Abstract
A network device includes a processor, and receiver circuitry receiving a signal from a plurality of terminal devices, over a physical uplink control channel (PUCCH) format 1 (FMT1). The processor is coupled to the receiver circuitry, and performs processing on the received signal to obtain decoded data and signal-to-noise ratios (SNRs) corresponding to the plurality of terminal devices, and utilizes the decoded data and the SNRs for handling further communications with the plurality of terminal devices. In the processing, the processor obtains, from the received signal, a time domain sequence by performing a transform from a frequency domain into a time domain. The processor extracts, from the time domain sequence, noise blocks and one or more data blocks corresponding to each terminal device among the plurality of terminal devices. The processor further estimates a current noise power value based on the extracted noise blocks and a previous noise power value.
