Various aspects of the present disclosure relate to an apparatus for physical sidelink feedback channel (PSFCH) resource configuration. The apparatus, such as a sidelink transmitting UE, receives a configuration indicating multiple PSFCH occasions per physical sidelink shared channel (PSSCH) transmission in a resource pool, where the multiple PSFCH occasions are each configurable in more than one resource block (RB) set. The apparatus transmits a sidelink communication to a receiving UE based at least in part on a determination to transmit in a PSFCH occasion according to the PSSCH transmission in a RB set.

Various aspects of the present disclosure relate to methods, apparatuses, and systems that support timing alignment acquisition. For instance, implementations provide an optimized RACH procedure performed for the purpose of early acquisition of timing alignment information, e.g., before a handover occurs. Further, implementations provide for ways for a UE engaging in early timing alignment acquisition to respond to a cell switch instruction.

Various aspects of the present disclosure relate to an apparatus, such as a transmitting user equipment (UE) (e.g., a target UE) that receives, from a base station, a sidelink (SL) positioning reference signal (PRS) configuration of multiple resource sets. The transmitting UE also receives, from an anchor UE, a SL-PRS resource in at least one of a UE-specific resource element offset or a frequency offset. The transmitting UE transmits, to the anchor UE, a determined candidate SL-PRS resource for PRS transmission within a resource set of the multiple resource sets.

Various aspects of the present disclosure relate to methods, apparatuses, and systems that support multiple nodes for user equipment positioning. For instance, anchor nodes are configured to cooperate (e.g., via backhaul and/or OTA transmission) to exchange position-related parameters and confidence information pertaining to the position-related parameters. Further, subband non-overlapping full duplex (SBFD) can be used for OTA transmission to occur in a DL subband that is configured to overlap with the UL subband.

Various aspects of the present disclosure relate to providing efficient support of multiple traffic flows (e.g., data traffic flows) for various applications, such as extended reality applications. Different ones of these multiple traffic flows can have different characteristics, such as different quality of service characteristics. A network entity, such as a base station, transmits semi-persistent scheduling (SPS) configurations to one or more other devices in the wireless communications system, such as a user equipment. An SPS configuration includes one or more discontinuous reception (DRX) timer configurations that the network entity can set according to any of the characteristics of one or more of the traffic flows. The network entity selects one or more timers, and appropriate values for those timers based on the characteristics of one or more of the traffic flows, configuring the SPS to support the requirements of the one or more traffic flows.

Various aspects of the present disclosure relate to methods, apparatuses, and systems that support user equipment (UE) association with a network. For instance, implementations provide ways for UE registration requests and UE policy provisioning to be processed by a network. In implementations, payload containers of a registration request are processed separately by an access and mobility management function (AMF) and are transmitted to a policy control function (PCF) using two different hypertext transfer protocol (HTTP) POST request messages. The PCF implements a timer to ensure that both the HTTP POST messages are received by the PCF before the PCF initiates creating UE policy sections. In additional or alternative implementations, an AMF processes payload containers of a registration request into one payload. A PCF can then process new information identities and, in at least some implementations, identify and separate payload containers.

There is provided an apparatus comprising: a processor arranged to execute an application; and a receiver arranged to communicate with a wireless communications network, the receiver arranged to receive traffic category information from a network node in the wireless communications network, the network node remote from the apparatus; wherein the processor is further arranged to associate a traffic category to the application using the traffic category information.

A transceiver can receive a configuration of multiple beams, a respective duration of validity of each of the beams for an apparatus, and an indication of location related information, where the beams provide communication between the apparatus and a network entity. A controller can determine a set of the multiple beams to apply for communications based on at least the location related information and the duration of validity of each beam. The transceiver can communicate on different beams of the set of the beams at different time instances based on at least the location related information and the duration of validity of each beam.

A method and apparatus are provided for assigning a user equipment transmitter local oscillator frequency including informing the network of a capability of the user equipment to adjust a frequency location of a transmit local oscillator of the user equipment, to a frequency location which has been identified by the network, within a predefined channel frequency spectrum. The frequency location identification to be used to adjust the frequency location of the transmit local oscillator is received from the network. The frequency location of the local oscillator is then adjusted in accordance with the frequency location identification received.

An apparatus and method are provided where an interlaced based resource block configuration is received ( 702 ), which includes a physical resource block mapping for one or more bandwidth parts. Each bandwidth part includes a plurality of resource block sets each having a first defined size for mapping a plurality of subchannels of a second defined size into the respective resource block set, where the second defined size does not divide evenly into the first defined size. One or more remaining physical resource blocks that number less than the second defined size remain unassigned after a maximum number of subchannels are created. The remaining physical resource blocks are associated with one or more common interlaces for use as resource blocks for use as part of one or more physical sidelink feedback channels ( 704 ).
