A method performed by at least one processor in a user equipment (UE), the method including receiving, from a base station over a channel, a plurality of reference signals corresponding to a state of the channel. The method further including measuring a subset of the received plurality of reference signals. The method further including transmitting, to the base station within a first time interval, a channel status report corresponding to the measuring of the subset of the received plurality of reference signals and a prediction of one more reference signals received by the UE after the first time interval.

Method and apparatus for beam management using AI/ML

A method includes determining a least squares channel estimate (LSE) of a channel, removing a first Orthogonal cover code (OCC) sequence from the LSE thereby generating a first signal, determining an estimated timing offset of the first signal, adjusting a first timing of the LSE based on the estimated timing offset thereby generating a second signal with an adjusted timing, removing a second OCC sequence from the second signal thereby generating a third signal, determining a channel estimate of the channel based on the third signal, determining a noise power of a received signal, determining a signal power of the received signal, determining a signal to noise ratio (SNR) of the received signal based on the noise power and the signal power, adjusting a data rate of the channel based on the SNR, and transmitting an output signal based on an adjusted data rate of the channel.

Method, apparatus, and computer readable medium

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.
