There is a specific correlation between an uplink channel and a downlink channel, and therefore the control parameter, of the downlink data, configured by a base station for the user equipment may reflect a current coverage status of the user equipment. Therefore, a rule may be set for mapping the control parameter of the downlink data onto the duration information of the uplink information, and the duration information of the uplink information may be directly obtained according to the mapping of the control parameter of the downlink data. No additional transmission is required.
For example, the duration information of the uplink information may be a quantity of retransmission times of the uplink information, the control parameter of the downlink data is the quantity of retransmission times of the downlink data, and the mapping rule is: Quantity of retransmission times of uplink information=Quantity of retransmission times of downlink data×4
In the mapping rule, the user equipment first receives downlink scheduling DCI, obtains scheduling information of the downlink data from the downlink scheduling DCI, and parses out the control parameter from the scheduling information. For example, if the quantity of retransmission times of the downlink data may be set to 2 in the control parameter, the quantity of retransmission times of the uplink information is 8 according to the mapping rule.
