Data transmission method and apparatus

A frequency hopping transmission method, comprising:

• obtaining a first sequence, wherein the first sequence comprises Q elements, and the Q elements correspond to Q different frequencies, where Q is a positive integer greater than 1;
• determining a first element in the first sequence;
• and
• performing data transmission with a first terminal device in one frequency hopping cycle based on a frequency corresponding to an element in the first sequence, wherein the one frequency hopping cycle comprises M frequency hopping moments,
• a first frequency corresponding to the first terminal device at a first frequency hopping moment of the M frequency hopping moments is a frequency corresponding to the first element,
• a second frequency corresponding to the first terminal device at an ith frequency hopping moment of the M frequency hopping moments is a frequency corresponding to a second element obtained by cyclically moving from the first element in a left direction or a right direction for i−1 times according to a specified rule, the left direction being opposite from the right direction, where i is a positive integer from 2 to M, and M is a positive integer greater than or equal to 2.

A communication apparatus, comprising at least one processor and at least one memory, wherein the at least one memory is configured to store non-transitory instructions, and in response to the at least one processor being configured to execute the non-transitory instructions thereby causing the communication apparatus to:

• obtain a first sequence, wherein the first sequence comprises Q elements, and the Q elements correspond to Q different frequencies, where Q is a positive integer greater than 1;
• determine a first element in the first sequence;
• and
• perform data transmission with a network device in one frequency hopping cycle based on a frequency corresponding to an element in the first sequence,
• wherein the one frequency hopping cycle comprises M frequency hopping moments,
• a first frequency corresponding to the apparatus at a first frequency hopping moment of the M frequency hopping moments is a frequency corresponding to the first element,
• a second frequency corresponding to the apparatus at an ith frequency hopping moment of the M frequency hopping moments is a frequency corresponding to an element obtained by cyclically moving from the first element in a left direction or a right direction for i−1 times according to a specified rule, the left direction being opposite from the right direction, where i is a positive integer from 2 to M, and M is a positive integer greater than or equal to 2.
