Abstract
The invention relates to a retransmission control method corresponding to a HSDPA used under the state of a non-cell special channel, comprising the following steps that: a wireless network controller (1) packages control information corresponding to downstream data of a node B into an application part signaling of the node B, and the control information is transmitted to the node B by a signaling link; the node B (2) receives the control information and performs retransmission or non-retransmission according to the control information, wherein, the application part signaling at least comprises one among establishment signaling of a common transmission channel, reconfiguration signaling of the common transmission channel, audit request signaling, cell establishment signaling, cell reconfiguration signaling and physical shared channel reconfiguration signaling. The method informs the control information corresponding to the downstream data through the application part signaling of the node B, and the technical problem of avoidance of blind retransmission of the node B under the condition that an upstream is provided with no feedback channel under the mode of connection and under the state of the non-cell special channel and the node B is ignorant of any feedback information is solved.
Description
Technical field
The present invention relates to wireless communication system, be specifically related to a kind of high-speed downlink grouped data access characteristic that under connection mode, uses under the non-cell private channel status and carry out the re-transmission controlling method that downlink data transmits correspondence.
Background technology
Two basic manipulation modes of portable terminal are idle pulley and connection mode.Wherein, connection mode can further be divided into four kinds of different states: (one) Universal Mobile Telecommunications System wireless access network registration area paging channel Universal mobile telecommunication system Radio access networkRegister area Paging Channel state, be called for short the URA_PCH state; (2) cell paging channel CELL Paging Channel state is called for short CELL_PCH; (3) cell forward access channel CELLForward Access Channel state is called for short CELL_FACH; (4) cell private channel CELLDedicated Channel state is called for short the CELL_DCH state.These states have further defined the physical channel of portable terminal use and the kind of transmission channel.Non-under the connection mode (four) cell private channel CELL_DCH state is meant other three kinds of states, i.e. CELL_FACH state, CELL_PCH state and URA_PCH state under the connection mode.
In existing system, high-speed downlink grouped data inserts High Speed Downlink PacketAccess, is called for short HSDPA, and its characteristic is only used under the CELL_DCH state.And, also attempt under connection mode, to introduce under the non-cell private channel status HSDPA characteristic in order to improve the performance that the data under the non-cell private channel status send and receive under the connection mode.
In the prior art, under the CELL_DCH state, use the HSDPA characteristic, because the up feedback channel that exists, after so Node B sends downlink data, can be according to up feedback, whether decision retransmits, and the interval of re-transmission depends on and sends downlink data to the retransmission time interval length between the up feedback, and the scheduling of Node B self.
And under connection mode under the non-cell private channel status, because it is up without any feedback channel, Node B is not known any feedback information, be merely able to blindly retransmit, thereby how to send the downlink data re-transmission, be that the technical issues that need to address in the reality are used or better be applied to " introducing the HSDPA characteristic under connection mode under the non-cell private channel status ".
Summary of the invention
The technical issues that need to address of the present invention provide the re-transmission controlling method that a kind of non-cell private channel status uses the HSDPA correspondence, can avoid blindly retransmitting in the time of can making Node B introduce the HSDPA characteristic under the non-cell private channel status under connection mode.
