Step 402, base station a obtains the hysteresis relative quantity of second carrier wave according to the RSRP of this first carrier that gets access to and second carrier wave in sub-district to be measured.

Concrete, base station a is according to the RSRP of second carrier wave among RSRP, the sub-district B of first carrier among the B of sub-district, and the RSRP of the RSRP of the first carrier of at least one neighbor cell of sub-district B and second carrier wave obtains the hysteresis relative quantity.

Above-mentioned steps 402 can be passed through formula (2) and calculate.

$\mathrm{Delta}\_\mathrm{Hys}={\mathrm{RSRP}}_2^n-{\mathrm{RSRP}}_1^n+10\log \frac{\underset{\mathrm{neighbour}1}{\mathrm{\Σ}}{10}^{{\mathrm{RSRP}}_{1\_n1}/10}}{\underset{\mathrm{neighbour}2}{\mathrm{\Σ}}{10}^{{\mathrm{RSRP}}_{2\_n2}/10}}---\left(2\right)$

Wherein, Delta_Hys represents the hysteresis relative quantity of second carrier wave,

Represent the RSRP of first carrier in the target neighbor cell;

Represent the RSRP of second carrier wave in the target neighbor cell;

Represent the linear RSRP sum of first carrier at least one neighbor cell of sub-district B, this linearity RSRP sum is used for representing the interference sum of this at least one neighbor cell first carrier to target carrier;

Represent the linear RSRP sum of second carrier wave at least one neighbor cell of sub-district B, this linearity RSRP sum is used for representing the interference sum of this at least one neighbor cell second carrier wave to target carrier.

Introduce the derivation of formula in the present embodiment (2) below.Wherein, being specially hysteresis with parameter is that example describes.

If two the carrier wave first carriers and second carrier wave, its carrier frequency is respectively f1 and f2, and wherein, second carrier wave is a target carrier.The Signal to Interference plus Noise Ratio of the current business of this f1 and f2 satisfies following formula

${\mathrm{SINR}}_1^s=\frac{{10}^{({\mathrm{RSRP}}_1^n-H_1)/10}}{B_1\·{\mathrm{PSD}}_1+N_1}---\left(3\right)$

${\mathrm{SINR}}_2^s=\frac{{10}^{({\mathrm{RSRP}}_2^n-H_2)/10}}{B_2\·{\mathrm{PSD}}_2+N_2}---\left(4\right)$

Wherein

Signal to Interference plus Noise Ratio for this two carrier wave UE business in Serving cell;

By (3) and (4), can obtain:

$H_2-H_1={\mathrm{RSRP}}_2^n-{\mathrm{RSRP}}_1^n+10\log \frac{{\mathrm{SINR}}_1^s(B_1\·{\mathrm{PSD}}_1+N_1)}{{\mathrm{SINR}}_2^s(B_2\·{\mathrm{PSD}}_2+N_2)}---\left(5\right)$

Suppose:

${\mathrm{SINR}}_1^s={\mathrm{SINR}}_2^s$

Then formula (5) is

$H_2-H_1={\mathrm{RSRP}}_2^n-{\mathrm{RSRP}}_1^n+10\log \frac{B_1\·{\mathrm{PSD}}_1+N_1}{B_2\·{\mathrm{PSD}}_2+N_2}---\left(6\right)$

Wherein

Be the RSRP of first carrier at least one neighbor cell of target neighbor cell interference sum to target carrier;

Be the RSRP of second carrier wave at least one neighbor cell of target neighbor cell interference sum to target carrier; Then (7) are brought in (6), $\mathrm{Delta}\_\mathrm{Hys}=H_2-H_1={\mathrm{RSRP}}_2^n-{\mathrm{RSRP}}_1^n+10\log \frac{\underset{\mathrm{neighbour}1}{\mathrm{\Σ}}{10}^{{\mathrm{RSRP}}_{1\_n1}/10}}{\underset{\mathrm{neighbour}2}{\mathrm{\Σ}}{10}^{{\mathrm{RSRP}}_{2\_n2}/10}}---\left(2\right)$

Wherein, Delta_Hys represents the hysteresis relative quantity of second carrier wave.

By formula (2) as can be known, target carrier in hysteresis relative quantity and the target neighbor cell, that is, and second carrier wave

Second carrier wave in the target neighbor cell

The linear RSRP sum of first carrier at least one neighbor cell of target neighbor cell, and the linear RSRP sum of second carrier wave is relevant at least one neighbor cell of target neighbor cell.Wherein, linear RSRP refers to 10 ^RSRP/10

In like manner, the side-play amount Delta_Of of carrier wave particular offset also can derive out according to above-mentioned principle.

That is,

$\mathrm{Delta}\_\mathrm{Of}=H_2-H_1={\mathrm{RSRP}}_2^n-{\mathrm{RSRP}}_1^n+10\log \frac{\underset{\mathrm{neighbour}}{\mathrm{\Σ}}{10}^{{\mathrm{RSRP}}_{1\_n}/10}}{\underset{\mathrm{neighbour}}{\mathrm{\Σ}}{10}^{{\mathrm{RSRP}}_{2\_n}/10}}---\left(8\right)$

Step 403, the hysteresis that base station a obtains target carrier according to the hysteresis and the described second carrier wave hysteresis relative quantity of described first carrier, and will comprise the hysteresis of described first carrier and the message of second carrier wave (being target carrier) hysteresis sends to UE, so that make the trigger condition of UE according to the incident that enters of this first carrier and second hysteresis.

Concrete execution mode can be: establishes, and target carrier, i.e. the hysteresis Hys2 of second carrier wave, then

Hys2＝Hys1+Delta_Hys (9)

Base station a calculates Hys2 according to formula (9), and the RRC message that will comprise this Hys2 and Hys1 sends to UE.

In the present embodiment, the executive mode of this step 403 can also for: base station a sends to UE with the hysteresis of first carrier and the hysteresis relative quantity of second carrier wave, so that described UE obtains the hysteresis of second carrier wave according to the hysteresis relative quantity of the hysteresis of first carrier and second carrier wave.

Concrete executive mode can be: the RRC message that base station a will comprise Hys1 and Delta_Hys sends to UE, after UE receives this RRC message, can calculate the hysteresis of second carrier wave according to formula (9).

Need to prove, when at the number of the carrier wave of Target cell polymerization greater than 2 the time, for example, when also existing carrier frequency to be the carrier wave 3 of f3, the acquisition methods of the hysteresis of this carrier wave 3, with the number of the carrier wave of polymerization be 2 o'clock identical, promptly, carrier wave 3 as target carrier, is obtained the hysteresis of carrier wave 3 according to the hysteresis of hysteresis relative quantity and first carrier (or second carrier wave).That is, as target carrier, utilize formula (9) to calculate and to obtain each carrier wave with the hysteresis of the carrier wave of a certain polymerization and the hysteresis relative quantity of this target carrier.

In addition, in another embodiment of the present invention, specifically combine when parameter is the carrier frequency particular offset, network side is at the method for the carrier frequency particular offset of target carrier configuration, provide in the concrete executive mode of this method and the present embodiment when parameter is hysteresis, the carrier frequency particular offset can be carried out as hysteresis.Concrete implementation is that those skilled in the art can obtain easily according to the description of foregoing, not redundant here the narration.

Be that hysteresis is that example is described with the parameter in the present embodiment, in fact, the trigger condition of some incident is both to be subjected to hysteresis, also be subjected to the influence of carrier frequency particular offset, at this moment, can make the target carrier configuration enter trigger event by the configuration hysteresis, also can make the target carrier configuration enter trigger event by configuration carrier frequency particular offset, when the conditional inquality of Event triggered is subjected to hysteresis and carrier frequency particular offset simultaneously and influences, also can make the target carrier configuration enter trigger event by configuration hysteresis and carrier frequency particular offset simultaneously, when disposing simultaneously, two parameters can be regarded as a parameter and carry out.That is: can regard the carrier frequency particular offset as hysteresis, or regard hysteresis as the carrier frequency particular offset and carry out.

The method of present embodiment provides under state of carrier aggregation, and network side is the scheme that the UE configuration enters the parameter of trigger event condition.And, all be configured to identical numerical value if considered hysteresis in the present embodiment with other carrier waves, promptly all carrier waves can use identical hysteresis, to produce because the signal strength signal intensity of different carrier, interference strength, load condition, the UE position is different with UE movement velocity etc., it is asynchronous reporting of each carrier wave measurement result to occur, the problem that causes the RRM performance to reduce thus, therefore in the present embodiment, adopted the technical scheme of obtaining the parameter of target carrier according to the parameter relative quantity, by the corrected parameter relative quantity, make UE can be as much as possible under the situation of multicarrier the measurement result of each carrier channel information be reported to network side simultaneously, make network when carrying out switching, can know the channel information behind current each carrier wave updating, obtain and to have improved RRM judgement accuracy, the technique effect that handover success rate increases.

Embodiment 5

This tabulation can also be upgraded according to the variation of the actual carrier aggregation configuration of network factors such as (polymerization wave band, aggregate bandwidths), so that provide accurate amount higher numerical value all the time according to different time granularities.This tabulation part can be with reference to as following table one:

Table one

Wherein, M represents the combined information of polymerization carrier wave, and f represents carrier frequency, and B represents bandwidth, and Δ is represented the hysteresis relative quantity.Corresponding different f represents different carrier waves respectively.

The parameter of the combined information of the polymerization carrier wave that table one lists and the parameter of aggregate bandwidth are that the base station can be known, and also can increase other parameter as required in the tabulation, for example: the translational speed of UE, network topologies etc. are so that improve the accuracy of the hysteresis relative quantity of obtaining from this tabulation.Need to prove that table one has only been enumerated the part of actual default tabulation, the content of other parts is that one skilled in the art know by inference easily according to the content that has listed of table one, has not here just enumerated one by one.

After using table one, under the multicarrier situation, show that for uniting the first carrier and second carrier wave that service is provided for UE, the flow process of obtaining the hysteresis of second carrier wave comprises as Fig. 6:

Step 501, base station are obtained the hysteresis Hys1 of first carrier in the Serving cell multicarrier.

Step 502, base station are tabled look-up according to the aggregate bandwidth of combined information, first carrier and second carrier wave of the polymerization carrier wave of the current first carrier and second carrier wave at least and are obtained the hysteresis relative quantity Delta_Hys of the second corresponding carrier wave.

Concrete, be example with table one.The carrier frequency of first carrier is f1, and the carrier frequency of second carrier wave is f2, and the combined information of the polymerization carrier wave of f1 and f2 is M1, and the aggregate bandwidth of f1 and f2 is B2, and according to the content of enumerating in the table one, can find corresponding hysteresis relative quantity is Δ 2.

Step 503, the base station obtains the hysteresis of this second carrier wave according to the hysteresis of this first carrier and the hysteresis relative quantity that finds, if the hysteresis of this second carrier wave is Hys2, and will comprise the hysteresis of described first carrier and the message of the second carrier wave hysteresis sends to UE.

The concrete mode of obtaining Hys2 can calculate by formula (9), and the RRC message that will comprise this Hys2 and Hys1 sends to UE.

In the present embodiment, the executive mode of this step 503 can also for: the base station sends to UE with the hysteresis of first carrier and the hysteresis relative quantity of second carrier wave, so that described UE obtains the hysteresis of second carrier wave according to the hysteresis relative quantity of the hysteresis of first carrier and second carrier wave.

Concrete executive mode can be: the RRC message that the base station will comprise Hys1 and Δ 2 sends to UE, after UE receives this RRC message, can calculate the hysteresis of second carrier wave according to formula (9).

Need to prove, when parameter is the carrier frequency particular offset, still can set up the tabulation of a similar above-mentioned table one, thereby and can obtain the carrier frequency particular offset of second carrier wave in the polymerization carrier wave equally by the relative quantity of visiting the carrier frequency particular offset in this tabulation.The concrete implementation when parameter is hysteresis that provides in concrete executive mode and the present embodiment is similar, is that those skilled in the art can obtain easily according to the description of foregoing, not redundant here the narration.

Present embodiment specifically provides under state of carrier aggregation, and by visiting the mode of the tabulation of setting up in advance, making network side is the scheme that the UE configuration enters the parameter of trigger event condition.And the scheme of the parameter relative quantity that gets access to by tabling look-up can reduce the amount of calculation of network side or UE, has improved network side provides parameter for multicarrier efficient.
