Description

Poewr control method and device
Technical field
The present invention relates to the communications field, in particular to a kind of Poewr control method and device.
Background technology
Since 3GPP R10 versions, to meet IMT-Advanced (International Mobile Telecommunications - Advanced, IMT-Advanced) demand, LTE-A (Long Term Evolution-Advanced, LTE evolution) In employ CA (Carriers Aggregation, carrier aggregation) technology further support than LTE ((Long Term Evolu - tion, Long Term Evolution) broader communication bandwidth.The cardinal principle of carrier aggregation is multiple to LTE backward compatibility by polymerizeing Carrier wave, can support maximum 100MHz bandwidth.In the system of carrier aggregation is introduced, the carrier wave being polymerize referred to as CC (Component Carrier, component carrier), also referred to as one Cell (cell).It is also proposed that PCC/PCell (Pr - imary Component Carrier/Cell, principal component carrier wave/cell) and SCC/SCell (Secondary Component Car - rier/Cell, auxiliary component carrier/cell) concept.In the system for carrying out carrier aggregation, including at least a PCC/PCell And SCC/SCell, wherein PCC/PCell are constantly in state of activation.When the upward signal on multiple CC is sent simultaneously, if The total transmission power of upward signal on multiple CC can be supported most more than PA (Power Amplifier, power amplifier) Big linear power, then carry out power extraction, to ensure the transmission power of all upward signals and not surpass to all upward signals Cross the maximum linear power that PA can be supported.
For example, transmitting PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) and transmitting simultaneously is not Comprising UCI (Uplink Control Information, ascending control information) PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) when, power extraction (Power Scaling) formula is:
For example, during the PUSCH of PUSCH and transmitting of the transmitting simultaneously not comprising UCI comprising UCI, power extraction formula is:
For example, during PUSCH of the PUSCH of transmitting PUCCH and transmitting not comprising UCI and the transmitting simultaneously comprising UCI, work( Rate cuts down formula:

The Power Control carried out simultaneously on some CC is PSD (Power Spectral Density, power spectral density) and opened The mode that ring, closed loop are combined, wherein PSD represent the calculating carried out with RB (Resource Block, resource block) for unit, Assume power required when all RE (Resource Element, resource unit) are all occupied in unit RB.Then in tool During body transmitting business, power used can be calculated according to allocated RB quantity.More specifically, final calculating power includes Allocated RB quantity, PSD, path loss supplement, the modulating-coding form of transmitting data, accumulative or absolute power adjustment amount.
For example, PUSCH power is:
For example, PUCCH power is:
Above-mentioned two formula can be abbreviated as:
Pc(i)=min { PCMAX,c(i), 10log10(Mc(i))+PO, c(j)+PLc+TFc(i)+fc}, (i) wherein Pc(i) represent to carry Ripple indexes the calculating power of upper i-th of the subframe of c, PCMAX,c(i) the maximum allowable transmitting work(of upper i-th of the subframe of carrier index c is represented Rate, Mc(i) scheduling RB quantity, the P of upper i-th of the subframe of carrier index c are representedO, c(j) j={ 0,1,2 } represents semi-static respectively Corresponding PSD, PL when scheduling business, dynamic dispatching business, Stochastic accessingcRepresent the path loss supplement on carrier index c, TFc(i tables Show the modulating-coding form of the transmitting data of upper i-th of the subframe of carrier index c, fc(i) the accumulative of upper i-th of the subframe of carrier index c is represented Or absolute power adjustment amount.In addition, industry is PO,c(j)+PLcRegard open Loop Power control as, TFc(i)+fc(i) regard as Close-loop power control, PO,c(j) PSD (this is defined for the first PSD) is regarded as, or PO, c(j)+TFc(i)+fc(i) see Work is PSD (this is second of PSD definition).
Above-mentioned CA is to be directed to authorize carrier wave, and with the rapid growth of data service, the data born on the carrier wave for authorizing frequency spectrum Transmit pressure also increasing, therefore, shared by the carrier wave of unlicensed spectrum and authorize the data traffic in carrier wave to turn into follow-up One important evolution tendency of LTE development.
The Rel-13 versions of LTE system start registration study in September, 2014 part, and the important research theme of one of which is exactly LTE system uses the carrier operation of unlicensed spectrum, also referred to as LAA (Licensed Assisted Access authorize auxiliary access). The carrier wave for the unlicensed spectrum for LTE system being used presently, there are is greatly promoted the potential of LTE system by this technology Frequency spectrum resource so that LTE system results in lower frequency spectrum cost.
The characteristics of unauthorized carrier wave has following:
1st, free/low expense:Unlicensed spectrum need not be bought, frequency spectrum resource is zero cost;
2nd, requirements for sale is low, cost is low:Personal, enterprise can participate in deployment, and the equipment of equipment vendor can be disposed arbitrarily;
3rd, available bandwidth is big:The frequency ranges such as 5GHz, 2.4GHz in unlicensed spectrum can be used, big with available bandwidth Feature;
4th, shared resource:When multiple different systems are all runed wherein, or same system different operators operation wherein when, can In the way of considering some shared resources, spectrum efficiency is improved;
5th, wireless access technology is more:Different communication standards can be used, but cooperation difficulty is big, and network topology is various;
6th, wireless access website is more:Number of users is big, but cooperation difficulty is big, and centralized management expense is big;
7th, using many:Multiple business can be runed wherein, for example:M2M (Machine to machine, machine to machine) Business, V2V (Vehicle to vehicle, automobile to automobile) business.
These characteristics determine that unauthorized carrier wave is probably one important evolution tendency of wireless communication system, but if to apply Unauthorized carrier wave needs to meet the control requirement issued in industry or region, wherein the control for shared bandwidth is, transmitting terminal hair 80% bandwidth resources for taking system bandwidth or nominal bandwidth are met when penetrating.
At present, industry will all take the 80% bandwidth money of system bandwidth or nominal bandwidth when how research meets transmitting terminal transmitting Source.For example, data distribution to be launched in 80% bandwidth resources, or interweave onto 80% bandwidth resources, or be mapped to In 80% bandwidth resources.Specifically include and continuous or Discrete Mapping is carried out by subcarrier, in units of resource block.Specifically, it can be divided into It is following several:
1st, Single UE (User Equipment, user equipment) actually take 80% bandwidth resources, including:
(1-1) 80% bandwidth resources are using RB centralizations;
(1-2) 80% bandwidth resources are distributed using RB;
(1-3) 80% bandwidth resources are using RE centralizations;
(1-4) 80% bandwidth resources are distributed using RE.
2nd, the bandwidth resources of Single UE spans 80%, but do not indicate that and actually take, including:
(2-1) pectinate texture is dispersed in span more than or equal in the range of 80% bandwidth resources;
(2-2) clustering architecture is dispersed in span more than or equal in the range of 80% bandwidth resources.
3rd, Single UE use the power of " actually taking 80% bandwidth resources " to concentrate and take a small amount of bandwidth, including:
Power corresponding to (3-1) a small amount of bandwidth needs to meet CCA (Clear Channel Assessment, clear channel assessment (CCA)) Detection threshold requirement.
4th, Multiple UE are actual takes 80% bandwidth resources, including:
(4-1) eNB (evolved base station) scheduling multiple UE are automatically considered and have been met control, but regardless of UE whether CCA Success;
(4-2) multiple UE launch Seize ACK message using common muting UE.
However, after above-mentioned processing, it is existing to be applied to authorize the Power Control of carrier wave, distribution or the mechanism of adjustment Can not directly it apply again.Now, if still with for authorizing being carried out based on the PSD that all RE are taken in unit RB for carrier wave Power Control will cause power dissipation.After the CCA failures of unauthorized carrier wave, the remaining CC shared by transmitting terminal equally faces power The problem of cutting down processing, the problem can not equally be realized using the existing power extraction mechanism for authorizing carrier wave.In addition, by In the CCA of unauthorized carrier wave success is likely in subframe in optional position, and the adjustment of original system power is to be directed to whole subframe, Therefore the problem of part sub-frame power is adjusted etc. occurs.
