System and method for prioritization of retransmission of protocol data units to assist radio-link control retransmission

A MEDIUM ACCESS CONTROL (MAC) ARCHITECTURE REDUCES TRANSMISSION LATENCY FOR DATA BLOCK RETRANSMISSIONS. A PLURALITY OF DATA BLOCKS ARE RECEIVED AND STORED IN A FIRST MEMORY. THE PLURALITY OF DATA BLOCKS ARE THEN TRANSMITTED . A DETERMINATION IS MADE AS TO WHETHER EACH OF THE TRANSMITTED DATA BLOCKS WAS RECEIVED SUCCESFULLY OR NEEDS TO BE RETRANSMITTED BECAUSE THE DATA BLOCK WAS NOT RECEIVED SUCCESFULLY. EACH OF THE TRANSMITTED DATA BLOCKS THAT NEEDS TO BE RETRANSMITTED IS MARKED AND STORED IN A SECOND MEMORY HAVING A HIGHER PRIORITY THAN THE FIRST MEMORY. THE MARKED DATA BLOCKS ARE RETRANSMITTED BEFORE DATA BLOCKS STORED IN THE FIRST MEMORY LOCATION.
