Abstract: A random access channel (RACH) procedure allows a user equipment (UE) to achieve synchronization with a network and obtain network resources and services from a scheduling entity. This disclosure provides various options for implementing a two-step RACH procedure that can support various UE behaviors in relation to using or not using a time symbol gap between a physical random access channel (PRACH) resource and a physical uplink control channel (PUCCH) resource.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that schedules a search space set; receive, on the search space set, first downlink control information (DCI) that schedules or configures one or more second DCIs that are multiplexed with one or more semi-persistent scheduling occasions; and process the one or more second DCIs based at least in part on the first DCI. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving, from a base station, a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, receiving, from the base station, the one or more repetitions of the downlink control channel, and combining the one or more repetitions of the downlink control channel to decode the downlink control channel. In another aspect, the network can transmit, to a user equipment (UE), a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, and transmitting, to the UE, the one or more repetitions of the downlink control channel over the resources.

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.
