Abstract
An uplink transmission method and an apparatus thereof are provided. The method includes that a terminal in an unlicensed spectrum determines a target indication parameter, where the target indication parameter is used for indicating a target transmission mode adopted when a terminal transmits uplink data. The method further includes that the terminal determines the target transmission mode according to the target indication parameter and transmits the uplink data to a base station in the unlicensed spectrum on the basis of the target transmission mode.
Claims12
An uplink transmission method, comprising:
- determining, by a terminal in an unlicensed spectrum, a target indication parameter, wherein the target indication parameter is used for indicating a target transmission mode adopted in response to determining that the terminal transmits uplink data;
- determining, by the terminal, the target transmission mode according to the target indication parameter;
- and
- transmitting, by the terminal, the uplink data to a base station in the unlicensed spectrum on the basis of the target transmission mode,
- wherein determining the target transmission mode according to the target indication parameter comprises:
- performing channel monitoring on a channel to be used, and determining a location where a target time unit is located in a time domain resource corresponding to the terminal transmitting the uplink data, wherein the target time unit is a starting time unit in response to monitoring that the channel is in an idle state;
- calculating a percentage of a total number of first time units to a total number of all time units comprised in the time domain resource, wherein the first time units are time units located before the target time unit in the time domain resource;
- and
- determining that the target transmission mode is a first transmission mode in response to determining that the percentage is less than or equal to a value of the target indication parameter, and determining that the target transmission mode is a second transmission mode in response to determining that the percentage is greater than the value of the target indication parameter.
