Abstract: This disclosure provides systems, methods and apparatuses for a selection of one or more transmission and reception points (TRPs) within a multi-TRP system. In one aspect, a user equipment (UE) may transmit an indication of the selected TRPs and an indication of one or more beams that the selected TRPs may use to communicate with the UE based on a mismatch between a default operating frequency (DOF) of each TRP within the multi-TRP system and a DOF of the UE. For example, the UE may receive an indication of a DOF of each antenna port of the TRPs within the multi-TRP system and the UE may compare the indicated DOFs with a DOF of each antenna module of the UE. The UE may select to communicate with TRPs and select one or more ports that the selected TRPs may use to communicate with the UE based on the comparison.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first wireless device may transmit, via a first beam, a first set of data and a first reference signal associated with the data on a data channel for beam refinement. The first wireless device may further transmit, via a second beam, a second set of data and a second reference signal on the data channel for beam refinement. A second device may receive the first set of data and first reference signal in addition to receiving the second set of data and second reference signal. The second device may transmit, to the first device, beam refinement feedback information for the first beam and the second beam based on receiving the first reference signal and the second reference signal on the data channel. Thus, the first device may refine beams based on a data transmission over a data channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may configure a group wake-up signal based at least in part on a sidelink zone identifier that corresponds to a geographical area. The base station may transmit the group wake-up signal to collectively wake up at least a subset of user equipments (UEs) that are located in the geographical area corresponding to the sidelink zone identifier. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station and a user equipment (UE) may utilize multi-port reference signals to determine a beam pair for rank-2 transmissions. For example, a UE may receive a set of multi-port reference signals, where each multi-port reference signal of the set corresponds to a unique beam pair and is received via two ports associated with two different polarizations. The UE may determine a spectral efficiency estimation for each multi-port reference signal of the set, select a beam pair associated with a multi-port reference signal with the highest determined spectral efficiency estimation of the set, and transmit an indication of the selected beam pair to the base station. Therefore, the UE and the base station may communicate using a beam pair which maximizes the spectral efficiency and rate of rank-2 transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit a set of reference signals spanning a channel to a user equipment (UE), where each of the reference signals is associated with one of a set of transmit beams. The UE may measure a signal quality of each of the set of reference signals. In some cases, each measured signal quality may correspond to one of a set of subbands of the channel and one of the set of transmit beams. The UE may then transmit an indication of at least one signal quality associated with one of the set of subbands and one of the set of transmit beams. In some cases, the UE may indicate the at least one signal quality according to a configuration that may be indicated by the base station or selected by the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a broadcast transmitter, a broadcast signal including one or more multi-resolution messages. The UE may decode at least one of the one or more multi-resolution messages based on receiving the broadcast signal from the broadcast transmitter, and may determine that a data rate associated with the broadcast signal is less than a threshold based on the decoding. The UE may transmit a signal querying the broadcast reception capability of a base station based on determining the data rate. In response to the query signal, the UE may receive a signal indicating a broadcast reception capability of the base station, and may communicate, with the base station, based on the broadcast reception capability of the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with other network devices as part of a wireless communications system. The UE may identify a blockage corresponding to one or more antenna arrays of a set of antenna arrays based on using a first set of beam weights, which may correspond to a static beamforming codebook of the one or more antenna arrays. The UE may switch from a static beamforming codebook-based beam weight determination to a dynamic beamforming codebook-based beam weight determination. The UE may then determine a second set of beam weights to use for the one or more antenna arrays based on the dynamic beamforming codebook-based beam weight determination. The UE may then communicate using the one or more antenna arrays according to the second set of beam weights.

Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for a selection of a set of beams that a first cell or a second cell, or both, may use to communicate with a user equipment (UE) within a carrier-aggregation (CA) or dual-connectivity (DC) deployment. In one aspect, the UE may transmit an indication of the selected set of beams based on a mismatch between a default operating frequency (DOF) of antenna ports of each cell and antenna modules of the UE. For example, the UE may receive an indication of a DOF of each antenna port of the first cell and the second cell and the UE may compare the indicated DOFs with a DOF of each antenna module of the UE. The UE may select one or more ports that each cell may use to communicate with the UE based on the comparison.
