The allocation strategy from the frequency point 4 to the frequency point N is the same as that of the frequency point 3.
It should be noted that, when the PDCCH information of the nth radio frame indicates that the next M radio frames transmit the first PDSCH information, the indication information of the remaining frequency points PCFICH of the following M radio frames is only indicated as the first PDSCH information. Here, the first PDSCH information updates PDSCH information for system information. That is to say, only when the PDCCH information of the previous radio frame of the radio frames indicates that the next M radio frames transmit the first PDSCH information, the indication information of the remaining frequency points PCFICH of the radio frames in the present invention indicates that the first PDSCH information can be indicated.
The first PDSCH information may be understood as system information updating PDSCH information, and the second PDSCH information may be understood as downlink PDSCH traffic information.

the 1 st to 2 nd OFDM symbols of the second frequency point occupied by the UE are allocated as PCFICH2, and the 3 rd to 13 th OFDM symbols of the second frequency point and all OFDM symbols of the other frequency points are allocated according to the second indication information, including:
when the second indication information is second PDSCH information, allocating the 3 rd to 13 th OFDM symbols of the second frequency point and all the OFDM symbols of the rest frequency points as a second PDSCH;
when the second indication information is not the second PDSCH information, all OFDM symbols of the second frequency point and the rest frequency points are allocated according to a second allocation strategy;
the second allocation policy includes:
allocating the 5 th to 13 th OFDM symbols of the second frequency point according to the second indication information;
the 1 st to 2 nd OFDM symbols of the rest frequency points are allocated as PCFICH, and the 5 th to 13 th OFDM symbols of each frequency point in the rest frequency points are allocated according to the indication information of the PCFICH in the corresponding frequency point;
and the other frequency points are the other frequency points except the first frequency point and the second frequency point in the frequency points occupied by the UE.
