Abstract

The embodiment of the invention provides a method, a device and a system for sending, receiving and transmitting business data, belonging to the field of communication. The method for sending the business data comprises the steps of sending the business data in the determined transmission time interval and notifying a terminal of the transmission time interval for sending the follow-up business data in the current scheduling cycle. The method for receiving the business data comprises the steps of receiving the business data and receiving the follow-up business data when knowing the follow-up business data sent by a base station in the current scheduling cycle. The embodiment of the invention further provides the device for sending and receiving the business data and the system for transmitting the business data. In the embodiment of the invention, the base station can determine the transmission time interval for sending the business data in the scheduling cycle, thereby reducing the data transmission time delay and avoiding the data loss. Furthermore, the terminal can timely know information of the transmission time interface for receiving the business data, thereby shortening themonitoring time and saving the energy consumption of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for sending, receiving and transmitting service data. Background technique [0002] Multicast Multicast Service (MBMS, Multimedia Broadcast Multicast Service) is one of the important contents of 3GPP service development. MBMS mainly means that the network side sends the same multimedia data to multiple receivers in the network at the same time. Compared with single-user transmission, MBMS greatly saves air interface resources. [0003] In the prior art, there are two transmission modes of MBMS data: one is a multi-cell mode; the other is a single-cell mode. When using single-cell mode to transmit MBMS data, the evolved base station (eNB, evovled NodeB) uses semi-static scheduling to send MBMS data, and schedules MBMS data once in each semi-static scheduling period, that is, the eNB shares the channel through the physical downlink ( PDSCH, Physical D...
