Definitions
- the embodiments of the present application relate to the field of communication technologies, and in particular, to a communication method, a resource allocation method, and a device.
- Spectrum resources are divided into licensed (Licensed spectrum) and unlicensed (spectrum) spectrum.
- the licensed spectrum can be used by some institutions or operators.
- Unlicensed spectrum is shared spectrum and can be used by different operators / institutions. Therefore, in order to use the unlicensed spectrum fairly, the terminal and the access network device need to perform a listen-before-talk (LBT) channel access process before sending data. If the LBT channel access process is not completed, the terminal and the access network device cannot use the unlicensed spectrum to send data. The LBT channel access process is completed, and the terminal and access network equipment can use this unlicensed spectrum to send data.
- LBT listen-before-talk
- the current LBT channel access process includes: energy detection based on a fixed duration and energy detection based on a backoff mechanism. For energy detection based on a fixed duration, the terminal or the access network equipment determines that the detected signal energy at the fixed duration is lower than a preset threshold, the channel is considered to be idle, otherwise the terminal or the access network equipment determines that the channel is busy. For the capability detection based on the fallback mechanism, the terminal and the access network device randomly select a value A from a range window. When detecting at least A idle energy detection based on a fixed duration, the terminal or the access network device determines the channel. idle. When the channel is free, data can be sent; otherwise, data cannot be sent.
- the access network device In the prior art, no matter whether the terminal performs LBT successfully, if the access network device cannot resolve the data sent by the terminal, the access network device sends a retransmission instruction to the terminal to instruct the terminal to resend the data. However, the access network equipment is not sure what causes the terminal to fail to send data. In addition, the prior art does not record how the terminal uses the transmission resources in the unlicensed spectrum to send data to another terminal on the side link.
