Abstract

Aspects of the disclosure provide an apparatus that includes a transceiver circuit and a baseband processing circuit. The transceiver circuit is configured to transmit signals that carry a data unit to another apparatus and receive signals that carry a response from the other apparatus. The baseband processing circuit is configured to provide a first digital stream to carry a data unit to the transceiver circuit for transmission, and provide a second digital stream to carry a portion of the data unit to the transceiver circuit for retransmission when the transceiver circuit receives a response that is indicative of a partial receiving failure of the data unit at the other apparatus.

 the retransmission control circuit is configured to provide the control signals to the transmit processing circuit to generate the second digital stream including the sub data units when the response includes a single negative acknowledgement bit indicative of a receiving failure of the data unit.   
     
     
         4 . The apparatus of  claim 2 , wherein
 the retransmission control circuit is configured to determine the subset of the sub data units when the response includes one or multiple negative acknowledgement bit(s) indicative of specific sub data unit(s) with receiving failure.   
     
     
         5 . The apparatus of  claim 2 , wherein the retransmission control circuit is configured to vary the control signals based on the response to adjust a size of the subset of the sub data units to be included in the second digital stream. 
     
     
         6 . A method for communication, comprising:
 generating, by a first apparatus, a first digital steam to carry a data unit for transmission;   transmitting, wireless signals in response to the first digital stream to carry the data unit to a second apparatus;   receiving, by the first apparatus, wireless signals that carry a response indicative of a partial receiving failure of the data unit from the second apparatus;   generating, by the first apparatus, a second digital stream to carry a portion of the data unit; and   transmitting, wireless signals in response to the second digital stream to carry the portion of the data unit to the second apparatus.   
     
     
         7 . The method of  claim 6 , wherein generating, by the first apparatus, the first digital stream to carry the data unit for transmission further comprises:
 segmenting the data unit to generate sub data units; and   processing the sub data units to generate the first digital stream including symbols for the sub data units.   
     
     
         8 . The method of  claim 7 , wherein generating, by the first apparatus the second digital stream to carry the portion of the data unit further comprises:
 generating the second digital stream including a subset of the sub data units in response to the partial receiving failure.   
     
     
         9 . The method of  claim 8 , wherein generating the second digital stream including a subset of the sub data units in response to the partial receiving failure
 generating the second digital stream including the sub data units when the response includes a single negative acknowledgement bit indicative of a receiving failure of the data unit.   
     
     
         10 . The method of  claim 8 , further comprising:
 determining the subset of the sub data units when the response includes one or multiple negative acknowledgement bit(s) indicative of specific sub data unit(s) with receiving failure.
