Description

Communication method and device
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a communication method and a device thereof.
Background
A user equipment (e.g., User Equipment (UE)) is in a connected state, and when the signal quality of a serving cell of the UE degrades to a certain degree, the serving cell of the UE is changed through cell handover or cell reselection, so as to ensure the continuity of the UE service. Cell handover or cell reselection is dependent on the measurement results. With the development of mobile communication technology, LTE-a Pro (long term evolution-advanced) has begun to be commercially deployed, i.e. 4.5-generation (4.5G) communication technology, and New Radio (NR) (i.e. 5G) communication technologythGeneration, 5G)) is in the standard setting. The 4.5G system improves the rate, throughput, etc. by aggregating more carriers or by multiple connections, so that the deployment density of the base station is increased. The 5G system will use the frequency band of better frequency, and in order to guarantee the throughput and mobility of users, it is also necessary to deploy dense base stations. Under the condition that 4.5G systems and 5G systems are densely deployed with base stations, UE is required to measure a plurality of same-frequency or different-frequency cells around the UE. Multiple communication systems may coexist, for example, a 4.5G system and a 5G system may coexist, which requires the UE to perform inter-system measurement on the multiple communication systems. In other words, when the UE performs cell handover or cell reselection, it needs to measure the neighboring cells with the same frequency, measure the cells with different frequencies, and measure the cells with different systems to obtain the measurement result.
Currently, a concept of synchronization signal block measurement timing configuration (SMTC) is introduced in a 5G system. The SMTC may be a window configured by the network for the UE to determine the location of a Synchronization Signal Block (SSB) of each cell on a frequency point. The network ensures that the UE can find the SSB of each cell on the frequency point in the SMTC window through the cooperation of each base station, so that the UE only needs to perform SSB measurement in the SMTC window and does not need to perform SSB measurement outside the window. By adopting the SMTC, the position of the SSB can be rapidly and accurately acquired in a multi-beam (beam) scene, and the measurement effectiveness is ensured.
The Measurement Gap (MGAP) may be a reserved period of time. In some examples, the UE may not send and receive any data during this time, but rather perform inter-frequency measurements during this time. The UE in the connected state can normally complete the measurement only when the window of the SMTC is completely covered by the MGAP, otherwise, the measurement cannot be normally completed, thereby affecting the measurement result and affecting the continuity of the service. When the SMTC window is not completely covered by the MGAP, how to ensure that the UE in the connected state can normally complete the measurement is an urgent technical problem to be solved.
Disclosure of Invention
The embodiment of the application provides a communication method and a communication device, which can optimize the effectiveness of a measurement result and the continuity of a service.

In the first aspect of the embodiment of the present application, when the ue is in an idle state or an inactive state according to the configuration information, the ue measures the synchronization signal of the second cell to obtain information of a time difference between the first cell and the second cell, so that the ue reports the measurement result to the access network device, and the access network device adjusts the window of the SMTC according to the measurement result, so that the window of the SMTC is covered by the MGAP, thereby ensuring that the ue in a connected state can normally complete measurement, and ensuring validity of the measurement result and continuity of a service.
The second cell is a cell to be measured, and the number of the second cells may be one or multiple, and the specific number is not limited. The second cell may be an intra-frequency cell of the first cell, an inter-frequency cell of the first cell, or an inter-system cell of the first cell. The second cell may be designated by the access network equipment or may be autonomously determined by the user terminal.
In a possible implementation manner, the configuration information includes frequency information of the second cell, and the frequency information may indicate a frequency point. At this time, the configuration information may indicate that the user equipment measures the synchronization signals of all the cells on the frequency point when the user equipment is in an idle state or an inactive state, so as to obtain information of the time difference between each cell and the first cell. The configuration information may also indicate that the user terminal is in an idle state or an inactive state, and measures a synchronization signal of a certain cell on the frequency point, where the cell may be a second cell designated by the access network device, and obtains information of a time difference between the second cell and the first cell. The access network equipment may not specify which cell on the frequency point to measure.

In a possible implementation manner, the user terminal sends the measurement result to the access network device in case of receiving the query message from the access network device. The query message of the access network device may be used to query the measurement result of the specified cell, and may also be used to query the measurement results of all cells measured by the user equipment. The user terminal feeds back the measurement result to the access network equipment according to the query message so that the access network equipment can adjust the time window, and the user terminal can normally complete the measurement when being in a connected state, thereby ensuring the validity of the measurement result and the continuity of the service.
In a possible implementation manner, the user terminal receives time window information from the access network device, where the time window information includes an adjusted time window, and the time window information is used to indicate that the user terminal is in a connected state, and measure a synchronization signal in the adjusted time window, so as to ensure that the measurement can be completed normally when the user terminal is in the connected state, thereby ensuring validity of a measurement result and continuity of a service.

Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.
The technical names or terms related to the embodiments of the present application will be described below.
The SMTC may be a window configured by the network for the UE to determine the SSB location of each cell on one frequency point. The network ensures that the UE can find the SSB of each cell on the frequency point in the SMTC window through the cooperation of each base station, so that the UE only needs to perform SSB measurement in the SMTC window and does not need to perform SSB measurement outside the window, and the search amount of the UE is reduced.
The MGAP may be a period of time, during which the UE will not send and receive any data, and tune the receiver to the frequency point of the target cell to perform inter-frequency measurement or inter-system measurement, and then switch to the current serving cell after the time of the MGAP is over. In the embodiment of the present application, in the MGAP, the UE does not send and receive any data, but performs intra-frequency measurement, inter-frequency measurement, or inter-system measurement.
The same frequency measurement may be that the current serving cell of the UE and the target cell to be measured are on the same carrier frequency point or central frequency point. The pilot frequency measurement may be that the current serving cell of the UE and the target cell to be measured are not on the same carrier frequency point. The inter-system measurement may be that the current serving cell of the UE and the target cell to be measured belong to different communication systems, for example, the current serving cell belongs to a 4G communication system, and the target cell belongs to a 5G communication system.
The system frame number and radio frame boundary time deviation (SFTD) may be the time deviation between the frame boundaries of the serving cell and the target cell of the UE on the frame for the same system frame number. The SFTD may represent a time difference between the serving cell and the target cell. In the scenario of dual connectivity, SFTD may represent the time difference between the primary cell and the secondary cell. In this embodiment, the SFTD may represent a time difference between a first cell and a second cell, where the first cell is a serving cell of the UE and the second cell is a target cell to be measured.
The idle state may be a state in which the UE and the base station are in a state in which Radio Resource Control (RRC) connection is not established between the UE and the base station. The connected state, also called an active state, may be a state in which the UE and the base station are in a state when the UE establishes an RRC connection with the base station. In the inactive state, a base station connected between UEs stores context information of the UEs, so that the UEs can quickly recover from the inactive state to the connected state, thereby reducing the time delay of communication interruption.
Please refer to fig. 1, which is a schematic flowchart of Radio Resource Management (RRM) measurement in a dual connectivity scenario. The dual connectivity scenario includes a UE, a master base station (MN), and a secondary base Station (SN), where the master base station and the secondary base station may belong to different communication systems, for example, the master base station may be a base station in a 5G system, the secondary base station may be a base station in a 4G system, or the master base station may be a base station in a 4G system, and the secondary base station may be a base station in a 5G system. The flow diagram shown in fig. 1 may include the following steps:
step 1, the main base station sends RRC connection reconfiguration information to the UE. Accordingly, the UE receives the RRC connection reconfiguration message from the primary base station.
And under the condition that the main base station and the UE are in a connected state, the main base station sends an RRC connection reconfiguration message to the UE. The RRC connection reconfiguration message includes measurement configuration information of the secondary base station, so that the UE performs measurement according to the measurement configuration information of the secondary base station and feeds back a measurement report to the primary base station. Assuming that the secondary base station to be added to the dual-connection is a base station in a 5G system, the measurement configuration information of the secondary base station includes measurement configuration information of the NR cell, including a system to be measured, a frequency point, cell information, a measurement report reporting condition, MGAP information, SMTC information, and the like.
And step 2, the UE sends an RRC connection reconfiguration completion message to the main base station. Accordingly, the primary base station receives the RRC connection reconfiguration complete message from the UE.
Wherein, the RRC connection reconfiguration complete message is used to indicate that the RRC connection reconfiguration is complete.
And step 3, when the UE receives the RRC connection reconfiguration message, measuring the cell according to the measurement configuration information of the secondary base station, and feeding back a measurement report to the main base station.
And the UE measures the surrounding cells according to the content included in the measurement configuration information of the secondary base station.
And when the UE meets the measurement report reporting condition, feeding back the measurement report to the main base station. The measurement report may include measurements of signal strength, signal quality, etc. of the cell.
And 4, the main base station selects the auxiliary base station according to the measurement report and sends an auxiliary base station adding request message to the auxiliary base station. Accordingly, the secondary base station receives a secondary base station addition request message from the main base station.
And 5, the auxiliary base station agrees to add, and sends an auxiliary base station adding response message to the main base station, wherein the auxiliary base station adding response message is used for responding to the auxiliary base station adding request message. Accordingly, the primary base station receives the secondary base station addition response message from the secondary base station.
And step 6, the main base station sends RRC connection reconfiguration information to the UE. Accordingly, the UE receives the RRC connection reconfiguration message from the primary base station.
And 7, the UE sends an RRC connection reconfiguration completion message to the main base station. Accordingly, the primary base station receives the RRC connection reconfiguration complete message from the UE.
And 8, the main base station sends a secondary base station reconfiguration completion message to the secondary base station. Accordingly, the secondary base station receives the secondary base station reconfiguration complete message from the main base station.
And 9, the UE and the secondary base station execute a random access process so that the UE establishes RRC connection with the secondary base station.
In fig. 1, when the UE is in a connected state, the primary base station sends measurement configuration information of the secondary base station to the UE, so that the UE performs measurement according to the measurement configuration information of the secondary base station, and feeds back a measurement report, which is convenient for the primary base station to select the secondary base station. However, since there is no reference time between the primary base station and the secondary base station, for example, there is no reference time between the 4G base station and the 5G base station, the SMTC information and the MGAP information are not aligned, which further affects the UE to normally complete the measurement and affects the validity of the measurement report. There is no base station time between the primary base station and the secondary base station, and in a special scenario, a Frequency Division Duplex (FDD) base station with frequency synchronization may cause a problem that SMTC information configured for the UE is not aligned with MGAP information when the time between networks is not synchronized or the timing difference is not obtained.
The SMTC information is not aligned with the MGAP information, as shown in fig. 2, which is a comparison between the window of the SMTC and the MGAP. The schematic shown in fig. 2 includes three scenarios:
scenario 1, in which the UE is in a connected state, the measurement can be done normally, although the window of the SMTC is not completely aligned with the MGAP, but the window of the SMTC is completely covered by the MGAP.
In scenario 2, the window of the SMTC partially coincides with the MGAP, that is, the window of a part of the SMTC is covered by the MGAP, and the remaining part is not covered by the MGAP.
In scenario 3, the window of the SMTC is completely misaligned with the MGAP, and the UE cannot normally complete the measurement in this scenario.
The above scenario is merely an example, and the example of fig. 2 does not exclude other possibilities, such as the case where the SMTC window coincides with the MGAP, or the case where the SMTC window is longer than the MGAP.
In view of the fact that reference time does not exist between base stations and the window of the SMTC is not completely covered by the MGAP, embodiments of the present application provide a communication method and a device thereof, where when the UE is in an idle state or an inactive state, the UE measures a time difference between a first cell and a second cell to obtain a measurement result, and feeds back the measurement result to the base station, so that the base station adjusts SMTC information according to the measurement result, so that the window of the SMTC is covered by the MGAP, thereby ensuring that the UE in a connected state can normally complete measurement and ensuring validity of the measurement result and continuity of a service.
Referring to fig. 3, a schematic diagram of a network architecture to which an embodiment of the present application is applied is shown, where the network architecture includes a user terminal 10 and an access network device 20.
User terminal 10 may include, among other things, various handheld devices having wireless communication capabilities, vehicle mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem; it may also include a UE, a subscriber unit (MS), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, a Personal Digital Assistant (PDA) computer, a tablet computer, a wireless modem (modem), a handheld device (hand held), a laptop computer (laptop computer), a cordless phone (cordless phone) or a Wireless Local Loop (WLL) station, a Machine Type Communication (MTC) terminal, a Mobile Station (MS), a terminal device (terminal device) or a relay user equipment, etc. The relay user equipment may be, for example, a 5G home gateway (RG). For convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as a user equipment, and the user equipment is described by taking a UE as an example.
The access network device 20 may be an evolved Node base station (eNB or eNodeB) in a Long Term Evolution (LTE) system, an upgraded eNB, that is, a next generation evolved Node b (ng-eNB), an access network device such as a next generation base station (gNB) in a 5G system, or an access network device in a future communication system.
In this embodiment, the ue 10 supports time difference measurement, for example, SFTD measurement, and the access network device 20 may select a ue that supports SFTD measurement according to capability information of each ue.
In this embodiment, the access network device 20 determines configuration information, where the configuration information indicates that when the user terminal 10 is in an idle state or an inactive state, a time difference is measured, where the time difference is a time difference between a first cell and a second cell, and the first cell is a serving cell of the user terminal. The access network device 20 sends the configuration information to the user terminal 10. When receiving the configuration information, the user terminal 10 measures the synchronization signal of the second cell according to the configuration information to obtain a measurement result, where the measurement result includes information of a time difference between the first cell and the second cell.
Then, the user terminal 10 may report the measurement result to the access network device 20, so that the access network device 20 adjusts the SMTC information according to the measurement result, so that the SMTC information is covered by the MGAP information, thereby ensuring that the user terminal in the connection state can normally complete the measurement, and ensuring the validity of the measurement result and the continuity of the service.
It is understood that the second cell is a cell to be measured, and may be a cell to be measured designated by the access network device 20, or a cell to be measured autonomously determined by the user terminal 10. The number of the second cells may be one or more, and the specific number is determined according to the specific situation.

Referring to fig. 4, a flowchart of a communication method provided in the embodiment of the present application is shown, where the flowchart may include, but is not limited to, the following steps:
step 101, the access network device determines configuration information.
The configuration information is used to indicate that the UE is in an idle state or an inactive state, and measure a time difference, where the time difference is a time difference between a first cell and a second cell, the first cell is a serving cell of the UE, that is, a cell currently providing service for the UE, and the second cell is a cell to be measured, and may be specified by the access network device or may not be specified by the access network device, and is autonomously determined by the UE.
In a possible implementation manner, the configuration information may only indicate that the UE measures the time difference when the UE is in the idle state or the inactive state, but does not indicate which second cell or which second cells measure the time difference between the first cell and the second cell. In this case, the UE may autonomously determine which second cell or cells to measure for the time difference when it is in the idle state or the inactive state, upon receiving the configuration information. For example, the UE determines the second cell to be measured according to System Information Block (SIB) information of the first cell, and specifically may determine the second cell to be measured according to at least one of SIB2 information, SIB4 information, or SIB5 information of the first cell. The SIB2 information includes cell access information and radio channel configuration parameters, the SIB4 information includes co-frequency neighboring cell reselection information, and the SIB5 information includes inter-frequency reselection information.
In another possible implementation manner, the configuration information includes frequency information of the second cell, that is, information of a frequency point where the second cell is located, and is used to indicate the frequency point where the second cell is located. At this time, the configuration information may be used to indicate that the UE is in an idle state or an inactive state, and perform time difference measurement on all cells on the frequency point; the method can also be used for measuring the time difference of a certain cell or certain cells on the frequency point when indicating that the UE is in an idle state or an inactive state, and the specified cell is the second cell; the method and the device can also be used for indicating that the UE performs time difference measurement on the cell on the frequency point when the UE is in an idle state or an inactive state, but do not explicitly indicate which cell or cells to perform time difference measurement, and the UE can autonomously determine the second cell to be measured on the frequency point. When the UE autonomously determines the second cell to be measured on the frequency point, the determination may also be performed according to at least one of SIB2 information, SIB4 information, or SIB5 information of the first cell.
In yet another possible implementation manner, the configuration information includes identification information of the second cell, and the identification information may be a cell Identity (ID), a cell number, and the like, and is used for identifying the cell to be measured. It will be appreciated that this approach is dictated by the access network equipment which cell or cells the UE makes the time difference measurements on.
The time difference between the first cell and the second cell may be an SFTD between the first cell and the second cell, and the configuration information may be an SFTD measurement indication information used for indicating that the UE is in an idle state or an inactive state, and measuring the SFTD between the first cell and the second cell.
The access network device may determine a bearer of the configuration information when determining the configuration information, that is, determine what message to send the configuration information to the UE, so that the access network device sends the configuration information to the UE.
Step 102, the access network equipment sends configuration information to the UE. Accordingly, the UE receives configuration information from the access network device.
In one possible implementation, the access network device sends the configuration information to the UE through a system message block of a broadcast message. Specifically, the access network device sends the configuration information to the UE through the SIB2, SIB4, or SIB5 of the broadcast message, that is, the configuration information is carried in the neighboring cell configuration information of the SIB2, SIB4, or SIB5 of the broadcast message. In this way, the UE can acquire the configuration information from SIB2, SIB4, or SIB5 information, and perform time difference measurement according to the configuration information. It can be understood that this way is that the access network device issues in advance so that the UE measures the time difference when in the idle state or the inactive state.
In another possible implementation, the access network device sends the configuration information to the UE through an RRC connection release message. The RRC connection release message is used for indicating to release the RRC connection between the UE and the access network equipment, so that the UE and the access network equipment enter an idle state or an inactive state, and the configuration information is carried in the RRC connection release message, so that the UE can immediately start measurement of the time difference when entering the idle state or the inactive state.
Step 103, the UE measures the synchronization signal of the second cell to obtain a measurement result.
And when receiving the configuration information and being in an idle state or an inactive state, the UE measures the synchronization signal of the second cell to obtain a measurement result, wherein the measurement result comprises information of the time difference between the first cell and the second cell. Specifically, the UE measures the time information of the synchronization signal of the second cell by using the time information of the synchronization signal of the first cell as reference time information, so as to obtain information of a time difference between the first cell and the second cell, that is, obtain a time difference between the second cell and the first cell.
In a possible implementation manner, when receiving the configuration information and being in an idle state or an inactive state, the UE measures SFTD between the second cell and the first cell to obtain a measurement result, where the measurement result includes SFTD between the first cell and the second cell. Specifically, the UE measures the frame boundary time of the system frame number of the synchronization signal of the second cell by using the frame boundary time of the system frame number of the synchronization signal of the first cell as the reference time, so as to obtain the SFTD between the first cell and the second cell, that is, obtain the SFTD of the second cell relative to the first cell.
The UE may save the measurement results after obtaining the measurement results. If the number of the second cells is more than one, the UE stores the corresponding relationship between the measurement results and the second cells, for example, the number of the second cells is three, i.e., the second cell 1, the second cell 2, and the second cell 3, and the UE stores the time difference 1 between the second cell 1 and the first cell, the time difference 2 between the second cell 2 and the first cell, and the time difference 3 between the second cell 3 and the first cell.
In the embodiment shown in fig. 4, the access network device determines and sends configuration information to the UE, where the configuration information is used to indicate that the UE is in an idle state or an inactive state, and measure a time difference between the first cell and the second cell, so that the access network device obtains the time difference between the first cell and the second cell to perform corresponding adjustment, thereby ensuring that the user terminal in a connected state can normally complete measurement, and ensuring validity of a measurement result and continuity of a service.
As a possible implementation manner, step 103 further includes the following steps:
and step 104, the UE sends the measurement result to the access network equipment. Accordingly, the access network equipment receives the measurement results from the UE.
The UE may send the measurement result to the access network device in three ways:
in the first mode, when the UE triggers to establish the RRC connection again or triggers to recover the RRC connection, the UE sends the measurement result to the access network device through the RRC establishment request message or the RRC recovery request message, where the measurement result is carried in the RRC establishment request message or the RRC recovery request message.
In the second mode, after establishing the RRC connection or recovering the RRC connection, the UE sends the measurement result to the access network device. The measurement result may be sent to the access network device by using an RRC setup complete message or carrying an RRC recovery complete message, where the measurement result is carried in the RRC setup complete message or carrying the RRC recovery complete message.
In the third mode, the UE sends the measurement result to the access network device when receiving the query message from the access network device, that is, the query message triggers the UE to report the measurement result. The query message may be used to query the measurement result of the specified cell, or may be used to query the measurement results of all cells measured by the UE.
And 105, the access network equipment adjusts the time window according to the measurement result to obtain time window information.
And the access network equipment adjusts the time window according to the measurement result to obtain the time window information. Wherein the time window may be a window of SMTC. Within the window of SMTC, the UE may perform SSB measurement on each cell on the frequency point for cell handover or cell reselection. The time window information includes an adjusted time window, i.e., a window including an adjusted SMTC, which is completely covered by the MGAP, or which is aligned with and completely covered by the MGAP. And when the UE is in a connected state, carrying out synchronous signal measurement on each cell on the frequency point in the window of the adjusted SMTC. The synchronization signal measurement is also referred to as SSB measurement.
Specifically, the access network device adjusts the window of the SMTC according to the information of the time difference between the first cell and the second cell, so that the adjusted window of the SMTC is completely covered by the MGAP.
In a possible implementation manner, the access network device adjusts the MGAP according to the measurement result, so that the adjusted MGAP completely covers the window of the SMTC, so as to ensure that the UE in the connected state normally completes the measurement.
Step 106, the access network equipment sends time window information to the UE. Accordingly, the UE receives time window information from the access network device.
After adjusting the window of the SMTC, the access network device sends the adjusted window of the SMTC to the UE, so that when the UE is in a connected state, the SSB measurement is performed within the adjusted window of the SMTC. Or after the access network equipment adjusts the MGAP, the access network equipment sends the adjusted MGAP to the UE, so that the UE can normally complete the measurement when in the connected state.
The time window information may be sent through an RRC connection reconfiguration message, where the time window information is carried in the RRC connection reconfiguration message.
Step 106 is similar to step 1 in fig. 1, except that the RRC connection reconfiguration message in step 1 includes SMTC information pre-configured by the base station, and the RRC connection reconfiguration message in step 106 includes adjusted SMTC information.
And 104-106, the UE reports the measurement result to the access network device, so that the access network device adjusts the time window according to the measurement result to obtain time window information, and sends the time window information to the UE, so that when the UE is in a connected state, the SSB measurement is performed in the time window indicated by the time window information, thereby ensuring that the UE in the connected state can normally complete the measurement, and ensuring the validity of the measurement result and the continuity of the service.
As a possible implementation manner, if the UE is in an idle state or an inactive state, cell reselection occurs, and the reselected cell does not belong to the second cell, the UE may discard the measurement result between the second cell and the first cell. For example, the first cell is cell 1, the second cell includes cells 2 to 4, the reselected cell is cell 5, the UE stores the time differences between cells 2 to 4 and cell 1, respectively, before performing cell reselection, and the reselected cell is not included in the second cell, then the UE discards the time differences between cells 2 to 4 and cell 1, respectively.
As a possible implementation manner, if the UE is in an idle state or an inactive state, cell reselection occurs, and the reselected cell belongs to the second cell, the UE continues to include the measurement result between the reselected cell and the first cell. For example, the first cell is cell 1, the second cell includes cells 2 to 4, the reselected cell is cell 3, the UE stores the time differences between cells 2 to 4 and cell 1, respectively, before performing cell reselection, and the reselected cell is included in the second cell, the UE continues to store the time differences between cells 3 and cell 1, respectively.
