Abstract: Techniques, systems, and devices for wireless communications are described. A user equipment (UE) may be in communication with a first and second transmitting device (e.g., by sidelink communication links). The UE may receive, from the first transmitting device, a first reference signal on a first set of resources. The UE may additionally receive, from the second transmitting device, a second reference signal on a second set of resources that overlap in the time domain with the first set of resources. In some cases, the first and second set of resources may additionally overlap in the frequency domain. The UE may determine synchronization information for time tracking or frequency tracking of sidelink communications with the first and second transmitting devices based on the first and second reference signals. The UE may communicate with the first and second transmitting devices based on the synchronization information for time tracking or frequency tracking.

Abstract: A user equipment (UE) transmits capability information to a base station indicating a first number of active transmission configuration indication (TCI) states or active spatial relations supported by the UE per group of bandwidth parts (BWPs) or per group of component carriers (CCs) for use in receiving control information or data. The UE receives, from the base station, a configuration of a second number of active TCI states or active spatial relations for the group of BWPs or the group of CCs that is limited to be less than or equal to the first number of active TCI states or active spatial relations supported by the UE. The UE monitors for downlink communication based on the second number of active TCI states. The UE uses the active spatial relations for uplink transmissions.

Abstract: The present disclosure provides signaling for multi-panel user equipment (MPUE) activation and deactivation status. The MPUE may include a plurality of panels. The MPUE may determine a number of active panels. The MPUE may transmit a status message indicating at least the number of active panels to a base station. The base station may schedule a communication with the UE for at least one panel of the number of active panels. The MPUE may receive from the base station, a downlink control information (DCI) scheduling a communication for at least one of the number of active panels. The MPUE may communicate according to the DCI using the at least one panel scheduled by the DCI. In another aspect, the MPUE may indicate a nominal number of active panels and implicitly manage a mapping of panel identifiers to an actual number of active panels.

Abstract: To provide a more robust connection and better coverage, a UE may be configured to receive an SFN PDSCH through a plurality of beams from a plurality of TRPs including a first TRP and a second TRP, the plurality of beams being based on configured DL TCI states. The UE may be further configured to transmit a same PUSCH through each of the plurality of beams. In addition, the same PUSCH may be transmitted through a first beam of the plurality of beams n times, and transmitted through a second bream of the plurality of beams m times, where n and m are integers greater than or equal to one.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate to a UE a first set of uplink power control parameters associated with half-duplex communications and a second set of uplink power control parameters associated with full-duplex communications. Alternatively, the base station may indicate the first set of uplink power control parameters and a set of power offsets associated with full-duplex communications. The base station may indicate a first set of resources associated with the first set of uplink power control parameters and a second set of resources associated with the second set of uplink power control parameters or the set of power offsets. In response, the UE may transmit one or more uplink messages over one or more resources of the second set of resources in accordance with the second set of uplink power control parameters or the set of power offsets.

Abstract: The present disclosure provides signaling for multi-panel user equipment (MPUE) activation and deactivation status. The MPUE may include a plurality of panels. The MPUE may determine a nominal number of active panels. The MPUE may map a number of panel identifiers equal to the nominal number of active panels to an actual number of active panels of the plurality of panels. The MPUE may receive, from a base station, a downlink control information (DCI) scheduling a communication based on one of the panel identifiers. The MPUE may determine a panel for the communication based on the mapping. The MPUE may communicate according to the DCI using the determined panel.
