Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a sensing device may transmit a first Layer 2 (L2) data packet that includes a Layer 2.5 (L2.5) frame. The sensing device may receive a second L2 data packet that includes a response to the L2.5 frame. Motion data indicating whether an object is moving may be generated based at least in part on a channel frequency response associated with receiving the second L2 data packet. Numerous other aspects are described.
Claims24
A sensing device for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- transmit a first layer 2 (L2) data packet that includes a layer 2.5 (L2.5) frame, wherein the L2.5 frame is transmitted between two or more L2 frames, wherein the two or more L2 frames comprise two or more null frames, and wherein the first L2 data packet is periodically transmitted at a first interval and the two or more L2 frames are periodically transmitted at a second interval;
- and
- receive a second L2 data packet that includes a response to the L2.5 frame, wherein motion data indicating whether an object is moving is generated based at least in part on a channel frequency response (CFR) associated with receiving the second L2 data packet.
A method of wireless communication performed by a sensing device, comprising:
- transmitting a first layer 2 (L2) data packet that includes a layer 2.5 (L2.5) frame, wherein the L2.5 frame is transmitted between two or more L2 frames, wherein the two or more L2 frames comprise two or more null frames, and wherein the first L2 data packet is periodically transmitted at a first interval and the two or more L2 frames are periodically transmitted at a second interval;
- and
- receiving a second L2 data packet that includes a response to the L2.5 frame, wherein motion data indicating whether an object is moving is generated based at least in part on a channel frequency response (CFR) associated with receiving the second L2 data packet.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a sensing device, cause the sensing device to:
- transmit a first layer 2 (L2) data packet that includes a layer 2.5 (L2.5) frame, wherein the L2.5 frame is transmitted between two or more L2 frames, wherein the two or more L2 frames comprise two or more null frames, and wherein the first L2 data packet is periodically transmitted at a first interval and the two or more L2 frames are periodically transmitted at a second interval;
- and
- receive a second L2 data packet that includes a response to the L2.5 frame, wherein motion data indicating whether an object is moving is generated based at least in part on a channel frequency response (CFR) associated with receiving the second L2 data packet.
