Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may perform beam measurements for one or more subsets of beams that are selected to provide enhanced beam switch determinations. The UE may identify one or more prioritized beams, and may measure the prioritized beams at a same periodicity as measurements of a serving beam. The UE may, additionally or alternatively, identify a set of all layer one beams (e.g., maximum-level beams or top level beams) for measurement according to a periodic interval, based on a measured mobility being less than a threshold value. The periodic interval may provide that each layer one beam may be measured at a cadence of one beam per measurement occasion, in order to provide measurement diversity.

Techniques for beam selection based on measurement periodicities

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a slot or a symbol where a channel state information reference signal (CSI-RS) for a Procedure 2 (P2) resource is to be scheduled. The UE may schedule a candidate UE beam or a serving UE beam for the slot or the symbol. The UE may measure a spectral efficiency associated with the P2 resource. The UE may prepare a report that indicates one or more characteristics of the candidate UE beam or the serving UE beam. Numerous other aspects are described.

User equipment beam management

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a sounding reference signal (SRS) resource set that includes a first SRS resource associated with a first SRS resource indicator (SRI) and a first antenna of the UE, and a second SRS resource associated with a second SRI and a second antenna of the UE. The UE may receive first downlink control information (DCI) that schedules a first uplink communication on a first uplink channel, wherein the first DCI indicates the first SRI. The UE may transmit, using the first antenna, the first uplink communication using a transmit power that is based at least in part on a weighted average of a first pathloss associated with the first antenna and a second pathloss associated with the second antenna. Numerous other aspects are described.

Power control for sounding reference signal resource indicator based antenna selection

Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

The UE may receive a tracking reference signal via the tracking reference signal port based on the antenna port mapping. The UE may perform a channel measurement procedure using the tracking reference signal based on the mapping.

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.

Method and apparatus for control signaling for SIC operation in 2-codeword operating mode. The apparatus transmits, to a network entity, a SIC capability indication comprising an indication that the UE supports a SIC operation for 2-CW allocation and an order of processing a first codeword and a second codeword. The apparatus monitors for an ACK to enable the SIC operation between the UE and the network entity. The apparatus receives downlink communication based on the SIC operation in response to receiving the ACK to enable the SIC operation. The apparatus may process the first codeword, within the downlink communication, transmitted based on a first MCS. The apparatus may cancel interference from the downlink communication based on the first codeword to obtain the second codeword, within the downlink communication, transmitted based on a second MCS.
