Random access method and apparatus, and device

A random access apparatus, the random access apparatus comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing program instructions for execution by the at least one processor to:
• obtain a first random access preamble length and a second random access preamble length, wherein the first random access preamble length is a duration of a first random access preamble sent by a first terminal device, the second random access preamble length is a duration of a second random access preamble sent by a second terminal device, and a value of a delay compensation performed by a network device when receiving the first random access preamble is different from a value of a delay compensation performed by the network device when receiving the second random access preamble;
• determine a first random access parameter of the first terminal device and a second random access parameter of the second terminal device based on the first random access preamble length and the second random access preamble length, wherein there is an overlapping part, in time domain, between the first random access preamble indicated by the first random access parameter and the second random access preamble indicated by the second random access parameter;
• and
• send the first random access parameter to the first terminal device, and send the second random access parameter to the second terminal device.

A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium stores program instructions for execution by at least one processor to:

• obtain a first random access preamble length and a second random access preamble length, wherein the first random access preamble length is a duration of a first random access preamble sent by a first terminal device, the second random access preamble length is a duration of a second random access preamble sent by a second terminal device, and a value of a delay compensation performed by a network device when receiving the first random access preamble is different from a value of a delay compensation performed by the network device when receiving the second random access preamble;
• determine a first random access parameter of the first terminal device and a second random access parameter of the second terminal device based on the first random access preamble length and the second random access preamble length, wherein there is an overlapping part, in time domain, between the first random access preamble indicated by the first random access parameter and the second random access preamble indicated by the second random access parameter;
• and
• send the first random access parameter to the first terminal device, and send the second random access parameter to the second terminal device.
