Method and device for frame acknowledgment

Abstract

A method for frame acknowledgement, comprising caching the unacknowledged frame; determining whether a caching capacity threshold is reached; bearing an immediate acknowledgement instruction into a data frame, and sending the data frame the caching capacity threshold is reached; wherein, the immediate acknowledgement instruction is for use in instructing a return acknowledge response of all unacknowledged frames in a specified physical frame period.

What is claimed is: 
     
         1 . A method for frame acknowledgement, comprising:
 caching the unacknowledged frame;   determining whether a caching capacity threshold is reached;   bearing an immediate acknowledgement instruction into a data frame, and sending the data frame the caching capacity threshold is reached;   wherein, the immediate acknowledgement instruction is for use in instructing a return acknowledge response of all unacknowledged frames in a specified physical frame period.   
     
     
         2 . The method of  claim 1 , wherein, bearing the immediate acknowledgement instruction into the frame header of data frame. 
     
     
         3 . The method of  claim 1 , wherein, transmitting said data frame having the immediate acknowledgement instruction attached thereto in the downlink physical period of this frame; and
 the immediate acknowledgement instruction is for use in instructing a return frame acknowledge response in the uplink physical period of this frame.   
     
     
         4 . The method of  claim 1 , wherein, transmitting the data frame having the immediate acknowledgement instruction attached thereto in the uplink physical period of this frame; and
 the immediate acknowledgement instruction is for use in instructing a return frame acknowledge response in the downlink physical period of next frame.   
     
     
         5 . A device for frame acknowledgement, comprising:
 caching module, configured to cache an unacknowledged frame;   judging module, configured to judge whether a caching capacity threshold is reached;   encapsulation module, configured to bear instant acknowledgement indication in data frame when caching capacity threshold is reached, wherein the instant acknowledgement indication is used to indicate a return acknowledge response of all unacknowledged frames in a specified physical frame period; and   sending module, configured to deliver the data frame of the instant acknowledgement indication out.   
     
     
         6 . The device of  claim 5 , wherein, the encapsulation module bears the instant acknowledgement indication in the frame header of data frame. 
     
     
         7 . The device of  claim 5 , wherein, the sending module sends the data frame which carries the instant acknowledgement indication in the down physical period of this frame; and
 the instant acknowledgement indication indicates the up physical period returned frame acknowledgement of this frame.   
     
     
         8 . The device of  claim 5 , wherein, the sending module sends the data frame which carries the instant acknowledgement indication in the up physical period of this frame; and
 the instant acknowledgement indication indicates the down physical period returned frame acknowledgement of next frame.
