Problems solved by technology

[0005] It can be seen that in order to meet the above requirements, for the TDD communication system, at least the first two subframes must have the capability of downlink transmission, which will greatly limit the flexible frame structure of the fifth-generation mobile phone mobile communication standard (5G) ; Moreover, the difference in the relative position of PSS / SSS enables the terminal to identify whether the system is TDD or FDD, that is, the duplex mode is non-transparent to the terminal, which will not be conducive to the integrated development of TDD and FDD at a certain level

Abstract

Embodiments of the present invention provide a signal transmission method, device, and base station, wherein the transmission method includes: transmitting the master synchronization signal at the first predetermined transmission position of each frame in the first communication system, the first predetermined transmission position The same as the position where the primary synchronization signal is transmitted in the second communication system; the secondary synchronization signal is transmitted at the second predetermined transmission position of each frame in the first communication system, and the second predetermined transmission position is the same as the secondary synchronization signal transmitted in the second communication system The positions are the same, wherein, the first communication system is one of the time division duplex TDD communication system and the frequency division duplex FDD communication system, and the second communication system is one of the time division duplex TDD communication system and the frequency division duplex FDD communication system Another, the embodiment of the present invention can realize the transparency of the duplex mode to the terminal while ensuring the flexibility of the standard frame structure of the fifth generation mobile phone mobile communication, which is beneficial to the integrated development of time division duplex and frequency division duplex.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a signal transmission method, device and base station. Background technique [0002] The Long Term Evolution (LTE, Long Term Evolution) system respectively defines Frequency Division Duplex (FDD, Frequency Division Dual) and Time Division Duplex (TDD, Time Division Duplexing) as follows. [0003] Wherein, FDD means that the downlink time slots are transmitted on the downlink carrier of the paired FDD spectrum, and the uplink time slots are transmitted on the uplink carrier, and TDD means that the uplink and downlink time slots are transmitted on the same TDD carrier by time division. Among them, in the frame structure of FDD and TDD, the duration of a frame is 10 milliseconds, and a frame includes 10 subframes, and each subframe is a transmission time interval with a duration of 1 millisecond, and a subframe includes 2 time slots, each Each time slot has a duration of ...
