Abstract
The invention relates to the communication field, and discloses a method and device for adjusting distribution positions of frequency-domain resources, so as to ensure signal quality of a terminal when an uplink transmission is performed based on discontinuous frequency-domain resources. The method comprises the following steps: in a case that the uplink transmission is performed by using discontinuous frequency-domain resources in an LTE-A (long term evolution-advanced) system, a terminal can obtain a corresponding largest frequency-domain interval according to a network-environment-based MPR (multiple protocol router) threshold value; and then based on the largest frequency-domain interval, the distribution positions of discontinuous frequency-domain resources used by the terminal are adjusted, so as to ensure the interval between each frequency-domain resource not to exceed the determined largest frequency-domain interval. Therefore, when signals are transmitted on the adjusted discontinuous frequency-domain resources, out-of-band emission due to inter-modulation (IMD) generated between each frequency-domain resource is effectively reduced, and thus the transmission quality of uplink signals are ensured, so that adverse effects to system coexistence and system performance are avoided while gain for user performance brought by the discontinuous frequency-domain transmission is fully used.
Description
Technical field
The present invention relates to the communications field, particularly a kind of method and device of adjusting the frequency domain resource distributing position.
Background technology
In the LTE system based on the Rel-8 agreement, uplink is a localized transmission.For example, consult shown in Figure 1ly, so-called localized transmission promptly is meant; Transmit upward signal at the synchronization terminal one section continuous frequency domain resource; Wherein, up PUSCH (Physical Uplink Shared Channel) and PUCCH (Physical Uplink Control Channel) are the time-divisions, promptly in same subframe, do not transmit.
And in the LTE-A system, allow on discrete frequency domain resource, to carry out uplink.Consult shown in Figure 2, can on discrete frequency domain resource, carry out under following 3 kinds of situation uplink:
1) PUSCH and PUCCH transmit simultaneously.Be that PUSCH and PUCCH possibly send at synchronization, owing to the two frequency domain resource position disperses to realize the uplink on the discontinuous frequency domain resource.
2) many bunches of transmission of PUSCH.Be to comprise discrete a plurality of bunches in the frequency domain resource, when carrying out transfer of data, according to a plurality of bunches that the divide uplink that realize on the discontinuous frequency domain resource through PUSCH.
3) up-link carrier aggregation transmission.The LTE-A system supports carrier aggregation technology, is carried out transfer of data simultaneously by a plurality of member carriers of polymerization, and from overall aggregate bandwidth, its frequency domain resource also might be discontinuous.
In the practical application; Because the transmitter radio-frequency channel is non-linear; Thereby can cause spectral re-growth to produce intermodulation product (being mainly 3 rank intermodulation products) when on discrete frequency domain resource, carrying out uplink; Consult shown in Figure 3ly, different according to the deployment position of each frequency domain resource, the position of the intermodulation product of its generation is also different.
As shown in Figure 3, two up-link carrier CC1 and CC2 combination are supposed to have carried among the CC1 and have been carried two discrete frequency domain resource F3 and F4 among two discrete frequency domain resource F1 and F2, the CC2; F1 and F4 are in band edge; Frequency bandwidth between the two is 40MHz, wherein, supposes to send PUCCH in the position of the F4 of the F1 of CC1 and CC2; Simultaneously in the position of the F3 of the F2 of CC1 and CC2, scheduling part frequency domain resource is transmitted PUSCH.When on discrete frequency domain resource, carrying out uplink, the intermodulation product that produces between the each several part frequency domain resource is various, and is as shown in Figure 3, and various intermodulation products can be divided into because of its position:
1, band internal leakage; In this case, intermodulation product mainly drops in the frequency band; For example, the IMD 2f2-f1 shown in Fig. 3
2, band external leakage: in this case, intermodulation product mainly drops in the out-of-band adjacent channel; For example, the IMD 2f1-f4 shown in Fig. 3, IMD 2f1-f2 and IMD 2f2-f3.
3, spuious leakage: in this case, intermodulation product mainly drops in the outer channel far away of frequency band.
As shown in Figure 3; Being explained as follows of various technical terms: PSD (Power Spectral Density; Power spectral density), IMD (Inter-modulation, intermodulation product), Spurious Emission (spuious leakage), Out ofband emission (band external leakage), Transmission BW (transmission bandwidth), Aggregated BW (aggregate bandwidth), BW (bandwidth, bandwidth), CC (component carrier; Member carrier) LO (local oscillator, intermediate frequency).
Obviously owing on discrete frequency domain resource, carrying out the intermodulation product that uplink produces, can produce interference to the uplink signal at terminal, thereby influence the signal quality at terminal, and influence the performance of system and the coexistence between the different systems system.
In order to address the above problem, in the embodiment of the invention, adopted following dual mode to solve:
Scheme 1: the qualification uplink is a centralized solution, does not allow.When carrying out uplink on discrete frequency domain resource;
Yet employing scheme 1 has limited the uplink mode, can't realize the flexible dispatching of network, and can't be that system brings certain performance gain through the uplink on the discontinuous frequency domain resource under the part scene.
Scheme 2: allow on discrete frequency domain resource, to carry out uplink, RF index is satisfied through MPR (back-off mechanism) in the terminal, thereby ensures signal quality.
Though employing scheme 2 does not add any restriction to the frequency domain resource occupation mode of uplink, owing to allow to carry out uplink based on discontinuous frequency domain resource; Therefore; Increased the flexibility of frequency domain resource scheduling, under various scenes, if make terminal pins that the each several part frequency domain resource is confirmed concrete MPR respectively; Can increase the implementation complexity at terminal, reduce terminal capabilities; Further, if too high MPR has been formulated at the terminal, also can influence the signal quality at terminal.

Embodiment
In the LTE-A system; Be in the terminal of sub-district diverse location; Its path loss is different, and the back-off value that therefore allows is also different, based on different power rollback value; Through the transmission of flexible dispatching distributed frequency domain, can bring gain to a certain degree at aspects such as systematic function, spectrum efficiency, dispatching flexibilities.
Carrying out the uplink meeting based on discontinuous frequency domain resource causes transmitted power to disperse to concentrate in the frequency domain resource of several sections; The resource class that the each several part frequency domain resource comprises can be provided with in advance; For example; Can comprise the PRB (Physical Resource Block) of some numbers, the position of this two parts frequency domain resource and interval are between the two depended in the position of the frequency domain intermodulation product that produces between any two-part frequency domain resource and influence.
In the practical application, if the intermodulation product that produces between the frequency domain resource of any two parts is the band internal leakage, then because the uplink signal is a quadrature, intermodulation product is less to the influence of uplink signal so, can ignore.If the intermodulation product that produces between the frequency domain resource of any two parts is spuious leakage, then,, influence also little just adopt filter to suppress so because this intermodulation product mainly is the high order modulation product that drops on the outer channel far away of frequency band.And if the intermodulation product that produces between the frequency domain resource of any two parts is the band external leakage, then intermodulation product mainly is the 3 rank intermodulation products that drop on the outer adjacent channel of frequency band, and intermodulation product is also maximum to the influence of uplink signal so; For example, worst scene is for being deployed in two-part frequency domain resource respectively the edge of aggregate bandwidth, and at this moment, the MPR value of the uplink signal transmission power that the terminal is selected is maximum, and so, intermodulation product is also obvious to the influence of uplink signal.
Because inevitably therefore the generation of intermodulation product is; In the embodiment of the invention; In order to guarantee the uplink quality of signals; Need make the intermodulation product that produces between the each several part frequency domain resource drop in the frequency band as far as possible with out-of-band spuious leakage scope in, thereby farthest reduce the influence that intermodulation product causes the uplink signal, the system that guarantees simultaneously can obtain the performance gain that the discontinuous transmission of up frequency domain brings.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
In the embodiment of the invention, the mapping relations between these three kinds of parameters of frequency domain interval, frequency domain resource size and frequency domain resource original position and the MPR need be set at first, can set up an allocation list according to certain granularity, for example: it is as shown in table 1,
Table 1
As shown in table 1, supposing the system has disposed two and has disperseed frequency domain resource, its frequency domain original position k
L-startBe 20RB, transfer resource size j
Trans-BWBe 80RB, simultaneously can confirm that according to system configuration the maximum MPR value that the current path loss allows is 7dB, can know the maximum frequency domain interval of current permission through look-up table 1, as shown in table 1, at first definite known k
L-start, j
Trans-BWCan correspond to first row of table 1; Can know according to the first row content recorded again if the MPR value is no more than 7dB's; Then maximum frequency domain interval is 100RB, promptly need guarantee to disperse the largest interval between the frequency domain resource to be no more than 100RB through system call, and the frequency domain interval between the frequency domain resource of two dispersions is more little; Its leakage is more little; So through each contents in table in the table 1 reasonably is set,, can avoid effectively producing the band external leakage between the frequency domain resource of two dispersions through the setting of maximum frequency domain interval.
Based on above-mentioned allocation list, to consult shown in Figure 4ly, in the embodiment of the invention, the flow chart of terminal adjustment frequency domain resource distributing position is following:
Step 400: the terminal Network Environment is confirmed local MPR threshold value, is called MPR
Threshould
In the practical application, when execution in step 400, following mode can be adopted in the terminal:
Confirm should path loss allowing the maximum MPR value of setting earlier according to current path loss; Be called
wherein; Current path loss can obtain according to the measurement to channel, and
can adopt the power conversion principle to obtain based on current path loss.
Then,, confirm the institute of should the user gaining is allowed the maximum MPR value of setting, be called MPR according to preset user performance gain
UE, wherein, MPR
UECan gain based on preset user and adopt the system emulation mode to confirm.
Step 410: the terminal according to the obtained
gain should be
set maximum frequency domain interval.
In the embodiment of the invention; When execution in step 410; The terminal need combine original position, the frequency domain resource size of the current discrete frequency domain resource that is assigned to according to
that obtain; According to the mapping relations of table 1 record, confirm corresponding maximum frequency domain interval again.
Step 420: the terminal is according to the maximum frequency domain interval that obtains, to this terminal distribution to the distributing position of frequency domain resource adjust, make the frequency domain interval between each frequency domain resource be no more than above-mentioned maximum frequency domain interval.
Certainly, also need be according to the frequency domain resource of the frequency domain resource size that obtains in new distributing position configuration respective numbers, the subsequent implementation example is all like this, will repeat no more.
In the practical application, according to the difference of applied environment, the executive mode of step 420 is also different, makes further in the face of the various executive modes of step 420 down and introducing in detail.
Under first kind of situation, PUSCH and PUCCH uplink single-carrier are bound transmission.
Consult shown in Figure 5ly, the frequency domain resource of carrying PUCCH is in band edge, and the frequency domain resource of carrying PUSCH is arranged in the position 1 and position 2 of frequency band, is confirming that PUCCH and PUSCH transmit the MPR that will satisfy
Threshould, and obtain corresponding peak frequency and (be called at interval
) after; The frequency domain resource of carrying PUSCH is adjusted to position 1 ' by position 1 respectively, is adjusted to position 2 ' by position 2, like this; Just can guarantee that the frequency domain resource of carrying PUSCH binds together with the frequency domain resource of carrying PUCCH; And both frequency domain interval remain on (promptly being no more than definite maximum frequency domain interval) in the permitted maximum range, further, when terminal pins to the frequency domain resource of carrying PUCCH between time slot during frequency hopping; The frequency domain that also needs simultaneously to carry PUSCH is made corresponding frequency hopping, to keep frequency domain interval between the two.
Further; When band segment is had relatively high expectations for the uplink quality of signals; Still in the time of can't satisfying instructions for use after the frequency domain interval according to aforesaid way adjustment PUSCH, PUCCH, can adopt the Rel-8 pattern, be about to PUSCH and PUCCH and carry out the time-division transmission.
Under second kind of situation, many bunches of transmission of PUSCH uplink single-carrier.
Consult shown in Figure 6; Discrete frequency domain resource (being a plurality of bunches) transmission through marking off in the whole aggregate bandwidth of PUSCH at single up-link carrier; Each bunch can be positioned at same carrier wave; Also can be between different carrier), being positioned at same carrier wave with each bunch is example, at the MPR that confirms that the PUSCH transmission will be satisfied
Threshould, and obtain corresponding peak frequency and (be called at interval
) after, a plurality of bunches the position of carrying PUSCH is adjusted according to maximum frequency domain interval, make the frequency domain interval between a plurality of bunches be no more than definite maximum frequency domain interval.For example, as shown in Figure 6, the position of bunch #2 is moved, the frequency domain interval between bunch #2 and bunch #1 is adjusted into definite maximum frequency domain interval.Because the size of band external leakage is and the frequency domain resource original position of disperseing, frequency domain resource size, and frequency domain interval is relevant, therefore, the frequency domain interval between the each several part frequency domain resource is more little, and its band external leakage is also just more little, and the MPR that needs is also just more little.
Further; When band segment is had relatively high expectations for the uplink quality of signals; Carry according to aforesaid way adjustment in the time of still can't satisfying instructions for use after the frequency domain interval between a plurality of bunches of PUSCH, can adopt the Rel-8 pattern, promptly adopt centralized fashion transmission PUSCH.
Under the third situation, many bunches of transmission of the up multicarrier of PUSCH.
As noted earlier, in PUSCH when transmission, carried out in a plurality of up-link carrier polymerizations simultaneously, and PUSCH possibly be (be included in the carrier wave and stride between the carrier wave) that is divided into a plurality of frequency domain resource (being a plurality of bunches) transmission in whole aggregate bandwidth; Scene for a plurality of up-link carriers carry out the PUSCH transmission simultaneously, adopt following scheme:
Confirming that up-link carrier carries out the MPR that the PUSCH transmission will be satisfied
Threshould, and obtain corresponding peak frequency and (be called at interval
) after, a plurality of bunches position on the up-link carrier is adjusted according to maximum frequency domain interval, make the frequency domain interval between a plurality of bunches be no more than definite maximum frequency domain interval.
For example, consult shown in Fig. 7 A, supposing currently has 4 bunches, frequency domain resource original position k
L-startBe 20RB, frequency domain resource size j
Trans-BWBe 80RB, MPR
ThreshouldBe 7dB; Then can know that according to table 1 corresponding maximum frequency domain interval is 100RB, at this moment, can make itself and the frequency domain interval between bunch 1 be no more than 100RB through the position of adjustment bunches 4; Like this; Can make full use of the user performance gain that discrete frequency domain transmission brings, also guarantee that its band external leakage is less simultaneously, promptly can not influence coexistence of systems and systematic function.
Be different from aforesaid way, confirming that up-link carrier carries out the MPR that the PUSCH transmission will be satisfied
Threshould, and obtain corresponding peak frequency and (be called at interval
) after, a plurality of bunches the number that also can disperse through adjustment, the frequency domain resource number in increasing single bunch, the frequency domain resource that comprises in being about to specify bunch is dispensed in other bunches, makes the frequency domain interval between other bunches be no more than definite maximum transmitted interval.For example, consult shown in Fig. 7 B, supposing currently has 4 bunches, frequency domain resource original position k
L-startBe 20RB, frequency domain resource size j
Trans-BWBe 80RB, MPR
ThreshouldBe 7dB, then can know that according to table 1 corresponding maximum frequency domain interval is 100RB, at this moment; The frequency domain resource that comprises in bunches 4 is dispensed in other bunches (for example, is dispensed among bunch #2 and bunch #3) order bunch #1 and adjusted bunch of #2; And the frequency domain interval between bunch #1 and the adjusted bunch of #3 all is no more than maximum transmitted at interval, i.e. 100RB, like this; Can make the frequency domain interval between each bunch remain in the maximum magnitude of permission; Thereby when making full use of the user performance gain that the transmission of discrete frequency domain brings, also reduced the band external leakage effectively, promptly can not influence coexistence of systems and systematic function.In order to realize optimum implementation effect, preferable, should be with bunch frequency domain resource that comprises at the edge of frequency band, be dispensed in the middle of the frequency band bunch among.
Further; When band segment is had relatively high expectations for the uplink quality of signals, according to still can't satisfy instructions for use behind the interval between the aforesaid way adjustment each several part frequency domain resource time, as; The MPR value is too high; Can't satisfy system performance gain, then can adopt the Rel-8 pattern, promptly adopt centralized fashion to carry out the PUSCH uplink.
Under the 4th kind of situation, the up multi-carrier transmission of PUCCH.
Consult shown in Figure 8ly, suppose to occur the scene that up-link carrier transmits PUCCH simultaneously, the PUCCH transmission mainly is lower limb transmission on the frequency band of carrier wave; For example, on two carrier waves (being called CC1 and CC2), at the lower sideband of CC1 and the upper sideband transmission PUCCH of CC2; The two interval maximum is approximately equal to aggregate bandwidth, and at this moment, the band external leakage that intermodulation product caused that produces between the two is maximum; Have a strong impact on coexistence of systems; Worsen systematic function, at this moment, the solution that can adopt comprises but is not limited to following several kinds:
At the MPR that confirms that the up-link carrier transmission will be satisfied
Threshould, and obtain corresponding peak frequency and (be called at interval
) back:
1, if confirms maximum frequency domain interval>=BW
CA/ N, wherein, BW
CABe aggregate bandwidth, N is the up-link carrier number when pre-polymerization, then in order to guarantee that each up-link carrier can transmit PUCCH simultaneously, can the position of the frequency domain resource of carrying PUCCH be adjusted to the upper sideband or the lower sideband of each up-link carrier;
For example, suppose N=2, consult shown in Figure 8ly that on CC1 and CC2, PUCCH can transmission on position 1 simultaneously, perhaps transmission on position 2 simultaneously.
2, if confirm maximum frequency domain interval<BW
CA/ N then can be limited to synchronization and only on a up-link carrier, transmit PUCCH.
3, further, can also can also revise PUCCH frequency hopping mode in addition and allow between time slot not that frequency hopping can concentrate on the PUCCH of two member carriers the transmission of frequency band central authorities like this, specifically as shown in Figure 8.
4, further, limited if the user of system edges obtains the back-off value, can not satisfy the user performance gain, then can PUCCH and PUSCH be bound transmission, promptly adjust the distributing position of frequency domain resource according to the mode under first kind of situation.
Based on the foregoing description, to consult shown in Figure 9ly, in the embodiment of the invention, the terminal comprises confirms unit 90, acquiring unit 91 and adjustment unit 92, wherein,
Confirm unit 90, Network Environment is confirmed local maximum power rollback MPR threshold value;
Acquiring unit 91 is used for according to the MPR threshold value that obtains, and obtains the maximum frequency domain interval to should the MPR threshold value being provided with;
Adjustment unit 92, the distributing position of the discrete frequency domain resource that is used for according to the maximum frequency domain interval that obtains this locality being assigned to adjusts accordingly, and makes the frequency domain interval between each frequency domain resource be no more than above-mentioned maximum frequency domain interval.
In the embodiment of the invention; For the scene that adopts discontinuous frequency domain resource to carry out uplink in the LTE-A system; The MPR threshold value that the terminal can be confirmed according to Network Environment obtains corresponding maximum frequency domain interval, and the distributing position of discrete frequency domain resource of this terminal being used based on this maximum frequency domain interval is again adjusted; Like this; On adjusted discontinuous frequency domain resource, during transmission signals, effectively reduce the band external leakage that intermodulation product caused that produces between each frequency domain resource, thereby guaranteed the uplink signal transmissions quality; When making full use of the user performance gain that the transmission of discrete frequency domain brings, avoided the harmful effect that coexistence of systems and systematic function are caused.

14. like claim 8,9 or 10 described devices, it is characterized in that, when the distributing position of the said frequency domain resource that this locality is assigned to according to the maximum frequency domain interval that obtains adjusts accordingly,
If Physical Uplink Control Channel PUCCH is carried in a plurality of up-link carriers and transmits, judge that then whether maximum frequency domain interval is more than or equal to BW
CA/ N if the position that then will carry the frequency domain resource of PUCCH is adjusted to the upper sideband or the lower sideband of each up-link carrier, makes the frequency domain interval between the position of each frequency domain resource be no more than said maximum frequency domain interval; Otherwise, only on a up-link carrier, transmit PUCCH at synchronization, wherein, BW
CABe aggregate bandwidth, N is the up-link carrier number when pre-polymerization; Perhaps,
If Physical Uplink Control Channel PUCCH is carried in a plurality of up-link carriers and transmits, then the PUCCH that transmits on each up-link carrier is concentrated on frequency band central authorities and transmit.
