Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive radio link control (RLC) protocol data units (PDUs) within a receive window. Additionally, the UE may receive an uplink grant indicating a set of resources. Based on the set of resources, the UE may transmit a STATUS PDU including a single field that indicates a sequence number (SN) of a first PDU the UE received but unsuccessfully decoded within the receive window. Alternatively, the UE may transmit STATUS PDU segments based on which PDUs the UE receives and the quantity resources in the uplink grant. In some cases, the UE may transmit a STATUS PDU that includes a first field to indicate an SN of a first PDU the UE received but unsuccessfully decoded within the receive window, and one or more offset fields that indicate SNs of respective PDUs subsequent to the first PDU.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive information indicating a reservation or allocation of a resource for transmission of a first signal by another network node, wherein the information identifies whether the network node is to use the resource for transmission of a second signal concurrently with the first signal. The network node may transmit the second signal in the resource based at least in part on the information identifying whether the network node is to use the resource for transmission of the second signal. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described technique provide for a user equipment (UE) to selectively transmit an uplink repetition configured with intra-slot frequency hopping during a slot including both sub-band full duplex (SBFD) and non-SBFD symbols. For example, the UE may receive a control message scheduling repetitions of an uplink message and indicating a configuration for intra-slot frequency hopping for the repetitions. In some cases, the UE may selectively transmit a repetition during a mixed symbol slot according to whether the slot is considered available, an alignment of a boundary between the SBFD symbols and non-SBFD symbols of the mixed symbol slot with time resources for portions of the repetition, transmission parameters associated with SBFD symbols and non-SBFD symbols, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, capability information indicating a set of uplink transmission capabilities. The UE may transmit, to the network node, an indication of a power class switch from a first power class associated with a first uplink transmission power to a second power class associated with a second uplink transmission power. The UE may transmit, to the network node, an indication of a power class switching mode associated with the power class switch. The UE may transmit, to the network node, an uplink transmission based at least in part on one or more revised uplink transmission capabilities, from the set of uplink transmission capabilities, associated with the power class switching mode. 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 receive, from a network, a time domain resource allocation associated with a physical channel that is mapped only to symbols associated with a full-duplex mode or only to symbols associated with a non-full-duplex mode in a slot. Alternatively, the UE may receive, from the network, a time domain resource allocation associated with a physical channel that is mapped only to symbols associated with a full-duplex mode or only to symbols associated with a non-full-duplex mode in a slot. The UE may further communicate with the network using the physical channel. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.
