Description
Technical field
The present invention relates to the transmission technology that channel quality in wireless communication system is indicated, a kind of transmission channel matter is particularly related to
The method and apparatus of amount instruction.
Background technology
CQI (Channel Quality Indicator, CQI), is the communication quality of wireless channel
Measurement index.CQI represents a metric for the channel measurement index of given channel.Generally, the CQI of a high level represents one
Channel has quality high, and vice versa.One CQI of channel is calculated by using performance parameter, the performance parameter for example,
Signal to noise ratio, i.e. Signal to Interference plus Noise Ratio or signal and noise distortion ratio etc..These values and other can weigh given
Channel measured value can comprehensively calculate the CQI of channel.One CQI of given channel can determine transmission for communication system selection
Or modulation scheme provides foundation.
In a communications system, high-speed downlink packet access (High Speed Downlink Packet Access,
HSDPA) technology can improve power system capacity, and can be obviously improved descending user data rate, can be at one 5 megahertzs
For Packet data service provides the downlink transmission data rate more than 10 MBPSs in bandwidth hereby.Changing in this performance
Kind, from some key technologies that it is used, these technologies include：Adaptive Modulation and Coding, fast dispatch is advanced to connect
Receipts machine design etc..High speed downlink packet access technology introduces a new transmission channel, high speed descending sharing channel
(High Speed Downlink Shared Channel, HS-DSCH channel), is used to carry the load of HSDPA, that is, be sent to
The business datum in terminal down link direction.Meanwhile, in order to ensure terminal can be decoded to the data on HS-DSCH,
HSDPA technologies also introduce a new physical channel, High-Speed Shared Control Channel (High Speed Shared Control
Channel, HS-SCCH channel), it is used to the information required for carrying HS-DSCH demodulation.Information on HS-SCCH is special with terminal
Fixed mark, i.e. HS-DSCH Radio Network Temporary Identifiers (HS-DSCH Radio Network Temporary
Identifier, H-RNTI are identified) carry out mask, so as to terminal can interpolate that information on the HS-SCCH for receiving whether be
It is sent to oneself.
High-speed uplink packet access technology is changed by the means such as fast dispatch and the merging of physical layer Fast retransmission
The performance of kind system for uplink packet data.High-speed uplink packet access technology introduces a kind of new transmission channel, enhanced
Dedicated transmission channel (Enhanced Dedicated Transport Channel, E-DCH channel), for carrying number of users
According to, and be single up direction.The physical channel of bearing reinforced dedicated transmission channel is Physical Random Access Channel (Physical
Random Access Channel, PRACH channel).Additionally, the physical channel that uplink direction may be used has：It is special
Physical control channel (Dedicated Physical Control Channel, DPCCH channel), for carrying physical layer power
Control information；High-Speed Dedicated Physical Control Channel (High Speed Dedicated Physical Control Channel,
HS-DPCCH channels), for the CQI quality feedback informations required for the modulation of bearing downlink link direction；The special physics numbers of E-DCH
It is believed that road (E-DCH Dedicated Physical Data Channel, E-DPDCH channel), in uplink direction
Carry user data；E-DCH Dedicated Physical Control Channels (E-DCH Dedicated Physical Control Channel,
E-DPCCH channels), to carry rate information, retransmission information related to E-DPDCH etc. in uplink direction.
In a communications system, two basic manipulation modes of terminal are idle mode and connected modes.Connection mode can be with
It is further separated into different states：Universal Mobile Telecommunications System wireless access network registration area PCH state (Universal
mobile telecommunication system Radio access network Register area Paging
Channel, URA_PCH state), cell paging channel state (CELL Paging Channel, _ FACH state), cell
Forward access channel status (CELL Forward Access Channel, CELL_FACH state), cell dedicated channel status
(CELL Dedicated Channel, CELL_DCH state), these states define physical channel that terminal can use with
And the species of transmission channel.
In the cell -- fach state, it is up to use high-speed uplink packet access technology, by E-DCH channels
To send uplink user data；It is descending to use high speed downlink packet access technology, received by HS-DSCH channels
Down user data.In this case, radio network controller is that terminal distribution one is receiving unique terminal of HS-DSCH
Mark：H-RNTI is identified.Radio network controller is one unique terminal iidentification of transmission E-DCH of terminal distribution：E-DCH without
Line Network Temporary Identifier (E-DCH Radio Network Temporary Identifier, E-RNTI mark).Wireless network
Controller will be the information of this terminal distribution H-RNTI marks and E-RNTI marks, advised nodes B (NodeB) and terminal.
The business of " always online " type is being similar to, for example：The push (PUSH Email) of Email or virtual link
Deng, it is necessary to frequently transmit or receive small bag data between terminal and server, in network design, can be using resident
CELL_FACH states are realized, it is to avoid frequently to the state transition of CELL_DCH.Additionally, smart mobile phone is in wireless communication system
In it is a large amount of use, it is necessary to lift the service efficiency of the up line link of existing communication network as far as possible, particularly E-DCH letters
The service efficiency in road.
For carrying out the transmission of effective downlink data on IA High Speed Channel it is necessary due to HS-DPCCH channels.Do not having
In the case of CQI information, IA High Speed Channel is merely able to carry out blind modulation, and this will cause being remarkably decreased for HSDPA throughput peaks, make
The use for obtaining high speed resource becomes poorly efficient and wastes.
In the prior art, when terminal transmits data in up direction by E-DCH, HS-DPCCH is only possible to have an opportunity
Sent.In most scenes, when HS-DPCCH obtains chance opportunity can be sent, now descending is probably no data hair
Send, therefore the few use of information or at all useless that HS-DPCCH is provided.Meanwhile, terminal is needed in up direction
Waiting the protection period of Conflict solving can start to send the data on E-DCH after terminating, and so, first be sent from terminal
The leading E-RNTI that this terminal is detected to NodeB of individual PRACH, then sent to HS-DPCCH, exist for a long time in the middle of this
Time delay so that information that HS-DPCCH is provided and fed back in time desirable to provide IA High Speed Channel and determine the original intention of descending scheduling
Difference is larger.
