Abstract
Examples pertaining to latency alignment in device collaborative communications are described. A collaborating communication apparatus obtains information regarding a latency corresponding to a relay operation to relay a radio frequency (RF) signal to a primary communication apparatus or to a network node and provides the information regarding the latency to the primary communication apparatus to facilitate latency alignment in device collaborative communications among the primary communication apparatus, the collaborating communication apparatus and the network node.
Claims19
A method, comprising:
- obtaining, by a processor of a collaborating communication apparatus, information regarding a latency corresponding to a relay operation to relay a radio frequency (RF) signal to a primary communication apparatus or to a network node;
- and
- providing, by the processor, the information regarding the latency to the primary communication apparatus.
A method, comprising:
- obtaining, by a processor of a primary communication apparatus, information regarding an uplink processing delay of a collaborating communication apparatus;
- transmitting, by the processor, a first RF signal on a first time-frequency resource to the collaborating communication apparatus;
- and
- transmitting, by the processor, a second RF signal on a second time-frequency resource to a network node,
- wherein an uplink latency of the transmitting of the second RF signal on the second time-frequency resource with respect to the transmitting of the first RF signal on the first time-frequency resource is determined based on the uplink processing delay.
A method, comprising:
- obtaining, by a processor of a primary communication apparatus, information regarding a downlink processing delay of a collaborating communication apparatus;
- determining, by the processor, a downlink latency based on the downlink processing delay;
- receiving, by the processor, a first RF signal on a first time-frequency resource from a network node, wherein the first RF signal carries baseband data;
- determining, by the processor, a first frame boundary associated with the first RF signal;
- receiving, by the processor, a second RF signal on a second time-frequency resource from the collaborating communication apparatus;
- and
- determining, by the processor, a second frame boundary associated with the second RF signal based on the first frame boundary and the downlink latency.
