摘要

An uplink information sending method and apparatus is provided. The method includes obtaining, by user equipment, downlink control information DCI and downlink data, the DCI carries a portion of uplink scheduling information of the user equipment, the uplink information is used to indicate whether the user equipment receives the downlink data correctly, the portion of the uplink scheduling information is specifically indication information excluding a specific parameter of the user equipment, and the specific parameter includes at least one of an uplink modulation and coding scheme MCS or information used to indicate duration for sending the uplink information. The method also includes sending, by the user equipment, the uplink information according to the portion of the uplink scheduling information and the specific parameter, where the specific parameter is a parameter preset in the user equipment or a parameter received by the user equipment from a system message.

說明書

In this embodiment, the specific parameter in the uplink scheduling information of the UE 11 is carried in the system message and then sent to the UE 11. In some possible implementation manners of the present embodiments, the specific parameter may not be sent to the UE 11 by being added to the system message, but be preset in the UE 11. For example, a communications protocol specifies specific parameters in uplink scheduling information of UEs at different coverage levels. After determining the coverage level of the UE 11, the UE 11 may determine a specific parameter of the UE 11 according to the communications protocol. Alternatively, a communications protocol specifies other parameters. After determining the coverage level of the UE 11, the UE 11 may determine a specific parameter of the UE 11 according to these parameters. If the specific parameter is preset in the UE 11 in step S1 in this embodiment, when the base station determines the uplink scheduling information of the UE 11, the uplink scheduling information does not include the specific parameter.
