Embodiment Construction

[0043] The inventor noticed in the course of the invention that, in addition to the difference in frame structure, other differences between FDD and TDD modes in LTE mainly exist in the difference in the duplex mode itself, that is, FDD uses continuous subframes to work, while TDD uplink or Downlink subframes are discontinuous in time, which leads to some differences in uplink and downlink scheduling and retransmission timing and control processes. However, other basic transmission technologies are exactly the same between FDD and TDD, which is also a further step for the two. Convergence provides conditions, that is, FDD and TDD can be provided in the communication system at the same time. The specific implementation manner of the present invention will be described below with reference to the accompanying drawings.

Abstract

The invention discloses a signal transmitting method and signal transmitting equipment. The method comprises the following steps of: determining the duplex mode of user equipment; and performing signal transmission on the user equipment by using a network side according to the duplex mode of the user equipment in a time division mode. Through the method and the equipment, access support of network side equipment for user equipment of other duplex mode types is increased on the basis of ensuring the performance of a system of duplex mode type, which is a communication scheme capable of providing a communication service of multi-duplex mode types.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a signal transmission method and equipment. Background technique [0002] For a cellular mobile communication system, the duplex mode is the multiplexing mode of the uplink and downlink; and for the mobile communication device (base station or UE), the duplex mode is the multiplexing mode of the sending and receiving links. TDD (Time Division Duplex, Time Division Duplex) and FDD (Frequency Division Duplex, Frequency Division Duplex) are two basic duplex methods for wireless communication transmission, and both TDD and Long Term Evolution are supported in the LTE (Long Term Evolution) system FDD mode. The TDD mode means that the uplink and downlink use different time intervals for signal transmission; the FDD mode means that the uplink and downlink use different working frequency bands for uplink and downlink signal transmission. Duplex mode can refer to figure 1 an...
