[0002] This patent application claims priority to U.S. Patent Application No. 17 / 811,468, filed on July 8, 2022, entitled “SIDELINK RESOURCES BASED ON INTERFERENCE CANCELATION CAPABILITY” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of this patent application and is incorporated into this patent application by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for using sidelink resources based on interference cancellation capabilities. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephone, 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 one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. The new radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, 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. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0033] The various aspects of the present disclosure are 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. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be appreciated 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 it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may 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 implemented using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0034] 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 may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0035] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0036] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e). The wireless network 100 may also include one or more network entities, such as a base station 110 (shown as BS110a, BS110b, BS110c, and BS110d) and / or other network entities. The base station 110 is a network entity that communicates with the UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a B node, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit receive point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0037] The base station 110 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 by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. In Figure 1 In the example shown in , BS 110a may be a macro base station for macro cell 102a, BS 110b may be a pico base station for pico cell 102b, and BS 110c may be a femto base station for femto cell 102c. A base station may support one or more (eg, three) cells.

[0038] In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected with each other and / or to one or more other base stations 110 or network entities in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0039] In some aspects, the term "base station" (e.g., base station 110) or "network entity" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station" or "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network entity" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with base station 110). In some aspects, the term "base station" or "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network entity" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network entity" may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network entity" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.

[0040] The wireless network 100 may include one or more relay stations. A relay station is a network entity that can receive transmissions of data from an upstream station (e.g., a network entity or UE 120) and transmit transmissions of data to a downstream station (e.g., a UE 120 or a network entity). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in FIG, BS 110d (eg, a relay base station) can communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. Base station 110 that relays communication may be referred to as a relay station, relay base station, relay, or the like.

[0041] The wireless network 100 may be a heterogeneous network having network entities including different types of BSs, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0042] The network controller 130 may be coupled to or in communication with a set of network entities and may provide coordination and control for these network entities. The network controller 130 may communicate with the base station 110 via a backhaul communication link. The network entities may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link.

[0043] UE 120 can be dispersed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 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, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate via a wireless medium.

[0044] Some UE 120 may be considered as machine type communication (MTC) UE or evolved or enhanced machine type communication (eMTC) UE. MTC UE and / or eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor and / or a location tag, which may communicate with a network entity, another device (e.g., a remote device) or some other entity. Some UE 120 may be considered as an Internet of Things (IoT) device and / or may be implemented as a NB-IoT (narrowband IoT) device. Some UE 120 may be considered as user premises equipment. UE 120 may be included in a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the 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 operationally coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0045] Generally speaking, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, an air interface, etc. Frequency may be referred to as a carrier, a frequency channel, etc. In a given geographic area, each frequency may support a single RAT to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0046] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using a network entity as an intermediary to communicate 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) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0047] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0048] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0049] In view of the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term can be broadly referred to as frequencies that can be lower than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term can be broadly referred to as frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1 and / or FR5, or can be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0050] In some aspects, the first device (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may send an indication of interference cancellation (IC) capabilities of the first device. The communication manager 140 may receive resource information for sidelink communications from the second device. The communication manager 140 may receive sidelink communications based at least in part on the resource information and perform actions based at least in part on the IC capabilities.

[0051] In some aspects, the communication manager 140 may send an indication of a preferred resource for sidelink communication based at least in part on the IC capabilities of the first device. The communication manager 140 may receive sidelink communication from the second device. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0052] In some aspects, the second device (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive an indication of the IC capabilities of the first device from the first device. The communication manager 140 may select one or more resources for sidelink communication based at least in part on the IC capabilities of the first device and send resource information indicating the one or more resources to the first device. The communication manager 140 may send the sidelink communication based at least in part on the resource information. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0053] As indicated above, Figure 1 Other examples can be found in the Figure 1 The examples described are different.

[0054] Figure 2 2 is a diagram illustrating an example 200 of a network entity (e.g., base station 110) communicating with UE 120 in a wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0055] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a group of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and provide data symbols for the UE 120. The transmit processor 220 may 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 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)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may further process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0056] At the UE 120, a group of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from the base station 110 and / or other base stations 110, and a group of received signals (e.g., R received signals) can be provided to a group of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert and / or digitize) the received signal to obtain input samples. Each modem 254 can use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain received symbols from the modem 254, can perform MIMO detection on the received symbols where applicable, and can provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the 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 things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0057] 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 network entities via the communication unit 294.

[0058] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more group antenna elements, and / or one or more antenna arrays, etc. An antenna panel, an antenna group, a group of antenna elements, and / or an antenna array may include one or more antenna elements (in a single housing or multiple housings), a group of coplanar antenna elements, a group of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0059] 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, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to a network entity. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (eg, with reference to Figures 3 to 10 ).

[0060] At a network entity (e.g., base station 110), uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., a demodulator component of modem 232 shown as DEMOD), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240. The network entity may include a communication unit 244 and may communicate with network controller 130 via communication unit 244. The network entity may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network entity may include a modulator and a demodulator. In some examples, the network entity includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 3 to 10 ) or any aspect of any of the methods described herein.

[0061] As described in more detail elsewhere herein, a controller / processor of a network entity (e.g., controller / processor 240 of base station 110), controller / processor 280 of UE 120, and / or Figure 2 Any other components of may perform one or more techniques associated with using side link resources based on IC capabilities. In some aspects, the first device described herein is a UE 120, is included in a UE 120, or includes Figure 2 In some aspects, the second device described herein is UE 120, is included in UE 120, or includes Figure 2 One or more components of the UE 120 shown. For example, the controller / processor 280 and / or Figure 2 Any other component of the can perform or direct e.g. Figure 7 The process of 700 Figure 8 The process of 800 Fig. 9 900 and / or operations of other processes as described herein. Memory 282 may store data and program codes for UE 120. In some examples, 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, the one or more instructions, when executed by one or more processors of UE 120 (e.g., directly executed, or executed after compilation, conversion, and / or interpretation), may cause the one or more processors and / or UE 120 to perform or direct, for example, Figure 7 The process of 700 Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0062] In some aspects, the first device (e.g., UE 120) includes means for sending an indication of IC capabilities of the first device; means for receiving resource information for sidelink communication from a second device; means for receiving sidelink communication based at least in part on the resource information; and / or means for performing IC based at least in part on IC capabilities. In some aspects, the means for the first device to perform the operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0063] In some aspects, the first device includes: means for sending an indication of preferred resources for sidelink communications, the preferred resources based at least in part on IC capabilities of the first device; and / or means for receiving sidelink communications from a second device.

[0064] In some aspects, the second device (e.g., UE 120) includes means for receiving an indication of the IC capabilities of the first device from the first device; means for selecting one or more resources for sidelink communication based at least in part on the IC capabilities of the first device; means for sending resource information indicating one or more resources to the first device; and / or means for sending sidelink communication based at least in part on the resource information. In some aspects, the means for the second device to perform the operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0065] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these 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.

[0066] As indicated above, Figure 2 Other examples can be found in the Figure 2 The examples described are different.

[0067] Figure 3 is a diagram illustrating an example 300 of sidelink communications according to the present disclosure.

[0068] like Figure 3As shown in , 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. UEs 305-1 and 305-2 can communicate using one or more side link channels 310 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication and / or V2P communication) and / or mesh networks. 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 a transmit time interval (TTI) (e.g., a frame, subframe, time slot, or symbol).

[0069] like Figure 3 As 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 communication 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 communication 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 communication, such as one or more resources (e.g., time resources, frequency resources, and / or space resources), wherein 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 330, such as hybrid automatic repeat request (HARQ) feedback (eg, acknowledgement or negative acknowledgement (ACK / NACK) information), transmit power control (TPC), and / or scheduling request (SR).

[0070] Although shown on the PSCCH 315, in some aspects the SCI 330 may include multiple communications in different levels, such as a first level SCI (SCI-1) and a second level SCI (SCI-2). The SCI-1 may be sent on the PSCCH 315. The SCI-2 may be sent on the PSSCH 320. The SCI-1 may include, for example, an indication of one or more resources (e.g., time resources, frequency resources, and / or space resources) on the PSSCH 320, information for decoding sidelink communications on the PSSCH, a quality of service (QoS) priority value, a resource reservation period, a PSSCH demodulation reference signal (DMRS) pattern, an SCI format for SCI-2, a beta offset for SCI-2, a number of PSSCH DMRS ports, and / or an MCS. SCI-2 may include information associated with data transmission on the PSSCH 320, such as a hybrid automatic repeat request (HARQ) process ID, a new data indicator (NDI), a source identifier, a destination identifier, and / or a channel state information (CSI) report trigger.

[0071] 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, data transmissions 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 transmissions are not sent on adjacent RBs.

[0072] In some aspects, UE 305 may operate using a sidelink transmission mode (e.g., Mode 1) where resource selection and / or scheduling is performed by base station 110. For example, UE 305 may receive a grant for sidelink channel access and / or scheduling from base station 110 (e.g., in downlink control information (DCI) or in a radio resource control (RRC) message, such as a grant for configuration). In some aspects, UE 305 may operate using a transmission mode (e.g., Mode 2) where resource selection and / or scheduling is performed by UE 305 (e.g., instead of base station 110). In some aspects, UE 305 may perform resource selection and / or scheduling by sensing channel availability for transmission. For example, UE 305 may measure RSSI parameters associated with various side link channels (e.g., sidelink-RSSI (S-RSSI) parameters), may measure RSRP parameters associated with various side link channels (e.g., PSSCH-RSRP parameters), and / or may measure RSRQ parameters associated with various side link channels (e.g., PSSCH-RSRQ parameters), and may select a channel for sending side link communications based at least in part on the measurement results.

[0073] 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 and / or channel parameters. Additionally or alternatively, the UE 305 may perform resource selection and / or scheduling by determining a channel busy rate (CBR) associated with each sidelink channel, 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).

[0074] In a transmission mode in which resource selection and / or scheduling is performed by the UE 305, the UE 305 may generate a sidelink grant and may transmit 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 (e.g., for TB 335) to be used for an upcoming sidelink transmission on the PSSCH 320, one or more subframes to be used for an upcoming sidelink transmission, and / or an MCS to be used for an upcoming sidelink transmission. In some aspects, the UE 305 may generate a sidelink grant indicating one or more parameters (such as the periodicity of the sidelink transmission) for semi-persistent scheduling (SPS). Additionally or alternatively, the UE 305 may generate a sidelink grant for event-driven scheduling (such as for an on-demand sidelink message).

[0075] As indicated above, Figure 3Other examples can be found in the Figure 3 The examples described are different.

[0076] Figure 4 is a diagram illustrating an example 400 of side link communications and access link communications according to the present disclosure.

[0077] 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 4 As further shown in the figure, in some sidelink modes, the base station 110 can communicate with the Tx / Rx UE 405 via the first access link. Additionally or alternatively, in some sidelink modes, the base station 110 can communicate with the Rx / Tx UE 410 via the second access link. 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 1 120. Thus, a direct link between UEs 120 (e.g., via a PC5 interface) may be referred to as a side link, and a direct link between a base station 110 and a UE 120 (e.g., via a Uu interface) may be referred to as an access link. Side link communications may be sent via a side link, and access link communications may be sent via an access link. Access link communications may be downlink communications (from a base station 110 to a UE 120) or uplink communications (from a UE 120 to a base station 110).

[0078] As indicated above, Figure 4 Other examples can be found in the Figure 4 The examples described are different.

[0079] Figure 5 5 is a diagram illustrating an example 500 of selecting sidelink resources according to the present disclosure. Example 500 shows a UE 502 (eg, UE 502) that can receive communications on a sidelink channel from other UEs (eg, UE 504) such as UE 504, UE 506, and / or UE 508.

[0080] As combined Figure 55. In the example 500, UE 504 is a transmitting UE that transmits communications to UE 502, which is a receiving UE. UE 504 may use reports from UE 502, which may act as a reporting UE that reports available sidelink resources, preferred sidelink resources, non-preferred sidelink resources, or sidelink resource conflicts. Example 500 shows availability reports from UE 502 to UE 504 and communications from UE 504 to UE 502. The report may be request-based (e.g., requested by UE 504) or condition-based (e.g., UE 502 determines whether to transmit the report).

[0081] If UE 504 is to send a communication to UE 502, UE 504 can sense the side link channel in a sensing window to determine which side link resources (e.g., subcarriers, subchannels) are available. If the side link resource is idle or has a signal energy (e.g., RSRP) that meets an availability threshold (e.g., interference or energy measured on the channel is below a maximum decibel-milliwatt (dBm) or dB, RSRP threshold), the side link resource can be considered available. The availability threshold can be configured or pre-configured according to a transmit priority and a receive priority pair. Depending on the configuration, UE 504 can measure the DMRS on the PSCCH or PSSCH.

[0082] For example, UE 504 may prepare to send a communication to UE 502. UE 504 may have sensed previous sidelink resources and successfully decoded SCIs from UE 506 and UE 508. UE 504 may attempt to reserve sidelink resources and thus may check the availability of future sidelink resources reserved by UE 506 and UE 508 by sensing the sidelink channel in the sensing window. UE 504 may measure the RSRP of the signal from UE 508 in the sidelink resource 510 and the RSRP of the signal from UE 506 in the sidelink resource 512. If the observed RSRP (RSRP projection) meets the RSRP threshold (e.g., below the maximum RSRP), the corresponding sidelink resource may be used for reservation by UE 504. UE 504 may reserve sidelink resources (which may be a random selection from available resources). For example, UE 504 may select and reserve sidelink resources 514 for transmission. This may be done in a time slot after which the side link resources have been used by UE 506 and UE 508 and which UE 504 may have sensed earlier. UE 504 may select and reserve side link resources only when a threshold level (e.g., 20%, 30%, or 50% availability) is reached. UE 504 may increase or decrease the RSRP threshold as needed to reach the threshold level. UE 504 may select and reserve side link resources in the current time slot and up to two (or more) future time slots. Reservation may be aperiodic or periodic (e.g., SCI signal period between 0 ms and 1000 ms). Periodic resource reservation may be disabled.

[0083] At processing time T proc,0 Afterwards and at another processing time T proc,1 Before, there may be a resource selection trigger for triggering the selection of the side link resource, followed by a resource selection window from which the side link resource may be obtained. The resource selection window may be a time window from which the side link resource may be selected, and the resource selection window may be extended for the remaining packet delay budget (PDB).

[0084] UE 504 may be power sensitive and therefore may not be able to continuously sense all side link resources. Since, for example, UE 502 may be a smart phone and UE 504 may be a smart watch, UE 502 may be more able to sense and report side link resources. UE 502 may receive unicast communications from UE 504, and UE 502 may report back available resources to UE 504. UE 502 may continuously sense side link resources and measure interference levels involving neighboring UEs. For example, UE 502 may measure the RSRP of a signal from neighboring UE 506 to be -92dBm, and measure the RSRP of a signal from neighboring UE 508 to be -102dBm. For the last transmitted signal of UE 504, the RSRP of the target signal level that UE 502 may have measured is -90dBm. UE 502 may estimate the signal-to-interference ratio (SIR) of the signal between UE 502 and UE 504 to be -90 - (-92) = 2 dB, and estimate the SIR between UE 504 and UE 508 to be -90 - (-102) = 12 dB. If the SIR of the signal from UE 504 to UE 502 with interference from UE 508 is large enough (meets the availability threshold) for reliable communication between UE 502 and UE 504, UE 502 may mark the sidelink resources reserved by UE 508 as available for communication from UE 504 to UE 502. This may be useful when UE 504 has more than one data stream with different QoS requirements or transmissions with different MCS indices.

[0085] UE 502 may send a report indicating the availability of each side link resource. The rows in the report may represent subcarriers or subchannels, and the columns may represent time units (e.g., time slots, symbols). The report may be a binary report, such as a bitmap. For example, UE 502 may report 1 bit to indicate availability, and report 0 bit to indicate unavailable. UE 504 may decode the report and select N resources (e.g., randomly) from the available side link resources for potential N transmissions of packets of newly generated packets or previously unsent transport blocks. UE 504 may select N=4 side link resources from the available side link resources indicated by the report. UE 504 may also use the report to perform retransmission or resource reselection.

[0086] In some aspects, the report may involve different inter-UE coordination schemes that report different information. For example, the report may include information of type A indicating one or more preferred side link resources for transmission. The report may include information of type B indicating one or more non-preferred side link resources for transmission. The report may include information of type C indicating an expected, potential, or detected collision of one or more side link resources. Information of type A and type B may be used for a first inter-UE coordination scheme, and information of type C may be used for a second inter-UE coordination scheme. The report may involve a selection of reported resources.

[0087] In some scenarios, the UE 502 may be capable of IC in sidelink reception. IC involves eliminating interference to obtain a better signal. The IC may be a symbol-level IC (SLIC). The UE 502 may perform channel estimation and demodulation on the received signal, obtain hard decisions, and reconstruct the received interference signal. The UE 502 may perform IC and detect the desired signal. The IC may be a codeword-level IC (CWIC), in which decoding is further performed. CWIC may be more robust than SLIC.

[0088] UE 502 may decode the first transmission, perform IC, and decode another transmission in the same resource. Thus, as an IC-capable UE, UE 502 may be able to decode overlapping transmissions (two transmissions transmitted in overlapping resources). Overlapping transmissions may be common in sidelink autonomous resource allocation. In a broadcast / multicast-dominated network (e.g., V2X), if UE 502 uses IC, there may be less interference in the overlapping transmissions. That is, from the perspective of the receiver UE, the received transmission may be the desired signal. V2X reliability and network capacity may be improved using IC operation.

[0089] IC has not been considered for resource preference indication. A resource may be determined as "preferred" if it has not been reserved by another UE, or if it has been reserved but the RSRP measured from the reservation signal (e.g., SCI) is below the RSRP threshold. A resource may be determined as "non-preferred" if it has been reserved by another UE and the RSRP measured from the reservation signal (e.g., SCI) is above the RSRP threshold. In addition, sidelink receiver capabilities (such as IC capabilities) have not been considered in resource preference determination.

[0090] As indicated above, Figure 5 Other examples can be found in the Figure 5 The examples described are different.

[0091] Figure 6600 is a diagram illustrating an example of using beams for communication according to the present disclosure. Figure 6 As shown in , a first device 610 (eg, UE 120, UE 502) may communicate with a second device UE 620 (eg, UE 120, UE 504) using a side link.

[0092] The first device 610 (receiving UE) may be prepared to receive side link communications from the second device 620 (transmitting UE) in reserved resources. The second device 620 may select reserved resources from candidate resources determined to be available through sensing. The first device 610 may indicate preferred resources (or non-preferred resources) for side link communications to the second device 610. The second device 620 may select reserved resources for use from preferred resources rather than non-preferred resources. If the first device 610 is capable of IC (having IC capabilities), the resource selection may be enhanced. According to various aspects described herein, resources may be selected based at least in part on the IC capabilities of the first device 610. The IC capabilities may be indicated as part of inter-UE coordination. Therefore, preferred resources and reserved resources may be selected to take into account the ability of the first device 610 to perform IC.

[0093] There may be at least two scenarios in which consideration of IC capabilities may be beneficial to inter-UE coordination. In the first scenario (scenario 1), the first device 610 may be the intended recipient of a transmission from the second device 620. The first device 610 may determine resource preferences based at least in part on the IC capabilities of the first device 610. For example, a preferred resource based on the IC capabilities of the first device 610 may have an RSRP threshold greater than an RSRP threshold for a preferred resource not based on the IC capabilities of the first device 610. Candidate resources for IC capabilities may be sensed with an RSRP threshold greater than an RSRP threshold for candidate resources without IC capabilities. In some aspects, the first device 610 may indicate the maximum MCS or spectral efficiency that the first device 610 may support for each preferred resource in the preferred resources. If the first device 610 has IC capabilities, the maximum MCS may be higher. In some aspects, the second device 620 may be multicast or broadcast, and the first device 610 may not know the IC capabilities of the second device 620 or the recipient of the second device 620. When determining preferred or non-preferred resources for the second device 620, the first device 610 can indicate whether IC capability is present.

[0094] In a second scenario (Scenario 2), the first device 610 may be a standby UE that assists the second device 620 with its resource allocation but is not a recipient of the sidelink communication from the second device 620. The first device 610 may or may not know the IC capability of the second device 620 or the recipient of the second device 620. In some aspects, the second device 620 may indicate or hint in a transmission from the second device 620 whether the reserved resources or candidate resources consider the IC capability. The first device 610 may determine the resource preference based at least in part on the indication or hint.

[0095] In some aspects, the first device 610 may not be aware of any IC capabilities considered by the second device 620, and may indicate whether the IC capabilities are presented for preferred resources or non-preferred resources. For example, the first device 610 may determine a first resource set that presents IC capabilities. The first device 610 may also determine a second resource set that does not present any IC capabilities. The first device 610 may indicate both the first resource set and the second resource set to the second device 620. The first resource set and the second resource set may be used for preferred resources or for reserved resources. The first resource set may not include the second resource set.

[0096] In some aspects, the first resource set and the second resource set may be used for non-preferred resources. The first device 610 may determine a first non-preferred resource set that presents IC capability. Note that if a resource is determined to be non-preferred assuming that the recipient has IC capability, the resource may also be non-preferred when the recipient does not have IC capability. If the RSRP measured for the resource is greater than the RSRP threshold, the resource may be determined to be non-preferred. The first device 610 may determine a second non-preferred resource set that does not present any IC capability. This may involve a smaller RSRP threshold. For example, if the associated RSRP threshold of a resource is greater than a smaller RSRP threshold but less than a larger RSRP threshold, the resource may be in the second resource set. The second device 620 may exclude non-preferred resources from resource selection based on the IC capability of the intended recipient. The second device 620 may exclude non-first non-preferred resource sets when the recipient has IC capability, and exclude both the first resource set and the second resource set when at least one intended recipient does not have IC capability (or the second device 620 does not know the IC capability of the intended recipient).

[0097] Example 600 shows an example of scenario 1. As shown by reference numeral 625, the first device 610 may send an inter-UE coordination message (e.g., via an SCI or a medium access control element (MAC CE)). The inter-UE coordination message may indicate one or more preferred resources. The inter-UE coordination message or a separate message may indicate the IC capability of the first device 610. The IC capability may be when the first device 610 may perform IC and / or to what extent the first device 610 may perform IC. For example, the inter-UE coordination message or a separate message may indicate, for each preferred resource in the preferred resources, the maximum MCS that can be supported in the resource, the recommended CQI index of the resource, and / or the maximum or recommended spectral efficiency of the resource. IC capability (or greater IC capability) may enable the use of a greater MCS, CQI index, or spectral efficiency. A smaller IC capability or no IC capability may only allow a smaller MCS, CQI index, or spectral efficiency because interference is not eliminated and the signal to interference plus noise ratio (SINR) may be smaller. The second device 620 may determine the MCS based at least in part on the indicated CQI index or spectral efficiency.

[0098] In some aspects, the first device 610 may determine the maximum MCS, CQI index and / or spectral efficiency in various ways. For example, the first device 610 may estimate the signal power based on a reference signal transmitted by the second device 620 in a previous transmission of the second device 620. The first device 610 may estimate the interference power and the noise power based on a signal transmitted by another device that reserves a preferred resource. If the preferred resource is a resource that is not reserved by other devices, the first device 610 may assume that the interference power is 0 (zero). The first device 610 may determine the SINR based on the estimate. Taking into account the IC capability of the first device 610, the first device 610 may map the SINR to the maximum MCS, CQI index or spectral efficiency.

[0099] In some aspects, the first device 610 may indicate two or more maximum MCSs, CQI indices, or spectral efficiencies. For example, the first device may determine and indicate a maximum MCS, CQI index, and / or spectral efficiency assuming that the first device 610 will perform IC, and determine and indicate another maximum MCS, CQI index, and / or spectral efficiency assuming that the first device 610 will not perform IC. The second device 620 may determine the MCS based at least in part on the preference indications from all intended recipients.

[0100] As shown by reference numeral 630, the second device 620 may select resources for sidelink communication based at least in part on the IC capability of the first device 610. The second device 620 may also select resources based at least in part on the maximum MCS, CQI index and / or spectral efficiency. The second device 620 may select resources from the preferred resources indicated in the inter-UE coordination message. The preferred resources may be based at least in part on the IC capability of the first device 610. If the first device 610 indicates that the preferred resources are based on the IC capability of the first device 610, the second device 620 may select the preferred resources or other resources based at least in part on the IC capability (more tolerant to interference) of the first device 610. If the first device 610 indicates that the preferred resources are not based on the IC capability of the first device 610, the second device 620 may select the preferred resources or other resources based at least in part on the first device 610 not having the IC capability (or not knowing the IC capability). As shown by reference numeral 635, the second device 620 may send resource information indicating the selected resources. The selected resources may indicate available resources and / or reserved resources.

[0101] In some aspects, the second device 620 may indicate the IC capabilities of the first device 610 or another intended recipient in resource information or in later communications (e.g., a field in the SCI). For example, the second device 620 may indicate that the resource information is intended for a device with IC capabilities or is not intended for a device with IC capabilities. The second device 620 may indicate the above situation in an inter-UE coordination message or in a transmission using a destination identifier (ID). The second device 620 may indicate whether the resource information is intended for a device with IC capabilities or is not intended for a device with IC capabilities by implication or by a configuration with a side link resource pool configuration. For example, transmission to a device with IC capabilities may be performed in a dedicated resource pool. When the first device 610 indicates a preferred resource from a dedicated resource pool, a recipient using resources from the dedicated resource pool may be assumed to have IC capabilities.

[0102] In some aspects, the first device 610 may determine the preferred resources based at least in part on the intended recipient of the IC capability of the second device 620. If the intended recipient of the transmission of the second device 620 is IC-capable, the first device 610 may assume that the transmission of the second device 620 is more tolerant to interference. Therefore, the first device 610 may apply a larger RSRP threshold when determining resource availability. For example, if the transmission of the second device 620 is intended for a recipient without IC capability, the first device 610 may apply an RSRP threshold (RSRP_1) to determine whether the reserved resources are available based at least in part on the RSRP measured from the signaling for making a reservation. If the transmission of the second device 620 is intended for a recipient with IC capability, the first device 610 may apply a different RSRP threshold (RSRP_2) to determine whether the reserved resources are available based at least in part on the measured RSRP from the signaling for making a reservation. If the associated RSRP is greater than RSRP_2 and RSRP_1 is less than RSRP_2, the resource may be excluded from the preferred resources. There may be multiple preferred resource sets associated with multiple RSRP thresholds.

[0103] For non-preferred resources, the first device 610 may use RSRP_1 for the first non-preferred resource set, and then apply a larger RSRP_2 to the first non-preferred resource set to identify resources for the second non-preferred resource set. The remaining resources in the first non-preferred resource set may belong to a third non-preferred resource set (e.g., set 1 is the union of set 2 and set 3). If not all receivers have IC capabilities (or if the second device 620 does not know the IC capabilities of the receiver), the second device 620 may exclude both the second non-preferred resource set and the third non-preferred resource set during resource selection. If the receiver of the second device 620 has IC capabilities, only the second non-preferred resource set may be excluded during resource selection. There may be multiple non-preferred resource sets associated with multiple RSRP thresholds.

[0104] As indicated by reference numeral 640, the second device 620 may use the selected resources to send the sidelink communication. If scenario 2 is involved and the first device 610 is a backup UE and not a recipient of the sidelink communication, as indicated by reference numeral 645, the second device 620 may use the information provided by the first device 610 to send the sidelink communication to the third device 650. The second device 620 may send the resource information to the third device 650 before sending the communication.

[0105] As indicated by reference numeral 655, the first device 610 may perform an action. The action may include receiving a sidelink communication. The action may also include decoding the sidelink communication. For example, the sidelink communication may be a transport block, and the first device 610 may decode the transport block based at least in part on an SCI associated with the transport block. The first device 610 may also decode the SCI before decoding the transport block.

[0106] In some aspects, the action may include performing IC on the side link communication. This may include eliminating interference to obtain a better signal. The first device 610 may reconstruct the received interference signal and eliminate the interference signal to detect the desired signal. The first device 610 may eliminate interference at the symbol level or the codeword level. The first device 620 may perform IC only on the resource information. Successful decoding can help reconstruct the interference signal and / or detect the desired signal.

[0107] In some aspects, the action may include reporting the interference signal for the IC. This may include sending information about the interference signal and / or the IC. In some aspects, the action may include recording the interference signal.

[0108] By considering the IC capabilities of the devices in inter-UE coordination, resource selection can be improved. The improved resource selection improves communication and allows the sidelink devices to conserve processing resources and signaling resources.
