Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect an out-of-coverage scenario based at least in part on determining that a synchronization source associated with a wireless network is unavailable or has a signal strength that fails to satisfy a threshold. The UE may transmit, on a sidelink channel, a sidelink synchronization signal in a transmission period that includes a plurality of synchronization signal occasions based at least in part on the out-of-coverage scenario. In some aspects, the UE may transmit the sidelink synchronization signal according to a reduced duty cycle that causes the sidelink synchronization signal to be transmitted during fewer than all of the plurality of synchronization signal occasions. Numerous other aspects are provided.

Abstract: In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

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: Apparatus, methods, and computer-readable media for providing improved power efficiency during DRX wake-up are disclosed. An example method of wireless communication at a UE includes receiving a WUS from a base station while performing a DRX cycle, the WUS indicating data for transmission to the UE. The example method also includes at least one receiving a downlink reference signal or transmitting an uplink reference signal based on the WUS and prior to reception of the data, the uplink reference signal transmitted or the downlink reference signal received during an on-duration of the DRX cycle and in response to receiving the WUS. The example method also includes sending a CSI report to the base station based on the WUS and prior to the receiving of the data. The example method also includes receiving the data following the respective receiving or transmitting of the downlink reference signal or uplink reference signal.

Abstract: Certain aspects of the present disclosure provide techniques for remote interference determination at a first base station based on assistance from one or more neighboring base stations of the first base station. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving from a second BS neighboring the first BS an uplink interference report request. The method further includes transmitting to the second BS an uplink interference report in response to the uplink interference report request, the uplink interference report comprising information indicative of uplink interference caused by one or more user equipments communicating on an uplink with the first BS.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications at a user equipment (UE). The UE may generate a delay status report (DSR) for at least two traffic flows on different logical channels. The at least two traffic flows have a maximum synchronization threshold between each other. The DSR may include at least one remaining delay budget (RDB) parameter related to an RDB of at least one of a first traffic flow or a second traffic flow and the maximum synchronization threshold. The UE may transmit the DSR.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a network entity, a configuration that indicates one of: unevenly spaced cross-link interference (CLI) measurement resources or unevenly spaced CLI measurement windows. The UE may perform a CLI measurement based at least in part on the configuration, wherein the CLI measurement is associated with an uplink data transmission by a second UE. The UE may transmit, to the network entity, an indication of the CLI measurement. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include receiving, from a network node, a first stage downlink control information (DCI) associated with a second stage DCI, where the first stage DCI comprises information regarding a set of time and frequency resources associated with a physical downlink shared channel (PDSCH), and where the second stage DCI includes decoding information associated with the PDSCH. The example method may further include receiving, from the network node based on the information regarding the set of time and frequency resources, a transmission including the second stage DCI and the PDSCH, where the second stage DCI is multiplexed with the PDSCH, and where the second stage DCI is overlapping in time with the PDSCH. The example method may further include decoding the PDSCH based on the second stage DCI.
