Abstract: Aspects of the present disclosure relate to a technique for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). A user equipment (UE) may receive and/or detect a downlink control information (DCI) that schedules at least one dynamic CORESET and indicates a TCI state from a list of one or more TCI states for the dynamic CORESET. The UE may apply the indicated TCI state for processing physical downlink control channel (PDCCH) transmissions in the dynamic CORESET when one or more conditions are met.

Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Certain aspects of the present disclosure provide techniques for signaling quasi-coloration (QCL) information for demodulation reference signals (DM-RS) associated with multiple transmission-reception points (multi-TRP). An example method generally includes generating quasi-colocation (QCL) information indicating a first QCL assumption for a first group of demodulation reference signal (DM-RS) ports and a second QCL assumption for a second group of DM-RS ports; and transmitting the QCL information to at least one user equipment (UE) for use in processing one or more transmission associated with at least one of the first group of DM-RS ports and the second group of DM-RS ports.

Abstract: An antenna adaptation is provided for a communication node as controlled by a antenna adaptation command. The antenna adaptation command adjusts the number of active transmit antennas and/or the number of active receive antennas in the communication node such as for reducing interference at the communication node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a collision between a first uplink transmission and a second uplink transmission, wherein the first uplink transmission is a high priority uplink transmission and the second uplink transmission is a low priority uplink transmission; and cancel the second uplink transmission during a defined time period, wherein the defined time period has an end point based at least in part on a processing time and an offset, and a start point based at least in part on a triggering event for the first uplink transmission or a UE capability. 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 identify one or more overlaps between a first set of uplink transmissions on one or more master cell groups (MCGs) and a second set of uplink transmissions on one or more secondary cell groups (SCGs), wherein the first set of uplink transmissions are associated with respective first priority levels and the second set of uplink transmissions are associated with respective second priority levels; determine a power sharing configuration for the first set of uplink transmissions and the second set of uplink transmissions; and drop one or more transmissions, of at least one of the first set of uplink transmissions or the second set of uplink transmissions, based at least in part on the respective first priority levels and the respective second priority levels. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a message type for a random access message associated with a two-step random access channel procedure. The message type may be either a first message type or a second message type that is different from the second message type. The message type may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The user equipment may transmit the random access message based at least in part on the determined message type. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration associated with a layer to reference signal port mapping. In some cases, the UE may identify, based at least in part on the configuration, that at least one layer of a set of layers for receiving a downlink transmission from the base station is adapted based on at least one interference layer. In some cases, the adapted layer may be mapped to one or more reference signal ports. The UE may receive the downlink transmission and may decode the downlink transmission based on identifying that the at least one layer is adapted and the layer to reference signal port mapping.

Abstract: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.
