Title: UPLINK INFORMATION SENDING METHOD AND APPARATUS, RECEIVING METHOD AND APPARATUS, AND COMMUNICATIONS SYSTEM
Abstract:
The present invention relates to an uplink information sending method and apparatus, a receiving method and apparatus, and a communications system. The uplink information sending method comprises: receiving downlink control information (DCI) and a time division duplexing (TDD) uplink-downlink configuration sent by a base station; determining, according to the TDD uplink-downlink configuration, that an uplink index (UL Index) domain or a downlink index allocation (DAI) domain exits in the DCI, the TDD uplink-downlink configuration comprising a configuration in a physical downlink control channel (PDCCH) or an uplink reference configuration; and on an uplink subframe corresponding to the determined existed UL Index domain, sending, according to the determined existed UL Index domain, uplink information corresponding to the DCI to the base station; or sending, according to the determined existed DAI domain, HARQ-ACK information corresponding to the determined existed DAI domain to the base station. The present invention can ensure that a function of the UL Index domain or the DAI domain can normally work, so that the overhead increase of downlink control signaling or uplink control signaling can be reduced, and the system capacity can be increased.
