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 a physical sidelink shared channel (PSCCH) transmission that uses unlicensed spectrum. The UE may select a resource block (RB) configuration for one or more resource blocks (RBs) that are associated with a physical sidelink feedback channel (PSFCH) transmission, the RB configuration being based at least in part on the unlicensed spectrum. The UE may transmit an acknowledgement (ACK)/negative acknowledgement (NACK) response to the PSCCH transmission based at least in part on using the PSFCH and the RB configuration for the one or more RBs. Numerous other aspects are described.

Abstract: Aspects are provided for enhancing HARQ ACK for Message 4 or Message B. An apparatus may obtain a configuration indicating a number of repetitions for a physical uplink control channel (PUCCH) transmission in a plurality of slots prior to activation of a dedicated PUCCH resource configuration with a plurality of repetitions based on a radio resource control (RRC) message. The PUCCH transmission includes a Hybrid Automatic Repeat Request (HARQ) feedback message in response to receiving a message on a Physical Downlink Shared Channel (PDSCH) in a random access procedure. The PUCCH transmission may then be transmitted on a PUCCH according to the number of repetitions. This allows coverage techniques to be applied to certain transmissions in order to improve coverage and reliability. In an aspect, the coverage enhancement techniques may include repetition of a transmission for coverage extension.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform early measurement report (EMR) measurements for a first set of carriers in an EMR time window. The UE may perform at least one verification operation for the EMR measurements based at least in part on at least one carrier measurement in a verification time window. The UE may transmit, to a network node, measurement results associated with the EMR measurements for one or more carriers in the first set of carriers based at least in part on the at least one verification operation. 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 monitor a configured set of control channel elements (CCEs) for physical downlink control channel (PDCCH) decoding for a scheduled cell of a set of scheduled cells, wherein the configured set of CCEs is on a per scheduled cell basis or a per carrier indicator field value basis. The UE may decode downlink control information (DCI) in one or more CCEs of the monitored configured set of CCEs. Numerous other aspects are described.

The UE may transmit, to the serving node of the NTN, uplink signaling based at least in part on a reference timing for the uplink signaling, wherein the reference timing for the uplink signaling is based at least in part on a reference timing of a downlink signaling and the one or more TA values, wherein the one or more TA values include a UE-specific TA value, and wherein a reference timing of the UE-specific TA value is for: a first propagation delay on a service link between the UE and a satellite associated with the NTN, and a second propagation delay on the service link. Numerous other aspects are described.
