Abstract
Description
technical field
[0001] The invention relates to a wireless link control technology in a wideband code division multiple access system, in particular to a processing method for high-speed downlink packet access services in an acknowledgment mode. Background technique
[0002] The main functions of RLC (Radio Link Control, wireless link control) in WCDMA (Wide Code Division Multi Access, wideband code division multiple access) are data transmission, flow control, encryption and decryption processing, etc., and the working modes supported by it are TM (Transparent Mode, Transparent Mode), UM (Unacknowledged Mode, Unacknowledged Mode) and AM (Acknowledged Mode, Acknowledged Mode), for AM data transmission, the reliable transmission of data is guaranteed through the sliding window and retransmission mechanism.
[0003] RLC retransmission is a mechanism defined in the AM mode to ensure the reliability and correctness of data transmission.
[0004] After the RLC sends the PDU (Pro...
