Description

The method and device of dispatch terminal, base station
Technical field
The present invention relates to the communications field, in particular to a kind of method and device of dispatch terminal, base station.
Background technology
High-speed downlink packet access（High Speed Downlink Packet Access, referred to as HSDPA）It is Third generation partner program（The 3rd Generation Parnership Project, referred to as 3GPP）In version 5 （Release-5）A kind of technology of middle proposition, for improving down direction（That is network is to terminal direction）Network data handle up Amount, the cell and single user downlink peak rates of design can reach 14.4Mbps.Then, in order to enable downlink peak rates Higher introduces the access of evolved high-speed packet（High Speed Packet Access Evolution, referred to as HSPA+） New technology, these technologies are included in the 64 phase quadrature amplitude modulation of downlink of Release-7 propositions（Quadrature Amplitude Modulation, referred to as QAM）High order modulation and multiple-input and multiple-output（Multiple-Input Multiple-Output, letter Referred to as MIMO）Antenna technology, the dual carrier HSDPA proposed in Release-8（DC HSDPA）Technology is proposed in Release-9 DC HSDPA+MIMO technologies and Release-10 propose four carrier HSDPAs（Four Carrier HSDPA, referred to as For 4C-HSDPA）Technology.But since HSDPA does not support soft handover, in order to improve experience of the user in cell edge, Release-11 begins one's study for wideband code division multiple access（Wideband Code Division Multiple Access, letter Referred to as WCDMA）The multiple stream transmission technology of HSDPA.The multiple stream transmission technology of HSDPA includes SF-DC Aggregation, DF-4C The configurations such as Aggregation.
Wherein SF-DC Aggregation refer to identical NodeB（Base station）Or HSDPA technologies are used under difference NodeB Two co-frequency cells（Referred to as main serving cell and auxiliary serving cell, wherein main serving cell are also referred to as Serving HS-DSCH Cell, auxiliary serving cell are also referred to as Assisting serving HS-DSCH Cell）In same Transmission Time Interval （Transmission Time Interval, referred to as TTI）Introversive same UE sends different data flows, so as to promote use Data throughout of the family in cell edge.DF-4C refers to identical NodeB（Base station）Or HSDPA technologies are used under difference NodeB Two different frequent points 4 cells（Referred to as main serving cell and auxiliary serving cell, wherein main serving cell are also referred to as Serving HS-DSCH cell, the auxiliary serving cell with frequency are also referred to as Assisting serving HS-DSCH Cell, no Auxiliary serving cell with frequency also becomes Assisting secondary serving HS-DSCH Cell）In same TTI Different data flows is sent to same UE, so as to promote data throughout of the user in cell edge.For ease of description, Auxiliary serving cell in lower application with frequency and different frequencies is all referred to as auxiliary serving cell.
The user that the requirement of HSDPA multi-stream transmission technology starts multiple stream transmission monitors that the high speed of each major-minor serving cell is total to simultaneously Enjoy control channel（High Speed Shared Control Channel, referred to as HS-SCCH）, and up direction to The hybrid automatic repeat-request of each major-minor serving cell feedback combined coding（HARQ）It is indicated with channel quality（Channel Quality Indicator, referred to as CQI）Instruction, the instruction is in High-Speed Dedicated Physical Control Channel（High Speed Dedicated Physical Control Channel, referred to as HS-DPCCH）In sent.Combined coding refer to by The HARQ feedback information of major-minor serving cell is combined latter transmission of coding.
In non-multiple stream transmission system, in order to ensure that base station receives the performance of HS-DPCCH channels, reduce terminal and send HS- The transmission power of DPCCH, 3GPP agreements, which define, allows terminal to repeat to feed back the scheme of HARQ-ACK and CQI, and base station continuously connects Receive the hybrid automatic repeat-request response of multiple repetitions（Hybridautomatic Repeat-request Acknowledgement, referred to as HARQ-ACK）Or can merge after CQI and decode again, can thus improve HARQ-ACK and The decoding performance of CQI.3GPP 25.214 define HARQ-ACK repeat transmission factor for N_acknack_transmit and CQI repeats transmission factor as N_cqi_transmit, while the configuration of N_acknack_transmit and N_cqi_transmit It is independent, value range is all 1~4.
In multiple stream transmission system because activation multithread terminal be all be in it is Zone switched, in the region it is difficult to ensure that Base station receives the performance of HS-DPCCH, particularly between station（inter-site）Under scene, the transmission of HS-DPCCH is with uplink Road is sent on the basis of best base station, and the performance that the poor base station of another uplink receives HS-DPCCH hardly results in Ensure.At present, 3GPP RAN1 have agreed to the range of extension HS-DPCCH transmission powers to solve the problems, such as this, but the method This cannot be thoroughly solved the problems, such as under any circumstance, such as under terminal transmission power limited situation, without extra transmitting work( It can not just be solved when rate distributes to HS-DPCCH by increasing the method for transmission power.For this purpose, 3GPP RAN1 propose to use again Terminal is allowed to repeat to feed back the scheme of HARQ-ACK and CQI during similar non-multistream system.This scheme can improve base station and receive HS- The performance of DPCCH, while reduce the power of terminal transmission HS-DPCCH.But it is realized in multiple stream transmission system using existing protocol Feedback HARQ-ACK and CQI is repeated, it can be because of each cell（Or base station）The repeat factor parameter of configuration is different and dispatches It is inconsistent and cause base station merge HARQ-ACK and/or CQI when there is decoding error.
