Description

Method and system for measuring different frequency neighbor cells under double connection
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and a system for measuring a dual-connection different-frequency neighbor cell.
Background
In LTE (Long Term Evolution ), a UE (User Equipment) in a connected state needs to measure a serving cell and a neighboring cell, so as to evaluate the serving cell and the neighboring cell that meet a reporting condition, report a measurement report to a base station, and the base station makes a decision about whether to switch according to the measurement report of the UE. The neighbor cell may be a same frequency cell or a different frequency cell, wherein the same frequency cell refers to a neighboring cell having the same frequency as the serving cell of the UE, and the different frequency refers to a neighboring cell having a different frequency from the serving cell of the UE. When the UE measures the neighboring cells of the same frequency as the serving cell, it may receive the reference signals of the neighboring cells of the same frequency while receiving the signals of the serving cell, so as to evaluate whether the signal quality of the neighboring cells satisfies the reporting condition. When a UE measures an inter-frequency cell of a different frequency from a serving cell, a measurement gap (length of 6 ms) needs to be used for a UE having only one radio frequency transceiver. The UE tunes the center frequency of the radio frequency to the different frequency in the measurement gap, and then the UE can measure the neighboring cells located at the different frequency. After the UE finishes the measurement, the UE needs to tune the radio frequency center frequency again so that the UE can receive the signal 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 neighbor cell on the different frequency multiple times and obtain multiple measurement values, so as to accurately evaluate whether the neighbor cell satisfies the reporting condition. The base station may configure one measurement gap for the UE through an RRC (Radio Resource Control ) message, one measurement gap configuration including a measurement gap repetition period and a measurement gap offset.
The dual connectivity is introduced in LTE release 12 to enable the UE to utilize the resources of two base stations simultaneously for data transmission. For a UE in dual connectivity, the connected MeNB (Master eNB) is responsible for transmission of RRC signaling, and the SeNB (secondary eNB, secondary base station) is responsible for configuration of SCGs (Secondary Cell Group ), where the SeNB only transmits data, and the SCG cells configured by the SeNB need to be sent to the UE by RRC signaling through the MeNB. Both the MeNB and the SeNB may configure multiple serving cells for the UE.
With the continuous development of wireless technology, 3GPP (3 rd Generation Partnership Project, third generation partnership project) will introduce aggregation of LTE and NR (New Radio,5G communication technology) and aggregation of LTE and HSPA (High Speed Packet Access ), both technologies use a dual connection-like scheme, so as to achieve the purpose of simultaneously using wireless resources of an LTE base station and another standard base station.
When the two base stations are LTE base stations, the main base station configures a common measurement gap for the UE, the UE interrupts communication with both MCG (Master Cell Group, main cell group) and SCG (Secondary Cell Group, auxiliary cell group) in the measurement gap, and the UE measures the inter-frequency neighbor 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 used, since the measurement of neighboring cells by the UE in NR does not require a time length of 6ms, the NR base station may cause unnecessary time consumption by interrupting communication with the UE in the measurement gap configured by the LTE base station. For the case of LTE and HSPA aggregation, the UE may not be able to make efficient measurements of HSPA neighbors with a measurement gap of 6ms duration.
In the process of realizing the invention, the inventor finds that at least the following technical problems exist in the prior art:
under the double connection based on two different access technologies, when the measurement of the different-frequency neighbor cell is carried out, the main base station only configures a common measurement gap for the UE, so that the UE cannot simultaneously consider the measurement of the different-frequency neighbor cell of the two access technologies.

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 wireless access technology is NR, the second wireless access technology is LTE, the main base station is an NR base station, and the auxiliary base station is an LTE base station; the first inter-frequency measurement parameter is a measurement gap, and the second inter-frequency measurement parameter is a measurement gap.

According to the method for measuring the inter-frequency neighbor cells under the dual connection, the main base station configures a first inter-frequency measurement parameter and a first inter-frequency of a first wireless access technology for the UE, the main base station configures a second inter-frequency measurement parameter and a second inter-frequency measurement parameter of a second wireless access technology for the UE or the auxiliary base station configures the second inter-frequency measurement parameter and the second inter-frequency of the second wireless access technology for the UE, so that the inter-frequency measurement parameters corresponding to different access technologies can be configured for the UE under the dual connection, the UE can use the first inter-frequency measurement parameter to measure the neighbor cells on the first inter-frequency configured by the main base station, and the UE can use the first inter-frequency measurement parameter to measure the neighbor cells on the second inter-frequency configured by the main base station or use the second inter-frequency measurement parameter to measure the neighbor cells on the second inter-frequency configured by the auxiliary base station, so that the measurement of the two inter-frequency neighbor cells can be simultaneously considered.
In this procedure, the UE needs to make an explicit use of which radio transceiver to measure the second inter-frequency. The simple principle is that when the UE measures a first inter-frequency corresponding to a first wireless technology and utilizes a first inter-frequency measurement parameter, a radio frequency transceiver serving a cell of a main base station is adopted to measure the first inter-frequency; and when the UE measures a second inter-frequency corresponding to the second wireless technology, the UE measures the second inter-frequency by using a radio frequency transceiver of a serving cell of the serving auxiliary base station by using a second inter-frequency measurement parameter (when the auxiliary base station configures the second inter-frequency measurement parameter). And when the secondary base station is not configured with the second inter-frequency measurement parameter, the UE measures the second inter-frequency by using the radio frequency transceiver serving the cell of the primary base station by using the first inter-frequency measurement parameter.
The following describes in detail the measurement method of the inter-frequency neighbor cell under dual connection in the embodiment of the present invention, taking the first radio access technology as LTE, the second radio access technology as NR, the main base station as LTE base station, and the auxiliary base station as NR base station as an example.
When the UE uses dual connection of LTE and NR, the base station needs to configure a measurement gap on the NR side through RRC signaling in addition to the measurement gap of LTE for the UE, for the UE to perform inter-frequency measurement on NR.
Here, it is assumed that the UE first accesses the LTE base station, establishes RRC connection, configures dual connection of LTE and NR for the UE according to the capability of the UE and the channel condition where the UE is located, and the LTE base station and the NR base station need to interact so as to configure NR related parameters such as a cell of NR, a frequency of NR, and parameters of accessing NR for the UE, and then send these parameters to the UE through the LTE base station, and after the UE receives, access the NR, thereby implementing dual connection. At this time, the LTE base station is a primary base station, and the NR base station is a secondary base station.
The LTE base station may configure inter-frequency measurements of the LTE system for UEs in dual connectivity in order to meet mobility requirements. The LTE base station configures measurement gaps and inter-frequency information to be measured, for example: and information such as a measurement object, which only refers to different frequencies in LTE, and then sends the measurement gap and LTE different frequency information to be measured to the UE.
After receiving the measurement gap and the inter-frequency information in the LTE, the UE measures adjacent cells on the inter-frequency frequencies 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 remains in communication with the NR base station. The UE has two independent radio frequency transceivers serving the LTE-side serving cell and the NR-side serving cell, respectively. At this time, when the UE measures the different frequencies of LTE, only the radio frequency transceiver serving the serving cell on the LTE side is used.
In order to realize the transmission of larger data volume, the NR side can configure carrier aggregation for the UE, and the UE needs to measure the different-frequency neighbor cell of NR. The measurement of NR neighbors can be done in two ways:
mode 1: the LTE base station configures measurement of NR (radio resource locator) for the UE, wherein the measurement comprises frequency to be measured, reporting condition and the like, and because the LTE base station has configured 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 condition 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 a radio frequency transceiver serving a serving cell on the LTE side.
Mode 2: the NR base station configures measurement gaps of NR inter-frequency measurement for the UE, when the NR base station determines the inter-frequency measurement needing to be configured with NR, the NR base station configures the measurement gaps of NR inter-frequency measurement and the frequency needing to be measured for the UE and then sends the measurement gaps to the UE through a direct interface, or sends the measurement gaps to the UE through an LTE base station, when the measurement configuration of NR inter-frequency is sent to the UE through the LTE base station, the LTE base station only takes charge of transmission and does not check whether the measurement configuration of the part is accurately configured. When the UE receives the measurement about the NR pilot frequency configured by the NR base station, the NR pilot frequency neighbor cell is measured by using a radio frequency transceiver of a serving cell at the serving NR side and a measurement gap of the configured NR pilot frequency measurement, and whether the reporting condition is satisfied is evaluated. The UE may continue to communicate with the LTE base station while the UE measures NR alien frequencies with the measurement gap.
When the first radio access technology is LTE, the second radio access technology is HSPA, the main base station is an LTE base station, and the auxiliary base station is an HSPA base station, that is, when the UE uses LTE and HSPA dual connectivity, measurement of the inter-frequency neighbor under dual connectivity can be performed with reference to the measurement method of the inter-frequency neighbor when the UE uses LTE and NR dual connectivity described above, except that the inter-frequency measurement parameters corresponding to the HSPA connectivity and the HSPA base station are compressed mode parameters.
