Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of Transmission Time Interval changing method that is used to strengthen dedicated channel.
Background technology
The third generation (3G) wireless mobile communications is among the continuous evolution variation, constantly introduce new demand and realize low cost and high-performance, at the 5th edition (R5, Release 5) and sixth version (R6, Release 6) in introduced high speed downlink packet access (HighSpeed Downlink Access respectively, be called for short HSDPA) and high speed uplink packet access (HighSpeed Uplink Packet Access, be called for short HSUPA), its purpose mainly is the overall performance that improves the wireless frequency spectrum utilance and improve system.
HSUPA is the enhancement techniques of WCDMA system to the uplink ability, mainly introduced three kinds of technology: physical layer is mixed automatic repeat requests (Hybrid Automatic RepeatRequest, abbreviation HARQ), the fast dispatch based on base station (Node B), 2 milliseconds of (ms) Transmission Time Interval (Transmission Time Interval, abbreviation TTI) the short frame transmission of (except that specified otherwise, the TTI of this paper all refers to the TTI of E-DCH).The HSUPA systematic function is significantly improved on the transmission performance of uplink service than traditional WCDMA version, the increase of nearly 50%-70% on power system capacity, the minimizing of 20%-55% is arranged, 50% the increase of on the user grouping calling flow, having an appointment in the delay of end-to-end grouping bag.
Use the WCDMA system of HSUPA technology, comprised radio network controller (Radio Network Controller is called for short RNC), Node B and subscriber equipment (UserEquipment is called for short UE).Node B is by measure upstream noise lifting (the Rise over Thermal of each sub-district in good time, be called for short RoT), UE is (except that specified otherwise, the all UE that mentions of this paper are meant the UE that has disposed the HSUPA business) uplink signal-channel quality, by strengthening dedicated channel (Enhanced Dedicated Channel, abbreviation E-DCH) upstream data obtains the dispatch request information of UE, RoT situation according to the sub-district, the uplink signal-channel quality of UE, the dispatch request information of UE, the priority of UE, information such as scheduling strategy that Node B scheduler adopts and algorithm determine to distribute to the scheduling authorization of each UE, send corresponding dispatching command then to corresponding UE; UE is according to scheduling authorization and the non-scheduling authorization of RNC configuration and the buffer state of UE of Node B, in the pre-configured enhancing dedicated channel transport format combination of RNC (E-DCH Transport FormatCombination is called for short E-TFC) table, select suitable transformat merging to send up E-DCH data to Node B to UE.
Node B according to decode results, returns ACK or nack message in the specific time to UE after receiving the up E-DCH data that UE sends.
When the TTI switching takes place, if switch to 2ms TTI from 10ms TTI, corresponding E-DCHHARQ indicating channel (the E-DCH Hybrid ARQ Indicator Channel of two the HARQ processes (HARQ Process) before and after the switching instant then, abbreviation E-HICH) time overlaps (as shown in Figure 1), agreement is not stipulated this what state processing, cause Node B and UE can not guarantee to accomplish consistent, cause the data transmission exception when switching.
Summary of the invention
One or more problems in view of the above the present invention proposes a kind of Transmission Time Interval changing method that is used to strengthen dedicated channel, and the processing method of E-HICH when switching by clearly being defined in TTI accomplishes that Node B and the consistent of UE handle.
The Transmission Time Interval changing method that is used to strengthen dedicated channel according to an embodiment of the invention may further comprise the steps: step S202, support between radio network controller foundation and the Node B strengthens the Radio Link of dedicated channel, and Node B strengthens dedicated channel communications normally according to the configuration of radio network controller; Step S204, radio network controller sends the radio link reconfiguration order reconfiguring the information that strengthens dedicated channel to Node B, and switches the current transmission time interval that strengthens dedicated channel; Step S206, Node B is carried out reconfiguration process according to the radio link reconfiguration order, sends the information of the enhancing dedicated channel after reshuffling.
Wherein, the radio link reconfiguration order comprises the entry-into-force time, and in step S206, when the entry-into-force time arrived, Node B sent the information of the enhancing dedicated channel after reshuffling.Node B is still under the situation of the information of the enhancing dedicated channel before transmission is reshuffled when the entry-into-force time arrives, and stops to send the information of the enhancing dedicated channel before reshuffling and only sends the information of the enhancing dedicated channel after reshuffling.
Wherein, the Transmission Time Interval changing method is used for the Transmission Time Interval of 10ms is switched to 2ms.
By the present invention, solved the uncertainty of TTI E-HICH when 10ms switches to 2ms, and reduced the retransmission rate when 10ms switches to 2ms at TTI.
