Abstract

In the communication method, device, and system provided in the embodiments of the present application, the first network device generates configuration information including information about the first mode and the second mode, and sends the configuration information to the terminal. Wherein, the first mode is used to stagger the first spectrum resource and the second spectrum resource in the time domain for the uplink transmission between the terminal and the first network device and the uplink transmission between the terminal and the second network device, and the second mode The first spectrum resource or the second spectrum resource is used for uplink transmission between the terminal and the first network device and uplink transmission between the terminal and the second network device. The first network device and the second network device serve the terminal together. Through the settings of the above first mode and the second mode, the interference between the network devices when using different spectrum resources can be reduced; and the terminal can know the first mode and the second mode. Mode information, and then pre-adapt to different spectrum resources, reduce the delay of uplink transmission, and improve communication efficiency.

Description

Technical field [0001] Embodiments of the present application relate to communication technologies, in particular to communication methods, devices, and systems. Background technique [0002] With the development of wireless communication technology, the services provided by wireless networks are increasing, and the business of business is increasing, so wireless communication technology is evolving to meet the growing business needs. For example, a single cell or network device has limited bandwidth resources and coverage, which can focus on multiple cells or network devices to provide better services for users. Currently, such centralized resources include, for example, Carrier Aggregation, CAs, Dual Connectivity, DCs. [0003] CA technology uses a plurality of consecutive or discontinuous carrier polymers, and multiple carriers are mainly aggregated in the Media Access Control, Mac), and the delay and synchronization requirements in the MAC layer schedule are higher. DC techno...
