Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may receive a configuration from a base station (BS). The configuration may indicate transmission parameters associated with different symbols such as sub-band full duplex (SBFD) symbols and non-SBFD symbols. For example, the transmission parameters may indicate power control parameters (e.g., a received power target value, a power control factor value, a closed-loop power control value) and a unified transmission configuration indicator (TCI) (e.g., a joint uplink and downlink TCI state, separate uplink and downlink TCI states). The UE may transmit uplink transmissions to the BS, in accordance with the transmission parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that configures one or more sounding reference signal (SRS) resource sets that includes one or more SRS resources associated with a full duplex (FD) set of symbols and one or more SRS resources associated with a non-FD set of symbols. The UE may receive at least one of a radio resource control communication or a downlink control information communication indicating at least one of the one or more SRS resources that are to be used for an uplink transmission repetition. The UE may transmit the uplink transmission repetition in one of: only the FD set of symbols, only the non-FD set of symbols, or both the FD set of symbols and the non-FD set of symbols. Numerous other aspects are described.

Abstract: Aspects of this disclosure provide methods, devices and systems for concurrently transmitting control information and data information. In some more specific aspects, a base station may transmit one or more parameters to a user equipment (UE) that indicate to the UE to refrain from transmitting uplink control information together with uplink data information in an uplink data channel. Instead, the one or more parameters may configure the UE to transmit the uplink control information and the uplink data information using overlapping resources in different channels. In some more specific aspects, the UE may transmit the uplink control information in a slot of an uplink control channel and transmit the uplink data information in a slot of the uplink data channel that at least partially overlaps with the slot of the uplink control channel.

Abstract: Apparatus and method for multi-PUSCH repetitions with joint channel estimation The apparatus receives, from a base station, a joint channel estimation configuration and at least one of a frequency hopping configuration or a beam mapping configuration. The apparatus receives DCI scheduling a plurality of PUSCHs having multiple repetitions. The apparatus applies a frequency hopping configuration or a beam mapping configuration based on the joint channel estimation configuration and at least one of a received frequency hopping configuration or a received beam mapping configuration. The apparatus communicates, with the base station, based on the received frequency hopping configuration or the received beam mapping configuration. The apparatus maintains phase continuity across one or more TBs scheduled by the DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point (TRP), a downlink control information (DCI) communication, the UE being included in a multi-TRP configuration with the first TRP and a second TRP. The UE may determine information unique to the first TRP. The information unique to the first TRP may be at least one of associated with the DCI communication or included in the DCI communication. The UE may generate a downlink scrambling sequence initialization code, associated with the first TRP, based at least in part on the information unique to the first TRP.

Abstract: Various aspects relate generally to sounding reference signal (SRS) reference indicators (SRIs) indicating an SRS associated with a transmission configuration to use for transmission of a data channel communication. Some aspects more specifically relate to an SRI indicating an SRS from an SRS resource having a same duplexing type as a slot in which the data channel communication is scheduled. In some aspects, the SRI may indicate an SRS from an SRS resource that is not a most-recent SRS resource based on the most-recent SRS resource having a different duplexing type than the slot in which the data channel communication is scheduled.

Abstract: Methods, systems, and devices for wireless communications are described. One or more user equipment (UEs) and network entities may communicate signaling using an SRS hopping scheme based on a numerical quantity of orthogonal frequency division multiplexing (OFDM) symbols in each set of OFDM symbols in a sounding reference signal (SRS) resource. Additionally, or alternatively, the UEs and the network entities may communicate signaling using a power normalization factor that depends on the numerical quantity of OFDM symbols and a numerical quantity of antenna ports for the SRS. In some examples, a network entity may indicate the numerical quantity of antenna ports, the numerical quantity of OFDM symbols in each OFDM symbol set, or both to a UE in control signaling. The UE may transmit the SRS to the network entity using the SRS resource and in accordance with the SRS hopping scheme, the power normalization factor, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may receive an indication of a detection of a scheduling collision of a first scheduled communication of a first scheduling message from the first TRP and a second scheduled communication of a second scheduling message from a second TRP. The first TRP may back off from transmitting the first scheduled communication based at least in part on the indication. Numerous other aspects are described.
