Abstract

Various aspects of the present disclosure generally relate to signaling for channel occupancy time (COT) sharing in a frame-based equipment (FBE) mode. In some aspects, a user equipment (UE) may receive a message associated with a designation of the UE for COT sharing or non-COT sharing in association with the FBE mode. The UE may detect the presence of an initial signal at a boundary of a time frame for COT and sleep, monitor, or communicate during the time frame based at least in part on the designation and the detection. Numerous other aspects are provided.

Description

[0001] Public domain

[0002] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for signaling of channel occupancy time sharing in a frame-based equipment mode.

[0003] background

[0004] Wireless communication systems are widely deployed to provide various 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 communication network may include several base stations (BS) that can support communication of several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the 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, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by 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 referred to 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 to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0007] Overview

[0008] In some aspects, a wireless communication method performed by a user equipment (UE) may include: receiving a message associated with a designation of the UE for channel occupancy time (COT) sharing or non-COT sharing in association with a frame-based equipment (FBE) mode. The method may include detecting whether an initial signal exists at a boundary of a time frame for the COT. The method may include performing one or more of sleeping, monitoring, or communicating during the time frame based at least in part on the designation and the detection.

[0009] In some aspects, a wireless communication method performed by a device may include determining, based at least in part on one or more parameters associated with communications conducted by another device, a designation of the other device for COT sharing or non-COT sharing in FBE mode. The method may include performing an action based at least in part on the designation.

[0010] In some aspects, a UE for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: receive a message associated with a designation of the UE for COT sharing or non-COT sharing in association with an FBE mode. The memory and the one or more processors may detect whether an initial signal is present at a boundary of a time frame for COT, and perform one or more of sleeping, monitoring, or communicating during the time frame based at least in part on the designation and the detection.

[0011] In some aspects, a device for wireless communication, such as a base station, may include a memory and one or more processors operatively coupled to the memory.

[0012] 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 UE, may cause the one or more processors to: receive a message associated with a designation of the UE for COT sharing or non-COT sharing in association with an FBE mode. The one or more instructions, when executed by one or more processors of the UE, may cause the one or more processors to: detect whether an initial signal is present at a boundary of a time frame for COT, and perform one or more of sleeping, monitoring, or communicating during the time frame based at least in part on the designation and the detection.

[0013] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication.

[0014] In some aspects, an apparatus for wireless communication may include: a device for receiving, in association with an FBE mode, a message associated with a designation of the apparatus for COT sharing or non-COT sharing; a device for detecting whether an initial signal is present at a boundary of a time frame for COT; and a device for performing one or more of sleeping, monitoring, or communicating during the time frame based at least in part on the designation and the detection.

[0031] Detailed Description

[0032] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination 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 devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0033] 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.

[0034] It should be noted that although various aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0035] Figure 11 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BSs 110a, BSs 110b, BSs 110c, and BSs 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NRBS, B node, gNB, 5G B node (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular 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.

[0036] 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., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by 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 for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0037] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections, virtual networks, and / or the like using any suitable transport network.

[0038] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data 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 , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0039] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, 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).

[0040] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0041] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may 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, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / 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.

[0042] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular 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 client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, and the like.

[0043] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may 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 may be deployed.

[0044] 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 to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0045] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0046] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1One for each base station and one for each UE in the base station 110. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0047] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, 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 each UE based at least in part on the MCS selected for the 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), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), 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)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The 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, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) 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. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0048] 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 (DEMODs) 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, etc.) 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 where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0049] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). 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, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 as well as 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 sent by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and provide decoded control information to a 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 network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0050] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the may perform one or more techniques associated with signaling for COT sharing in FBE mode, 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 of the Fig. 9 The process of 900 Fig.10 1000, and / or operations of other processes as 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 for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120, may perform or direct, for example, Fig. 9 The process of 900 Fig.10 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0051] In some aspects, UE 120 may include: means for receiving, in association with a frame-based equipment mode, a message associated with a designation of the UE for COT sharing or non-COT sharing; means for detecting the presence of an initial signal at a boundary of a time frame for COT; means for performing one or more of sleeping, monitoring, or communicating during the time frame based at least in part on the designation and the detection; and the like. In some aspects, such means may include in conjunction with 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, and the like.

[0052] In some aspects, base station 110 may include: means for determining, based at least in part on one or more parameters associated with communications conducted by another device, a designation of the other device for COT sharing or non-COT sharing in FBE mode; means for performing an action based at least in part on the designation; and the like. In some aspects, such means may include in conjunction with Figure 2 One 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.

[0053] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0054] Figure 3A An example frame structure 300 for frequency division duplex (FDD) in a telecommunication system (e.g., NR) is shown. The transmission timeline for each of the downlink and uplink may be divided into units of radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z ≥ 1) subframes (e.g., with indices 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., in Figure 3A Each subframe 2 is shown m time slots, where m is a parameter design for transmission, such as 0, 1, 2, 3, 4, etc.). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3A ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two slots (e.g., when m=1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices 0 to 2L–1. In some aspects, the scheduling unit for FDD may be frame-based, subframe-based, slot-based, symbol-based, etc.

[0055] Although some techniques are described herein in conjunction with frames, subframes, time slots, etc., these techniques may be equally applicable to other types of wireless communication structures that may be referred to in 5G NR using terms other than "frames," "subframes," "time slots," etc. In some aspects, a wireless communication structure may refer to a periodic, time-bounded communication unit defined by a wireless communication standard and / or protocol. Additionally or alternatively, a wireless communication structure may be used in conjunction with Figure 3A The wireless communication structure configurations are different from those shown in FIG.

[0056] In some telecommunications (e.g., NR), a base station may transmit a synchronization (SYNC) signal. For example, a base station may transmit a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and the like on the downlink for each cell supported by the base station. The PSS and SSS may be used by the UE for cell search and acquisition. For example, the PSS may be used by the UE to determine symbol timing, and the SSS may be used by the UE to determine a physical cell identifier associated with the base station and frame timing. The base station may also transmit a physical broadcast channel (PBCH). The PBCH may carry some system information, such as system information that supports initial access of the UE.

[0057] In some aspects, a base station may transmit a PSS, SSS, and / or PBCH according to a synchronization communication level (e.g., a synchronization signal (SS) level) including multiple synchronization communications (e.g., SS blocks), as described below in conjunction with Figure 3B As described.

[0058] Figure 3B is a block diagram conceptually illustrating an example SS hierarchy, which is an example of a synchronous communication hierarchy. Figure 3B As shown in FIG. 1 , the SS hierarchy may include an SS burst set, which may include a plurality of SS bursts (identified as SS burst 0 to SS burst B-1, where B is the maximum number of repetitions of the SS burst that may be transmitted by the base station). As further shown, each SS burst may include one or more SS blocks (identified as SS block 0 to SS block (b max_SS-1 ), where b max_SS-1 is the maximum number of SS blocks that can be carried by an SS burst. In some aspects, different SS blocks may be beamformed differently. A set of SS bursts may be transmitted by a wireless node periodically, such as every X milliseconds, e.g. Figure 3B In some aspects, SS burst sets may have fixed or dynamic lengths, such as in Figure 3B is shown as Y milliseconds.

[0059] Figure 3B The SS burst set shown in is an example of a synchronous communication set, and other synchronous communication sets may be used in conjunction with the techniques described herein. Figure 3B The SS blocks shown in are examples of synchronous communications, and other synchronous communications may be used in conjunction with the techniques described herein.

[0060] In some aspects, an SS block includes resources that carry PSS, SSS, PBCH, and / or other synchronization signals (e.g., a third synchronization signal (TSS)) and / or synchronization channels. In some aspects, multiple SS blocks are included in an SS burst, and the PSS, SSS, and / or PBCH may be identical for each SS block across an SS burst. In some aspects, a single SS block may be included in an SS burst. In some aspects, an SS block may be at least four symbol periods in length, with each symbol carrying one or more of a PSS (e.g., occupying one symbol), an SSS (e.g., occupying one symbol), and / or a PBCH (e.g., occupying two symbols).

[0061] In some aspects, the symbols of the SS block are consecutive, such as Figure 3BIn some aspects, the symbols of the SS block are non-contiguous. Similarly, in some aspects, one or more SS blocks of an SS burst may be transmitted in contiguous radio resources (e.g., contiguous symbol periods) during one or more time slots. Additionally or alternatively, one or more SS blocks of an SS burst may be transmitted in non-contiguous radio resources.

[0062] In some aspects, an SS burst may have a burst periodicity, whereby each SS block of the SS burst is transmitted by the base station according to the burst periodicity. In other words, the SS blocks may be repeated during each SS burst. In some aspects, an SS burst set may have a burst set periodicity, whereby each SS burst of the SS burst set is transmitted by the base station according to a fixed burst set periodicity. In other words, the SS burst may be repeated during each SS burst set.

[0063] The base station may transmit system information, such as system information blocks (SIBs), on a physical downlink shared channel (PDSCH) in certain time slots. The base station may transmit control information / data on a physical downlink control channel (PDCCH) in C symbol periods of a time slot, where B may be configurable for each time slot. The base station may transmit traffic data and / or other data on the PDSCH in the remaining symbol periods of each time slot.

[0064] As indicated above, Figure 3A and 3B are provided as examples. Other examples may differ from those described in Figure 3A and 3B Examples described.

[0065] Figure 4 An example slot format 410 with a normal cyclic prefix is ​​shown. Available time-frequency resources may be divided into resource blocks. Each resource block may cover a set of subcarriers (e.g., 12 subcarriers) in one slot and may include several resource elements. Each resource element may cover one subcarrier in one symbol period (e.g., in time) and may be used to send one modulation symbol, which may be a real value or a complex value.

[0066] For FDD in certain telecommunication systems (e.g., NR), an interleaving structure may be used for each of the downlink and uplink. For example, Q interleavings with indices 0 to Q–1 may be defined, where Q may be equal to 4, 6, 8, 10, or some other value. Each interleaving may include time slots spaced apart by Q frames. Specifically, interleaving q may include time slots q, q+Q, q+2Q, etc., where q∈{0,…,Q–1}.

[0067] The UE may be located within the coverage of multiple BSs. One of these BSs may be selected to serve the UE. The serving BS may be selected based at least in part on various criteria such as received signal strength, received signal quality, path loss, etc. The received signal quality may be quantified by a signal-to-noise-and-interference ratio (SNIR), or a reference signal received quality (RSRQ), or some other metric. The UE may operate in a strong interference scenario, in which the UE may observe high interference from one or more interfering BSs.

[0068] Although aspects of the examples described herein may be associated with NR or 5G technology, aspects of the present disclosure may be applicable to other wireless communication systems. A new radio (NR) may refer to a radio configured to operate according to a new air interface (e.g., an air interface different from an orthogonal frequency division multiple access (OFDMA)-based air interface) or a fixed transport layer (e.g., different from an Internet Protocol (IP)). In various aspects, NR may utilize OFDM with CP (referred to herein as cyclic prefix OFDM or CP-OFDM) and / or SC-FDM on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using time division duplex (TDD). In various aspects, NR may, for example, utilize OFDM with CP (referred to herein as CP-OFDM) and / or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include enhanced mobile broadband (eMBB) services targeting wide bandwidth (e.g., 80 megahertz (MHz) and above), millimeter wave (mmW) targeting high carrier frequencies (e.g., 60 gigahertz (GHz)), massive MTC (mMTC) targeting non-backward compatible MTC technologies, and / or mission critical services targeting ultra-reliable low latency communications (URLLC) services.

[0069] In some aspects, a single component carrier bandwidth of 100 MHz may be supported. NR resource blocks may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) over a duration of 0.1 milliseconds (ms). Each radio frame may include 40 slots and may have a length of 10 ms. Thus, each slot may have a length of 0.25 ms. Each slot may indicate a link direction (e.g., DL or UL) for data transmission and the link direction for each slot may be switched dynamically. Each slot may include DL / UL data and DL / UL control data.

[0070] Beamforming may be supported and the beam direction may be dynamically configured. MIMO transmission with precoding may also be supported. MIMO configuration in DL may support up to 8 transmit antennas (multi-layer DL transmission with up to 8 streams) and up to 2 streams per UE. Multi-layer transmission with up to 2 streams per UE may be supported. Aggregation of multiple cells may be supported using up to 8 serving cells. Alternatively, NR may support different air interfaces other than OFDM-based interfaces. NR networks may include entities such as central units or distributed units.

[0071] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 Examples described.

[0072] A wireless network may operate on one or more frequencies, which may also be referred to as carriers or frequency channels. Some carriers used for wireless communications are licensed carriers. Cellular networks, such as LTE networks or 5G networks, may use licensed carriers. Wireless local area networks or Wi-Fi networks may use unlicensed carriers. 5G networks may utilize licensed assisted access (LAA), which utilizes unlicensed carriers in combination with licensed carriers to improve the performance of UEs.

[0073] Transmissions on unlicensed carriers may require the transmitting device (such as a UE) to determine whether the carrier (frequency channel) is clear for transmission. Listen before talk (or listen before transmit) (LBT) is a mechanism whereby a device should apply a clear channel assessment (CCA) check (i.e., perform spectrum sensing for a certain period of time, referred to as the CCA period) before using a channel. CCA uses energy detection (ED) to detect the presence (channel is busy) or absence (channel is clear) of other signals on the channel. If the energy detected during the initial CCA period is below a certain threshold (ED threshold), the device can access the channel for a period of time referred to as the channel occupancy time (COT). Otherwise, an extended CCA period begins, in which the detected energy is again compared to the ED threshold until channel access is granted.

[0074] COT sharing is a mechanism where one device uses one LBT to acquire a COT and another device uses another LBT to share the COT. The duration of the COT may be limited by a maximum COT limit. The purpose of COT sharing is to allow privileges for LAA uplinks, where one device (e.g., an eNB) can send a grant to another device (e.g., a UE) before the UE can transmit uplink communications.

[0075] COT sharing may involve two devices sharing a time resource, such as a frame in a frame-based equipment (FBE) mode. Although the FBE mode involves an unlicensed band, the FBE mode may have a fixed frame period rather than being demand-driven. A device in FBE mode may perform CCA using ED during the channel observation time. If the channel is clear, the device may transmit using COT without re-evaluating the channel during this COT. The device may perform a new CCA for the next frame. If the channel is not clear, the device may remain silent in the next frame. The device may perform a CCA once per frame, and the channel access opportunity may be once per frame.

[0076] COT sharing may be used for transmissions from a UE to a base station (e.g., a gNB). In FBE mode, without COT sharing, if the UE does not detect an initial signal at a frame boundary, the UE is able to sleep until the next frame. In the case of COT sharing, the UE may not be able to go to sleep at all. For example, in the case of UE-to-gNB COT sharing, the UE may be awake to share a frame of the COT with the gNB. In the case of gNB-to-gNB COT sharing, if one gNB fails LBT at a frame boundary, the gNB may join the frame of another gNB (with single-slot LBT). In the case of gNB-to-gNB COT sharing, a non-shared UE may need to monitor downlink control signals and broadcast signals. In other words, if COT sharing is not suitable for the UE (e.g., no low latency requirements, no high data throughput), the UE may not be aware of this and may otherwise remain awake to monitor signals or frames expecting a shared COT. In the context of COT sharing in FBE mode, the UE may waste power as well as processing and signaling resources by missing sleep opportunities.

[0077] According to various aspects described herein, a base station can indicate information about COT sharing to a UE so that the UE has more information to determine when to go to sleep, when to monitor a signal, or when to communicate with the base station. In this way, the UE can take advantage of sleep opportunities and spend less time on activities that consume power and processing and signaling resources.

[0078] In some aspects, the base station may divide UEs into two categories based on parameters such as quality of service (QoS) requirements. For UEs requiring high QoS (high QoS is important for transmissions with low latency requirements or high data rates, or for transmissions of certain services), the base station may designate these UEs as belonging to a first category for COT sharing. The remaining UEs may form a second category, in which there is no COT sharing. UEs in the second category may sleep more and save power.

[0079] Figure 5is a diagram illustrating an example 500 of signaling for COT sharing in FBE mode in accordance with various aspects of the present disclosure. Figure 5 5 shows a method that can be used with a UE 520 (e.g., Figure 1 and 2 120) communicating with a BS 510 (e.g., Figure 1 and 2 BS110 depicted in FIG.

[0080] As indicated by reference numeral 530, BS 510 may determine a designation of another device (e.g., UE, gNB) for COT sharing or non-COT sharing in FBE mode based at least in part on one or more parameters associated with communications conducted by the other device. These parameters may include QoS requirements, latency requirements, data volume, service type, etc.

[0081] In some aspects, UEs in the first category may not have any control information or data associated with different types of COT sharing. For UEs in the first category in FBE mode, if the UE does not detect an initial signal at a frame boundary (one or more start detection opportunities of the frame), the UE may enter a sleep mode within the COT time (such as a transmission time frame) until the next frame. In this case, the UE may save power.

[0082] In some aspects, it may be expected that UEs in the second category receive some control information or data about different types of COT sharing. The UE may receive a designation of COT sharing and receive an indication of the type of COT sharing through a radio resource control (RRC) configuration message or a downlink control information (DCI) message. For example, type 0 is a type of COT sharing that may include UE-to-gNB COT sharing. For type 0 COT sharing, the UE 520 may need to monitor downlink control signals and broadcast signals. The UE 520 may monitor downlink control signals and broadcast signals with a limited number of symbols. For example, the UE 520 may monitor fewer symbols, such as 2 symbols for a subcarrier spacing (SSC) of 15 kHz, 4 symbols for an SCS of 30 kHz, and 8 symbols for an SCS of 60 kHz. Type 1 COT sharing may include TRP-to-TRP COT sharing, or gNB-to-gNB COT sharing. Type 2 COT sharing may include both type 0 and type 1 COT sharing.

[0083] As indicated by reference numeral 535, BS 510 may transmit a message indicating the designation and the COT sharing type to UE 520. For example, the designation may be for COT sharing, and the COT sharing type may be type 0 (e.g., UE to gNB COT sharing). In this example, UE 520 may enter sleep, monitor signals, or communicate with BS 510 based at least in part on the message received by UE 520 or the signal detected by UE 520.

[0084] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described in Figure 5 Examples described.

[0085] Figure 6 An example 600 of signaling for COT sharing in FBE mode is illustrated in accordance with various aspects of the present disclosure. Figure 6 Shown is a BS 610 (eg, BS 110, BS 510) that may communicate with a UE 620 (eg, UE 120, UE 520). The BS 610 and UE 620 may be in FBE mode, and the communication may be frame-based.

[0086] In some aspects, the UE 620 may monitor signals on the frequency band and act based at least in part on information regarding COT sharing received by the UE 620 from the BS 610. For example, the information may indicate UE-to-gNB COT sharing (e.g., Type 0) for the UE 620. As shown by reference numeral 630, the UE 620 may detect, as part of an LBT procedure, whether an initial signal is present at a boundary of a time frame 635 for the COT shared between the BS 610 and the UE 620. The initial signal may be at the beginning of the frame 635, such as an LBT / CCA period, a first detection opportunity, a second detection opportunity, etc.

[0087] As shown by reference numeral 640, UE 620 may share a frame 635 of the COT with BS 610. BS 610 may transmit or receive communications in frame 635. Some of these communications may be with UE 620 or with other devices. UE 620 may transmit or receive communications in frame 635. Some of these communications may be with BS 610 or with other devices. Frame 635 shows, for example, that BS 610 transmits a downlink message, a guard time, and then UE 620 transmits an uplink message.

[0088] In some aspects, if the UE 620 receives a designation for non-COT sharing, the UE 620 may detect whether there is an initial signal at the boundary of the frame 635. If the UE 620 does not detect a signal, the UE 620 may enter a sleep mode for the frame 635. If the UE 620 is designated for COT sharing, the UE 620 may remain awake during the 635 frame to transmit or receive communications.

[0089] As indicated above, Figure 6 are provided as examples. Other examples may differ from those described in Figure 6 Examples described.

[0090] Figure 7 An example 700 of signaling for COT sharing in FBE mode is illustrated in accordance with various aspects of the present disclosure. Figure 7 A BS 710 (e.g., BS 110, BS 510) is shown that can communicate with a UE 720 (e.g., UE 120, UE 520) and with another BS 730 (e.g., BS 110, BS 510). BS 710, UE 720, and UE 730 can be in FBE mode and the communication can be frame-based.

[0091] In some aspects, the COT sharing type may be gNB-to-gNB COT sharing (e.g., Type 1). As indicated by reference numeral 740, UE 720 may be a non-shared node that monitors control signals and broadcast signals based at least in part on receiving an indication of the COT type. As indicated by reference numeral 745, BS 710 may perform an LBT procedure. If the LBT procedure is unsuccessful and the channel is not clear, BS 710 may share frames of the COT with BS 730, as indicated by reference numeral 750.

[0092] In some aspects, to save power, the UE 720 may detect control signaling at predefined occasions in the time domain and sleep at the rest of the time duration. The UE 720 may be more efficient during gNB-to-gNB COT sharing.

[0093] As indicated above, Figure 7 are provided as examples. Other examples may differ from those described in Figure 7 Examples described.

[0094] Figure 8 An example 800 of possible detection opportunities in a frame of a COT in accordance with various aspects of the present disclosure is illustrated.

[0095] In some aspects, multiple UEs may be configured with a time pattern for opportunities during a frame at which the UEs may monitor and detect control signals and broadcast signals. For example, UE0 may have detection opportunities throughout the frame. This may be because UE0 is involved in the transmission of a large amount of data or a transmission with low latency requirements. If UE0 is involved in a high throughput service, a low latency service, or both, UE0 may need more detection opportunities.

[0096] In some aspects, the base station can reduce or minimize the duration of the UE's temporal pattern to allow for longer sleep times. For example, UE1 can monitor the first few detection opportunities, and if no control signal or broadcast signal is received indicating that other signals may be forthcoming, UE1 can enter sleep mode for the remainder of the frame. In some aspects, the base station can configure the UE to monitor for signals at detection opportunities located in different parts of the frame. Figure 8 As shown, UE1 may monitor the signal at the first few detection occasions, UE2 may monitor the signal at the first few detection occasions after the first few detection occasions, and UE3 may monitor the signal at the later few detection occasions. In some aspects, the UE may receive the time pattern via an RRC or DCI message. In this way, UEs with less COT sharing requirements may be provided with more certainty that they may not participate in COT sharing, thereby allowing more sleep. In this way, as described above in conjunction with Figure 5-8 As described, a UE in FBE mode having information shared about the COT can be configured to have more opportunities to sleep in time, including during frames of the COT. The UE can save power as well as processing and signaling resources.

[0097] Fig. 9 900 is a diagram illustrating an example process 900 performed, for example, by a UE according to various aspects of the present disclosure. The example process 900 is a diagram in which a UE (e.g., Figure 1 and 2 UE 120 depicted in Figure 5 An example of UE 520, etc. depicted in FIG. 5 ) performing operations associated with signaling for COT sharing in FBE mode.

[0098] like Fig. 9 As shown in , in some aspects, process 900 may include receiving a message associated with a designation of the UE for COT sharing or non-COT sharing in association with a frame-based equipment mode (block 910). For example, the UE (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, etc.) may receive a message associated with a designation of the UE for COT sharing or non-COT sharing in association with a frame-based equipment mode, as described above.

[0099] like Fig. 9 As further shown in FIG. 9 , in some aspects, process 900 may include detecting whether an initial signal is present at a boundary of a time frame for COT (block 920).

Additionally or alternatively, two or more blocks of the process 900 may be executed in parallel.

The example process 1000 is a diagram in which a device (e.g., Figure 1 and 2 BS110 depicted in Figure 5 An example of BS 510, etc. depicted in FIG. 5A ) performing operations associated with signaling for COT sharing in FBE mode.
