Uplink transmission method, terminal, and network side device
摘要
說明書
During implementation of this embodiment, because the network side device preconfigures the uplink transmission time-frequency resource and the uplink transmission indication for the terminal, when the terminal needs to send the uplink signal, the terminal may perform, based on the quantity of OFDM symbols in the uplink transmission time-frequency resource possessed by the terminal, uplink transmission on the uplink transmission time-frequency resource carried in the uplink transmission indication, so that transmission is more orderly; and the network side device can also perform detection on a corresponding time-frequency resource, thereby improving transmission efficiency of the uplink signal.
In an implementation, the uplink transmission indication carries an ID of an OFDM symbol and an ID of a sub-and that can be used by the terminal to perform uplink transmission, and the terminal transmits the uplink signal on the uplink time-frequency resource corresponding to the ID of the OFDM symbol and the ID of the sub-and.
In another implementation, the uplink transmission indication carries a quantity of sub-band intervals and a quantity of sub-bands in the uplink transmission time-frequency resource, and therefore, the terminal determines, in the uplink transmission time-frequency resource based on the quantity of sub-bands, the quantity of sub-band intervals, and the quantity of OFDM symbols in the uplink transmission time-frequency resource, the ID of the OFDM symbol and the ID of the sub-and that can be used by the terminal to perform uplink transmission, and the terminal transmits the uplink signal on the uplink time-frequency resource corresponding to the ID of the OFDM symbol and the ID of the sub-and.
In an implementation, the ID of the OFDM symbol and the ID of the sub-band are determined by using the following formula:
