Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a beam configuration for each physical cell identifier (PCI) of a set of candidate PCIs. A beam configuration for a PCI may include, for example, transmission configuration indicator (TCI) states for downlink channels and reference signals or spatial relations for uplink channels and reference signals. The UE may receive an indication of a selected subset of PCIs of the set of candidate PCIs. The UE may apply the beam configuration for each PCI of the selected subset of PCIs based on the indication of the selected subset of PCIs. The UE may then communicate according to the beam configurations for the selected subset of PCIs.

Abstract: Apparatus, methods, and computer program products for beam updating are provided. An example method includes receiving DCI. The method further includes determining, based on the DCI, whether the DCI is associated with a beam update for uplink, downlink, or a combination of the uplink and the downlink. The method further includes determining, from the DCI, a TCI state that indicates a beam for the uplink, the downlink, or the combination of the uplink and the downlink.

Abstract: Method and apparatus to defer transmission of HARQ-ACK feedback that overlaps a DL symbol. The apparatus determines to transmit PUCCH SPS HARQ-ACK feedback in response to a received semi-persistently scheduled PDSCH. The apparatus determines that the transmission of the SPS PUCCH HARQ-ACK feedback would overlap with a DL symbol. The transmission of the SPS PUCCH HARQ-ACK feedback is deferred to another UL symbol if the transmission of the SPS PUCCH HARQ-ACK feedback overlaps with the DL symbol. The apparatus transmits, based on the determination that the SPS PUCCH HARQ-ACK feedback would overlap with a DL symbol, a deferred SPS PUCCH HARQ-ACK feedback in one of a next set of available UL symbols or concurrently with a PUCCH HARQ-ACK feedback transmission in a next dynamically scheduled PUCCH after the DL symbol based on a deferred feedback configuration configured to define PUCCH content.

Abstract: Aspects relate to configuration of a combined reference signal configuration including two or more reference signal configurations. Each reference signal configuration may be associated with one or more beam identifiers (IDs) is a respective communication direction. In some examples, the communication direction may be a downlink communication direction, an uplink communication direction, or a sidelink communication direction. Based on the combined reference signal configuration, reference signals associated with the two or more reference signal configurations may be communicated between devices (e.g., between a user equipment (UE) and a network entity or between two UEs). In addition, a UE may transmit a measurement report based on one or more report settings configured for the combined reference signal configuration.

Abstract: A first network node may identify at least one of a usage probability or an interference probability of each Rx beam of the first network node in a plurality of Tx-Rx beam pairs associated with the first network node and the second network node. The usage probability may include a usage metric that indicates a likelihood of using a beam. The interference probability may include an interference metric that indicates a likelihood of a Tx beam of the second network node interfering with an Rx beam of the first network node. The first network node may transmit a first indication of the usage probability or the interference probability of each Rx beam in the plurality of Tx-Rx beam pairs. The second network node may receive the first indication and adjust a beam schedule for at least one of the plurality of Tx-Rx beam pairs based on the received first indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive configuration information, the configuration information indicating that a Layer 1 / Layer 2 (L1/L2) control signal is to be used to indicate when the network node is to: switch from additional transmission reception point (TRP) functionality to primary TRP functionality for a primary serving cell, or switch from a secondary serving cell to the primary serving cell and activate the primary TRP functionality. The network node may receive the L1/L2 control signal. The network node may activate, based at least in part on the L1/L2 control signal, the primary TRP functionality. Numerous other aspects are described.
