Abstract: Methods, systems, and devices for wireless communications are described. A UE may communicate with a set of transceiver nodes (e.g., transmission reception points (TRPs)) in a first transceiver node operation mode (e.g., a multi-TRP mode). A first transceiver node of the set of transceiver nodes may receive, from a second of the set of transceiver nodes, an indication to switch between rate matching states. The first transceiver node may switch from a first rate matching state to a second rate matching state and may transmit a downlink shared channel based on a resource configuration associated with the second rate matching state. The UE may receive the shared channel based on an antenna port configuration determined by the UE based on the first transceiver node operation and rate matching information. The rate matching information may be provided by the first transceiver node.

Abstract: Aspects are provided which allow a first wireless device such as a UE or base station to prioritize beams which are simultaneously received from or transmitted to cells of different numerologies or which are asynchronous to each other. The device determines an overlap in time between a first signal from a first cell and a second signal from a second cell, where the second cell includes at least one of a different numerology than the first cell or an asynchronous timing relative to the first cell. The device applies a beam prioritization rule for selecting a beam associated with the first signal or the second signal carrying information in separate beams. The device transmits information to or receives information from a second wireless device based on the selected beam. Thus, simultaneous beam conflict resolution may be improved for cells having different numerologies or asynchronous timing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted by a base station. The UE may receive system information that includes reconfigurable intelligent surface (RIS) or repeater assisted initial access information that identifies a set of SSBs that are associated with an RIS or a repeater and a modulation signature associated with the RIS or the repeater. The UE may selectively perform initial access using the SSB or search for another SSB based at least in part on the RIS or repeater assisted initial access information. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a recommended configuration for a configured grant that is to be received, at least in part, via radio resource control messaging. The UE may transmit, to a base station, one or more messages indicating the recommended configuration for the configured grant at the UE. The one or more messages may include at least one of a configured grant-specific scheduling request or a configured grant-specific control element. In some cases, at least one of the configured grant-specific scheduling request or the configured grant-specific control element may be formatted for association with grants that are received, at least in part, via radio resource control messaging. The UE may receive, from the base station, a configuration for the configured grant based on the recommended configuration.

Abstract: Positioning of a target user equipment (UE) using a mobile anchor node is supported by providing motion information for the mobile anchor node and/or measurement restrictions. The target UE receives motion information for the mobile anchor node, which may be an ordered list of points or, e.g., a motion path. The target UE may generate positioning measurements using the motion information for the mobile anchor node to determine the position of the mobile anchor node when it transmits positioning reference signals (PRS). The target UE may receive an indication of position measurement restriction if the mobile anchor node is moving. The target UE may receive PRS over a plurality of PRS occasions. The target UE may restrict measurement to only one PRS occasion, may generate and separately report measurements for each PRS occasions or may combine a plurality of measurements using filter coefficients provided by a location server.

Abstract: An example wireless communication device includes one or more processors, one or more transceivers, and memory. The one or more processors are configured to cause the wireless communication device to receive a respective reference signal from each of a plurality of transmission reception points (TRPs). The one or more processors are configured to cause the wireless communication device to transmit a first message comprising a recommended set of TRPs from among the plurality of TRPs for use in coherent joint transmission (CJT) based on the respective reference signals. The one or more processors are configured to transmit a second message comprising a channel state information (CSI) report based on a transmission hypothesis. The transmission hypothesis is based on the recommended set of TRPs or an override set of TRPs from among the plurality of TRPs for use in CJT.
