Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.

Abstract: A UE determines to send a transmission to a first base station on a first unlicensed frequency channel. The UE determines, for one or more attempts of a listen before talk (LBT) protocol, whether each attempt is a failed attempt or a successful attempt. The UE determines that the first unlicensed frequency channel is one of unavailable based on the LBT protocol failing due to a number of failed attempts exceeding for a first threshold number of failed attempts or a duration of failed attempts exceeding a first threshold duration, or available based on the LBT protocol being successful. The UE sends a report to the first base station indicating whether the first unlicensed frequency channel is unavailable or available through a unicast radio resource control (RRC) message or a medium access control (MAC) control element (CE).

Abstract: Techniques for intra- and inter-operator coordination on a shared communication medium are disclosed. A central coordination server may send an operating mode information message to coordinate operation of different points on the communication medium. An access point may receive such an operating mode information message and adjust one or more communication parameters. An access point may determine a level of timing synchronization with neighboring access points and send a synchronization advertisement message to an access terminal. An access terminal may receive a synchronization advertisement message and perform one or more measurements of the neighboring access points.

Abstract: Techniques for managing re-contention on a shared communication medium are disclosed. In order to facilitate re-contending for access to the communication medium, an access point may adjust one or more uplink transmission parameters associated with a triggering condition for invoking a contention timer. In addition or as an alternative, the access point may mute transmission on the communication medium during one or more symbol periods designated for transmission. In addition or as an alternative, the access point may configure a timing advance to create a re-contention gap.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an open radio access network (O-RAN) distributed unit (O-DU) may generate, at an O-DU application that executes on the O-DU, a first message that does not make use of an O-DU accelerator of the O-DU that is in-line with the O-DU application. The O-DU may transmit, from the O-DU application to an O-RAN radio unit (O-RU), the first message via a passthrough of the O-DU accelerator, wherein the first message does not make use of the O-DU accelerator based at least in part on a payload of the first message being transferred unchanged by the O-DU accelerator to the O-RU. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for prioritized signaling via a functional application programming interface (FAPI). A method for conveying uplink (UL) payload may include receiving, at a physical (PHY) layer, a UL payload from one or more user equipments (UEs) and delivering different segments associated with the UL payload, to a medium access control (MAC) layer, in different messages via a functional application platform interface (FAPI). According to certain aspects, the different segments may carry UL payload with different priorities, and segments with higher priority UL payload may be delivered, to the MAC layer, prior to segments with lower priority UL payload.
