Abstract
Disclosed are an access and transmission method, and a network-side device, a terminal and a storage medium, which are used for solving the problem in the related art of a collision in preamble parts. In the embodiments of the present application, pseudo-random information is added to preamble parts, and the preamble parts and data parts are sent by using resources configured on a network side, such that the preamble parts of different terminals can be made to be as different as possible by using the pseudo-random information, thereby avoiding the problem of multiple collisions being caused due to preamble parts of the terminals being the same.
Claims20
An access and transmission method, comprising:
- receiving resource configuration information sent by a network-side device;
- adding pseudo-random information to preamble part information, to obtain preamble information to be processed;
- generating a preamble code of the preamble information to be processed;
- and
- sending the preamble code and a data code of data part information on a basis of the resource configuration information.
An access and transmission method, comprising:
- sending resource configuration information to a terminal device, wherein the resource configuration information is used by the terminal device to send a preamble code and a data code of data part information, wherein the preamble code is generated by the terminal device on a basis of preamble information to be processed, and the preamble information to be processed comprises pseudo-random information and preamble part information of the terminal device;
- and
- decoding, in response to the preamble code being detected, the data code on a basis of the preamble code.
A terminal device, comprising:
- a processor, a memory and a transceiver;
- wherein
- the memory is configured to store a computer program;
- the transceiver is configured to receive and send data under control of the processor;
- and
- the processor is configured to read the computer program in the memory to:
- receive resource configuration information sent by a network-side device through the transceiver;
- add pseudo-random information to preamble part information, to obtain preamble information to be processed;
- generate a preamble code of the preamble information to be processed;
- and
- send the preamble code and a data code of data part information on a basis of the resource configuration information.
