Claims20
An information transmission method, applied to a network device and comprising:
- sending target information on at least one sub symbol of a first orthogonal frequency division multiplexing (OFDM) symbol, wherein
- the first OFDM symbol comprises at least two sub symbols, a time-domain resource of the at least one sub symbol is a part or all of a target time-domain resource, the target time-domain resource is a time-domain resource that is used to transmit a cyclic prefix before the first OFDM symbol is divided into the at least two sub symbols, and a cyclic prefix time of the first OFDM symbol is greater than a cyclic prefix time of other OFDM symbols in the same frame structure;
- and
- the target information comprises at least one of following:
- at least a part of content of a specific reference signal;
- at least a part of content of a channel;
- or
- information that corresponds to an available signal region before the first OFDM symbol is divided into the at least two sub symbols.
A network device, comprising a memory, a processor, and a computer program that is stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, causes the network device to perform:
- sending target information on at least one sub symbol of a first orthogonal frequency division multiplexing (OFDM) symbol, wherein
- the first OFDM symbol comprises at least two sub symbols, a time-domain resource of the at least one sub symbol is a part or all of a target time-domain resource, the target time-domain resource is a time-domain resource that is used to transmit a cyclic prefix before the first OFDM symbol is divided into the at least two sub symbols, and a cyclic prefix time of the first OFDM symbol is greater than a cyclic prefix time of other OFDM symbols in the same frame structure;
- and
- the target information comprises at least one of following:
- at least a part of content of a specific reference signal;
- at least a part of content of a channel;
- or
- information that corresponds to an available signal region before the first OFDM symbol is divided into the at least two sub symbols.
A terminal, comprising a memory, a processor, and a computer program that is stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, causes the terminal to perform:
- receiving target information sent by a network device on at least one sub symbol of a first orthogonal frequency division multiplexing (OFDM) symbol, wherein
- the first OFDM symbol comprises at least two sub symbols, a time-domain resource of the at least one sub symbol is a part or all of a target time-domain resource, the target time-domain resource is a time-domain resource that is used to transmit a cyclic prefix before the first OFDM symbol is divided into the at least two sub symbols, and a cyclic prefix time of the first OFDM symbol is greater than a cyclic prefix time of other OFDM symbols in the same frame structure;
- and
- the target information comprises at least one of following:
- at least a part of content of a specific reference signal;
- at least a part of content of a channel;
- or
- information that corresponds to an available signal region before the first OFDM symbol is divided into the at least two sub symbols.
