Dispatching method for high-speed downlink packet access

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...

Problems solved by technology

[0027] Although the C / I of the UE ranked second in the UE queue is greater than that of the UE ranked third in the UE queue, the total number of information bits N3 transmitted by the third UE through two HS-PDSCH time slots is likely to be greater than N2

[0028] To sum up, the existing C / I scheduling methods do not necessarily achieve the maximum spectrum efficiency
