Abstract: Aspects described herein relate to determining and/or scheduling resources for devices in view of cross-channel interference measured between the devices. In an aspect, a first user equipment (UE) can determine a signal measurement of a signal transmitted by a second UE in a first channel, determine, based at least in part on the signal measurement, a cross-channel interference parameter of interference experienced by the first UE, and transmit, to a serving base station that serves the first UE, an indication of the cross-channel interference parameter. In another aspect, a base station can determine a cross-channel interference parameter of interference experienced by a first UE in at least a first channel, based on a signal transmitted by a second UE in a second channel, and can schedule communications for the first UE based at least in part on the cross-channel interference parameter.

Abstract: Apparatus, methods, and computer-readable media for facilitating UE indication of null tone placement for demodulation are disclosed herein. An example method for wireless communication at a UE includes measuring one or more downlink transmissions in one or more frequency subcarriers received from a base station over a time period. The example method also includes transmitting, to the base station, a null tone indication indicating one or more locations for one or more null tones, the one or more locations for the one or more null tones based at least in part on measurements performed on the one or more downlink transmissions received over the time period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, using at least one wake up receiver associated with the UE, one or more wake up signals for beam tracking (WUTs). The UE may measure a quality of each WUT, of the one or more WUTs. The UE may activate a main receiver associated with the UE to perform a beam recovery procedure based at least in part on a measured quality of at least one WUT, of the one or more WUTs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node (e.g., a first user equipment (UE)) may determine a first sidelink discontinuous reception (DRX) priority assigned to the first network node, wherein the sidelink DRX priority is based on one or more criteria associated with the first network node. The first network node may communicate on a sidelink channel using a first set of one or more DRX configurations based on the first sidelink DRX priority assigned to the first network node, wherein the first set of one or more DRX configurations are at least partially aligned in time with a second set of one or more DRX configurations of a second network node (e.g., a second UE) assigned a second sidelink DRX priority that is equivalent to the first sidelink DRX priority. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit a set of reference signals spanning a channel to a user equipment (UE), where each of the reference signals is associated with one of a set of transmit beams. The UE may measure a signal quality of each of the set of reference signals. In some cases, each measured signal quality may correspond to one of a set of subbands of the channel and one of the set of transmit beams. The UE may then transmit an indication of at least one signal quality associated with one of the set of subbands and one of the set of transmit beams. In some cases, the UE may indicate the at least one signal quality according to a configuration that may be indicated by the base station or selected by the UE.

Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of whether an uplink multiple input multiple output (MIMO) communication is to be codebook-based (CB) or non-codebook-based (NCB). The UE may transmit the uplink MIMO communication as CB or NCB based at least in part on the indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicating a first uplink message using a first uplink carrier and a first timing advance (TA) value associated with a first transmission configuration indicator (TCI) state and a second uplink message using a second uplink carrier and a second TA value associated with a second TCI state for the UE. The UE may receive a timing advance group (TAG) configuration which indicates a TA value to apply for a supplementary uplink (SUL) carrier of the serving cell, which is one of the first TA or second TA values. The UE may then transmit a SUL message using the SUL carrier of the serving cell in accordance with the TA value determined for the SUL carrier based on the TAG configuration for the UE.

Abstract: Code block group (CBG) transmission indications for communications configured with multiple transmission time interval (TTI) grants is disclosed. Where multiple TTIs are configured for CBG transmission, the base station may select to signal CBG transmission indications and/or transport block (TB)-level new data indicator (NDI) for each of the configured TTIs along with an index of the TTIs that CBG transmission indicators are sent for. The base station may select to add one or more CBG transmission indications based on the predetermined payload size of the transmission indication signal of the physical downlink control channel (PDCCH).
