Abstract: A relay device in a mesh wireless access network (WAN) may listen for a signal during a pre-wakeup (PWU) period to determine whether to power on a radio during a wakeup cycle. If the relay device receives a signal during the PWU period, it may power on a radio to transmit a discovery broadcast or to send and receive data. The relay device may also receive synchronization signals during the PWU period to maintain timing synchronization in cases when the wakeup cycle includes long periods of inactivity. That is, different internet of everything (IoE) devices (including relay devices) may operate in different discovery modes based on different mobility patterns. Devices that move frequently may operate in a transient operating mode. Devices that rarely move may operate in a persistent operating mode, and may take advantage of the PWU synchronization signals.

Abstract: An apparatus may receive, from a scheduling entity, sidelink grant information in a downlink control channel. After receiving the grant information in the downlink control channel, the apparatus may transmit a request-to-send (RTS) signal comprising an indication of a requested duration of time to reserve a sidelink channel for sidelink data. If the sidelink channel is available for the requested duration of time, the apparatus may receive a clear-to-send (CTS) signal configured to indicate an availability of the sidelink channel for the requested duration of time. Subsequently, the apparatus may communicate, with another apparatus different from the scheduling entity, the sidelink data using the sidelink channel during the requested duration of time. Afterwards, the apparatus may communicate acknowledgment information corresponding to the communication of the sidelink signal with the other apparatus. Various additional and alternative aspects are described herein.

Abstract: Methods, systems, and devices for wireless communication are described. In an FDD system, a UE may identify an indicator associated with ultra-reliable low latency communications (URLLC) while communicating in a sidelink channel. The UE may also identify dedicated uplink resources in the sidelink channel, and reserve the dedicated uplink resources. The dedicated uplink resources may be reserved for an acknowledgement/negative acknowledgement (ACK/NACK) feedback or for a scheduling request (SR). URLLC data may be communicated, and the reserved uplink resources may be utilized to transmit an ACK/NACK feedback or a SR. In a TDD system, a base station may transmit information identifying dedicated resources for URLLC data. In some cases, a base station may transmit an indicator channel, which a sidelink UE may monitor to determine the presence of URLLC data, and respond accordingly.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus receives configuration information for a sounding reference signal (SRS) transmission with one or more transmission reception points (TRPs), the configuration information assigning a comb value of greater than 4. The apparatus transmits, to the one or more TRPs, the SRS transmission using one of every N resource elements over a span of one or more resource blocks during a slot, where N is greater than 4.

Abstract: Systems and methods are disclosed for efficient signaling between devices. A relay device initiates association with discovery broadcast signals to leaf devices. Each leaf responds with association request signals. After association, the relay periodically sends stay alive signals to the leaf, and the leaf periodically sends link confirmation signals to the relay. If either device fails to send its signal, link breakage is assumed. The leaf device reverts to uplink communication with a base station while searching for another relay. In another embodiment, the leaf foregoes association with a relay, instead forming a device to device (D2D) connection with a relay. A D2D connection is used when the leaf does not expect a link to a relay to be stable enough to justify the association overhead, or when downlink traffic is arriving more frequently than an associated relay is awake. Other aspects, embodiments, and features are also claimed and described.
