Information transmission method, communication apparatus, storage medium, chip, and program product

A communication apparatus, comprising:

• a processor;
• and
• a communication interface to perform information exchange with another communication device, wherein when program instructions are executed by the processor, the communication device is enabled to perform:
• receiving a trigger-based frame from a second device, wherein the trigger-based frame comprises distributed resource unit indication information indicating a distributed resource unit allocated to the communication apparatus;
• determining one or more distributed resource blocks based on the distributed resource unit indication information, wherein each of the one or more distributed resource blocks comprises N1 data subcarriers and N2 pilot subcarriers, an absolute value of an index difference between every two data subcarriers of N3 data subcarriers in the NI data subcarriers is greater than or equal to 4, N1, N2, and N3 are all positive integers, and 1≤N2<N3, and wherein N1=N3=24, or N1=N3=48, or N1=102 and N3=96, or N1=234 and N3=192, or N1=468 and N3=384, or N1=980 and N3=768;
• and
• sending a response to the trigger-based frame to the second device based on the one or more distributed resource blocks.

A chip, comprising:

• a communication interface;
• and
• a processing circuit configured to perform:
• receiving a trigger-based frame from a second device, wherein the trigger-based frame comprises distributed resource unit indication information indicating a distributed resource unit allocated to the chip;
• determining one or more distributed resource blocks based on the distributed resource unit indication information, wherein each of the one or more distributed resource blocks comprises N1 data subcarriers and N2 pilot subcarriers, an absolute value of an index difference between every two data subcarriers of N3 data subcarriers in the NI data subcarriers is greater than or equal to 4, N1, N2, and N3 are all positive integers, and 1≤N2<N3, and wherein N1=N3=24, or N1=N3=48, or N1=102 and N3=96, or N1=234 and N3=192, or N1=468 and N3=384, or N1=980 and N3=768;
• and
• outputting a response to the trigger-based frame to the second device based on the one or more distributed resource blocks.
