Embodiment Construction

[0030] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0031] As low-frequency spectrum resources are exhausted, high-frequency spectrum resources above 6 GHz have become the focus of attention. According to the channel measurement results, the channel characteristics show the following trend: the higher the frequency band, the smaller the multipath delay. The CP length of Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) depends on the size of the multipath delay. The multipath delay in the high-frequency band becomes smaller, which shortens the length of the CP, thereby shortening...

Abstract

The invention discloses a fusion frame processing method and terminal. The method comprises the following steps: after a sub-frame is received, analyzing the sub-frame, and acquiring PDCCH information of the sub-frame, wherein the PDCCH information contains types of one or more sub-frames behind the sub-frame; determining the types of one or more sub-frames behind the sub-frame according to the PDCCH information, wherein the type of the sub-frame is used for indicating the sub-frame as an uplink sub-frame or a downlink sub-frame; and sequentially sending or receiving the uplink / downlink sub-frames behind the sub-frame according to the types of the one or more sub-frames behind the sub-frame.

Description

technical field [0001] The present invention relates to wireless frame technology, in particular to a processing method and terminal for fusion frames. Background technique [0002] In the era of the 4th Generation mobile communication technology (4G, the 4th Generation mobile communication technology), business types are limited and spectrum resources are relatively concentrated. Therefore, frame parameters / frame structures are relatively fixed for different services, scenarios, and frequency bands. [0003] In the 5G era, the development of the mobile Internet and the Internet of Things will bring more diverse business needs. The vast majority of services have a certain tolerance for delay, and some special services, such as industrial control, are very sensitive to delay, requiring air interface delay of 1ms, and the existing Long Term Evolution (LTE, Long Term Evolution) frame structure minimum scheduling The granularity is 1ms, which cannot meet the delay index require...
