Embodiment Construction

[0058] The application will be described in further detail below in conjunction with the accompanying drawings.

[0059] Embodiments of the present application provide a communication method and device for a dual connectivity system, so as to support relaxation of RRM measurement when the SCG is deactivated, so as to reduce power consumption of terminal equipment. Wherein, the method and the device described in this application are based on the same technical concept. Since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0060] Hereinafter, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

[0061] 1) A terminal device is a device that provides voice and / or data connectivity to users. The terminal device may also be called user equipment (user equipment, UE), mobile ...

Abstract

A communication method and device for a dual-connectivity system are used for supporting relaxation of RRM measurement when an SCG is deactivated so as to reduce power consumption of terminal equipment. The method comprises the following steps that: a first network device determines that a terminal device deactivates an SCG of the terminal device; the first network device sends first information to the terminal device, the first information being used for instructing the terminal device to deactivate a secondary cell group (SCG) of the terminal device, so that the terminal device relaxes SCG RRM measurement after deactivating the SCG; after the terminal device deactivates the SCG according to the first information, the SCG RRM measurement is relaxed, wherein the first network equipment is a master station or an auxiliary station of the terminal equipment. In this way, the relaxed SCG RRM measurement can be supported when the SCG is deactivated, so that the power consumption of the terminal equipment can be reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a communication method and device for a dual connectivity system. Background technique [0002] In a dual connectivity (DC) scenario, two base stations are supported to provide data transmission services for a terminal device at the same time; the base station where the primary cell (PCell) is located is called the primary base station, and the other base station (ie, primary and secondary A base station where a cell (primary secondary cell, PSCell) is located is called a secondary base station. Multiple serving cells in the secondary base station form a secondary cell group (secondary cell group, SCG), and the SCG includes one PSCell and one or more secondary cells (secondary cell, SCell). [0003] In order to save the power consumption of the terminal equipment, an SCG deactivation or suspension (SCG deactivation / SCGsuspend) mechanism is introduced, that...
