It should be noted that in the LTE system,, concerning a UE, can not send PUSCH and PUCCH simultaneously for keeping the single-carrier property of upward signal.
For making the allowance between transmitting power estimated of maximum configured power output that the base station can know that at a time certain UE is provided with and its physical uplink channel of dispatching, thereby for carrying out scheduling of resource and link circuit self-adapting provides foundation in the base station, UE need calculate the margin of power PH (Power Headroom claims the power rising space again) of self and report to the base station.In the LTE system, the margin of power of certain UE on subframe i is defined as:

In addition, (Power Headroom Report is PHR) by Event triggered (event-triggered) in the report of margin of power.When UE has new upstream data to transmit in current subframe, and the report of Event triggered margin of power is arranged, and when the channel resource that the base station is distributed for the PUSCH of this UE transmission was enough to load power allowance MAC layer control unit (PowerHeadroom MAC Control Element) and mac-layer protocol data cell son head (MAC PDUsubheader) thereof in proper order according to certain priority of logical channels, UE reported to the base station by margin of power MAC layer control unit with the margin of power index of 6bits.
The structure of margin of power MAC layer control unit as shown in Figure 1, it is 1 eight bit byte (octet), wherein the highest 2 can be changed to ' 0 ' usually for reservation bit (representing with R), low 6 margin of powers (representing with the PH index) for report.
Margin of power MAC layer control unit by contain the 5bits Logic Channel Identifier (LogicalChannel ID, LCID) mac-layer protocol data cell head identifies, its LCID is " 11010 ".
It should be noted that in the LTE system, only to sending the subframe rated output allowance of PUSCH.
LTE-Advanced system (evolution LTE system also can abbreviate the LTE-A system as) is the evolution system of future generation of LTE system.As shown in Figure 2, the LTE-A system adopts carrier aggregation (carrieraggregation) technological expansion transmission bandwidth, and the carrier wave of each polymerization is called one " component carrier " (component carrier).A plurality of component carriers can be continuous (as being spaced apart 0 between component carrier #1 among Fig. 2 and component carrier #2), it also can be discontinuous (as existing at interval between component carrier #2 among Fig. 2 and component carrier #3), same frequency range (operating band) can be positioned at, also different frequency range can be positioned at.
In the LTE-A system, subscriber equipment can send a PUSCH on (up) component carrier, also can send a plurality of PUSCH respectively simultaneously on a plurality of (up) component carrier.In addition, can also on (up) component carrier, send a plurality of Physical Uplink Control Channel PUCCH, and on (up) component carrier, send PUSCH and PUCCH simultaneously.
Complexity and diversity in view of carrier aggregation scene and user equipment transmitter structure, in the prior art, defined the threshold value of two kinds of transmitting powers, be respectively the emission maximum gross power (a UE-specific maxpower, a max power for the total UE transmit power) of the maximum transmission power (aCC-specific max power) and the subscriber equipment of component carrier.The transmitting power of subscriber equipment on each component carrier must not surpass the maximum transmission power of its component carrier, and the total emission power of subscriber equipment must not surpass the emission maximum gross power of this subscriber equipment.In case surpassed wherein any one threshold value, all must reduce the transmitting power of respective physical up channel.
And then, in the prior art, the calculating and the report that have proposed respectively based on the margin of power of component carrier (are that subscriber equipment calculates the margin of power on each component carrier respectively, and then report to the base station respectively, be called the component carrier margin of power), and based on the calculating of the total power margin of subscriber equipment and report (be the emission maximum gross power of subscriber devices compute subscriber equipment and each related physical up channel estimate the poor of transmitting power sum, report to the base station again, be called the subscriber equipment total power margin).
Therefore, subscriber equipment two class margin of powers more than the report of base station how in having adopted the LTE-A system of carrier aggregation, for carrying out scheduling of resource and link circuit self-adapting provides enough margin of power information in the base station, and make the base station can know the kind of the margin of power of district office's report, the saving signaling expense has become a problem demanding prompt solution simultaneously.
