Problems solved by technology

[0005] It can be seen that the current frame structure and the granularity of frequency domain resources will make the resource allocation not flexible enough, and the time interval between the uplink scheduling mechanism and the HARQ feedback mechanism will cause a large delay, and the 20MHz bandwidth does not meet the high bandwidth requirements.

Abstract

The invention provides a communication method based on a frame structure. The frame structure comprises a first downlink time unit, a protection time unit behind the first downlink time unit and adjacent to the same, an uplink time unit behind the protection time unit and adjacent to the same, and a second downlink time unit behind the uplink time unit and adjacent to the same; the time length of each of the first downlink time unit, the protection time unit, the unlink time unit and the second downlink time unit is configurable; the communication method comprises the following steps: acquiring the time length configuration information of each of the first downlink time unit, the protection time unit and the uplink time unit; communicating with a base station according to the time length configuration information of each of the first downlink time unit, the protection time unit and the uplink time unit. Through the adoption of the method provided by the invention, the time length of each time unit in the frame structure can be flexibly configured according to the actual communication scene, the flexibility of the resource scheduling is improved, and the business requirement in the 5G communication scene is satisfied.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method based on a frame structure. Background technique [0002] Existing 4G and 4.5G mobile communication technologies are based on LTE (Long Term Evolution, Long Term Evolution) and LTE-A (LTE-Advanced) wireless access technology, time-frequency resource granularity, and frame structure. For example, the current LTE system can support a maximum single-carrier bandwidth of 20 MHz. To support a larger bandwidth, it can only rely on the use of carrier aggregation (Carrier Aggregation, CA for short). In addition, the current frame structure mainly includes: FDD (Frequency Division Duplexing, frequency division duplexing) frame structure, TDD (Time Division Duplexing, time division duplexing) frame structure and LAA (LTE Assisted Access, LTE assisted access) unlicensed carrier use dynamic frame structure. Regardless of the frame structure, it includes...
