The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in much of the following description, but these techniques can also be applied to applications other than NR system applications, such as 6th ^generation Generation, 6G) communication system.

In order to facilitate understanding of the embodiments of this application, the following technical points are first introduced below:

1. About FDSS technology

After a set of discrete time domain signals passes through a Digital to Analog Converter (DAC) module, the peak-to-average ratio of the output analog signal has a certain relationship with the correlation between the set of discrete time domain data. Assume that a set of discrete time domain data signals y(n) and a set of time domain discrete data d(n) are subjected to time domain convolution to obtain yd(n):

Assume that the peak-to-average ratios of the output signals of y(n) and yd(n) after passing through the DAC are PAPR1 and PAPR2 respectively. If d(n) is a set of designed weight coefficients, then the adjacent data of yd(n) The correlation between them will be better than the correlation between adjacent data of y(n). The higher the correlation, the lower the PAPR, so PAPR2 will be smaller than PAPR1. After convolving a set of discrete time domain data with a set of designed discrete data, the PAPR can be effectively reduced.

According to the convolution theorem, the convolution operation of two time domain signals can be equivalent to the dot product operation of the two time domain signals in the frequency domain. Therefore, a set of discrete time domain data is converted into discrete frequency domain data through Discrete Fourier Transform (DFT), and then the designed spectrum shaping sequence is dot multiplied, and then through the Inverse Discrete Fourier Transform (Inverse Discrete Fourier Transform) , the time domain signal after IDFT) can effectively reduce PAPR. Since the dot product operation is less complex than the convolution operation, this PAPR reduction technology operates better in the frequency domain, so this technology is called FDSS technology.

2. Extension FDSS technology

When performing FDSS transmission, a few adjacent PRBs can be reserved to adjust the frequency domain waveform roll-off, obtain a smoother shaped waveform, optimize the d(n) coefficient, and obtain a better low PAPR effect. There are two main implementation methods: reserving idle PRBs and reserving duplicate PRBs.

Figure 1 illustrates a spectrum shaping method based on reserving idle PRBs. As shown in Figure 1, after the terminal (such as user equipment (User Equipment, UE)) data is scheduled, some free PRBs are reserved for it to put the filter roll-off side lobes into them. Compared with the method of placing UEs close to each other, reserving some free PRBs can reduce the roll-off amplitude requirements and cut-off frequency requirements of UE windowing, achieve a smoother drop at the roll-off point, and reduce sharp jitter, thus affecting PAPR. The characteristics are better improved, which can reduce the power backoff value, obtain higher actual transmit power, and obtain better performance improvement.

Figure 2 illustrates the spectrum shaping method based on repeated PRB. By repeating the content of the first PRB in the transmission data PRB and appending it to the end of the transmission data PRB, and repeating the content of the last PRB in the transmission data PRB and appending it to the front of the transmission PRB, the formation is as shown in Figure 2 PRB bandwidth type. Compared with the method shown in Figure 1, in this way, the correlation of reserved PRBs may be better than that of reserved free PRBs, so it may be able to achieve better performance improvement.

However, the indication method and usage effect of the extension PRB are uncertain. It is also unclear whether the extension PRB has been considered in the bandwidth of the currently scheduled PUSCH and PUCCH. Therefore, the indication method of the extension PRB needs to be clear. In the existing technology, PUSCH and PUCCH Whether the number of frequency domain RBs or REs includes extension PRBs also needs to be clarified. In scenarios such as extension PRB multiplexing, the number of frequency domain scheduling RBs or REs configured in the network needs to be given a clear determination solution to determine the frequency of FDSS. domain bandwidth.
