摘要： Certain aspects of the present disclosure relate to communication systems, and more particularly, to a partial channel state information reference signal (CSI-RS) port indication. A method by a base station (BS) includes configuring a user equipment (UE) with a CSI-RS resource, of one or more CSI-RS resources associated with a CSI report. The CSI-RS includes a set of CSI-RS ports. The BS provides a first indication to the UE of a subset of groups of the CSI-RS ports to be used by the UE for channel measurements and/or a second indication to the UE of a subset of groups of the CSI-RS to be used by the UE for interference measurements. Based on the indication, the UE performs channel measurements and/or interference measurements using the indicated subset of CSI-RS ports.

摘要： Aspects of the present disclosure relate to techniques for non-codebook based uplink (UL) transmission. In some cases, a user equipment (UE) may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.

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： 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： Certain aspects of the present disclosure relate to techniques for cross-carrier indication of TDD (Time Division Duplex) UL (Uplink)/DL (Downlink) subframe configuration. A UE may receive a configuration of a first index for a first cell, wherein the first index is mapped to a first position in a Downlink Control Information (DCI) message. The UE may receive the DCI message in a subframe and determine an indication of a UL/DL subframe configuration for the first cell based on the first index and the DCI message. The UE may communicate with the first cell based on the determined UL/DL subframe configuration for the first cell.

摘要： Aspects of the present disclosure relate to techniques that may help enable the determination of uplink resource allocation in systems that support dynamic uplink-downlink subframe configurations. An example method generally includes receiving signaling indicating a dynamic uplink-downlink (UL-DL) subframe configuration, determining hybrid automatic repeat request (HARQ) acknowledgment/negative acknowledgment (ACK/NACK) timing based on a reference UL-DL subframe configuration, and determining HARQ resource allocation based on the dynamic UL-DL subframe configuration.
