Abstract:
1. A method for selecting a Modulation and Coding Scheme (MCS), comprising: adjusting a range of an average Carrier to Interference Plus Noise Ratio (CINR) in a reference MCS parameter by a receiver according to interference plus noise power of a measuring sub-frame; calculating and obtaining an average CINR in a predetermined period by the receiver according to average interference plus noise power of the measuring sub-frame in the predetermined period; and determining MCS information by the receiver by comparing the adjusted range of the average CINR based on the calculated and obtained average CINR in the predetermined period; wherein the step of adjusting a range of an average Carrier to Interference Plus Noise Ratio (CINR) in a reference MCS parameter by a receiver according to interference plus noise power of a measuring sub-frame comprises: obtaining the interference plus noise power p(n) of the measuring sub-frame by the receiver; calculating and obtaining an average value P(n) and variance V(n) of the interference plus noise power p(n) of the measuring sub-frame in the predetermined period by the receiver; calculating and obtaining an pre-estimated adjustment amount of the range of the average CINR in the reference MCS parameter by the receiver according to the average value P(n) and the variance V(n); and adjusting the range of the average CINR in the reference MCS parameter by the receiver according to the pre-estimated adjustment amount.
