Embodiment 1
[0049] The method embodiment provided in Embodiment 1 of the present application may be executed in a control terminal (such as a computer terminal or a similar computing device) on the transmitting device. Take running on a computer terminal as an example, such as figure 1 As shown, the computer terminal may include one or more (only one is shown in the figure) processors 101 (the processors 101 may include but not limited to processing devices such as microprocessor MCU or programmable logic device FPGA, etc.), for storing Data storage 103, and transmission means 105 for communication functions. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device.
[0050] The memory 103 can be used to store software programs and modules of application software, such as program instructions / modules corresponding to the control method of the device in the e...
Embodiment approach 1
[0066] image 3 Shown is a schematic diagram of division of the highest order modulation area of the physical resource block, the abscissa is the symbol (Symbol) series in the time domain, and the ordinate is the subcarrier (Subcarrier) series in the frequency domain. image 3 The shown physical resource blocks are 14 symbols in the time domain and 12 subcarriers in the frequency domain.
[0067] exist image 3 , area 1 is: all physical resources on the first symbol closest to the edges of the physical resource block in the time domain, and all physical resources on the first subcarrier closest to the edges of the physical resource block in the frequency domain physical resources. which is, image 3 All physical resources on symbols 1 and 14 in , and image 3 All physical resources of the 1st subcarrier and the 12th subcarrier in . which is image 3 The physical resource in the shaded part of the horizontal line is area 1. The highest order of modulation in Region 1 i...
Embodiment approach 2
[0070] Figure 4 Shown is a schematic diagram of division of the highest modulation order region of the physical resource block. The abscissa is the symbol series in the time domain, and the ordinate is the subcarrier series in the frequency domain. Figure 4 The shown physical resource blocks are 14 symbols in the time domain and 12 subcarriers in the frequency domain.
[0071] exist Figure 4 , area 1 is: in the time domain, all physical resources on the first and second symbols of the physical resource block closest to both edges, and in the frequency domain, the first symbol of the physical resource block closest to the two edges All physical resources on the carrier. which is Figure 4 All physical resources on the 1st symbol, 2nd symbol, 13th symbol and 14th symbol in , and Figure 4 All physical resources of the 1st subcarrier and the 12th subcarrier in . Figure 4 The physical resource in the shaded part of the horizontal line is area 1. The highest order of mod...
