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

Uplink signal type Type 2 (Type 2)

For still another example, that N2=2 indicates that there are two occupied orthogonal frequency division multiplexing (OFDM) symbols in the uplink transmission time-frequency resource is used as an example. When two OFDM symbols in the uplink transmission time-frequency resource are occupied, the sent uplink signals are of the type 3 (Type 3), namely, the reference signal and the data signal.

Correspondingly, the foregoing may be expressed by using Table 6.

TABLE 6 A quantity of OFDM symbols per TTI NsymbUL = 2
