Abstract
Apparatuses, methods, and systems are disclosed for beam switching after LBT procedure. One apparatus includes a processor coupled with at least one memory and configured to cause the apparatus to perform a first listen-before-talk (LBT) procedure using omni-directional sensing to acquire a first channel occupancy time (COT); transmit a first transport block (TB) during the first COT based on a successful result of the first LBT procedure, wherein transmission of the first TB uses a first beam and occupies a first portion of the first COT less than an entirety of the first COT; and perform a second LBT procedure using directional sensing to acquire a remaining portion of the first COT.
Claims20
A user equipment (UE) apparatus comprising:
- a memory;
- and
- a processor coupled with the memory and configured to cause the UE to:
- perform a first listen-before-talk (LBT) procedure using omni-directional sensing to acquire a first channel occupancy time (COT);
- transmit a first transport block (TB) during the first COT based on a successful result of the first LBT procedure, wherein transmission of the first TB uses a first beam and occupies a first portion of the first COT less than an entirety of the first COT;
- and
- perform a second LBT procedure using directional sensing to acquire a remaining portion of the first COT.
A method of a user equipment (UE), the method comprising:
- performing a first listen-before-talk (LBT) procedure using omni-directional sensing to acquire a first channel occupancy time (COT);
- perform a first listen-before-talk (LBT) procedure using omni-directional sensing to acquire a first channel occupancy time (COT);
- transmit a first transport block (TB) during the first COT based on a successful result of the first LBT procedure, wherein transmission of the first TB uses a first beam and occupies a first portion of the first COT less than an entirety of the first COT;
- and
- perform a second LBT procedure using directional sensing to acquire a remaining portion of the first COT.
A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable by one or more processors to:
- perform a first listen-before-talk (LBT) procedure using omni-directional sensing to acquire a first channel occupancy time (COT);
- transmit a first transport block (TB) during the first COT based on a successful result of the first LBT procedure, wherein transmission of the first TB uses a first beam and occupies a first portion of the first COT less than an entirety of the first COT;
- and
- perform a second LBT procedure using directional sensing to acquire a remaining portion of the first COT.
