TECHNIQUES AND APPLIANCES FOR MONITORING A CONTROL CHANNEL USING AN AWAKENING SIGN
FUNDAMENTALS
Field [0001] Aspects of the present invention generally relate to wireless communication and, more particularly, to techniques and apparatus for controlling channel monitoring using an alarm signal.
Fundamentals [0002] Wireless communication systems are widely implemented to provide various telecommunication services, such as telephony, video, data, messages and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by 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 (TDMA) systems, frequency division multiple access systems (FDMA), frequency division multiple access systems orthogonal (OFDMA) systems, single-carrier frequency division multiple access systems (SCEDMA), time-division synchronous code division multiple access systems (TD-SCDMA), and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of improvements to the Universal Mobile Telecommunications Standard (UMTS) standard promulgated by the Third Generation Partnership (3 GPP) project.

2/82 [0003] A wireless communication network can include a number of base stations (BSs) that can support communication to a number of user devices (UEs). A UE can communicate with a BS through the downlink and the 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 here, a BS can be referred to as A Node B, a gNB, an access point (AP), a radio head, a transmit receiving point (TRP), a 5G BS, a node B, E / or the like.
[0004] The multiple access technologies above have been adopted in various telecommunications standards for the provision of a common protocol that allows different wireless communication devices to communicate at a municipal, national, regional and even global level. 5G, which can also be referred to as New radio (NR), is a set of improvements to the mobile LTE standard promulgated by the Third Generation Partnership (3 GPP) project. 5G is designed to support better mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, making use of new spectrum, and better integrating with other open standards using OFDM with cyclic prefix (CP) (CP- OFDM) on the downlink (DL), using CP-OFDM and / or SC-FDM (for example, also known as discrete Fourier transform scattering ODEM DFT-s-OFDM) on the uplink (UL), as well as formation of support beam, multiple input and multiple antenna technology

3/82 exits (MIMO) and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in LTE and 5G technologies. Preferably, these improvements should be applicable to other multiple access technologies and to the telecommunication standards that employ these technologies.
[0005] When in an idle mode or a connected mode discontinuous reception mode (CDRX), a UE can introduce a low power state to conserve battery power, and can periodically wake up to monitor a control channel for signals related to the EU, such as pages. However, such control channel monitoring can be resource intensive and can consume battery power because the control channel uses complex signals that include a large amount of information. For example, the UE can wake up, search for signals on the control channel, decode the signals if the signals are found, and determine whether the decoded signals are relevant to the UE. If the decoded control channel signals are not relevant to the UE or if no control channel signal is found, then the battery power used to seek, receive
and decode the signs of channel in control is Wasted.SUMMARY[0006] The techniques described here use one wake-up signal to indicate the a UE if one resource in channel signal control that enough includes information
relevant to the UE. In this way, the UE awakens to effect

4/82 the complex control channel signal processing only when the control channel includes signals relevant to the UE, thus conserving the power and resources of the UE battery. Such techniques are particularly suitable for machine-type communication (MTC) UEs, Narrowband Internet of Things (B-IoT) UEs, and / or the like, which can communicate with a network only occasionally, and which may be located in remote locations where changing or recharging a battery is difficult.

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, drams, robots / robotic devices, and / or the like. MTC UEs, as well as other types of UEs, can be implemented as NB-It (narrowband internet)) devices, optimized MTC (eMTC) devices, LTE Category Devices (LTE-M), machine devices for Machine (M2M), and / or the like.
[00037] It is noted that although aspects can be described here using terminology commonly associated with 3G and / or 4G wireless technologies, aspects of the present invention can be applied in other generation-based communication systems, such as 5G and later, including 5G technologies.
[00038] Figure 1 is a diagram illustrating a network 100 in which aspects of the present invention can be practiced. Network 100 can be an LTE network or some other wireless network, such as a 5G network. Wireless network 100 may include a number of BSs 110 (shown as BS 110 A, BS 110b, BS 110c and BS L 10d) and other network entities. BS is an entity that communicates with user equipment (UEs) and can also be referred to as a base station, a BS 5G, node b, gNB, A 5 GNB, an access point, a TRP, and / or similar. Each BS can provide
Petition 870190090687, of 12/09/2019, p. 11/22
16/82 communication coverage for a specific geographic area. In 3 GPP, the term cell can refer to a BS coverage area and / or a BS subsystem serving that coverage area, depending on the context in which the term is used.
[00039] A BS can provide communication coverage for a macro cell, a peak cell, a femto cell, and / or another type of cell. A macrocell can cover a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs with subscription services. A peak cell can cover a relatively small geographical area and can allow unrestricted access [00040] UEs with subscription to services. A femto cell can cover a relatively small geographical area (for example, a house) and may allow access restricted by UEs having association with the femto cell (for example, UEs in a closed subscriber group (CSG)). A BS for a macro cell can be referred to as a BS macro. A BS for a peak cell can be referred to as a Picto BS. A BS for a femto cell can be referred to as a BS femto or a domestic BS. In the example shown in FIG. 1, A BS 110a can be a macro BS for a macro cell 102a, a BS 110b can be a peak BS for a peak cell 102b, and a BS 110c can be a femto BS For a femto cell 102c. A BS can support one or multiple (for example, three) cells. The terms eNB, base station, 5G BS, gNB, TRP, AP, node b, 5G NB, and cell can be used interchangeably here.

17/82 [00041] 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 Station. In some instances, BSs can be interconnected with each other and / or with one or more other BSs or network nodes (not shown) on access network 100 through various types of backhaul interfaces such as a direct physical connection, a virtual network , 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). A relay station can also be an UE that can relay transmissions to other UEs. In the example shown in Figure 1, the relay station 1 10d can communicate with Macro BS 110a 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 Box, a relay base station, a relay, and / or the like
[00042] Network without thread 100 can Be a network heterogeneous that includes BSs in different types, per example, macro BSs, BSs BSs, Femto BSs, BSs In
retransmission, 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, macro BSs can have a high level of transmission power (for example,
Petition 870190090687, of 12/09/2019, p. 11/24
18/82 example, 5 to 40 Watts) while BSs BSs, femto BSs AND retransmission BSs may have lower transmit power levels (for example, 0.1 to 2 Watts).
[00043] A network controller 130 can couple with a set of BSs and can provide coordination and control for these BSs. The network controller 130 can communicate with the BSs through a transport channel
return. The BSs also can communicate an with the another, for example, direct or indirectly by middle on one channel carriage wireless or wired. [00044] The UEs 120 (e.g., 120a, 120b, 120c) can be dispersed across the network without thread 100, and
each UE can be stationary or mobile. A UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, and / 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 laptop computer, a cordless phone, a local loop wireless (WLL) station, a tablet, a camera, a gaming device, a netbook, a smart book, a speaker, medical device or equipment, biometric sensors / devices, clothing devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (for example, smart ring, smart bracelet), an entertainment device (for example, a music or video device, or a satellite radio), a vehicle component or sensor, meters / smart sensors,

19/82 industrially manufactured equipment, a global positioning system device, or any other suitable device that is configured to communicate wirelessly or wired. Some UEs can be considered for evolved or improved machine-type communication (eMTC) UEs. MTC and eMTC UEs Include, for example, robots, druns, remote devices, such as sensors, meters, monitors, location tags, and / or the like, that can communicate with a base station, another device (for example, device remote), 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) via wired or wireless communication. Some UEs can be considered as Internet Identification (I0T) devices. Some UEs can be considered a Customer Premise Equipment (CPE) [00045] In Figure 1, a solid line with double arrows indicates the desired transmissions between a UE and a serving BS, which is a BS designated to serve the UE in downlink and / or uplink. A dashed line with double arrows indicates potentially interfering transmissions between an UE and a BS.
[00046] In general, any number of wireless networks can be implemented in a given geographical 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.
Petition 870190090687, of 12/09/2019, p. 11/26
20/82
Each frequency can support a Single RAT in a given geographic area in order to avoid interference between wireless networks of different Mice. In some cases, 5G RAT networks can be developed.
[00047] In some examples, access to the air interface can be programmed, in which a programming entity (for example, a base station) allocates resources for communication between some or all devices and equipment within the service area or cell of the programming entity. Within this description, as further discussed below, the programming entity may be responsible for programming, assigning, reconfiguring and releasing resources for one or more subordinate entities. That is, for programmed communication, subordinate entities use resources allocated by the programming entity.
[00048] Base stations are not the only entities that can function as a scheduling entity. That is, in some examples, a UE may function as a programming entity, programming resources for one or more subordinate entities (for example, one or more other UEs). In this example, the UE is functioning as a programming entity, and other UEs use resources programmed by the UE for wireless communication. A UE can function as a programming entity in a point-to-point network (P2P), and / or in an interlacing network. In an example of an interlacing network, UEs can optionally communicate directly with each other in addition to communicating with the programming entity.
[00049] Thus, in a communication network without
Petition 870190090687, of 12/09/2019, p. 11/277
21/82 wire with programmed access to time-frequency resources and having a cellular configuration, a P2P configuration and a mesh configuration, a programming entity and one or more subordinate entities can communicate using the programmed resources.
[00050] The techniques described here use an alarm signal to indicate to an UE 120 whether an incoming control channel signal resource includes information relevant to the UE 120. In this way, the UE 120 awakens to perform signal processing complex control channel only when the control channel includes signals relevant to the UE 120, thus conserving the battery power and resources of the UE 120. Such techniques are particularly suitable for UEs MTC 120, NB-It UEs 120, and / or similar, which can communicate with a network only occasionally, and which can be located in remote locations where changing or recharging a battery is difficult.
[00051] As indicated above, Figure 1 is provided as an example only. Other examples are possible and may differ from what was rightly described in Figure 1.
[00052] Figure 2 shows a block diagram 200 of a base station design 110 and UE 120, which can be one of the base stations and one of the UEs in Figure 1. Base station 110 can be equipped with antennas 234a to 234t , and UE 120 can be equipped with antennas r 252a to 252r, where in general> 1 and r> 1.
[00053] At base station 110, a transmission processor 220 can receive data from a data source 212 to one or more UEs, selecting one or more

22/82 modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (eg, encode and modular) the data for each UE based on the least in part on the MCS (s) selected for the UE, and provide data symbols for all UEs. The transmission processor 220 can also process system information (for example, For semi-static resource partition information (SRPI), and / or similar) and control information (for example, CQI requests, leases, upper layer signaling, and / or similar) and provide overhead symbols and control symbols. The transmission processor 220 can also generate reference symbols for reference signals (for example, CRS) and synchronization signals (for example, the primary synchronization signal (PSS) and the secondary synchronization signal (SSS)). A transmission (TX) multiple input multicast (MIMO) processor 230 can perform spatial processing (for example, pre-coding) on data symbols, control symbols, overhead symbols and / or reference symbols, if applicable, and can provide output symbol streams for modulators (MODs) 232a through 232t. Each modulator 232 can process a respective stream of output symbols (for example, 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 upwardly convert) the output sample stream to obtain a downlink signal. Downlink signals from

23/82 modulators 232a through 232t can be transmitted via antennas 234a through 234t, respectively. According to certain aspects described in more detail below, the synchronization signals can be generated with the location coding to conduct additional information.
[00054] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 E / or other base stations and can provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 can condition (for example, filter, amplify, downwardly 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 similar) to obtain received symbols. A 256 MIMO detector can obtain received symbols From all demodulators 254a A 254r, perform MIMO detection on received symbols if applicable, and provide detected symbols. A receiving processor (RX) 258 can process (e.g., demodulate and decode) the detected symbols provide decoded data for UE 120 to a 260 data warehouse, and provide decoded control information and system information to a controller / processor 280. A channel processor can determine RSRP, RSSI, RSRQ, CQI, and / or the like.
[00055] On the uplink, at UE 120, a transmission processor 264 can receive and process data from a data source 2 62 and control information (for example, for reports comprising RSRP, RSSI, RSRQ, CQI,

Symbols from the transmission processor 264 can be pre-encoded by A MIMO TX 266 processor, if applicable, further processed by modulators 254a to 254r (for example, for DFT-s-OFDM, CP-OFDM and / or the like) and transmitted to base station 1102. At base station 110, uplink signals from UE 120 and others [00057] UEs can be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236, if applicable, and further processed by a processor 238 receiver (RX) to obtain decoded data and control information sent by the UE 120. The RX 238 processor can deliver the decoded data to a data warehouse 239 and the decoded control information to the controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 through communication unit 244. Network controller 130 may include a communication unit 294, a controller / processor 290 and a memory 292.
[00058] The controllers / processors 240 and 280 and / or any other component (s) in figure 2 can direct the operation on the base station 110 and UE 120, respectively, to perform the control channel monitoring using an alarm signal. . For example, controller / processor 280 and / or other processors and modules on base station 110, can run or direct

For example, controller / processor 280 and / or other controllers / processors and modules in BS 110 can perform or direct operations for, for example, method 1100 in Figure 1, method 1200 in Figure 12, and / or other processes described on here. In some respects, one or more of the components shown in Figure 2 can be employed to perform example method 1100 in Figure 11, method 1200 in Figure 12, 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. A programmer 246 can program UEs for data transmission on the downlink and / or uplink.
[00059] As indicated above, Figure 2 is provided as an example only. Other examples are possible and may differ from what was rightly described in Figure 2.
[00060] Figure 3 shows an exemplary frame structure 300 for FDD in a telecommunications system (for example, LTE). The transmission time line for each of the downlink and uplink can be divided into radio frame units. Each radio frame can have a predetermined duration (for example, 10 milliseconds (ms)) and can be divided into 10 subframes with indexes from 0 to 9 [00061] Each subframe can include two partitions. Each radio frame can therefore include 20 partitions with indexes from 0 to 194. Each partition can

26/82 include L symbol periods, for example, seven symbol periods for a normal cyclic prefix (as shown in Figure 3) or six symbol periods for an extended cyclic prefix. The 2L symbol periods in each subframe can be assigned indexes from 0 to 2L -1. While some techniques are described here in connection with frames, subframes, grooves, and / or the like, these techniques can apply equally to other types of
structures in Communication wireless, which can be referred to using terms that not frames , subframe, partition and/ or similar in 5G In some aspects, a structure in Communication without wire can refer to a unity of Communication periodically limited defined per a pattern in Communication wireless and / or protocol. [00062] In certain telecommunications (for example, LTE ), a BS can to transmit a sign of
primary synchronization (PSS) and a secondary synchronization signal (SSS) on the downlink in the center of the system bandwidth for each cell supported by the BS. The 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 Figure 3, the PSS and SSS can be used by the UEs To the search and acquisition of 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 perform channel estimation, quality measurement of

27/82 channel and / or other functions. The BS can also transmit a physical broadcasting channel (PBCH) in periods of symbols 0 to 3 in partition 1 of certain radio frames. The PBCH can carry some information from the system. The BS can transmit other system information such as system information blocks (SIBs) on a shared physical downlink channel (PDSCH) in certain subframes. The BS can transmit control information / data 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 in the PDSCH in the remaining symbol periods of each subframe. In some respects, a wake-up signal can indicate whether the control / data information in the PDCCH is relevant to an UE.
[00063] In other systems (for example, such as 5G systems), a Node B can transmit these or other signals at these locations or at locations other than the subframe.
[00064] As indicated above, Figure 3 is provided as an example only. Other examples are possible and may differ from what was rightly described in Figure 3 [00065] Figure 4 shows two exemplary subframe formats 410 and 420 with the normal cyclic prefix. The available time frequency resources can be divided into resource blocks. Each resource block can cover 12 sub-carriers in one partition and can include a number of resource elements. Each

element in resource can cover an subcarrier in one period in symbols and can to be used to send one symbol in modulation, which can to be a real value or
complex.
[00066] 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 transmitter and a receiver and can also be referred to as a pilot. A CRS is a cell-specific reference signal, for example, generated based, at least in part, on a cellular identity (ID) in FIG. 4, For a given resource element with the label Ra, 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 E 11 and from antennas 2 and 3 in symbol periods 1 and 8. For both subframe formats 410 and 42 0, a CRS it can be transmitted on evenly spaced subcarriers, which can be determined based at least in part on the cell ID CRSs can be transmitted on the same or different subcarriers, depending on their Cell IDs. For both subframe formats 410 and 420, resource elements not used for CRS can be used to transmit data (for example, traffic data, control data, and / or other data).

[00068] An interlacing structure can be used for each of the downlink and uplink for FDD in certain telecommunications systems (for example, LTE). For example, q interlaces 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 interlacing can include subframes separated by q frames. In particular, the interlacing q may include subframes q, q + q, q + 2Q, and / or the like, where q + {0. q -1}.
[00069] The wireless network can support the request for hybrid automatic retransmission (HARQ) for data transmission on the downlink and on the uplink. For HARQ, a transmitter (for example, a BS) can send one or more transmissions from a packet until the packet is correctly decoded by a receiver (for example, a UE) or some other termination condition is encountered. Synchronous HARQ, all packet transmissions can be sent in single interleaved subframes. For asynchronous HARQ, each transmission of the packet can be sent in any subframe.
[00070] An UE can be located within the coverage of multiple BSs. One of these BSs can be selected to serve the UE. The server BS can be selected based, at least in part, on several criteria, such as the received signal strength, the received signal quality, the loss of path, and / or the like. The quality of the received signal can be

30/82 quantified by a signal / noise and interference ratio (SINR), or a received reference signal quality (RSRQ), or some other metric. The UE can operate in a dominant interference scenario in which the UE can observe high interference from one or more interference BSs [00071] Although aspects of the examples described here may be associated with LTE technologies, aspects of the present invention may be applicable to other wireless communication systems, such as 5G technologies [00072] 5G can refer to radios configured to operate according to a new air interface (for example, different from Orthogonal Frequency Division Multiple Access (OFDMA) interfaces based air carriers) or fixed transport layer (for example, other than the Internet Protocol (IP)). In aspects, 5G can use OFDM with CP (here referred to as OFDM with cyclic prefix or CP-OFDM) and / or SC-FDM on the uplink, can use CP-OFDM on the downlink and include support for semi-duplex operation using TDD . In aspects, 5G can, for example, use OFDM with CP (here referred to as CP-OFDM) and / or discrete Fourier transform of orthogonal Fourier transform [00073] Multiplexing (DFT-s-OFDM) in the uplink, CP-OFDM on the downlink and include support for semi-duplex operation using TDD. 5G may include an Enhanced Mobile Broadband service (eMBB) for targeting broadband width (eg 80 megahertz (MHz) and beyond), millimeter wave (mmW)

Each radio frame can include 50 subframes with a length of 10 ms. Consequently, each subframe can have a length of 0.2 ms. each subframe can indicate a connection direction [00075] (eg DL or UL) for data transmission and the connection direction for each subframe can be switched dynamically. Each subframe can include DL / UL data as well as DL / UL control data. The UL and DL subframes for 5G can be as described in greater detail below with due regard to Figures 7 and 8, and can include control channel search space features that map to activate signal features, as described in more detail here in this document.
[00076] Beam formation can be supported and the beam direction can be dynamically configured. MIMO transmissions with pre-coding can also be supported. The MIMO configurations on 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. Multilayered transmissions with up to 2 streams per EU can be supported. The aggregation of multiple cells can

32/82 be supported with up to 8 service cells. Alternatively, 5G can support a different air interface, different from an OFDM based interface. 5G networks can include entities such as central units or distributed units.
[00077] The RAN can include a central unit (CU) and distributed units (DUs). A BS 5G (for example, gNB, 5 g De Node B, Node B, transmit reception point (TRP), access point (AP)) can correspond to one or multiple BSs. 5G cells can be configured as access cells (Acms) or data-only cells [00078] (Dcells). For example, the RAN (for example, a central unit or distributed unit) can configure the cells. Cells can be cells used for carrier aggregation or dual connectivity, but not used for initial access, cell selection / reselection, or handover. In some cases, D cells may not transmit sync signals - in some cases, cells may transmit SS 5G data may transmit downlink signals to the UEs that indicate the cell type. Based, at least in part, on the indication of the cell type, the UE can communicate with BS 5G. For example, the UE can determine 5G BSs to consider cell selection, access, handover, and / or measurement based, at least in part, on the indicated cell type.

The backhaul interface for neighboring next generation access nodes (NG-ANs) can end at ANC. The ANC may include one or more 508 TRPs (which may also be referred to as BSs, 5G BSs, Bs nodes, 5G NBs, APs, gNB, or some other term). As described above, TRP can be used interchangeably with a cell.
[00082] TRPs 508 can be a distributed unit (DU). TRPs can be connected to an ANC (ANC502) or more than one ANC (not shown). For example, for RAN sharing, radio as a service (RaaS) and specific uses and uses of service, TRP can be connected to more than one ANC. The TRP can include one or more antenna ports. TRPs can be configured to receive individually (for example, dynamic selection) or jointly (for example, joint transmission) for traffic to an UE.
[00083] The local architecture of the RAN 500 can be used to illustrate the definition of fronthaul. The architecture can be defined to support access solutions through different types of development. For example, the architecture may be based at least in part on transmission network capabilities (for example,

[00085] The architecture can allow cooperation between TRPs 508. For example, cooperation can be pre-established within a TRP and / or through TRPs via ANC 502. According to aspects, no inter-TRP interface can be needed / present.
[00086] According to aspects, a dynamic configuration of divided logic functions can be present in the architecture of the RAN 500. PDCP, RLC, MAC Protocol can be adaptable in ANC or TRP.
[00087] According to certain aspects, a BS may include a central unit (CU) (for example, ANC 502) and / or one or more units distributed (for example, one or More TRPs 508). Such a BS can transmit wake signals to a UE, as described in more detail here [00088] As indicated above, Figure 5 is provided as an example only. Other examples are possible and may differ from what was rightly described in Figure 5.

A centralized RAN unit (C-RU)) 604 can host one or more ANC functions. Optionally, C-RU can host core network functions locally. C-RU may have distributed development. The C-RU may be closer to the edge of the network.
[00090] A distributed unit (DU) 606 can host one or more TRPs. DU can be located at the edges of the network with radio frequency (RF) functionality.
[00091] As indicated above, Figure 6 is provided as an example only. Other examples are possible and may differ from what was rightly described in Figure 6.
[00092] Figure 7 is a diagram 700 showing an example of a central subframe of DL or wireless communication structure. The central DL subframe may include a control portion 702. The control portion 702 may exist in the initial or initial part of the central DL subframe. The control portion 702 can include various programming information and / or control information corresponding to various parts of the central subframe DL. In some configurations, control portion 702 may be a physical DL control channel (PDCCH), as shown in Figure 7 in some respects, a wake-up signal may indicate whether the PDCCH includes information relevant to a UE, and can be received before the PDCCH in time (for example, in a previous subframe or previously in the same subframe).
Petition 870190090687, of 12/09/2019, p. 42/117
36/82 [00093] The central DL subframe may also include a portion of DL 7 04 data. The DL 704 data portion may sometimes be referred to as the payload of the central DL subframe. The DL 704 data portion Can include the communication features used to communicate DL data from the programming entity (for example, UE or BS) to the subordinate entity (for example, UE). In some configurations, the DL 704 data portion may be a physical DL shared channel (PDSCH).
[00094] The central DL subframe can also include a short burst portion of UL 706. The short burst portion of UL 706 can sometimes be referred to as a UL burst, a UL burst portion, a UL burst common, a short burst, a short UL burst, a short burst of common UL, a short burst portion of common UL, and / or various other suitable terms. In some respects, the short burst portion of UL 70 6 may include one or more reference signals. Additionally, or alternatively, the short burst portion of UL 706 may include feedback information corresponding to various other parts of the central DL subframe. For example, the short burst portion of UL 706 may include feedback information corresponding to control portion 702 and and / or data portion 704. Non-limiting examples of information that may be included in the short burst portion of UL 706 include a ACK signal (for example, a PUCCH ACK, a PUSCH ACK, an Immediate ACK), an aNACK signal (for example, A PUCCH NACK, a PUSCH NACK, an Immediate NACK), an Escalation request (SR ), a temporary storage status report (BSR), a HARQ Indicator, a

The short burst portion of UL 706 may include additional or alternative information, such as information regarding random access channel (RACH) procedures, escalation requests and various other suitable types of information.
[00095] As shown in Figure 7, the end of the DL 704 data portion can be separated in time from the beginning of the short burst portion of UL 706. This time separation can sometimes be referred to as a gap, a period of protection, a guard interval and / or several other suitable terms. This separation provides time for switching from DL communication (for example, the receiving operation by the subordinate entity (for example, UE)) to UL communication (for example, transmission by the subordinate entity (for example, UE)). The foregoing is merely an example of a central DL wireless communication structure, and alternative structures having similar characteristics can exist without necessarily deviating from the aspects described here.
[00096] As indicated above, Figure 7 is provided as an example only. Other examples are possible and may differ from what was rightly described in Figure 7 [00097] Figure 8 is a diagram 800 showing an example of a subframe centered on UL or wireless communication structure. The central UL subframe may include
Petition 870190090687, of 12/09/2019, p. 44/117
38/82 an 802 control part. The 802 control part can exist in the initial or initial part of the central UL subframe. The control portion 802 in Figure 8 may be similar to the control portion 702 described above with reference to Figure 7 in some configurations, the control portion 802 may be a physical DL control channel (PDCCH). In some respects, a wake-up signal can indicate whether the PDCCH includes information relevant to a UE, and can be received before the PDCCH in time (for example, in a previous sub-frame or earlier in the same sub-frame).
[00098] The UL central subframe can also include a UL 804 long burst portion. The UL 804 long burst portion can sometimes be referred to as the UL central subframe payload. The UL part can refer to the communication resources used to communicate UL data from the subordinate entity (for example, UE) to the programming entity (for example, UE or BS).
[00099] As illustrated in Figure 8, the end of the 802 control portion can be separated in time from the beginning of the UL 804 long burst portion. This time separation can sometimes be referred to as a gap, protection period, protection interval and / or various other suitable terms. This separation provides time for switching from DL communication (for example, receiving operation by the programming entity) to UL communication (for example, transmission by the programming entity). The central subframe of UL may also include a short burst portion UL 806. The short burst portion UL 806 in Figure 8 may be similar to the short burst portion UL 706 described above with reference
Petition 870190090687, of 12/09/2019, p. 45/117
39/82 to Figure 7, and can include any of the information described above in connection with Figure 7. It is merely an example of a central UL wireless communication structure and alternative structures having similar characteristics can exist without necessarily deviating from the aspects described here.
[000100] In some circumstances, two or more subordinate entities (for example, UEs) can communicate with each other using side link signals. Real-world applications of such side-link communications may include public security, proximity services, EU-to-network transmission, Vehicle-to-vehicle (V2V) communications, communications without Internet,
It communications, mission critical mesh, and / or several other suitable applications. Generally, 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 programming entity (eg, UE Or BS), even if the programming entity can be used for programming and / or control purposes. In some instances, side link signals can be communicated using a licensed spectrum (unlike wireless local area networks, which typically use an unlicensed spectrum).
[000101] In one example, a wireless communication structure, such as a whiteboard, can include both UL-centered and DL-centered subframes. In this example, the ratio of centric subframes in UL to centric subframes in DL in A VT frame can be
Petition 870190090687, of 12/09/2019, p. 46/117
40/82 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 UL data, then the ratio of centric subframes in UL to centric subframes in DL can be increased. Conversely, if there is more DL data, then the ratio of centric subframes in UL to centric subframes in DL can be decreased [000102] As indicated above, Figure 8 is provided merely as an example. Other examples are possible and may differ from what was rightly described in Figure 8.
[000103] When in an idle mode or a connected mode discontinuous reception mode (CDRX), a UE can introduce a low power state to conserve battery power, and can periodically wake up to monitor a control channel (for example, PDCCH and / or similar) for UE-related signals, such as pages. However, such control channel monitoring can be resource intensive and can consume battery power because the control channel uses complex signals that include a large amount of information. For example, the UE can wake up, search for signals on the control channel, decode the signals if the signals are found, and determine whether the decoded signals are relevant to the UE. If the decoded control channel signals are not relevant to the UE or no control channel signal is detected, then the battery power used to seek, receive and decode the control channel signals is wasted.
Petition 870190090687, of 12/09/2019, p. 47/117
41/82 [000104] The techniques described here use a simple wake-up signal (for example, a bit) to indicate to the UE whether an incoming control channel signal resource includes information relevant to the UE. In this way, the UE awakens to carry out the complex control channel signal processing only when the control channel includes signals relevant to the UE, thus conserving the power and resources of the UE battery. Such techniques are particularly suitable for MTC UEs, NB-It UEs, and / or the like, which can communicate with a network only occasionally, and which can be located in remote locations where changing or recharging a battery is difficult. Figure 9 is a diagram illustrating an example 900 of control channel monitoring using an alarm signal. A wake-up signal can be communicated from a base station to a UE to indicate if a close control channel search space resource (for example, A control channel resource in the time domain, frequency domain, domain code, and / or the like) will include information for the UE, such as a page, data, and / or the like. In some respects, the UE may identify a wake signal resource associated with the UE based at least in part on a control channel search space resource associated with the UE. A wake-up feature can be defined in a time domain (for example, using time division multiplexing), in a frequency domain (for example, using frequency division multiplexing), in a code domain (for example example, using code division multiplexing,
Petition 870190090687, of 12/09/2019, p. 48/117
42/82 using a sequence), and / or the like. The wake-up feature can map to the control channel search space feature and can precede the control channel search space feature. In some respects, the wake-up feature may be in a subframe (or partition) before a subframe (or partition) that includes the search space feature of the control channel. In some respects, the wake-up signal feature may precede the control channel search space feature in the same subframe (or slot). In some respects, a wake-up feature can map to one or more control channel search space features (for example, on one or more carriers, on one or more sets of subframes, and / or the like).
[000105] As shown in Figure 9, an alarm signal group 905 can include multiple alarm signals in different resources (e.g., in the time domain, in the frequency domain, in the code domain, and / or the like). For example, wake-up group 905 may include a first wake-up signal subgroup 910 (shown as the WS 1 subgroup), a second wake-up signal 915 subgroup (shown as [000106] The WS 2 subgroup), a third alarm signal subgroup 920 (shown as the WS 3 subgroup), and / or the like. A wake-up subgroup can include one or more wake-up signals (for example, shown as a first WS1 wake-up signal and a second WS2 wake-up signal). Additionally, or alternatively, the alarm signal subgroups 910, 915, 920 included in the alarm signal group 905 can
Petition 870190090687, of 12/09/2019, p. 11/117
43/82 be configured with a periodicity and / or time shift, shown as a first alarm signal period 925 [000107] (For example, WS 1 period), a second alarm signal period 930 (for example, period WS 2), and a third wake-up period 935 (for example, WS 3 period). In some respects, different groups of wake-up signals can be configured with different periodicities, time offsets, subgroup sizes (for example, number of wake-up signals included in a subgroup), and / or the like. Although the wakeup signal subgroups are shown to be non-overlapping in time, in some respects, a first wakeup signal subgroup may overlap in time with a second wakeup signal subgroup (for example, a wakeup signal subgroup). subsequent awakening).
[000108] As also shown in Figure 9, a first control channel search period (CCSS) 940 can be controlled by the first alarm signal subgroup 910, a second CCSS 945 period can be controlled by the second alarm signal subgroup 915, and a third CCSS Period 950 can be controlled by the third wake signal subgroup 920. When a CCSS resource begins in the first CCSS Period 940, as shown by reference number 955, a UE associated with the CCSS resource can monitor a wake up in the first wakeup subset 910 for an indication of whether the CCSS Resource includes information relevant to the UE. For example, the UE can identify a CCSS resource associated with the UE (for example, as shown by the
Petition 870190090687, of 12/09/2019, p. 50/117
44/82 reference number 955), you can identify an
sign of awakening corresponding to Resource CCSS (for example, 0 seconds signal resource in awakening W2 inside the first sign of awakening [000109] Subgroup 910), and can monitor the
wake-up feature for an indication to monitor the CCSS feature. The UE can selectively monitor the CCSS resource based at least in part on the indication. For example, the UE can initiate an awakening procedure to monitor the CCSS resource when the indication indicates that the CCSS Resource should be monitored, or it can sleep during the CCSS resource when the indication indicates that the CCSS Resource should not be monitored. In this way, the UE can skip the monitoring of a CCSS resource when the CCSS Resource does not include information relevant to the UE, thus conserving the battery power and UE resources.
[000110] As shown, a first UE (for example, UE1) can be associated with a CCSS resource in the first CCSS Period 940. The first UE can monitor an alarm signal in the first alarm signal subgroup 910 to determine whether it monitors the CCSS feature. For example, the first UE can monitor at least one of WS1 or WS2 (for example, depending on a configuration, as described below). As also shown, a second UE (for example, UE 2) can be associated with Two CCSS resources that start in the first CCSS 940 period. In some respects, the second UE can monitor a first wake-up signal in the first wake-up subgroup. 910 (for example, WS1) to determine whether to monitor the first CCSS resource, and can monitor a second
Petition 870190090687, of 12/09/2019, p. 51/117
45/82 wake up in the first wakeup signal subgroup 910 (for example, WS2) to determine whether to monitor the second CCSS resource. In some respects, the second UE can monitor a single wake-up signal (for example, WS1) to determine whether the first CCSS resource and the second CCSS resource. For example, a single wake-up signal can correspond to multiple CCSS Resources (for example, indicated by a number of CCSS Resources, a period of time associated with one or more CCSS Resources, and / or the like). In some respects, the size of the wake-up signal subgroup may correspond to a maximum number of CCSS resources, associated with a Single UE, which occurs in a CCSS period. As also shown, a third UE (for example, UE 3) is associated with a CCSS resource in the first CCSS 940 period, and can monitor the first 910 wake-up signal subgroup in a manner similar to that described in connection with the First UE.
[000111] When a CCSS resource begins in the second CCSS Period 945, as shown by reference number 960, a UE associated with the CCSS resource can monitor a wake-up signal in the second wake-up signal 915 subgroup for an indication of whether the CCSS Resource includes information relevant to the UE. For example, the first UE and the second UE can monitor the second alarm signal subgroup 915 in a manner similar to that described above in connection with the first alarm signal subgroup 910. However, the third UE is not associated with any resources CCSS in the second CCSS Period 945. In this case, the third UE can skip the monitoring of the second alarm signal subgroup 915, as well
Petition 870190090687, of 12/09/2019, p. 11/11
46/82 conserving additionally the battery power and resources of UE. In some respects, the UE (s) may receive referrals from a base station that indicates CCSS resources.
[000112] When a CCSS resource begins in the third CCSS Period 950, as shown by reference number 965, a UE associated with the CCSS resource can monitor an alarm signal in the third alarm signal subgroup 920 for an indication of whether the CCSS Resource includes information relevant to the UE. For example, the first UE, the second UE, and the third UE can monitor the third alarm signal subgroup 920 in a manner similar to that described above in connection with the first alarm signal subgroup 910.
[000113] As shown by reference number 970, in some respects there may be a margin (for example, a time margin) between the end of a wake-up signal subgroup and the start of a CCSS period and / or a first CCSS resource that occurs in the CCSS period. This margin may allow sufficient time for the wake-up signal to be processed by one or more UEs before the occurrence of a CCSS resource associated with one or more UEs.
[000114] As also shown in Figure 9, in some respects, the wake-up signal subgroup (for example, a wake-up signal subgroup location) can occur before a corresponding CCSS location of a UE without any sub-groups of wake signals. awaken actors associated with the UE. In this way, latency can be reduced and the UE and the base station do not need to process data beforehand compared to using a
Petition 870190090687, of 12/09/2019, p. 53/117
47/82 wake-up subgroup that occurs a long time before the CCSS feature.
[000115] In some ways, a wake-up feature can map to multiple CCSS features. In some respects, multiple CCSS resources can be associated with a single UE. For example, the first subset of 910 wake signals can map into two CCSS resources associated with the second UE. Additionally, or alternatively, multiple CCSS resources can be associated with multiple UEs. For example, the first 910 wakeup subset can map to a CCSS resource associated with the first UE, two CCSS Resources associated with the second UE, and a CCSS Resource associated with the third UE. In some respects, a wake-up signal can be used to control the monitoring of CCSS resources for multiple UEs, thus conserving network resources compared to using separate wake-up signals for each UE.
[000116] In some respects, a UE may identify a wake-up feature corresponding to a CCSS feature based at least in part on a periodicity or time offset associated with the wake-up feature. For example, the wake-up feature may have a time offset compared to a CCSS period limit, a CCSS resource limit, and / or the like. In addition, different alarm signal resources can be separated in time according to a periodicity. In some respects, time deviation and / or periodicity can be signaled to the UE By a base station
Petition 870190090687, of 12/09/2019, p. 54/117
48/82 [000117] In some respects, a UE can be mapped to a group of wake-up signals (for example, one or more wake-up signal resources) based at least in part on one or more factors. In this case, a base station can transmit multiple wake-up signals in different resources or groups, and can assign UEs to different resources or groups based at least in part on one or more factors. A factor may include, for example, a UE identifier associated with a UE, a temporary radio network [000118] Identifier (RNTI) associated with control channel communications monitored by a UE, a Signal to noise ratio (SINR) associated with a UE, a maximum repetition level associated with a UE, an actual repetition level associated with control channel communications to the UE, a carrier index associated with a CCSS resource associated with the UE, and / or the like. In some respects, if an UE identifier is used to designate UEs to activate signal groups, the UE identifier bits used for assignment may be different from the UE identifier bits used to designate UEs to paging groups (for example, example, to receive pages). In this way, the wake-up feature may be different for Different UEs that monitor the same paging feature, thereby reducing false radio call hopes. In some respects, if the UE monitors multiple RNTIs for the PDCCH, and the wake-up feature depends on the RNTI, then the UE can monitor only one wake-up feature for all the RNTIs monitored by the UE. In this case, the base station can
Petition 870190090687, of 12/09/2019, p. 55/117
49/82 send an alarm signal resource corresponding to an RNTI, but you can send the Real PDCCH using a Different RNTI. Alternatively, the UE can monitor different wake-up resources for different RNTIs.
[000119] In some respects, such mapping of UEs to awaken signal groups can improve performance [000120] For example, a first wake-up signal group may have a short periodicity, with wake-up signals being transmitted more frequently than one second group of alarm signal with a long periodicity. In this case, the base station can map UEs with Low SINR (for example, less than a threshold), a high repetition level for repeated communications (for example, a maximum or actual repetition level that is greater than a threshold ), and / or similar, for the first wake-up group. As a result, UEs associated with poor network conditions are more likely to receive a wake-up signal because of the lower frequency. Conversely, the base station can map UEs with High SINR (for example, greater than a threshold), a low repetition level for repeated communications (for example, a maximum or actual repetition level that is less than a threshold) , and / or similar, for the second wake-up group. In this way, UEs associated with good network conditions can conserve battery power and UE resources because of the higher frequency.
[000121] In some respects, the wake-up signal can be transmitted on a fixed resource, thereby reducing the EU power required to monitor the
Petition 870190090687, of 12/09/2019, p. 56/117
50/82 wake-up signal. In some respects, the wake-up signal can be transmitted across multiple resources, and the UE can monitor multiple resources, which can increase programming flexibility at the expense of the UE's energy consumption. In some aspects, the wake-up signal can be transmitted using temporal diversity (for example, by breaking the wake-up signal or multiple wake-up signals in multiple blocks transmitted with intervening time frames). For example, the wake-up signal can be transmitted using spatial frequency block encoding (SFBC), space time transmission diversity (STTD), beam scanning, and / or the like. In addition, or alternatively, the wake-up signal can be transmitted using frequency diversity (For example, using frequency hopping for different wake-up signals).
[000122] As indicated above, Figure 9 is provided as an example. Other examples are possible and may differ from what was rightly described in Figure 9 [000123] Figure 10 is a diagram that illustrates another example 1000 of control channel monitoring using an alarm signal. As described above in connection with Figure 9, a wake-up signal can be communicated from a base station to a UE to indicate whether a nearby CCSS resource [000124] (For example, a PDCCH search space resource) will include information for the UE, such as a page and / or similar. In some respects, the UE may identify a wake signal resource associated with the UE based at least in part on a CCSS resource
Petition 870190090687, of 12/09/2019, p. 57/117
51/82 associated with the UE. The wake-up feature can map to the CCSS feature and can precede the control channel's search space feature.
[000125] As shown by reference number 1005, in some respects, a wake-up feature can occur in a pre-configured time period before a CCSS feature. The pre-configured time period can be, for example, a number of subframes (or partitions) before the CCSS and / or similar feature. In this case, the UE can identify the wake-up feature based at least in part on a corresponding CCSS feature and the number of subframes. In some ways, the base station can signal the pre-configured time period (for example, The number of subframes) to the UE. In addition, or alternatively, the preconfigured time period can be determined based at least in part on at least one of a UE associated SINR, a maximum repetition level of the control channel associated with the UE, an actual repetition level associated with control channel communications to the UE, and / or the like. For example, a UE associated with a low SINR and / or a high level of repetition can be configured to use a larger number of subframes between KT the wake-up feature and the CCSS feature to provide an opportunity for repetition of the wake-up signal. wake up before the CCSS Appeal. Conversely, a UE associated with a High SINR and / or a low level of repetition can be configured to use a smaller number of LT subframes between the wake-up feature and the CCSS feature because wake-up repetitions may not be needed.
Petition 870190090687, of 12/09/2019, p. 11/117
52/82 [000126] In some respects, Different UEs associated with the same CCSS resource can monitor different wake signals included in a wake signal subgroup that corresponds to the CCSS resource. For example, a first UE can monitor a first wake-up signal in the wake-up signal subgroup to determine whether it monitors the CCSS resource, and a second UE can monitor a second wake-up signal in the wake-up signal subgroup to determine whether it monitors the CCSS feature. In this way, network resources can be conserved by allowing multiple UEs to monitor the same wake signal subgroup, instead of using different wake signal subgroups for different UEs.
[000127] By using an alarm signal feature that a configurable number of subframes (or partitions) occur before a corresponding CCSS feature, the programming delay can be reduced. For example, a base station may be able to make programming decisions for communications closer than when communications are actually sent, thereby improving the use of network resources during programming.
[000128] In some respects, the base station can signal an alarm signal mode to the UE, and / or the base station and the UE can negotiate an alarm signal mode. In some respects, a first wake-up mode may use a wake-up subset to provide indications for CCSS features included in a CCSS period, as described above in connection with Figure 9 In some respects, a second wake-up mode wake-up call can use a wake-up signal before each
Petition 870190090687, of 12/09/2019, p. 59/117
53/82 CCSS feature, no intervening CCSS features, As described in connection with Figure 10 in some respects, the wake-up signal mode can be determined based, at least in part, on whether the wake-up signal is being used for paging , CDRX, a particular type of RNTI, and / or the like. In some ways, both wake-up modes can be used together. For example, the first wake-up mode can be used for the first CCSS resource for a UE within a CCSS Period, and the second wake-up mode can be used for additional CCSS resources for the UE within the CCSS Period. .
[000129] In some respects, the configuration information associated with the wake-up signal can be included in a master information block, a system information block, a broadcast communication (for example, in CDRX), and / or the like. The configuration information may include, for example, a periodicity, a number and / or configuration of alarm signal groups, a number and / or configuration of alarm signal subgroups, a margin and / or the like.
[000130] In some respects, the presence of an alarm signal in an alarm signal resource may indicate that a corresponding CCSS resource includes information relevant to a UE that monitors the alarm signal. In this case, the UE can be configured to monitor the CCSS resource when an alarm signal is present on the alarm signal resource. Additionally, or alternatively, the absence of a wake-up signal in a wake-up feature may indicate that a
Petition 870190090687, of 12/09/2019, p. 60/117
54/82 corresponding CCSS resource does not include information relevant to a UE that monitors the wake-up signal [000131] In this case, the UE can be configured to skip monitoring of the CCSS resource when a wake-up signal is absent from the wake-up signal feature . In this way, a base station can prevent the transmission of an alarm signal when a corresponding CCSS resource does not include information relevant to the UE, thus conserving network resources. In some aspects, the base station can transmit multiple wake-up signals corresponding to different groups of UEs in the same period of time, the same frequency and / or similar. Alternatively, the presence of a wake-up signal in a wake-up signal resource may indicate that a corresponding CCSS resource does not include information relevant to a UE that monitors the wake-up signal AND the absence of a wake-up signal in a wake-up resource wake-up may indicate that a corresponding CCSS resource includes information relevant to a UE monitoring the wake-up signal [000132] In some respects, a first bit value in the wake-up signal (for example, 1) may indicate that the CCSS resource should be monitored because the CCSS Resource includes information relevant to the UE, and a second bit value in the wake-up signal (for example, 0) may indicate that the CCSS resource should be skipped because the CCSS resource does not include information relevant to the UE. In some ways, a single bit can be used for the wake-up signal. In some ways, multiple bits can be used for the wake-up signal. In some ways, a
Petition 870190090687, of 12/09/2019, p. 61/117
55/82 payload size (for example, a number of bits) of the wake-up signal can be less than a number of bits used for legacy downlink control (DCI) information. For example, a legacy DCI payload (for example, a PDCCH payload) can be 23 bits (for example, for NB-It devices), and the size of the wake-up payload can be, for example , bits, 2 bits, 3 bits, 4 bits, 5 bits, and / or the like. Since the number of resources (eg Subframes) to be monitored to decode the increase in PDCCH with the number of payload bits, using a lower payload would help to reduce the number of monitored resources. In this way, the UE can save energy by monitoring fewer subframes or resource elements. In some aspects, the DCI Sent with the wake-up signal can be sent in the same search space as the Legacy DCI. In some respects, the DCI Sent with the wake-up signal can be sent in a search space earlier than the Legacy DCI. In some respects, the DCI Sent with the wake-up signal can be sent in a different search space than the Legacy DCI [000133] In some respects, a bit (s) value may indicate A specific CCSS resource to be monitored when the wake-up signal corresponds to multiple CCSS resources. For example, a first value may indicate that the UE should monitor only a first CCSS resource corresponding to the wake-up signal, a second value may indicate that the UE should monitor only a second CCSS resource corresponding to the wake-up signal, a third value may indicate whereas the UE must monitor both
Petition 870190090687, of 12/09/2019, p. 62/117
56/82 first and second CCSS Resources, a fourth value (or the absence of a wake-up signal) may indicate that the UE should skip monitoring all corresponding CCSS resources, and / or the like.
[000134] In some respects, one or more payload bits of the wake-up signal may indicate at least one of monitoring a corresponding CCSS resource, one or more UEs (for example, indicated by a UE identifier, an RNTI, and / or similar) that are to monitor the corresponding CCSS resource, one or more resources (for example, a vehicle, a search space, a subframe, a partition, a time resource, a frequency resource, and / or the like) where the control channel is enabled, one or more parameters to be used to decode the control channel (for example, a bandwidth, a type of control channel, and / or the like), if the UE should transmit CSI feedback associated with the monitoring of the wake-up signal and / or the CCSS resource, and / or the like. In some aspects, the control channel can be A PDCCH, a DMTC PDCCH, an NB-It PDCCH, a Legacy PDCCH, an ePDCCH, and / or the like.
[000135] In some respects, the wake-up feature can correspond to a number of
resource associated The one signal in awaken that is transmitted through in an plurality of elements in resource, and the number in elements from re course through From
which a UE is configured to monitor the wake-up signal is determined based at least in part on a maximum repetition level of control channel communications or a signal / noise ratio associated with the UE. Per
Petition 870190090687, of 12/09/2019, p. 63/117
For example, an alarm signal can be sent across multiple subframes, and an UE can monitor a portion of the multiple subframes or all subframes. In some respects, the number of subframes through which the wake-up signal is configured (for example, the length of the wake-up signal) can be based at least in part (for example, equal to) a maximum repetition level for the channel of control. In some respects, a UE configured with the maximum repetition level supported by the system can monitor all subframes. In some respects, a UE configured with a maximum control channel repetition level that is less than the maximum repetition level supported by the system can monitor less than all (for example, a portion) of the subframes. In some respects, the number of subframes and / or resource elements monitored by the UE may be a function of a maximum repetition level of the control channel associated with the UE and / or a SINR associated with the UE. In this way, the UE can conserve battery power and UE resources when in good network conditions, and can increase the probability of receiving the wake-up signal when in poor network conditions. Additionally, or alternatively, a UE can be configured to identify or monitor the wake-up feature based at least in part on the AT determination that the UE is associated with a repetition level or a signal / noise ratio that satisfies the a condition. For example, alarm signal monitoring can be enabled for A UE only when the UE is associated with poor network conditions.
[000136] In some respects, a length of the
Petition 870190090687, of 12/09/2019, p. 64/117
58/82 wake-up signal (for example, a number of resource elements, subframes, bits, and / or the like used for the wake-up signal) can be configured based, at least in part, on a maximum repetition level and / or an actual repetition level associated with the control channel, as described above. In addition, or alternatively, the length of the wake-up signal can be configured based at least in part on the fact that the wake-up signal is transmitted using transmission diversity (TxD), if the wake-up signal is transmitted using frequency hopping, a XRD cycle length associated with UE and / or cell and / or similar. For example, if the wake-up signal is transmitted using TxD, then the length of the wake-up signal (for example,
For a given RIS level) Can be configured for to be more I enjoy than if the sign of awakening not for transmitted using TxD. Similarly, if the signal in
wake-up is transmitted using frequency hopping, then the length of the wake-up signal (for example, for a given SINR level) can be configured to be shorter than if the wake-up signal is not transmitted using frequency-hopping. In this way, the length of the wake-up signal can be shorter to conserve network resources when the UE is more likely to receive the wake-up signal as a result of TxD and / or frequency hopping.
[000137] In some respects, the wake-up signal can be configured to have a longer length for a longer DRX cycle (for example, greater than or equal to a threshold), and can be configured to have a
Petition 870190090687, of 12/09/2019, p. 65/117
59/82 shorter length for a shorter DRX cycle. When the length of the DRX cycle increases, the probability of a timing and / or frequency error increases, and thus the alarm signal can be configured with a longer length to increase the probability of receiving the alarm signal by the UE. Additionally, or alternatively, the length of the wake-up signal can be explicitly configured (for example, signaled) via a radio resource control (RRC) configuration message [000138] In some respects, to reduce the time duration of the wake-up signal and enable an EU standby mode (eg micro-sleep), the wake-up signal can be transmitted using a higher bandwidth (for example, a maximum possible bandwidth or a corresponding power level maximum possible bandwidth). For example, for example, the wake-up signal can be transmitted using a complete resource block; for eMTC, the wake-up signal can be transmitted using a total of six resource blocks; and / or the like. Additionally, or alternatively, the wake-up signal can be transmitted with power boost by using power from unused resource element (s) in which the wake-up signal is transmitted, thereby decreasing the bandwidth that the UE needs to monitor. For example, for example, the wake-up signal can be transmitted in two tones, but it can use the power of the entire resource block, so that the UE would effectively achieve performance as 12 resource elements, but only monitor two
Petition 870190090687, of 12/09/2019, p. 66/117
60/82 resource elements. Additionally, or alternatively, the bandwidth used for the wake-up signal (for example, a number of resource elements in the frequency domain) can be configurable. In some respects, the wake-up signal transmission can be configured to minimize the signal by a number of symbols for transmission before reducing a number of frequencies used for transmission.
[000139] In some respects, the UE may transmit a confirmation indication (ACK) in response to the detection of the wake-up signal. In this way, the base station can conserve resources by preventing transmission on the PDCCH when an ACK is not received. In some respects, the base station can be based on the ACK for the corresponding PDCCH communication. In some respects, the base station can transmit multiple wake-up signals (for example, on an XRD duration, a paging occasion, and / or the like), and the UE can ACK the multiple wake-up signals. In some respects, if the ACK is used in response to the PDCCH communication, the base station can relay the wake-up signal and the corresponding PDCCH communication if the ACK is not received. In this case, a DRX of duration can be increased to take into account the multiple transmissions. In some respects, the UE can sleep between consecutive wake-up signals and / or corresponding PDCCH communications to achieve power savings.
[000140] In some respects, for example, an alarm signal can be sent in a different vehicle than the PDCCH communication. Additionally, or
Petition 870190090687, of 12/09/2019, p. 67/117
61/82 alternatively, a wake-up feature can correspond to multiple PDCCH carriers, subframes, search spaces, and / or the like. In some respects, the subframes used for the wake-up signal on an NB-It carrier may be the same subframes as those determined to be available for PDCCH and / or PDSCH Communications on that carrier. In some respects, a valid, independent subframe configuration (for example, a bitmap) can be flagged for the wake-up feature on the NB-It carrier. In some respects, the wake-up signal can be sent in a PDSCH region, and can occupy the entire sub-structure (for example, for independent band and / or guard band), or it can occupy only a portion of non-control subframe (for example, for band-band). Alternatively, the wake-up signal can occupy the entire sub-structure for the independent and / or guard band. In some aspects, a narrowband reference signal (NRS) may be present, and the wake-up signal may be equated and / or perforated around the NRS. In some respects, the UE can assume the presence of NRS. In some respects, the UE may assume the absence of NRS. In some respects, the UE may receive an indication of whether the NRS is present or absent in a wake-up feature (for example, the same subframe as a wake-up signal), and can decode the wake-up signal based at least partly in the statement.
[000141] Additionally, or alternatively, the UE can determine whether the NRS is present or absent in a vehicle based at least in part on the fact that the carrier
Petition 870190090687, of 12/09/2019, p. 68/117
62/82 be an anchor carrier or a non-anchor vehicle.
[000142] In some respects, the UE can apply adaptive reception diversity (Rfd) for receiving the wake-up signal and / or the corresponding PDCCH communication. For example, the UE can monitor the wake-up signal without Rdd, and can monitor the corresponding PDCCH with RxD (for example, to conserve energy when monitoring the wake-up signal). Additionally, or alternatively, the UE may modify one or more parameters to enable or disable Rdxd (for example, After a number of wake-up signals received, after a number of received PDCCH communications, after a number of paging occasions, after a number of Monitoring Occasions of PDCCH, and / or the like) based, at least in part, if a communication to be received is a wake-up signal, a corresponding PDCCH, and / or the like.
[000143] In some respects, for a bandwidth of 20 MHz, a PDCCH control region of 5 MHz can be defined in the PDSCH so that the UE can monitor a smaller bandwidth. In some respects, multiple of these legacy 5 MHz PDCCH regions can be defined. In this case, legacy PDCCH multiplexing can be reused to allow reuse of UE Hardware and / or similar.
