Problems solved by technology

[0004] However, due to reasons such as cost and power consumption, some terminals do not support maintaining dual connections with different communication systems in the uplink direction, so that the terminal cannot use dual connection technology to communicate with different communication systems at the same time

Embodiment Construction

[0025] The method for establishing dual connectivity and the network device provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.

[0027] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects, or to distinguish different processes for the same object, rather than to describe a specific sequence of objects.

[0028] In addition, the terms "including" and "having" mentioned in the description of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, prod...

Abstract

The invention provides a dual connection establishment method and a network device, which relate to the communication field, and can realize the dual connection between the same terminal and two heterogeneous communication systems by adopting an uplink resource frequency division multiplexing mode. The method is applied to a first network device supporting a first standard, and an ideal return interface exists between the first network device and the second network device supporting the second mode. The method includes: transmitting configuration information of a first frequency domain resource to a first terminal and a second network device, so that a second network device transmits configuration information of a second frequency domain resource to the first terminal according to the configuration information of the first frequency domain resource. Thereafter, the first network device receives the uplink signal of the first standard transmitted by the first terminal on the first frequency domain resource, and the second network device receives the uplink signal of the second standard transmitted by the first terminal on the second frequency domain resource. Wherein the first frequency domain resource and the second frequency domain resource belong to the same carrier and there is no intersection.

Description

technical field [0001] The present application relates to the communication field, and in particular to a dual connection establishment method and network equipment. Background technique [0002] Dual connectivity (DC) means that the same terminal, such as user equipment (UE), mobile phone, etc., maintains connections with two communication systems of different standards at the same time, so as to improve resource utilization, increase system capacity, and reduce handover. delay and improve communication quality, etc. For example, the same terminal maintains communication with the fourth generation (4th generation, 4G) communication system such as long term evolution (long termevolution, LTE) and the fifth generation (5th generation, 5G) communication system such as new radio (new radio, NR) at the same time. connect. [0003] At present, dual connectivity between a terminal and different communication systems needs to simultaneously maintain two independent connections in...
