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 UE receives DCI: DL&UL Alloc, and receives DLPN 0 by using the time-frequency resource indicated in the downlink scheduling information in DCI: DL&UL Alloc, and sends ULPN 0 by using the time-frequency resource indicated in the uplink scheduling information in DCI: DL&UL Alloc.

In this way, in the scheduling process shown in FIG. 7, each time the UE is scheduled, the base station 10 needs to deliver DCI only once, and the UE needs to receive the DCI only once. However, actually, when sending the uplink information, the UE 11 needs to send only one bit of NEPN (Next PUD number). To schedule the one bit of NEPN, the base station 10 needs to send, for each UE, a total of 21 bits of downlink scheduling information including a channel frequency (6 bits), a transmission start time (4 bits), duration (6 bits), an MCS (4 bits), and an ULPN (1 bit), and signaling overheads are still relatively large.
