  • Publication number: 20240097746
    Abstract: Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value.

  • Patent number: 11909532
    Abstract: Techniques discussed herein can facilitate successful decoding of Physical Downlink Shared Channel (PDSCH) based on a reduced number of retransmissions. Based on a given PDSCH, embodiments discussed herein can communicate feedback (e.g., Hybrid Automatic Repeat reQuest (HARQ) feedback, Channel State Information (CSI) feedback) that indicates an amount of additional information that can allow a User Equipment (UE) to successfully decode the PDSCH. In some embodiments, the feedback can indicate a requested Redundancy Version (RV) sequence that can allow the UE to successfully decode the PDSCH. In other embodiments, the feedback can indicate the amount of additional information, based on which a receiving Base Station (BS) can select a RV sequence.

  • Publication number: 20230300641
    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing channel state information (CSI) reporting that includes a stale CSI report. Based at least in part on a CSI reporting configuration, a user equipment (UE) performs CSI measurements during a current reference time period, and generates one or more CSI reports including at least a stale CSI report. A stale CSI report is generated based at least in part on CSI measurements performed prior to the current reference time period. The UE further generates an uplink message including the one or more CSI reports, and transmits the uplink message to the base station under a reporting setting determined by the CSI reporting configuration.

  • Publication number: 20230246685
    Abstract: A user equipment (UE), or other network component can operate to configure channel state information (CSI) feedback in response to receiving a CSI-reference signal (CSI-RS) according to a hierarchical precoding scheme that selectively reduces a feedback overhead associated with the CSI feedback. The UE can operate to divide and further sub-divide a frequency band (e.g., a wideband, or particular frequency part) into a precoding hierarchy to generate precoders for conveyance to a base station, eNodeB (eNB), or next generation NodeB (gNB) via the CSI feedback.
