Patent ID: 8522107

Claim:
A user equipment comprising: at least one processor configured to implement a radio link control (RLC) sublayer and lower layers including a medium access control (MAC) sublayer and a physical layer; wherein the at least one processor is configured such that the RLC sublayer provides a protocol data unit (PDU) to the lower layers for transmission; wherein the at least one processor is further configured such that the lower layers using a HARQ entity transmit the PDU to a base station; wherein the at least one processor is further configured such that the RLC sublayer, without an indication from an RLC sublayer of a network, provides the PDU in response to an indication from the lower layers for retransmission, wherein the RLC sublayer comprises an acknowledge mode (AM) RLC entity and the providing of the PDU for transmission and retransmission is by the AM RLC entity.
