Problems solved by technology

[0004] 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 and communication apparatus. The communication method comprises a step of carrying out configuration of taking a downlink subframe as a radio frame of an initial subframe, and a step of sending a scheduling signaling to the downlink subframe such that an uplink subframe used for uplink transmission is configured in the radio frame. According to the technical scheme of the present invention, according to a real communication scene, the position and number of the uplink subframes in the radio frame can be flexible configured, the flexibility of resource scheduling is improved, and the service requirement in a 5D communication scene is satisfied.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular, to a communication method and a communication device. 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 inc...
