Abstract: A user equipment (UE) and base station may be configured to implementing trigger-based joint TX-RX sensing for channel access. In some aspects, the UE may monitor, via a receiver, for one or more transmissions from a first base station, detect, during the monitoring, interference associated with a pre-grant communication, the pre-grant communication associated with a future communication between a second base station a second user equipment, and transmit, via a transmitter, a reservation communication to the second base station in response to the pre-grant communication. In some aspects, the UE may receive the one or more communications from the first base station, without interference from the second base station, based on transmitting the reservation communication.

Abstract: Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that different symbol durations coexist.

Abstract: A method of wireless communication includes determining, by a communication device, a value of a counter associated with a listen-before-talk (LBT) operation. The method further includes, after determining the value of the counter and during a first portion of a deferral interval associated with the LBT operation, performing a first measurement of a particular duration to determine a first energy value. The method further includes, during a second portion of the deferral interval subsequent to the first portion, performing a second measurement of the particular duration to determine a second energy value. The method also includes determining whether to initiate a contention interval associated with the LBT operation based on the first energy value and further based on the second energy value.
