Embodiment 1

[0058] This preferred embodiment 1 describes the process that after the terminal accesses the base station, the terminal reports the bit error rate according to the instruction of the base station, and then the base station updates the modulation and coding mode according to the bit error rate.

[0059] image 3 It is a flow chart of the method for updating the modulation and coding scheme according to the preferred embodiment 1 of the present invention, including the following steps S302 to S310.

[0060] Step S302, after the terminal searches for the network, it tries to access it.

[0061] Step S304 represents the access signaling between the base station and the terminal, including basic capability negotiation, authentication process, registration process and so on.

[0062] It should be noted that step S302 and step S304 are the same as the standard WIMAX access process.

[0063] In step S306, the base station requests the terminal to report the bit error rate through a...

Embodiment 2

[0067] This preferred embodiment 2 describes in detail the process that after the terminal accesses the base station, the terminal reports the downlink bit error rate according to the base station's instruction, and then the base station updates the modulation and coding scheme according to the downlink bit error rate.

Embodiment 3

[0082] The third preferred embodiment describes in detail the process that the base station measures the uplink bit error rate after the terminal accesses the base station, and then updates the modulation and coding scheme according to the uplink bit error rate.

[0083] Figure 5 It is a flow chart of the method for updating the modulation and coding scheme according to the third preferred embodiment of the present invention, including the following steps S502 to S516.

[0084] Step S502, the base station receives an access message from the terminal.

[0085] Step S504, the base station obtains user configuration information from the AAA.

[0086] In step S506, the base station establishes a corresponding service flow according to the configuration information of the user. It should be noted that steps S502 to S506 are the same as the standard WIMAX access process.

[0087] In step S508, the base station configures a default upper limit of bit error rate and lower limit of...

Abstract

The present invention discloses a method and a base station (BS) for updating modulation and coding mode. The method comprises: the BS obtains Bit Error Rate (BER); said modulation and coding mode is updated according to the BER. The BS comprises an obtaining module to obtain BER, an updating module to update the modulation and coding mode according to the BER. The present invention resolves the problem of the throughput decline in the whole network caused by that a terminal uses Adaptive Modulation and Coding (AMC) demodulation signal based on channel quality information, thereby increasing the throughput of the whole network.
