Description
Technical Field
The invention relates to the technical field of wireless communication, in particular to a method and a system for measuring pilot frequency adjacent cells under dual connectivity.
Background
In LTE (Long Term Evolution), a UE (User Equipment) in a connected state needs to measure a serving cell and an adjacent cell, so as to evaluate the serving cell and the adjacent cell that meet a reporting condition, and report a measurement report to a base station, and the base station makes a decision whether to switch according to the measurement report of the UE. The neighboring cells may be intra-frequency cells or inter-frequency cells, where the intra-frequency cells refer to neighboring cells having the same frequency as the serving cell of the UE, and the inter-frequency cells refer to neighboring cells having a different frequency from the serving cell of the UE. When measuring the neighboring cell with the same frequency as the serving cell, the UE may receive the reference signal of the neighboring cell with the same frequency while receiving the signal of the serving cell, so as to evaluate whether the signal quality of the neighboring cell meets the reporting condition. When the UE measures a different frequency cell different from the serving cell, for the UE with only one radio frequency transceiver, a measurement gap (length of 6ms) needs to be used. The UE tunes the center frequency of the radio frequency to the pilot frequency in the measurement gap, and then the UE can measure the neighboring cell located at the pilot frequency. After the UE finishes the measurement, the UE needs to tune the center frequency of the radio frequency again, so that the UE can receive signals in the serving cell. The period of the measurement gap may be configured to be 40ms or 80ms, so that the UE may measure the neighboring cell on the pilot frequency for multiple times and obtain multiple measurement values, so as to accurately evaluate whether the neighboring cell meets the reporting condition. The base station may configure a measurement gap for the UE through a Radio Resource Control (RRC) message, where the measurement gap configuration includes a measurement gap repetition period and a measurement gap offset.
Dual connectivity is introduced in LTE release 12 to enable the UE to simultaneously utilize the resources of two base stations for data transmission. For a UE in dual connectivity, a MeNB (Master eNB, Master base station) connected to the UE is responsible for transmission of RRC signaling, a SeNB (Secondary eNB, Secondary base station) is responsible for configuration of SCG (Secondary Cell Group), the SeNB only transmits data, and the SCG Cell configured by the SeNB needs to be sent to the UE through the MeNB by RRC signaling. Both the MeNB and the SeNB may configure multiple serving cells for the UE.
With the continuous development of wireless technologies, 3GPP (3rd Generation Partnership Project) will introduce LTE and NR (New Radio, 5G communication technology) aggregation and LTE and HSPA (high speed Packet Access) aggregation, and both technologies use a scheme similar to dual connectivity to achieve the purpose of simultaneously using wireless resources of an LTE base station and a base station of another standard.
When the inter-frequency adjacent Cell measurement is performed under the dual connectivity, when both the base stations are LTE base stations, the Master base station configures a common measurement gap for the UE, the UE interrupts communication with both the MCG (Master Cell Group) and the SCG (Secondary Cell Group) in the measurement gap, and the UE measures the inter-frequency adjacent cells of the MCG and the SCG in the measurement gap. However, for the case of LTE and NR aggregation, if a common measurement gap is adopted, since the measurement of the UE to the neighboring cell in NR does not require a time length of 6ms, the NR base station interrupts communication with the UE in the measurement gap configured by the LTE base station, resulting in unnecessary time consumption. For the case of LTE and HSPA aggregation, the UE may not be able to perform effective measurement on the HSPA neighbor cell using a measurement gap of 6ms duration.
In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art:
under the dual connectivity based on two different access technologies, when the inter-frequency neighbor cell measurement is performed, the main base station only configures a common measurement gap for the UE, so that the UE cannot simultaneously consider the inter-frequency neighbor cell measurement of the two access technologies.

It should be noted that the sequence of steps S12 and S13 is not limited, and step S12 may be executed first and step S13 may be executed later, or step S13 may be executed first and step S12 may be executed later, or step S12 and step S13 may be executed simultaneously.
Optionally, the first radio access technology is LTE, the second radio access technology is NR, the primary base station is an LTE base station, and the secondary base station is an NR base station; or the first radio access technology is NR, the second radio access technology is LTE, the master base station is an NR base station, and the secondary base station is an LTE base station; the first pilot frequency measurement parameter is a measurement gap, and the second pilot frequency measurement parameter is a measurement gap.

In the method for measuring inter-frequency neighboring cells under dual connectivity provided in the embodiments of the present invention, a main base station configures a first inter-frequency measurement parameter and a first inter-frequency of a first radio access technology for a UE, the main base station configures a second inter-frequency of a second radio access technology for the UE, or an auxiliary base station configures a second inter-frequency measurement parameter and a second inter-frequency of the second radio access technology for the UE, so that inter-frequency measurement parameters corresponding to different access technologies can be configured for the UE under dual connectivity, the UE can measure an adjacent cell on the first inter-frequency configured by the main base station using the first inter-frequency measurement parameter, the UE can measure an adjacent cell on the second inter-frequency configured by the main base station using the first inter-frequency measurement parameter, or measure an adjacent cell on the second inter-frequency configured by the auxiliary base station and an adjacent cell on the second inter-frequency configured by the main base station using the second inter-frequency measurement parameter, therefore, the measurement of the pilot frequency adjacent region of two access technologies can be considered simultaneously.
In this process, the UE needs to make explicit use of which radio frequency transceiver to measure the second pilot frequency. The simple principle is that when the UE measures a first pilot frequency corresponding to a first wireless technology and utilizes a first pilot frequency measurement parameter, the UE measures the first pilot frequency by using a radio frequency transceiver of a serving cell of a main base station; when measuring a second pilot frequency corresponding to a second radio technology, the UE measures the second pilot frequency by using a second pilot frequency measurement parameter (when the secondary base station configures the second pilot frequency measurement parameter), and using the radio frequency transceiver of the serving cell of the secondary base station. And when the secondary base station is not configured with the second pilot frequency measurement parameter, the UE measures the second pilot frequency by using the radio frequency transceiver of the service cell of the service main base station by using the first pilot frequency measurement parameter.
The following describes the method for measuring a different-frequency neighboring cell under dual connectivity in an embodiment of the present invention in detail, taking an example that the first radio access technology is LTE, the second radio access technology is NR, the primary base station is an LTE base station, and the secondary base station is an NR base station.
When the UE uses LTE and NR dual connectivity, the base station needs to configure measurement gaps on the NR side through RRC signaling in addition to the measurement gaps of LTE for the UE, so that the UE can perform inter-frequency measurement on NR.
It is assumed here that the UE first accesses the LTE base station to establish an RRC connection, the LTE base station configures dual connectivity of LTE and NR for the UE according to the capability of the UE and the channel condition where the UE is located, the LTE base station and the NR base station need to interact to configure NR-related parameters, such as NR cell, frequency, and NR access parameter, for the UE, and then the LTE base station sends these parameters to the UE, and the UE accesses the NR after receiving them, thereby implementing dual connectivity. At this time, the LTE base station is the primary base station, and the NR base station is the secondary base station.
The LTE base station may configure inter-frequency measurements of the LTE system for the UE in dual connectivity in order to meet mobility requirements. The LTE base station configures measurement gaps and pilot frequency information to be measured, for example: information such as a measurement object, which is only referred to as pilot frequency in LTE, is transmitted to the UE through the measurement gap and LTE pilot frequency information to be measured.
After receiving the measurement gap and the pilot frequency information in the LTE, the UE measures the adjacent cells on the pilot frequency by using the measurement gap, evaluates whether the reporting condition is met, and sends a measurement report to the LTE base station when the reporting condition is met. In the measurement gap, the UE also maintains communication with the NR base station. The UE has two independent radio frequency transceivers serving a serving cell on the LTE side and a serving cell on the NR side, respectively. At this time, when the UE measures the inter-frequency of LTE, only the radio frequency transceiver of the serving cell on the LTE side is used.
In order to implement transmission of a larger data amount, the NR side may configure carrier aggregation for the UE in dual-connection UE, and at this time, the UE needs to measure an inter-frequency neighboring cell of NR. The measurement of the NR neighbor cell may adopt the following two ways:
mode 1: the LTE base station configures measurement of NR for the UE, including frequency to be measured, reporting conditions and the like, and because the LTE base station configures measurement gaps for the UE, the LTE base station does not need to additionally configure the measurement gaps, only needs to send the NR frequency to be measured, the reporting conditions and the like to the UE, and the UE measures the configured NR frequency by using the original measurement gaps. At this time, the UE measures the NR frequency using the radio frequency transceiver of the serving cell on the serving LTE side.
Mode 2: the method comprises the steps that an NR base station configures a measurement gap for NR pilot frequency measurement for UE, when the NR base station determines that the NR pilot frequency measurement needs to be configured, the NR base station configures the measurement gap for the NR pilot frequency measurement and the frequency to be measured for the UE, and then the measurement gap and the frequency to be measured are sent to the UE through a direct interface, or the measurement gap is sent to the UE through an LTE base station, when the measurement gap is sent to the UE through the LTE base station, the measurement configuration of the NR pilot frequency adopts an encoding mode of an NR system, and the LTE base station is only responsible for transmission and is not responsible for checking. And when the UE receives the measurement about the NR pilot frequency configured by the NR base station, the UE measures an NR pilot frequency adjacent cell by using a radio frequency transceiver of a service cell at the service NR side and a measurement gap of the configured NR pilot frequency measurement, and evaluates whether the reporting condition is met. While the UE measures the NR pilot frequency with this measurement gap, the UE may continue to communicate with the LTE base station.
When the first radio access technology is LTE, the second radio access technology is HSPA, the primary base station is LTE base station, and the secondary base station is HSPA base station, that is, when the UE uses dual connection of LTE and HSPA, the measurement of the inter-frequency neighboring cell under dual connection may be performed with reference to the above-described measurement method of the inter-frequency neighboring cell when the UE uses dual connection of LTE and NR, the only difference being that the inter-frequency measurement parameter corresponding to the HSPA connection and the HSPA base station is the compression mode parameter.
