AI Technical Summary

Problems solved by technology

However, when the base station changes the attribute of the flexible subframe, the user equipment cannot obtain the current flexible subframe attribute corresponding to the received data, so that the user equipment cannot process the received data according to the current flexible subframe attribute corresponding to the data. Ultimately, the base station and user equipment cannot communicate normally

Abstract

An embodiment of the invention discloses a method, a device and a system for information transmission and subscriber equipment. The method for information transmission includes that flexible subframe attribute information is determined by a base station, and the determined flexible subframe attribute is transmitted to the subscriber equipment via a PMCH (physical multicast channel) by the base station. As the changed flexible subframe attribute information is transmitted to the subscriber equipment via the PMCH by the base station, the data transmission between the subscriber equipment and the base station can be achieved according to the flexible subframe attribute, and the resource consumption and the complexity of the information transmission can be reduced. The method, the device, the system for information transmission and the subscriber equipment are applicable to the communication system field.

Description

technical field [0001] The present invention relates to the field of communication systems, in particular to an information transmission method, device, system and user equipment. Background technique [0002] In the mobile communication system, there are two basic duplex modes, Time Division Duplex (TDD, Time Division Duplex) and Frequency Division Duplex (FDD, Frequency Division Duplex). The TDD mode means that the uplink (UL, Uplink) and the downlink (DL, Downlink) use the same frequency band, and the uplink and downlink signals are transmitted at different time intervals. [0003] In the LTE (Long Term Evolution) TDD system, each radio frame has a length of 10 ms and includes 10 subframes, and each subframe has a length of 1 ms. According to different configurations, the uplink and downlink respectively use different subframes of the same frequency for data transmission. In order to adapt to different application scenarios, the LTE TDD system can change the uplink-down...
