs may not be time aligned. The techniques described in this document can be used for both synchronous and asynchronous operations.
[0039] [0039] A network controller 130 can couple with a set of BSs and provide coordination and control for those BSs. The network controller 130 can communicate with the BSs 110 through a backhaul. BSs 110 can also communicate with each other (for example, directly or indirectly) via a wired or wireless backhaul.
[0040] [0040] 120 UEs (e.g. 120x, 120y,
[0041] [0041] Certain wireless networks (for example, LTE) use orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM partition the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, compartments, etc. Each subcarrier can be modulated with data. In general, the modulation symbols are sent in the frequency domain with OFDM and in the time domain with SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can be dependent on the system bandwidth. For example, the spacing of the subcarriers can be 15 kHz and the minimum resource allocation (called the "resource block" (RB)) can be 12 subcarriers (or 180 kHz). As a result, the nominal Fast Fourier Transfer (FFT) size can be 128, 256, 512, 1024 or 2048 for system bandwidth of 1.25, 2.5, 5, 10 or 20 mega-hertz ( MHz), respectively. The system bandwidth can also be partitioned into sub-bands. For example, a subband can cover 1.08 MHz (ie 6 resource blocks), and there can be 1, 2, 4, 8 or 16 subbands for 1.25, 2 system bandwidth , 5, 5, 10 or 20 MHz, respectively.
[0042] [0042] While the aspects of the examples described in this document may be associated with LTE technologies, aspects of the present disclosure may be applicable with other wireless communications systems, such as NR.
[0043] [0043] NR can use OFDM with a CP on the uplink and downlink and includes support for semi-duplex operation with the use of TDD. The beam formation can be supported and the beam direction can be dynamically configured. Transmission of MIMO with pre-coding can also be supported. The MIMO configurations in the DL can support up to 8 transmission antennas with multi-layered DL transmissions up to 8 streams and up to 2 streams per UE. Multilayer transmissions with up to 2 streams per EU can be supported. Multiple cell aggregation can be supported with up to 8 service cells.
[0044] [0044] In some examples, access to the interface by air can be scheduled. A scheduling entity (for example, a BS) allocates resources for communication between some or all devices and equipment within its service area or cell. 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 allocated by the scheduling entity. Base stations are not the only entities that can function as a scheduling entity. In some examples, a UE can function as a scheduling entity and can schedule resources for one or more subordinate entities (for example, one or more other UEs), and the other UEs can use the resources scheduled by the UE for wireless communication. In some examples, a UE may function as a scheduling entity in a point-to-point (P2P) network, and / or in a mesh network. In an example of a mesh network, UEs can communicate with each other, in addition to communicating with a scheduling entity.
[0045] [0045] 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 on the downlink and / or uplink. A finely dashed line with double arrows indicates interfering transmissions between a UE and a BS. Figure 2 illustrates an exemplary logical architecture of a distributed radio access network (RAN) 200, which can be deployed in the wireless communication network illustrated in Figure 1. A 5G 206 access node can include an access node controller (ANC) 202. ANC 202 can be a central unit (CU) of distributed RAN 200. The backhaul interface for the Next Generation Central Network (NG-CN) 204 can end in ANC
[0046] [0046] The TRPs 208 can be a distributed unit (DU). TRPs 208 can be connected to a single ANC (for example, ANC 202) or more than one ANC (not shown). For example, for RAN sharing, radio as a service (RaaS), and specific implementations and services, TRPs 208 can be connected to more than one ANC. 208 TRPs can each include one or more antenna ports. The TRPs 208 can be configured to serve traffic individually (for example, dynamic selection) or together (for example, joint transmission) to a UE.
[0047] [0047] The distributed RAN 200 logical architecture can support fronthauling solutions across different types of implementation. For example, the logical architecture can be based on transmission network capabilities (for example, bandwidth, latency and / or jitter). The distributed RAN 200 logical architecture can share particularities and / or components with LTE. For example, next generation access node (NG-AN) 210 can support dual connectivity with NR and can share a common fronthaul for LTE and NR. The distributed RAN 200 logical architecture can enable cooperation between and within TRPs 208, for example, within a TRP and / or through TRPs via ANC 202. An inter-TRP interface may not be used.
[0048] [0048] The logic functions can be dynamically distributed in the distributed RAN 200 logical architecture. As will be described in more detail with reference to Figure 5, the Radio Resource Control (RRC) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, Media Access Control (MAC) and a Physical layer (PHY) can be placed adaptively on the
[0049] [0049] Figure 3 illustrates an exemplary physical architecture of a distributed RAN 300, according to the aspects of the present disclosure. A centralized central network unit (C-CU) 302 can host central network functions. The C-CU 302 can be implemented centrally. The functionality of C-CU 302 can be downloaded (for example, for advanced wireless services (AWS)), in an effort to manipulate peak capacity.
[0050] [0050] A centralized RAN unit (C-RU) 304 can host one or more ANC functions. Optionally, the C-RU 304 can host core network functions locally. The C-RU 304 can have a distributed implementation. The C-RU 304 may be close to the network edge.
[0051] [0051] A DU 306 can host one or more TRPs (edge node (EN), edge unit (EU), radio head (RH), smart radio head (SRH), or the like). DU can be located at the edges of the network with radio frequency (RF) functionality.
[0052] [0052] Figure 4 illustrates exemplary components of BS 110 and UE 120 (as depicted in Figure 1), which can be used to deploy aspects of the present disclosure. For example, antennas 452, processors 466, 458, 464, and / or controller / processor 480 of UE 120 and / or antennas 434, processors 420, 430, 438, and / or controller / processor 440 of BS 110 can be used to perform the various techniques and methods described in this document.
[0053] [0053] At BS 110, a transmission processor 420 can receive data from a data source 412 and control information from a controller / processor 440. The control information can be for the Physical Broadcast Channel (PBCH) ), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid ARQ Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), etc.
[0054] [0054] At UE 120, antennas 452a to 452r can receive downlink signals from base station 110 and can provide received signals to demodulators (DEMODs) on transceivers 454a to 454r, respectively. Each demodulator 454 can condition (for example, filter, amplify, subconvert and digitize) a respective signal received to obtain input samples. Each demodulator can further process the input samples (for example, for OFDM, etc.) to obtain received symbols. The MIMO 456 detector can obtain symbols received from all demodulators 454a through 454r, perform MIMO detection on received symbols, if applicable, and provide detected symbols. A receiving processor 458 can process (e.g., demodulate, deinterleave and decode) the detected symbols, provide decoded data for UE 120 to a data collector 460, and provide decoded control information to a controller / processor 480.
[0055] [0055] On the uplink, on UE 120, a transmission processor 464 can receive and process data (for example, for the physical uplink shared channel (PUSCH)) from a data source 462 and control information ( for example, for the physical uplink control channel (PUCCH)) from controller / processor 480. The transmission processor 464 can also generate reference symbols for a reference signal (for example, for the reference signal of resonance (SRS)). The symbols from the 464 transmission processor can be pre-encoded by a TX 466 MIMO processor, if applicable, further processed by demodulators on transceivers 454a to 454r (eg for SC-FDM, etc.), and transmitted to base station 110. At BS 110, uplink signals from UE 120 can be received by antennas 434, processed by modulators 432, detected by a MIMO detector 436, if applicable, and further processed by a processor receiver 438 to obtain decoded data and control information sent by the UE 120. The receiving processor 438 can supply the decoded data to a data collector 439 and the decoded control information to the controller / processor 440.
[0056] [0056] The controllers / processors 440 and 480 can direct the operation on BS 110 and UE 120, respectively. The 440 processor and / or other processors and modules in BS 110 can perform or direct the execution of processes for the techniques described in this document. Memories 442 and 482 can store data and program codes for BS 110 and UE 120, respectively. A scheduler 444 can schedule UEs for data transmission on the downlink and / or uplink.
[0057] [0057] Figure 5 illustrates a diagram 500 that shows examples for deploying a stack of communications protocols, according to aspects of the present disclosure. Communications protocol stacks can be deployed by devices that operate on a wireless communication system, such as a 5G system (for example, a system that supports uplink based mobility). Diagram 500 illustrates a communications protocol stack that includes the RRC 510 layer, a PDCP 515 layer, an RLC 520 layer, a MAC 525 layer, and a PHY 530 layer. In several examples, the layers of a stack Protocols can be implemented as separate software modules, portions of a processor or ASIC, portions of non-colocalized devices connected by a communications link, or various combinations of them. Co-located and non-co-located deployments can be used, for example, in a protocol stack for a network access device (for example, ANs, CUs, and / or DUs) or a UE.
[0058] [0058] A first option 505-a shows a split deployment of a protocol stack, where the deployment of the protocol stack is split between a centralized network access device (for example, an ANC 202 in Figure 2) and device distributed network access (for example, DU 208 in Figure 2). In the first option 505-a, a layer of RRC 510 and a layer of PDCP 515 can be implanted by the central unit, and a layer of RLC 520, a layer of MAC 525, and a layer PHY 530 can be implanted by the DU. In several examples, CU and DU can be co-located or non-co-located. The first option 505-a can be useful in a macrocell, microcell, or picocell implementation.
[0059] [0059] A second option 505-b shows a unified deployment of a protocol stack, in which the protocol stack is deployed on a single network access device. In the second option, the RRC 510 layer, the PDCP 515 layer, the RLC 520 layer, the MAC 525 layer and the PHY 530 layer can each be implanted by
[0060] [0060] Regardless of whether a network access device deploys part or all of a protocol stack, a UE can deploy an entire protocol stack as shown in 505-c (for example, the RRC 510 layer, the PDCP layer 515, the RLC layer 520, the MAC layer 525 and the PHY layer 530).
[0061] [0061] In LTE, the basic transmission time interval (TTI) or packet duration is the 1 ms subframe. In NR, a subframe is still 1 ms, but the basic TTI is referred to as a slot. A subframe contains a variable number of slots (for example, 1, 2, 4, 8, 16, ... slots) depending on the subcarrier spacing. The NR RB is 12 consecutive frequency subcarriers. The NR can support a 15 KHz subcarrier spacing and another subcarrier spacing can be defined in relation to the base subcarrier spacing, for example, 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc. The symbol and slot lengths scale with subcarrier spacing. The CP length also depends on the subcarrier spacing.
[0062] [0062] Figure 6 is a diagram showing an example of a 600 frame format for NR. The transmission time line for each of the downlink and uplink can be partitioned into radio frame units. Each radio frame can have a predetermined duration (for example, 10 ms) and can be partitioned into 10 subframes, each 1 ms, with indexes from 0 to 9. Each subframe can include a variable number of slots depending on the spacing of subcarrier. Each slot can include a variable number of symbol periods (for example, 7 or 14 symbols) depending on the subcarrier spacing. Symbol periods in each slot can be assigned indexes. A mini-slot, which can be referred to as a subslot structure, refers to a transmission time interval that is shorter than a slot (for example, 2, 3 or 4 symbols).
[0063] [0063] Each symbol in a slot can indicate a link direction (for example, DL, UL or flexible) for data transmission and the link direction for each subframe can be switched dynamically. The link directions can be based on the slot format. Each slot can include DL / UL data as well as DL / UL control information.
[0064] [0064] In NR, a block of synchronization signal (SS) is transmitted. The SS block includes a PSS, an SSS and a two-symbol PBCH. The SS block can be transmitted in a fixed slot location, as the symbols 0 to 3 as shown in Figure 6. The PSS and SSS can be used by UEs for cell acquisition and search. PSS can provide semi-frame timing, SS can provide CP length and frame timing. PSS and SSS can provide the cell identity. The PBCH carries some basic system information, such as downlink system bandwidth, timing information within the radio frame, SS intermittency set frequency, system frame number, etc. SS blocks can be arranged in SS blinks to support beam scanning. Additional system information such as, minimum remaining system information (RMSI), system information blocks (SIBs), other system information (OSI) can be transmitted over a physical downlink shared channel (PDSCH) in certain subframes. The SS block can be transmitted up to sixty-four times, for example, with up to sixty-four different beam directions for mmW. Up to sixty-four transmissions from the SS block are referred to as the SS blink set. SS blocks in one SS flash set are transmitted in the same frequency region, while SS blocks in different SS flash sets can be transmitted in different frequency locations.
[0065] [0065] In some circumstances, two or more subordinate entities (for example, UEs) can communicate with each other using side link signals. The real-world applications of these side-link communications may include public security, proximity services, EU-to-network relay, vehicle-to-vehicle (V2V) communications, Internet of Everything (IoE) communications, IoT communications, critical network of mission critical mission mesh, and / or several other suitable applications. In general, a side link signal can refer to a signal communicated from a subordinate entity (eg UE1) to another subordinate entity (eg UE2) without relaying that communication through the scheduling entity (eg , UE or BS), although the scheduling entity can be used for scheduling and / or control purposes.
[0066] [0066] An UE can operate in various radio resource configurations, including a configuration associated with the transmission of pilots using a dedicated set of resources (for example, a dedicated radio resource control state (RRC), etc.) or a configuration associated with the transmission of pilots using a common set of resources (for example, a common RRC state, etc.). When operating in the dedicated RRC state, the UE can select a dedicated set of resources to transmit a pilot signal to a network. When operating in the common state of RRC, the UE can select a common set of resources to transmit a pilot signal to the network. In any case, a pilot signal transmitted by the UE can be received by one or more network access devices, such as an AN, or a DU, or portions thereof. Each receiving network access device can be configured to receive and measure pilot signals transmitted in the common set of resources, and also receive and measure pilot signals transmitted in dedicated sets of resources allocated to the UEs for which the network access device is a member of a network access device monitoring suite for the UE. One or more of the receiving network access devices, or a CU to which the receiving network access device (or devices) transmits the measurements of the pilot signals, can use the measurements to identify service cells to the UEs, or to initiate a service cell change for one or more of the UEs. Exemplary UCI Transmission for Overlapping Uplink Resource Assignments with Repetition
[0067] [0067] Aspects of the present disclosure provide apparatus, methods, processing systems and computer-readable media for NR system (for example, access to new radio or 5G technology). Certain aspects provide techniques for transmitting uplink control (UCI) information in the NR.
[0068] [0068] A base station (for example, as a BS 110 illustrated in wireless communication network 100 in Figure 1) can schedule user equipment (for example, as UE 120 illustrated in wireless communication network 100 in Figure 1) for uplink transmission. For example, BS can schedule the UE for a physical uplink shared channel (PUSCH) transmission and / or a physical uplink control channel (PUCCH) transmission. In certain systems, such as NR, PUSCH and / or PUCCH it can be configured for repetitions. PUSCH and / or PUCCH can be associated with a repetition factor (for example, 1, 2, 4, 8) that specifies the number of transmission time intervals (TTis), as slots, in which the transmission is repeated. The slots can be in a single subframe or in different subframes. Transmissions can be scheduled on particular orthogonal frequency division (OFDM) multiplexed symbols within the slots.
[0069] [0069] Scheduled transmissions may overlap in some or all scheduled slots. Transmitting the overlapping PUSCH and / or PUCCH (for example, simultaneously) in the same slot can result in a maximum power reduction (MPR), a peak to higher average power ratio (PAPR), power transitions within a slot, etc. The rules can be applied to transmit or cancel channels scheduled in slots where transmissions overlap, and / or to accumulate (ie multiplex) UCI on the PUSCH when the PUCCH is canceled.
[0070] [0070] Techniques are desired for rules for which channels to transmit or cancel and when to transmit or cancel UCI when repetitions are configured for PUSCH and / or PUCCH.
[0071] [0071] Consequently, aspects of the present disclosure provide techniques and apparatus for transmitting UCI to overlap PUSCH and / or PUCCH resource assignments with repetition.
[0072] [0072] Figure 7 is a flow diagram illustrating exemplary operations 700 for wireless communications, in accordance with certain aspects of the present disclosure. Operations 700 can be performed by a UE (for example, as one of the UEs 120 illustrated in Figure 1). Operations 700 can be deployed as software components that run and run on one or more processors (for example, processor 480 in Figure 4). Additionally, the transmission and reception of signals by the UE in operations 700 can be enabled, for example, by one or more antennas (for example, antennas 452 of Figure 4). In certain aspects, the transmission and / or reception of signals by the UE may be implemented via a bus interface of one or more processors (for example, processor 480) which obtains and / or emits signals.
[0073] [0073] Operations 700 can start, in 702, receiving scheduling (for example, a resource assignment) to transmit in a PUSCH in a first one or more slots associated with a first number of repetitions (for example, a first repetition factor) and receive scheduling to transmit in a PUCCH in one second one or more slots associated with a second number of repetitions (for example, a second repetition factor). The repetition factor can specify the number of slots in which the associated PUSCH or PUCCH is repeated. A repetition factor of 1 may indicate no repetition (that is, transmission of only 1 slot). The repetitions can be in consecutive slots or in non-consecutive slots. The repetitions can be in slots in the same subframe, in different subframes and / or in different frames. For example, some slots may not have enough UL symbols to transmit (for example, the symbols may have been switched to DL by some other signaling) and those slots may be skipped by repetitions.
[0074] [0074] Scheduled PUSCH and / or PUCCH transmissions overlap in at least one slot (for example, in a partially or completely overlapping set of slots and in a partially or completely overlapping set of OFDM symbols within a slot) .
[0075] [0075] In 704, the EU determines to transmit UCI on the PUSCH (for example, accumulate) and cancel the scheduled PUCCH transmission, transmit the UCI on the PUCCH and cancel the scheduled PUSCH transmission, or cancel the UCI transmission for each of the first and second one or more slots. As described in more detail below, the determination can be based on a rule or set of rules. The rules can depend on several factors, such as a priority level associated with transmissions (as shown in the optional 711 in Figure 7), the nature of the overlapping transmissions (as shown in the optional 812 in Figure 7), content of transmissions, transmission timing , timing of resource assignments for transmissions, etc.
[0076] [0076] In 706, the UE transmits or cancels the UCIs (for example, and the PUSCH and PUCCH) in the first and second one or more slots according to the determination.
[0077] [0077] Figure 8 is a flow diagram illustrating exemplary operations 800 for wireless communication, in accordance with certain aspects of the present disclosure. Operations 800 can be performed by a BS (for example, as a BS 110 on the wireless communication network 100 illustrated in Figure 1). Operations 800 can be complementary operations by BS to operations 700 performed by the UE. Operations 800 can be deployed as software components that run and run on one or more processors (for example, processor 440 in Figure 4). Additionally, the transmission and reception of signals by the BS in operations 800 can be enabled, for example, by one or more antennas (for example, antennas 434 of Figure 4). In certain aspects, the transmission and / or reception of the signals by the BS can be implemented through a bus interface of one or more processors (for example, processor 440) which obtains and / or emits signals.
[0078] [0078] Operations 800 can start, in 802, by scheduling the UE to transmit in the PUSCH in the first one or more slots associated with the first number of repetitions and to transmit in the PUCCH in the second one or more slots associated with the second number of repetitions , where scheduled PUSCH and PUCCH transmissions overlap in at least one slot.
[0079] [0079] In 804, in the first and second one or more scheduled slots, BS receives UCI from the UE in the scheduled PUSCH (for example, accumulated), but does not receive the scheduled PUCCH transmission (for example, due to the fact that PUCCH has been canceled by the UE), or BS receives the UCI at the scheduled PUCCH, but does not receive the scheduled PUSCH transmission (for example, due to the fact that the PUSCH has been canceled by the UE), or the BS may not receive the UCI (for example, due to the fact that the UCIs were canceled by the UE).
[0080] [0080] As mentioned above, the determination by the UE whose channels on which to transmit UCI or cancel can be based on a rule or set of rules. The rules can depend on several factors, such as a priority level associated with the transmissions, the nature of the overlapping transmissions, contents of the transmissions, timing of the transmissions, timing of the resource assignments for the transmissions, etc.
[0081] [0081] The exemplary factors and rules discussed in this document may not be exhaustive and may not be mutually exclusive. Other suitable rules can be used to make the determination and the rules can be based on other suitable factors. The appropriate combinations of rules and factors can be used to make the determination.
[0082] [0082] According to certain aspects, the determination is based, at least in part, on relative priorities of the channels and / or UCI. For example, the determination can be based on a first priority level associated with the UCI and a second priority level associated with the PUSCH.
[0083] [0083] A PUSCH priority level can be based on the respective priority levels of the logical channel (or channels) associated with (for example, having bits loaded) in the PUSCH. For example, PUSCH may be associated with different logical channels for different services, such as enhanced mobile broadband (eMBB) and ultra-reliable low-latency communications (URLLC). In some instances, the priority level for PUSCH is the highest priority level for the associated logical channels. A UCI priority level can be based on a priority level, or a higher priority level, of UCI content (for example, information). In some examples, hybrid automatic retry request priority (HARQ) confirmation (ACK) information (for example, ACK / NACK feedback) is based on the corresponding physical downlink shared channel (PDSCH) priority level being confirmed . In some instances, a scheduling request (SR) priority level is based on the priority level of the logical channel associated with the SR if multiple SR resources corresponding to the different logical channels overlap with the PUSCH resource, the SR included with PUSCH can correspond to the one with the highest logical channel priority or the one with the SR feature that starts earlier.
[0084] [0084] The UE can be configured with the priority to apply to the channels. For example, the UE can be wired, the priority can be specified in the wireless standards and / or the priorities can be flagged for the UE. In some instances, priorities may be, in descending order of priority, ACK / NACK information that has a higher priority, then scheduling requests, a first type of channel state information (e.g., periodic CSI), a second type of CSI (for example, semi-persistent CSI), a third type of CSI (for example, periodic CSI), and then PUSCH data that has the lowest priority. In some examples, a different order of priorities can be configured. For example, SR could be prioritized over ACK if uplink traffic is considered to be more important than downlink traffic.
[0085] [0085] According to certain aspects, the determination by the UE whose channels on which to transmit UCI or cancel is based, at least in part, on the overlap of scheduled transmissions. For example, the determination can be based on whether the transmissions are overlapping intra-slot and / or inter-slots.
[0086] [0086] For intra-slot overlap, the determination is based on whether overlapping transmissions are scheduled for transmission in OFDM symbols within a slot that are completely overlapping (for example, the same set of OFDM symbols in the slot is scheduled for PUSCH and PUCCH) or partially overlapping (for example, some OFDM symbols are scheduled for overlapping transmissions, other OFDM symbols are not). If the transmissions in the slot are only a partially overlapping set of OFDM symbols, then the determination can be further based on which assignment starts before or after and / or which assignment ends before or after. In some examples, transmissions can be scheduled for different OFDM symbols for different slots; Therefore, the intra-slot overlay may be different for different slots.
[0087] [0087] For inter-slot overlap, the determination can be based on whether the scheduled slots are completely overlapping (for example, the same set of slots is scheduled for transmissions) or partially overlapping (for example, some slots overlap, other slots do not). If the scheduling transmissions are only in a partially overlapping set of slots, then the determination can additionally be based on which assignment starts before or after and / or which assignment ends before or after.
[0088] [0088] According to certain aspects, the determination is based, at least in part, on a type of information associated with the UCI (for example, content of the UCI).
[0089] [0089] According to certain aspects, the determination is based, at least in part, on the resource assignments that schedule the overlapping transmissions. For example, the determination can be based on whether resource assignments are semi-static or dynamic and / or a time when resource assignments are received.
[0090] [0090] According to certain aspects, the rule (or rules) can be determined / defined to overlap in a slot (for example, without repetition). The determination for the 1-slot rule can be based on any of the factors discussed above, or a combination of those factors and / or other factors. For complete overlap, the same rule (or rules) can be extended to repeat slots. For example, in each of the scheduled slots, the same rule / determination can be applied for transmission / cancellation of PUSCH / PUCCH / UCI. For partial overlap, the determination for the 1-slot rule can only be applied to overlapping e-slots and not to other slots. In some instances, a channel (for example, PUSCH or PUCCH) may be canceled. The channel can be canceled in every slot, canceled only in overlapping slots, or it can be canceled starting in the first overlapping slot and the remaining slots. The channel to be canceled can be based on a channel priority level, timing of assignments, when assignments are known (for example, received in a semi-static or dynamic way), or a combination of these.
[0091] [0091] In some examples, for partial overlap, assignments received / configured that schedule overlapping transmissions can be adjusted to create (for example, apply or achieve) additional overlap or complete overlap. One or more assignments can be implicitly extended to reduce or eliminate the number of non-overlapping slots. For example, if one of the assignments is semi-static, then the overlap can be predicted as soon as the other assignment (for example, a dynamic assignment for the other channel) is received. Based on the predicted overlap, the semi-static assignment can be extended to override the dynamic assignment. In this case, the rule / determination for a slot can be used for all overlapping slots.
[0092] [0092] In some examples, other adjustments can be made to the assignments to allow for improved processing. For example, if one of the assignments is for a single slot, 1-slot rules can only be applied to that slot. It may be advantageous to move that overlapping slot to the beginning or end of another multi-slot assignment to obtain a contiguous set of slot repetitions with the same structure or to improve the UE processing timeline. In an illustrative example, when a 1-slot PUSCH overlaps an N-slot PUCCH, the 1-slot PUSCH can be moved to the first or last of the N slots, the UCIs are accumulated in the 1-slot PUSCH , and transmitted in the remaining N-1 slots. Whether the PUSCH is moved to the beginning or end of the assignment can be decided by (for example, determined on the basis of) other factors such as, for example, based on the nature of the overlap within the slot (for example, which of the two assignments of resource, PUSCH or PUCCH, has a beginning or end OFDM symbol before). Moving an assignment to a later slot can also improve the processing timeline. For example, if a 1-slot PUCCH overlaps the first slot of a 2-slot PUSCH and the PUSCH starts earlier than the PUCCH, then if UCIs are accumulated in the first slot, UCIs should be available sooner than if there was no overlapping PUSCH.
[0093] [0093] If the payload is not ready, an obsolete / previous payload may be used (for example, old / previous CSI), or the assignment may not be extended, or one of the transmissions may be canceled. In general, as long as the full extension can be honored with sufficient notice for both PUCCH and PUSCH ACK, for example, based on timeline k1 (ie, the gap between PDSCH and the corresponding ACK) and timeline k2 (that is, the gap between the granting of PUSCH allocation and the transmission of PUSCH), so full extension can be allowed. In an illustrative example, a dynamically scheduled 1-slot ACK (ie, set repetition factor of 1) overlaps the third slot of a semi-persistent PUSCH assignment (ie, set repetition factor of 4). The 1-slot ACK assignment can be extended to cover all the slots of the 4-slot PUSCH assignment, as long as the ACK assignment was known sufficiently in advance of the first slot of the 4-slot PUSCH assignment (eg example, based on the minimum k1 value). If the ACK assignment is not sufficiently known in advance to extend to all 4-slot PUSCH assignment slots, then the ACK is not extended or can be extended only to the slots where it is sufficient. In another illustrative example, both the ACK assignment and the PUSCH assignment are scheduled dynamically. If the allocation of
[0094] [0094] According to certain aspects, certain overlaps may not be allowed. For example, gNB may not schedule (for example, avoid scheduling) certain overlaps and the UE may not expect gNB to schedule unallowed overlays.
[0095] [0095] According to certain aspects, the UE may reject one or more assignments (for example, uplink concessions) that schedule PUSCH and PUCCH transmissions in one or more overlapping slots. In some instances, if the lease for one channel is dynamic and the lease for another channel is semi-static, the UE may reject the dynamic lease. In some instances, if the lease for both channels is dynamic, the UE can accept any lease to receive first and reject the lease received later, or the UE can reject the lease that is received first and accept the most recent lease. In some instances, if the lease for one channel is dynamic and the lease for another channel is received at the same time, or if both leases are dynamic, the UE can accept the lease for PUCCH and reject the lease for PUSCH. In some instances, if the PUSCH concession is much less (for example, lower payload capacity) than the PUCCH concession, the UE may reject the PUSCH concession and not accumulate UCI in PUSCH.
[0096] [0096] In some examples, the rules may be a function of the timing of assignments. For example, the relative priorities of PUCCH and PUSCH may be a function of the assignment durations for PUCCH and PUSCH. A shorter duration transmission can be associated with a lower latency requirement and therefore higher priority than a longer duration transmission. Some examples are the short PUCCH (for example, of duration 1 or 2 OFDM symbols) and non-slot PUSCH (for example, type-B which can also be referred to as a mini-slot PUSCH transmission), which can be more prioritized than the long PUCCH (for example, of 4 or more OFDM symbols duration) and slot-based PUSCH (for example, type-A transmission), respectively.
[0097] [0097] When both PUCCH and PUSCH are of the same priority (for example, short PUCCH and non-slot PUSCH, or long PUCCH and slot-based PUSCH), the rules determined to be applied may be different from those when PUCCH and PUSCH are of a different priority. For example, when PUSCH and PUCCH have the same priority, the transmission that starts later in time can be canceled, and when PUSCH and PUCCH have different priorities, even if the higher priority transmission starts later, the earlier transmission can be canceled. or suspended after partial transmission to allow the higher priority transmission to proceed. The suspended transmission can be prevented from resuming within the slot in which the suspension started, even after the higher priority transmission has completed, due to the fact that resuming that transmission may not be possible while maintaining phase coherence with the original portion of the transmission that was sent before suspension. When repetition is configured, the suspended transmission can also be prevented from forming resume in subsequent repeated slots. Alternatively, since each repeated slot has its own demodulation reference signal (DMRS), lower priority transmission may be allowed to resume in subsequent repeated slots.
[0098] [0098] Although the techniques discussed in this document refer to examples of PUSCH and PUCCH, the techniques described in this document can be extended to cases of more than two transmission resources with complete or partial overlap between different subsets of the resources. For example, an N-slot PUCCH can overlap two consecutive PUSCH transmissions. The UCI can be accumulated in one or both of the PUSCH transmissions. In some instances, the PUSCH transmission or transmissions to accumulate the UCIs can be determined based on the nature of the symbol level overlap within the overlapping slots, or on the basis of which of the PUSCH transmissions is of the longest duration. In some examples, PUCCH can also be transmitted in the slots without overlapping PUSCH. The techniques discussed in this document can also be extended to the case where two more transmission features are contained in the same slot. For example, a 1-slot PUCCH can overlap two consecutive or non-contiguous PUSCH streams within the same slot (for example, mini-slot streams). The UCI can be accumulated in one or both of the PUSCH.
[0099] [0099] According to certain aspects, the transmission beam to use for transmissions can be determined. In some examples, the rules for determining the transmission beam or beams for PUCCH and PUSCH transmissions can be determined according to the techniques described in this document. In some examples, in each slot it can first be determined whether the transmission is made in PUCCH or PUSCH (that is, according to the only slot rule for that slot), and then the beam for the corresponding transmission in that slot is determined . This can result in different bundles for different slots, for example, if UCIs are accumulated only in the overlapping slots. Therefore, in some examples, the transmission and transmission beam are determined for the first slot of the transmission and then the beam determined for the first slot is used for all subsequent transmissions in the subsequent slots. Using the same beam can facilitate assumption of phase coherence in the pilot signals (such as DMRS and phase tracking reference signals (PTRS)) through the transmissions, which enable a joint channel and phase noise estimation through the slots.
[0100] [0100] The beam determination techniques described in this document can be applied even for a 1-slot PUCCH assignment that overlaps a 1-slot PUSCH. In some examples, the UE can use the PUCCH beam or the PUSCH beam, and the UE can determine the beam based on several factors, such as whether the transmission occurs in PUCCH or PUSCH, the nature of the UCI, etc. In some examples, the UE can use the PUSCH beam regardless of whether the PUSCH carries only SCH data, only accumulated UCI data, or both SCH and UCL data
[0101] [0101] The beam determination techniques described in this document can also be applied when there is no overlap between PUSCH and PUCCH assignments. In some examples, the UE reuses the beam determined in the first slot in all subsequent slots. In some instances, the beam is updated based on an appropriate beam determination rule. For example, the UE can determine the transmission beam for PUSCH based on a beam indicator in the PUSCH grant, or based on a beam from a recent PUCCH or PDCCH feature if the beam indicator is absent. The recent PUCCH or PDCCH resource can be the same pair for all repeated PUSCH slots, or it can upgrade to consecutive slots if more recent PUCCH or PDCCH resources occur during slot repetitions. The beam associated with the recent PUCCH or PDCCH resource can be updated, for example, based on the control element (CE) signaling of the radio resource control (RRC) or media access control (MAC), during the repetitions of slot. Updates can be included or excluded for the purpose of bundling for repeated PUSCH slots.

[0106] [0106] The methods disclosed in this document comprise one or more steps or actions to achieve the methods. The steps and / or actions of the method can be interchanged with each other without departing from the scope of the claims. In other words, unless a specific order of the steps and actions is specified, the order and / or use of the specific steps and / or actions can be modified without departing from the scope of the claims.
[0107] [0107] As used herein, a phrase that refers to "at least one of a list of items" refers to any combination of these items, including singular numbers. As an example, "at least one of: a, b, or c" is intended to cover: a, b, c, ab, ac, bc, and abc, as well as any combination with multiples of the same element (for example , aa, aaa, aa- b, aac, abb, acc, bb, bbb, bbc, cc, and ccc or any other order from a, b, and c).
[0108] [0108] As used in this document, the term "determine" covers a wide variety of actions. For example, "determine" may include calculating, computing, processing, deriving, investigating, querying (for example, querying in a table, a database or other data structure), certifying and the like. In addition, "determining" may include receiving (for example, receiving information), access (for example, accessing data in a memory) and the like. In addition, "determine" may include resolving, selecting, choosing, establishing and the like.
[0109] [0109] The previous description is provided to allow anyone skilled in the art to practice the various aspects described in this document. Various changes to these aspects will be readily apparent to those skilled in the art, and the generic principles defined in this document can be applied to other aspects. Thus, the claims are not intended to be limited to the aspects shown in this document, but must be in accordance with the total scope consistent with the language of the claims, in which the reference to an element in the singular is not intended to mean “a and only one ”unless specifically stated, but, instead,“ one or more ”. Unless specifically stated to the contrary, the term "some" refers to one or more. All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be covered by the claims. In addition, nothing disclosed in this document is intended to be dedicated to the public, regardless of the fact that such disclosure is explicitly cited in the claims. No claim element shall be construed under the provisions of 35 USC §112 (f), unless the element is expressly cited using the phrase “means for” or, in the case of a method claim, the element is cited as using the phrase “step to”.
[0110] [0110] The various method operations described above can be performed by any suitable means with the ability to perform the corresponding functions. The means may include various hardware and / or software components and / or modules, including, without limitation, a circuit, an application specific integrated circuit (ASIC) or processor. Generally speaking, when there are operations illustrated in the Figures, these operations may have counterpart components plus corresponding function with similar numbering.
[0111] [0111] The various illustrative logic blocks, modules and circuits described in connection with the present disclosure can be implemented or carried out with a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate matrix (FPGA) or other programmable logic device (PLD), distinct gate or transistor logic, distinct hardware components or any combination thereof designed to perform the functions described in this document. A general purpose processor can be a microprocessor, but, alternatively, the processor can be any commercially available processor, controller, microcontroller, or state machine. A processor can also be deployed as a combination of computing devices (for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in combination with a DSP core, or any other such configuration).
[0112] [0112] If implemented in hardware, an exemplary hardware configuration may comprise a processing system on a wireless node.
[0113] [0113] If implemented in software, the functions can be stored or transmitted as one or more instructions or code on a computer-readable medium. The software must be interpreted widely to mean instructions, data, or any combination thereof, regardless of whether it is referred to as software, firmware, middleware, microcode, hardware description language or otherwise. Computer-readable media includes both computer storage media and communication media, including any media that facilitates the transfer of a computer program from one location to another. The processor may be responsible for managing the bus and general processing, including running software modules stored on machine-readable storage media. Computer-readable storage media can be attached to a processor so that the processor can read information and write information to the storage media. Alternatively, the storage media can be an integral part of the processor. For example, machine-readable media can include a transmission line, a data-modulated carrier wave, and / or a computer-readable storage media with instructions stored therein separate from the wireless node, all of which can be accessed by the processor through the bus interface. Alternatively or additionally, machine-readable media or any portion of them can be integrated into the processor, just as the case may be with general log files and / or cache. Examples of machine-readable storage media may include, by way of example, RAM (Random Access Memory), flash memory, ROM (Read-Only Memory), PROM (Programmable Read-Only Memory), EPROM (Memory Only) Erasable and Programmable Read), EEPROM (Electrically Programmable and Erasable Read Only Memory), records, magnetic disks, optical disks, hard disks, or any other suitable storage media, or any combination thereof. Machine-readable media can be incorporated into a computer program product.
[0114] [0114] A software module can comprise a single instruction or many instructions and can even be distributed among several different code segments, between different programs and through multiple storage media. Computer-readable media can comprise several software modules. The software modules include instructions that, when executed by a device such as a processor, cause the processing system to perform various functions. Software modules can include a transmit module and a receive module. Each software module can reside on a single storage device or be distributed across multiple storage devices. For example, a software module can be loaded into RAM from a hard drive when a trigger event occurs. During the execution of the software module, the processor can load some of the cached instructions to increase access speed. One or more lines of cache can then be loaded into a general log file for execution by the processor. When referring to the functionality of a software module below, it will be understood that that functionality is implemented by the processor when executing instructions from that software module.
[0115] [0115] In addition, any connection is properly named a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscription line (DSL) or wireless technologies such as infrared (IR), radio and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL or wireless technologies such as infrared, radio and microwave are included in the media definition. Magnetic disk and optical disk, as used in this document, include compact disk (CD), laser disk, optical disk, digital versatile disk (DVD), floppy disk and Bluray® disk, where magnetic disks generally reproduce data in a magnetic way , while optical discs reproduce data optically with lasers. Thus, in some respects, computer-readable media may comprise non-transitory computer-readable media (for example, tangible media). In addition, for other aspects, computer-readable media may comprise transitory computer-readable media (for example, a signal). The combinations of the above must also be covered by the scope of computer-readable media.
[0116] [0116] Thus, certain aspects may comprise a computer program product to perform the operations presented in this document. For example, such a computer program product may comprise a computer-readable medium that has instructions stored (and / or encoded) in them, the instructions being executable by one or more processors to perform the operations described in this document.
[0117] [0117] In addition, it should be noted that modules and / or other appropriate means to implement the methods and techniques described in this document can be downloaded and / or otherwise obtained from a user terminal and / or basis as applicable. For example, such a device can be coupled to a server to facilitate the transfer of means to perform the methods described in this document. Alternatively, various methods described in this document can be provided through storage media (for example, RAM, ROM, physical storage media such as a compact disc (CD) or floppy disk, etc.), so that a user and / or base station can obtain the various methods by coupling or supplying the storage media to the device. In addition, any other suitable technique for providing the methods and techniques described in this document for a device can be used.
[0118] [0118] It should be understood that the claims are not limited to the precise configuration and components illustrated above. Various modifications, alterations and variations can be made to the arrangement, operation and details of the methods and apparatus described above without departing from the scope of the claims.
