Abstract
The invention discloses a method and a device for transmitting channel quality indicator. The method includes the following steps that: after receiving a data packet of high-speed downlink shared channel (HS-DSCH ) on the downlink, a terminal triggers feedback of an uplink high-speed dedicated physical control channel (HS-DPCCH), the feedback is a physical channel sent by the terminal on enhanced dedicated transmission channel (E-DCH ) resource, the physical channel carrying channel quality indicator (CQI) information and a radio network temporary identifier (E-RNTI); and a node B establishes a correspondence relationship between the E-DCH resource and the terminal, and acquires a CQI of transmitted data to the terminal on the downlink through the correspondence relationship. The invention also discloses a device for transmitting channel quality indicator. By adopting the above method and the device, the feedback of the uplink HS-DPCCH is triggered after the HS-DSCH data are received on the downlink, so transmission delay of the HS-DPCCH is shortened.
Description
Technical field
The present invention relates to the transmission technology of channel quality indication in the wireless communication system, be meant a kind of method and apparatus of transmission channel quality indication especially.
Background technology
(Channel Quality Indicator CQI), is the measurement index of the communication quality of wireless channel to CQI.CQI represents the metric of the channel measurement index of a given channel.Usually, the CQI of a high value representes that a channel has high quality, and vice versa.The CQI of a channel calculates through the serviceability parameter, said performance parameter for example, signal to noise ratio, promptly Signal to Interference plus Noise Ratio or signal compare etc. with noise distortion.These values with other can weigh the CQI that given channel measured value comprehensively can calculate channel.The CQI of a given channel can select to confirm that transmission or modulation scheme provide foundation for communication system.
In communication system; High-speed downlink packet inserts (High Speed Downlink Packet Access; HSDPA) technology can be improved power system capacity; And can significantly promote descending user data rate, can in the bandwidth of one 5 megahertz, the downlink transmission data rate that surpasses 10 MBPSs be provided for Packet data service.Improvement on this performance stems from some key technologies that it adopts, and these technology comprise: Adaptive Modulation and Coding, fast dispatch, advanced receiver design etc.High speed downlink packet access technology has been introduced a new transmission channel; High speed descending sharing channel (High Speed Downlink Shared Channel; The HS-DSCH channel), in order to carry the load of HSDPA, promptly send to the business datum of terminal down link direction.Simultaneously; Can decode to the data on the HS-DSCH in order to ensure the terminal, the HSDPA technology has also been introduced a new physical channel, High-Speed Shared Control Channel (High Speed Shared Control Channel; The HS-SCCH channel), in order to carry the needed information of HS-DSCH demodulation.The last information of HS-SCCH is with the specific sign in terminal; Be HS-DSCH Radio Network Temporary Identifier (HS-DSCH Radio Network Temporary Identifier; The H-RNTI sign) carries out mask, whether send to oneself so that the information on the HS-SCCH that receives can be judged in the terminal.
High-speed uplink packet access technology retransmits the performance that means such as merging are improved system for uplink packet data fast through fast dispatch and physical layer.High-speed uplink packet access technology is introduced a kind of new transmission channel, and enhanced dedicated (Enhanced Dedicated Transport Channel, E-DCH channel) is used for carrying user data, and is single up direction.The physical channel of bearing reinforced dedicated transmission channel is Physical Random Access Channel (Physical Random Access Channel, a PRACH channel).In addition, the physical channel that uplink direction possibly use has: Dedicated Physical Control Channel (Dedicated Physical Control Channel, DPCCH channel) is used to carry the physical layer power control information; High-Speed Dedicated Physical Control Channel (High Speed Dedicated Physical Control Channel, HS-DPCCH channel) is used for the carries downlink direction and modulates needed CQI quality feedback information; E-DCH Dedicated Physical Data Channel (E-DCH Dedicated Physical Data Channel, E-DPDCH channel) is in order in the uplink direction carrying user data; E-DCH Dedicated Physical Control Channel (E-DCH Dedicated Physical Control Channel, E-DPCCH channel) is in order to carry the rate information relevant with E-DPDCH, retransmission information etc. at uplink direction.
In communication system, two basic manipulation modes at terminal are idle pulley and connection mode.Connection mode can further be divided into different state: Universal Mobile Telecommunications System wireless access network registration area PCH state (Universal mobile telecommunication system Radio access network Register area Paging Channel; The URA_PCH state), cell paging channel status (CELL Paging Channel; The CELL_PCH state), cell forward access channel status (CELL Forward Access Channel; The CELL_FACH state), cell dedicated channel status (CELL Dedicated Channel; The CELL_DCH state), these states have defined the kind of operable physical channel in terminal and transmission channel.
Under the CELL_FACH state, uply can adopt high-speed uplink packet access technology, send uplink user data through the E-DCH channel; Descendingly can adopt high speed downlink packet access technology, receive down user data through the HS-DSCH channel.Under this state, radio network controller is unique terminal iidentification at reception HS-DSCH of terminal distribution: the H-RNTI sign.Radio network controller is unique terminal iidentification that sends E-DCH of terminal distribution: E-DCH Radio Network Temporary Identifier (E-DCH Radio Network Temporary Identifier, E-RNTI sign).The radio network controller information that terminal distribution H-RNTI identifies and E-RNTI identifies is for this reason informed Node B (NodeB) and terminal.
Business in similar " always online " type; For example: propelling movement of Email (PUSH Email) or virtual connection etc.; Need between terminal and server, frequently transmit or receive the parcel data; When network design, can adopt resident CELL_FACH state to realize, avoid frequently arriving the state transition of CELL_DCH.In addition, smart mobile phone is utilization in a large number in wireless communication system, need promote the service efficiency, the particularly service efficiency of E-DCH channel of the up line link of existing communication network as much as possible.
Because the HS-DPCCH channel is necessary on IA High Speed Channel, carrying out effective downlink data transmission.Under the situation that does not have CQI information, IA High Speed Channel is merely able to carry out blind modulation, and the remarkable decline that this will cause HSDPA throughput peak value makes the use of high speed resource become poor efficiency and waste.
In the prior art, when the terminal when up direction transmits data through E-DCH, HS-DPCCH just has chance and is sent out.In most scenes, when HS-DPCCH acquisition chance opportunity can be sent, at this moment descending possibly not have data to send, so the information that HS-DPCCH provided is seldom useful or useless at all.Simultaneously; The terminal need be waited at up direction can begin to send the data on the E-DCH after the protection period of conflict solution finishes; Like this, send the leading E-RNTI that detects this terminal to NodeB of first PRACH from the terminal, arrive HS-DPCCH again and send; Have time delay for a long time in the middle of this, make information that HS-DPCCH provided be desirable to provide IA High Speed Channel in time feedback decide the original intention of descending scheduling to differ bigger.
