Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit, to a base station, a UE capability message indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation procedure associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation procedures, each procedure associated with a respective subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive, from the base station, one or more downlink signals via one or more downlink beams based on the indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., an active) demodulation mode.

Abstract: Aspects relate to sounding on a subset of available sounding resources. A user equipment (UE) may transmit a sounding reference signal (SRS) on a subset of the frequency resources available for a hop of an SRS hopping sequence. A UE may be configured to use a subset of frequency resources or the UE may autonomously identify this subset. A base station may send a bit map to a UE to indicate the subset of resources to use for a hop. Each bit of the bit map may indicate that the UE is to transmit an SRS on a particular RB or on a particular groups of RBs. The same subset of resources may be designated for each hop or different subsets of resources may be designated for different hops. An indication of the subset of resources may be provided for each hop. The subset of resources may be cycled for different hops.

Abstract: Aspects relate to wireless communication for slot postponing of aperiodic sound reference signals (A-SRS) by a user equipment in a wireless network. A network node, such as a gNodeB, may send at least a portion of a slot postponing configuration for transmission of aperiodic sounding reference signals (A-SRSs) to a user equipment (UE). In a particular aspect, the slot postponing configuration is established through RRC signaling and does not utilize downlink control information (DCI) or MAC-CE sent parameters for establishing the slot postponing configuration. The slot positioning configuration is used to control slot offset postponing, the number of slot offsets, the number of times transmission of A-SRS can be postponed in the UE, and priority rules based on the postponing configuration.

Abstract: A sidelink network is disclosed that provides a duplex mode indication as well as a duplex mode switching and coordination for a sidelink network device. The duplex mode indication controls the duplex mode switching by the sidelink network device between a half-duplex mode and a full-duplex mode of communication. The resulting control of the duplex mode switching reduces blocking and reduces power consumption.

Abstract: A method of wireless communication performed by a user equipment (UE) includes: receiving a cell configuration associated with a cross-link interference sounding reference signal (CLI-SRS) timing; and transmitting, based on the CLI-SRS timing and a CLI-SRS priority configuration, a first communication at a first time period. A second communication may be scheduled for at least a portion of the first time period, and one of the first communication or the second communication may include a CLI-SRS.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing uplink control information on physical uplink shared channels in full duplex mode. An example method that may be performed by a UE includes: receiving scheduling information from a network entity, wherein: the scheduling information schedules, in a first full duplex (FD) slot of a plurality of slots, transmission of a first uplink (UL) data channel repetition of a plurality of UL data channel repetitions and uplink control information (UCI), and the FD slot comprises an UL subband for UL transmissions and a downlink (DL) subband for DL transmissions, multiplexing the first UL data channel repetition with the UCI to form a multiplexed transmission, and transmitting the multiplexed transmission in the FD slot.

Abstract: Aspects of the present disclosure provide techniques for wireless communication. A method by a user equipment (UE) includes receiving scheduling information from a network entity. The scheduling information schedules transmission of a first uplink (UL) channel repetition of a plurality of UL channel repetitions in a first full duplex (FD) slot of a plurality of slots. Additionally, the first UL channel repetition is associated with one or more time domain resource allocations (TDRAs) and one or more frequency domain resource allocations (FDRAs). Additionally, based on the one or more FDRAs associated with the first UL channel repetition, a portion of the first UL channel repetition is scheduled to occur in a downlink subband of the first FD slot. The method also includes taking one or more actions to transmit the first UL channel repetition based on the scheduling information.

Abstract: Aspects of the disclosure relate to the use of enhanced downlink control information to communicate partial frequency sounding configuration to user equipment (UE). A UE may receive a partial frequency sounding configuration generated for the UE the downlink control information, transmit a sounding reference signal (SRS) in one or more resources configured for SRS transmission in a bandwidth used by the UE, the one or more resources being identified by the partial frequency sounding configuration, and refrain from transmitting in a portion of a set of resources configured for SRS transmission in the bandwidth used by the UE. A format for the enhanced downlink control information may be based on standards defined the downlink control information formats.
