  • Patent number: 11956670
    Abstract: A user equipment (UE) is configured to communicate with a further UE via a sidelink (SL). The UE encodes traffic for transmission to the further UE, wherein the traffic comprises a payload and a medium access control (MAC) subheader, wherein the MAC subheader indicates whether the payload corresponds to non-routed traffic between the UE and the further UE or routed traffic between either one of the UE or the further UE and a base station, wherein an other one of the UE or the further UE functions as a relay for the routed traffic and transmits the traffic.

  • Publication number: 20240114484
    Abstract: Systems and methods for sidelink (SL) power control within wireless communication systems are disclosed herein. A user equipment (UE) selects a parameter set to use to calculate a transmit power of one or more channels to be transmitted according to an SL session with a peer UE from a plurality of parameter sets each configured for use according to a distance between the UE and the peer UE. A UE determines whether an SL pathloss based calculation is to be used to calculate a transmit power of a channel according to an SL session with a peer UE, wherein that calculation is configured to be used depending on a distance between the UE and the peer UE. UE selection of a number of physical SL feedback channel (PSFCH) transmissions to match a UE capability and determinations regarding whether to perform PSFCH reception or PSFCH transmission are also discussed.

  • Patent number: 11950263
    Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

  • Patent number: 11950208
    Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method indicates a frequency resource reservation in sidelink control information (SCI). The method includes identifying a transport block (TB) for transmission to a UE; determining a total number of sub-channels (NSL) in a resource pool for sidelink communication, a number of sub-channels (Lsub) of the TB, a first starting sub-channel index x1 of a first retransmission of the TB, and a second starting sub-channel index x2 of a second retransmission of the TB. The method includes determining a frequency resource indication value (FRIV) based on NSL, LSUB, x1, and x2, wherein the FRIV represents a result of a predetermined function of Lsub, x1, and x2 that generates a unique value for possible combinations of Lsub, x1, and x2. The FRIV is encoded in SCI and the SCI is transmitted to the UE.
