Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a parameter configuration method, an apparatus, and a multi-carrier system.
Background
Radio Resource Management (RRM) is one of the important functions in a Radio access system, and both handover and power control are used to the RRM. Good RRM can greatly improve the spectral efficiency and throughput of the system. In order to support the RRM function effectively, it is necessary that a User Equipment (UE) can feed back the measurement result of the channel information to the network side in time so as to support the implementation of the RRM function.
In the prior art, one UE uses only one carrier, a base station sends a corresponding parameter configured for the carrier by a network side to the UE through a Radio Resource Controller (RRC) measurement message, and the UE determines whether a condition for triggering an event is satisfied according to the parameter, and if so, enters the corresponding event, performs corresponding measurement and reports a measurement result to the network side. Therefore, the performance of reporting the measurement result when the UE enters the trigger event will affect the RRM function and thus the overall performance of the network.
The trigger events may include a1, a2, A3, a4, a5, and B1 and B2, among others. The triggering of each event is affected by a number of parameters, including: hysteresis values and various offsets.
For example: entry condition for B1 event
Mn+Ofn-Hys＞Thresh (1)
Where Mn is the UE measurement result for the neighbor cell, Hys is the hysteresis value for this event, Ofn is the carrier frequency specific offset of the neighbor cell, Thresh is the threshold for the B1 event. The UE determines whether the above expression (1) is satisfied based on the received Hys, Ofn and measured Mn, and if so, enters the event B1. Wherein the hysteresis value Hys, as well as the carrier frequency specific offset Ofn, may affect the entry of the B1 event.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art: the prior art solution only addresses the scenario when the UE uses one carrier, and in the carrier aggregation technology proposed in the industry, in the case that one UE can use multiple carriers, the prior art does not provide a corresponding solution.

Specifically, the base station a acquires the relative hysteresis value according to the RSRP of the first carrier in the cell B, the RSRP of the second carrier in the cell B, the RSRP of the first carrier of at least one neighboring cell of the cell B, and the RSRP of the second carrier.
The above step 402 can be calculated by equation (2).
Wherein Delta _ Hys represents the hysteresis value relative quantity of the second carrier,
RSRP representative of a first carrier in the target neighbor cell;
RSRP representative of a second carrier in the target neighbor cell;
the sum of the linear RSRPs of the first carrier in at least one adjacent cell representing the cell B is used for representing the sum of the interference of the first carrier in the at least one adjacent cell to the target carrier;
and the sum of the linear RSRPs of the second carrier in at least one adjacent cell representing the cell B is used for representing the sum of the interference of the second carrier in the at least one adjacent cell to the target carrier.
The derivation process of formula (2) in this embodiment is described below. The following description will be given by taking a parameter, specifically, a hysteresis value, as an example.
Two carriers, a first carrier and a second carrier, are provided, with carrier frequencies f1 and f2, respectively, wherein the second carrier is a target carrier. The SINR of the current service of f1 and f2 satisfies the following formula

N is a radical of1、N2Is the thermal noise power of the two carriers.
From (3) and (4), it is possible to obtain:
suppose that:
then the formula (5) is
Because of this, it is possible to reduce the number of the,
wherein
The sum of the interference of the RSRP of the first carrier wave in at least one adjacent cell of the target adjacent cell to the target carrier wave;
the sum of the interference of the RSRP of the second carrier wave in at least one adjacent cell of the target adjacent cell to the target carrier wave; then (7) is brought into (6) to obtain <math><mrow><mi>Delta</mi><mo>_</mo><mi>Hys</mi><mo>=</mo><msub><mi>H</mi><mn>2</mn></msub><mo>-</mo><msub><mi>H</mi><mn>1</mn></msub><mo>=</mo><msubsup><mi>RSRP</mi><mn>2</mn><mi>n</mi></msubsup><mo>-</mo><msubsup><mi>RSRP</mi><mn>1</mn><mi>n</mi></msubsup><mo>+</mo><mn>10</mn><mi>log</mi><mfrac><mrow><munder><mi>Σ</mi><mrow><mi>neighbour</mi><mn>1</mn></mrow></munder><msup><mn>10</mn><mrow><msub><mi>RSRP</mi><mrow><mn>1</mn><mo>_</mo><mi>n</mi><mn>1</mn></mrow></msub><mo>/</mo><mn>10</mn></mrow></msup></mrow><mrow><munder><mi>Σ</mi><mrow><mi>neighbour</mi><mn>2</mn></mrow></munder><msup><mn>10</mn><mrow><msub><mi>RSRP</mi><mrow><mn>2</mn><mo>_</mo><mi>n</mi><mn>2</mn></mrow></msub><mo>/</mo><mn>10</mn></mrow></msup></mrow></mfrac><mo>-</mo><mo>-</mo><mo>-</mo><mrow><mo>(</mo><mn>2</mn><mo>)</mo></mrow></mrow></math>
Wherein Delta _ Hys represents the hysteresis value relative quantity of the second carrier.
As can be seen from equation (2), the hysteresis value is related to the target carrier in the target neighboring cell, i.e., the second carrier
Of a second carrier in a target neighbouring cell
The sum of the linear RSRPs of the first carrier in the at least one of the target neighbor cells and the sum of the linear RSRPs of the second carrier in the at least one of the target neighbor cells are related. Wherein linear RSRP is 10RSRP/10。
Similarly, the offset Delta _ Of the carrier specific offset can also be derived according to the above-mentioned principle.
That is to say that the first and second electrodes,
The specific implementation mode can be as follows: if the hysteresis value Hys2 of the target carrier, i.e. the second carrier, is set, then
Hys2＝Hys1+Delta_Hys (9)
The base station a calculates Hys2 according to equation (9), and transmits an RRC message containing the Hys2 and Hys1 to the UE.
In this embodiment, the execution manner of step 403 may also be: and the base station a sends the hysteresis value of the first carrier and the hysteresis value relative quantity of the second carrier to the UE, so that the UE acquires the hysteresis value of the second carrier according to the hysteresis value of the first carrier and the hysteresis value relative quantity of the second carrier.
The specific execution mode can be as follows: the base station a sends an RRC message containing Hys1 and Delta _ Hys to the UE, and after receiving the RRC message, the UE can calculate the hysteresis value of the second carrier according to formula (9).
When the number of carriers aggregated in the target cell is greater than 2, for example, when there is a carrier 3 with a carrier frequency of f3, the hysteresis value of the carrier 3 is obtained by the same method as when the number of aggregated carriers is 2, that is, the hysteresis value of the carrier 3 is obtained from the hysteresis value of the first carrier (or the second carrier) and the relative amount of the hysteresis value, using the carrier 3 as the target carrier. That is, each carrier is used as a target carrier, and the hysteresis value of a carrier aggregated with a certain carrier and the relative amount of the hysteresis value of the target carrier can be obtained by calculating using equation (9).
In addition, in another embodiment of the present invention, a method for configuring, by a network side, a carrier frequency specific offset for a target carrier when a parameter is the carrier frequency specific offset is specifically combined, and a specific implementation manner of the method is similar to that provided in this embodiment, and when the parameter is a hysteresis value, the carrier frequency specific offset can be implemented as the hysteresis value. The specific implementation procedures are easily obtained by those skilled in the art according to the above description, and are not redundantly described here.
In this embodiment, a parameter is taken as an example to describe a hysteresis value, and actually, trigger conditions of some events are affected by both the hysteresis value and a carrier frequency specific offset, at this time, a target carrier configuration may enter a trigger event by configuring the hysteresis value, or a target carrier configuration may enter the trigger event by configuring the carrier frequency specific offset, when a condition inequality triggered by an event is affected by both the hysteresis value and the carrier frequency specific offset, a target carrier configuration may enter the trigger event by configuring the hysteresis value and the carrier frequency specific offset, and when the condition inequality triggered by the event is configured simultaneously, the two parameters may be regarded as one parameter to be executed. Namely: the carrier frequency specific offset can be considered as a hysteresis value or performed as a carrier frequency specific offset.
The method of this embodiment provides a scheme for configuring, by the network side, parameters for entering a trigger event condition for the UE under the condition of carrier aggregation. Moreover, in this embodiment, it is considered that if the hysteresis values of other carriers are configured to be the same value, that is, all carriers may use the same hysteresis value, and the problem of RRM performance reduction is caused because reporting of measurement results of each carrier is asynchronous due to different signal strengths, interference strengths, load states, UE positions, UE movement speeds, and the like of different carriers, therefore, in this embodiment, a technical scheme of obtaining parameters of a target carrier according to relative amounts of the parameters is adopted, and by correcting the relative amounts of the parameters, the UE can report the measurement results of channel information of each carrier to a network side as much as possible under the condition of multiple carriers, so that the network can know updated channel information of each current carrier when performing handover, and a technical effect of improving RRM decision accuracy and increasing a handover success rate is obtained.
Example 5
This embodiment provides a method for configuring parameters, taking the parameters of the entry triggering event configured for the UE by the network side as hysteresis values. In an actual network, hysteresis values of different carriers are different according to different combination information of aggregated carriers and also different according to different aggregation bandwidths. After the network deployment is completed, RSRP of the carriers may be obtained through field test, so as to obtain the hysteresis value relative quantity of the multiple carriers, and the specific method for obtaining the hysteresis value relative quantity of each carrier may be performed according to the specific manner in step 402 in embodiment 4. That is, the process proceeds as step 402 with each carrier as a target carrier. Finally, a carrier parameter relative quantity comparison table is formed, and the carrier parameter relative quantity comparison table is a list at least comprising the combination information of the aggregated carriers, the bandwidth of the aggregated carriers and the relative quantity of the hysteresis values. The list is preset in the base station, so that the base station refers to the list when acquiring the hysteresis value relative quantity of a certain aggregated carrier.
The list can also be updated according to different time granularities and according to the change of factors such as the actual carrier aggregation configuration (aggregation wave band, aggregation bandwidth) of the network and the like, so as to provide a numerical value with higher accurate quantity all the time. Part of this list may be referred to as the following table one:
watch 1
Wherein, M represents the combination information of the aggregated carriers, f represents the carrier frequency, B represents the bandwidth, and Δ represents the relative amount of the hysteresis value. Corresponding to different f, different carriers are represented respectively.
The parameters of the combined information of the aggregated carriers and the parameters of the aggregated bandwidth listed in the table are known by the base station, and other parameters may be added to the table as needed, for example: the speed of movement of the UE, the network topology, etc., in order to improve the accuracy of the relative amount of hysteresis values obtained from the list. It should be noted that, the first table only lists a part of the list actually preset, and the contents of other parts are easily deduced by those skilled in the art according to the listed contents of the first table, and are not listed here.
After using the table one, in the case of multiple carriers, as shown in fig. 6, for a first carrier and a second carrier that can jointly provide service for a UE, the process of obtaining a hysteresis value of the second carrier includes:
in step 501, the base station obtains a hysteresis value Hys1 of a first carrier in a serving cell multi-carrier.
Specifically, take table one as an example. The carrier frequency of the first carrier is f1, the carrier frequency of the second carrier is f2, the combination information of the aggregated carriers of f1 and f2 is M1, the aggregated bandwidths of f1 and f2 are B2, and according to the contents listed in table one, the corresponding relative amount of the hysteresis value is found to be Δ 2.
The specific manner of acquiring Hys2 can be calculated by formula (9), and the RRC message including Hys2 and Hys1 is transmitted to the UE.
In this embodiment, the execution manner of step 503 may also be: and the base station sends the hysteresis value of the first carrier and the hysteresis value relative quantity of the second carrier to the UE, so that the UE acquires the hysteresis value of the second carrier according to the hysteresis value of the first carrier and the hysteresis value relative quantity of the second carrier.
The specific execution mode can be as follows: the base station sends an RRC message containing Hys1 and Δ 2 to the UE, and after receiving the RRC message, the UE may calculate the hysteresis value of the second carrier according to equation (9).
It should be noted that when the parameter is carrier frequency specific offset, a list similar to table one above may still be established, and the carrier frequency specific offset of the second carrier in the aggregated carrier may also be obtained by accessing the relative amount of the carrier frequency specific offset in the list. The specific implementation manner is similar to the specific implementation procedure provided in this embodiment when the parameter is the hysteresis value, and can be easily obtained by those skilled in the art according to the description above, and is not redundantly described here.
The present embodiment specifically provides a scheme for configuring, by accessing a pre-established list, a parameter entering a trigger event condition for a UE on a network side under a carrier aggregation condition. And the calculation amount of the network side or the UE can be reduced by the scheme of obtaining the relative amount of the parameters through table lookup, and the efficiency of providing the parameters for the multi-carrier by the network side is improved.
