Detailed Description
Currently, how to measure the inter-system neighbor cell when the UE resides in the NR network is not given in the protocol.
Therefore, in the method, pre-generated time slice use planning information is acquired before the inter-system neighbor cell measurement of NR is performed. The time slice use planning information is generated in advance, so that the position and the length of the time slice required by real-time calculation are not needed, and only whether the time window required by the frequency point of the adjacent cell to be measured of the different system is allowed to be used is needed to be judged, if the time window required by the frequency point of the adjacent cell to be measured of the different system is allowed to be used, the frequency point of the adjacent cell to be measured of the different system can be directly measured, and therefore the power consumption required by the UE for measuring the adjacent cell to be measured of the different system can be effectively reduced.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a method for measuring a neighboring cell, where the method is applicable to a UE and the UE supports more than two communication systems simultaneously.
In an embodiment of the invention, the UE is camped on an NR network. The NR heterogeneous System may be at least one of Long Term Evolution (LTE), Global System for Mobile Communication (GSM), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TDSCDMA), and other systems.
In the embodiment of the present invention, the UE includes an inter-system measurement unit, and the inter-system measurement unit is configured to measure the frequency point of the neighboring cell to be measured in the inter-system by using the neighboring cell measurement method in the embodiment of the present invention.
Specifically, the inter-system measurement unit may measure the frequency point of the neighbor cell to be measured in the inter-system by using the following steps:
step 11, before NR inter-system neighbor measurement, the inter-system measurement unit acquires periodic time slice usage planning information generated in advance.
Wherein the time slice usage planning information comprises: the method comprises the steps that first time slice use planning information required to be pre-occupied by NR to-be-detected neighbor cell measurement and second time slice use planning information except the first time slice use planning information are obtained.
In an embodiment of the invention, the UE may comprise a slot usage planning unit. The slot usage planning unit may generate the slot usage planning information.
In a specific implementation, the time slice use planning unit may generate the time slice use planning information in multiple ways, which is not limited herein, and only the inter-system measurement unit may determine whether the time window to be pre-occupied by each inter-system neighboring cell frequency point to be measured is allowed to be used based on the time slice use planning information.
In an embodiment of the present invention, the time slice use planning unit may first calculate, according to the network configuration information of the residing NR cell, a measurement period of each frequency point of the NR neighboring cell to be measured and the number of sampling points in each measurement period, and then determine, according to the network configuration information of the NR cell residing in the user equipment, the measurement period of each frequency point of the NR neighboring cell to be measured and the number of sampling points in each measurement period, a period of the time slice use planning information. And finally, the time slice use planning unit maps the pre-occupied time slice of each adjacent region frequency point to be detected NR to the time slice use planning information based on the number of the sample points in the measurement period of each adjacent region frequency point to be detected NR.
Wherein the NR cell includes: the NR service cell, and the same-frequency adjacent cell and the different-frequency adjacent cell of the NR service cell.
In specific implementation, the number of frequency points of the NR adjacent cell to be measured is configured on the network side, and the time slice usage planning unit may calculate, based on the number of frequency points of the NR adjacent cell to be measured configured on the network side, a measurement period of each frequency point of the NR adjacent cell to be measured and the number of sampling points in each measurement period, in combination with specific protocol requirements. The measurement period of each adjacent frequency point to be measured for NR may be the same or different. The number of sampling points in each measurement period of each adjacent frequency point to be detected of NR can be the same or different.
In an embodiment of the present invention, the time slice usage planning unit may combine a specific network connection state when determining the period of the time slice usage planning information according to the network configuration information of the NR cell where the user equipment resides, the measurement period of the frequency point of the neighboring cell to be NR, and the number of sampling points in each measurement period.
Specifically, when the UE is in the NR idle state, since the UE can perform the inter-frequency measurement before and after the NR Paging Occasion (PO) reception, the PO reception can only perform the intra-frequency measurement of the Synchronization Signal Block (SSB) in the Downlink Bandwidth part (DL BWP). For co-frequency measurements where the SSB is not in the DL BWP, only the time before and after PO reception can be used.
Therefore, when the UE is in the NR idle state, the time slice usage planning unit may determine the length of time to be preempted for completing Measurement of all NR neighbor cells based on SSB-based Measurement time Configuration (SMTC) Configuration of each NR cell and the PO of the NR. And then, by carrying out rounding-up processing on the time length which is required to be pre-occupied for completing the measurement of all the NR adjacent regions, the time length after the rounding-up processing is integral multiple of the NR paging cycle, and the cycle of using the planning information by the time slice can be obtained.
When in the NR connection state, since time slices that can be used in a Non-Discontinuous Reception (Non drx) configuration and a Connected state continuous Reception (CDRX) configuration are different, the time slice use planning unit may determine the period of the time slice use planning information based on an SMTC configuration, a configuration of a network Measurement (Measurement) GAP, and a configuration of a CDRX of each NR cell.
In a specific implementation, when the time slice usage planning unit maps the pre-occupied time slice of each frequency point of the adjacent region to be detected NR to the time slice usage planning information based on the number of sample points in the measurement period of each frequency point of the adjacent region to be detected NR, the number of the pre-occupied time slices of each frequency point of the adjacent region to be detected NR in the time slice usage planning information may be at least one, or may be more than two, and only the number of the sample points in the measurement period corresponding to the frequency point of the adjacent region to be detected NR is less than or equal to the number of the sample points in the measurement period corresponding to the frequency point of the adjacent region to be detected NR.
In a specific implementation, the time slice use planning unit may sequence the SMTC periods of the frequency points of the neighbor cells to be detected for NR from large to small, and map the frequency points of the neighbor cells to be detected for NR to available time in the time slice use planning information according to the sequencing order. The frequency points of the same NR neighboring cell to be measured corresponding to the available time in the time slice use planning information may be continuous or segmented, so that the frequency point of each NR neighboring cell to be measured has at least one available subsequent time slice in the time slice use planning information.
Certainly, in order to achieve a better effect, the rules for mapping the frequency points of the same NR neighboring cell to be detected to the planning time slice in different NR system states may be different, and are not particularly limited as long as the time slice usage planning information includes the time slice information of the frequency point of the NR neighboring cell to be detected.
In another embodiment of the present invention, for convenience of use, the generating the time slice use planning information by the time slice use planning unit may further include:
and the time slice use planning unit marks the pre-occupied time slices belonging to the frequency point of the adjacent region to be detected NR in the time slice use planning information as the first time slice use planning information, and marks the time slices except the pre-occupied time slices belonging to the frequency point of the adjacent region to be detected NR as the second time slice use planning information.
By sequencing and numbering the time slices which are pre-occupied by the neighbor cell to be detected by NR in the time slice use planning information and counting and identifying the positions of the time slices which are not pre-occupied by the neighbor cell to be detected by NR, each communication system in the UE can conveniently call the time slice use planning information. For example, after cell measurement is finished, and before cell handover or reselection, system messages may be read based on the slot usage planning information.
In an embodiment of the present invention, in order to enable any one of the NR and the inter-system frame to find a corresponding available time slice in the time slice usage planning information in each cycle period, that is, extend the time slice usage period in the time slice usage planning information to any time of 10.24s, the time slice usage planning information period can be divided by the cycle period of the NR and the inter-system frame. For example, when the inter-system is the LTE system, the system frame cycle period of the NR and LTE systems is 10.24s, so the period of the slot usage scheduling information can be divided by 10.24 s.
In an embodiment of the present invention, in order to facilitate pre-occupying a time slice by each NR system neighboring frequency point to be detected, mapping the time slice to the time slice use planning information, where a period of the time slice use planning information may be an integer multiple of an SMTC period of each NR system neighboring frequency point to be detected.
As described above, the master mode module refers to a set of circuits or devices for enabling the UE to communicate in the current communication standard, and the slave mode module refers to a set of circuits or devices for enabling the UE to communicate in other communication standards.
And step 12, the inter-system measurement unit determines the frequency point of the inter-system neighbor cell to be measured and the position and length of the time window required by the frequency point of each inter-system neighbor cell to be measured.
In specific implementation, taking the inter-system as an LTE system as an example, the position and length of the time window pre-occupied by each LTE frequency point to be detected may be determined in sequence. For example, based on the protocol requirement, when the LTE system is in a Time-division Duplex (TDD) mode, the LTE system needs to include the 0 th subframe and the 5 th subframe of the cell to be measured in LTE. When the LTE system is Frequency-division Duplex (FDD), the location of the time window does not need to be specified, and the length of the time window is 1.1ms, in the case of an MBSFN LTE system, which is a non-multicast/multicast Single Frequency Network (MBSFN), while the MBSFN LTE system needs a continuous time window with a length of 5.33 ms.
In specific implementation, the execution sequence of steps 11 and 12 is not limited, and step 11 may be executed first, and then step 12 is executed, that is, the time slice use planning information is acquired first, and then the position and length of the time window required to be preempted by each inter-system to-be-detected neighboring cell frequency point are determined, or step 12 may be executed first, then step 11 is executed, that is, the position and length of the time window required to be preempted by each inter-system to-be-detected neighboring cell frequency point are determined first, and then the time slice use planning information is acquired. Of course, steps 11 and 12 may also be executed simultaneously, that is, the position and length of the time window to be preempted by the neighboring frequency point to be tested of each inter-system are determined while the time slice use planning information is acquired.
And step 13, the inter-system measurement unit sequentially judges whether the time window to be pre-occupied by the frequency point of the adjacent cell to be detected of each inter-system is allowed to be used or not based on the time slice use planning information.
In an embodiment of the present invention, the UE may further include: and a time slice scheduling management unit. The inter-system measurement unit can judge whether the time window which is required to be pre-occupied by the frequency point of the adjacent region to be measured of each inter-system is allowed to be used or not through interaction with the time slice scheduling management unit.
Specifically, when the time window to be preempted by the frequency point of the inter-system neighbor cell to be tested corresponds to the second time slice usage planning information, the inter-system measurement unit may directly determine that the time window to be preempted by the frequency point of the inter-system neighbor cell to be tested is allowed to be directly used by the inter-system, and at this time, no interaction with the time slice scheduling management unit is required.
When the time window to be pre-occupied by the frequency point of the neighbor cell to be tested of the inter-system overlaps with the first time slice use planning information, the inter-system measurement unit may first send a time slice use request to the time slice scheduling management unit. The time slice scheduling management unit receives the time slice using request sent by the inter-system measuring unit, confirms whether the NR system needs to reserve the overlapped time slices in the current period, and sends an authorization confirmation message to the inter-system measuring unit when the NR system does not need to reserve the overlapped time slices in the current period, otherwise, sends an unauthorized confirmation message.
And when the inter-system measurement unit receives the authorization confirmation message of the time slice scheduling management unit, judging that the time window required by the frequency point of the adjacent cell to be tested of the inter-system is allowed to be used, otherwise, judging that the time window required by the frequency point of the adjacent cell to be tested of the inter-system is not allowed to be used.
In an embodiment of the present invention, when a time window to be pre-occupied by a frequency point of the neighboring cell to be measured in the inter-system overlaps with the first time slice usage planning information, the inter-system measurement unit may also find a time slice that does not need to apply for authorization.
And executing step 14 when the time window required to be pre-occupied by the frequency point of the adjacent cell to be tested of the inter-system is allowed to be used.
And step 14, the inter-system measuring unit measures the frequency points of the neighbor cells to be measured of the inter-system.
In specific implementation, after the time window required to be preempted by the frequency point of one inter-system neighbor cell to be tested is judged to be allowed to be used, the frequency point of the judged inter-system neighbor cell to be tested is measured, whether the time window required to be preempted by the frequency points of two or more inter-system neighbor cells to be tested is allowed to be used can also be continuously judged, and after the judgment on whether the time window required to be preempted by the frequency points of all inter-system neighbor cells to be tested is allowed to be used, the frequency point of the judged inter-system neighbor cell to be tested is measured, so long as the measurement on the frequency point of the inter-system neighbor cell to be tested, which is allowed to be used by the time window, can be completed.
In a specific implementation, when the time window to be preempted by the frequency point of the inter-system neighbor cell to be tested is not allowed to be used, the inter-system measurement unit may recalculate another time window for the current frequency point of the inter-system neighbor cell to be tested, or directly determine whether the time window to be preempted by the frequency point of another inter-system neighbor cell to be tested is allowed to be used.
If another time window is recalculated for the frequency point of the current neighbor cell to be measured of the inter-system, the inter-system measurement unit still needs to judge whether the usage is allowed or not for the recalculated time window. When use is allowed, step 14 is performed. Of course, it may also be directly determined whether the pre-occupied time window required by the frequency point of the other inter-system neighbor cell to be tested is allowed to be used, and when the use is allowed, step 14 is executed. The method can be used only by judging the time windows corresponding to the frequency points of all the inter-system neighbor cells to be tested and measuring the frequency points of the inter-system neighbor cells to be tested corresponding to the allowed time windows.
It can be understood that, when determining whether the time window required to be preempted by the frequency point of another neighboring cell to be tested of the inter-system is allowed to be used, the implementation may be performed based on the description whether the time window required to be preempted by the frequency point of the neighboring cell to be tested of the inter-system is allowed to be used, which is not described herein again.
As can be seen from the above, in the neighboring cell measurement method in the embodiment of the present invention, when the UE starts the inter-system measurement, the inter-system measurement unit may obtain the time slice usage planning information, and when the time slice usage planning information is used, may first query the attribute of the time slice to be used in the time slice usage planning information by itself. If the time slice does not need to apply for authorization, the time slice is directly used without sending a message to inform the time slice scheduling management unit, if the time slice needs to apply for authorization, the time slice is either searched for another time slice which does not need to apply for authorization, or the time slice scheduling management unit is applied for authorization, and the next time slice is searched after the authorization application fails.
By the method, a plurality of systems of the UE can carry out measurement scheduling according to the time slice use planning information, and the adjacent cell measurement of the UE at any time in an idle state and a connected state is a process which is statically planned in advance, ordered and predictable in position. The time slice use planning information is generated only at a limited moment and belongs to static parameters at other times, so that a large amount of repeated calculation is avoided, different systems can acquire prior information used in each period of time in advance and decide the next operation of the different systems in time, message interaction among modes is reduced, the ordered use efficiency of the time slices is improved, mobility among UE (user equipment) supporting NR (noise reduction) is ensured, the power consumption index is improved, and finally user experience is improved.
