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(shuō)明書

In the uplink scheduling information of the UE, the uplink MCS and the information used to indicate duration for sending uplink information by the UE are carried in a system message broadcast by a base station, and then are sent to the UE, and the channel frequency at which the uplink information is sent and the data packet number of a PDU in which the uplink information is sent are carried in downlink data sent by the base station, and then are sent to the UE. The information used to indicate a time at which the UE sends the uplink information and downlink scheduling information are carried in DCI, and then sent to the UE.

Specifically, the information used to indicate a time at which the UE sends the uplink information includes an interval from a preset time point to the time at which the UE sends the uplink information. Referring to FIG. 12, FIG. 12 is schematic structural diagram of an embodiment of the DCI in this embodiment. The DCI includes R (reserved bit), DL number (quantity of UEs scheduled on a downlink), Feedback_Start_Indicator (preset time point), UL number (quantity of UEs scheduled on an uplink), DL & UL number (quantity of UEs scheduled on a downlink and an uplink at the same time), RACH number (quantity of UEs scheduled for RACH access), DL Allocation (downlink scheduling configuration), UL Allocation (uplink scheduling configuration), DL & UL Allocation (downlink and uplink scheduling configuration), RACH config (RACH scheduling configuration), and Padding (padding bit).
