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 base station may transmit configuration signaling such as radio resource control (RRC) signaling to a user equipment (UE) which indicates a number of sounding reference signal (SRS) resource sets and respective SRS resources within each of the SRS resource sets that may be used for channel estimation. The base station may subsequently transmit a control message such as a medium access control (MAC) control element (CE) to the UE, which indicates an activation status for at least one SRS resource within the SRS resource set. Basedon the indicated activation status for the at least one SRS resource, the UE may transmit one or more SRSs to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a configuration for performing channel sensing. The configuration may include one or more parameters corresponding to a processing time associated with the channel sensing. The UE may adjust the processing time associated with the channel sensing based on the one or more parameters and a full duplex capability of the first UE. The UE may transmit, using a first set of resources, a sidelink message based on the adjusted processing time. In some examples, the UE may transmit a first data message associated with a first priority level and perform channel sensing for a second data message associated with a second priority level that is higher than the first priority level. The UE may drop the first data message, skip an interference cancellation, or a combination thereof.

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.

Abstract: MAC-CE based dynamic MCS tables switching is introduced to support addition of higher modulation orders and new constellation types. First, a UE receives a RRC configuration indicating a plurality of MCS tables. Next, the UE receives a MAC CE activating a MCS table among the plurality of MCS tables. Doing so allows MCS tables to be dynamically switched via a MAC-CE based activation/reactivation adaptive to current signal to noise (SNR)/spectral efficiency (SPEF) experienced in a downlink and uplink. Finally, the UE communicates data with a base station using a MCS in the activated MCS table.

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 beam failure detection (BED) reference signal set in one or more slots in a full-duplex mode and in one or more slots in a half-duplex mode. The UE may detect beam failure due to self-interference based at least in part on a comparison of measurements of the BFD reference signal set in the full-duplex mode and half-duplex mode. The UE may switch from the full-duplex mode to the half-duplex mode for slots configured for the full-duplex mode based at least in part on detecting beam failure due to self-interference. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to utilizing SRS resources for various types of usages and configuring transmit power on the SRS resources. In an aspect, a user equipment (UE) may determine whether a time gap between a first sounding reference signal (SRS) resource for a first usage and a second SRS resource for a second usage in time is less than a time threshold. Further, the UE may transmit an SRS utilizing one of the first SRS resource or the second SRS resource for both the first usage and the second usage, in response to determining that the time gap is less than the time threshold.

Abstract: A network node may transmit a CSI-RS to a UE. The UE may transmit a CSI report corresponding to at least one UE-selected bandwidth portion of a downlink BWP to the network node based on the CSI-RS. The CSI report may include at least one CQI for the at least one UE-selected bandwidth portion of the downlink BWP. The downlink BWP may be associated with a full-duplex operation.
