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 transmission method and equipment, comprising: determining the duplex mode of the user equipment; the network side adopts a time-division method to perform signal transmission with the user equipment according to the duplex mode of the user equipment. The present invention ensures that on the basis of the system performance of one duplex system type, the access support of network side equipment to user equipment of other duplex system types is added, and it is a communication system capable of providing multi-duplex system type communication services Program.

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 FDD are supported in the LTE (Long Term Evolution, Long Term Evolution) system model. 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 ...
