Five subbands are wide and the 7th subband it is wide corresponding to SINR be 3dB, then can calculate the according to interpolation method or curve-fitting method
Two subbands are wide, the 4th subband is wide, the 6th subband is wide and the wide corresponding SINR of the 8th subband is 3dB.
Such as in the case of example three above, it is if calculating the wide corresponding SINR of the first subband in step 203
SINR corresponding to 5dB, the 4th subband are wide is 8dB, then it is wide to calculate the second subband according to interpolation method or curve-fitting method
SINR corresponding to corresponding SINR is 6dB, the 3rd subband is wide is 7dB.
Such as in the case of example four above, it is if calculating the wide corresponding SINR of the first subband in step 203
SINR corresponding to 3dB, the 8th subband are wide is 3dB, then it is wide to calculate the second subband according to interpolation method or curve-fitting method
It is 3dB to the wide corresponding SINR of the 7th subband.
In the embodiment of the present invention, part subband that base station is pre-configured with the configured bandwidth of terminal is a width of to be used for SRS transmission
Subband it is wide, base station is wide in the subband for SRS transmission, what receiving terminal was sent on the subband for SRS transmission is wide
