Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station (BS) may detect remote interference, with one or more uplink communications on a physical uplink shared channel (PUSCH) associated with the first BS, caused by propagation of one or more reference signal (RS) communications, transmitted by a second BS, out of a coverage area of the second BS and into a coverage area of the first BS due to reflection of the one or more RS communications. The coverage area of the first BS and the coverage area of the second BS are non-overlapping coverage areas. The first BS may adjust, based at least in part on detecting the remote interference, one or more radio resource allocations of the PUSCH associated with the first BS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.

Abstract: Disclosed are systems and techniques for providing a phase continuity configuration in cross-link interference (CLI) based sensing. For instance, a method for wireless communications at a user equipment (UE) may include receiving, at the UE, a phase reporting configuration from a network entity. The method may include generating, at the UE based on the phase reporting configuration, a phase report comprising one or more phase measurements of a cross-link interference (CLI)-based sensing resource. The method may further include transmitting, to the network entity, the phase report comprising the one or more phase measurements of the CLI-based sensing resource.

Abstract: One general aspect includes a method of wireless communication performed by a user equipment (UE). The method of wireless communication also includes receiving a configuration defining uneven reference signals in a time domain, including defining the uneven reference signals to be received before a paging early indication (PEI) and between the PEI and a paging occasion (PO); exiting a sleeping mode to receive the uneven reference signals before the PEI and between the PEI and the PO, performing a tracking loop adjustment based on the uneven reference signals, decoding a paging message after the tracking loop adjustment, and returning to the sleeping mode. Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information identifying multiple remote UEs for which the UE serves as a relay UE. The UE may receive, from the base station, an indication of a grouping of the remote UEs into one or more paging groups. The UE may monitor, for each paging group of the one or more paging groups, paging occasions associated with that paging group to determine whether paging messages for the remote UEs in that paging group are received from the base station. Numerous other aspects are described.

Abstract: A method of wireless communication at a user equipment (UE) is provided. The method includes receiving, from a scheduling entity, an indication of at least two different cross link interference (CLI) measurement resources of a message for transmission from a transmission source. The method also includes receiving, from an intelligent reflecting surface (IRS), a reflected transmission of the message originating from the transmission source, wherein the reflected transmission of the message is reflected by the IRS based on one or more IRS coefficients. The method further includes determining one or more CLI measurement parameters to generate a report. The method includes transmitting, to the scheduling entity, a CLI measurement report. The method also includes receiving, from the IRS, another reflected transmission of the message originating from the transmission source using one or more configured IRS coefficients that are configured based on the CLI measurement report.

Abstract: A determination of a position of a target mobile device in a wireless communication network employing time-division duplexing (TDD) can use a wireless reference signal from another mobile device with a known position. The other mobile device can be configured to transmit the wireless reference signal using cross-link interference (CLI), where the target mobile device receives the signal during a period in which the target mobile device is configured to receive downlink (DL) communication. The target mobile device then transmits another wireless reference signal, which is received by a base station, which also receives the wireless reference signal from the other mobile device. The timing of these various signals received at the target mobile device and base station can be used to determine the location of the mobile device.
