摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to report feedback to a base station to address polarization impairments in multiple-input multiple-output (MIMO) communications. The UE and the base station may establish a communications link using a pair of orthogonally polarized beams, where the pair of polarized beams may be selected based on a beam sweep procedure. The UE may transmit a report to the base station indicating one or more polarization parameters associated with beam pairs identified in the beam sweep procedure, such as one or more orthogonality parameters, one or more polarization parameters relating to one or more beam pairs, or one or more angular spread parameters. Based on the report, the base station may transmit a beam configuration to the UE for polarization MIMO communications.

摘要： Method and apparatus for a UE to request a TCI state switch for blockage conditions. The apparatus predicts a blockage condition to a first beam communicating with a network node. The apparatus transmits, to the network node, a beam switch indication indicating a scheduled change in a TCI state mapped from the first beam to a second beam in response to the predicted blockage condition. The apparatus may schedule a beam change to the second beam based on the predicted blockage condition. The apparatus may correlate a beam change to the second beam at the UE with a corresponding beam change at the network node.

摘要： A configuration for inter-cell interference coordination in wireless communication systems. The apparatus determines a priority order of a first base station to schedule a first transmission with a first UE. The apparatus transmits a first transmission request to the first UE to schedule the first transmission. The apparatus receives, from the first UE, a measurement report based on the first transmission request received by the first UE, the measurement report indicates a signal quality of the first transmission request. The apparatus determines to schedule the first transmission with the first UE based at least on the measurement report. The apparatus sends a schedule indication to at least a second base station indicating whether the first transmission is scheduled with the first UE, at least the second base station has a lower priority order than the first base station.
