Communication method, communication device, electronic device, and computer readable storage medium

A communication method, comprising:

• receiving modulated transmission information from a transmitter, wherein the modulated transmission information comprises constellation symbol information and indication information;
• obtaining, based on an index modulation mode, the indication information from the modulated transmission information, according to a location of a resource occupied by the constellation symbol information in a transmission block,
• the index modulation mode comprises:
• an occupancy rule for the location of the resource in the transmission block, wherein the occupancy rule for the location of the resource in the transmission block provides a number of resources randomly selected for transmission of the constellation symbol information from a total number of resources contained in at least one transmission block;
• and
• determining, in response to determining that a number of bits of the indication information is greater than a number of bits of the constellation symbol information, that a first portion of the bits of the indication information corresponds to a retransmission content of the constellation symbol information, and performing a check on the location of the resource using a second portion of the bits of the indication information.

An electronic device, comprising a memory, a processor and a computer program stored on the memory and runnable on the processor, wherein the processor, when executing the computer program, implements following acts:

• performing, based on an index modulation mode, index modulation on indication information to be sent, by a location of a resource occupied by constellation symbol information in a transmission block, to generate modulated transmission information,
• wherein the modulated transmission information comprises the constellation symbol information and the indication information,
• the index modulation mode comprises:
• an occupancy rule for the location of the resource in the transmission block,
• wherein the occupancy rule for the location of the resource in the transmission block provides a number of resources randomly selected for transmission of the constellation symbol information from a total number of resources contained in at least one transmission block;
• and
• performing, in response to determining that a number of bits of the indication information is greater than a number of bits of the constellation symbol information, retransmission on the constellation symbol information using a first portion of the bits of the indication information, and carrying a check bit for the location of the resource using a second portion of the bits of the indication information.
