Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a victim user equipment (UE) may measure a cross-link interference strength from an aggressor UE based at least in part on an uplink transmission from the aggressor UE colliding with a downlink transmission to the victim UE. The victim UE may transmit cross-link interference information to the aggressor UE on a sidelink channel. For example, the cross-link interference information transmitted to the aggressor UE may indicate at least the cross-link interference strength measured by the victim UE. Numerous other aspects are provided.

Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.

Abstract: The present disclosure relates to methods and devices for wireless communication at a wireless device of a wireless wearable device. In one aspect, the wireless device may transmit a first report based on one of a location of the wireless wearable device, a time period, or reception of a user-controlled indication to transmit the first report. The wireless device may also receive, based on the transmitted first report, a configuration to switch from a first mode to a second mode. In some aspects, the configuration can include at least one parameter associated with a power savings at the wireless wearable device while in the second mode. Additionally, the wireless device can operate based on the at least one parameter while in the second mode.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may transmit configuration information indicating a first precoding matrix indicator (PMI) parameter and a second PMI parameter, wherein the first PMI parameter is associated with non-simultaneous activity of a distributed unit (DU) and a mobile termination (MT), and wherein the second PMI parameter is associated with simultaneous activity of the DU and the MT. The wireless node may perform a communication in accordance with a selected PMI parameter of the first PMI parameter and the second PMI parameter based at least in part on whether the DU and the MT are simultaneously active. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for supporting multiple types of random access occasions. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), an indication of at least two types of random access occasions (ROs) including a first RO type and a second RO type for communicating in a first coverage area of the BS as part of a random access process for the UE to establish a connection with the BS in the first coverage area. The method further includes transmitting, to the BS, a preamble on an RO of one of the first RO type or the second RO type, wherein a preamble format of the preamble is based on whether the RO is of the first RO type or the second RO type.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for an uplink control channel, wherein the configuration information includes at least one of: a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone. The UE may transmit uplink control information (UCI) on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information. Numerous other aspects are provided.
