When the indicated channel carrier is available, the corresponding bit value is "1", and if not available, is indicated as "0". All the channel carriers are indicated, and one available channel carrier indication is formed, specifically, a Bitmap (Bitmap). Wherein grey represents that the channel carrier is an available channel carrier.

s110, obtaining and storing each available channel carrier indication of the discrete carrier system, and determining the mapping relation between each logic carrier sequence number and each available channel carrier based on each available channel carrier indication.
And acquiring the carrier indication of each available channel from the system information of the discrete carrier system. The indication is sent directly through a system message, specifically, a main system information block (MIB, master Information Block) is carried on a physical broadcast channel PBCH for transmission, so that the transmission efficiency of data can be improved, specifically, the data is transmitted through a downlink shared data channel PDSCH in downlink. In addition, the each available channel carrier indication includes: each available channel carrier of the discrete carrier system indicates a bitmap.
The method for determining the mapping relationship between each logical carrier sequence number and each available channel carrier based on the bitmap comprises the following steps: and mapping each logic carrier sequence number to each available channel carrier in sequence from small to large according to the sequence from low to high of each available channel carrier so as to form a mapping relation between each logic carrier sequence number and each available channel carrier.
