Example Embodiment

[0028] In the embodiments of the present application, words such as "optionally" or "for example" are used as examples, illustrations, or illustrations. Any embodiment or design solution described as "optional" or "for example" in the embodiment of the present invention should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, the words "optionally" or "for example" are used to present related concepts in a specific manner.

[0029] This application can be applied to LTE-NR dual-connection scenarios, such as figure 1 As shown, the LTE base station and the NR base station are deployed on the same site. Among them, the NR base station is not deployed independently. It uses the LTE-NR dual connection mode to provide services for 5G terminals. The LTE base station and the NR base station can be outdoor macro base stations to facilitate 5G provides as much coverage as possible in the initial commercial stage. Since the...

Abstract

Embodiments of the present application provide a system dual-connection scheduling strategy and an apparatus thereof, relating to the field of communications, which does not support LTE-NR dual-function terminal can effectively improve the spectrum efficiency of the system without affecting the terminal experience. The method comprises the following steps: the first base station determines that the terminal does not have LTE support. At NR dual function, receiving a measurement report of cell signal quality including an LTE cell and an NR cell reported by the receiving terminal, wherein the LTE cell and the NR cell are first respectively, under the coverage of the base station, The first base station judges whether the signal quality of the LTE cell and the NR cell meets the preset condition. If the signal quality meets the preset condition, the first base station sends the first RRC reconfiguration message and the first configuration information to the terminal and the second base station, respectively, so that the second base station establishes the SRB3 and the DRB2 for the terminal according to the first configuration information. If not, the first base station establishes a DRB1 for the terminal. Embodiments of the present application are used to improve system spectrum utilization without affecting the terminal experience.

Description

technical field [0001] The present application relates to the communication field, and in particular to a system dual connection scheduling strategy and device. Background technique [0002] Dual connectivity is an important solution for the 5th-Generation mobile communication technology (5G) system, including Long Term Evolution-New Radio (LTE-NR) dual connectivity and new air interface-New Radio ( New Radio-New Radio, NR-NR) dual connection. Among them, the LTE-NR dual connectivity function is a mandatory function for 5G NR non-independent deployment scenarios. LTE-NR dual connectivity can use LTE as the coverage layer and NR as the capacity layer. 5G terminals working in dual connectivity mode can experience the performance gains brought by both LTE and NR systems. However, for some LTE-NR dual connectivity frequency band combinations, self-interference will be generated when 5G terminals transmit two systems at different frequencies at the same time, and when the recei...
