Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radar enabled device may perform a plurality of listen before talk (LBT) procedures corresponding to a plurality of chirp lengths. The radar enabled device may transmit a particular signal (e.g., a radar signal) based at least in part on a successful result of an LBT procedure of the plurality of LBT procedures. Numerous other aspects are provided.
Claims30
A method performed by a radar enabled device, comprising:
- performing a plurality of listen before talk (LBT) procedures corresponding to a plurality of chirp lengths and a plurality of LBT frames, wherein the plurality of LBT frames include time frames corresponding to the plurality of chirp lengths;
- and
- transmitting a radar signal, at a first LBT boundary of a first pair of LBT boundaries associated with a first LBT frame of the plurality of LBT frames, based at least in part on a successful result of a first LBT procedure of the plurality of LBT procedures, wherein the first LBT frame is associated with a first chirp length of the plurality of chirp lengths.
A radar enabled device, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- perform a plurality of listen before talk (LBT) procedures corresponding to a plurality of chirp lengths and a plurality of LBT frames, wherein the plurality of LBT frames include time frames corresponding to the plurality of chirp lengths;
- and
- transmit a radar signal, at a first LBT boundary of a first pair of LBT boundaries associated with a first LBT frame of the plurality of LBT frames, based at least in part on a successful result of a first LBT procedure of the plurality of LBT procedures, wherein the first LBT frame is associated with a first chirp length of the plurality of chirp lengths.
A non-transitory computer-readable medium storing a set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a radar enabled device, cause the radar enabled device to:
- perform a plurality of listen before talk (LBT) procedures corresponding to a plurality of chirp lengths and a plurality of LBT frames, wherein the plurality of LBT frames include time frames corresponding to the plurality of chirp lengths;
- and
- transmit a radar signal, at a first LBT boundary of a first pair of LBT boundaries associated with a first LBT frame of the plurality of LBT frames, based at least in part on a successful result of a first LBT procedure of the plurality of LBT procedures, wherein the first LBT frame is associated with a first chirp length of the plurality of chirp lengths.
An apparatus for a radar enabled device, comprising:
- means for performing a plurality of listen before talk (LBT) procedures corresponding to a plurality of chirp lengths and a plurality of LBT frames, wherein the plurality of LBT frames includes time frames corresponding to the plurality of chirp lengths;
- and
- means for transmitting a radar signal, at a first LBT boundary of a first pair of LBT boundaries associated with a first LBT frame of the plurality of LBT frames, based at least in part on a successful result of a first LBT procedure of the plurality of LBT procedures, wherein the first LBT frame is associated with a first chirp length of the plurality of chirp lengths.
