  • Publication number: 20230396378
    Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

  • Patent number: 11838089
    Abstract: Systems and methods for control signaling for beam searching latency reduction are disclosed herein. A g Node B (gNB) may determine that a first Synchronization Signal Block (SSB) and a second SSB are to be spatially correlated and may select a first transmit (Tx) beam to transmit the first SSB and a second Tx beam to transmit the second SSB accordingly. The gNB may also transmit a correlation message including spatial correlation information to help a UE determine the spatial correlation. The UE may measure the first SSB on a first subset of a plurality of receive (Rx) beams and measure the second SSB on a second subset of the plurality of Rx beams, and select an Rx beam for one or both. In some embodiments, channel state information reference signals (CSI-RS) that are quasi co-located (QCLed) with a given SSB may be measured in place of the SSB.

  • Patent number: 11825501
    Abstract: Various radio resource management techniques may be implemented to reduce in-device coexistence issues and/or interference between a Uu link established between a mobile device (first UE) and a base station (first NB), and a sidelink/PC5 link established between the first UE and another mobile device (second UE), where the second UE is served by a different base station (second NB). The first UE may receive, from the first NB, measurement configuration information that enables/configures the first UE to report to the NB any indication(s) of issues caused by communications between the first UE and the second UE over the PC5 link affecting communications between the first UE and the first NB over the Uu link, and/or communications over the Uu link affecting communications over the PC5 link. The first NB may analyze the feedback from the first UE and may implement mitigation measures to reduce/eliminate any interference and/or in-device-coexistence issues.

  • Publication number: 20230362896
    Abstract: Some embodiments include a system, method, and computer program product for managing power consumption of a user equipment (UE) supporting sidelink discontinuous reception (SL-DRX) in a 5G wireless communications system. A UE determines a candidate slot for sending a signal based on data sensed in various periods over a history window. Some embodiments include a processor that can determine set of candidate slots that are sufficiently sensed based on sensed periods over a history window, and determine a subset of candidate slots of the set of candidate slots based at least on an occupancy threshold over the history window. The processor can select a candidate slot from the subset of candidate slots, and transmit via the transceiver, a first signal via the selected candidate slot.

  • Patent number: 11812396
    Abstract: A transmitter (e.g. a packet data convergence protocol, PDCP, in the transmitter), which may be a base station for downlink communications or a user equipment device for uplink communications, may control timing of the delivery of duplicate (same) packets to multiple (e.g. two) wireless links (e.g. radio link control links) for transmission to a receiver, based at least on synchronization information received from the receiver. The duplicate packets may be transmitted over the multiple wireless links to the receiver, which may receive the duplicate packets over the multiple wireless links. The receiver may collect and/or generate synchronization information indicative of the timing or latency between the multiple wireless links, based at least on the respective receive timings of the duplicate packets over the multiple wireless links. The receiver may transmit a report containing the synchronization information to the transmitter periodically and/or in response to a trigger event.

  • Publication number: 20230354212
    Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.
