Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first indication of a first cell associated with a first uplink carrier and a first downlink carrier and a second cell associated with a second uplink carrier, wherein the second cell comprises an uplink-only cell. The UE may receive, via the first downlink carrier of the first cell or via the second downlink carrier associated with a third cell, a second indication of subsequent communications to be performed via the first uplink carrier of the first cell, the second uplink carrier of the second cell, or both. The UE may perform the subsequent communications according to the second indication, wherein the subsequent communications comprise at least one of access communications, uplink communications, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may transmit a first sidelink reference signal (SL-RS) to a second network node. The first network node may receive, from the second network node, a second SL-RS and channel state information (CSI) that is associated with the first (SL-RS). The first network node may determine a (CSI)-related parameter based on the second (SL-RS) and the (CSI). The first network node may transmit, to the second network node, the (CSI)-related parameter or a communication based on the (CSI)-related parameter. 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 a configuration for sidelink discontinuous reception (DRX) that indicates a DRX on duration. The UE may selectively perform sensing for sidelink resource selection outside of the DRX on duration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, the described techniques provide for identifying interference signals on multiple layers or resources and determining whether the interference signals transmitted on a particular layer or resource were precoded using linear precoding (LP) or NLP. In this aspect, a receiving device may equalize signals received from a transmitting device (e.g., filter out interference signals) based on determining whether the interference signals were precoded using a first type of precoding (e.g., linear precoding (LP)) or a second type of precoding (e.g., NLP). In another aspect, the described techniques provide for performing interference measurements on signals precoded using NLP based on categorizing interference resources as being precoded using LP or NLP. In this aspect, a receiving device may perform and report measurements differently for interference signals precoded using LP and interference signals precoded using NLP.

Abstract: Some techniques and apparatuses described herein enable transmission of an uplink control channel in a cross-carrier fashion, where determination of a slot for the transmission is performed based at least in part on a reference component carrier (CC), of a plurality of CCs. For example, the reference CC may be indicated by scheduling information associated with a downlink channel, or may be determined by the UE (e.g., based at least in part on an order associated with the plurality of CCs and availability of a slot for an uplink control channel on the plurality of CCs). In this way, ambiguity with regard to determination of the slot for transmission of the uplink control channel is reduced, thereby providing improved control channel performance, improved resource utilization, and more robust implementation of cross-carrier uplink feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration, for a set of logical channels (LCHs), that indicates at least one restriction, for an LCH in the set of LCHs, the at least one restriction indicating a control resource set group, a search space, or a transmission configuration indicator state. The UE may selectively transmit an uplink communication, using the LCH, according to the at least one restriction. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for association of subband full duplex (SBFD) configurations and bandwidth parts (BWP). An example method, performed at a user equipment (UE), generally includes receiving signaling indicating one or more associations between one or more subband full duplex (SBFD) configurations and one or more bandwidth parts (BWPs), determining whether one of the SBFD configurations is applicable to a first BWP based on the associations, and communicating on the first BWP in accordance with the determination.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may transmit a message indicating that the first device is operating on intermittently available energy harvested from outside the first device. The first device may receive a low-power wakeup signal. The first device may transmit, based at least in part on an energy harvesting state of the first device, an indication that the first device is capable of supporting continuous transmission and reception during a time frame having a configured duration. The first device may communicate during the time frame. Numerous other aspects are described.

Abstract: A configuration to enable a base station to schedule cross carrier scheduling of uplink and/or downlink transmissions using a DCI. The apparatus transmits, to a UE, a PDCCH including a cross carrier schedule. The PDCCH comprises DCI configured to schedule an uplink transmission or a downlink transmission. The DCI includes at least one FDRA field indicating RBs for the uplink transmission or the downlink transmission on at least one serving cell of the cross carrier schedule. The apparatus communicates with the UE based on the cross carrier schedule configured by the DCI.
