Embodiment Construction
[0048] For single-carrier uplink packet data transmission, the channel resources of the cell are time slots and code channels. For multi-carrier uplink packet data transmission, if we only support the resource allocation scheme that all the channels used for high-speed uplink packet data transmission of a user can only be allocated on the same carrier, it will limit the flexibility of resources and will also limit data transfer rate. To this end, this embodiment provides a method for establishing a channel for multi-carrier high-speed uplink packet data transmission.
[0049] figure 1 It is a flowchart of a method for establishing a multi-carrier high-speed uplink packet data transmission service channel provided by the present invention. The following combination figure 1 , which specifically illustrates the channel establishment method for multi-carrier high-speed uplink packet data transmission provided by the present invention. The specific steps of the method are:

The invention discloses a channel building method of multicarrier high speed up-running grouped data transmission, comprising: first, determining the channel resource number of high speed up-running grouped data transmission required by the district; then selecting N carriers to constitute the high speed up-running grouped data transmission carrier resource of the district from M carriers of the district; dividing the channel resource provided by the high speed up-running grouped data transmission carrier resource of the district into two groups of scheduling transmission resource and non-scheduling transmission resource; when UE initiates high speed up-running grouped data transmission operation request, the network side distributes resource required by the non-scheduling transmission and scheduling transmission according to capacity level of the terminal, thereby building transmission and control channels. The invention effectively solves the problems of building the channels under the multicarrier for the high speed up-running grouped data transmission operation. Meanwhile, the invention also discloses corresponding transmitting method and a wireless network controller used formulticarrier high speed up-running grouped data transmission.
Description
technical field [0001] The invention relates to a wireless data transmission technology in the field of mobile communication, in particular to a channel establishment method of a multi-carrier high-speed uplink packet data transmission service, a data transmission method and a network controller thereof. Background technique [0002] In order to improve the uplink data transmission capability, frequency division duplex (FDD, Frequency Division Duplex) mode and time division duplex (HCR TDD, High ChipRate Time Division Duplex) mode in wideband code division multiple access system (WCDMA), as well as time division synchronization Code division multiple access system (TD-SCDMA, also known as low chip rate TDD mode, LCR TDD) successively introduced enhanced uplink (EnhancedUplink) technology in Release6 and Release7 defined by the third generation mobile communication standardization organization, called It is HSUPA (High Speed Uplink Packet Access, High Speed Uplink Packet ...
