Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may monitor a set of operational conditions associated with the UE. Based on the monitoring, the UE may transmit a request for an indication identifying a PDCCH monitoring location associated with receiving a next DCI communication. A base station may receive the request and determines whether to grant the request. Based on the determination, the base station may selectively transmit the indication to the UE. The UE may monitor in the PDCCH monitoring location if the indication is received in response to the request.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may store configurations for candidate physical cell identifiers (PCIs) that the UE may select from for inter-cell mobility. A base station or a UE or both may identify a first configuration indicating a number of configured PCIs for inter-cell mobility operations. The base station or the UE or both may identify a second configuration indicating a number of selected PCIs for inter-cell mobility operations. In some cases, the selected PCIs may be a subset of the configured PCIs. Identifying the number of configured PCIs and the number of selected PCIs by the base station and UE may be based on a capability report configured by the UE. The UE and the base station may perform an inter-cell mobility operation based on stored cell configurations associated with the configured PCIs and the selected PCIs.

Abstract: Apparatus, methods, and computer-readable media for facilitating per bandwidth part TCI state or spatial relation are disclosed herein. For example, aspects disclosed herein provide techniques for enabling a UE (e.g., a reduced capability UE) to associate at least one of a TCI state or a spatial relation with respective hopping regions. An example method for wireless communication at a UE includes determining, while communicating using a first frequency range comprising a first set of frequency hops, at least one of a TCI state or a spatial relation for communicating using a second frequency range comprising a second set of frequency hops. The example method also includes communicating, after switching communication from the first frequency range to the second frequency range, using the second frequency range based on the determined at least one of the TCI state or the spatial relation.

Abstract: Methods, systems, and devices for wireless communication are described. A first network node may receive information via a first cell. The information may indicate a resource allocation for transmission of an initial uplink message via a second cell. The initial uplink message is a first uplink transmission scheduled to occur between the first network node and a second network node after a handover of the first network node from the first cell to the second cell. The first network node may receive a command via the first cell. The command may trigger the handover of the first network node from the first cell to the second cell. In response to the command message, the first network node may transmit the initial uplink message via the second cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may identify a plurality of cells associated with serving a user equipment (UE), where each cell of the plurality of cells has been either selected for serving the UE or deselected for serving the UE. The first wireless communication device may transmit an indication of the plurality of cells associated with serving the UE to a second wireless communication device, where the indication includes information indicating whether each cell of the plurality of cells has been selected for serving the UE or has been deselected for serving the UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a first reported beam switch timing value and a second reported beam switch timing value. The UE may receive downlink control information (DCI) associated with an aperiodic channel state information reference signal (CSI-RS). The UE may receive the aperiodic CSI-RS based at least in part on applying a beam indicated in the DCI in accordance with one of the first reported beam switch timing value or the second reported beam switch timing value being based at least in part on one or more of whether tracking reference signal (TRS) information is configured for the UE or whether a repetition is associated with the aperiodic CSI-RS. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes determining at least one reference signal (RS) associated with a first cell that is configured without a control-resource set (CORESET). The method also includes monitoring the at least one RS associated with the first cell. The method further includes detecting a beam failure on the first cell based on the monitoring of the at least one RS.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.
