Methods and devices for facilitating data retransmissions in wireless communication systems

A method operational on a wireless communications device, comprising:

• transmitting a plurality of data blocks;
• initiating a block timer associated with a round trip time for each data block of the plurality of data blocks;
• receiving a transmission including an indication that at least one data block of the plurality of data blocks has not been successfully received, wherein the transmission is received prior to expiration of the block timer;
• and
• retransmitting the at least one data block.

An access terminal, comprising:

• means for transmitting a plurality of data blocks;
• means for initiating a block timer associated with a round trip time for each data block of the plurality of data blocks;
• means for receiving a transmission including an indication that at least one data block of the plurality of data blocks has not been successfully received, wherein the transmission is received prior to expiration of the block timer;
• and
• means for retransmitting the at least one data block.

A computer-readable storage medium, comprising programming for causing a computer to:

• transmit a plurality of data blocks;
• initiate a block timer associated with a round trip time for each data block of the plurality of data blocks;
• receive a transmission including an indication that at least one data block of the plurality of data blocks has not been successfully received, wherein the transmission is received prior to expiration of the block timer;
• and
• retransmit the at least one data block.
