Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may be configured to transmit data to a network device using an unencoded signal that includes parameters for updating a local data model. The UE may receive a radio network temporary identifier (RNTI) to decode a resource allocation message that schedules uplink resources for the transmission of the parameters, where the RNTI may be a dedicated RNTI that is different from other RNTIs received by the UE. The UE may identify allocated resources as scheduled by the resource allocation message, and may apply analog modulation and pre-equalization parameters to a data block to form an unencoded uplink transmission that includes the model parameters. The UE may transmit the unencoded uplink message in accordance with an over-the-air computation procedure.

This application provides a communication method and apparatus, and relates to the field of communication technologies. A terminal receives first indication information that is sent by a network device and that indicates a time-frequency resource and an MCS of first data, and determines a first time-frequency resource carrying the first data, a second time-frequency resource carrying second data, and an MCS of the second data. The time-frequency resource includes the first time-frequency resource and the second time-frequency resource. In the method, if there are two pieces of data, the terminal may determine time-frequency resources and MCSs of the two pieces of data, to meet different data requirements and flexibly perform data transmission.
