Problems solved by technology

However, the more information to report, the greater the corresponding uplink signaling overhead, which reduces the efficiency of uplink data transmission. Therefore, some good methods are needed to minimize the uplink signaling overhead under the premise of ensuring a certain scheduling gain.

Embodiment Construction

[0038] In order to solve the disadvantages of the traditional technical solutions, the present invention further elaborates a method for dynamically configuring channel quality indication quantization levels based on services in the present invention through the following specific examples. The specific implementation is described in detail below, but it is not intended to Limitations of Invention.

[0039] Such as figure 1 As shown, it is a flow chart of selecting CQI quantization levels according to service requirements. Include the following steps:

[0040] Step 101, identifying the corresponding relationship between different service types and bit error rate requirements; the bit error rate requirement here is an order of magnitude range;

[0041] Step 102, according to different bit error rate requirements, determine the corresponding CQI quantization level;

[0042] At this time, the corresponding relationship between the service type-bit error rate requirement-CQI qu...

Abstract

The invention discloses a method used for indicating quantization level on the basis of service dynamic configuration channel quality, comprising the steps as follows: (1) the corresponding relationship of different service types and bit error rate (BER) demand is identified; (2) according to different BER demands, corresponding CQI quantization level is determined; (3) according to the BER demands of current service type, corresponding CQI quantization level is selected; and (4) according to the CQI quantization level, the CQI feedback is compressed. The method changes the CQI quantization level dynamically according to difference service demands, reduces the number of transmission information bit and reduces the cost on the basis of meeting the service demands.

Description

technical field [0001] The invention relates to a Multiple-Input Multiple-Output MIMO (Multiple-Input Multiple-Out-put) wireless mobile communication system, in particular to a method for dynamically configuring channel quality indication quantization levels based on services. Background technique [0002] Now, the fourth generation communication standard IMT-advance standard of ITU (International Telecom Union International Telecommunications Union) plans to evolve the existing communication system. Among many physical layer transmission technologies, OFDM (Orthogonal Frequency Division Multiplexing technology) has become one of the most promising downlink solutions due to its high spectral efficiency and low processing complexity, and has become a B3G, 4G passway an important technology in [0003] OFDM technology is essentially a multi-carrier modulation communication technology. In the frequency domain, the OFDM multipath channel exhibits frequency-selective fading cha...
