Problems solved by technology

However, in such a frame structure, if the transmission delay between two opposite transmission blocks is too long, the efficiency of bidirectional transmission will be reduced, and if the transmission delay is too short, available resources will be wasted
Therefore, the frame structure of time division duplex must be limited in use.
[0006] For the frame structure of frequency division duplex, because the transmission blocks of two opposite directions can be configured in two different frequency channels (that is, two frame sequences) in the same time interval, it can effectively reduce the two The transmission delay between transmissions in opposite directions, but there will still be a transmission delay between two transmissions in the same direction (that is, between the first transmission and the second transmission of the same device)

Abstract

The communication device and communication method of the present invention adopt a frame structure different from the frame structure adopted by the traditional communication system. A frame structure adopted by the present invention includes a plurality of control blocks and a plurality of data blocks, and the plurality of control blocks and the plurality of data blocks are distributed based on a plurality of scheduling cycles of a plurality of time lengths in multiple channels. Another frame structure adopted by the present invention includes multiple frame sequences corresponding to different channels, and the multiple frame sequences are asynchronous in the time domain.

Description

【Technical field】 [0001] The invention relates to a communication device and a communication method thereof. 【Background technique】 [0002] Whether it is to avoid conflicts within the system or to increase resource utilization, many communication systems will set schedules for different requirements, and the frame structure is commonly used. However, there are still many problems that have not been overcome in the frame structure adopted by the traditional communication system. [0003] For example, under a cellular communication system (Cellular Communication System) or a device-to-device communication system (D2D Communication System), when a base station or a transmitting user terminal (Transmitting User Terminal) wants to transmit data to a receiving user terminal In the case of Receiving User Terminal (that is, the application of one-way transmission), the base station or the transmitting user terminal usually broadcasts control information periodically, and the recei...
