Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for power control in FD systems based on a PL-RS for measuring self-interference. In aspects, a base station may configure a PL-RS for one or more beam pairs and schedule a DL transmission including the PL-RS. A UE may measure self-interference corresponding to the one or more beam pairs based on the PL-RS and adjust an UL Tx power for a FD operation based on the self-interference measured for the one or more beam pairs. The UE may subsequently transmit an UL transmission for the FD operation based on the adjustment to the UL Tx power, such that the base station may receive an UL transmission having an UL Tx power that is based on the measured self-interference associated with the PL-RS.

Abstract: A method of wireless communication receives multiple beams from a base station. The method also simultaneously reports a signal to interference plus noise ratio (SINR) for multiple beams with a single channel measurement resource (CMR) and a single interference measurement resource (IMR). The single IMR is configured for multiple interference sources. A method of wireless communication by a base station configures a UE with a group of interference sources. The base station also configures the UE with an interference measurement resource associated with the group of interference sources.

Abstract: A method of wireless communication by a base station detects a UE is in a high speed train scenario. The method also instructs the UE to enter a high speed train (HST) mode when the UE is detected to be in the high speed train scenario. The method further performs beam management in accordance with the HST mode. A UE (user equipment) for wireless communication detects when the UE is in high speed train scenario. The UE also reports the high speed train scenario to a base station and then receives instructions from the base station to enter a high speed train (HST) mode. The UE performs beam management in accordance with the HST mode.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus can receive SSB grouping information associated with one or more SSB groups, each of the one or more SSB groups including one or more TRPs. The apparatus can also receive at least one of TCI information or QCL information, each of the TCI information and the QCL information indicating an SSB of the one or more SSB groups that is associated with a downlink Tx beam for downlink data or an uplink Rx beam for uplink data. Additionally, the apparatus can communicate the downlink data from or the uplink data to TRPs in a same SSB group or TRPs in different SSB groups based on at least one of the SSB grouping information, the TCI information, or the QCL information.

Abstract: A configuration for configuring and updating the spatial relationship of multiple physical uplink control channel (PUCCH) resources in a single message, thereby reducing signaling overhead. A user equipment (UE) constructs a message associated with at least one of a plurality of component carriers (CCs) or a plurality of bandwidth parts (BWPs) indicating a same spatial relation for the at least one of the plurality of CCs or the plurality of BWPs. The UE transmits the message to a base station. The base station transmits a message to the UE configuring multiple spatial parameters for the at least one of the plurality of CCs, the plurality of BWPs, or a plurality of uplink/downlink resources.

Abstract: Various aspects of the present disclosure generally relate to techniques for set based beam reporting. In some aspects, a user equipment (UE) may receive, from a base station, an indication of one or more sets of candidate beams, where each set of candidate beams includes a first beam combination and a second beam combination. The first beam combination may include a first beam as a channel measurement resource (CMR) and a second beam as an interference measurement resource (IMR), and the second beam combination may include the second beam as a CMR and the first beam as an IMR. The UE may determine measurement values for beam combinations in the sets and determine a candidate set to report based at least in part on the measurement values. The UE may transmit a measurement report with measurement values for the first and second beam combinations of the candidate set.
