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

The base station specifies a preset time point Feedback_Start_Indicator for all UEs in UL number and DL & UL number in the DCI. Because the base station performs uplink scheduling and downlink scheduling at the same time for the UE, scheduling information of the UE is added to DL & UL Allocation in the DCI. The time interval in the time information of the UE may be added to DL&UL Allocation. As shown in FIG. 13, FIG. 13 is a schematic structural diagram of an embodiment of DL & UL Allocation in the DCI shown in FIG. 12. DL & UL Allocation includes RNTI, DL_CH_ID, DL_MCS, DL_Start Indicator, DL_Duration, DLPN, UL_CH_ID, Feedback offset (time interval), and R.

Specifically, the preset time point is the Nth frame that is after the UE receives the DCI. N is an integer greater than 0. Feedback offset may be used to instruct the UE to send the uplink information in the xth timeslot of the Nth frame that is after the DCI is received. X is an integer greater than or equal to 0.

Alternatively, if DL & UL Allocation has only the downlink scheduling information and the time interval in the time information of the UE, the downlink scheduling information and the time interval in the time information of the UE may be added not to DL&UL Allocation in the DCI, but to DL Allocation in the DCI. As shown in FIG. 14, FIG. 14 is a schematic structural diagram of an embodiment of DL Allocation in the DCI shown in FIG. 12. DL Allocation includes RNTI, CH_ID, MCS, Start Indicator, Duration, DLPN, Feedback offset, and R.

The following describes a third example.
