Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.
In the prior art, for synchronization between multiple cells, one cell is usually used as a reference (usually, a currently camped serving cell), and other cells (neighboring cells) are synchronized in a manner of increasing an offset from the serving cell. In the prior art, according to the description of the communication protocol, the offset between different cells is shown in table 1:
| Cell ID | SFN Offset | FDD Tcell(Ts) |
| Cell 1 | 0 | 0 |
| Cell 2 | 124 | 30720 |
| Cell 3 | 257 | 150897 |
| Cell 4 | 1000 | 61440 |
| Cell 6 | 657 | 524 |
| Cell 10 | 129 | 43658 |
| Cell 11 | 957 | 92160 |
| Cell 12 | 1015 | 181617 |
| Cell 13 | 890 | 31244 |
| Cell 14 | 680 | 300501 |
| Cell 23 | 383 | 212337 |
TABLE 1
In table 1:
1) the Cell ID indicates a serial number of each Cell (Cell), where Cell 1 is a primary Cell (which may be a currently camped serving Cell) and other cells are neighbor cells.
2) SFN Offset represents an Offset (Offset) of a System Frame Number (System Frame Number), that is, an Offset between a System Frame of a neighboring cell and a start position of a System Frame of a serving cell. According to the offset, the mobile terminal can calculate the acquisition positions of the system frames of different neighboring cells.
3) The FDD Tcell is an offset of a synchronization channel of a cell in a Frequency Division Duplex (FDD) system (hereinafter, the offset of the cell synchronization channel is collectively referred to as an "offset").
One radio frame is 307200Ts, and occupies 10ms of data. One radio frame includes 10 subframes (subframes), each of which occupies 1ms of data, and for one radio frame, a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) are usually located in the first Subframe (Subframe 0) and the sixth Subframe (Subframe 5) of the one radio frame, so that the Subframe0 or Subframe 5 can be used to perform Synchronization operation on neighboring cells.
As can be seen from table 1, if the offsets of all neighboring cells with respect to the reference cell (which may be the currently camped serving cell) are distributed in the interval of 0-10ms (i.e. the maximum offset corresponds to an offset of one radio frame), Subframe0 may be used for synchronization, or Subframe 5 may be used for synchronization, so as to reduce the synchronization data to be acquired to the interval of 0-5 ms.
However, in the above prior art, for the multi-cell synchronous operation, about 5ms of synchronous data needs to be acquired each time, which still increases the power consumption of the mobile terminal. The technical scheme of the invention aims to further reduce the data volume of the synchronous data required to be acquired by synchronizing all the adjacent cells each time by changing the measurement and acquisition mode of the synchronous data.
Therefore, in a preferred embodiment of the present invention, a method for measuring synchronization data is provided, which is suitable for a mobile terminal. Further, in a preferred embodiment of the present invention, the above-mentioned synchronization data measurement method is applied to an FDD communication system. In a preferred embodiment of the present invention, the above-mentioned synchronous data measurement method is applied to a Long Term Evolution (LTE) communication system, that is, the method is applied to an FDD LTE communication system.
In the preferred embodiment of the present invention, a plurality of offset matching ranges are preset in the mobile terminal, and the specific functions of the offset matching ranges will be described in detail below.
As shown in fig. 1, in a preferred embodiment of the present invention, the method for measuring synchronous data specifically includes:
step S1, the mobile terminal measures the offset of cell synchronous channel between all adjacent cells and the current resident service cell;
step S2, the mobile terminal matches the offset corresponding to each adjacent cell with the offset matching range, and determines the synchronization type of the corresponding adjacent cell according to the matching result;
in a preferred embodiment of the present invention, the preset offset matching range may be set to include three types according to actual situations:
1) a first offset matching range. In a preferred embodiment of the present invention, the first offset matching range may be [0ms,1ms ] < U (4ms,5ms ]. in other words, an offset satisfying 0ms ≦ A1 ≦ 1ms, or 4ms < A2 ≦ 5ms, which means that the offset is within the first offset matching range, i.e., matches the first offset matching range.
In a preferred embodiment of the present invention, the above-mentioned a1 represents an offset measured when a sixth subframe in a radio frame is used to perform a radio frame synchronization operation on a corresponding neighboring cell based on a serving cell; i.e., a1, indicates the measured offset for the case of synchronization with Subframe 5 (as shown in fig. 2).
In a preferred embodiment of the present invention, the a2 represents an offset measured when a first subframe in a radio frame is used and a serving cell is used as a reference to perform a radio frame synchronization operation on a corresponding neighboring cell; i.e., a2, indicates the measured offset for synchronization with Subframe0 (as shown in fig. 3).
Then in a preferred embodiment of the present invention, the neighbor cells corresponding to the offsets matching the first offset matching range are classified as a first synchronization type.
2) A second offset matching range. In a preferred embodiment of the present invention, the second offset matching range may be (1ms,2ms ]. u (3ms,4 ms). in other words, an offset satisfying 1ms < A1 ≦ 2ms, or 3ms < A2 ≦ 4ms, which means that the offset is within the second offset matching range, i.e. matches the second offset matching range.
In the preferred embodiment of the present invention, a1 represents the measured offset when Subframe 5 is used for synchronization (as shown in fig. 4).
In the preferred embodiment of the present invention, a2 represents the measured offset when Subframe0 is used for synchronization (as shown in fig. 5).
Then in the preferred embodiment of the present invention, the neighbor cell corresponding to the offset matching the second offset matching range is classified as the second synchronization type.
3) A third offset matching range. In a preferred embodiment of the present invention, the third offset matching range may be (2ms,3 ms) — in other words, an offset satisfying 2ms < a1 ≦ 3ms indicates that the offset is within the third offset matching range, i.e. matches the third offset matching range.
In the preferred embodiment of the present invention, a1 represents the measured offset when Subframe 5 is used for synchronization (as shown in fig. 6).
Then in the preferred embodiment of the present invention, the neighbor cell corresponding to the offset matching the third offset matching range is classified as the third synchronization type.
In a preferred embodiment of the present invention, the preset offset matching range may be adjusted according to an actual situation, and accordingly, the determined synchronization type of the neighboring cell may also be adjusted accordingly.
Step S3, in a discontinuous reception cycle, the mobile terminal measures all neighboring cells associated with the same synchronization type to receive synchronization data associated with the synchronization type;
1) associated with the first synchronization type:
in a preferred embodiment of the present invention, as shown in fig. 2, the frame a is a radio frame of a currently camped serving cell, and is used as a reference frame for the current synchronization operation. Frames B-D are radio frames associated with different neighbor cells, respectively.
Then with Subframe 5 synchronization, it can be seen that in the case of 0ms ≦ A1 ≦ 1ms, i.e., from no offset (i.e., coinciding with reference frame A, not shown in FIG. 2) to an offset of one sub-frame (e.g., radio frame D shown in FIG. 2), the measured and received synchronization Data only needs 2ms, i.e., the received 2ms of synchronization Data encapsulates the synchronization Data associated with all neighboring cells of the first synchronization type (e.g., the synchronization Data of the Data1 segment shown in FIG. 2).
In the preferred embodiment of the present invention, as shown in fig. 3, the frame a is also a radio frame of the currently camped serving cell, and is used as the reference frame for the current synchronization operation. Frames B-D are radio frames associated with different neighbor cells, respectively.
Then in the case of using the SubFrame0 synchronization, it can be seen that in the case of 4ms < a2 ≦ 5ms, i.e., shifting from infinity close to 4 subframes (e.g., radio frame B shown in fig. 3) to 5 subframes (e.g., radio frame D shown in fig. 3), the measured and received synchronization Data only needs 2ms, i.e., receiving 2ms of synchronization Data encapsulates the synchronization Data (e.g., the synchronization Data of Data2 segment shown in fig. 3) associated with all neighboring cells of the first synchronization type.
In summary, in the case that the neighboring cell is associated with the first synchronization type, the mobile terminal only needs to receive 2ms of synchronization data to perform synchronization operation on all neighboring cells in the synchronization type.
2) Associated with the second synchronization type:
in the preferred embodiment of the present invention, as shown in fig. 4, the frame a is a radio frame of a currently camped serving cell, and is used as a reference frame for the current synchronization operation. Frames B-D are radio frames associated with different neighbor cells, respectively.
Then with Subframe 5 synchronization, it can be seen that in the case of 1ms < a1 ≦ 2ms, i.e., from infinitely close to offset by 1 Subframe (e.g., radio frame B shown in fig. 4) to offset by 2 subframes (e.g., radio frame D shown in fig. 4), the measured and received synchronization Data only needs 3ms, i.e., the reception of 3ms of synchronization Data encapsulates the synchronization Data associated with all neighbor cells of the first synchronization type (e.g., the synchronization Data of Data3 segment shown in fig. 4).
In the preferred embodiment of the present invention, as shown in fig. 5, the frame a is also a radio frame of the currently camped serving cell, and is used as the reference frame for the current synchronization operation. Frames B-D are radio frames associated with different neighbor cells, respectively.
Then in the case of using the SubFrame0 synchronization, it can be seen that in the case of 3ms < a2 ≦ 4ms, i.e., shifting from infinity close to 3 subframes (e.g., radio frame B shown in fig. 5) to 4 subframes (e.g., radio frame D shown in fig. 5), the measured and received synchronization Data only needs 3ms, i.e., the received 3ms of synchronization Data can encompass the synchronization Data of all neighboring cells associated with the second synchronization type (e.g., the synchronization Data of Data4 segment shown in fig. 5).
In summary, in the case that the neighboring cell is associated with the second synchronization type, the mobile terminal only needs to receive 3ms of synchronization data to perform synchronization operation on all neighboring cells in the synchronization type.
3) Associated with a third synchronization type:
in a preferred embodiment of the present invention, as shown in fig. 6, the frame a is a radio frame of a currently camped serving cell, and is used as a reference frame for the current synchronization operation. Frames B-D are radio frames associated with different neighbor cells, respectively.
Then with Subframe 5 synchronization, it can be seen that in the case of 2ms < a1 ≦ 3ms, i.e., from infinitely close to offset by 2 subframes (e.g., radio frame B shown in fig. 6) to offset by 3 subframes (e.g., radio frame D shown in fig. 6), the measured and received synchronization Data only needs 4ms, i.e., the reception of 4ms of synchronization Data encapsulates the synchronization Data (e.g., the synchronization Data of Data5 segment shown in fig. 6) associated with all neighbor cells of the third synchronization type.
In summary, in the case that the neighboring cell is associated with the third synchronization type, the mobile terminal only needs to receive synchronization data of 4ms to perform synchronization operation on all neighboring cells in the synchronization type.
By adopting the technical scheme of the invention, for one-time synchronous operation (namely synchronous operation), the synchronous data required to be received by the mobile terminal mostly occupies 4ms of data volume, which is smaller than the data volume occupying 5ms in the prior art.
In a preferred embodiment of the present invention, in the step S3, the mobile terminal measures and receives synchronization data of all neighboring cells associated with a synchronization type in a Discontinuous Reception (DRX) cycle, and reports all the received synchronization data in a measurement reporting cycle.
In a preferred embodiment of the present invention, taking FDD LTE communication system as an example, in FDD LTE, one DRX cycle is 320ms, and one measurement reporting cycle is 1280ms, and then 4 DRX cycles are included in one measurement reporting cycle. In a measurement reporting period, the mobile terminal respectively measures and acquires the judged synchronous data related to the adjacent cells of the same synchronous type in each DRX period, and reports all the acquired synchronous data in a unified way when the measurement reporting period is over.
In a preferred embodiment of the present invention, in the measurement reporting period, the mobile terminal measures and receives synchronization data associated with neighboring cells of different synchronization types in different discontinuous reception periods according to a preset measurement sequence.
Then, hereinafter, according to the technical solution of the present invention, a case of receiving synchronization data in different synchronization scenarios is described:
1) in the prior art, for any scenario, a mobile terminal needs to receive synchronous data of 5ms in each DRX cycle, and then in one measurement reporting cycle, the mobile terminal receives and reports 20ms of synchronous data in total.
2) In the first scenario of the present invention, all neighboring cells associated with the currently camped serving cell are neighboring cells of the first synchronization type, and in each DRX cycle, the mobile terminal only needs to receive 2ms of synchronization data, and in a measurement reporting cycle, receives and reports 8ms of synchronization data in total.
3) In the second scenario of the present invention, all neighboring cells associated with the currently camped serving cell are neighboring cells of the second synchronization type, and in each DRX cycle, the mobile terminal only needs to receive 3ms of synchronization data, and in a measurement reporting cycle, receives and reports 12ms of synchronization data in total.
4) In a third scenario of the present invention, all neighboring cells associated with the currently camped serving cell are neighboring cells of the third synchronization type, and in each DRX cycle, the mobile terminal only needs to receive 4ms of synchronization data, and in a measurement reporting cycle, receives and reports 16ms of synchronization data in total.
5) In a fourth scenario of the present invention, if some neighboring cells are determined as neighboring cells of the first synchronization type and some neighboring cells are determined as neighboring cells of the second synchronization type among all neighboring cells associated with the currently camped serving cell, that is, there are neighboring cells associated with the first synchronization type and neighboring cells associated with the second synchronization type at the same time, the mobile terminal measures and receives synchronization data of the corresponding neighboring cells in a measurement reporting period (including 4 DRX cycles) by using a preset sequence. In a preferred embodiment of the present invention, the predetermined sequence may be to take turns in different DRX cycles for measuring and receiving synchronization data of cells associated with different synchronization types, for example: within an odd number of DRX cycles, the mobile terminal measures and receives synchronization data associated with a first synchronization type of neighbor cell; the mobile terminal measures and receives synchronization data associated with a neighbor cell of the second synchronization type for an even number of DRX cycles. In other words, in this embodiment, the preset sequence may be to stagger the measurement and reception of the synchronization data of the neighbor cells of different synchronization types in consecutive DRX cycles. Finally, in a measurement reporting period, the mobile terminal receives 10ms of synchronous data in total and reports the data.
6) In a fifth scenario of the present invention, if some neighboring cells are determined as neighboring cells of the first synchronization type and some neighboring cells are determined as neighboring cells of the third synchronization type among all neighboring cells associated with the currently camped serving cell, that is, there are neighboring cells associated with the first synchronization type and neighboring cells associated with the third synchronization type at the same time, the mobile terminal measures and receives synchronization data of the corresponding neighboring cells in a measurement reporting period (including 4 DRX cycles) by using a preset sequence. In a preferred embodiment of the present invention, the preset sequence may also be the above-mentioned alternating sequence, and finally, in one measurement reporting period, the mobile terminal receives and reports the synchronization data of 12ms in total.
7) In a sixth scenario of the present invention, in all neighboring cells associated with the currently camped serving cell, if some neighboring cells are determined as neighboring cells of the second synchronization type, and some neighboring cells are determined as neighboring cells of the third synchronization type, that is, there are neighboring cells associated with the second synchronization type and neighboring cells associated with the third synchronization type at the same time, then in one measurement reporting period (including 4 DRX cycles), the mobile terminal measures and receives synchronization data of the corresponding neighboring cells in a preset sequence. In a preferred embodiment of the present invention, the preset sequence may also be the above-mentioned alternating sequence, and finally, in one measurement reporting period, the mobile terminal receives and reports the total 14ms of synchronization data.
8) In a seventh scenario of the present invention, of all neighboring cells associated with a currently camped serving cell, some neighboring cells are determined as neighboring cells of a first synchronization type, some neighboring cells are determined as neighboring cells of a second synchronization type, and some neighboring cells are determined as neighboring cells of a third synchronization type, that is, neighboring cells associated with the first synchronization type, the second synchronization type, and the third synchronization type exist at the same time, then in one measurement reporting period (including 4 DRX periods), the mobile terminal measures and receives synchronization data of corresponding neighboring cells in a preset order. In a preferred embodiment of the present invention, the predetermined sequence may be for receiving synchronization data of neighbor cells associated with different synchronization types in a continuous DRX cycle.
For example, in one measurement reporting period:
receiving synchronization data associated with a neighbor cell of a first synchronization type for a total of 2ms in a first DRX period;
subsequently receiving synchronization data associated with a neighbor cell of a second synchronization type for a total of 3ms during a second DRX cycle;
finally receiving the synchronization data of the neighbor cell associated with the third synchronization type in a third DRX period, wherein the total time is 4 ms;
during a fourth DRX cycle, continuing to receive synchronization data associated with the neighbor cell of the first synchronization type for a total of 2 ms;
in this embodiment, the total amount of synchronization data received and reported by the mobile terminal in one measurement reporting period is 11 ms.
For another example, since the mobile terminal measures and receives the synchronization data of the neighboring cell associated with the second synchronization type in the last DRX cycle in the last measurement reporting cycle, in the next measurement reporting cycle:
receiving synchronization data of a neighbor cell associated with a third synchronization type for a total of 4ms in a first DRX cycle;
subsequently receiving synchronization data associated with a neighbor cell of the first synchronization type for a total of 2ms during a second DRX cycle;
finally receiving the synchronization data of the adjacent cell related to the second synchronization type in a third DRX period, wherein the total time is 3 ms;
during a fourth DRX cycle, continuing to receive synchronization data associated with a neighbor cell of the third synchronization type for a total of 4 ms;
in this embodiment, the total amount of synchronization data received and reported by the mobile terminal in one measurement reporting period is 13 ms.
In other words, since three synchronization types are defined in total, in case of taking measurements and receiving in turn, in one measurement reporting period (including 4 DRX periods), it is certain that synchronization data of neighboring cells associated with one synchronization type is repeatedly received, and therefore, in the seventh scenario, the synchronization data measured and received by the mobile terminal in one measurement reporting period is between 11ms and 13 ms.
In summary, by adopting the technical scheme of the present invention, in any scenario, the data volume of the synchronous data measured and reported by the mobile terminal in a measurement reporting period is smaller than the data volume measured and reported in the prior art, so the working time of the mobile terminal for performing cell synchronous measurement is shortened, and the power consumption of the mobile terminal is further reduced.
In a preferred embodiment of the present invention, there is also provided a mobile terminal, wherein the above-mentioned synchronous data measurement method is adopted.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
