Determination of Feedback Timing

Abstract

Embodiments of the present disclosure relate to a method and device for determining feedback timing. In example embodiments, the first communication device obtains information indicating at least one of a capability, a timing requirement, and a service type of a second communication device. Based on the obtained information, the first communication device determines feedback timing to be used by the second communication device. Then, the first communication device sends an indication of the feedback timing to the second communication device for communication with the second communication device in accordance with the feedback timing.

What is claimed is: 
     
         1 . A method implemented in a first communication device, comprising:
 obtaining information indicating at least one of a capability, a timing requirement, and a service type of a second communication device;   determining, based on the obtained information, feedback timing to be used by the second communication device; and   sending an indication of the feedback timing to the second communication device for communication with the second communication device in accordance with the feedback timing.   
     
     
         2 . The method of  claim 1 , wherein determining the feedback timing comprises: selecting a frame structure including the feedback timing. 
     
     
         3 . The method of  claim 2 , wherein sending the indication of the feedback timing comprises:
 sending an indication of the frame structure to the second communication device.   
     
     
         4 . The method of  claim 1 , wherein determining the feedback timing comprises:
 selecting the feedback timing based on an association between the feedback timing and the capability, the timing requirement or the service type of the second communication device.   
     
     
         5 . The method of any of  claim 1 , wherein obtaining the information comprises:
 receiving, from the second communication device, information about a processing time of the second communication device indicating the capability of the second communication device.   
     
     
         6 . The method of  claim 5 , wherein receiving the information about the processing time comprises:
 receiving, from the second communication device, the information about the processing time of the second communication device in a communication configuration.   
     
     
         7 . The method of  claim 1 , wherein obtaining the information comprises:
 receiving, from the second communication device, the information indicating the timing requirement of the second communication device associated with a communication configuration.   
     
     
         8 . The method of any of  claim 1 , wherein determining the feedback timing comprises:
 obtaining a propagation time of data associated with the second communication device; and   determining the feedback timing further based on the obtained propagation time.   
     
     
         9 . A communication device, comprising:
 a first obtaining unit configured to obtain information indicating at least one of a capability, a timing requirement, and a service type of a further communication device;   a first determining unit configured to determine, based on the obtained information, feedback timing to be used by the further communication device; and   a first sending unit configured to send an indication of the feedback timing to the further communication device for communication with the further communication device in accordance with the feedback timing.   
     
     
         10 . The communication device of  claim 9 , wherein the first determining unit is further configured to select a frame structure including the feedback timing. 
     
     
         11 . The communication device of  claim 10 , wherein the first sending unit is further configured to send an indication of the frame structure to the further communication device. 
     
     
         12 . The communication device of  claim 9 , wherein the first determining unit is further configured to select the feedback timing based on an association between the feedback timing and the capability, the timing requirement or the service type of the further communication device.
