Abstract
Provided in the embodiments of the present application are an information transmission method and apparatus, and a first communication node and a second communication node. The method comprises: receiving an extended preamble sequence based on a selected extended code and transmitted by a second communication node; determining a target extended code based on the extended preamble sequence, where the target extended code is an extended code selected by a single second communication node in an extended code set; and transmitting indication information of the target extended code.
Claims20
An information transmission method, applied to a first communication node, the method comprising:
- receiving an extended preamble sequence based on a selected extended code and transmitted by a second communication node;
- determining a target extended code based on the extended preamble sequence, wherein the target extended code is an extended code selected by a single second communication node in an extended code set;
- and
- transmitting indication information of the target extended code;
- wherein
- the extended preamble sequence includes:
- an extended preamble sequence, obtained by each element of a preamble sequence being multiplied by the selected extended code;
- or, an extended preamble sequence, obtained by a preamble sequence being multiplied by each element of the selected extended code.
An information transmission method, applied to a second communication node, the method comprising:
- selecting an extended code from an extended code set;
- extending a preamble sequence based on the extended code that is selected, so as to obtain an extended preamble sequence;
- and
- transmitting the extended preamble sequence;
- wherein
- the extended preamble sequence includes:
- an extended preamble sequence, obtained by each element of the preamble sequence being multiplied by the extended code that is selected;
- or, an extended preamble sequence, obtained by the preamble sequence being multiplied by each element of the extended code that is selected.
A first communication node, comprising:
- one or more processors;
- a storage means, configured to store one or more programs;
- when the one or more programs are executed by the one or more processors, such that the one or more processors implement steps of:
- receiving an extended preamble sequence based on a selected extended code and transmitted by a second communication node;
- determining a target extended code based on the extended preamble sequence, wherein the target extended code is an extended code selected by a single second communication node in an extended code set;
- and
- transmitting indication information of the target extended code;
- wherein
- the extended preamble sequence includes:
- an extended preamble sequence, obtained by each element of a preamble sequence being multiplied by the selected extended code;
- or, an extended preamble sequence, obtained by a preamble sequence being multiplied by each element of the selected extended code.
