Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, downlink control information (DCI) that includes a semi-persistent scheduling (SPS) activation indication. The UE may receive, from the network node, an SPS physical downlink shared channel (PDSCH) based at least in part on the SPS activation indication, wherein the SPS PDSCH is associated with one or more transmission parameters that are based at least in part on an antenna adaptation configuration applicable to the SPS PDSCH. Numerous other aspects are described.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE) device, control information indicating a condition associated with a demodulation reference signal (DMRS) grouping characteristic of a DMRS that is to be wirelessly communicated using one or more physical (PHY) channels. The method further includes performing the wireless communication based on the DMRS grouping characteristic indicated by the control information. The wireless communication is performed in response to detecting, by the UE device, that a first full duplex resource configuration associated with a first slot of a plurality of slots of a wireless communication and a second full duplex resource configuration associated with a second slot of the plurality of slots satisfy the condition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a downlink transmission in a downlink resource of a first bandwidth part (BWP) associated with a first time division duplexing (TDD) pattern. The UE may transmit, to the base station based at least in part on the downlink transmission, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback on a physical uplink control channel (PUCCH) resource of the first BWP or of a second BWP associated with a second TDD pattern. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a channel state information report in a subband full duplex slot using a first guard band. The UE may receive a physical downlink shared channel (PDSCH) communication. The UE may transmit an indication of an adjustment, based at least in part on the PDSCH communication, to use for a second guard band with respect to the first guard band. Numerous other aspects are described.

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: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select an uplink transmission power sharing configuration to use for transmission of one or more uplink messages. The uplink transmission power sharing configuration may be based on a first uplink transmission power capability of a first radio frequency (RF) chain of the UE and on a second uplink transmission power capability of a second RF chain of the UE. The UE may transmit the one or more uplink messages to a network entity in accordance with the uplink transmission power sharing configuration. Specifically, the UE may transmit the one or more uplink messages via the first RF chain using a first transmission power, and may transmit the one or more uplink messages via the second RF chain using a second transmission power that is different from the first transmission power.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives signaling configuring the UE with a control resource set (CORESET) activated with two transmission configuration indicator (TCI) states. The UE further receives a downlink control information (DCI) triggering transmission of aperiodic channel state information (CSI) reference signals (RSs) on aperiodic CSI-RS resources. The UE applies a quasi-colocation (QCL) assumption of at least one of the two TCI states for processing the aperiodic CSI-RSs, when a scheduling time offset is less than a threshold value and depending on whether same or different aperiodic CSI-RS resources are received from two transmission reception points (TRPs) associated.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, the method may include a user equipment (UE) transmitting, to a base station, first reference signals. The base station may perform channel estimation using the first reference signals and estimate a value for an uplink channel based on the channel estimation. The base station may generate second reference signals such that a characteristic of a downlink channel seen by the UE is within a target value and transmit the second reference signals to the UE. The UE may estimate a value for the characteristic of the downlink channel and obtain the target value from the estimated value. Both the UE and the base station may generate a secret using the target value and utilize the secret key for physical layer protection.
