Abstract:
1. A method for dynamic packet retransmissions of a radio link control, hereinafter called RLC, layer for an RLC entity of a transmitter in a wireless communications system, the method comprising: transmitting a first RLC packet, comprising a first header and a first data field, to a receiver; receiving a negative acknowledgment signal corresponding to the first RLC packet from the receiver; receiving a first transport block, hereinafter called TB, size indicated by a protocol layer lower than the RLC layer; constructing a second RLC packet comprising a second header and a second data field filled to the full with partial data of the first data field, wherein the packet size of the second RLC packet depends on the first TB size; transmitting the second RLC packet to the receiver; receiving a second TB size indicated by the protocol layer lower than the RLC layer; constructing a third RLC packet comprising a third header and a third data field comprising data of the first data field that is not included in the second data field, wherein the packet size of the third RLC packet depends on the second TB size; and transmitting the third RLC packet to the receiver; wherein if the third data field is not filled to the full with the data of the first data field that is not included in the second data field, the third data field further comprises a portion of data of a fourth RLC packet that is also negatively acknowledged by the receiver.
