Uplink transmission method, terminal, and network side device
摘要
說明書
a memory, configured to store an uplink transmission time-frequency resource allocated by a network side device to the terminal;
a processor, configured to: when the terminal needs to send an uplink signal, determine the to-be-transmitted uplink signal based on a quantity of orthogonal frequency division multiplexing (OFDM) symbols in the uplink transmission time-frequency resource stored in the memory; and
a transceiver, configured to send, to the network side device, the uplink signal determined by the processor.
During implementation by the terminal, a corresponding to-be-transmitted uplink signal is determined for a quantity of occupied OFDM symbols in a different uplink transmission time-frequency resource, and the uplink signal may be locally preconfigured by the terminal or delivered by the network side device to the terminal in different manners. Therefore, grant free transmission solutions are provided for different uplink transmission time-frequency resources, to ensure a grant free transmission effect and effectively improve communication performance.
According to another aspect, an embodiment provides a terminal, and the terminal includes:
a memory, configured to store an uplink transmission time-frequency resource allocated by a network side device and an uplink transmission indication, where the uplink transmission indication is used to indicate a time-frequency resource that is in the uplink transmission time-frequency resource and that can be used by a terminal to perform uplink transmission;
