Transmission control method and apparatus

A first device comprising:

• a processor;
• and
• a transmitter;
• wherein the processor is configured to:
• generate transmission control information, wherein the transmission control information comprises resource indication information, a compression indication, and a first indication, the resource indication information indicates a transmission resource allocated by the first device to a second device, the transmission resource comprises at least two symbols, the compression indication indicates a numerology of one or more specific symbols in the transmission resource, the one or more specific symbols comprises at least an end symbol or a second type of symbol, the end symbol is the last symbol in the transmission resource, the second type of symbol is a symbol in the transmission resource useable for transmitting only a demodulation reference signal (DMRS) or a long training field, the second type of symbol comprises at least one symbol, and the first indication indicates a numerology of symbols in the transmission resource other than the one or more specific symbols;
• and
• wherein the transmitter is configured to:
• send the transmission control information to the second device;
• wherein the compression indication indicates a numerology of the end symbol, and the numerology of the end symbol comprises a subcarrier spacing corresponding to the end symbol, and the subcarrier spacing corresponding to the end symbol is an integer multiple of a subcarrier spacing corresponding to a first type of symbol.

A second device comprising:

• a receiver;
• and
• a processor;
• wherein the receiver is configured to:
• receive transmission control information from a first device, wherein the transmission control information comprises resource indication information, a compression indication, and a first indication, the resource indication information indicates a transmission resource allocated by the first device to the second device, the transmission resource comprises at least two symbols, the compression indication indicates a numerology of one or more specific symbols in the transmission resource, the one or more specific symbols comprises at least an end symbol or a second type of symbol, the end symbol is the last symbol in the transmission resource, the second type of symbol is a symbol in the transmission resource useable for transmitting only a demodulation reference signal (DMRS) or a long training field, the second type of symbol comprises at least one symbol, and the first indication indicates a numerology of symbols in the transmission resource other than the one or more specific symbols;
• and
• wherein the processor is configured to:
• determine the transmission resource based on the resource indication information,
• determine the numerology of the one or more specific symbols in the transmission resource based on the compression indication, and
• determine the numerology of the symbols in the transmission resource other than the one or more specific symbols based on the first indication;
• and
• the processor or the receiver includes one of the following configurations:
• wherein the one or more specific symbols includes only the end symbol, and the compression indication indicates a numerology of the end symbol;
• or
• wherein the one or more specific symbols comprises the end symbol and the second type of symbol, and the compression indication indicates a numerology of the end symbol and a numerology of the second type of symbol.
