摘要

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, during a channel occupancy time (COT) associated with one or more resources, via a no listen before talk (no-LBT) channel access mode. The WCD may initiate, after the COT, a reduced COT associated with the one or more resources, wherein the WCD is configured to reduce channel occupancy during the reduced COT. Numerous other aspects are described.

FIG. 11 is a diagram illustrating an example 1100 of transmissions in an unlicensed band, in accordance with various aspects of the present disclosure. As shown in FIG. 11, a first WCD (e.g., base station 110 or UE 120, among other examples) may communicate with a second WCD (e.g., base station 110 or UE 120, among other examples) and a third WCD (e.g., base station 110 or UE 120, among other examples). In some aspects, the first WCD, the second WCD, and the third WCD may be part of a wireless network (e.g., wireless network 100). In some aspects, the first WCD, the second WCD, and the third WCD may communicate via an unlicensed band that does not require channel sensing before beginning a transmission. In some aspects, the wireless network may include an unlicensed band in a sub 7 GHz band and/or one or more millimeter wave bands.

The first WCD may communicate with the second WCD during a COT 1105 for a first set of beams. In some aspects, the first WCD may transmit one or more communications to the second WCD during the COT 1105. In some aspects, the first WCD may receive one or more communications from the second WCD during the COT 1105. In some aspects, a duration may be determined based at least in part on an amount of time of communication by the first WCD, using the first set of beams, without a gap. In some aspects, a duration may be determined based at least in part on an amount of time of communication by the first WCD, using the first set of beams, without a gap that satisfies a gap duration threshold. For example, a duration of the COT 1105 may be determined based at least in part on an interval that includes multiple transmissions to the second WCD or from the second WCD using the first set of beams.
