Description

A kind of method and apparatus for distributing ascending power

Technical field

The present invention relates to communication technical field, particularly relating to a kind of technology for distributing ascending power.

Background technology

In heterogeneous network, the introducing of low-power network node faces lot of challenges, such as up (UL, up link)/descending (DL, down link) unbalanced power, mobile robustness (mobilityrobustness), switch the signaling overload that causes frequently, thus, and between the node to cause because of imperfect backhaul (non-ideal backhaul), resource utilization is low etc., this significantly limits network performance.

In 3GPP RAN2, dual link (dual-connectivity) is defined as the effective solution solved the problem.In dual link, subscriber equipment (UE) is connected at least two network nodes simultaneously, and it can be operated in identical or different frequency.Dual link typically can be applicable to by imperfect backhaul, and as having the backhaul of pine delay and capacity requirement, the multiple base stations be connected to each other are as eNB(evolved-NodeB).

Carrier aggregation (CA, Carrier aggregation) can be used to realize dual link, wherein, one wireless connections can be 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(macro-cell eNB simultaneously) and small-cell eNB(small-cell eNB), connected by imperfect backhaul non-idealbackhaul between macro-cell eNB and small-cell eNB, macro-cell eNB is that UE configures one group of carrier component as CC1 and CC2, small-cell eNB is that UE configures one group of carrier component as CC3 and CC4.

But, in 3GPP LTE-Advanced Release10/11, multiple Serving cells of being polymerized by CA are controlled by identical eNB, ascending control information (UCI, uplink controlinformation) notice have some rule, a such as Physical Uplink Control Channel (PUCCH at the most, Physical Uplink Control Channel) or Physical Uplink Shared Channel (PUSCH, Physical Uplink Shared Channel) can UCI be transported, and the PUCCH of carrying UCI can not transmit with the PUSCH of carrying UCI in identical subframe.

For realizing the dual link with CA, multiple Serving cells of assembling need be controlled by respective independently eNB, therefore, traditional C A technology should be enhanced, such as UCI should at multiple carrier component (CC, component carrier) above transmit instead of only corresponding to main plot (PCC, primary cell) CC on transmission, this just needs the PUCCH of the UCI of the multiple carrying of parallel transmission simultaneously on different CC, transmit the PUSCH of multiple carrying UCI simultaneously, and the simultaneously PUCCH of transmission bearer UCI and the PUSCH of carrying UCI.As a result, the ascending power distribution mechanism for different physical channel (PUCCHs and PUSCHs as different) should be reconsidered to support the multiplexing rule of these new UCI for CA.

In addition, because different eNB is grouped together in dual link network, from the path loss macro-cell eNB to the UE expected from obviously different from the path loss small-cell eNB to the UE expected, this ascending power also affected for different physical channel distributes.

And in current 3GPP LTE-Advanced Release10/11, according to the introduction of CA, multiple PUSCH can on different CC parallel transmission, and on identical or different CC, transmit PUSCH and PUCCH be also possible simultaneously.

In principle, the power of each physical channel controls to be separately independently.The power of each physical channel controls obviously to ensure that for given CC, and total transmitting power can not exceed every carrier wave maximum transmission power P _{cMAX, C}.But independent power control algorithm can not ensure to treat that total transmitting power of all CC sent by UE is no more than the UE peak power output P corresponding with UE power level _tMAX.Certainly, this ensures by carrying out power adjustment (power scaling) to physical channel.

The elementary tactics of UL power division is that any UCI has higher priority than transfer of data.Therefore, in LTE Release10/11, the UL power allocation rules about the physical channel of carrying UCI is summarized as follows:

● if PUCCH exists, and according to its independently power control algorithm, first distributes power to PUCCH;

● if PUCCH does not exist, and carries UCI by PUSCH, according to PUSCH independently power control algorithm, distributes power first to the PUSCH of carrying UCI.

It should be noted that a PUSCH can comprise UCI at the most when the multiple PUSCH of parallel transmission, can not the simultaneously PUCCH of transmission bearer UCI and the PUSCH of carrying UCI, like this, between the rule of above Release10/11, will not any conflict be had.

The power demand that available transmitting power is not enough to meet any residue PUSCH to be transmitted if remain, these residue physical channels only carrying data will carry out power adjustment, make the gross power of all physical channels to be transmitted be no more than UE peak power output.Generally speaking, comprise the PUSCH power adjustment of the PUSCH of the carrying UCI with priority, can be represented as:

$\underset{c}{\mathrm{\Σ}}{w}_c\·P_{\mathrm{PUSCH},c}\≤P_{\mathrm{TMAX}}-P_{\mathrm{PUCCH}}$

Wherein, w _c≤ 1, w _cfor about the power adjusting factor of PUSCH on carrier wave c (powerscaling factor), P _pUCCHrepresent the power of the PUCCH of carrying UCI.For the PUSCH of any carrying UCI, regulation coefficient w _cshould 1 be set to.For residue PUSCH, regulation coefficient w _cthe identical numerical value be set to less than or equal 1 is to ensure to meet above-mentioned inequality.

But, based in the dual link system of CA, because transmitting the PUCCH of multiple carrying UCI and transmit the PUSCH of multiple carrying UCI simultaneously simultaneously, above-mentioned UL power distribution mechanism and be only unsuitable for carrying the power adjustment of the PUSCH of data.
