Abstract: A reference signal indication method includes receiving a plurality of reference signals, and sending at least one codeword on a first time-frequency resource. The at least one codeword includes a first codeword. The first codeword corresponds to a first reference signal in N reference signals of the plurality of reference signals. The first reference signal is a selected reference signal. The N reference signals are a subset of the plurality of reference signals, and N is a positive integer.

Abstract: In a method for determining a resource of an asynchronous physical uplink shared channel PUSCH, user equipment (UE) receives time domain resource configuration information and frequency domain resource configuration information from a network device. The UE sets, based on the time domain resource configuration information, a time domain position of a first hop of a first PUSCH and a time domain position of a second hop of the first PUSCH to be inconsecutive in the time domain. The UE then determines a frequency domain position of the first hop of the first PUSCH and a frequency domain position of the second hop of the first PUSCH based on the frequency domain resource configuration information.

Abstract: This disclosure provides a communication method and apparatus. An apparatus obtains an ith piece of first information that indicates an ith local model of each of K subnodes and i is a positive integer, and determines an ith federated learning model of a kth subnode based on the ith piece of first information and a type of the ith federated learning model of the kth subnode, where k is any positive integer from 1 to K. When i is greater than 1, the type of the ith federated learning model of the kth subnode is determined based on a type or performance of an (i−1)th federated learning model of the kth subnode. The apparatus sends an ith piece of second information, where the ith piece of second information indicates an ith federated learning model of each of the K subnodes.
