Abstract:
1. In a wireless communication apparatus comprising a protocol stack comprising a logical link control (LLC) layer and a radio link control (RLC) layer comprising an RLC entity, a method for transmitting RLC data blocks, comprising: receiving, by a transmitting RLC entity, a second LLC packet data unit (PDU) from an LLC layer, after a part of but before the entirety of a first LLC PDU is transmitted as RLC data blocks; comparing, by the transmitting RLC entity, the relative transmission priorities of the first and second LLC PDUs; determining by the transmitting RLC entity whether the second LLC PDU has a higher transmission priority than the first LLC PDU; if so, then transmitting by the RLC entity one or more RLC data blocks corresponding to the second LLC PDU, prior to transmission of any of the remainder of the first LLC PDU, even though the first LLC PDU has not been completely transmitted; and after transmitting the one or more RLC data blocks corresponding to the second LLC PDU, resuming transmission of remaining RLC data blocks corresponding to the first LLC PDU, including any RLC data blocks that were aborted immediately prior to beginning the transmission of the first RLC data block corresponding to the second LLC PDU but not including one or more RLC data blocks corresponding to the first LLC PDU that were transmitted.
