Description
Technical field
The present invention relates to the method that the carrier pairing information in a kind of wireless communication system transmits, refer more particularly to abnormality eliminating method and the system of the transmission of a kind of carrier pairing information.
Background technology
3GPP (3rdGenerationPartnershipProject, third generation partner program) introduce DC-HSDPA (DualCellHighSpeedDownlinkPacketAccess at Rel-8, two carrier wave high-speed downlink packet access), utilize two descending adjacent carriers (main carrier and auxiliary carrier wave) to improve downlink bandwidth.Main carrier corresponding with service HS-DSCH (HighSpeedDownlinkSharedChannel, high speed descending sharing channel) community, the corresponding auxiliary serving HS-DSCH cell of auxiliary carrier wave.Main carrier and auxiliary carrier wave arrange HS-PDSCH (HighSpeedPhysicalDownlinkSharedChannel respectively simultaneously, high-speed physical downlink shared channel (HS-PDSCH)) and HS-SCCH (HighSpeedSharedControlChannel, High-Speed Shared Control Channel), and independently dispatch.For having the terminal receiving DC-HSDPA ability, HSDPA data can be received at downlink main carrier to carry and descending auxiliary carrier wave simultaneously.
In order to realize DC-HSDPA function, additional high-speed cell information wireless link cell is configured to Node B (NodeB) or another RNC by Iub mouth/Iur mouth by RNC (RadioNetworkController, radio network control entity).So-called additional high-speed cell information wireless link cell, mainly comprises: the auxiliary information on services of high-speed physical downlink shared channel (HS-PDSCH) wireless link identification, cell ID, high speed descending sharing channel and the total maximum bit rate of terminal.
3GPP introduces two carrier wave HSUPA (HighSpeedUplinkPacketAccess at Rel-9, High Speed Uplink Packet accesses) (DC-HSUPA), utilize two up adjacent carriers (main carrier and auxiliary carrier wave) to improve upstream bandwidth.Up main carrier and upstream auxiliary carriers arrange respective E-DPDCH (EnhancedDedicatedPhysicalDataChannel respectively, strengthen Dedicated Physical Data Channel) and E-DPCCH (EnhancedDedicatedPhysicalControlChannel strengthens Dedicated Physical Control Channel).Downlink main carrier to carry and descending auxiliary carrier wave arrange respective E-AGCH (EnhancedAbsoluteGrantChannel respectively, strengthen absolute grant channel), E-RGCH (EnhancedRelativeGrantChannel, strengthen Relative Grant Channels) and E-HICH (E-DCHHARQAcknowledgementIndicatorChannel strengthens dedicated channel hybrid automatic repeat-request channel).Up main carrier is corresponding with downlink main carrier to carry, and upstream auxiliary carriers is corresponding with descending auxiliary carrier wave.Main carrier and auxiliary carrier wave are independently dispatched.For having the UE (UserEquipment, subscriber equipment) sending DC-HSUPA ability, HSUPA data can be sent at up main carrier and upstream auxiliary carriers simultaneously.
If only have a up-link carrier to configure to terminal, then this up-link carrier is exactly up main carrier.When multiple up-link carrier is configured to this terminal, terminal has one to serve enhanced data channel community receiving on up main carrier from the absolute grant of Node B, terminal also has one to serve enhanced data channel community receiving on auxiliary up-link carrier from the absolute grant of Node B, is exactly up main carrier by service enhanced data channel community corresponding for service high-speed downlink shared channel community by the carrying frequency transmitted.Service high-speed downlink shared channel wireless link comprises all high-speed physical downlink shared channel (HS-PDSCH) physical channels distributing to this terminal, therefore high-speed physical downlink shared channel (HS-PDSCH) physical channel is exactly downlink main carrier to carry.Service high speed descending sharing channel community is to perform the wireless link transmission of service high-speed downlink shared channel and reception to some terminals.Define according to up main carrier, it corresponds to downlink main carrier to carry.
In order to realize DC-HSUPA function, RNC will be added enhanced data channel cell information and be configured to Node B (NodeB) or another RNC by Iub mouth/Iur mouth wireless link request.The request of so-called additional enhancing data channel cell information wireless link, mainly comprises: multiple cell E-DCH (EnhancedDedicatedChannel strengthens dedicated channel) transmission bearer pattern and additional E-DCH cell information are set up.Additional E-DCH cell information foundation comprises additional E-DCH channeling duplex and sets up information and multiple cell E-DCH information.Additional E-DCH channeling duplex is set up information and is comprised uplink special physical channel information, for setting up the additional peculiar information of E-DCH wireless link, additional E-DCH channeling duplex information and F-DPCH information.Be exactly the peculiar information of E-DCH additional radio links for setting up the additional peculiar information of E-DCH wireless link, it comprises the peculiar data entries of E-DCH additional radio links 1 and the peculiar data entries 2 of E-DCH additional radio links.The peculiar data entries of E-DCH additional radio links 1 has the following information: E-DCH additional radio links mark, cell ID, first wireless link collection instruction, propagation delay, initial downlink through-put power, primary common pilot control channel signal to noise ratio, some downlink channel power side-play amounts, and the media of additional E-DCH get involved the distinctive information of control dedicated stream.The peculiar data entries of E-DCH additional radio links 2 is the peculiar information of multiple cell E-DCH wireless link namely.
Along with technical development, multi-carrier high-speed downlink packet access technology is introduced into existing system, this technology makes terminal on two carrier waves or plural carrier wave, can send data with high speed downlink packet access technology, thus the transmission rate of down link data is doubled, and corresponding descending carrier number can be one to four carrier waves.
Inventor finds: for the uplink carrier frequencies of each activation, if UE is configured with 3 to 4 downstream service HS-DSCH communities, in this case, up E-DCH control channel should be launched in the serving HS-DSCH cell of pairing, and namely should there be pair relationhip up E-DCH Serving cell with downstream service HS-DSCH.Upstream service E-DCH cell ID is obtained by the cell ID cell in the peculiar information of E-DCH additional radio links in wireless link request message or wireless link reconfigured request or wireless link increase request; The cell ID cell that serving HS-DSCH cell mark is set up in information by HS-DSCH community additional radio links obtains.Descending introducing multicarrier (3 carrier waves or 4 carrier waves), main serving E-DCH cell identifies identical with main serving HS-DSCH cell, 2 or 3 auxiliary carrier waves are had due to descending, need auxiliary serving E-DCH cell to identify to be in the mark of multiple auxiliary serving HS-DSCH cell, but there will be in practical application auxiliary serving E-DCH cell mark identify with multiple auxiliary serving HS-DSCH cell in any one is all inconsistent, causing cannot by auxiliary serving HS-DSCH cell to terminal transmission data.For this problem, at present effective solution is not yet proposed.
