Description

The method of measurement of the adjacent area interference of multi-carrier reinforced uplink access system
Technical field
The present invention relates to the communications field, and especially, relate to the method for measurement of the adjacent area interference of a kind of multi-carrier reinforced uplink access system.
Background technology
The enhanced uplink connecting system is commonly referred to as high speed uplink packet and inserts (High SpeedUplink Packet Access; HSUPA) system; The technology through the advanced person that its objective is improves the efficient of up link, thereby supports effectively that web browses, video, multimedia messages and other IP-based business.
3G (Third Generation) Moblie partnership (3GPP) has been accomplished the standardization effort of TD SDMA access (TD-SCDMA) enhanced uplink connecting system at present.This system is applicable to single carrier TD-SCDMA system.In enhanced uplink (EUL), increased a kind of transmission channel newly, that is, enhanced uplink dedicated transmission channel (E-DCH), enhanced uplink data is carried on this transmission channel, and the Transmission Time Interval of E-DCH (TTI) is 5ms.The grouping that is mapped on the E-DCH transmission channel is called enhancing media access control protocol data unit (MAC-e PDU).
The physical channel relevant with E-DCH is following:
Enhanced uplink control channel (E-UCCH): this channel is a physical layer control channel, and it is carried in the physical layer indication territory of E-PUCH, and control information wherein comprises: enhanced uplink transformat indication (E-TFCI) is used to indicate current transport block length; And mix automatic repeat requests (HARQ) information, comprising process ID and number of retransmissions information;
E-AGCH channel (E-DCH absolute grant channel), this channel is a control channel, is used to Node B (base station) transmission authorization message;
E-PUCH (the E-DCH uplink physical channel is claimed the enhanced uplink physical channel again), this channel is a Traffic Channel; Be used for UE (User Equipment, user terminal also can be called subscriber equipment) and carry the E-DCH transport channel data; In addition, relevant with auxiliary dispatching information is also in this channel;
E-RUCCH (E-DCH inserts ascending control channel at random, that is, enhanced uplink random inserts ascending control channel); This channel is a physical layer control channel; Being used for UE is not having under the situation of authorizing, the relevant information of transmission auxiliary dispatching, and E-RUCCH uses the Physical Random Access Channel resource;
E-HICH (E-DCH hybrid automatic repeat request indication channel), this channel is a physical layer control channel, is used to make Node B to carry HARQ (mixing automatic repeat requests) indication information.
The enhanced uplink access service can be divided into dispatching services and non-scheduling service by the difference of scheduling mode.Wherein, the resource of non-scheduling service is distributed for UE by RNC (radio network controller), and the method for salary distribution is with existing dedicated channel allocation mode; And in dispatching services, be that by Serving RNC (SRNC) Node B distributes the enhanced uplink resource pool, and be single UE Resources allocation by Node B.In dispatching services; UE need report the scheduling of some information with auxiliary Node B; These information are called schedule information SI (SchedulingInformation); Comprise path loss (path loss the abbreviates path loss hereinafter as) metrical information of UE buffer information, power headroom, Serving cell and adjacent sub-district etc. in this information.
Fig. 1 is the signaling process figure that the performed main business of each entity of relating to of dispatching services is handled.In the drawings, RNC 1 is NodeB 2 allocation schedule service resources ponds (102), be responsible for admits control (106) and according to NodeB the distribution (110) of dispatching services shared control channel is UE configuration schedules service bearer parameter (112); NodeB 2 returns response (104) according to the indication resource allocation pond of RNC, and is UE Resources allocation (116) according to the dispatch request of UE, carries out HARQ and confirms (120); When up when transfer of data is arranged UE 3 send dispatch request, to trigger the transmission (114) of schedule information, carry out the transmission (116 and 118) of data, and the reception of confirmation (120) according to the mandate of NodeB.
Comprise buffer information in the dispatch request information, path loss information, power margin information, wherein, path loss information is the NodeB control reference quantity to adjacent area interference, can draw the path loss ratio (SNPL) of adjacent sub-district and Serving cell through path loss information, its expression formula is:
Formula (1): Φ = 1 Σ n = 1 N L Serv / L n Or formula (2): Φ = Min n = 1 . . N ( L n ) L Serv
Wherein, L is the path loss that UE records, L ServBe Serving cell path loss, L nBe the neighbor cell path loss, UE need report this information, and Node B dispatches UE according to this information, and whether this information has determined UE to be scheduled and UE has been distributed authorization resources (comprising the mandate to power, code channel and time slot in this authorization resources).
For the throughput of further raising system, the single carrier enhanced uplink system in the correlation technique has introduced the multicarrier characteristic, and N carrier wave will have N doubly to the throughput of single-carrier system in theory.When introducing the multicarrier characteristic, with the consideration that has multiple framework, wherein a kind of feasible framework is a multicarrier binding mechanism, that is, UE can send the E-DCH data simultaneously on a plurality of carrier waves in a TTI, and the data block that each carrier wave sends is independently.This framework is adopted when HSDPA (high speed downlink packet access) introduces the multicarrier characteristic, it is advantageous that the peak rate that can improve single UE.
In above-mentioned multicarrier binding mechanism, the disturbed condition of each carrier wave that UE reports will determine NodeB in a TTI, to be the number of carriers of UE distribution and the authorization resources on each carrier wave.Because the major-minor carrier wave between neighbor cell is different; For example, the main carrier of Serving cell possibly be the auxilliary carrier wave of neighbor cell, and should possibly not have common downlink channel on the auxilliary carrier wave; In this case; UE can't directly measure the interference of neighbor cell on this carrier wave, and, the effective scheme how UE measures and how to report the information of each carrier wave is not proposed so far as yet.
