Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a central network entity may configure, for a network node, a first configuration indicating one or more transmission windows for inter-network node cross-link interference (CLI) measurement reference signaling. The central network entity may configure, for the network node, a second configuration indicating a plurality of reception windows for inter-network node CLI measurement reference signaling, wherein the one or more transmission windows are configured to be non-overlapped with each reception window of the plurality of reception windows. Numerous other aspects are described.

Abstract: A method of wireless communication performed by a user equipment (UE) includes: receiving a cell configuration associated with a cross-link interference sounding reference signal (CLI-SRS) timing; and transmitting, based on the CLI-SRS timing and a CLI-SRS priority configuration, a first communication at a first time period. A second communication may be scheduled for at least a portion of the first time period, and one of the first communication or the second communication may include a CLI-SRS.

Abstract: Systems and techniques are provided for wireless communications at a network entity. For example, then systems and techniques can include determining, at the network entity, a transmission timing compensation between a first reference signal and a second reference signal. The first reference signal can be transmitted using a first communication link. The second reference signal can be transmitted based on an offset determined based on the transmission timing compensation, wherein the second reference signal is transmitted suing a second communication link. The offset can be used to offset transmission of the second reference signal from transmission of the first reference signal.

Abstract: Systems and techniques are provided for wireless communications performed at a network entity. For example, the systems and techniques can include obtaining, at the network entity, a target relative time difference (RTD). A transmission timing pre-compensation can be determined at the network entity between a first reference signal and a second reference signal, wherein the transmission timing pre-compensation is determined based on the target RTD and one or more network delay components. The first reference signal and the second reference signal can be transmitted using the transmission timing pre-compensation to offset the first reference signal from the second reference signal by the target RTD.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for multi-cell scheduling for power saving. A UE may receive a configuration of one or more first parameters for control channel monitoring based on a first type of scheduling and one or more second parameters for the control channel monitoring based on a second type of scheduling. The UE may monitor for DCI of the first type of scheduling based on a first condition of a scheduling cell and switch from monitoring for the DCI of the first type of scheduling to monitoring for the DCI of the second type of scheduling based on a second condition of a scheduled cell. The UE may receive scheduling information for at least one of a PDSCH or a PUSCH based on the second type of scheduling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may determine at least one of a variable random access response (RAR) window start time, a variable maximum quantity of slots for an index of a first slot of a physical random access channel occasion, or scheduling information related to one or more variable delays for an uplink transmission. The BS may transmit, to a user equipment, at least one of information that identifies the RAR window start time, information that identifies the variable maximum quantity of slots, or the scheduling information. Numerous other aspects are provided.

Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Abstract: Wireless devices can use various super-slot formats to facilitate wireless communication using half duplex (HD) frequency-division duplex (FDD) (HD-FDD). A super-slot has a duration that can span over multiple slots and/or subframes. A super-slot can include uplink symbols and downlink symbols. The super-slot can include a guard period that separates uplink symbols from downlink symbols in the same super-slot. A super-slot can support signal repetition to provide coverage enhancement. Signal repetition can be combined with frequency hopping in a super-slot to provide diversity gain.
