Problems solved by technology

[0004] However, in the prior art, although different DRX cycles can be configured on both sides of the primary base station and the secondary base station, the user terminal only determines the measurement requirements of the primary base station measurement frequency and the secondary base station measurement frequency according to the primary base station DRX cycle, and does not The use of the DRX cycle of the secondary base station leads to a single way to determine the measurement requirements, which makes it difficult to meet the mobility requirements of the user terminal

Embodiment Construction

[0048] In the prior art, for a user terminal in a connected state, if there is a service requirement, the base station can configure carrier aggregation for the user terminal. In carrier aggregation, a user terminal can simultaneously use resources of multiple component carriers to achieve a high data transmission rate. Usually, component carriers implementing carrier aggregation are all located in the same base station.

[0049] refer to figure 1 , figure 1 It is a schematic diagram of a dual connection working scene in the prior art. In a dual connectivity system, a first base station 11 , a second base station 12 and a user terminal 13 may be included. Wherein, the user terminal 13 can simultaneously utilize resources of the first base station 11 and the second base station 12 for data transmission, which not only improves data throughput, but also improves mobility performance. Generally, data exchange between the first base station 11 and the second base station 12 ta...

Abstract

The invention discloses a method and a device for determining a measurement demand in dual connectivity, a storage medium and a user terminal, and the method comprises the following steps: receiving main base station configuration information from a main base station, wherein the main base station configuration information comprises a main base station DRX period and a main base station measurement frequency; Receiving auxiliary base station configuration information, the auxiliary base station configuration information comprising an auxiliary base station DRX period and an auxiliary base station measurement frequency, and the same measurement frequency in the main base station measurement frequency and the auxiliary base station measurement frequency being a common measurement frequency;And determining the measurement requirements of the measurement frequency of the main base station and the measurement frequency of the auxiliary base station according to the DRX period of the main base station and the DRX period of the auxiliary base station. According to the scheme provided by the invention, the user terminal can select the appropriate DRX period, and then the measurement requirement is determined according to the appropriate DRX period, so that the mobility requirement of the user terminal is met.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for determining measurement requirements in dual connectivity, a storage medium, and a user terminal. Background technique [0002] In the scenario of dual connectivity between a Long Term Evolution (LTE) base station and a New Radio (NR) base station, one of them is a primary base station (Master eNB, MeNB, or MN), and the other is a secondary base station ( Secondary gNB, SeNB, or SN). For example, the LTE base station is the primary base station, and the NR base station is the secondary base station, or the NR base station is the primary base station, and the LTE base station is the secondary base station. [0003] After the user equipment (User Equipment, UE) establishes LTE-NR dual connectivity (referred to as EN-DC), both the primary base station and the secondary base station will configure the measurement for the user terminal, for ex...
