Description
Technical field
The present invention relates to the 3G (Third Generation) Moblie field, the high-speed uplink packet access external circulation power control method and the network equipment when relating in particular to a kind of soft handover.
Background technology
Along with the continuous growth of mobile data services, the asymmetry of the up-downgoing traffic carrying capacity that the conventional wireless voice communication does not embody as yet will be given prominence to more and be embodied.Require wireless communication system itself must have some characteristics of suitable transmitting data service simultaneously.Third generation partner plan (3
RdGeneration Partnership Project, 3GPP) tissue has the asymmetric characteristics of up-downgoing according to data service, in the R5 version, introduce high speed downlink packet and insert that (High Speed Downlink Packet Access HSDPA) strengthens support to the downlink grouped data business.But, HSDPA does not possess the ability of supporting the up-high speed data service, can not support video telephone well, up-downgoing data volumes such as high-quality speech are than the business of balance, therefore, 3GPP has introduced High Speed Uplink Packet access (High Speed Uplink Packet Access in the R6 version, HSUPA) strengthen the uplink capability of 3-G (Generation Three mobile communication system), in protocol specification, be referred to as enhanced uplink (Enhanced Uplink), its main target is to improve the service efficiency of uplink air interface capacity, strengthens the coverage of cell throughout and up-high speed data service.These two kinds of wireless enhanced technology combine the communication of realization high speed symmetric data, support multimedia, video conference and based on the business such as voice of Internet Protocol.
For improving uplink speed, strengthen coverage rate, reducing time delay, HSUPA is with reference to the various technology that adopt among the HSDPA, but because code division multiple access (Code Division Multiple Access, CDMA) mobile communication system has very big difference on uplink downlink, uplink downlink is having remarkable difference aspect the processing of power control resource, power control and the near-far interference, when introducing up enhancement techniques, can not be transplanted to ascender to the key technology of HSDPA simply.HSUPA retransmits (Hybrid Automatic Repeat Request based on uplink packet fast dispatch, the mixing of Node B more flexibly automatically by use, HARQ) technology such as technology and high order modulation coding is up to the upstream data access service that the user can provide 5.8Mbps.
Present HSUPA exterior ring power control (Outer Loop Power Control, OLPC) method is to adjust Dedicated Physical Control Channel (Dedicated Physical Control Channel by control, DPCCH) signal conflict ratio desired value (Signal to Interference Ratio Target, SIR Target) and by reshuffling strengthen Dedicated Physical Control Channel (Enhanced Dedicated Physical Control Channel, E-DPCCH) and strengthen Dedicated Physical Data Channel (Enhanced Dedicated Physical Data Channel, power bias E-DPDCH) is realized.Detailed process is to adjust the desired value of SIR, and/or (Power Offset, PO), the average transmission number of times realizes and above-mentioned adjustment to SIR, PO mainly is based on to adjust power bias.Wherein, the average transmission number of times is an OLPC in the cycle, all medium access control entities (Medium Access Control-es, MAC-es) mean value of data re-transmission number of times, and the data re-transmission number of times is HARQ can the normal decoder data time, the number of times that this data accumulative total sends.If the number of retransmissions of data is little, can obtain less average transmission number of times so, just illustrated that also the quality of link is better, just can satisfy business need with less transmitting power.In soft handover, the increase of Radio Link all must guarantee subscriber equipment (User Equipment with release, UE) with universal mobile telecommunications system land radio access web (Universal Mobile Telecommunications System Terrestrial Ratio Access Network, UMTS-TRAN, UTRAN) keep a Radio Link between at least, under soft handoff condition, when UE is in soft changing state, and when having the Radio Link of at least two Node B, the HSUPA data arrive radio network controller (Ratio Network Controller, RNC) to merge (merging) time at MAC-es, to choose same HSUPA data, and this moment, the data of each Radio Link do not arrive simultaneously, just the number of retransmissions of the data of each access node Node B has difference, be the Node B of each Radio Link correspondence to report the data retransmission of same data may be different, prior art is that the number of retransmissions which wireless links data is the data when which wireless links just arrive first with calculates the average transmission number of times.
The inventor finds that in research process there are the following problems at least in the prior art:
Because the number of retransmissions that prior art is the data when which wireless links just to be arrived first with for which wireless links data calculates the average transmission number of times, the number of retransmissions that so just may choose the relatively large or maximum data of number of retransmissions calculates the average transmission number of times, thereby when the control exterior ring power, cause the waste of transmitting power.
