Abstract: The disclosure includes a communication method and a communication apparatus. The communication method includes the communication apparatus determining to use a reserved tone, determining a reference signal pattern and a tone reservation (TR) pattern, and performing data transmission based on the reference signal pattern and the TR pattern. The reference signal pattern includes a first reference signal sub-pattern and a second reference signal sub-pattern, and the second reference signal sub-pattern is an offset of the first reference signal sub-pattern in time domain and/or frequency domain. According to the method, a reference signal pattern having a plurality of different sub-patterns may be provided, so that reference signals are unevenly distributed on a bandwidth. In this way, even if a reference signal density is high, a large secondary peak value of a kernel time domain signal generated on a subcarrier used as a reserved tone can be avoided, thereby improving peak-to-average power ratio (PAPR) suppression performance.

Abstract: This application relates to communication methods and communication apparatuses. In an example method, a terminal device or a chip in the terminal device obtains first information. The first information is used to determine an access range corresponding to a first signal. In response to determining that the terminal device is located in the access range after a first moment, the terminal device or the chip in the terminal device sends a first random access preamble. The first random access preamble is associated with the first signal.

The method includes: A first device sends, to a second device, first data modulated by using a first quadrature amplitude modulation codebook. The second device receives, from the first device, the first data modulated by using the first quadrature amplitude modulation codebook.

The second data is a part or all of the first data, and the first quadrature amplitude modulation codebook is different from the second quadrature amplitude modulation codebook. The second device receives, from the first device, the second data modulated by using the second quadrature amplitude modulation codebook, and jointly decodes the first data and the second data.
