  • Publication number: 20230328802
    Abstract: A wireless user equipment (UE) device may transmit a random access preamble to a base station, using a physical resource on an uplink signal. After failing to receive an initial transmission of a response message from the base station (BS), the UE device may monitor for one or more retransmissions of the response message. Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.

  • Patent number: 11777673
    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: 11777691
    Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.
