Embodiment 1

[0026] see figure 1 , the present embodiment improves the method steps of LTE PUCCH DTX detection performance as follows:

[0027] The first step is to initialize (step 11), calculate the NI power of all UEs in different time slots and different antennas (step 12), and calculate it as P n (slot i , ant j ), where i=0,1;j=0,1,...,M-1; M is the number of receiving base station antennas; the calculation formula is simply shown as follows:

[0028] Power_Win ant (t,s,c)=|win ant (t,s,c)| 2

[0029] P slot 0 = Σ ant Σ s pilot Power _ Win ant ( 0 , s pilot , c ) + Σ ...

Abstract

The invention provides a method for improving LTE PUCCH DTX detection performance. The method includes the steps that firstly NI flattening treatment among time slots and antennas is conducted on UE equilibrium demodulation data, then DTX detection and PUCCH demodulation treatment is conducted. After the scheme is used, under the scene with the large NI difference, the performance of simulation environment and implementation environment is greatly improved; under the scene with small NI difference, the performance of the simulation environment and the implementation environment is not lost, comprehensively, on the premise that the false-alarm probability reaches the standard, the miss-alarm probability of a PUCCH is greatly lowered, therefore, the wireless performance of the PUCCH is improved, and then the throughput performance of a whole LTE system is improved.

Description

technical field [0001] The invention relates to the technical field of wireless performance improvement in a wireless communication system, in particular to a method for improving LTE PUCCH DTX detection performance. Background technique [0002] LTE has always been favored by the mobile communication industry. With the development of LTE technology, more and more world-leading operators have adopted LTE as the future-oriented network evolution direction, and equipment manufacturers have also increased their investment in the LTE field, thereby promoting the continuous advancement of LTE. Compared with 3G (3rd Generation), LTE has the following technical characteristics: (1) reduce the cost per bit and increase the data rate of uplink and downlink communication; (2) increase the spectral efficiency and flexibly use existing and new frequency bands; (3) ) QoS (Quality of Service) guarantees, expands service provision capabilities, and provides more services with lower cost a...
