Description
Technical field
The present invention relates to the ZAP in radio communication, particularly relate to a kind of method for determining uplink auxiliary carrier and radio network controller of terminal.
Background technology
In a wireless communication system, air interface refers to the interface between terminal (UE, UserEquipment) and Access Network (UTRAN, UniversalTerrestrialRadioAccess), be called for short Uu interface, be usually also referred to as wave point.Radio interface protocols is mainly used for setting up, reshuffling and discharge various wireless bearer service.
Third generation partner program (3GPP, 3rdGenerationPartnershipProject) introduce two carrier wave high-speed downlink packet access (HSDPA at the 8th version (Rel-8), HighSpeedDownlinkPacketAccess) technology, utilizes two descending adjacent carriers (main carrier and auxiliary carrier wave) to improve downlink bandwidth.Main carrier corresponding with service high speed descending sharing channel (HS-DSCH, HighSpeedDownlinkSharedChannel) community, the corresponding auxiliary serving HS-DSCH cell of auxiliary carrier wave.Main carrier and auxiliary carrier wave arrange high-speed physical downlink shared channel (HS-PDSCH) (HS-PDSCH respectively simultaneously, and High-Speed Shared Control Channel (HS-SCCH HighSpeedPhysicalDownlinkSharedChannel), and independently dispatch HighSpeedSharedControlChannel).For having the UE receiving two carrier wave High-Speed Shared Control Channel (DC-HSDPA, DualCarrierHighSpeedSharedControlChannel) abilities, HSDPA data can be received at downlink main carrier to carry and descending auxiliary carrier wave simultaneously.
In order to realize DC-HSDPA function, descending auxiliary cell information is configured to having the terminal receiving DC-HSDPA ability by Uu mouth by radio network control entity.So-called descending auxiliary cell information mainly comprises: option and installment information (maintaining mark or new configuration flag).New configuration information comprises high speed descending sharing channel Radio Network Temporary Identifier (HS-DSCHRNTI), downstream arrangements 64 phase quadrature amplitude modulation (64QAM), high speed descending sharing channel transmission block size table, downlink scrambling code, High-Speed Shared Control Channel channelization code information, measures power deviation, global communication wireless access Absolute Radio Frequency Channel number (UARFCN, UTRAAbsoluteRadioFrequencyChannelNumber).Wherein, HS-DSCHRNTI is for being identified at the terminal in certain community with HS-PDSCH.
3GPP introduces two carrier wave High Speed Uplink Packet access (DC-HSUPA at Rel-9, DualCarrierHighSpeedUplinkPacketAccess) technology, utilizes two up adjacent carriers (main carrier and auxiliary carrier wave) to improve upstream bandwidth.Main up-link carrier and auxiliary up-link carrier arrange respective enhancing Dedicated Physical Data Channel (E-DPDCH respectively, E-DCHDedicatedPhysicalDataChannel) and strengthen Dedicated Physical Control Channel (E-DPCCH, E-DCHDedicatedPhysicalControlChannel).Main descending carrier and auxiliary descending carrier arrange respective enhancing absolute grant channel (E-AGCH respectively, E-DCHAbsoluteGrantChannel), Relative Grant Channels (E-RGCH is strengthened, E-DCHRelativeGrantChannel) and strengthen hybrid automatic repeat-request channel (E-HICH, E-DCHHARQAcknowledgementIndicatorChannel).Main up-link carrier is corresponding with main descending carrier, and auxiliary up-link carrier is corresponding with auxiliary descending carrier.Main carrier and auxiliary carrier wave are independently dispatched.For having the UE sending DC-HSUPA ability, HSUPA data can be sent at main up-link carrier and auxiliary up-link carrier simultaneously.
If a up-link carrier configures to UE, then this up-link carrier is exactly main up-link carrier.When two up-link carriers are configured to this UE, UE may up at two on respectively have one serve enhanced data channel (E-DCH, EnhancedDedicatedChannel) community.The carrying frequency transmitting the serving E-DCH cell corresponding with service high-speed downlink shared channel community is called main up-link carrier.Up main carrier has a serving E-DCH cell, namely receives the community of the danger spot mandate (AG) from NodeB scheduler.The carrying frequency transmitting another one serving E-DCH cell is called auxiliary up-link carrier.Auxiliary up-link carrier has zero or a serving E-DCH cell, the serving E-DCH cell on auxiliary up-link carrier is called auxiliary serving E-DCH cell.
In order to realize DC-HSUPA function, up auxiliary cell information configures to having the UE receiving DC-HSUPA ability by radio network control entity.So-called up auxiliary cell information, mainly comprises: option and installment information (maintaining mark or new configuration flag).New configuration information comprises the downlink information of auxiliary serving E-DCH cell information, the public part of auxiliary E-DCH information and each the wireless link list in auxiliary upstream frequency.Wherein, auxiliary service E-DCH road cell information contains main E-DCH Radio Network Temporary Identifier and auxiliary E-DCH Radio Network Temporary Identifier.The parameter that the public part of auxiliary E-DCH comprises has: frequency information, scrambler type of coding, scrambling code number, 2 milliseconds of scheduled transmission mandate hybrid automatic repeat-request (HARQ, HybridAutomaticRepeatRequest) process distributes, authorization of service, inceptive service authorization value, primary/secondary mandate optant, minimum minimizing E-DPDCH gain factor, E-DCH minimal set E-DCH transformat merges instruction (E-TFCI, E-DCHTransportFormatCombinationIndicator), for the Dedicated Physical Control Channel (DPCCH of auxiliary upstream frequency, DedicatedPhysicalControlChannel) power bias, and power control preamble (PCpreamble).Wherein, the downlink information of each the wireless link list in auxiliary upstream frequency contains the downlink information of each wireless link in auxiliary upstream frequency, namely primary common pilot control channel information is had, cell ID, descender DPCH (the F-DPCH of each wireless link in auxiliary upstream frequency, FractionalDedicatedPhysicalChannel), enhanced data channel absolute grant channel information (E-AGCHInfo), enhanced data channel hybrid automatic repeat request indication channel information (E-HICHInformation), enhanced data channel Relative Grant Channels (E-RGCH) information option.Auxiliary upstream frequency is by primary common pilot control channel information, and namely main scrambler determines each community on auxiliary downstream frequency.
Above-mentioned DC-HSDPA and DC-HSUPA two functions all belong to two cell conditions, and namely descending have two serving HS-DSCH cell, and one is the serving HS-DSCH cell corresponding with main descending carrier, and one is the auxiliary serving HS-DSCH cell corresponding with auxiliary descending carrier.The uplink and downlink frequency of two serving HS-DSCH cell all belongs to same frequency range, and the frequency interval of two serving HS-DSCH cell is identical.
Along with technical development, multi-carrier high-speed downlink packet access technology wishes to be introduced into existing system, this technology makes UE on two carrier waves or plural carrier wave, can receive data with high speed downlink packet access technology, thus downlink data rate is doubled, and corresponding up carrier number can be one to four carrier waves.
That one deck carrier wave that in downlink double/multi-load ripple, UE is first resident is called main descending carrier, other layer of carrier wave remaining in downlink double/multi-load ripple is called auxiliary descending carrier, is called auxiliary descending carrier one, auxiliary descending carrier two, auxiliary descending carrier three (if having the 4th layer of carrier wave) respectively according to the sequential index of high level configuration.Current technological trend, being envisioned for of multi-carrier high-speed downlink packet access technology can have at most four layers of carrier wave on downlink main carrier to carry and three descending auxiliary carrier waves, to receive HSDPA data for UE simultaneously.
Main descending carrier corresponding with service HS-DSCH community, three auxiliary carrier wave also corresponding three serving HS-DSCH cell, are called auxiliary serving HS-DSCH cell.
For multi-carrier high-speed downlink packet access technology, remove beyond main descending carrier, at least also have two or three auxiliary descending carriers, then just have 3 or 4 serving HS-DSCH cell, as shown in Figure 1, corresponding 4 communities: community 1, community 2, community 3 and community 4.Wherein, it is main serving HS-DSCH cell that UE resides in community 2, and community 1, community 3 and community 4 are auxiliary serving HS-DSCH cell.Specify according to current industry, from these three communities of community 1, community 3 and community 4, select the frequency of up frequency as the upstream auxiliary carriers of UE of a community.Determine the definition of auxiliary serving E-DCH cell according to current industry, be in the community of auxiliary downlink reception to the absolute grant of NodeB scheduler.According to this rule, as shown in Figure 1, if UE receives absolute grant in the descending of community 4, then UE can think that community 4 is auxiliary serving E-DCH cell, and according to the regulation of auxiliary upstream frequency, the up frequency of community 4 is exactly the frequency of the auxiliary up-link carrier of UE.But, the up frequency of community 4 and the up frequency of community 2 are obviously non-conterminous, the current UE of this situation does not support, because UE only supports the situation of the upstream auxiliary carriers adjacent with up main carrier at present, if up non-conterminous frequency transmission can cause the cost up of terminal to want UE to support, and easily causes the interference to the non-frequency of utilization in centre.
