Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a configuration message that indicates first paging monitoring occasions (MOs) for first consecutive synchronization signal blocks (SSBs) to be transmitted in a first set of beams and second paging MOs for second consecutive SSBs to be transmitted in a second set of beams. The UE may monitor for the first consecutive SSBs during the first paging MOs and for the second consecutive SSBs during the second paging MOs such that the first paging MOs overlap in time with the second paging MOs. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving, from a base station on a first subband of an unlicensed frequency band, control information that includes a resource allocation of an uplink transmission associated with the first UE and a demodulation reference signal (DMRS) configuration of a downlink transmission associated with a second UE. The apparatus also may obtain one or more measurements of a DMRS within channel activity on a second subband of the unlicensed frequency band using a listen-before-talk (LBT) operation based on the DMRS configuration. The apparatus also may determine whether the channel activity corresponds to the downlink transmission associated with the second UE based on the one or more measurements of the DMRS within the channel activity. The apparatus also may communicate, with the base station on the second subband, the uplink transmission when the channel activity corresponds to the downlink transmission associated with the second UE.

Abstract: Methods, systems, and devices for wireless communications are described which provide for efficient backhaul communications and identification of resources for cross-link interference (CLI) measurements and reporting. A common resource pool may be configured in which CLI measurements for resources within the resource pool have a common configuration. When providing information indicating resources that are to be measured for CLI, a bitmap that indicates resources within the common resource pool may be provided with CLI measurement configurations corresponding to the common resource pool configuration. Such a bitmap may be communicated via backhaul connections between neighboring base stations when initiating a CLI measurement. Various described techniques also provide for common configuration for CLI measurements, provide for efficient reporting of CLI measurements, and provide for accurate representation of CLI based on measurements at a victim UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a full-duplex user equipment (UE) may identify timing for performing an interference measurement based at least in part on a scheduled uplink transmission time. The full-duplex UE may perform, in a particular symbol and in accordance with the timing for performing the interference measurement, a self-interference measurement and a cross-link interference measurement. Numerous other aspects are provided.

Abstract: Aspects relate to dynamically changing the slot format of a slot between half-duplex and sub-band full-duplex and/or to changing flexible symbols within a flexible slot between half-duplex and sub-band full-duplex when a base station is configured to operate in a sub-band full-duplex mode. A slot format indicator (SFI) indicating the slot format of the slot may be signaled, for example, via downlink control information (DCI) mapped to a downlink control channel or medium access control (MAC) control element (MAC-CE) mapped to a downlink data channel. To improve reliability, various SFI boosting mechanisms may further be employed. For example, the base station may apply a higher aggregation level to the SFI, transmit repetitions of the SFI across multiple beams, apply a CRC enhancement and/or MCS enhancement to the downlink control channel carrying the SFI, and/or apply a power boost to the SFI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may adjust a transmission parameter, associated with an uplink transmission from the UE, such that a phase for the uplink transmission is continuous across symbols of the uplink transmission. Adjusting the transmission parameter includes at least one of: rate-matching, puncturing, or power scaling one or more of the symbols within the uplink transmission, modifying at least one of a modulation and coding scheme or a power associated with a downlink transmission to the UE, or a combination thereof. The UE may further transmit, to a base station, the uplink transmission based at least in part on adjusting the transmission parameter. Numerous other aspects are provided.
