Detailed Description
At present, how to measure the neighboring cells of the different systems when the UE resides in the NR network is not given in the protocol.
Therefore, the embodiment of the invention provides a neighbor cell measurement method, wherein pre-generated time slice use planning information is acquired before the neighbor cell measurement of the different system of NR is carried out. Because the time slice use planning information is generated in advance, the position and the length of the time slice are not required to be calculated in real time, and only the time window required by the frequency point of the adjacent cell to be measured of the different system is required to be judged to judge whether the use is allowed or not, 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, so that the power consumption required by the UE when the adjacent cell to be measured of the different system is measured can be effectively reduced.
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Referring to fig. 1, an embodiment of the present invention provides a neighbor cell measurement method, which is applicable to a UE, and the UE supports more than two communication schemes simultaneously.
In an embodiment of the invention, the UE resides in an NR network. The different system of NR may be at least one of long term evolution (Long Term Evolution, LTE), global system for mobile communications (Global System for Mobile Communication, GSM), wideband code Division multiple access (WidebandCodeDivision Multiple Access, WCDMA), time Division-Synchronous Code Division Multiple Access (TDSCDMA), and the like.
In the embodiment of the invention, the UE comprises a different system measurement unit, and the different system measurement unit is used for measuring the frequency points of the different system neighbor cells to be measured by adopting the neighbor cell measurement method in the embodiment of the invention.
Specifically, the inter-system measurement unit may measure the frequency points of the neighboring cells to be measured of the inter-system by adopting the following steps:
Step 11, before performing the inter-system neighbor measurement of NR, the inter-system measurement unit acquires the periodically generated time slice usage planning information in advance.
Wherein the time slice uses planning information, comprising: the NR to-be-measured neighbor cell measures the first time slice usage planning information required to be preempted and the second time slice usage planning information except for the first time slice usage planning information.
In an embodiment of the present invention, the UE may include a time slice usage planning unit. The time slice usage planning unit may generate the time slice usage planning information.
In a specific implementation, the time slice usage planning unit may generate the time slice usage planning information in a plurality of manners, which is not limited herein, so long as the inter-system measurement unit can determine, based on the time slice usage planning information, whether the time window that needs to be pre-occupied by each inter-system neighbor cell frequency point to be measured is allowed to be used.
In an embodiment of the present invention, the time slice usage planning unit may calculate, according to network configuration information of the residing NR cells, a measurement period of each NR neighboring cell frequency point to be measured and a number of samples in each measurement period, and further determine, according to network configuration information of the residing NR cells of the user equipment, the measurement period of each NR neighboring cell frequency point to be measured and the number of samples in each measurement period, a period of the time slice usage planning information. And finally, the time slice use planning unit maps the pre-occupied time slices of each NR neighbor frequency point to be measured to the time slice use planning information based on the number of the sample points in the measurement period of each NR neighbor frequency point to be measured.
Wherein the NR cell comprises: NR service cell, and same-frequency adjacent cell and different-frequency adjacent cell of the NR service cell.
In a specific implementation, the number of the adjacent frequency points to be measured by NR is configured on the network side, and the time slice use planning unit can calculate the measurement period of each adjacent frequency point to be measured by NR and the number of the sample points in each measurement period based on the number of the adjacent frequency points to be measured by NR configured on the network side and combined with specific protocol requirements. The measurement period of each NR neighbor cell frequency point to be measured may be the same or different. The number of the sample points in each measurement period of each NR neighbor cell frequency point to be measured can be the same or different.
In an embodiment of the present invention, the time slice usage planning unit may be configured to combine a specific network connection state when determining a period of the time slice usage planning information according to network configuration information of an NR cell where the ue resides, a measurement period of each NR neighbor cell frequency point to be measured, and a number of samples in each measurement period.
Specifically, when the UE is in NR idle state, since the UE can perform inter-frequency measurement before and after the reception of the NR paging occasions (Paging Occasion, PO) at this time, the PO can only perform co-frequency measurement of the Synchronization Signal Block (SSB) in the downlink bandwidth portion (Downlink Bandwidth part, DL BWP) at the reception of the PO. For co-channel measurements where SSBs are not inside DL BWP, only the time before and after PO reception can be used.
Thus, when the UE is in NR idle state, the time slice usage planning unit may determine the length of time to camp on required to complete all NR neighbor measurements based on SSB-based measurement time configuration (SS block based RRM Measurement Timing Configuration, SMTC) configuration of each NR cell and the PO of the NR. And performing rounding processing on the time length which is required to be occupied by completing all NR neighbor cell measurement, so that the time length after the rounding processing is an integer multiple of an NR paging period, and the period of the time slice use planning information can be obtained.
When in the NR connected state, the time slices that can be used in the discontinuous reception (Non Discontinuous Reception, nonDRX) and continuous reception (Connected state Discontinuous Reception, CDRX) configuration in the connected state are different, and thus the time slice usage planning unit may determine the period of the time slice usage planning information based on the SMTC configuration, the configuration of the network Measurement (Measurement) GAP, and the configuration of the CDRX of each NR cell.
In a specific implementation, the time slice usage planning unit maps the pre-occupied time slices of each NR adjacent frequency point to be measured to the time slice usage planning information based on the number of the sample points in the measurement period of each NR adjacent frequency point to be measured, where the number of the time slices pre-occupied by each NR adjacent frequency point to be measured in the time slice usage planning information is at least one, or may be more than two, and only is less than or equal to the number of the sample points in the measurement period corresponding to the NR adjacent frequency points to be measured.
In a specific implementation, the time slice usage planning unit may sort SMTC periods of frequency points of the NR neighboring cells to be measured from large to small, and take the frequency points of the NR neighboring cells to be measured according to the sorting order, and map the frequency points into available time in the time slice usage planning information. The frequency points of the same NR neighbor cell to be measured can be continuous or segmented corresponding to the available time in the time slice use planning information, so that the frequency point of each NR neighbor cell to be measured has at least one available subsequent time slice in the time slice use planning information.
Of course, in order to achieve a better effect, the rule of mapping the frequency points of the same NR neighboring cell to be measured into the planning time slices in different NR system states may be different, and the time slices are not particularly limited, as long as the time slice usage planning information includes time slice information of the frequency points of the NR neighboring cell to be measured.
In another embodiment of the present invention, for convenience of use, the time slice usage planning unit generates the time slice usage planning information, and may further include:
And the time slice use planning unit marks the pre-occupying time slices belonging to the NR adjacent cell frequency points to be measured in the time slice use planning information as the first time slice use planning information, and marks the time slices except the pre-occupying time slices belonging to the NR adjacent cell frequency points to be measured as the second time slice use planning information.
By sequencing and numbering the time slices preempted by the NR neighbor cells to be detected in the time slice use planning information, the time slice positions not preempted by the NR neighbor cells to be detected are also counted and identified, so that each communication system in the UE can conveniently call the time slice use planning information. For example, after the cell measurement is finished, before the cell handover or reselection, the system message may be read based on the time slice using the planning information.
In an embodiment of the present invention, in order to enable any frame of the NR and the system frame of the different system to find a corresponding available time slice in the time slice usage planning information in each cycle period, that is, any time when the time slice usage period in the time slice usage planning information is extended to 10.24s, the period of the time slice usage planning information may be divided by the cycle period of the NR and the system frame of the different system. For example, when the different system is an LTE system, the system frame cycle period of both the NR and LTE systems is 10.24s, so the period of the time slice usage planning information may be divided by 10.24 s.
In an embodiment of the present invention, in order to facilitate pre-occupying a time slice for each adjacent cell frequency point to be detected in the NR system, the period of the time slice usage planning information may be an integer multiple of the SMTC period of each adjacent cell frequency point to be detected in the NR system.
As described above, the master mode refers to a set of circuits or devices for causing the UE to communicate in the current communication scheme, and the slave mode refers to a set of circuits or devices for causing the UE to communicate in other communication schemes.
And step 12, the inter-system measurement unit determines the frequency points of the inter-system neighbor cells to be measured, and the position and the length of a pre-occupied time window required by each inter-system neighbor cell frequency point to be measured.
In a specific implementation, taking the different system as an LTE system as an example, the location and the length of a time window occupied by each LTE frequency point to be measured may be determined sequentially. For example, based on protocol requirements, when the LTE system is in Time-division Duplex (TDD) mode, the 0 th subframe and the 5 th subframe of the LTE cell under test need to be included. When the LTE system is a Frequency Division Duplex (FDD), the location of the time window is not required to be specific for the LTE system of the non-multicast/multicast single Frequency network (Multimedia Broadcast multicast SERVICE SINGLE Frequency Network, MBSFN), and the length of the time window is 1.1ms, whereas the LTE system of the MBSFN requires 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, then step 12 may be executed, that is, the time slice usage planning information may be acquired first, then the position and the length of the pre-occupied time window required by each neighboring cell frequency point to be measured in the different system may be determined, or step 12 may be executed first, then step 11 may be executed, that is, the position and the length of the pre-occupied time window required by each neighboring cell frequency point to be measured in the different system may be determined first, and then the time slice usage planning information may be acquired. Of course, steps 11 and 12 may also be executed simultaneously, that is, the position and length of the pre-occupation time window required by each neighboring cell frequency point to be detected in the different system may be determined while the time slice usage planning information is acquired.
And step 13, the inter-system measurement unit sequentially judges whether the time window which needs to be preempted by each inter-system neighbor cell frequency point to be measured 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 needs to be preempted by each inter-system neighbor cell frequency point to be detected is allowed to be used or not through interaction with the time slice scheduling management unit.
Specifically, when the time window in which the frequency point of the neighboring cell to be measured in the different system needs to be pre-occupied corresponds to the second time slice usage planning information, the different system measurement unit may directly determine that the time window in which the frequency point of the neighboring cell to be measured in the different system needs to be pre-occupied is allowed to be directly used by the different system, and at this time, no interaction with the time slice scheduling management unit is required.
When the time window occupied by the frequency point of the neighboring cell to be detected by the different system overlaps with the first time slice use planning information, the different system measurement unit may first send a time slice use request to the time slice scheduling management unit. And the time slice scheduling management unit receives the time slice use request sent by the inter-system measurement unit, confirms whether the overlapped time slices need to be reserved in the current period of the NR system, and sends an authorization confirmation message to the inter-system measurement unit when the overlapped time slices do not need to be reserved in the current period of the NR system, otherwise sends an unauthorized confirmation message.
When the inter-system measurement unit receives the authorization confirmation message of the time slice scheduling management unit, the time window which needs to be preempted by the frequency point of the inter-system neighbor cell to be measured is judged to be allowed to be used, otherwise, the time window which needs to be preempted by the frequency point of the inter-system neighbor cell to be measured is judged to be not allowed to be used.
In an embodiment of the present invention, when a time window in which the frequency point of the neighboring cell to be measured of the different system needs to be pre-occupied overlaps with the first time slice usage planning information, the different system measurement unit may also find a time slice without applying for authorization.
And when the time window which needs to be preempted by the frequency points of the adjacent cells to be detected of the different systems is allowed to be used, executing the step 14.
And 14, the inter-system measurement unit measures the frequency points of the inter-system neighbor cells to be measured.
In a specific implementation, after the time window in which the frequency point of the neighboring cell to be measured in the different system needs to be pre-occupied is determined to be allowed to be used, that is, the determined frequency point of the neighboring cell to be measured in the different system can be measured, whether the time windows in which the frequency points of the neighboring cell to be measured in the different system need to be pre-occupied are allowed to be used or not can be continuously determined, and after the determination that whether the time windows in which the frequency points of the neighboring cell to be measured in the different system need to be pre-occupied are allowed to be used or not is completed, the frequency point of the neighboring cell to be measured in the different system is determined to be measured, so long as the measurement of the frequency point of the neighboring cell to be measured in the different system, which is allowed to be used in the time window, can be completed.
In a specific implementation, when the time window that the frequency point of the neighboring cell to be measured in the different system needs to be pre-occupied is not allowed to be used, the different system measurement unit may recalculate another time window for the current frequency point of the neighboring cell to be measured in the different system, or directly judge whether the time window that the frequency point of the neighboring cell to be measured in the different system needs to be pre-occupied is allowed to be used.
If another time window is recalculated for the frequency point of the neighboring cell to be measured of the different system, for the recalculated time window, the different system measurement unit still needs to determine whether to allow use. When use is allowed, step 14 is performed. Of course, it may also be directly determined whether the pre-occupation time window required by the frequency point of the neighboring cell to be detected of another different system is allowed to be used, and step 14 is executed when the use is allowed. The method is only required to finish judging the time windows corresponding to the frequency points of all the neighboring cells to be tested of the different systems, and finish measuring the frequency points of the neighboring cells to be tested of the different systems corresponding to the time windows which are allowed to be used.
It may be understood that when determining whether the pre-occupation time window required by the frequency point of the neighboring cell to be detected by the different system is allowed to be used, the method may be implemented based on the description of whether the pre-occupation time window required by the frequency point of the neighboring cell to be detected by the different system is allowed to be used, which is not repeated herein.
