[0004] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephony, video, data, messaging, broadcasts, or other similar types of services. These wireless communication systems may employ multiple-access technologies capable of supporting communications with multiple users by sharing available wireless communication system resources with those users.

[0005] While wireless communication systems have made tremendous technological advances over the years, challenges remain.

[0026] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for transmitting parameters for a portion of a sidelink resource pool.

[0027] Wireless communication devices, such as user equipment (UE), can communicate with each other without the direct involvement of a network entity, such as a gNB. Between UEs, such direct communication may be referred to as sidelink communication. Sidelink communication may occur over a configured set of time and frequency resources, referred to as a sidelink resource pool (sometimes referred to as a resource pool). UEs performing sidelink communication may be referred to as sidelink UEs. Some sidelink UEs may be considered baseline (e.g., normal enhanced mobile broadband) UEs, while other sidelink UEs may be associated with reduced capabilities (referred to herein as UEs with threshold capabilities). UEs with threshold capabilities are capable of using or are configured to use a smaller communication bandwidth than baseline UEs. In some examples, the bandwidth of the sidelink resource pool may exceed the communication bandwidth of UEs with threshold capabilities. It may be beneficial to configure a portion of the sidelink resource pool (e.g., an appropriate subset of the bandwidth of the sidelink resource pool) for communication by UEs with threshold capabilities.

[0028] However, a threshold-capable UE may have different communication capabilities than a baseline UE, and the transmit parameters of the sidelink resource pool may be configured at the granularity of the entire sidelink resource pool. If the transmit parameters of the sidelink resource pool are configured at the granularity of the sidelink resource pool, the capabilities of the threshold-capable UE may be exceeded, resulting in suboptimal performance of the threshold-capable UE. For example, a threshold-capable UE may have a lower interference mitigation capability or transmit power than a baseline UE. If the baseline UE communicates in a portion of the sidelink resource pool configured for the threshold-capable UE using transmit power parameters configured across the entire sidelink resource pool, the lower capability of the threshold-capable UE may result in increased interference to the UE's communications and reduced effectiveness of the UE's communications.

[0029] Some techniques described herein provide for configuring transmit parameters for a portion of a sidelink resource pool. By configuring transmit parameters for a portion of a sidelink resource pool (rather than the entire sidelink resource pool), the capabilities of threshold-capable UEs (for which a portion of the sidelink resource pool may be configured for communication) may be taken into account, thereby improving performance for such UEs. For example, the transmit parameters may indicate power control parameters that may be used by a baseline UE when communicating in a portion of the sidelink resource pool. The power control parameters may cause the baseline UE to use lower transmit power in a portion of the sidelink resource pool than in a remaining portion of the sidelink resource pool, thereby reducing interference to threshold-capable UEs and improving the effectiveness of communications for such UEs (without having to increase the transmit power of such UEs).

[0030] 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 construed as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It will be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. Furthermore, the scope of the present disclosure is intended to encompass such devices or methods implemented using other structures, functions, or structures and functions in addition to or different from the various aspects of the 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.

[0031] 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, or algorithms (collectively, "elements"). These elements can 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.

[0032] Although various aspects may be described herein using terminology generally associated with 5G or New Radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G (e.g., 6G) RATs.

[0033] Figure 1 An example of a wireless communication network 100 is depicted.

[0034] Generally speaking, the wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). A network entity is typically a communication device and / or a communication function performed by a communication device (e.g., a UE, a base station (BS), a component of a BS, a server, etc.). For example, various functions of a network and various devices associated with and interacting with the network can be considered network entities. In addition, the wireless communication network 100 includes terrestrial aspects, such as ground-based network entities (e.g., BS 110), and non-terrestrial aspects, such as satellites 140 and aircraft 145. The non-terrestrial aspects may include airborne network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., ground BSs) and UEs.

[0035] In the depicted example, the wireless communication network 100 includes a BS 110, a UE 120, and one or more core networks (such as an evolved packet core (EPC) 160 and a 5G core (5GC) 190) that interoperate to provide communication services over various communication links (including wired and wireless links).

[0036] Figure 1Various example UEs 120 are depicted, which may include a cellular phone, a smartphone, a Session Initiation Protocol (SIP) phone, a laptop computer, a personal digital assistant (PDA), a satellite radio, a global positioning system (GPS), a multimedia device, a video device, a digital audio player, a camera, a game console, a tablet computer, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, an Internet of Things (IoT) device, an always-on (AON) device, an edge processing device, or another similar device. A UE 120 may also be referred to as a mobile device, a wireless device, a wireless communication device, a station, a mobile station, a subscriber station, a mobile subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, or a handset, among others.

[0037] BS 110 may communicate wirelessly with UE 120 (e.g., transmit signals to or receive signals from the UE) via communication link 170. Communication link 170 between BS 110 and UE 120 may carry uplink (UL) (also known as a reverse link) transmissions from UE 120 to BS 110 and / or downlink (DL) (also known as a forward link) transmissions from BS 110 to UE 120. In various aspects, communication link 170 may utilize multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity.

[0038] BS 110 may include, for example, a NodeB, an enhanced NodeB (eNB), a next-generation enhanced NodeB (ng-eNB), a next-generation NodeB (gNB or gNodeB), an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a transmit / receive point, etc. BS 110 may provide communication coverage for a corresponding geographic coverage area 112, which may sometimes be referred to as a cell and which may overlap in some cases (e.g., a small cell provided by BS 110a may have a coverage area 112' that overlaps with the coverage area 112 of a macro cell). For example, BS 110 may provide communication coverage for a macro cell (covering a relatively large geographic area), a pico cell (covering a relatively small geographic area, such as a stadium), a femto cell (covering a relatively small geographic area (e.g., a home)), and / or other types of cells.

[0039] Although BS110 is depicted as a single communication device in various aspects, BS110 can be implemented in various configurations. For example, to give a few examples, one or more components of the base station may be decomposed, including a central unit (CU), one or more distributed units (DUs), one or more radio units (RUs), a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC. In another example, various aspects of the base station may be virtualized. More generally, a BS (e.g., BS110) may include components located at a single physical location or components located at various physical locations. In an example where the BS includes components located at various physical locations, the various components may each perform a function such that the various components together implement functions similar to a BS located at a single physical location. In some aspects, a BS including components located at various physical locations may be referred to as having a decomposed radio access network architecture, such as an open RAN (O-RAN) architecture or a virtualized RAN (VRAN) architecture. Figure 3 An example decomposed BS architecture is depicted and described.

[0040] Different BSs 110 within the wireless communication network 100 may also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G, etc.). For example, a BS 110 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interact with the EPC 160 via a first backhaul link 132 (e.g., an S1 interface). A BS 110 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) may interact with the 5GC 190 via a second backhaul link 184. The BSs 110 may communicate with each other directly or indirectly (e.g., via the EPC 160 or the 5GC 190) via a third backhaul link 134 (e.g., an X2 interface), which may be wired or wireless.

[0041] The wireless communication network 100 may subdivide the electromagnetic spectrum into various categories, frequency bands, channels, or other characteristics. In some aspects, the subdivisions are based on wavelength and frequency, where frequency may also be referred to as a carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines Frequency Range 1 (FR1) as comprising 410 MHz to 7125 MHz, which is often (interchangeably) referred to as "sub-6 GHz." Similarly, 3GPP currently defines Frequency Range 2 (FR2) as comprising 24,250 MHz to 52,600 MHz, which is sometimes (interchangeably) referred to as "millimeter wave" ("mmW" or "mmWave"). A base station configured to communicate using mmWave or near-mmWave radio bands (e.g., a mmWave base station such as BS110b) may utilize beamforming (e.g., as shown by 182) with a UE (e.g., 120) to improve path loss and range.

[0042] The communication link 170 between the BS 110 and, for example, the UE 120 may be over one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, and / or other bandwidths) and may be aggregated in various ways. The carriers may or may not be adjacent to each other. In some examples, the allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL).

[0043] Communications using higher frequency bands may have higher path loss and shorter range than communications using lower frequencies. Accordingly, some base stations (e.g., Figure 1182 . BS 110b and UE 120 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming. In some cases, BS 110b may transmit beamformed signals to UE 120 in one or more transmit directions 182 ′. UE 120 may receive beamformed signals from BS 110b in one or more receive directions 182 ″. UE 120 may also transmit beamformed signals to BS 110b in one or more transmit directions 182 ″. BS 110b may also receive beamformed signals from UE 120 in one or more receive directions 182 ′. BS 110b and UE 120 may then perform beam training to determine optimal receive and transmit directions for each of BS 110b and UE 120. Note that the transmit and receive directions of BS 110b may or may not be the same. Similarly, the transmit direction and receive direction of UE 120 may or may not be the same.

[0044] The wireless communication network 100 also includes a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, the 2.4 GHz and / or 5 GHz unlicensed spectrum.

[0045] Some of the UEs 120 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and / or a physical sidelink feedback channel (PSFCH).

[0046] EPC 160 may include various functional components, including: a mobility management entity (MME) 161, other MMEs 162, a serving gateway 163, a multimedia broadcast multicast service (MBMS) gateway 164, a broadcast multicast service center (BM-SC) 165, and / or a packet data network (PDN) gateway 166, such as in the depicted example. MME 161 may communicate with a home subscriber server (HSS) 167. MME 161 is a control node that handles signaling between UE 120 and EPC 160. Generally speaking, MME 161 provides bearer and connection management.

[0047] Generally, user Internet Protocol (IP) packets are delivered through a serving gateway 163, which is connected to a PDN gateway 166. The PDN gateway 166 provides UE IP address allocation and other functions. The PDN gateway 166 and the BM-SC 165 are connected to IP services 168, which may include, for example, the Internet, an intranet, an IP multimedia subsystem (IMS), packet-switched (PS) streaming services, and / or other IP services.

[0048] BM-SC 165 can provide functionality for MBMS user service provisioning and delivery. BM-SC 165 can serve as the entry point for content providers' MBMS delivery, can be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and / or can be used to schedule MBMS delivery. MBMS Gateway 164 can distribute MBMS services to BSs 110 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a specific service, and / or can be responsible for session management (start / stop) and collecting eMBMS-related billing information.

[0049] 5GC 190 may include various functional components, including: access and mobility management function (AMF) 191, other AMFs 192, session management function (SMF) 193, and user plane function (UPF) 194. AMF 191 may communicate with unified data management (UDM) 195.

[0050] AMF 191 is a control node that processes signaling between UE 120 and 5GC 190. AMF 191 provides, for example, Quality of Service (QoS) flow and session management.

[0051] The IP packets are passed through UPF 194, which connects to IP services 196 and provides UE IP address allocation and other functions for 5GC 190. IP services 196 may include, for example, the Internet, intranet, IMS, PS streaming services, and / or other IP services.

[0052] In various aspects, a network entity or network node may be implemented as a converged base station, a decomposed base station, a component of a base station, an integrated access and backhaul (IAB) node, a relay node, a sidelink node, a transmit receive point (TRP), or a combination thereof, to name a few examples.

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

[0054] Figure 2 Aspects of an example BS 110 and UE 120 are depicted.

[0055] Generally speaking, BS 110 includes various processors (e.g., 220, 230, 238, and 240), antennas 234a-234t (collectively 234), transceivers 232a-232t (collectively 232) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., data source 212) and wireless reception of data (e.g., data sink 239). For example, BS 110 can transmit and receive data between BS 110 and UE 120. BS 110 includes a controller / processor 240 that can be configured to implement various functions described herein related to wireless communication.

[0056] Generally speaking, the UE 120 includes various processors (e.g., 258, 264, 266, and 280), antennas 252a-252r (collectively, 252), transceivers 254a-254r (collectively, 254) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., retrieved from a data source 262) and wireless reception of data (e.g., provided to a data sink 260). The UE 120 includes a controller / processor 280 that can be configured to implement various functions described herein related to wireless communications.

[0057] For example downlink transmissions, BS 110 includes a transmit processor 220 that can receive data from a data source 212 and control information from a controller / processor 240. The control information can be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid automatic repeat request (HARQ) indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), and / or other channels. In some examples, the data can be for a physical downlink shared channel (PDSCH).

[0058] The transmit processor 220 may process the data and control information (e.g., encode and symbol map) to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols such as those for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), or a channel state information reference signal (CSI-RS).

[0059] The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols, as applicable, and may provide an output symbol stream to a modulator (MOD) in transceivers 232a-232t. Each modulator in transceivers 232a-232t may process a corresponding output symbol stream to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators in transceivers 232a-232t may be transmitted via antennas 234a-234t, respectively.

[0060] UE 120 includes antennas 252a-252r that can receive downlink signals from BS 110 and provide received signals to demodulators (DEMODs) in transceivers 254a-254r, respectively. Each demodulator in transceivers 254a-254r can condition (e.g., filter, amplify, downconvert, and digitize) a corresponding received signal to obtain input samples. Each demodulator can further process the input samples to obtain received symbols.

[0061] A MIMO detector 256 may obtain received symbols from all demodulators in transceivers 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information to a controller / processor 280.

[0062] For example uplink transmissions, the UE 120 also includes a transmit processor 264 that can receive and process data from a data source 262 (e.g., for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 280 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 264 can also generate reference symbols for reference signals (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266, if applicable, further processed by the modulators in the transceivers 254a-254r (e.g., for SC-FDM), and transmitted to the BS 110.

[0063] At BS 110, uplink signals from UE 120 may be received by antennas 234a-234t, processed by demodulators in transceivers 232a-232t, 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 the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. Memory 242 and memory 282 may store data and program codes (e.g., processor-executable instructions, computer-executable instructions) for BS 110 and UE 120, respectively. Scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.

[0064] In various aspects, the BS 110 may be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, "transmitting" may refer to various mechanisms for outputting data, such as from a data source 212, a scheduler 244, a memory 242, a transmit processor 220, a controller / processor 240, a TX MIMO processor 230, transceivers 232a-232t, antennas 234a-234t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as from antennas 234a-234t, transceivers 232a-232t, an RX MIMO detector 236, a controller / processor 240, a receive processor 238, a scheduler 244, a memory 242, a network interface, and / or other aspects described herein.

[0065] In various aspects, the UE 120 may also be described as transmitting and receiving various types of data associated with the methods described herein. In these contexts, "transmitting" may refer to various mechanisms for outputting data, such as from a data source 262, memory 282, transmit processor 264, controller / processor 280, TX MIMO processor 266, transceivers 254a-254t, antennas 252a-252t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as from antennas 252a-252t, transceivers 254a-254t, RX MIMO detector 256, controller / processor 280, receive processor 258, memory 282, and / or other aspects described herein.

[0066] In some aspects, the processor may be configured to perform various operations, such as those associated with the methods described herein, and send (output) data to or receive (obtain) data from another interface configured to send or receive data, respectively.

[0067] Although Figure 2 The blocks in FIG. 2 are illustrated as distinct components, but the functionality described above with respect to 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.

[0068] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0069] The deployment of a communication system such as a 5G NR system can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of the network, a RAN node, a core network node, a network element, a base station or network equipment may be implemented in an aggregated architecture or a decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) performing base station functions may be implemented as an aggregated base station (also known as an independent base station or a monolithic base station) or a decomposed base station. A “network entity” or a “network node” may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs or a combination thereof).

[0070] A converged base station (e.g., a converged network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually spread across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of the CUs, DUs, and RUs may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among others.

[0071] Base station type operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scaling of the communication system by separating base station functionality into one or more units that can be deployed separately. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Each unit of the disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0072] Figure 3 An example disaggregated base station 300 architecture is depicted. The disaggregated base station 300 architecture may include one or more central units (CUs) 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 325 via an E2 link, or a non-real-time (non-RT) RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CUs 310 may communicate with one or more distributed units (DUs) 330 via corresponding midhaul links, such as an F1 interface. The DUs 330 may communicate with one or more radio units (RUs) 340 via corresponding fronthaul links. The RUs 340 may communicate with corresponding UEs 120 via one or more radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0073] Each of the units (e.g., CU 310, DU 330, RU 340, and near-RT RIC 325, non-RT RIC 315, and SMO framework 305) may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of these units, or an associated processor or controller that provides instructions to the communication interface of the unit, may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium. Additionally or alternatively, these units may include a wireless interface that may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more of the other units via a wireless transmission medium, or both.

[0074] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), or service data adaptation protocol (SDAP), among others. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functions (e.g., central unit-user plane (CU-UP)), control plane functions (e.g., central unit-control plane (CU-CP)), or a combination thereof. In some implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0075] The DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more higher physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, or modulation and demodulation), at least in part according to a functional split, such as that defined by the Third Generation Partnership Project (3GPP). In some aspects, the DU 330 may also host one or more lower PHY layers. Each layer (or module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0076] Lower layer functions may be implemented by one or more RUs 340. In some deployments, a RU 340 controlled by a DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, or Physical Random Access Channel (PRACH) extraction and filtering), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 340 may be implemented to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, both real-time and non-real-time aspects of control and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable the DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0077] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as Open Cloud (O-Cloud) 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, and near-RT RIC 325. In some implementations, the SMO framework 305 can communicate with hardware aspects of the 4G RAN (such as Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with one or more RUs 340 via the O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305 .

[0078] The non-RT RIC 315 can be configured to include logic that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 can be configured to include logic that enables near-real-time control and optimization of RAN elements and resources through data collection and actions over an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0079] In some implementations, the non-RT RIC 315 can receive parameters or external enrichment information from an external server to generate an AI / ML model to be deployed in the near-RT RIC 325. Such information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or from network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of O1) or by creating RAN management policies (such as A1 policies).

[0080] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0081] Figure 4A 、 Figure 4B 、 Figure 4C and Figure 4D Describes a method for use in wireless communication networks such as Figure 1 Various aspects of the data structure of the wireless communication network 100). Figure 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5G NR) frame structure, Figure 4B is a diagram 430 illustrating an example of a DL channel within a 5G subframe, Figure 4C is a diagram 450 illustrating an example of a second subframe within a 5G frame structure, and Figure 4D FIG480 is a diagram illustrating an example of UL channels within a 5G subframe.

[0082] Wireless communication systems can utilize Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on both the uplink and downlink. Such systems can also support half-duplex operation using Time Division Duplex (TDD). OFDM and Single Carrier Frequency Division Multiplexing (SC-FDM) will (for example, Figure 4B and Figure 4D The system bandwidth (as depicted in FIG) is divided into multiple orthogonal subcarriers. Each subcarrier can be modulated with data. Modulation symbols can be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0083] The wireless communication frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to either DL or UL. The wireless communication frame structure may also be time division duplex (TDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to both DL and UL.

[0084] exist Figure 4A and Figure 4C In the embodiment of the present invention, the wireless communication frame structure is TDD, where D is DL, U is UL, and F is flexibly used between DL / UL. The UE can be configured with a time slot format (dynamically configured by DL control information (DCI) or semi-statically / statically configured by RRC signaling) through a received time slot format indicator (SFI). In the depicted example, the 10ms frame is divided into 10 equally sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. The subframe may also include micro-slots, which typically have fewer symbols than a whole time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0085] In certain aspects, the number of slots within a subframe is based on the slot configuration and the numerology. For example, for slot configuration 0, different numerologies (μ) 0 through 5 allow for 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different numerologies 0 through 2 allow for 2, 4, and 8 slots per subframe, respectively. Accordingly, for slot configuration 0 and numerology μ, there are 14 symbols per slot and 2 per subframe. μ time slots. The subcarrier spacing and symbol length / duration are functions of the parameter set. The subcarrier spacing can be equal to 2 μ × 15 kHz, where μ is the parameter set index, which can be selected from values ​​0 to 5. Thus, the subcarrier spacing for parameter set μ = 0 is 15 kHz, and the subcarrier spacing for parameter set μ = 5 is 480 kHz. Other parameter sets and subcarrier spacings can be used. The symbol length / duration is inversely related to the subcarrier spacing. Figure 4A 、 Figure 4B 、 Figure 4C and Figure 4D An example is provided for slot configuration 0 with 14 symbols per slot and parameter set μ = 2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0086] like Figure 4A 、 Figure 4B 、 Figure 4C and Figure 4D As depicted in FIG, a resource grid can be used to represent the frame structure. Each time slot includes a resource block (RB) (also called a physical RB (PRB)) extending over, for example, 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0087] like Figure 4A As illustrated, some of the REs carry reference (pilot) signals (RSs) for a UE (e.g., UE 120). The RSs may include demodulation RSs (DMRSs) and / or channel state information reference signals (CSI-RSs) for channel estimation at the UE. The RSs may also include beamforming RSs (BRSs), beam refinement RSs (BRRSs), and / or phase tracking RSs (PT-RSs).

[0088] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated. The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE Groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0089] A primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of a frame. The PSS is used by a UE (eg, UE 120) to determine subframe / symbol timing and physical layer identification.

[0090] A Secondary Synchronization Signal (SSS) may be within symbol 4 of a specific subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing.

[0091] Based on the physical layer identifier and the physical layer cell identifier group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (SSB). The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information not sent via the PBCH (such as the system information block (SIB)) and / or paging messages.

[0092] like Figure 4CAs illustrated, some of the REs carry DMRS for channel estimation at the base station (indicated as R for a specific configuration, but other DMRS configurations are possible). The UE may transmit DMRS for PUCCH and DMRS for PUSCH. The PUSCH DMRS may be transmitted, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be transmitted in different configurations depending on whether a short PUCCH or a long PUCCH is transmitted and on the specific PUCCH format used. The UE 120 may transmit a sounding reference signal (SRS). The SRS may be transmitted, for example, in the last symbol of a subframe. The SRS may have a comb structure, and the UE may transmit the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0093] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at the position indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0094] Figure 5 is a diagram illustrating example 500 of sidelink communications.

[0095] like Figure 5As shown, a first UE 505-1 can communicate with a second UE 505-2 (and one or more other UEs 505) via a sidelink using one or more sidelink channels 510. UE 505-1 and UE 505-2 can communicate using one or more sidelink channels 510 for peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) communication (e.g., which may include vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, and / or vehicle-to-pedestrian (V2P) communication), and / or mesh networking. In some aspects, UE 505 (e.g., UE 505-1 and / or UE 505-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120 (which may be a baseline UE or a UE with threshold capabilities). In some aspects, one or more sidelink channels 510 can use a PC5 interface and / or can operate in a high frequency band (e.g., a 5.9 GHz band). Additionally or alternatively, the UE 505 may use Global Navigation Satellite System (GNSS) timing to synchronize the timing of transmit time intervals (TTIs) (eg, frames, subframes, time slots, or symbols).

[0096] like Figure 5 As further shown, one or more sidelink channels 510 may include a physical sidelink control channel (PSCCH) 515, a physical sidelink shared channel (PSSCH) 520, and / or a physical sidelink feedback channel (PSFCH) 525. Similar to the physical downlink control channel (PDCCH) and / or physical uplink control channel (PUCCH) used for cellular communication with BS 110 via an access link or access channel, PSCCH 515 may be used to convey control information. Similar to the physical downlink shared channel (PDSCH) and / or physical uplink shared channel (PUSCH) used for cellular communication with BS 110 via an access link or access channel, PSSCH 520 may be used to convey data. For example, PSCCH 515 may carry sidelink control information (SCI) 530, 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 transport blocks (TBs) 535 may be carried on PSSCH 520. The TB 535 may include data. The PSFCH 525 may be used to communicate sidelink feedback 540, 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).

[0097] Although shown on the PSCCH 515, in some aspects the SCI 530 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 transmitted on the PSCCH 515. The SCI-2 may be transmitted on the PSSCH 520. 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 520, 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 a modulation and coding scheme (MCS). SCI-2 may include information associated with data transmission on the PSSCH 520, 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.

[0098] In some aspects, one or more sidelink channels 510 may use a sidelink resource pool. A sidelink resource pool may include a configured set of time resources and frequency resources in which a sidelink UE 505 performs sidelink communications. A UE may be configured with one or more sidelink resource pools. A sidelink resource pool may be defined by a plurality of contiguous subchannels, each of which may be composed of a plurality of contiguous resource blocks or resource elements. The configuration of the sidelink resource pool may indicate transmission parameters for the UE 505 to communicate in the sidelink resource pool, as described in more detail elsewhere herein. A scheduling assignment (e.g., included in SCI 530) may be transmitted in a subchannel using specific resource blocks (RBs) across time. In some aspects, data transmissions associated with a scheduling assignment (e.g., on PSSCH 520) may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, the scheduling assignment and the associated data transmission are not transmitted on adjacent RBs.

[0099] In some aspects, the UE 505 may operate using a sidelink transmission mode (e.g., Mode 1) in which resource selection and / or scheduling is performed by the BS 110 (e.g., a gNB, CU, or DU). For example, the UE 505 may receive a grant for sidelink channel access and / or scheduling from the BS 110 (e.g., directly or via one or more network nodes) (e.g., in downlink control information (DCI) or in a radio resource control (RRC) message, such as for a configured grant). In some aspects, the UE 505 may operate using a transmission mode (e.g., Mode 2) in which resource selection and / or scheduling is performed by the UE 505 (e.g., rather than the BS 110). In some aspects, the UE 505 may perform resource selection and / or scheduling by sensing channel availability for transmission. For example, the UE 505 may measure received signal strength indicator (RSSI) parameters associated with various sidelink channels (e.g., sidelink RSSI (S-RSSI) parameters), may measure reference signal received power (RSRP) parameters associated with various sidelink channels (e.g., PSSCH-RSRP parameters), and / or may measure reference signal received quality (RSRQ) parameters associated with various sidelink channels (e.g., PSSCH-RSRQ parameters), and may select a channel for transmission of sidelink communications based at least in part on the measurements.

[0100] Additionally or alternatively, the UE 505 may perform resource selection and / or scheduling using the SCI 530 received in the PSCCH 515, which may indicate occupied resources and / or channel parameters. Additionally or alternatively, the UE 505 may perform resource selection and / or scheduling by determining a channel busy ratio (CBR) associated with various sidelink channels, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE 505 may use for a particular set of subframes).

[0101] In a transmission mode in which resource selection and / or scheduling is performed by the UE 505, the UE 505 may generate a sidelink grant and may transmit the grant in the SCI 530. The sidelink grant may indicate, for example, one or more parameters to be used for an upcoming sidelink transmission, such as one or more resource blocks to be used for the upcoming sidelink transmission on the PSSCH 520 (e.g., for TB 535), one or more subframes to be used for the upcoming sidelink transmission, and / or a modulation and coding scheme (MCS) to be used for the upcoming sidelink transmission. In some aspects, the UE 505 may generate a sidelink grant that indicates one or more parameters for semi-persistent scheduling (SPS), such as the periodicity of the sidelink transmission. Additionally or alternatively, the UE 505 may generate a sidelink grant for event-driven scheduling, such as for on-demand sidelink messages.

[0102] In some aspects, the UE 505 may be a baseline UE (e.g., a smartphone, an advanced smartphone, or an eMBB device, etc.). In some other aspects, the UE 505 may be a UE with threshold capabilities (e.g., capabilities below a threshold). UEs with threshold capabilities may include, for example, reduced capability (RedCap) UEs, ultralight UEs, or ultralight UEs, etc. UEs with threshold capabilities may experience relaxed peak throughput, latency, and / or reliability requirements. Threshold capabilities may include, for example, communication bandwidth capabilities, transmit power capabilities, power storage capabilities, sensing capabilities, or a combination thereof, etc. Examples of UEs with threshold capabilities include metering devices, asset tracking devices, and personal IoT devices. Implementing UEs with threshold capabilities in the sidelink may enable low power wide area (LPWA) use cases, such as improvements in coverage, complexity, and power consumption, as well as the utilization of low power and / or low complexity sidelink devices. Implementing a UE with threshold capabilities may also enable power-efficient sidelink operation, such as in relay use cases (where power savings are achieved by avoiding large numbers of repetitions for coverage extension) and wearable or home networking use cases (because short-range sidelink communications can use less power than long-range downlink or uplink communications).

[0103] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0104] Figure 6 is a diagram illustrating an example 600 of sidelink and access link communications.

[0105] like Figure 6 As shown, the transmitter (Tx) / receiver (Rx) UE 605 and the Rx / Tx UE 610 can communicate with each other via a side link, as described above in conjunction with Figure 5As further shown, in some sidelink modes, the network node 110 may communicate with the Tx / Rx UE 605, such as via a first access link (e.g., directly or via one or more network nodes). Additionally or alternatively, in some sidelink modes, the network node 110 may communicate with the Rx / Tx UE 610, such as via a first access link (e.g., directly or via one or more network nodes). The Tx / Rx UE 605 and / or the Rx / Tx UE 610 may correspond to one or more UEs described elsewhere herein, such as Figure 1 UE 120 of the present invention. Therefore, the direct link between UEs 120 (e.g., via the PC5 interface) may be referred to as a side link, and the direct link between network 110 and UE 120 (e.g., via the Uu interface) may be referred to as an access link. Sidelink communications may be sent via the side link, and access link communications may be sent via the access link. Access link communications may be downlink communications (from network node 110 to UE 120) or uplink communications (from UE 120 to network node 110).

[0106] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0107] Figure 7 is a diagram illustrating example 700 of candidate resource identification based at least in part on sensing. Example 700 relates to a mode in which a UE (e.g., UE 120, UE 505, UE 605, UE 610, a UE with threshold capability, a baseline UE) of a sidelink network autonomously determines resource allocation. Example 700 includes a sensing window and a resource selection window. Within the sensing window, the UE may decode an SCI, such as to determine whether resources in the resource selection window are available. The SCI may indicate resource reservations and may indicate a priority level associated with the resource reservations. In example 700, the resources reserved by each SCI are indicated by matching padding and an arrow from the SCI to the reserved resources.

[0108] The UE may perform sensing with respect to the SCI in the sensing window. For example, the UE may determine measurements with respect to the SCI, such as reference signal received power (RSRP) measurements. The UE may select resources in the resource selection window based at least in part on the measurements. Thus, measurements transmitted in association with the SCI may be projected onto the resource selection window. The UE may measure RSRP on the PSCCH or PSSCH (e.g., DMRS of the PSSCH), etc., according to a configuration (e.g., RRC configuration or pre-configuration, etc.). The sensing window may have a length that may be configured (e.g., RRC configuration or pre-configuration, etc.). The configurations for determining the resource selection window and the sensing window may be collectively referred to as parameter sets and are described in more detail elsewhere herein.

[0109] The UE may select resources based at least in part on measurements and / or priorities, which may be referred to as resource exclusion (where excluded resources are not selected). For example, the UE may determine whether resources in the resource selection window are associated with an SCI in the sensing window where the RSRP meets a threshold (e.g., a threshold for single-slot transmission, as described above). If the RSRP meets the threshold (e.g., if the RSRP is strong enough), the UE may determine that the reserved resources are not available. If the RSRP fails to meet the threshold, the resource is considered available. In some aspects, the UE may determine resource availability based at least in part on priority level. For example, the UE may ignore reservations associated with a lower priority level than the communication to be performed by the UE, or the UE may modify one or more thresholds associated with resource selection based at least in part on priority level. In some aspects, the resource selection window may be selected based on transmitter priority (e.g., priority level). TX ) and receiver priorities (e.g., prio RX ) pair, meaning the threshold is specific to the priority level associated with the transmitter of the communication and the receiver of the communication. In some aspects, the UE may adjust the threshold for RSRP. For example, if the proportion of available resources in the resource selection window is less than a threshold (e.g., 20%), the RSRP threshold may be increased and the process may be repeated.

[0110] The available resources in the resource selection window may form a candidate resource set. The UE may report the candidate resource set to higher layers of the UE (e.g., above the PHY layer). Resources may be selected for a transmission (e.g., a packet) such that all retransmissions for the transmission occur within a delay budget associated with the packet (e.g., a packet delay budget).

[0111] A UE (e.g., a layer of the UE) may receive or determine a resource selection trigger. The resource selection trigger indicates that the UE is to perform a transmission and, therefore, to select a resource. Upon receiving the resource selection trigger, the UE may time-step back to a sensing window based at least in part on a configured or pre-configured time window. The UE may select future resources within the resource selection window based at least in part on the sensing window.

[0112] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0113] Figure 8 Example operations 800 are illustrated for resource allocation using resource allocation mode 2. Higher layers may request, via a resource selection trigger, a UE (e.g., UE 120, UE 505, UE 605, UE 610, a UE with threshold capability, a baseline UE) to determine a subset of resources from which the higher layers may select resources for PSSCH / PSCCH transmission.

[0114] To trigger resource selection at time slot n, higher layers may provide multiple parameters including the t2min_SelectionWindow parameter. 2,min Can be set to the value for prio from the higher layer parameter t2min_SelectionWindow TX The corresponding value of a given value indicating the priority of the configuration {1,8,10,20} · 2 μ , where μ can be equal to {0, 1, 2, 3} for subcarrier spacing (SCS) {15, 30, 60, 120} kHz, respectively.

[0115] If T 2,min is shorter than the remaining packet delay budget (PDB) (in time slots), then T2 can be determined by the UE, and T 2,min T2 may be less than or equal to T2, which may be less than or equal to the remaining packet delay budget. 2,min It can be referred to as the second time length that defines the minimum length of the resource selection window. 2,min If the resource selection window size T2 is not shorter than the remaining packet delay budget, the resource selection window size T2 may be set to the remaining packet delay budget. The higher layer may also indicate a parameter T0 that indicates the sensing window size (e.g., the number of time slots). T0 may be referred to as the first time length defining the sensing window. The sensing window may be defined by a time slot range nT proc,0 (e.g., the start of time slot n minus the duration T proc,0, as shown). The UE may monitor time slots of the sidelink resource pool that may belong to the sensing window, but exclude those time slots in which the UE's own transmission occurs. The UE may decode SCI received from other UEs during the sensing window. The UE may determine the resources reserved via the SCI. For example, a sensing UE may receive SCI transmitted by another UE during sensing window 802. The SCI during the sensing window may reserve resources 804 for transmission.

[0116] Each UE may attempt to reserve resources in the future that may conflict with the resource selection window of the interested UE. For example, a sensing UE (e.g., an interested UE) may attempt to reserve resources during resource 804. Based on the priority (p) of the packet for which another UE is reserving resources (e.g., resource 804), the UE may reserve resources for the resource selection window of the interested UE. j ), the priority of the group of interested UEs (p i ), used for (p i ,p j ) and the RSRP measured by the UE of interest (based on reception of PSCCH / PSSCH (e.g., including SCI) from another UE), the UE of interest can determine whether a candidate resource (e.g., resource 804) is considered available (i.e., considered a candidate resource for selection). Therefore, the UE of interest can determine whether the use of resource 804 may cause interference to another UE. If the proportion of available resources in the resource selection window is less than a threshold (e.g., 20%), the threshold can be increased according to the step size, and the process is repeated. The available resources in the selection window form a set of candidate resources. The set of candidate resources is reported to higher layers. Resources can be selected so that all retransmissions for a packet must occur within the PDB of the packet.

[0117] Figure 9 An example technique 900 for resource reservation is illustrated. A sidelink resource pool 902 for baseline UEs (e.g., non-reduced capability UEs, UEs with greater than a threshold capability) may overlap (e.g., encompass) a portion 904 of the sidelink resource pool 902 for UEs with a threshold capability (e.g., the largest UE with a threshold capability). As described herein, UEs with a threshold capability may operate on a narrower bandwidth (e.g., portion 904), thereby allowing such UEs to operate with lower power consumption than baseline UEs.

[0118] In some aspects, a UE with a threshold capability may operate in a portion of the bandwidth of resource pool 902. When a baseline UE reserves a set of resources 908 in portion 904 via signaling 906 on resources that are not part of portion 904, the UE with the threshold capability may not be able to sense the signaling 906 in order to consider resources 908 when performing the reservation. As a result, a collision may occur (which may be power-consuming for the UE with reduced capability because it may result in retransmissions). The reservation made by the UE with the threshold capability may be detected by the baseline UE because the baseline UE is able to sense the entire resource pool 902, including portion 904.

[0119] The side link resource pool can be used to send PSSCH or receive PSSCH and can be associated with side link resource allocation mode 1 or side link resource allocation mode 2. For resource allocation mode 1, the side link (SL) resources used for transmission can be configured or dynamically indicated by the network entity via DCI format 3_0. Both type 1 (configuration-based only) SL resource configuration and type 2 (activation-based) SL resource configuration are supported. Resource allocation mode 2 is an autonomous mode in which the UE selects resources for its SL transmission based on sensing and reservation. In the frequency domain, the side link resource pool includes numSubchannel consecutive subchannels. A subchannel includes subchannelsize consecutive PRBs, where numSubchannel and subchannelsize are higher layer parameters.

[0120] As indicated above, Figure 9 are provided as examples. Other examples can be found in the Figure 9 The examples described are different.

[0121] Figure 10 is a diagram illustrating an example 1000 of signaling regarding a portion of a sidelink resource pool. Example 1000 includes a network entity (e.g., BS 110, Figure 3 One or more entities of a decomposed base station are described, including a programmable logic controller, a sidelink controller (UE), and a UE (e.g., UE 120, UE 505, UE 605, UE 610, a baseline UE, a UE with threshold capability).

[0122] like Figure 10 In the embodiment and indicated by reference numeral 1010, the network entity may configure a side link resource pool (e.g., side link resource pool 902). For example, the network entity may send a resource pool configuration indicating parameters defining the side link resource pool (e.g., Figure 9 One or more parameters in the description).

[0123] As indicated by reference numeral 1020, a network entity may transmit, and a UE may receive, a configuration for a portion of a sidelink resource pool (e.g., portion 904, a subband). In some aspects, the network entity may transmit the configuration indicated by reference numeral 1020 as part of the configuration of the sidelink resource pool. In some other aspects, the network entity may transmit the configuration separately from (e.g., after) the configuration of the sidelink resource pool. In some aspects, the network entity may configure multiple portions of the sidelink resource pool. Each portion may be configured via a corresponding configuration. At least one transmit parameter may differ between the portions. For example, a first configuration for a first portion of the sidelink resource pool may indicate at least one first transmit parameter specific to the first portion of the sidelink resource pool, and a second configuration for a second portion of the sidelink resource pool may indicate at least one second transmit parameter specific to the second portion of the sidelink resource pool. The at least one second transmit parameter may differ from the at least one first transmit parameter. The portions of a given sidelink resource pool may overlap or may not overlap. In some aspects, a baseline UE may communicate using the configuration of a portion of the sidelink resource pool. For example, the configuration may indicate reduced transmit power in a portion of the sidelink resource pool because a portion of the sidelink resource pool is shared with UEs having a threshold capability. The baseline UE may determine that the portion is shared with UEs having a threshold capability based on dynamic indications, configuration, or sensing in the portion, as described elsewhere herein.

[0124] In some aspects, the configuration may include one or more parameters indicating the difference ("delta") between the side link resource pool configuration and the configuration of a portion of the side link resource pool. For example, the configuration may indicate one or more first parameters of the first portion of the side link resource pool and one or more second parameters of the second portion of the side link resource pool. If the UE uses multiple portions of the side link resource pool, such as due to cross-time frequency hopping, the UE may use a parameter set for a portion of the side link resource pool currently used by the UE. If a parameter set for a portion of the side link resource pool currently used by the UE is not configured, the UE may use the side link resource pool configuration. Therefore, a UE (e.g., a UE with threshold capabilities) may be configured with multiple configurations (corresponding parameter sets and / or side link resource pool configurations indicating multiple portions of the side link resource pool), and may use an appropriate configuration from the multiple configurations based on which portion of the side link resource pool the UE uses for communication. In some aspects, two or more configurations (corresponding to two or more different side link resource pools) in the multiple configurations may be identical to each other.

[0125] In some aspects, a portion of the sidelink resource pool may have different configurations for a UE with a threshold capability and a baseline UE. For example, when communicating in a portion of the sidelink resource pool, a UE with a threshold capability may use a first configuration and a baseline UE may use a second configuration that is different from the first configuration. In some aspects, the first configuration and / or the second configuration may include an indication of

[0126] As shown, the configuration may indicate at least one transmit parameter that is specific to a portion of the sidelink resource pool. The at least one transmit parameter may be specific to a portion of the sidelink resource pool because the at least one transmit parameter is used for operations (e.g., transmission, measurement, channel sensing, resource selection) within the portion of the sidelink resource pool and is not used for operations in the sidelink resource pool or operations outside of the portion of the sidelink resource pool. For example, a power control parameter that is specific to a portion of the sidelink resource pool may be used for transmissions within the portion of the sidelink resource pool and is not used for transmissions outside of the portion of the sidelink resource pool.

[0127] In some aspects, the transmission parameters may include power control parameters. The power control parameters are parameters used to determine the transmit power of the UE. For example, the UE may use the formula To determine the transmit power P of PSSSCH PSSCH,SL (i). In this formula, P O,SL is the power target value (which may indicate the power required at the receiving device and which may be referred to as the received power per resource block), α SL is the fractional power control parameter, PL SL is the side link path loss, Delta subRPindex is the power control offset value, is the PSSCH bandwidth expressed in resource blocks, and PCMAX is the maximum UE output power value. In the above formula, the power target value, the fractional power control value, the power control offset value, and the maximum UE output power value can be considered as transmission parameters and can be configured for a portion of the sidelink resource pool. In some aspects, the configuration of a portion of the sidelink resource pool may indicate whether the path loss of the above formula is derived from a sidelink measurement (e.g., a measurement of a sidelink reference signal) or from a downlink measurement (e.g., a measurement of a downlink reference signal). In some aspects, the path loss may be specific to a portion of the sidelink resource pool. For example, the path loss may be derived from measurements performed in a portion of the sidelink resource pool.

[0128] The power control offset value may indicate an offset (e.g., in dBm or dB) to be applied to the transmit power when the UE is transmitting in a portion of the sidelink resource pool. For example, the power control offset value may cause the UE to reduce the transmit power of the UE when transmitting in a portion of the sidelink resource pool, thereby reducing interference to UEs with threshold capabilities in the sidelink resource pool. The power control offset value (and / or one or more other transmit parameters described herein) may be configured or indicated via Layer 3 (e.g., RRC) signaling, Layer 2 (e.g., MAC) signaling, or Layer 1 (e.g., dynamic, DCI) signaling. For example, Layer 1 signaling may indicate a power control offset value selected from a plurality of power control offset values ​​configured (via Layer 3 or Layer 2 signaling). In some aspects, the power control offset value may be based at least in part on whether UEs with threshold capabilities are available or present in a portion of the sidelink resource pool. For example, if a portion of the sidelink resource pool is configured for a UE with a threshold capability, the configuration of the sidelink resource pool may include a power control offset parameter, and if a portion of the sidelink resource pool is not configured for a UE with a threshold capability, the configuration of the sidelink resource pool may not include a power control offset parameter. Thus, the UE may perform closed-loop power control on the portion of the sidelink resource pool. The UE may apply one or more power control parameters as described below in connection with the transmission of sidelink communications in the portion of the sidelink resource pool at reference numeral 1040.

[0129] In some aspects, the at least one transmission parameter may include a channel sensing parameter. For example, the at least one transmission parameter may indicate a first time length defining a sensing window (e.g., in conjunction with Figure 8 T0 as described above) (e.g., selected from a configured or preconfigured value such as 100ms or 1100ms), a second time length defining a minimum length of the resource selection window (e.g., in combination with Figure 8 Description of T 2,min ) (e.g., which may be configured or pre-configured as {1,5,10,20}·2μ, μ=0,1,2,3, for SCS15kHz, 30kHz, 60kHz and 120kHz, respectively) by priority and by subcarrier spacing, or a combination thereof. In some aspects, the sensing window and / or resource selection window may be longer in a portion of the sidelink resource pool associated with the threshold-capable UE than in a portion of the sidelink resource pool not associated with the threshold-capable UE. For example, providing a longer sensing window and / or resource selection window for the baseline UE may reduce interference to the threshold-capable UE in a portion of the sidelink resource pool associated with the threshold-capable UE.

[0130] In some aspects, at least one transmitted parameter (e.g., a channel sensing parameter) may indicate an increment for a threshold used for candidate resource identification. For example, a UE may use the threshold for candidate resource identification to perform resource selection. If the proportion of available resources in the selection window (which may be an RSRP threshold, an RSRQ threshold, or a signal-to-interference-plus-noise (SINR) threshold, depending on the threshold used for candidate resource identification) falls below a threshold (e.g., 20%), the UE may increase the threshold for candidate resource identification by an increment and repeat the candidate resource identification. The available resources in the resource selection window may form a set of candidate resources, which may be reported to higher layers as described above. In some aspects, the increment for the threshold may be specific to a portion of the sidelink resource pool. For example, the configuration may indicate the increment. Thus, the threshold for candidate resource identification may be derived using at least one transmitted parameter (because the increment for the threshold for candidate resource identification may be consistent with the at least one transmitted parameter). Implementing different increments based on whether a portion of the sidelink resource pool is associated with a threshold-capable UE may reduce interference to threshold-capable UEs because the UE is more likely to avoid selecting occupied resources with smaller increments than with larger increments.

[0131] In some aspects, at least one transmit parameter may include a modulation and coding scheme (MCS) parameter. For example, the MCS parameter may indicate a restricted MCS value (e.g., a maximum MCS, a minimum MCS, a set of allowed MCSs, or a specific MCS) for transmission in a portion of the sidelink resource pool. As another example, the MCS parameter may indicate a restricted MCS table (e.g., a specific MCS table, or one or more allowed rows or entries of one or more MCS tables) that may be used for transmission in a portion of the sidelink resource pool. In some aspects, at least one transmit parameter may include an antenna port parameter. For example, the antenna port parameter may indicate a restricted rank value (e.g., a maximum rank, a minimum rank, a set of allowed ranks, or a specific rank) for transmission in a portion of the sidelink resource pool. As another example, the antenna port parameter may indicate a restricted antenna port value (e.g., a maximum number of antenna ports, a minimum number of antenna ports, a set of allowed antenna ports or numbers of antenna ports, or a specific number of antenna ports) for transmission in a portion of the sidelink resource pool. In some aspects, at least one transmit parameter may indicate a beam parameter. For example, at least one transmission parameter may indicate one or more beams (e.g., analog beams, digital beams, beam widths, beam directions, or combinations thereof) that are allowed in a portion of the sidelink resource pool, one or more beams that are not allowed in a portion of the sidelink resource pool, or a combination thereof. In some aspects, the beam parameters may be based at least in part on positioning information. For example, the beam parameters may indicate a particular beam that is not allowed based at least in part on the location of the UE (e.g., so that the UE's beam does not interfere with UEs with a threshold capability located in the coverage area of ​​the beam).

[0132] In some aspects, a configuration may indicate whether a portion of a sidelink resource pool is associated with a UE having a threshold capability. For example, a configuration may indicate whether one or more UEs having a threshold capability are configured to communicate in a portion of a sidelink resource pool. In some aspects, one or more transmission parameters of the configuration may apply to a portion of the sidelink resource pool associated with a UE having a threshold capability, and may not apply if the portion is not associated with a UE having a threshold capability.

[0133] The configuration shown by reference numeral 1020 may be signaled via layer 1 signaling, layer 2 signaling, layer 3 signaling, or a combination thereof. In some aspects, the network entity may output, and the UE may receive, signaling to update the configuration shown by reference numeral 1020 (e.g., one or more transmission parameters). The signaling to update the configuration may include layer 1 signaling, layer 2 signaling, layer 3 signaling, or a combination thereof.

[0134] As shown at reference numeral 1030, the UE may communicate based at least in part on at least one transmit parameter. For example, the UE may transmit communications in a portion of a sidelink resource pool using the at least one transmit parameter, as shown at reference numeral 1040. As another example, the UE may perform sensing and / or resource selection in a portion of a sidelink resource pool based at least in part on the at least one transmit parameter, as shown at reference numeral 1050. In some aspects, the UE may communicate based at least in part on the at least one transmit parameter based at least in part on an indication to use the at least one transmit parameter. For example, the network entity may provide an indication to begin using the at least one transmit parameter (e.g., via layer 1 signaling, layer 2 signaling, and / or layer 3 signaling). As another example, the network entity may provide an indication to cease using the at least one transmit parameter (e.g., via layer 1 signaling, layer 2 signaling, and / or layer 3 signaling).

[0135] As indicated by reference numeral 1040, the UE may transmit communications in a portion of the sidelink resource pool using at least one transmit parameter. For example, the UE may transmit communications using an MCS parameter, a beam parameter, an antenna port parameter, at least one power control parameter, or a combination thereof. In some aspects, if the UE is a baseline UE and the communication is in a portion of the sidelink resource pool, the UE may transmit communications using at least one transmit parameter. In some aspects, if a UE with a threshold capability is associated with a portion of the sidelink resource pool (e.g., if a portion of the sidelink resource pool is configured for a UE with a threshold capability, or if a UE with a threshold capability is transmitting or receiving in a portion of the sidelink resource pool), the UE may transmit communications using at least one transmit parameter. For example, the network entity may provide an indication that a portion of the sidelink resource pool is configured for or used by a UE with a threshold capability, and may also provide an indication of resources in the portion of the sidelink resource pool used by a UE with a threshold capability. As another example, a UE with a threshold capability may transmit a reservation (e.g., an SCI) for resources used by a UE with a threshold capability. The reservation may identify a UE with a threshold capability (e.g., may include an identifier of the UE, or may indicate that the UE has the threshold capability). For such resources or portions of the sidelink resource pool, in some aspects, the UE may not transmit within the resources or portion. In some other aspects, the UE may transmit within the resources or portion using the at least one transmission parameter (e.g., a power control parameter or an MCS parameter, etc.).

[0136] In some aspects, the UE may not communicate within a portion of the sidelink resource pool. For example, the UE may transmit communications within the sidelink resource pool but outside of the portion of the sidelink resource pool. This may be based on the portion of the sidelink resource pool being associated with a UE having a threshold capability and / or based on the UE being a baseline UE.

[0137] As another example, the UE may perform sensing and / or resource selection in a portion of the sidelink resource pool based at least in part on at least one transmit parameter, as shown in reference numeral 1050. For example, the UE may perform sensing based on a threshold for candidate resource identification, as described above. The threshold may be associated with an increment indicated by at least one transmit parameter. The UE may identify resources that meet the threshold as a set of candidate resources. The UE may select resources for transmission from the set of candidate resources. For example, the UE may perform a random selection from the set of candidate resources (e.g., using a random seed or a pseudo-random sequence, etc.). Thus, the selection of resources for transmission (which may be random) may be based on at least one transmit parameter because the identification of candidate resources from which the resources are selected for transmission uses the threshold for candidate resource selection. As another example, the UE may exclude resources from the set of candidate resources that are indicated as being used by UEs with threshold capabilities (e.g., based on signaling from a network entity or a reservation from a UE with threshold capabilities).

[0138] In some aspects, a UE may transmit communications based at least in part on sensing and / or resource selection. For example, if a resource satisfies a threshold for candidate resource selection (e.g., an RSRP threshold, an RSRQ threshold, an SINR threshold) by less than a threshold amount (where the threshold amount may be indicated by configuration via layer 1 signaling, layer 2 signaling, or layer 3 signaling), the UE may apply at least one transmit parameter for transmitting on the resource. For example, the UE may apply a transmit power parameter and / or an MCS parameter for transmitting on the resource.

[0139] As indicated above, Figure 10 are provided as examples. Other examples can be found in the Figure 10 The examples described are different.

[0140] Figure 11 A method 1100 for wireless communications by a UE, such as UE 120, is shown.

[0141] Method 1100 begins, at 1110 , by receiving a configuration for a portion of a sidelink resource pool, the configuration indicating at least one transmission parameter specific to the portion of the sidelink resource pool.

[0142] Method 1100 then proceeds to step 1120 of communicating based at least in part on at least one transmission parameter.

[0151] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, the configuration indicates that the portion of the sidelink resource pool is associated with a UE having a threshold capability.

[0152] In a tenth aspect, alone or in combination with one or more of the first to ninth aspects, communicating based at least in part on at least one transmission parameter further comprises communicating outside the portion of the sidelink resource pool.

[0153] In an eleventh aspect, alone or in combination with one or more of the first to tenth aspects, method 1100 includes transmitting in the resource using one or more transmission parameters.

[0154] In a twelfth aspect, alone or in combination with one or more of the first to eleventh aspects, method 1100 comprises: transmitting on the resource using one or more transmission parameters.

[0155] In one aspect, method 1100 or any aspect related thereto may be performed by an apparatus such as Figure 13 The method 1100 is performed by a communication device 1300 comprising various components operable to, configured to, or adapted to perform the method 1100. The communication device 1300 is described in more detail below.

[0156] Please note that Figure 11 This is merely one example of a method, and other methods including fewer, additional, or alternative steps are possible in light of the present disclosure.

[0157] Figure 12 10 or 110. Figure 3 A method 1200 of performing wireless communications with a decomposed base station is discussed.

[0158] The method 1200 begins at 1210 by outputting a first configuration of a first portion of a sidelink resource pool, the first configuration indicating at least one first transmission parameter specific to the first portion of the sidelink resource pool.

[0159] The method 1200 then proceeds to step 1220 of outputting a second configuration of the second portion of the sidelink resource pool, the second configuration indicating at least one second transmission parameter specific to the second portion of the sidelink resource pool.

[0160] In a first aspect, the at least one transmission parameter includes at least one of the following: a power control parameter, a channel sensing parameter, a modulation and coding scheme parameter, an antenna port parameter, or a beam parameter.

[0161] In a second aspect, either alone or in combination with the first aspect, at least one transmission parameter comprises a power control parameter, and the power control parameter comprises at least one of the following: a maximum UE output power value, a path loss value, a fractional power control parameter, a power target value, or a power control offset value.

[0165] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the method 1200 includes outputting an indication of resources in a first portion of a sidelink resource pool reserved for a specific UE having a threshold capability.

[0166] In one aspect, method 1200 or any aspect related thereto may be performed by an apparatus such as Figure 14 The method 1200 is performed by a communication device 1400 comprising various components operable, configured or adapted to perform the method 1200. The communication device 1400 is described in more detail below.

[0167] Please note that Figure 12 This is merely one example of a method, and other methods including fewer, additional, or alternative steps are possible in light of the present disclosure.

[0168] Figure 13 is a diagram illustrating an example of a specific implementation of codes and circuits for a communication device 1300. The communication device 1300 may be a UE, or a UE may include the communication device 1300.

[0169] The communication device 1300 includes a processing system 1302 coupled to a transceiver 1308 (e.g., a transmitter and / or receiver). The transceiver 1308 is configured to transmit and receive signals for the communication device 1300, such as the various signals described herein, via an antenna 1310. The processing system 1302 may be configured to perform processing functions for the communication device 1300, including processing signals received by the communication device 1300 and / or to be transmitted by the communication device.
