摘要： Certain aspects of the present disclosure provide techniques for layer mapping for multiple transmission reception point (TRP) transmission, for example, for code block group (CBG) based hybrid automatic repeat request (HARQ) acknowledgement feedback in new radio (NR). Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The UE receives one or more transport blocks (TBs) from a plurality of TRPs. Each of the one or more TBs comprises a plurality of CBs. For one or more of the plurality of CBs, all bits of the CB are received from a same TRP. The UE decodes the one or more TBs.

摘要： Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing occupation determination that can be used even in multiple transmission reception point (mTRP) scenarios. A method that may be performed by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs). The method includes determining a number of occupied CSI processing units, a number of occupied active CSI resources, and/or a number of occupied active CSI-RS ports based on an actual number of CSI measurements. The method includes performing CSI measurement based on the determination.

摘要： A base station may determine co-phase information and uplink precoding information (e.g., user equipment (UE) precoder information) based on one or more received sounding reference signals (SRSs) from a UE. The UE may adjust precoders or co-phase for different SRS transmissions over the one or more configured SRS resources. As such, the base station may indicate either co-phase information or uplink precoding information via an SRS resource indicator (SRI), and may transmit an explicit indication of the remaining co-phase information or uplink precoding information in addition to the SRI. In other examples (e.g., when only a single SRS resource is configured), the base station may transmit an index corresponding to uplink precoding information, as well as a separate indication of co-phase information. In some cases, a port selection pattern may be included with an explicit indication, indicating a selection of antenna port indices the precoder or co-phase index applies to.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform channel state information measurements on reference signal transmissions from a base station. The UE may identify a set of cross layer coefficients associated with a set of spatial layers based on the channel state information measurements. The UE may additionally identify a set of precoding coefficients associated with a spatial layer from the set of spatial layers. In some implementations, the set of precoding coefficients may be based on the set of cross layer coefficients. In some examples, the UE may transmit the set of cross layer coefficients and the set of precoding coefficients to the base station.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to use one or more channel state information (CSI) omission configurations for omitting portions of a CSI report. For example, a UE may receive a trigger to report CSI, and the UE may identify that a payload of the CSI report exceeds a capacity of resources for transmitting the report. As such, the UE may determine to use one or more CSI omission configurations, where each CSI omission configuration may correspond to dropping different portions of the CSI report. The selection of the CSI omission configuration to use may be based on a set of parameters associated with CSI reporting. In some cases, the UE selects the CSI omission configuration based on an explicit indication from the base station. Additionally or alternatively, the UE may implicitly determine the CSI omission configuration based on the parameters.

摘要： Certain aspects of the present disclosure provide techniques for reducing overhead for channel state information (CSI). Certain aspects provide a method for wireless communication. The method generally includes receiving a channel state information reference signal (CSI-RS), determining one or more feedback components associated with a CSI feedback type based on the CSI-RS, identifying that a payload of the one or more feedback components is to be compressed, compressing the payload, and reporting the compressed payload.
