  • Publication number: 20230057169
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability report to a base station indicating a triggering offset. The base station may configure the UE with one or more channel state information (CSI) measurement resources and send downlink control information (DCI) that triggers an aperiodic CSI report for some of the CSI measurement resources. The UE may report CSI by measuring the CSI resources after the triggering offset. In some cases, CSI reporting related to the different codebook types (e. g., Type I, Type II) may be modified, where after identifying a type of codebook and determining which type of codebook to process (e. g., based on a number of CSI processing units), the UE may identify a priority associated with different CSI reports. The UE may be configured with various parameters that relax or modify the processing of Type II CSI reports.

  • Publication number: 20230040058
    Abstract: Methods, systems, and devices for wireless communications are described to support communication between a base station and a user equipment (UE) via multiple transmission reception points (TRPs). The base station may configure the UE to report a precoding matrix indicator (PMI) for various transmission modes, including one or more transmission modes for multiple TRPs. The UE may determine and report first PMI to the base station for each single TRP transmission mode, and the base station may use the first PMI to determine a precoding matrix for each TRP. The UE may determine and report partial PMI to the base station for the one or more multi-TRP transmission modes. The base station may use respective partial PMI to determine a precoding matrix for each multi-TRP transmission mode and may communicate with the UE using the determined precoding matrix or matrices.

  • Patent number: 11570822
    Abstract: Methods, systems, and devices for wireless communications are described. In a random access (RACH) procedure, a user equipment (UE) may transmit a first RACH message (e.g., RACH Message A (MsgA)) to a base station, which may include an indication of a modulation order, a maximum number of repetitions for RACH Message B (MsgB) data, or both. The base station may multiplex random access responses (RARs) for UEs into second RACH messages (e.g., RACH MsgBs) based on the indication(s) and may transmit these RACH MsgBs. The UE may receive and decode a downlink control information (DCI) portion of a RACH MsgB but may determine not to decode the data portion of the RACH MsgB if an indication in the DCI of the modulation order, the threshold number of repetitions, or both does not match the value reported by the UE. Otherwise, the UE may decode the full RACH MsgB.

  • Publication number: 20230015843
    Abstract: Methods, systems, and devices are described for transmitting multiple repetitions of a random access shared channel message in multiple slots using beamformed wireless communications. A UE may determine transmission slots for one or more of the multiple repetitions of a random access shared channel message based on slots associated with random access occasions (ROs) that are mapped to an identified synchronization signal block (SSB), such as a SSB associated with a beam that is selected for communications by the UE. In cases where slots with ROs mapped to the identified SSB are not consecutively located, one or more slot offsets may be provided for transmitting the multiple repetitions of the random access shared channel message. Slot offsets may be explicitly indicated by a base station in a random access response message, or may be determined by the UE based on a mapping of SSBs to ROs.
