Problems solved by technology

When the data rate of the service received by the user terminal is relatively high, such as receiving multiple time slots continuously, the reduction in the processing time of the data part will increase the requirements for the receiver capability of the user terminal, thereby increasing the cost

Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] The embodiments of the present invention all take the TD-SCDMA system as an example to describe the frame structure and its receiving method and device. Those skilled in the art will know that the TD-SCDMA here is only an example. The frame structure of the present invention and its receiving method and device It can be extended to any kind of communication system.

[0047] Figure 4 An embodiment of the frame structure for TD-SCDMA of the present invention is shown. See Figure 4 , taking the time slot 403 as an example, the time slot 403 is divided into a reference symbol part (PreAmble) 410 and a data part (Data Part) 408, and the reference symbol part (PreAmble) 410 is basically composed of a cyclic prefix (CP) 416 and a reference symbol Code (PA Code) 415 constitutes. In the present invention, the reference symbol part 410 is located beh...

Abstract

The invention discloses a frame structure in a communications system and a frame receiving mode and a device thereof. Under the premise of keeping the spectrum effectiveness unchangeable, the receptivity of a terminal is improved, and the complexity of a terminal receiver is lowered. The technical proposal is as follows: a time slot structure of the frame structure is composed of a reference markpart and a data part, the reference mark is composed of a circulation prefix and a reference mark basic code, wherein the reference mark part is positioned at the rear end of the time slot, the data part is positioned at the front of the reference mark. The invention is applied to the field of mobile communication.

Description

technical field [0001] The present invention relates to a frame structure and a frame receiving method and device in a communication system, in particular to a frame structure in which complete reference symbols are distributed at both ends of a time slot and a frame receiving method and device in a communication system. Background technique [0002] In traditional broadcasting systems, such as analog TV broadcasting, in order to expand coverage, adjacent transmitting stations use different frequencies to avoid mutual interference, and the same frequency must be reused at a certain distance, which is the Multi-Frequency Network , MFN) way. In this way, one signal needs to occupy several times the frequency bandwidth, consuming precious spectrum resources. [0003] With the increasingly tight spectrum resources and the development of signal processing technology, the SFN networking method has become a hot topic. The so-called single frequency network (SFN) refers to several...
