摘要

This application provides an uplink transmission method, a terminal, and a network side device. The method includes: storing, by a terminal, an uplink transmission time-frequency resource allocated by a network side device; when the terminal needs to send an uplink signal, determining the to-be-transmitted uplink signal based on a quantity of orthogonal frequency division multiplexing (OFDM) symbols in the uplink transmission time-frequency resource; and sending, by the terminal, the uplink signal to the network side device. During implementation of the uplink transmission method provided in this application, grant free transmission solutions are provided for different uplink transmission time-frequency resources, to effectively improve communication performance.

說明書

That the terminal determines the to-be-transmitted uplink signal by using the locally preconfigured correspondence between a quantity of OFDM symbols (subframe format) and an uplink signal includes the following at least four cases:

Manner 1: The terminal locally preconfigures a plurality of types of uplink signals, and one type of uplink signal is corresponding to one subframe format.

Manner 2: The terminal locally preconfigures a plurality of types of uplink signals, and one type of uplink signal is corresponding to one type of subframe format.

Manner 3: The terminal locally preconfigures one type of uplink signal, and the type of uplink signal is corresponding to one subframe format.

Manner 4: The terminal locally preconfigures one type of uplink signal, and the type of uplink signal is corresponding to one type of subframe format. That the terminal determines a transmission type by using the uplink transmission indication delivered by the network side device to the terminal includes the following at least four cases:

Manner 1: The network side device delivers one uplink transmission indication to the terminal, the uplink transmission indication carries at least one type of uplink signal, and one type of uplink signal is corresponding to one subframe format.

Manner 2: The network side device delivers one uplink transmission indication to the terminal, the uplink transmission indication carries at least one type of uplink signal, and one type of uplink signal is corresponding to one type of subframe format.
