Description

[0001] Cross-reference to related applications

[0002] This patent application claims priority to Greek patent application No. 20210100268 entitled "SIDELINK RESOURCESCHEDULING", filed on April 15, 2021, which has been assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to wireless communication and techniques and apparatus for sidelink resource scheduling. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems 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 issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more base stations that can support communication for user equipment (UE) or multiple UEs. UEs can communicate with base stations via downlinks and uplinks. A downlink (or "DL") refers to the communication link from the base station to the UE, while an uplink (or "UOL") refers to the communication link from the UE to the base station.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR), also known as 5G, is a set of enhancements to the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR aims to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using OFDM with a cyclic prefix (CP-OFDM) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation for better integration with other open standards. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0029] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0030] Several aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various boxes, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “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 system as a whole.

[0031] While the terms commonly associated with 5G or New Radio (NR) Radio Access Technologies (RATs) may be used to describe the aspects herein, the aspects of this disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).

[0032] Figure 1This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, as well as other examples. The wireless network 100 may include one or more base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. Base station 110 is the entity that communicates with 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 specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term “cell” can refer to the coverage area of ​​base station 110 and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0033] Base station 110 can provide communication coverage for macro cells, pico cells, femtocells, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., an area with a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with a service subscription. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Base station 110 for macro cells can be referred to as a macro base station. Base station 110 for pico cells can be referred to as a pico base station. Base station 110 for femtocells can be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS110a can be a macro base station for macro cell 102a, BS110b can be a pico base station for pico cell 102b, and BS110c can be a femto base station for femto cell 102c. A base station can support one or more (e.g., three) cells.

[0034] In some examples, the cell may not necessarily be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base stations 110 may be interconnected with each other and / or interconnected to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0035] Wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., base station 110 or UE 120) and send data to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 capable of relaying transmissions used by other UEs 120. Figure 1 In the example shown, BS110d (e.g., a relay base station) can communicate with BS110a (e.g., a macro base station) and UE 120d to facilitate communication between BS110a and UE 120d. The base station 110 for relay communication can be referred to as a relay station, relay base station, relay, etc.

[0036] Wireless network 100 can be a heterogeneous network, comprising different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 can have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro base stations can have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0037] Network controller 130 may be coupled to or communicate with a set of base stations 110, and may provide coordination and control for these base stations 110. Network controller 130 may communicate with base stations 110 via backhaul communication links. Base stations 110 may communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0038] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 can be a cellular phone (e.g., a smartphone), 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 smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or 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, industrial manufacturing equipment, a GPS device, and / or any other suitable device configured to communicate via a wireless medium.

[0039] Some UEs 120 may be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UE 120 may be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0040] Typically, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology, air interface, etc. A frequency can be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0041] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UEs 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, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0042] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as frequency ranges named FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often referred to (interchangeably) as the “below 6GHz” band in various documents and articles. A similar naming issue sometimes occurs with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz-300GHz) identified as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0043] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands of these mid-band frequencies as the frequency range named FR3 (7.125GHz-24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6GHz. For example, three higher operating frequency bands have been identified as the frequency ranges named FR4a or FR4-1 (52.6GHz-71 GHz), FR4 (52.6GHz-114.25GHz), and FR5 (114.25GHz-300 GHz). Each of these higher frequency bands falls within the EHF band.

[0044] Considering the examples above, unless otherwise specified, it should be understood that the terms "below 6 GHz," if used herein, can broadly refer to frequencies that can be less than 6 GHz, within FR1, or may include intermediate frequency band frequencies. Furthermore, unless otherwise specified, it should be understood that the terms "millimeter wave," if used herein, can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is contemplated that 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.

[0045] In some respects, the terms "base station" (e.g., base station 110), "network node," or "network entity" can refer to aggregation base stations, deaggregation base stations (e.g., combined base stations), and so on. Figure 9 The term "base station," "network node," or "network entity" can refer to a central unit (CU), distributed unit (DU), radio unit (RU), near real-time (near RT) RAN intelligent controller (RIC), or non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the terms "base station," "network node," or "network entity" can refer to a device configured to perform one or more functions (e.g., those described herein in conjunction with base station 110). In some aspects, the terms "base station," "network node," or "network entity" can refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) can be configured to perform at least a portion of a function, or replicate the performance of at least a portion of a function, and the terms "base station," "network node," or "network entity" can refer to any one or more of those different devices. In some aspects, the terms "base station," "network node," or "network entity" can 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 can be instantiated on a single device. In some aspects, the terms "base station," "network node," or "network entity" may refer to one of the base station functions rather than the other. In this way, a single device can include more than one base station.

[0046] As mentioned above, Figure 1 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 1 The examples described are different.

[0047] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with antenna sets 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with antenna sets 252a to 252r, such as R antennas (R≥1).

[0048] At base station 110, transmitting processor 220 can receive data for UE 120 (or a set of UE 120) from data source 212. Transmitting processor 220 can select one or more modulation and coding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Base station 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can 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. Transmitting processor 220 can 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 signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to the corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can 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).

[0049] At UE 120, antenna set 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110, and can provide a set of received signals (e.g., R received signals) to modem set 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 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 an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, can perform MIMO detection on the received symbols (if applicable), and can provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control and system information to the controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, among other examples. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0050] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0051] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or be included therein, one or more antenna panels, one or more antenna groups, one or more antenna element sets, and / or one or more antenna arrays. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), coplanar antenna element sets, non-coplanar antenna element sets, and / or coupled to one or more transmitting and / or receiving components (such as…) Figure 2 One or more antenna elements (one or more components).

[0052] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). Transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded (if applicable) by TX MIMO processor 266, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, modem 254 of UE 120 may include modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform the functions described herein (e.g., as referenced). Figures 3-10 (Description) All aspects of any method.

[0053] At base station 110, uplink signals from UE 120 and / or other UEs can be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antenna(s) 234, modem(s) 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. Processors (e.g., controller / processor 240) and memory 242 may be used with the transceiver to perform the functions described herein (e.g., as referenced). Figures 3-10 (Description) All aspects of any method.

[0054] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other components may perform one or more associated technologies, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component (or multiple components) can perform or direct, for example... Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for base station 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, transformation, and / or interpretation), one or more instructions may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. In some examples, execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, and other examples.

[0055] In some aspects, the UE includes: components for transmitting sidelink resource reservations, wherein the sidelink resource reservations indicate a first resource in an uplink time slot having a first bandwidth available for the sidelink resource reservations and a second resource in a subband full-duplex (SBFD) time slot having a second bandwidth available for the sidelink resource reservations, and wherein the sidelink resource reservations are configured using the same subchannel index for the uplink time slots and the SBFD time slots; and / or components for transmitting communications using the sidelink resource reservations. Components for the UE to perform the operations described herein may include one or more of, for example, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0056] In some respects, the UE includes components for transmitting communications without using invalid frequency resources of the SBFD time slots.

[0057] In some aspects, the UE includes: components for receiving sidelink resource reservations, wherein the sidelink resource reservations indicate a first resource in an uplink timeslot having a first bandwidth available for the sidelink resource reservations and a second resource in an SBFD timeslot having a second bandwidth available for the sidelink resource reservations, and wherein the sidelink resource reservations use the same subchannel index configuration for the uplink timeslots and the SBFD timeslots; and / or components for decoding communications at least in part based on the sidelink resource reservations. Components for the UE to perform the operations described herein may include one or more of, for example, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0058] In some respects, the UE includes components for decoding communications without using invalid frequency resources of the SBFD time slot.

[0059] Although Figure 2 The boxes are shown as different components, but the functions described above with respect to the boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be performed by the controller / processor 280 or under the control of the controller / processor 280.

[0060] As mentioned above, Figure 2 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 2 The examples described are different.

[0061] Figure 3 This is a diagram illustrating example 300 of sidelink communication according to this disclosure.

[0062] like Figure 3As shown, the first UE 305-1 can communicate with the second UE 305-2 (and one or more other UEs 305) via one or more sidelink channels 310. UEs 305-1 and 305-2 can communicate using one or more sidelink channels 310 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication, vehicle-to-person (V2P) communication, mesh networking, etc.), etc. In some aspects, UEs 305 (e.g., UEs 305-1 and / or UEs 305-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, one or more sidelink channels 310 can use a PC5 interface and / or can operate in a high-frequency band (e.g., the 5.9 GHz band). Additionally or alternatively, UEs 305 can use Global Navigation Satellite System (GNSS) timing to synchronize transmission time intervals (TTIs), e.g., frames, subframes, time slots, symbols, etc.

[0063] like Figure 3 As further shown, 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. PSCCH 315 can be used to transmit control information, similar to a Physical Downlink Control Channel (PDCCH) and / or a Physical Uplink Control Channel (PUCCH) for cellular communication with base station 110 via an access link or access channel. PSSCH 320 can be used to transmit data, similar to a Physical Downlink Shared Channel (PDSCH) and / or a Physical Uplink Shared Channel (PUSCH) for cellular communication with base station 110 via an access link or access channel. For example, 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, spatial resources, etc.), wherein a Transport Block (TB) 335 may be carried on PSSCH 320. TB 335 can include data. PSFCH 325 can be used for communication transmission-side link feedback 340, such as Hybrid Automatic Repeat Request (HARQ) feedback (e.g., ACK / NACK information), Transmit Power Control (TPC), Schedule Request (SR), etc.

[0064] In some aspects, one or more sidelink channels 310 may use resource pooling. For example, scheduling assignments may be transmitted across time using specific resource blocks (RBs) in a subchannel (e.g., included in SCI 330). In some aspects, data transmissions associated with scheduling assignments (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, scheduling assignments and associated data transmissions are not transmitted on adjacent RBs.

[0065] In some aspects, UE 305 may operate using a transmission mode in which resource selection and / or scheduling are performed by UE 305 (e.g., rather than 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 Received Signal Strength Indicator (RSSI) parameters (e.g., sidelink-RSSI (S-RSSI) parameters) associated with each sidelink channel, may measure Reference Signal Received Power (RSRP) parameters (e.g., PSSCH-RSRP parameters) associated with each sidelink channel, may measure Reference Signal Received Quality (RSRQ) parameters (e.g., PSSCH-RSRQ parameters) associated with each sidelink channel, etc., and may select the channel for transmitting sidelink communication based at least in part on (multiple) these measurements.

[0066] Alternatively, UE 305 may use SCI 330 received in PSCCH 315 to perform resource selection and / or scheduling, SCI 330 indicating occupied resources, channel parameters, etc. Alternatively, UE 305 may perform resource selection and / or scheduling by determining the Channel Busy Ratio (CBR) associated with each sidelink channel, which may be used for rate control (e.g., by indicating the maximum number of resource blocks that UE 305 can use for a particular set of subframes).

[0067] In the transport mode where UE 305 performs resource selection and / or scheduling, UE 305 can generate sidelink grants and can send grants in SCI 330. Sidelink grants can indicate one or more parameters (e.g., transport parameters) to be used for upcoming sidelink transmissions, such as one or more resource blocks (e.g., for TB 335) to be used for upcoming sidelink transmissions on PSSCH 320, one or more subframes to be used for upcoming sidelink transmissions, and / or modulation and coding configuration (MCS) to be used for upcoming sidelink transmissions, etc. In some aspects, UE 305 can generate sidelink grants indicating one or more parameters (such as the periodicity of sidelink transmissions) for semi-persistent scheduling (SPS). Additionally or alternatively, UE 305 can generate sidelink grants for event-driven scheduling (such as for on-demand sidelink messages).

[0068] SCI 330 may include a first part and a second part, which may be referred to as SCI-1 and SCI-2, respectively. SCI-1 may be transmitted on the PSCCH. SCI-1 may include resource allocation and may include information for decoding SCI-2 (e.g., the format of SCI-2 and / or other information). Resource allocation may indicate resources for SCI-2 and / or the shared channel (SCH). SCI-2 may be transmitted on the PSSCH. SCI-2 may include information for decoding the SCH. SCI-1 and / or SCI-2 may be encoded and / or decoded using a Physical Downlink Control Channel (PDCCH) polarization coding / decoding chain.

[0069] In some aspects, SCI-2 can be mapped to consecutive resource blocks (RBs) in the PSSCH, starting from the first symbol with the PSSCH demodulation reference signal (DMRS). In other aspects, SCI-2 can be scrambled separately from the SCH. In some aspects, quadrature phase shift keying (QPSK) can be used to modulate SCI-2. Since the format of SCI-2 can be indicated by SCI-1, the receiver of SCI-2 can avoid performing blind decoding of SCI-2, thus saving computational resources.

[0070] In some respects, as described elsewhere in this document, SCI-1 can use a common subchannel index configuration for uplink slots and SBFD slots to indicate sidelink resource reservations.

[0071] As mentioned above, Figure 3 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 3 The examples described are different.

[0072] Figure 4 This is a diagram illustrating example 400 of sidelink communication and access link communication according to this disclosure.

[0073] 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. Figure 3 As described. As further shown, in some sidelink modes, base station 110 may communicate with Tx / Rx UE 405 via a first access link. Additionally or alternatively, in some sidelink modes, base station 110 may communicate with Rx / Tx UE 410 via a second access link. Tx / Rx UE 405 and / or Rx / Tx UE 410 may correspond to one or more UEs described elsewhere herein, such as... Figure 1 UE 120. Therefore, the direct link between UE 120 (e.g., via the PC5 interface) can be referred to as a side link, and the direct link between base station 110 and UE 120 (e.g., via the Uu interface) can be referred to as an access link. Side link communication can be transmitted via the side link, and access link communication can be transmitted via the access link. Access link communication can be downlink communication (from base station 110 to UE 120) or uplink communication (from UE 120 to base station 110). In some aspects, as described elsewhere herein, side link communication can be performed via resources of the side link resource pool using a common subchannel index configuration for uplink time slots and SBFD time slots.

[0074] As mentioned above, Figure 4 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 4 The examples described are different.

[0075] Figure 5This is a diagram illustrating Example 500 of a Subband Full-Duplex (SBFD) timeslot according to the present disclosure. Example 500 illustrates a downlink (DL) timeslot, an uplink (UL) timeslot, and two SBFD timeslots. A DL timeslot is a timeslot that can be used for downlink communication from a base station to a UE (such as via a Uu radio access connection). A UL timeslot is a timeslot that can be used for uplink communication from a UE to a base station (such as via a Uu radio access connection) or, in some cases, for sidelink communication between UEs. For example, a UE can communicate on a sidelink via an uplink resource configured as a sidelink resource (such as using a ProSe sidelink (PC5) interface), as described elsewhere herein. In some aspects, a UL timeslot can be configured such that all symbols are uplink symbols (excluding symbols used for gaps, reference signaling, measurements, etc.). In some aspects, a UL timeslot can be a timeslot containing a threshold number of uplink symbols. For example, the symbols for a given timeslot can be configured as downlink symbols, uplink symbols, or another type of symbol. If a threshold number of symbols are configured as uplink symbols, a given timeslot can be considered a UL timeslot. In some aspects, DL timeslots can be configured such that all symbols are downlink symbols (excluding symbols used for gaps, reference signaling, measurements, etc.). In some aspects, a DL timeslot can be a timeslot containing a threshold number of downlink symbols. For example, if a threshold number of symbols are configured as downlink symbols, a given timeslot can be considered a DL timeslot.

[0076] SBFD time slots are time slots configured for SBFD communication. Full-duplex (FD) communication has been introduced as a means to provide increased bandwidth (ideally twice the bandwidth of half-duplex) by allowing gNBs or UEs to transmit and receive on the same set of resources (such as the same time / frequency resource set). However, due to the complexities of transmitting and receiving on the same set of resources (e.g., self-interference between downlink and uplink transmissions, gNB-to-gNB interference, and UE-to-UE interference) and the additional implementation complexities, SBFD is considered a step towards realizing some of the benefits of FD communication while circumventing some of its complexities. For example, in an SBFD time slot, a gap 510 can be configured between downlink resource 520 and UL resource 530, which allows for better control of self-interference while improving latency and uplink coverage. The total bandwidth of example 500 can be a bandwidth portion (BWP), component carrier (CC), etc. SBFD can be implemented at the UE and / or base station. For example, a base station can use SBFD to perform FD communication with multiple UEs (such as uplink communication with one UE and downlink communication with another UE in the same time slot).

[0077] The UE can receive information indicating which time slots are SBFD time slots. For example, information indicating SBFD time slots can be signaled via Public Radio Resource Control (RRC) configuration (such as via System Information Block). As another example, information indicating SBFD time slots can be signaled via UE-specific signaling (such as UE-specific RRC signaling or another form of signaling). As yet another example, information indicating SBFD time slots can be dynamically indicated to the UE (such as through Downlink Control Information (DCI) or Media Access Control (MAC) signaling). In some aspects, UL time slots and / or symbols, as well as DL time slots and / or symbols, can be semi-statically configured, such as via RRC signaling.

[0078] As shown in the figure and described in more detail below, time slots can be subdivided into sub-channels, which the transmitting UE can use to indicate sidelink resource reservations. These sub-channels can be configured using a common sub-channel index between UL time slots and SBFD time slots, which reduces ambiguity in sidelink resource reservations.

[0079] As mentioned above, Figure 5 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 5 The examples described are different.

[0080] Figure 6 This is a diagram illustrating Example 600 of one or more resource pools according to this disclosure. Example 600 illustrates DL time slots, UL time slots, and SBFD time slots including sidelink (sometimes abbreviated as SL) resources. Combined with... Figure 5 These time slot types are described in more detail.

[0081] As described above, sidelink communication can occur via resource pools and can be permitted (e.g., only) on symbols that are semi-statically configured as uplink symbols. A resource pool is a set of time / frequency resources in which a UE is permitted to transmit sidelink communication. It can be seen that resource pools include symbols that are semi-statically configured as uplink symbols, as it is expected that a UE will transmit sidelink communication on such symbols. One or more resource pools in Example 600 are indicated by diagonal padding.

[0082] The UE can be configured (e.g., via configuration signaling such as RRC signaling, via pre-configuration such as by the original equipment manufacturer or service provider) with a set of resource pools, where each resource pool is defined as a time / frequency resource. The smallest unit of transmission / reception in time (e.g., resource allocation) is a subchannel, where each subchannel is defined as a plurality of contiguous resource blocks (RBs).

[0083] The resource pool can also be configured with combinations Figure 3 and Figure 4This describes one of two resource allocation modes. For example, a resource pool can be configured with mode 1 resource allocation, where a network entity such as a gNB assigns resources for sidelink transmissions. In mode 1, dynamic allocation via DCI format 3-x and configured transmissions are supported (type 1, where uplink grant and activation / deactivation signaling for uplink grant are provided via RRC signaling, and type 2, where uplink grant configuration is provided via RRC signaling, and activation / deactivation signaling for uplink grant is provided via control channel grant (e.g., via DCI)). As another example, a resource pool can be configured with mode 2 resource allocation, where the UE senses the resources of the resource pool. Based at least in part on the results of the sensing (e.g., based at least in part on the priority of different transmissions and the reference signal received power (RSRP) determined by sensing), the UE can autonomously select the resources for transmission. In some deployments, mode 1 operation is generally expected for UEs within the coverage area of ​​a network entity (such as a gNB), while mode 2 operation is generally expected for UEs outside the coverage area of ​​a network entity.

[0084] The UE can receive information indicating multiple time / frequency resources for a resource pool and can identify a set of sidelink time slots to be included in the resource pool. For example, a set of sidelink time slots can be identified (e.g., selected) from resources. In some cases, the set of time slots that may belong to the sidelink resource pool is determined by… To indicate, among which, Wherein, the slot index is relative to slot #0 of the radio frame corresponding to System Frame Number (SFN) 0 or Direct Frame Number (DFN) 0 of the serving cell, and where μ is the subcarrier spacing of the BWP or CC under discussion. The sidelink slot set may include all slots except the following:

[0085] ·N S_SSB Each time slot is configured with a side link synchronization signal / physical side link broadcast channel (S-SSB) block (S-SSB);

[0086] ·N nonSL In each time slot, at least one of the Y-th, (Y+1)-th, ..., (Y+X-1)-th OFDM symbols is not semi-statically configured as an uplink according to the higher-layer parameters tdd-UL-DL-ConfigurationCommon or sl-TDD-Configuration, where Y and X are set by the higher-layer parameters sl-StartSymbol and sl-LengthSymbols, respectively; and

[0087] • One or more reserved time slots, which are determined through the following steps:

[0088] a. In addition to N from the set of all time slots S_SSB One time slot and N nonSL The remaining time slots, excluding the first time slot, are arranged in ascending order of their time slot indices. To indicate;

[0089] b. If Then time slot This is a reserved time slot. Here, m = 0, 1, ..., N reserved -1a and Among them, L bitmap This indicates the length of the bitmap and is configured by higher layers (such as using resource pool configuration information or separate from resource pool configuration information).

[0090] The set of side link time slots can be arranged in ascending order of time slot index.

[0091] Configuration information for a resource pool (e.g., information identifying multiple resources for the resource pool) can indicate multiple time slots, and the UE can select a set of time slots from these multiple time slots, as described above. The configuration information can use a bitmap associated with the resource pool. To indicate multiple time slots, where L bitmap (For example, the length of the bitmap) is configured by higher layers, as described above. If b k′ =1, then time slot Belongs to the set, where k′=kmod L bitmap The time slots in the set can be reindexed, making the remaining time slots available. The subscript i is consecutive {0,1,…,T′} max -1}, where T′ max It represents the number of remaining time slots in the set.

[0092] Example 600 is an example of performing Uu operations (e.g., between the UE and the base station) and sidelink operations (e.g., between UEs) within the same bandwidth (such as on the same carrier). This may occur, for example, when a sidelink network is deployed in a licensed spectrum. Furthermore, Example 600 is an example where at least the gNB (and potentially one or more UEs) supports SBFD operations. Therefore, at least some time slots in Example 600 (e.g., the rightmost time slot) are configured (dynamically or semi-statically) as SBFD time slots. Consequently, the bandwidth of the uplink portion of the SBFD time slot is less than the bandwidth of the uplink time slot in Example 600. It can be seen that the smaller bandwidth of the uplink portion of the SBFD time slot reduces the bandwidth of the resource pool within the SBFD time slot relative to the uplink time slot, because the UE cannot use downlink or gap resources for the resource pool. The techniques and apparatus described herein provide a common subchannel index for use in UL and SBFD time slots, such that, for example, there is no ambiguity regarding whether “subchannel index X” refers to the Xth subchannel of the SBFD time slot or the Xth subchannel of the resource pool within the SBFD time slot.

[0093] As mentioned above, Figure 6 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 6 The examples described are different.

[0094] In transmission modes where the UE performs sidelink resource selection and / or scheduling (e.g., mode 2 resource allocation), periodic and aperiodic resource reservations can be supported. As mentioned above, the UE can send a sidelink resource reservation to reserve resources for one or more communications performed by the UE. Aperiodic resource reservations can reserve a single resource or a group of resources (e.g., without defined periodicity). Periodic resource reservations can reserve a series of resources at least in part based on periodicity. For aperiodic resource reservations, the UE can (e.g., via SCI-1) signal the time and frequency (time / frequency) resources used for transmissions and up to two future transmissions. In addition to the priority and / or periodicity associated with the reservation, periodic resource reservations may also include information similar to that included in aperiodic resource reservations (e.g., time / frequency resources for one or more transmissions).

[0095] In some cases, resource reservation can reserve resources that include both sidelink time slots and SBFD time slots. For example, a single reserved resource allocation may include both sidelink time slots and SBFD time slots. As another example, a first resource allocation reserved by resource reservation may include sidelink time slots, and a second resource allocation reserved by resource reservation may include SBFD time slots (and vice versa). As yet another example, a sidelink resource pool configured for a UE may include both sidelink time slots and SBFD time slots. However, as mentioned above, uplink time slots may be associated with bandwidths different from those associated with SBFD time slots. Therefore, uplink time slots and SBFD time slots may be associated with different numbers of subchannels. Since sidelink resource reservation can identify the frequency allocation of reserved resources by referring to one or more subchannel indices, ambiguity may arise regarding how to interpret resource reservation for a frequency band or sidelink resource pool that includes uplink time slots and SBFD time slots. This ambiguity may reduce the bandwidth that can be effectively resolved, hinder UE sidelink communication, and reduce throughput.

[0096] Some of the techniques and apparatus described herein provide signaling for sidelink resource reservation across one or more uplink time slots and one or more smaller bandwidth time slots (such as SBFD time slots). For example, some of the techniques and apparatus described herein provide a common subchannel index configuration for uplink time slots and smaller bandwidth time slots in a given frequency band or a given sidelink resource pool. Therefore, a single sidelink resource reservation can indicate frequency resource allocation on uplink time slots and smaller bandwidth time slots such as SBFD time slots, thereby eliminating ambiguity regarding sidelink resource reservation and improving bandwidth that can be efficiently resolved. Furthermore, the common subchannel index configuration reduces overhead compared to configuring different subchannel index configurations for each time slot type in the resource pool. Some of the techniques and apparatus described herein provide interpretations of sidelink resource reservations such as those by a transmitting UE reserving resources for transmitting or by a receiving UE reserving resources for receiving, or in consideration of one or more invalid frequency resources (e.g., one or more frequency resources, such as subchannels that are unavailable for reserved SBFD time slots). In this way, bandwidth that can be efficiently resolved is increased, facilitating UE sidelink communication and improving throughput.

[0097] Figure 7This is a diagram illustrating example 700 of signaling associated with sidelink resource scheduling according to this disclosure. As shown, example 700 includes a first UE (e.g., UE 120, UE 305, UE 405), a second UE (e.g., UE 120, UE 305, UE 410), and a network entity (e.g., BS110). In example 700, "uplink slot" refers to a slot that is semi-statically configured as an uplink slot, or a slot that is semi-statically configured with at least a threshold number of uplink symbols. Typically, and depending on the context, "resource" and "slot" are used interchangeably in example 700. Dashed arrows and boxes indicate optional steps.

[0098] Figure 7 The operations (and other descriptions herein) are described in the context of SBFD resources. However, these operations can be applied to any kind of smaller bandwidth resource. A smaller bandwidth resource is a resource associated with a smaller bandwidth than another resource, such as a baseline resource (e.g., a resource that occupies the entire bandwidth, such as a component carrier or a portion of the bandwidth), another resource pool that includes a smaller bandwidth resource, etc. For example, an example of a smaller bandwidth resource is an SBFD resource, which is associated with a smaller bandwidth than an uplink resource.

[0099] like Figure 7 As shown by reference numeral 705 in the accompanying drawings, a network entity can provide the UE with information indicating one or more SBFD resources (i.e., one or more smaller bandwidth resources). For example, the network entity can provide information indicating one or more SBFD time slots. In some aspects, the information indicating one or more SBFD time slots can be provided via Radio Resource Control (RRC) signaling, Media Access Control (MAC) signaling, Downlink Control Information (DCI), etc. In some aspects, the information indicating one or more SBFD time slots can be provided semi-statically. The information indicating one or more SBFD time slots can identify one or more SBFD time slots and can indicate one or more downlink portions, one or more uplink portions, and / or one or more gap portions of the SBFD time slots. In some aspects, the information indicating one or more SBFD time slots can further indicate which time slots are uplink time slots, which time slots are downlink time slots, etc. In some aspects, the one or more SBFD time slots can be one or more semi-static SBFD time slots, such as SBFD time slots indicated via semi-static signaling.

[0100] As shown by reference numeral 710 in the attached figure, a network entity may provide the UE with information indicating multiple resources (e.g., time / frequency resources) that indicate a resource pool (e.g., a sidelink resource pool) associated with sidelink communication. For example, the network entity may provide the UE with a resource pool configuration. The resource pool configuration may include the above-mentioned combination... Figure 6At least a portion of the described information. In some aspects, the information indicated by reference numeral 710 may relate to a single resource pool. In other aspects, the information indicated by reference numeral 710 may relate to multiple resource pools. As shown, the information may indicate multiple resources within a resource pool. For example, a network entity may identify multiple resources.

[0101] In some aspects, the UE may be pre-configured with at least a portion of the information shown by reference numerals 705 and 710.

[0102] As shown by reference numeral 715 in the attached figure, the first UE may transmit sidelink resource reservations. For example, the first UE may transmit sidelink resource reservations via sidelink control information (such as SCI-1). Sidelink resource reservations may indicate one or more resources in the first UE's resource pool. For example, sidelink resource reservations may indicate time resources (e.g., time slots, symbol groups, time slot sets) and frequency resources (e.g., one or more subcarrier indices corresponding to one or more subcarriers) for at least one transmission. In some aspects, sidelink resource reservations may be periodic resource reservations, in which case the sidelink resource reservation may identify the periodicity of the reserved resources and / or the priority of the reserved resources. In other aspects, sidelink resource reservations may be non-periodic resource reservations.

[0103] In some aspects, sidelink resource reservation can identify resources in a first time slot and a second time slot, where the first time slot is configured as an uplink time slot and the second time slot is configured as an SBFD time slot. The first time slot can be before or after the second time slot. Alternatively or additionally, the resource pool of the first UE can include resources in both the first and second time slots. In such a case, the bandwidth of the first time slot can be different from the bandwidth of the second time slot, and therefore the first and second time slots can be associated with different numbers of subchannels. Furthermore, since some subchannels in the second time slot are associated with resources that are not semi-statically configured as uplink resources, these subchannels can be considered invalid for the resource pool or sidelink resource reservation. The first UE, the second UE, and / or the base station can use the same index configuration for the first and second time slots to eliminate ambiguity regarding resource reservations on the first and second time slots. For example, it can be practically assumed that the total number of subchannels is the same in different time slots. Therefore, the subchannel indices also remain the same.

[0104] As described above, periodic resource reservation can be associated with periodicity. Periodicity can indicate the length of time between resources reserved by periodic resource reservation. For example, periodicity can indicate a first resource (or a first set of resources) used for one or more transmissions, and can indicate the periodicity at which the first resource will recur. The resources reserved by periodic resource reservation may be referred to herein as periodic reservations, and can indicate multiple repetitions of periodic reservations (e.g., with a period associated with the periodic resource reservation). In some cases, periodic reservations can be associated with a periodicity different from the periodicity of SBFD slots in the resource pool, meaning that some periodic reservations may occur in SBFD slots containing at least one invalid frequency resource, while other periodic reservations may occur in non-SBFD slots (e.g., uplink slots). In some aspects, a first UE can determine periodic resource reservations such that repetitions of periodic reservations do not include invalid frequency resources in any SBFD slots. For example, when reserving resources for current and future transmissions, the first UE can ensure that the indicated PSCCH / PSSCH resources are not periodically on invalid frequency resources. The first UE's selection of resources to avoid invalid frequency resources can reduce the processing resource usage at the second UE, which would otherwise be used to identify invalid frequency resources and interpret sidelink resource reservations at least in part based on invalid frequency resources.

[0105] In some respects, the second UE may assume that the first UE does not transmit repetitions of periodic reservations occurring in invalid frequency resources within the SBFD time slot. For example, periodic resource reservations may indicate one or more resources appearing in invalid frequency resources within the SBFD time slot. The second UE may assume that the first UE does not transmit on the indicated one or more resources. The second UE's determination of invalid frequency resources and its interpretation of sidelink resource reservations based at least in part on invalid frequency resources can simplify and improve the flexibility of resource reservations for the first UE.

[0106] In some respects, if a periodic reservation fully or partially overlaps with at least one invalid frequency resource, the second UE can assume that the transmission associated with the periodic reservation has not occurred. For example, if a repetition of a periodic reservation fully or partially overlaps with at least one invalid frequency resource, the first UE can choose not to transmit that repetition. As another example, if the indicated PSCCH / PSSCH fully or partially overlaps with an invalid frequency resource in the SBFD slot, the second UE can assume that no transmission has occurred, which simplifies decoding at the second UE.

[0107] In other respects, transmissions associated with periodic reservations can occur on indicated resources that do not overlap with invalid frequency resources. For example, a first UE can transmit communication without using invalid frequency resources in the SBFD slot. As another example, transmissions can occur on a portion of the indicated PSCCH / PSSCH resources that does not overlap with invalid symbols or sub-channels of the SBFD slot or invalid sub-channels of the indicated PSSCH, which improves the resource utilization and efficiency of sidelink communication. As a more specific example, the indicated PSSCH may contain 5 sub-channels, 2 of which overlap with the set of invalid frequency resources. In this case, even if the first UE signals transmissions on 5 sub-channels, the first UE also transmits on 3 sub-channels that do not overlap with the set of invalid frequency resources. The second UE can perform decoding on the 3 sub-channels that do not overlap with the set of invalid frequency resources. When transmission and decoding are performed only on valid sub-channels of the SBFD slot, sidelink resource reservations can be referred to as truncated allocation.

[0108] In some aspects, when the first UE and / or the second UE truncates the allocation of sidelink resource reservations, the first UE and / or the second UE can use the original (e.g., complete, untrunculated) bandwidth of the sidelink resource reservations in subsequent periodic reservations. For example, the PSSCH indicated in the first time slot (e.g., the SBFD time slot) may contain 5 sub-channels, of which 2 sub-channels overlap with a set of invalid frequency resources. In this case, the first UE transmits on the 3 sub-channels that do not overlap with the set of invalid frequency resources, and the second UE decodes on the 3 sub-channels that do not overlap with the set of invalid frequency resources. In the second time slot (e.g., the uplink time slot), after the first time slot, all 5 sub-channels are valid for sidelink communication. In the second time slot, the first UE transmits on all 5 sub-channels of the indicated PSSCH, and the second UE decodes on all 5 sub-channels of the indicated PSSCH.

[0109] In some aspects, when a first UE and / or a second UE truncates the allocation of sidelink resource reservations, the first UE and / or the second UE can continue to use the truncated resource allocations (e.g., reduced bandwidth of sidelink resource reservations) in subsequent periodic reservations. For example, the PSSCH indicated in a first time slot (e.g., an SBFD time slot) may contain five sub-channels, two of which overlap with a set of invalid frequency resources. In this case, the first UE transmits on three sub-channels that do not overlap with the set of invalid frequency resources, and the second UE decodes on three sub-channels that do not overlap with the set of invalid frequency resources. In a second time slot (e.g., an uplink time slot), after the first time slot, all five sub-channels are valid for sidelink communication. In the second time slot, the first UE transmits only on the three sub-channels in the first time slot that do not overlap with the set of invalid frequency resources, and the second UE decodes only on the three sub-channels in the first time slot that do not overlap with the set of invalid frequency resources. This allows other sensing UEs to detect authorization in the first time slot and determine the reservation of only three sub-channels that do not overlap with the set of invalid frequency resources (thereby enabling other sensing UEs to use the set of invalid frequency resources for communication).

[0110] As shown by reference numeral 720 in the attached figure, the second UE can receive sidelink resource reservations. In some aspects, the second UE can identify one or more invalid frequency resources in the SBFD time slot associated with the sidelink resource reservation. In some aspects, the second UE can truncate one or more periodic reservations based at least in part on the overlap between one or more periodic reservations of the sidelink resource reservation and invalid frequency resources in the SBFD time slot. For example, as described above, the second UE can determine to decode the first UE's transmission only on one or more valid sub-channels of the SBFD time slot.

[0111] As shown by reference numeral 725, a first UE can transmit one or more communications at least partially based on sidelink resource reservation, and a second UE can decode one or more communications at least partially based on sidelink resource reservation. For example, the first UE can transmit one or more communications on one or more resources (e.g., periodic or aperiodic resources) reserved by sidelink resource reservation. In some aspects, the first and second UEs can, for example, truncate one or more resources at least partially based on the overlap of one or more resources with invalid frequency resources in the SBFD time slot. If one or more resources are truncated in the SBFD time slot, subsequent communications can use the original bandwidth of the one or more resources (before truncation) or the truncated bandwidth of the one or more resources, as described above. In this way, ambiguity in sidelink resource reservation of a resource pool including one or more SBFD time slots is reduced, throughput is improved, and the versatility of sidelink resource reservation is enhanced.

[0112] As mentioned above, Figure 7 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 7 The examples described are different.

[0113] Figure 8 This is a diagram illustrating example 800 of a subchannel index associated with sidelink resource scheduling according to this disclosure. Example 800 shows a first time slot and a second time slot. The first time slot is an uplink time slot, meaning that the first time slot is semi-statically configured as an uplink time slot or semi-statically configured with at least a threshold number of uplink signals. The second time slot is an SBFD time slot, meaning that the second time slot is semi-statically configured as an SBFD time slot. Valid subchannels are indicated by white fill, and invalid frequency resources are indicated by diagonal fill. As described above, such as when valid subchannels are semi-statically configured as uplink resources at least in part, valid subchannels are subchannels available for sidelink communication. As described above, such as when invalid frequency resources are dynamically configured as uplink or downlink, or semi-statically configured as downlink, invalid frequency resources are subchannels unavailable for sidelink communication.

[0114] As shown in the figure, the sidelink resource pool in the first time slot includes sub-channels 0, 1, 2, and 3. Therefore, the first time slot has a first bandwidth available for sidelink resource reservation. However, in the second time slot, only two sub-channels are valid. Therefore, the second time slot has a second bandwidth available for sidelink resource reservation. Invalid frequency resources can be considered to be within the first bandwidth (because invalid frequency resources are valid in the first time slot), rather than within the second bandwidth (because invalid frequency resources are invalid in the second time slot). Invalid frequency resources can be considered invalid for transmissions reserved for sidelink resources, meaning that the first UE can determine not to schedule and / or transmit communication on invalid frequency resources, or the second UE can determine not to decode communication on invalid frequency resources.

[0115] As described elsewhere in this document, the techniques and apparatus described herein enable the use of a common subchannel index for both the first and second time slots. The common subchannel index configuration means that the same subchannel index as in the SBFD time slot is assigned to a subchannel occupying a given bandwidth in the uplink time slot. In other words, a given subchannel in a given resource pool has the same index, regardless of the time slot type (e.g., whether the time slot including the given subchannel is an SBFD time slot or an uplink time slot). Therefore, ambiguity in the subchannel indication of the second time slot is eliminated. For example, without the common subchannel index, it might be unclear whether the sidelink resource reservation indicating subchannel index #0 in the first and second time slots refers to the subchannel indicated by reference numeral 810 or the subchannel indicated by reference numeral 820.

[0116] As mentioned above, Figure 8 This is provided as an example. Other examples may be provided in conjunction with [the example provided]. Figure 8 The examples described are different.

[0117] Figure 9 This is a diagram illustrating an exemplary process 900 performed, for example, by a UE according to this disclosure. Example process 900 is wherein a UE (e.g., UE 120, UE 305, UE 405, ...) is involved. Figure 7 Examples of the first UE include using the common subchannel index configuration to perform operations associated with sidelink resource scheduling.

[0118] like Figure 9 As shown, in some aspects, process 900 may include transmit sidelink resource reservation, wherein the sidelink resource reservation indicates a first resource in an uplink timeslot having a first bandwidth available for sidelink resource reservation and a second resource in a smaller bandwidth timeslot having a second bandwidth available for sidelink resource reservation, and wherein the sidelink resource reservation uses the same subchannel index configuration for the uplink timeslot and the smaller bandwidth timeslot (box 910). For example, the UE (e.g., using...) Figure 11 The transmitting component 1104 or scheduling component 1108 depicted can transmit sidelink resource reservations, wherein the sidelink resource reservation indicates a first resource in an uplink time slot having a first bandwidth available for the sidelink resource reservation and a second resource in a smaller bandwidth time slot having a second bandwidth available for the sidelink resource reservation, and wherein the sidelink resource reservation uses the same subchannel index configuration for the uplink time slot and the smaller bandwidth time slot, as described above. In some aspects, the sidelink resource reservation can indicate resources in either an uplink time slot or a smaller bandwidth time slot, and can use the same subchannel index configuration for both. For example, a resource pool can include uplink time slots and smaller bandwidth time slots, and can use the same subchannel index configuration.

[0119] like Figure 9 As further shown, in some aspects, process 900 may include using sidelink resource reservation to send communication (block 920). For example, the UE (e.g., using...)

[0121] In the first aspect, one or more invalid frequency resources in a smaller bandwidth time slot that are included in the first bandwidth but not in the second bandwidth are considered invalid for transmissions reserved for sidelink resources.

[0122] In a second aspect, either alone or in combination with the first aspect, the second resource is not in the invalid frequency resources of the smaller bandwidth time slot, wherein the invalid frequency resources are in the first bandwidth but not in the second bandwidth, based at least in part on the SBFD configuration of the smaller bandwidth time slot.

[0130] Figure 10 This is a diagram illustrating an exemplary process 1000 performed, for example, by a UE according to this disclosure.

For example, the UE (e.g., using...) Figure 12 The receiving component 1202 depicted can receive sidelink resource reservations, wherein the sidelink resource reservations indicate a first resource in an uplink timeslot having a first bandwidth available for the sidelink resource reservations and a second resource in a smaller bandwidth timeslot having a second bandwidth available for the sidelink resource reservations, and wherein the sidelink resource reservations use the same subchannel index configuration for the uplink timeslots and the smaller bandwidth timeslots, as described above.

[0132] like Figure 10 As further shown, in some aspects, process 1000 may include decoding communication at least in part based on sidelink resource reservation (block 1020).

[0139] In the sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the decoding of repetitions involving invalid frequency resources is performed without using invalid frequency resources.

[0140] In the seventh aspect, either alone or in combination with one or more of the first to sixth aspects, the repetition is the first repetition, and the second repetition that occurs after the first repetition utilizes the full bandwidth reserved for sidelink resources.
