[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 019,679, filed on May 4, 2020, entitled “GROUP WAKE-UP SIGNALING USING SIDELINK ZONE IDENTIFIER,” and U.S. Non-Provisional Patent Application No. 17 / 211,626, filed on March 24, 2021, entitled “GROUP WAKE-UP SIGNALING USING SIDELINK ZONE IDENTIFIER,” which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for group wake-up signaling using sidelink zone identifiers. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that may support communications for multiple user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, and an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region and even global level. NR (also known as 5G) is an enhanced set of LTE mobile standards promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards (using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0007] In some aspects, a method of wireless communication performed by a base station may include: configuring a group wake-up signal based at least in part on a side link zone identifier corresponding to a geographic area; and sending the group wake-up signal to jointly wake up at least a subset of user equipment (UE) located in the geographic area corresponding to the side link zone identifier.

[0011] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a base station, may cause the one or more processors to: configure a group wake-up signal based at least in part on a side link zone identifier corresponding to a geographic area; and send a group wake-up signal to jointly wake up at least a subset of UEs located in the geographic area corresponding to the side link zone identifier.

[0012] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication.

[0026] The various aspects of the present disclosure will be described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of any other aspect of the present disclosure or combined with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method, which uses other structures, functions, or structures and functions in addition to the various aspects of the present disclosure set forth herein or uses other structures, functions, or structures and functions in addition to the various aspects of the present disclosure set forth herein to practice. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0027] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0028] It should be noted that although technical terms commonly associated with 5G or NR radio access technology (RAT) may be used herein to describe various aspects, various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0029] Figure 1 is a diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0030] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS of macro cell 102a, BS 110b may be a pico BS of pico cell 102b, and BS 110c may be a femto BS of femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0031] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0032] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay BS 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0033] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0034] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0035] UE 120 (e.g., 120a, 120b, 120c) can be dispersed in the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0036] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags that can communicate with a base station, another device (e.g., a remote device) or some other entity. A wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or provide a connection to the network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as user terminal equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component and / or a memory component). In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0037] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0038] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary for communicating with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, vehicle-to-pedestrian (V2P) protocol, vehicle-to-network (V2N) protocol, etc.), mesh network, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0039] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various classifications, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) that may span from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2) that may span from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that the terms "below 6 GHz", etc., if used herein, can broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that the terms "millimeter wave", etc., if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is expected that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0040] As indicated above, provide Figure 1 As an example. Other examples may differ from the Figure 1 as described.

[0041] Figure 2 is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0042] At the base station 110, the transmit processor 220 may receive data from the data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the (multiple) MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively.

[0043] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMOD) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data of UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some aspects, one or more components of UE 120 may be included in housing 284.

[0044] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0045] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, as well as other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 One or more antenna elements of one or more components).

[0046] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described in reference to Figure 5A-5C , Figure 6 and / or Figure 7 described).

[0047] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as described in reference to Figure 5A-5C , Figure 6 and / or Figure 7 described).

[0048] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of the base station 110 may perform one or more techniques associated with group wake-up signaling using a side link zone identifier, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of may execute or direct e.g. Figure 6 The process of 600 Figure 7 10 and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), the one or more instructions may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The operations of process 700 and / or other processes described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other examples.

[0049] In some aspects, UE 120 may include means for determining a side link zone identifier corresponding to a geographic area in which UE 120 is located, means for waking up from a sleep state based at least in part on receiving a group wake-up signal based at least in part on the side link zone identifier, etc. In some aspects, such means may include means for combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0050] In some aspects, the base station 110 may include a means for configuring a group wake-up signal based at least in part on a side link zone identifier corresponding to a geographic area, a means for sending a group wake-up signal to collectively wake up at least a subset of UEs 120 located in a geographic area corresponding to the side link zone identifier, and the like. In some aspects, such means may include a means for combining Figure 2One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0051] Although Figure 2 The blocks in the 200 and 210 are shown as distinct components, but the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0052] As indicated above, provide Figure 2 As an example. Other examples may differ from the Figure 2 as described.

[0053] Figure 3 is a diagram illustrating an example 300 of sidelink communications according to the present disclosure.

[0054] like Figure 3 As shown, the first UE 305-1 can communicate with the second UE 305-2 (and one or more other UEs 305) via one or more side link channels 310. UE 305-1 and UE 305-2 can communicate using one or more side link channels 310 for P2P communication, D2D communication, V2X communication (e.g., which can include V2V communication, V2I communication, V2P communication, V2N communication, etc.), mesh network, etc. In some aspects, UE 305 (e.g., UE 305-1 and / or UE 305-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, one or more side link channels 310 can use a PC5 interface and / or can operate in a high frequency band (e.g., a 5.9 GHz band). Additionally or alternatively, UE 305 can use global navigation satellite system (GNSS) timing to synchronize the timing of transmission time intervals (TTIs) (e.g., frames, subframes, time slots, symbols, etc.).

[0055] like Figure 3As further shown, the one or more sidelink channels 310 may include a physical sidelink control channel (PSCCH) 315, a physical sidelink shared channel (PSSCH) 320, and / or a physical sidelink feedback channel (PSFCH) 325. The PSCCH 315 may be used to communicate control information, similar to a physical downlink control channel (PDCCH) and / or a physical uplink control channel (PUCCH) used for cellular communications with the base station 110 via an access link or access channel. The PSSCH 320 may be used to communicate data, similar to a physical downlink shared channel (PDSCH) and / or a physical uplink shared channel (PUSCH) used for cellular communications with the base station 110 via an access link or access channel. For example, the PSCCH 315 may carry sidelink control information (SCI) 330, which may indicate various control information for sidelink communications, such as one or more resources (e.g., time resources, frequency resources, space resources, etc.), where a transport block (TB) 335 may be carried on the PSSCH 320. The TB 335 may include data. The PSFCH 325 may be used to communicate sidelink feedback 340 such as hybrid automatic repeat request (HARQ) feedback (eg, acknowledgement or negative acknowledgement (ACK / NACK) information), transmit power control (TPC), scheduling request (SR), and the like.

[0056] In some aspects, one or more sidelink channels 310 may use a resource pool. For example, a scheduling assignment (e.g., included in SCI 330) may be sent in a subchannel across time using specific resource blocks (RBs). In some aspects, a data transmission associated with a scheduling assignment (e.g., on PSSCH 320) may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, the scheduling assignment and the associated data transmission are not sent on adjacent RBs.

[0057] In some aspects, the UE 305 may operate using a transmission mode in which resource selection and / or scheduling is performed by the UE 305 (e.g., rather than the base station 110). In some aspects, the UE 305 may perform resource selection and / or scheduling by sensing channel availability for transmission. For example, the UE 305 may measure RSSI parameters associated with various sidelink channels (e.g., sidelink-RSSI (S-RSSI) parameters), may measure RSRP parameters associated with various sidelink channels (e.g., PSSCH-RSRP parameters), may measure RSRQ parameters associated with various sidelink channels (e.g., PSSCH-RSRQ parameters), etc., and / or may select a channel for transmission of sidelink communications based at least in part on (multiple) measurements.

[0058] Additionally or alternatively, the UE 305 may perform resource selection and / or scheduling using the SCI 330 received in the PSCCH 315, which may indicate occupied resources, channel parameters, etc. Additionally or alternatively, the UE 305 may perform resource selection and / or scheduling by determining a channel busy rate (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE 305 may use for a particular set of subframes).

[0059] In a transmission mode where resource selection and / or scheduling is performed by the UE 305, the UE 305 may generate a sidelink grant and may send the grant in the SCI 330. The sidelink grant may indicate, for example, one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks to be used for an upcoming sidelink transmission on the PSSCH 320 (e.g., for TB 335), one or more subframes to be used for an upcoming sidelink transmission, an MCS to be used for an upcoming sidelink transmission, etc. In some aspects, the UE 305 may generate a sidelink grant indicating one or more parameters for semi-persistent scheduling (SPS), such as a periodicity of the sidelink transmission. Additionally or alternatively, the UE 305 may generate a sidelink grant for event-driven scheduling, such as for an on-demand sidelink message.

[0060] As indicated above, provide Figure 3 As an example. Other examples may differ from the Figure 3 As described.

[0061] Figure 4 is a diagram illustrating an example 400 of side link communications and access link communications according to the present disclosure.

[0062] like Figure 4 As shown, the transmitter (Tx) / receiver (Rx) UE 405 and the Rx / Tx UE 410 can communicate with each other via a side link, as described above in conjunction with Figure 3 As described. Figure 4 As further shown, in some sidelink modes, the base station 110 can communicate with the Tx / Rx UE 405 via a first access link. Additionally or alternatively, in some sidelink modes, the base station 110 can communicate with the Rx / Tx UE 410 via a second access link. In some aspects, the Tx / Rx UE 405 and / or the Rx / Tx UE 410 can correspond to one or more UEs described elsewhere herein, such as Figure 1 UE 120, Figure 3UE 305, etc. Therefore, the direct link between Tx / RxUE 405 and Rx / Tx UE 410 (e.g., via a PC5 interface) can be referred to as a side link, and the direct link between the base station 110 and the Tx / Rx UE 405 and / or Rx / Tx UE 410 (e.g., via a Uu interface) can be referred to as an access link. In some aspects, the side link communication can be sent via the side link, and the access link communication can be sent via (multiple) access links. The access link communication can be a downlink communication (from the base station 110 to the Tx / Rx UE 405 or Rx / Tx UE 410) or an uplink communication (from the Tx / Rx UE 405 or Rx / Tx UE 410 to the base station 110).

[0063] In some aspects, the base station 110 and the UE 405, UE 410 may be deployed in a radio access network that utilizes millimeter wave (mmW) technology and / or directional communication (e.g., beamforming, precoding, etc.) for communication between base stations and / or UEs (e.g., between two base stations, between two UEs, and / or between a base station and a UE). In some aspects, mmW communications may be performed in FR2 including a frequency band from 24.25 GHz to 52.6 GHz. In some aspects, the wireless backhaul link between the base stations 110 may use mmW signals to carry information, and / or may use beamforming, precoding, etc. to point to the target base station 110. Similarly, the wireless access link between the UE 405, UE 410 and the base station 110 may use mmW signals and / or may be directed to a target wireless node (e.g., a UE and / or a base station). Sidelink communications between UE 405, UE 410 may be performed using mmW technology and / or beamforming, such that UE 405, UE 410 may point or otherwise direct one or more transmissions toward each other and / or receive transmissions from a particular direction by amplifying signals received at different antennas using different weighting patterns.

[0064] Therefore, as described herein, wireless communication devices (e.g., UE, base station, etc.) can use beamforming to improve radio performance, increase throughput and reliability, etc. This may be particularly useful in mmW communication systems where high operating frequencies can result in significant path loss. For example, because mmW communications have higher frequencies and shorter wavelengths than various other radio waves used for communication (e.g., communications below 6 GHz), mmW communications may have a shorter propagation distance, may suffer from atmospheric attenuation, may be more easily blocked by obstacles than other types of radio waves, and so on. Therefore, in order to improve radio performance, reduce path loss, etc., beamforming may be used to perform mmW communications, wherein a transmitting wireless communication device may generate a transmit beam, and a receiving wireless communication device may generate a corresponding receive beam. The transmit beam may be reflected, diffracted, scattered, etc. by one or more clusters, obstacles, materials, etc., between the transmitting device and the receiving device or in the surrounding environment. The term "cluster" may refer to an object in a channel environment through which energy propagates. Example clusters in mmW channel environments may include reflectors such as lamp posts, vehicles, glass / windows, metal objects, etc., diffractors such as edges or corners of buildings, walls, etc., and / or scattering via irregular objects such as walls, human bodies, etc.

[0065] Although mmW communications offer various advantages, such as improved radio performance, increased throughput, and reliability, mmW communications also present various challenges. For example, mmW relays and / or mmW sidelink communications may use a larger number of antenna elements than sub-6 GHz relays in order to support directional beams with narrower widths and therefore longer ranges (e.g., mmW beams may have beamwidths of 20 to 30 degrees (or even narrower if the UE has a large number of antenna elements), whereas beams used in sub-6 GHz relays tend to have beamwidths in the range of 90 to 120 degrees). Therefore, power consumption may become a serious problem in mmW communications, especially for UEs operating on battery power. In addition, due to the large amount of power that may be consumed by mmW communications, thermal issues may arise due to the need to dissipate power, and the UE may need to take power backoff (e.g., power management maximum power reduction (P-MPR)) when transmitting (e.g., on the uplink and / or sidelink) in order to comply with maximum permitted exposure (MPE) requirements typically established by regulatory authorities.

[0066] Therefore, because of the various challenges that arise due to the power requirements of mmW communications, UEs communicating using mmW technology may spend a significant amount of time in a sleep state (or other low power mode). However, in order to communicate using beamforming, the UE may need to know the direction of the beamforming. In some cases, the base station may indicate appropriate beamforming directions for one or more in-coverage UEs to enable discovery of other UEs, but the base station may not be able to indicate appropriate beamforming directions for out-of-coverage UEs, and / or may not have sufficient information to enable discovery between all UEs. As a result, because sidelink communications using mmW technology may rely on the ability of UEs to discover each other, UEs that are close to each other should generally wake up at the same time (or at least during overlapping times). Otherwise, if the first UE is in a sleep state and the second UE is performing a discovery operation (or vice versa), the first UE and the second UE will not be able to discover each other.

[0067] In some wireless networks, group wake-up signals can be used to wake up various UEs at the same time. For example, in some cases, group wake-up signals are sometimes used to wake up multiple UEs in eMTC, IoT and / or other applications based on UE identifiers, base station identifiers, etc. In other cases, techniques based on group wake-up signals can be configured to wake up multiple UEs with similar coverage, similar discontinuous reception (DRX) and gap configurations, or similar categories, or provide comparable services. However, these group wake-up techniques are generally not particularly suitable for mmW (or FR2) communications, where UEs in the same neighborhood (e.g., geographic area) may need to wake up at the same time in order to implement the discovery process that the UE relies on to determine the direction of beamforming. Therefore, some aspects described herein relate to techniques and devices for parameterizing group wake-up signals based on side link zone identifiers. For example, as described herein, a side link zone identifier may correspond to a geographic area, whereby the distance between side link UEs can be inferred from the corresponding side link zone identifier (e.g., UEs in different side link zones may be geographically farther apart than UEs in the same side link zone). Thus, in some aspects, the base station may configure a group wake-up signal to collectively wake up one or more UEs located in a geographic area by parameterizing the group wake-up signal according to a side link zone identifier. In this manner, the UEs located in the geographic area may wake up substantially at the same time and may then perform side link discovery operations to enable side link communications.

[0068] As indicated above, provide Figure 4 As an example. Other examples may differ from the Figure 4 as described.

[0069] Figure 5A-5C is a diagram illustrating one or more examples 500 of group wake-up signaling using a side link zone identifier according to the present disclosure. Figure 5A-5C As shown, (multiple) examples 500 include various UEs (e.g., UE1, UE2, UE3, etc., each of which may correspond to UE 120) and one or more base stations (e.g., base station 110). In some aspects, the various UEs and (multiple) base stations may be included in a wireless network such as wireless network 100. In some aspects, the UEs may communicate via a wireless side link, and the UEs may communicate with (multiple) base stations via corresponding access links.

[0070] like Figure 5A As shown, various UEs may be located in a coverage area (e.g., a cell) provided by a base station. Therefore, in some aspects, the base station may store information related to an identifier associated with each UE (e.g., a cell radio network temporary identity (C-RNTI), a service temporary mobile subscriber identity (S-TMSI), a temporary identity (TIN) used in the next update, etc.), and the base station may also know the approximate location of each UE (e.g., based on location information periodically reported by the UE, measurements associated with signals sent by the UE, etc.). In addition, in some aspects, a side link zone identifier corresponding to the geographic area in which the corresponding UE is located may be assigned to each UE. For example, in some aspects, a geographic area may be divided into continuous side link zones, and each side link zone may be of a specific size and shape. In some aspects, the side link zones may be of the same size and shape, or the size and / or shape of at least one subset of the side link zones may be different. For example, in some aspects, the dimensions of the side link zone may be defined by a side link zone configuration parameter (e.g., a radio resource control (RRC) parameter, such as an SL-ZoneConfig information element). For example, the side link zone configuration parameters may indicate the length and width of the geographical area corresponding to each side link zone, the total number of side link zones configured with respect to latitude and longitude, etc. Thus, the geographical area divided into continuous side link zones may be associated with a fixed reference point (e.g., geographical coordinates (0,0)) that may be used to determine a side link zone identifier corresponding to the corresponding geographical area in which the UE is located.

[0071] For example, in some aspects, an identifier may be assigned to each sidelink zone so that the sidelink zone may be indexed in a table, wireless communication standard, data structure, wireless communication specification, and the like. The identifier assigned to the sidelink zone may be a numbered identifier (e.g., sidelink zone 0 to sidelink zone 11), an alphabetic identifier (e.g., sidelink zone A to sidelink zone G), or other types of identifiers. In some aspects, the identifier for the sidelink zone may be defined based on an N-bit index that wraps around or repeats after a particular number of identifiers are used, such that the number of identifiers in use may be reduced while still allowing the sidelink zone to be uniquely identified within a portion of a geographic area. For example, in some aspects, the length and width of each sidelink zone, the number of sidelink zones configured with respect to latitude and longitude, a fixed reference point, and the geographic coordinates corresponding to the current location of the particular UE may be used by the UE and / or base station to determine the N-bit index (or identifier) ​​corresponding to the geographic area in which the particular UE is located based on a modulo operator. For example, in Figure 5A , UE1 and UE2 may be determined as being located in a first side link zone associated with a first side link zone identifier (e.g., zone ID 1), UE3, UE4, and UE5 may be determined as being located in a second side link zone associated with a second side link zone identifier (e.g., zone ID 2), and UE6 and UE7 may be determined as being located in a third side link zone associated with a third side link zone identifier (e.g., zone ID 3).

[0072] In some aspects, the size and shape of each side link zone can be a known and well-defined configuration, so that the use of the side link zone can allow the distance between two UEs to be determined. For example, UEs located in the same side link zone can generally be considered to be geographically close to each other, and UEs located in different side link zones can generally be considered to be geographically far apart (e.g., compared with UEs in the same side link zone). In addition or alternatively, the distance between two UEs can be inferred at least in part based on the number of side link zones between the two UEs. For example, assuming that the side link zone has a configuration with a width of 500 meters and a length of 100 meters, the maximum distance between two UEs located in the same side link zone is 500 meters. In another example, if there are two side link zones between the corresponding side link zones where the two UEs are located, then the rough approximation of the maximum distance separating the two UEs will be 2000 meters. Therefore, as described herein, the side link zone where the UE is located can provide a rough estimate of the geographical location of the UE, the geographical distance or proximity between the UEs, etc., whereby the group wake-up signal can be parameterized according to the side link zone identifier to jointly wake up at least a subset of UEs located in a specific geographic area. In this way, UEs that are collectively awakened by the group wake-up signal may perform autonomous discovery operations to discover other UEs that are geographically proximate so that the UEs may then participate in sidelink communications.

[0073] For example, Figure 5AAs shown, by reference numeral 510, the base station can parameterize one or more group wake-up signals according to the side link zone identifier so as to jointly wake up at least a subset of UEs located in a geographic area corresponding to a specific side link zone identifier. For example, in some aspects, the UE can enter a sleep state or other low-power state to save battery resources, processor resources, radio resources, etc., and the UE can include a specific module or subsystem, referred to herein as a wake-up receiver, to detect the group wake-up signal. When the wake-up receiver detects a group wake-up signal parameterized according to the side link zone identifier corresponding to the geographic area where the UE is located, the modem and / or the entire communication chain (e.g., any combination of antenna 252, MOD254, MIMO detector 256, receiving processor 258, controller / processor 280, etc.) can enter an active state to receive control channels and subsequent shared channels. For example, in some aspects, the group wake-up signal can be an analog waveform, such as a tone based on on-off keying (OOK) generated according to one or more parameters, a preamble, a reference signal, etc. Therefore, as described herein, one or more parameters for generating a group wake-up signal may include at least one side link zone identifier, whereby the parameter set associated with the group wake-up signal may be an explicit and / or implicit function of the side link zone identifier. In this way, all UEs located in a geographic area corresponding to a specific side link zone identifier may have the same wake-up signal parameters, and different side link zone identifiers may be associated with different wake-up signal parameters. In other words, a group wake-up signal parameterized according to a specific side link zone identifier may wake up at least a subset of UEs in the corresponding side link zone. In addition, in some aspects, the group wake-up signal may not wake up one or more UEs located in different side link zones.

[0074] Thus, in some aspects, the base station may determine a sidelink zone identifier associated with a subset of UEs to be awakened, and may generate a group wake-up signal including a wake-up signal parameter configuration as an explicit or implicit function of the sidelink zone identifier. Figure 5AAs shown, the base station may generate and send a first group wake-up signal (WUS1) to collectively wake up at least a subset of UEs located in a geographic area corresponding to a first side link zone identifier (e.g., zone ID 1), may generate and send a second group wake-up signal (WUS2) to collectively wake up at least a subset of UEs located in a geographic area corresponding to a second side link zone identifier (e.g., zone ID 2), may generate and send a third group wake-up signal (WUS3) to collectively wake up at least a subset of UEs located in a geographic area corresponding to a third side link zone identifier (e.g., zone ID 3), etc. Thus, while in a sleep state or other low power state, the UE may monitor an access link (e.g., PDCCH) for a group wake-up signal parameterized at least in part based on a side link zone identifier corresponding to the geographic area in which the UE is located, and may wake up or otherwise transition to an active state based at least in part on detecting such a group wake-up signal. In addition, in mmW communications, the base station can perform beam scanning on the group wake-up signal on multiple wake-up beams directionally directed to the geographic area corresponding to the side link zone identifier, thereby improving the spatial and temporal diversity of the wake-up signal, reducing the possibility of detection failure due to beam degradation, saving resources by avoiding sending the group wake-up signal in a direction away from the geographic area of ​​the UE to be awakened, and so on.

[0075] In some aspects, as described above, the UE may generally monitor the access link for a group wake-up signal parameterized at least in part based on a side link zone identifier corresponding to the geographic area where the UE is located. In addition, in some aspects, the UE may additionally monitor the access link for a group wake-up signal parameterized according to (multiple) identifiers associated with one or more adjacent side link zones. For example, when the UE changes its geographic location, the mobile UE may move between different side link zones, whereby the UE may monitor the group wake-up signal parameterized according to (multiple) identifiers associated with the adjacent side link zone, and in the case of potential and / or possible movement to the adjacent side link zone, the UE can be ensured to wake up at the same time as the UE in the adjacent side link zone. In addition, in some cases, one or more adjacent side link zones may be located in the same cell as the serving base station, in an adjacent cell, etc., whereby monitoring the group wake-up signal associated with the adjacent side link zone can facilitate potential and / or possible switching from the serving base station to the adjacent base station. In some aspects, the base station may indicate the adjacent side link zone identifier to be monitored by a specific UE, and different base stations may communicate via the backhaul to determine the adjacent side link zone to be monitored across different cells. Additionally, in some aspects, the UE may continue to monitor the group wake-up signal associated with the side link zone that the UE was previously located in for a period of time after changing the side link zone. In this way, when the UE changes position again and moves back to the previous side link zone, the continued monitoring of the group wake-up signal associated with the previous side link zone can provide a hysteresis function.

[0076] In some aspects, such as Figure 5B As shown by reference numeral 520, the geographic area corresponding to a particular sidelink zone may span multiple cells. For example, in some aspects, the sidelink zone identifiers may be grouped together across multiple cells so that UEs that are geographically close may have the same group wake-up signal parameters even though they are located in different cells. Figure 5B As shown, the geographical area corresponding to the sidelink zone with the identifier "zone ID 2" includes a first portion located in a first cell provided by a first base station and a second portion located in a second cell provided by a second base station. Therefore, by aggregating sidelink zones across multiple cells provided by different base stations, geographically adjacent UEs can be woken up together at the same time. For example, Figure 5B As shown, the base stations in the neighboring cells can each send a PDCCH including a group wake-up signal parameterized according to the sidelink zone identifier "zone ID 2" to jointly wake up all (or a subset) of the UEs located in the corresponding geographical area. Figure 5B, the first base station (gNB1) can send a group wake-up signal (WUS2) to jointly wake up UE3, UE4 and UE5 located in the cell provided by the first base station, and the second base station (gNB2) can send the same group wake-up signal to jointly wake up UE8 and UE9 located in the cell provided by the second base station. In this way, by aggregating sidelink zones across different cells, UEs can be more easily monitored in a wider geographical area, which can facilitate switching across different base stations, TRPs, etc. In addition, in some aspects, base stations in adjacent cells can communicate (e.g., via a backhaul) to configure a geographical area corresponding to a sidelink zone spanning multiple cells. For example, in some aspects, adjacent base stations can exchange information related to network-level statistical metrics to determine an appropriate geographical configuration for a particular sidelink zone aggregated across different cells, the network-level statistical metrics being related to the geographical proximity between UEs located within the respective cells.

[0077] In some aspects, such as Figure 5C As shown, the group wake-up signal can be configured to wake up or otherwise activate a subset of links within a geographic area corresponding to a particular side link zone identifier. For example, as shown by reference numeral 530, the group wake-up signal can activate all access links (e.g., Uu links between a base station and UEs) for a subset of UEs that are woken up together within the geographic area. In addition, as shown by reference numeral 535, the group wake-up signal can activate a subset of side links (e.g., PC5 links between UEs) for a subset of UEs that are woken up together within the geographic area. For example, in Figure 5C In , the group wake-up signals of "zone ID 1" and "zone ID 3" wake up all access links and all side links in the corresponding side link zone (e.g., the subset of the side links awakened includes all side links in the corresponding side link zone), but the group wake-up signal of "zone ID 2" wakes up only a portion of the side links in the corresponding side link zone. Figure 5C In the example, the group wake-up signal of "zone ID 2" does not activate the side link between UE5 and UE3 (e.g., because the distance between UE5 and UE3 meets the threshold). In some aspects, the base station can determine the subset of side links to be woken up or otherwise activated based on network-level statistical metrics (e.g., distances between UEs, knowledge about which UEs are or are not involved in side link sessions, etc.).

[0078] As indicated above, provide Figure 5A-5C As one or more examples. Other examples may differ from the Figure 5A-5C as described.

[0079] Figure 66 is a diagram illustrating an example process 600, performed, for example, by a base station, according to the present disclosure. Example process 600 is an example of a base station (eg, base station 110, etc.) performing operations associated with group wake-up signaling using a sidelink zone identifier.

[0080] like Figure 6 As shown, in some aspects, process 600 may include configuring a group wake-up signal based at least in part on a side link zone identifier corresponding to a geographic area (block 610). For example, a base station may configure (e.g., using transmit processor 220, receive processor 238, controller / processor 240, memory 242, etc.) a group wake-up signal based at least in part on a side link zone identifier corresponding to a geographic area, as described above.

[0081] like Figure 6 As further shown, in some aspects, process 600 may include sending a group wake-up signal to collectively wake up at least a subset of UEs located in a geographic area corresponding to the sidelink zone identifier (block 620). For example, the base station may send (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, memory 242, etc.) a group wake-up signal to collectively wake up at least a subset of UEs located in a geographic area corresponding to the sidelink zone identifier, as described above.

[0082] Process 600 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0083] In a first aspect, a group wake-up signal is associated with a parameter configuration based at least in part on a side link zone identifier.

[0084] In a second aspect, either alone or in combination with the first aspect, the parameters are configured such that the group wake-up signal collectively wakes up a subset of UEs located in a geographic area corresponding to the side link zone identifier, without waking up one or more UEs located outside the geographic area corresponding to the side link zone identifier.

[0085] In a third aspect, alone or in combination with one or more of the first and second aspects, at least a portion of the geographic area corresponding to the sidelink zone identifier is located in a neighboring cell.

[0086] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, process 600 includes communicating with a base station providing a neighboring cell to configure a geographic area corresponding to a side link zone identifier based at least in part on one or more statistical metrics related to geographic proximity between UEs.

[0087] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 600 includes sending information indicating one or more adjacent side link zone identifiers to one or more UEs located in a geographic area corresponding to a side link zone identifier, wherein the one or more UEs listen for a group wake-up signal associated with the side link zone identifier corresponding to the geographic area where the one or more UEs are located, and listen for a group wake-up signal associated with one or more adjacent side link zone identifiers.

[0088] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, a group wake-up signal activates an access link and at least a subset of the side links for each UE located in a geographic area corresponding to the side link zone identifier.

[0089] In a seventh aspect, either alone or in combination with one or more of aspects 1 to 6, process 600 includes determining, based at least in part on one or more network-level statistical metrics, a subset of side links to be activated for each UE located in a geographic area corresponding to a side link zone identifier.

[0092] like Figure 7 As shown, in some aspects, process 700 may include determining a sidelink zone identifier corresponding to a geographic region in which the UE is located (block 710). For example, the user equipment may determine (e.g., using controller / processor 280, memory 282, etc.) a sidelink zone identifier corresponding to a geographic region in which the UE is located, as described above.

[0093] like Figure 7As further shown, in some aspects, process 700 may include waking up from a sleep state based at least in part on receiving a group wake-up signal based at least in part on the sidelink zone identifier, wherein the group wake-up signal is configured to collectively wake up at least a subset of UEs located in a geographic area corresponding to the sidelink zone identifier (block 720).

[0095] In a first aspect, a group wake-up signal is associated with a parameter configuration based at least in part on a side link zone identifier.

[0096] In a second aspect, either alone or in combination with the first aspect, the parameters are configured such that the group wake-up signal collectively wakes up a subset of UEs located in a geographic area corresponding to the side link zone identifier, without waking up one or more UEs located outside the geographic area corresponding to the side link zone identifier.

[0097] In a third aspect, alone or in combination with one or more of the first and second aspects, at least a portion of the geographic area corresponding to the sidelink zone identifier is located in a neighboring cell.

[0098] In a fourth aspect, alone or in combination with one or more of the first to third aspects, process 700 includes receiving information indicating one or more adjacent side link zone identifiers from a base station, and monitoring for a group wake-up signal associated with a side link zone identifier corresponding to a geographic area in which the UE is located, and monitoring for a group wake-up signal associated with one or more adjacent side link zone identifiers.

[0101] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the group wake-up signal activates an access link for the UE and activates at least a subset of the side link for the UE.

[0102] although Figure 7 Example blocks of process 700 are shown, but in some aspects, Figure 7 Process 700 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in FIG. Additionally or alternatively, two or more of the blocks of process 700 may be performed in parallel.
