Scheduling method, scheduler and network access device

Abstract

The embodiment of the invention discloses a scheduling method. The method comprises the following steps: when it is determined that received decoding information of user equipment (UE) is decoding failure indication, obtaining decoding failure indication frequency and uplink channel quality of the UE; and when it is determined that the decoding failure indication frequency is not larger than a first threshold and / or the uplink channel quality is not smaller than a second threshold, triggering data retransmission. The embodiment of the invention further discloses a scheduler and a network access device.

Description

technical field [0001] The invention relates to resource scheduling management technology in the communication field, in particular to a scheduling method, a scheduler and network access equipment. Background technique [0002] In the 3rd Generation Partnership Project (3GPP, The 3rd Generation Partnership Project) agreement, the High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) network adopts the hybrid automatic retransmission (HARQ, HYBRID AUTOMATIC REPEAT REQUEST) technology to achieve fast data Retransmission; after receiving the data sent by the radio network controller (RNC, Radio Network Controller), the base station (Node B) selects the high-speed shared control channel (HS-SCCH, High Speed ​​Shared Control Channel) and high-speed downlink through the HSDPA scheduler Share physical channel (HS-PDSCH, High-Speed ​​Physical Downlink Shared Channel) and other scheduling resources, and send data to user equipment (UE, User Equipment) in tu...

Problems solved by technology

[0004] In the prior art, due to factors such as the poor quality of the uplink channel, when the uplink decoding module decodes the HS-DPCCH information, there will be decoding failures or errors. At this time, the uplink decoding module will feed back the DTX information to the HSDPA scheduler. The DTX information may be wrong decoding information of the UE; for example, if the information fed back by the UE through the HS-DPCCH is ACK information, but due to factors such as poor uplink channel quality, the uplink decoding module is decoding the HS-DPCCH information error or decoding failure, which will cause the uplink decoding module to feed back DTX information to the HSDPA scheduler, so that the HSDPA scheduler triggers HARQ data retransmission

[0005] In the prior art, when the uplink channel quality is poor and the uplink and downlink are unbalanced, the uplink decoding module feeds back wrong UE decoding information to the HSDPA scheduler multiple times, resulting in an incorrect HSDPA retransmission decision and triggering multiple redundant retransmissions by the HSDPA scheduler This problem consumes a large amount of system scheduling resources, causing the UE rate to drop and affecting user experience
