Abstract: Certain aspects of the present disclosure provide techniques for providing power control parameters for channels and/or reference signals sharing a same common transmission configuration indicator (TCI) state. A method that may be performed by a user equipment (UE) includes measuring a path loss at a user equipment, receiving, from a network, a plurality of power control configurations, wherein: each power control configuration of the plurality of power control configurations comprises a respective plurality of power control parameters, and each power control configuration of the plurality of power control configurations applies to a respective uplink channel or reference signal object associated with a common transmission configuration indication (TCI) state, and transmitting at least one uplink channel or reference signal object at a transmission power that is based on the measured path loss and at least one of the power control configurations of the plurality of power control configurations.

Abstract: Aspects described herein relate to communicating a beam report that includes beam measurements performed by one or more antenna panels and an identifier of the one or more antenna panels. The beam report may be used to determine a number of antenna panels supported by a user equipment (UE) transmitting the beam report, which may be used in configuring the UE for communicating with one or more other devices.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, on a downlink control channel and a first beam, first downlink control information (DCI), wherein the first DCI identifies a second DCI that is carried on a downlink shared channel; and receive multiple repetitions of the second DCI on the downlink shared channel on a plurality of second beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine whether to transmit a sidelink timing synchronization signal to a second UE based at least in part on a sidelink zone in which the first UE is located and a sidelink zone in which the second UE is located. The first UE may selectively transmit the sidelink timing synchronization signal to the second UE based at least in part on determining whether to transmit the sidelink timing synchronization signal to the second UE. Numerous other aspects are provided.

Abstract: Wireless communication devices, systems, and methods related to mechanisms for transmitting and receiving reference signals in a high-speed train (HST) single frequency network (SFN). A base station (BS) determines a first frequency pre-compensation value for a reference signal transmitted via a first transmission and reception point (TRP) and a second frequency pre-compensation value for a reference signal via a second TRP. The BS notifies a user equipment (UE) of the first and second pre-compensation values through at least one of the TRPs. The BS applies the first pre-compensation value to the reference signal via the first TRP and the second pre-compensation value to the reference signal via the second TRP. The UE adjusts its tracking loop for the reference signal based on the pre-compensation values, reducing estimation and/or search overhead at the UE.

Abstract: Certain aspects of the present disclosure provide techniques for determining default parameters to use in the absence of a signaled uplink transmission configuration indicator (TCI) state for uplink transmissions. In some cases, a UE may determine, based on one or more rules, at least one of a default uplink beam or default path loss reference signal (PL RS) to use an uplink transmission in the absence of a signaled uplink transmission configuration indicator (TCI) state for the uplink transmission; and send the uplink transmission in accordance with the determination.

Abstract: Certain aspects of the present disclosure provide techniques for increasing diversity of transmissions with slot aggregation using slot-specific cyclic delay diversity (CDD). A method that may be performed by a transmitting device includes determining to transmit a signal using cyclic delay diversity (CDD) in a plurality of slots; and transmitting the signal using a different cyclic delay in each slot of the plurality of slots.
