Description

A kind of processing method and device thereof of uplink interference load control

Technical field

The present invention relates to moving communicating field, particularly relevant for a kind of processing method and device thereof of wireless communication system user business.

Background technology

WCDMA (Wideband Code Division Multiple Access) system is based on the broadband cellular wireless communication system of CDMA, and the WCDMA system supports a greater variety of types of service and high data rate traffic transmittability more.HSUPA (High Speed Uplink Packet Access) is the enhancement techniques of WCDMA system to the uplink ability.The HSUPA technology has comprised shorter TTI (TransmissionTime Interval), scheduler and HARQ (Hybrid AutomaticRetransmission reQuest) based on Node B, new transmission channel E-DCII (Enhanced Dedicate Channel) has adopted these key technologies, the HSUPA system can be significantly improved on the transmission performance of uplink service than traditional WCDMA version, the increase of nearly 50%-70% on power system capacity, the minimizing of 20%-55% is arranged, 50% the increase of on the user grouping calling flow, having an appointment in the delay of end-to-end grouping bag.Use the WCDMA system of HSUPA technology, comprised RNC (Radio Network Controller), Node B and UE (User Equipment).Wherein comprised some sub-districts (Cells) among the Node B, the sub-district is to be the common radio resources of UE service in the same area in the system, in HSUPA, by the sub-district can measuring system the ascending load degree.Node B is that unit finishes with the sub-district to the scheduling of UE.In HSUPA, the function that customer service is controlled and dispatched has been placed among the Node B, by the dispatch request (Scheduling Request) of Node B according to customer service, the seizure condition of customer service buffering area (Buffer Occupancy Status), the priority level of Business Stream (Priority), the uplink interference of sub-district and load be the disposal ability of base station, different UE is sent different authorization command (Grants), UE is according to the authorization command of Node B, in the E-TFC table (Enhanced Transport Format Combination Table) of the pre-configured UE of giving of RNC, select suitable transformat to merge (Enhanced Transport Format Combination), and use the pairing power excursion of this E-TFC (Power Offset), in a Transmission Time Interval (TTI), send and the data of authorizing corresponding size to Node B.The functional structure of HSUPA system is with reference to figure 2.

In HSUPA, authorize and be divided into absolute grant AG (Absolute Grants) and relative authorization RG (Relaive Grants), AG has specified the absolute size that allows the data volume pairing transmitting power ratio that UE can send, be also referred to as authorization of service (Serving Grants), and RG has specified and has allowed the relative size that UE can the transmitting power ratio, this relative size is to express with the mode of step-length, and its value can be UP (improving the scheduling amount of a step-length), DOWN (reducing the scheduling amount of a step-length) and HOLD (keeping existing scheduling amount).

The WCDMA system is a multi-user's a cdma wireless system, because in the sub-district of WCDMA system, the time of up UE emission is asynchronous, caused the nonorthogonality of up send channel between the different UEs, also just caused up the interfering with each other of transmitting of different UEs, therefore exist up UE send channel number many more in the sub-district, or the transmitting power of UE big more (SG is big more), the uplink interference of system is just big more, this annoyance level is represented with RTWP (Received Total Wideband Power, received total wideband power).

The operation of WCDMA system must remain on up interference within the rational thresholding, otherwise system will collapse because of the power ramp of disturbing overload to cause or serious problems such as a large amount of UE call drops.

The WCDMA scheduler has been controlled data transmission rate and the transmitting power of each UE in the sub-district by AG and RG just, guarantees that the uplink interference of the sub-district that these UE loads produce can not surpass interference threshold.Therefore how according to the actual conditions of sub-district and UE, dynamically determine and data transmission rate and the transmitting power (being SG) of bringing in constant renewal in each UE is the key of HSUPA uplink scheduling and load control.

The method of determining and calculating the maximum SG of mandate of each UE adopts the algorithm among the 3GPP RAN1 meeting motion R1-040698 usually.According to this algorithm, scheduler every one based on Fixed Time Interval (for example 2ms or 10ms), according to UE buffer data what and power rating, current and historical UE transmission rate, factors such as the radio link quality of UE, and the residue load of sub-district, calculate the dispatching priority of each UE, adopt Greedy Filling strategy (as far as possible satisfying earlier the data transfer request of the highest UE of priority) then, calculate the assignable load of each UE respectively, and distribute new SG for each UE, and give each UE by AG and RG authorized appropriation according to sub-district residue loading condition.When this algorithm is in static environment at UE, the load of UE and the RTWP of sub-district are in state more stably, the loading condition that can be good at following the tracks of and reflecting UE and sub-district based on the UE load in the Fixed Time Interval (for example 2ms or 10ms) and RTWP measurement, but because all there are bigger variation in UE load that UE motion and decline cause and the variation of sub-district RTWP between each slot, therefore measuring based on the UE load in the Fixed Time Interval (for example 2ms or 10ms) and RTWP can't fine tracking and actual load and the RTWP of prediction, thereby cause in movement environment, it is bigger that the algorithm of measuring based on Fixed Time Interval (for example 2ms or 10ms) is subjected to the wireless propagation environment factor affecting, necessarily descending aspect the stability of a system and the systematic function than UE static situation.

The dispatching algorithm that (2ms or 10ms) measures at present based in short-term is owing to need every 2ms that the priority of all UE is calculated simultaneously, and all UE are carried out the calculating of load and the prediction of load, thereby produced bigger amount of calculation, the calculation process resource of system has been proposed higher requirement.
