Abstract
The invention relates to a method for acquiring retransmission interval control information by a node B, which uses an HSDPA under the mode of connection and under the state of a non-cell special channel. The invention comprises the following steps that: a wireless network controller (1) uses an application part signaling of the node B to transmit the retransmission interval control information which is packaged into the application part signaling to the node B through a signaling link; the node B (2) receives and acquires the retransmission interval 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. By adoption of the method, the node B can control retransmission through the acquired information, and the technical problems that an upstream is provided with no feedback channel under the mode of connection and under the state of the non-cell special channel, the node B is ignorant of any feedback information and transmission time interval of retransmission of the node B is controlled are solved.
Description
Technical field
The present invention relates to wireless communication system, be specifically related to a kind of Node B and obtain under connection mode, to use under the non-cell private channel status high-speed downlink grouped data to insert the method for the retransmit interval control information of HSDPA characteristic.
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 blind re-transmission, thereby how the Transmission Time Interval that retransmits to control, and is that " introducing the HSDPA characteristic under connection mode under the non-cell private channel status " used or better be applied to and need a technical problem solving in the reality.
Summary of the invention
The technical issues that need to address of the present invention are the methods how a kind of node B to get retransfer interval control information is provided, and can avoid blind re-transmission in the time of can making Node B introduce the HSDPA characteristic under the non-cell private channel status under connection mode.
Above-mentioned first technical problem of the present invention solves like this, and a kind of method of node B to get retransfer interval control information is provided, and Node B is used HSDPA under the non-cell private channel status under connection mode, it is characterized in that, may further comprise the steps:
1.1) the radio network controller retransmit interval control information of using the node B application part signaling will encapsulate wherein passes to Node B by signaling link; Described application part signalling comprises one or more in Common transport channel foundation, Common transport channel reprovision, audit request, sub-district foundation, cell re-configuration and the Physical Shared Channel reprovision signaling;
1.2) Node B receives and obtain this retransmit interval control information.
According to method provided by the invention, described non-cell private channel status is meant CELL_FACH state and or CELL_PCH state and or URA_PCH state.
According to method provided by the invention, described retransmit interval control information is designated as " at continuous Transmission Time Interval data retransmission ".
According to method provided by the invention, described retransmit interval control information is designated as " designated period mode data retransmission "; Do not retransmit these data in during cycle just, but retransmit this data every one-period ", and provide the periodic quantity of appointment.
According to method provided by the invention, described periodic quantity can be represented with absolute time, also can represent with the number of Transmission Time Interval.
According to method provided by the invention, described retransmit interval control information is designated as " limiting maximum retransmit time mode data retransmission "; Just each the re-transmission with last normally sends these data or the last retransmission time interval that retransmits between these data of transmission can not exceed the maximum retransmit time of qualification ", and provide the maximum retransmit time value of qualification.
According to method provided by the invention, described maximum retransmit time value can be represented with absolute time, also can represent with the number of Transmission Time Interval.
According to method provided by the invention, described retransmit interval control information is designated as " limiting minimum retransmission time mode data retransmission "; Just each the re-transmission with last normally sends these data or the last retransmission time interval that sends between these data of retransmitting can not be less than the minimum retransmission time of qualification ", and provide the minimum retransmission time value of qualification.
According to method provided by the invention, described minimum retransmission time value can be represented with absolute time, also can represent with the number of Transmission Time Interval.
A kind of Node B provided by the invention obtains to use under the non-cell private channel status high-speed downlink grouped data access characteristic data retransmission method of control information at interval under connection mode, radio network controller makes Node B obtain this information by the retransmit interval control information of node B application part signaled data.Thereby have a following tangible technique effect:
Node B can be controlled re-transmission by this information, and under the non-cell private channel status, up without any feedback channel, Node B is not known any feedback information under connection mode in solution, the technical problem of the Transmission Time Interval control that Node B retransmits.
