Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of resource allocation methods and system that realizes presence of intercell interference control.
Background technology
In existing GSM; In order to improve up access capability; FDD (FrequencyDivision Duplex; FDD) and TDD (Time Division Duplex; Time division duplex) introduced up enhancing (Enhanced Uplink) technology at 3GPP (3rd Generation Partnership Project) Release6 and Release7 in succession, in Release7, introduced HSPA+ (High Speed PacketAccess Plus) technology again HSDPA/HSUPA (High Speed Downlink/Uplink PacketAccess, high-speed downstream/upstream packet inserts) is done further to optimize;
Wherein, in HSUPA, introduced the characteristic of N frequency again, i.e. a plurality of carrier frequency of each cell configuration.In multi-frequency-point community, if adopt the mode of little area overlapping, each sub-district (also being frequency) respectively has and overlaps independently resource distribution, on each frequency, all disposes a whole set of common signal channel simultaneously.Can cause some problems like this, for example: the cell code reuse is high, Cell searching is difficult, terminal measuring complex, the difficulty of switching, system effectiveness are low etc.N frequency technology preferably resolves this problem.The configurable a plurality of carrier frequency in sub-district are confirmed one of them as main carrier frequency, and other carrier frequency is an assistant carrier frequency, only on main carrier frequency, send DwPTS (descending pilot frequency time slot) and broadcast message common signal channels such as (TS0 time slots).
At first each channel of LCR (Low Chip Rate, low spreading rate) TDD HSUPA is briefly introduced below:
Transmission channel: E-DCH and E-UCCH;
Wherein, E-DCH (Enhanced Dedicated Transport Channel) is the transmission channel that strengthens, and is used for carrying uplink business data; And the ascending control channel of the up enhancing of E-UCCH (E-DCH Uplink Control Channel), the raw information of its carrying is following:
E-TFCI (E-DCH Transport Format Combination Indicator, the indication of E-DCH TFS Transport Format Set) comprises data block length, and the indication that can imply passes the data-modulated mode, takies 6bit; HARQ ID (Hybrid Automatic Repeat Request identification, mixed automatic retransmission request process sign) shows the HARQ process number, takies 2bit; RSN (Retransmission Number, retransmission sequence number) shows the number of transmissions, and what can imply indicates the RV parameter, takies 2bit;
And behind above-mentioned these information vias Reed Muller (32,10) coding, on E-UCCH, transmit.
Physical channel: E-RUCCH, E-AGCH, E-HICH and E-PUCH;
Wherein, E-RUCCH (E-DCH Random Access Uplink Control Channel; E-DCH inserts ascending control channel at random) comprise SI (Scheduling Information; Schedule information) the HSUPA ID E-RNTI of message and UE (E-DCH Radio Network Temporary Identity), it is used to send the access request of UE; E-AGCH (E-DCH Absolute Grant Channel, E-DCH absolute grant channel), down control channel sends the message such as physical resource and power that Node B (base station) distributes to UE; E-HICH (E-DCH HARQ Acknowledgement Indicator Channel; E-DCH HARQ answering indication signal channel) carries ACK/NAK (Acknowledgement/Negative Acknowledgement, the ack/nack is replied) message that Node B feeds back; E-PUCH (Enhanced Uplink Physical Channel, the uplink physical channel of enhancing), E-DCH and E-UCCH are multiplexed into this channel.
At present in the HSUPA system of N frequency,, distribute one or more E-AGCH, E-HICH control channel on E-PUCH physical channel resources and the corresponding carrier wave that needs to monitor on the carrier wave by RNC (radio network controller) for a UE; And in current agreement; During the UE access network; In RRC Connection Setup Request (the Radio Resource control connection is set up request) and RRCConnection Setup Complete (the Radio Resource control connection is set up and accomplished) signaling, ability information is reported network; Whether network based UE supports HSUPA; Notice Node B distributes E-PUCH shared resource pond and public E-AGCH/E-HICH control channel group information for this UE in the Radio of NBAP Link SetupRequest (Radio Link is set up request) or Radio Link Reconfiguration Prepare (radio link reconfiguration preparation) signaling; Node B will distribute to the E-AGCH/E-HICH control channel group notice RNC that UE monitors in Radio Link Setup Response (Radio Link is set up and responded) or Radio Link Reconfiguration Ready (radio link reconfiguration is ready), RNC notifies the E-AGCH/E-HICH control channel group of its monitoring of UE in RRCConnection Setup or Radio Bearer Setup.
Concrete, the transmitting-receiving process that HSUPA receives upstream data is following:
The SI information that Node B reports according to UE; UE is dispatched, for UE distributes corresponding power resource (PRRI, Power Resource Related Information), time interval resource (TRRI; TimeslotResource Related Information), code channel resource (CRRI; Code Resource RelatedInformation), the E-UCCH number (ENI, E-UCCH Number Indicator) used, the E-HICH channel number (EI at feeding back ACK/NACK place; E-HICH Indicator), these information are notified on E-AGCH and are given UE.UE is according to the scheduling grant information of Node B; Carry out E-TFC (E-DCHTransport Format Combination; The E-DCH TFS Transport Format Set) selects; Carry out data then and send, the TBS of use (Transport Block Size, transmission block size) size, HARQ information are through E-TFCI (E-DCH Transport Format Combination Indicator; E-DCH TFS Transport Format Set indication), HARQ Process ID, RSN send being multiplexed on the E-PUCH with E-DCH on the E-UCCH, the E-UCCH number of transmission is the value of Node B through the ENI indication.Node B is after receiving E-PUCH; Decode after earlier a plurality of E-UCCH being merged; According to the E-TFCI that solves, HARQ Process ID, RSN business datum is carried out the soft merging of HARQ back decoding; According to CRC (Cyclic RedundancyCheck, CRC) check results, ACK/NACK is fed back to UE on E-HICH.
And the HSUPA system is very big owing to the size variation span of transmission block, and according to the difference that UE is in subdistrict position, can produce either large or small interference to the adjacent area, and then influence the capacity of HSUPA system.
Summary; In present N frequency HSUPA system; HSUPA resource when UE sets up link is distributed by RNC; At present in the agreement not UE report the mechanism of its place subdistrict position, RNC does not consider the different of UE subdistrict position of living in initial resource allocation during with follow-up resource reprovision like this, the user of Resources allocation back edge sub-district causes bigger interference to the same frequency UE of adjacent sub-district probably like this.Even carry out resource reconfiguration according to mass measurement or load condition subsequently, but this needs the statistics of long period, in a period of time that the HSUPA business initial carries out, make system's work that can not be optimized.
