Embodiment Construction

[0122] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0123] Before the scheduling method of the present invention is described in detail, the general timing relationship between the HS-SICH carrying CQI and the HS-PDSCH, the CQI information of the HS-SICH, various timing relationships used in the scheduling method, and the timing relationship on the HS-DSCH The data blocks carried, etc. are explained:

[0124] 1. Timing relationship between HS-SICH and HS-PDSCH carrying Channel Quality Indicator (CQI)

[0125] According to the 3GPP standard, the CQI carried on the HS-SICH is generated by the UE according to the latest received scheduled HS-PDSCH. Therefore, the CQI carried on the HS-SICH sent by UE "i" in the "n"th subframe is based on Generated by the scheduled HS-PDSCH of the "m"th subfr...

Abstract

The invention provides a dispatching method for HSDPA (High Speed Downlink Packet Access), which comprises the following steps of: in a current subframe n, dispatching the total quantity I of the priority queues of UEs (User Equipment) according to all the requests in a subdistrict, the maximum quantity NPQ of the priority queues capable of being simultaneously dispatched in the current subframe and the maximum quantity TUE(i) of HSDPA time slots capable of being simultaneously supported by each UE by a dispatcher, determining the priority queues dispatched by the current subframe according to the principle of spectrum efficiency maximization, and allocating high-speed physical downlink shared-channel time-slot resources for each determined priority queue, wherein NPQ=min{I,TPool(n),NHSSCCH}, 1<=NPQ<=5, the TPool(n) is the quantity of the time slots in a high-speed physical downlink shared-channel time-slot resource pool in the subdistrict of the subframe n, the NHSSCCH is the quantity of high-speed shared control channels and high-speed shared information channel pairs in the subdistrict of the subframe n, and the i is the serial number of the UEs; and dispatching the priority queue by utilizing the high-speed physical downlink shared-channel time-slot resource allocated to each determined priority queue. The maximum spectrum efficiency can be obtained through the invention.

Description

technical field [0001] The present invention relates to the dispatching technology in the mobile communication system, in particular to a dispatching method of High Speed ​​Downlink Packet Access (HSDPA). Background technique [0002] In the HSDPA technology of the TD-SCDMA system, there is one HSDPA-specific transmission channel: High Speed-Downlink Shared Channel (HS-DSCH) and three HSDPA-specific physical shared channels: High-speed Shared Control Channel (HS-DSCH) High speed-Shared Control Channel, HS-SCCH), high speed shared information channel (High speed-Shared Information Channel, HS-SICH) and high speed physical downlink shared channel (High speed-Physical Downlink Shared Channel, HS-PDSCH). [0003] The radio network controller (RNC) will configure the HS-PDSCH resource pool of each cell supporting HSDPA. When the RNC configures the HS-PDSCH resource pool of the cell, it will indicate which channel codes of which downlink time slots belong to the resource pool, an...
