Abstract

The invention discloses a method, a system and a device for scheduling multiple subframes. The method for scheduling multiple subframes comprises the following steps of: issuing a continuous scheduling instruction for scheduling multiple subframes, a hybrid automatic retransmission process number and a scheduling configuration parameter corresponding to a first scheduled subframe to a terminal; and obtaining the hybrid automatic retransmission process number corresponding to a currently scheduled subframe according to the continuous scheduling instruction and the hybrid automatic retransmission process number corresponding to the first scheduled subframe, and transmitting data packets of corresponding hybrid automatic retransmission process number at the currently scheduled subframe by using the scheduling configuration parameter. Each scheduled subframe in the multiple subframe scheduling process carries one data packet and uses the scheduling configuration parameter. In the embodiment of the invention, by issuing the hybrid automatic retransmission process number and the continuous scheduling instruction of the currently scheduled subframe each time, the multiple subframe scheduling can be implemented, control signaling cost of the system is saved and spectral efficiency of the system is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field, and in particular to a multi-subframe scheduling method, system and device. Background technique [0002] In the existing third-generation system cooperation projects (3 rd Generation Partnership Project; 3GPP) Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (Evolved-UMTS Terrestrial Radio Access; E-UTRA) system supports Frequency Division Duplexing ; Abbreviation: FDD) and Time Division Duplexing (Time Division Duplexing; abbreviation: TDD) two modes. In the Long Term Evolution (LTE for short) system, the terminal receives downlink data and sends uplink data on the corresponding uplink and downlink resources according to the instructions of the physical downlink control channel (Physical Downlink Control Channel; PDCCH for short) issued by the base station. data. In the LTE FDD system, the maximum number of Hybrid Automatic Repeat Request (HA...
