Abstract: Methods, systems, and devices for wireless communications are described to indicate a single frequency network (SFN) mode and associated composite channel reference signals to a user equipment (UE). A UE and a base station may communicate via two or more transmission and reception points (TRPs) using an SFN transmission, which may represent a transmission having multiple beam configurations. The base station may transmit a configuration associated with a control channel that explicitly or implicitly indicates whether control channel transmissions are associated with an SFN mode or are configured with multiple candidate beam configurations. The base station may transmit an indication of activated beam configurations for the control channel. The UE may receive one or more reference signals from each TRP and, based on the SFN indication, may use information from the one or more reference signals to receive the control channel transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from abase station, a sounding reference signal (SRS) configuration indicating a number of candidate slots for transmission of a multi-slot aperiodic SRS (A-SRS); receive, from the base station, an SRS trigger, the SRS trigger comprising an indication of an A-SRS resource set, the A-SRS resource set comprising a plurality of A-SRS resources corresponding to the number of candidate slots; and transmit, in response to the SRS trigger, the multi-slot A-SRS in one or more of a plurality of candidate slots using at least a portion of the A-SRS resource set. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting sounding reference signal (SRS) resources with frequency hopping. In some implementations, a user equipment (UE) may use different SRS ports, different antenna ports, different numbers and sizes of SRS resources, different periodicities, different offsets, different transmission comb values, different number of symbols, different power control parameters, and/or different transmission comb offset values for SRS transmissions on different frequency subbands of the frequency hopping pattern to ensure that sounding operations cover all antennas of the UE, cover the entire frequency range of interest, and provide sufficiently dense SRS transmissions from which a base station can determine the best channel for DL transmissions while also using a minimum amount of SRS resources and consuming minimal power in the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a UE may receive an indication of a set of sounding reference signal (SRS) parameters corresponding to a set of SRS resources for transmitting SRSs, where the set of SRS resources may refer to frequency, or time, or both. In some examples, the SRS parameters may include, among other examples, a frequency allocation, a frequency overlap parameter, a number of allocated symbols, a comb value, a cyclic shift, a comb offset, a frequency hopping parameter, a repetition parameter, a symbol grouping parameter, or any combination thereof. The UE may determine an SRS configuration for the one or more SRSs based on the set of SRS parameters and transmit the one or more SRSs based on the configuration. In some examples, the SRS configuration includes a configuration for SRS frequency hopping, or SRS repetition, or both.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication scheduling. An example method that may be performed by a user equipment (UE) includes receiving, from a base station, one or more configurations indicating wireless communication resources including at least one of a plurality of bandwidth parts (BWP) or a plurality of component carriers (CCs); receiving, from the base station, control signaling indicating a scheduling offset to communicate with the base station via at last one of the BWPs within at least one of the CCs; determining a value of the scheduling offset based at least in part on a minimum scheduling offset value; and taking at least one action in response to the determination.

Abstract: Aspects relate to wireless communication having sounding reference signal (SRS) power control using non-scheduling downlink control information (DCI) that is configured to trigger aperiodic SRS without scheduling data and without a channel state information (CSI) request. The non-scheduling is configured to include at least two transmit power control (TPC) commands A first TPC command is configured for power control of a physical uplink shared channel (PUSCH) transmitted by a UE to a base station. A second TPC command is configured for power control of one or more sounding reference signal (SRS) resource sets. Additionally, the first TPC command may be independent from the second TPC command where different power control is implemented for the PUSCH and the SRS transmissions. Additionally, the non-scheduling DCI may be formatted according to a DCI format 0_1 or a DCI format 0_2.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a medium access control (MAC) message indicating a switch to a multiple transmit receive point (M-TRP) transmission scheme. The UE may perform a communication using the M-TRP transmission scheme in accordance with the MAC message. Numerous other aspects are described.

Abstract: A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for a cell-group transmission power control (TPC) command that allows the base station to adjust the transmission power of uplink transmissions on multiple cells in order to mitigate cross-link interference. A UE may receive the cell-group TPC command as a single downlink control information (DCI) that indicates a plurality of TPC commands for a plurality of cells that are configured for the UE. The UE may adjust a transmit power for a respective uplink transmission for each respective cell of the plurality of cells based on a respective TPC command of the plurality of TPC commands.
