SYSTEMS AND METHODS FOR TRANSMITTING RADIO LINK CONTROL (RLC) DATA BLOCKS

摘要

In one aspect, the invention provides apparatuses and methods for wirelessly transmitting application data utilizing priority information for each radio link control (RLC) data block transmitted. Advantageously, the application data with a relatively high transmission priority is not substantially delayed by the transmission of application data with substantially lower transmission priorities.

主权项

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:
(a) receiving at the RLC entity a first LLC protocol data units (PDU) formed by the LLC layer and corresponding to a first Packet Flow Context (PFC) and forming a first set of RLC data blocks corresponding to the first LLC PDU; (b) transmitting a subset of the first set of RLC data blocks formed by the RLC entity, wherein each transmitted RLC data block comprises at least a portion of the first LLC PDU, which portion has not previously been transmitted in an RLC data block; (c) after step (a), receiving at the RLC entity a second LLC PDU formed by the LLC layer and corresponding to a second PFC and forming a second set of RLC data blocks corresponding to the second LLC PDU; (d) after step (b), transmitting all of the second set of RLC data blocks formed by the RLC entity, wherein each transmitted RLC data block comprises at least a portion of the second LLC PDU, which portion has not previously been transmitted in an RLC data block; and (e) after step (d), transmitting the remainder of the first set of RLC data blocks formed by the RLC entity but not transmitted in step (b), wherein each transmitted RLC data block comprises at least a portion of the first LLC PDU, which portion has not previously been transmitted in an RLC data block.
