  • Patent number: 11432325
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may determine a configuration for UE-to-UE sharing of a channel occupancy time (COT) and may transmit the configuration to a UE to indicate that it can share a UE-acquired COT with at least another UE. A UE may acquire a COT using a listen-before-talk (LBT) procedure, and if successful, may transmit a signal indicating that the COT is being shared with at least another UE. Additionally, a UE may receive a signal from another UE indicating that it has acquired a COT in a shared spectrum and that the COT is being shared with other UEs. The UE may perform a shortened LBT procedure within the COT, and if successful, may transmit an uplink transmission in the shared spectrum.

    Abstract: A method for a first network device involves transmitting, to one or more second network devices, an uplink message that includes an indication of a receive window time interval, and may also include an indication of a request for a downlink message. The method also involves initiating a scheduled receive mode that causes the first network device to transition the first network device to a first power state, and perform a receive window procedure after the receive window time interval has elapsed. The receive window procedure includes transitioning the first network device to a second power state and listening for the downlink message for a duration of time. The method further involves determining that an expiration condition has been met while the first network device is in the scheduled receive mode.
