Description

A kind of method and apparatus for distributing ascending power
Technical field
The present invention relates to field of communication technology more particularly to a kind of technologies for distributing ascending power.
Background technology
In heterogeneous network, the introducing of low-power network node faces lot of challenges, such as uplink（UL, up link）/ under Row（DL, down link）Unbalanced power, mobile robustness（mobility robustness）, switching frequently, thus cause Signaling overload, and because of non-ideal backhaul（non-ideal backhaul）Resource utilization is low etc. between caused node, this Significantly limit network performance.
In 3GPP RAN2, dual link（dual-connectivity）It is defined as the effective solution to solve the above problems Scheme.In dual link, user equipment（UE）At least two network nodes are connected to simultaneously, identical or different frequency can be operated in Rate.Dual link typically can be applied to, by non-ideal backhaul, such as have pine delay and the backhaul of capacity requirement, be connected to each other Multiple base stations such as eNB（evolved-NodeB）.
Carrier wave polymerize（CA, Carrier aggregation）It can be used for realizing dual link, wherein a wireless connection can It is operated in portion of carriers component（CC, component carrier）On, and other wireless connections can be operated on other CC, As shown in Figure 1, wherein UE is connected to macrocell eNB simultaneously（macro-cell eNB）With cell eNB（small-cell eNB）, by non-ideal backhaul non-ideal backhaul connections between macro-cell eNB and small-cell eNB, Macro-cell eNB are that UE configures one group of carrier component such as CC1 and CC2, and small-cell eNB are that UE configures one group of carrier wave point Amount such as CC3 and CC4.
However, in 3GPP LTE-Advanced Release10/11, by multiple serving cells of CA polymerizations by identical ENB control, ascending control information（UCI, uplink control information）Notice has some rules, such as extremely More Physical Uplink Control Channel（PUCCH, Physical Uplink Control Channel）Or the shared letter of physical uplink Road（PUSCH, Physical Uplink Shared Channel）UCI, and the PUCCH of carrying UCI and carrying UCI can be transported PUSCH cannot be transmitted in same subframe.
To realize that the dual link with CA, multiple serving cells of aggregation need to be controlled by separate eNB, therefore, pass System CA technologies should be enhanced, and such as UCI should be in multiple carrier components（CC, component carrier）It is upper transmission rather than only Corresponding to main plot（PCC, primary cell）CC on transmit, this just need on different CC simultaneously parallel transmission it is multiple The PUCCH of UCI is carried, the PUCCH's and carrying UCI of the PUSCH and simultaneous transmission carrying UCI of the multiple carrying UCI of simultaneous transmission PUSCH.As a result, for different physical channels（Such as different PUCCHs and PUSCHs）Ascending power distribution mechanism should be by again Consider to support these new UCI for CA to be multiplexed rule.
In addition, because different eNB is grouped together in dual link network, from macro-cell eNB to desired UE Path loss and significantly different from the path loss small-cell eNB to desired UE, this is also influenced for not jljl Manage the ascending power distribution of channel.
And in current 3GPP LTE-Advanced Release10/11, according to the introduction of CA, multiple PUSCH can be not With parallel transmission on CC, and simultaneous transmission PUSCH and PUCCH are also possible on identical or different CC.
In principle, the power control of each physical channel is separate.The power control of each physical channel is obvious It ensure that total transmission power is without departing from every carrier wave maximum transmission power P for giving CCCMAX,C.However, independent power control Algorithm cannot be guaranteed to wait for defeated no more than UE maximums corresponding with UE power levels by the total transmission power of the UE all CC sent Go out power PTMAX.Certainly, this can be by carrying out power adjustment to physical channel（power scaling）To ensure.
The elementary tactics of UL power distributions is any UCI has higher priority than data transmission.Therefore, in LTE In Release10/11, the UL power allocation rules of the physical channel about carrying UCI are summarized as follows：
● if PUCCH exists, and according to its independent power control algorithm, gives PUCCH distribution powers first；
● if PUCCH is not present, and UCI is carried by PUSCH, according to the independent power control algorithms of PUSCH, gives carrying first The PUSCH distribution powers of UCI.
It should be noted that in the case of parallel transmission multiple PUSCH, at most a PUSCH may include UCI, can not be simultaneously The PUSCH of the PUCCH and carrying UCI of transmission carrying UCI will not have in this way, between the rule of the above Release10/11 Any conflict.
If remaining available transmission power is insufficient for the power demand of any residue PUSCH to be transmitted, these The remaining physical channel of only carrying data will carry out power adjustment so that the general power of all physical channels to be transmitted does not surpass Cross UE peak power outputs.Generally speaking, include the PUSCH power adjustments of the PUSCH for carrying UCI with priority, it can quilt It is expressed as：
Wherein, wc≤ 1, wcFor the power adjusting factor about PUSCH on carrier wave c（power scaling factor）, PPUCCHIndicate the power of the PUCCH of carrying UCI.For the PUSCH, regulation coefficient w of any carrying UCIcIt should be set as 1.For Remaining PUSCH, regulation coefficient wcIt is set to less than or the identical numerical value equal to 1 is to ensure to meet above-mentioned inequality.
However, in the doubly-linked welding system based on CA, because the PUCCH and simultaneous transmission of the multiple carrying UCI of simultaneous transmission are more The PUSCH of a carrying UCI, above-mentioned UL power distribution mechanisms and the power adjustment for being only used for the PUSCH of carrying data are inappropriate 's.
