Embodiment 1

[0088] Such as figure 2 As shown, in a communication system using time division duplex technology, a frame includes a downlink area, and the downlink area includes a synchronization channel, basic frame information, a control channel area, and a downlink traffic channel, and the basic frame information carries the decoded The content required by the control channel area; wherein, the synchronization channel is located before the basic frame information, the basic frame information is located before the control channel area, and the control channel area is located before the downlink traffic channel.

[0089] The base station sends the frame to the terminal.

Embodiment 2

[0091] Such as image 3 As shown, in a communication system using time division duplex technology, a frame includes a downlink area, and the downlink area includes a synchronization channel, basic frame information, control channel area, downlink feedback channel, and downlink traffic channel. The basic frame information includes Carry the content required for decoding the control channel area; wherein, the synchronization channel is located before the basic frame information, the basic frame information is located before the control channel area, the control channel area is located before the downlink traffic channel, and the downlink feedback channel is located in the control channel between the area and the downlink traffic channel.

[0092] The base station sends the frame to the terminal.

Embodiment 3

[0094] Such as Figure 4 As shown, in a communication system using time division duplex technology, a frame includes a downlink area, and the downlink area includes a synchronization channel, basic frame information, downlink feedback channel, control channel area, and downlink traffic channel, and the basic frame information includes Carry the content required for decoding the control channel area; wherein, the synchronization channel is located before the basic frame information, the basic frame information is located before the control channel area, the control channel area is located before the downlink traffic channel, and the downlink feedback channel is located in the basic frame information between the control channel region.

[0095] The base station sends the frame to the terminal.

Abstract

The invention discloses a frame structure processing method and system, both of which can carry a downlink area in a frame in a communication system using time division duplex technology; the downlink area includes a synchronization channel, basic frame information, a control channel area, a downlink At least one of the traffic channels, the basic frame information carries the content required for decoding the control channel area; and the synchronization channel is located before the basic frame information, the basic frame information is located before the control channel area, and the control channel area is located in the downlink traffic channel before. The base station sends the frame to the terminal. The frame structure processing technology of the present invention, through the setting and use of key parameters such as reasonable subcarrier spacing, number of available subcarriers, number of protected subcarriers, and CP length, solves the problem of large control overhead and high product implementation complexity in existing wireless communication standards To better meet the needs of the rapid development of data users and the future development of the wireless communication industry.

Description

technical field [0001] The invention relates to the communication field, in particular to a frame structure processing method and system. Background technique [0002] With the development of the mobile Internet and the popularization of smart phones, the demand for mobile data traffic is increasing rapidly, and the rapid growth of data services poses a severe challenge to the transmission capacity of mobile communication networks. [0003] The cellular mobile communication system is mainly designed for high-speed mobility and seamless handover of traditional telecommunication services. When it carries large traffic and low-speed IP (Internet Protocol) data packet services, the efficiency is low and the cost is too high. Taking the LTE (Long Term Evolution, Long Term Evolution) standard adopting OFDM (Orthogonal Frequency Division Multiplexing) technology as an example, it is unique in terms of frame structure, resource allocation, control channel, pilot frequency, and netwo...
