Embodiment Construction

[0065] Step S301, receiving a service flow request message sent by the sending end device, the service flow request message carrying the HARQ parameters requested by the sending end device. The service flow request message includes a service flow creation request message—DSA request message and a service flow modification request message—DSC request message. The HARQ parameters at least include one or more of the maximum number of uplink retransmissions, the maximum number of downlink retransmissions and the power offset of the HARQ packet relative to the non-HARQ packet of the service requested by the sending end device. The maximum number of uplink retransmissions, the maximum number of downlink retransmissions, and the power offset of HARQ packets relative to non-HARQ packets are the main parameters in UCD / DCD that can be negotiated separately for different service flows. In the embodiment of the present invention, three TLVs are added in the DSA / DSC message to support the ...

Abstract

The invention discloses a collocation method for hybrid automatic repeat request HARQ parameters, and the method comprises the following steps: service flow request information which is sent by a sender is received, and the service flow request information carries the HARQ parameters which are required by a sender device; and a request response message is sent to the sender device. The embodimentof the invention also provides a collocation system and a device for the HARQ parameters. By the embodiment of the invention, different HARQ parameters are collocated for different service flows, thus making up the defect that the HARQ parameters of different service flows are collocated without distinguishing in the prior art and ensuring better quality of service (QoS).

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, system and device for configuring HARQ parameters. Background technique [0002] High-speed data service is the main feature of 3G, aiming to create a more convenient wireless environment for users' life and work. HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request), an error control technology, is the basic technology of high-speed data transmission. [0003] HARQ technology is a kind of error control technology. The purpose of error control technology is to improve the transmission quality of signals and ensure the reliability of information. In addition to HARQ, there are two main methods: FEC (Forward Error Correction, forward error correction ) and error detection plus ARQ (Automatic RepeatRequest, automatic retransmission). The FEC technology performs error correction according to the redundant information in the received...
