Description
Technical field
The present invention relates to improve in a kind of TD-SCDMA (TD SDMA) communication system method and the device that detects performance; Specifically, relate in the TD-SCDMA system, in default distributing mode, use the information of transformat combination directive (Transport Format Combination Indicator is called for short TFCI) to improve method and the device that detects performance.
Background technology
In the receiving system of TD-SCDMA, transformat combination directive TFCI will indicate the information of receiving system physical coded combination transfers information, in case obtain the value of TFCI, just can decode accordingly to transmission channel.TFCI transmits on first radio frames on each Transmission Time Interval minimum code channel of (Transmission Time Interval is called for short TTI), and keeps constant in whole Transmission Time Interval.
System assignment does not always use full for all code channels of targeted customer.System increases power system capacity simultaneously for the interference that reduces between the user, the number of the channel code that system uses will change according to the actual needs of business, therefore need the actual operating position of targeted customer's channel code be detected, the code channel of this actual use is called as activated code channel, and this targeted customer's real data is handled.
For the situation of change of adaptive system business, during the code channel number that uses when system and system assignment inconsistent, need the code channel situation that activate be detected, in order to the activation situation of judgement code channel.Because the gain of the spread spectrum of system is lower, when using conventional algorithm to detect code channel, error rate is higher, therefore be easy to cause the situation of code channel omission and flase drop, especially in the time of the code channel omission, to cause system data to lose and cause the severe exacerbation of demodulation performance, under the kindred circumstances, flase drop also will cause the reduction of systematic function.
When the method for salary distribution of the movement training sequence of system is used default distributing mode (DEFAULTMODE), owing to there is relation one to one between the training sequence of system and the code channel, when mistake appears detecting in the distribution that movement training sequence occurs, also will cause the detection mistake of code channel, and finally cause the receptivity of system to descend.
Summary of the invention
The object of the present invention is to provide a kind of method and device that detects performance that in default distributing mode, improve, utilize the TFCI accurately that calculates in first radio frames, determine the method that code channel detects and movement training sequence detects in the residue subframe except that first radio frames; This method can avoid just going out the situation of active valid data in first radio frames, improve the performance of receiving system.
For reaching above-mentioned purpose, the invention provides a kind of method that detects performance that in default distributing mode, improves, comprise following steps: step 1, judge whether this targeted customer's current physical coded combination transfers information contains the transformat combination directive: if contain transformat combination directive, execution in step 2; If do not contain transformat combination directive, redirect execution in step 6; Step 2, to first radio frames in each Transmission Time Interval of this targeted customer, carry out the detection of activated code channel and movement training sequence, be used to measure the effective movement training sequence that this targeted customer and other users may exist and the situation of activated code channel; The code word of step 3, transformat combination directive is resolved: after receiving first radio frames, the code word of transformat combination directive is decoded, obtain the value of the transmitted codewords in this Transmission Time Interval; Step 4, calculate this targeted customer in the activated code channel of this physical coded combination transfers information and the effective situation of movement training sequence; Step 5, according to the result that step 4 obtains, in remaining Transmission Time Interval, the testing result of relevant code track and movement training sequence is set directly; Step 6, effective movement training sequence of exporting this targeted customer and the information of activated code channel.
In the described step 2, at the sign indicating number detection-phase, can be by a detection threshold be set, the code channel that detects effective movement training sequence and be activated.
In the step 2, the setting principle of described detection threshold is: make as much as possible movement training sequence and code channel determined be effectively to activate.
In the step 2, described detection threshold can be arranged to: measuring all movement training sequence and code channel all is effectively to activate.
In the described step 4, can be according to the regulation of 3GPP TS 25.222 agreements, calculate the rate information of the business of this targeted customer on this physical coded combination transfers information, thereby calculate targeted customer's's this moment the activated code channel and the information of effective movement training sequence.
In the described step 5, in remaining Transmission Time Interval, do not carry out the detection of movement training sequence and activated code channel, direct effective activation situation according to movement training sequence in first radio frames in the Transmission Time Interval that calculates in the step 4 and code channel, the result that corresponding setting detects, the i.e. activation value of movement training sequence and code channel among the targeted customer.
Correspondingly, a kind of device that detects performance that improves in default distributing mode comprises: judge whether this targeted customer's current physical coded combination transfers information contains the module of transformat combination directive; To first radio frames in each Transmission Time Interval of this targeted customer, the module of carrying out the detection of activated code channel and movement training sequence; The code word parsing module of transformat combination directive after receiving first radio frames, is decoded to the code word of transformat combination directive, obtains the value of the transmitted codewords in this Transmission Time Interval; Calculate this targeted customer in the activated code channel of this physical coded combination transfers information and the module of the situation of effective movement training sequence; In remaining Transmission Time Interval, the testing result of relevant code track and movement training sequence module is set; This targeted customer's the effective movement training sequence and the message output module of activated code channel.
Method and the device that detects performance that in default distributing mode, improve provided by the invention, can overcome significantly because the movement training sequence of system and active coding detect the decline of the systematic function that error caused, can reduce simultaneously the operand of the detection algorithm of system, improve the performance of receiving system.
