Abstract: Apparatus, methods, and computer program products for PHY priority for wireless communications are provided. An example apparatus may receive, from a base station, scheduling information for an uplink or downlink transmission indicating an uplink or downlink PHY priority level from a set of priority levels including a first half-duplex priority level, a second half-duplex priority level, a first full-duplex priority level, and a second full-duplex priority level. The example apparatus may transmit or receive the uplink or downlink transmission based on the uplink or downlink PHY priority level indicated by the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a transmission configuration indicator (TCI) state to use for communications with a network entity after switching between TCI modes (e.g., a joint TCI state mode and a separate TCI states mode for uplink transmission and downlink reception). A UE may autonomously switch between the TCI modes based on a trigger event, and may send an indication to a network entity of the trigger event prior to communicating. A UE may identify a TCI configuration with unconfigured power control parameters. The UE may determine a common power control configuration for communicating with a network entity based on applying a rule to the TCI configuration to determine the power control parameters.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for enabling downlink control information (DCI) based beam and path loss (PL) reference signal (RS) activation. An example method generally includes reporting, to a network entity, a capability of the UE to support at least one of downlink control information (DCI) based activation of at least one of beam switching, beam activation, or path loss (PL) reference signal (RS) activation; receiving, from the network entity, DCI activating at least one of the beam switching, beam activation, or PL RS; and performing the beam switching, beam activation, or PL RS measurement in response to the DCI.

Abstract: Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive transmission configuration indicator (TCI) information relating to a common beam TCI indication, the TCI information relating to a plurality of channels or reference signals. The UE may selectively transmit or receive one or more channels or reference signals of the plurality of channels or reference signals in accordance with the TCI information, based at least in part on whether the TCI information relating to the common beam TCI indication is usable for the one or more channels or reference signals of the plurality of channels or reference signals, wherein the one or more channels or reference signals are a proper subset of the plurality of channels or reference signals. Numerous other aspects are described.

Abstract: Methods, systems, and devices for enabling transitions between half-duplex and full-duplex modes in wireless communications are described. A user equipment (UE) may transmit to a base station a first indication of a switching latency for transitioning between a half-duplex mode and a full-duplex mode. The UE may receive, from the base station in accordance with the first indication of the switching latency, a second indication that the UE is to transition to one of the half-duplex mode or the full-duplex mode. The UE may transition to the half-duplex mode or the full-duplex mode based on receiving the second indication.

Abstract: Various aspects of the disclosure relate to distributed multiple-input multiple-output (MIMO) communication such as coordinated beamforming or Joint MIMO. In some aspects, distributed MIMO is used to support communication in a cluster of wireless nodes (e.g., access points). A distributed MIMO scheduling scheme as taught herein is used to schedule the wireless nodes (e.g., access points and/or stations) operating within the cluster. For example, selected stations may be triggered to communicate with respective access points.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a first carrier having a first subcarrier spacing (SCS), a scheduling indication via a physical downlink control channel (PDCCH) scheduling a downlink transmission on a second carrier having a second SCS. The UE may process the downlink transmission on the second carrier based at least in part on a delay between the PDCCH and the scheduled downlink transmission and a timing threshold having a basic term and an adjustment term. For example, the basic term may be based at least in part on a minimum delay between the PDCCH and the scheduled downlink transmission, and the adjustment term may be based at least in part on a processing time due to a difference between the first SCS and the second SCS. Numerous other aspects are provided.

Abstract: Aspects described herein relate to power control for uplink beam sweep. In one aspect, a network entity may determine a beam sweep pattern including one or more beams for a user equipment (UE), the beam sweep pattern associated with transmission on at least one of a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). The network entity may also transmit an indication including the one or more beams for the beam sweep pattern to the UE. In another aspect, a UE may receive an indication including a beam sweep pattern including one or more beams for transmission on at least one of a PUSCH or a PUCCH. The UE may perform beam sweep using one or more beams on at least one of the PUSCH or the PUCCH based on the beam sweep pattern.
