Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a physical layer measurement on a non-serving cell of the UE. The UE may report a measurement value of the physical layer measurement to a serving cell of the UE based at least in part on the physical layer measurement satisfying a threshold. The UE may receive, based at least in part on reporting the physical layer measurement, a physical layer reference signal measurement configuration for the non-serving cell. The UE may transmit a measurement report based at least in part on the physical layer reference signal measurement configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for precoding for multi-panel uplink transmission. For codebook-based uplink transmission, a user equipment (UE) can determine one or more preferred or selected precoders for uplink transmission. The precoders can be from an expanded UE codebook that maps a first number of transmit layers at the UE to a second number of antenna ports at the UE, the layers and/or antenna ports associated with multiple uplink transmit panels at the UE. The UE sends an indication to a base station (BS) of the determined precoders and/or sends an uplink transmission using the determined precoders. For non-codebook based uplink transmission the UE receives first and second reference signals (RSs), from first and second ports of a BS, with first and second UE antenna panels. The UE computes precoders to use for uplink transmission based on the RSs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, during a transmission interval, a data transmission over a plurality of beamformed channels and, for each data transmission, a reference signal transmitted in conjunction with the data transmission. The UE may perform, for one or more of the plurality of beamformed channels, a channel state measurement procedure during the transmission interval using the data transmission, the reference signal, or a combination thereof. The UE may transmit, over an acknowledgement/negative acknowledgement (ACK/NACK) signal, a feedback report indicating a result of the channel state measurement procedure for the one or more of the plurality of beamformed channels. The base station may perform, based at least in part on the feedback report, subsequent transmissions to the UE over the one or more beamformed channels.

Abstract: This disclosure provides methods, devices and systems related to UE-aided selective single frequency network (SFN). In some implementations, a UE may obtain a first channel measurement of a first communication channel associated with a serving transmission and reception point (TRP), and a second channel measurement of a second communication channel associated with a neighbor TRP. The UE may further select an SFN condition associated with the first channel measurement or the second channel measurement, and transmit an indication including the SFN condition to one or both of the serving TRP or the neighbor TRP. In some other implementations, a network entity may select whether to configure a transmission scheme according to SFN for at least one of a serving TRP and a neighbor TRP associated with the SFN condition, and communicate with the UE associated with the transmission scheme according to SFN.

Abstract: User equipment (UE) based beam selection for beam failure recovery operations are disclosed. A method of wireless communication includes: identifying a beam failure event associated with a first beam and a secondary cell and transmitting a beam failure recovery request for the secondary cell. The method further includes selecting a second beam for secondary cell communications prior to receiving a response to the beam failure event, and transmitting or receiving a communication to or from the secondary cell using the selected second beam.

Abstract: A UE may determine that two or more resources on two or more beams from a base station have phase continuity. The UE may determine, based on the two or more resources on the two or more beams having the phase continuity, a joint channel information associated with the two or more beams using individual measurements respectively corresponding to the two or more beams. The UE may then transmit, to the base station, a group-based beam report including the joint channel information. The base station may provide the UE with an indication that the two or more resources on the two or more beams from the base station have phase continuity. The base station may receive the group-based beam report from the UE based on the indication, and the base station may configure communication with the UE on a joint channel based on the group-based beam report.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for applying a common beam for multiple signals to a default beam for a physical downlink shared channel (PDSCH). An example method generally includes receiving, from a network entity, configuration information, identifying a common beam for wireless communications between the UE and the network entity based on the received configuration information, identifying a default beam based, at least in part, on the common beam and one or more rules, and receiving a physical downlink shared channel (PDSCH) by using the identified default beam.

Abstract: Certain aspects of the present disclosure provide techniques for applying uplink transmission configuration indicator (TCI) states with downlink reference signals to codebook based physical uplink shared channel (PUSCH) transmissions. An example method generally includes receiving, from a network entity, signaling of an uplink transmission configuration indicator (TCI) state with a target codebook based uplink transmission signal, determining if the TCI state has a source downlink reference signal (RS) and deciding how to process the codebook based uplink transmission based on the determination.
