Specific embodiment is lifted below to be discussed in detail.
Embodiment one:
Based on the terminal with different peak power outputs: LTE standard power cluster may be present in TD-LTE group system
Terminal and high-power cluster terminal.For LTE standard power colony terminal, LTE standard is continued to use to Uplink Shared Channel power control
The transimission power P of the regulation of system, i.e. LTE standard power the colony terminal PUSCH in subframe iPUSCHIs defined as:
PPUSCH(i)=min { PCMAX,10log10(MPUSCH(i))+PO_PUSCH(j)+α(j)·PL+ΔTF(i)+f(i)}
[dBm]
(1)
For high-power cluster terminal, the present invention takes into account the link efficiency for improving high-power cluster terminal and reduces big function
Rate terminal considers the interference these two aspects of minizone, proposes the rule to the Uplink Shared Channel power control of high-power terminal
It is fixed, i.e. the transimission power P of high-power cluster terminal PUSCH in subframe iPUSCHIs defined as:
Wherein, PCMAXIt is to allow its configuration maximum transmission power of high-power cluster terminal profile.
PRB_MAXIt is maximum allowable transmission power of the high-power cluster terminal in resource block (RB).Other in formula (2) are joined
The same LTE protocol of several regulations does not make tired state herein.
P in formula (2) is described belowCMAXAnd PRB_MAXAcquisition modes.
Firstly, PCMAXNumerical value in such as Lower Limits:
PCMAX_L≤PCMAX≤PCMAX_H (3)
Wherein,
PCMAX_L=min { PEMAX_HighPowerUE–TC,PPowerClass–MPR–A-MPR–TC}；
PCMAX_H=min { PEMAX_HighPowerUE,PPowerClass}；
PEMAX_HighPowerUEIt is the maximum allowable transmission power that base station is sent to high-power terminal, it is high-power for limiting
The uplink transmission power of terminal.For PEMAX_HighPowerUEIt is the numerical value of which cell, there is following two implementation.
Implementation one: indicate that base station is sent to big function using original P-MAX cell in 36.331 agreement of 3GPP TS
The maximum allowable transmission power of rate terminal, i.e. PEMAX_HighPowerUEIt is the numerical value for the cell P-Max that base station sends RRC information.
Implementation two: newly-increased cell indicates that base station is sent to the maximum allowable transmission power of high-power terminal, i.e.,
PEMAX_HighPowerUEIt is the numerical value that base station sends the newly-increased cell P-Max-forHighPowerUE of RRC information.Specifically, P-
Max-forHighPowerUE can increase this parameter newly in SIB1 cell, can also be in newly-increased cluster information block
Increase this parameter in SIBTrunking newly.The parameter is optional cell-level parameter, if the parameter does not indicate, high-power end
End determines maximum transmission power according to the power grade of terminal.
For two kinds of above-mentioned implementations, the maximum of high-power terminal can be determined according to the system requirements of group system
Which kind of implementation output power determines using.Since the value range of regulation P-Max in agreement is [- 30,33], if collection
The maximum of group's system designing high-power terminal sends power within this range, optional implementation one.If group system designs
The maximum transmission power of high-power terminal is super to go beyond the scope, optional implementation two.
PPowerClassIt is the peak power output of high-power cluster terminal, does not consider the various tolerances of definition, value can
To be 38dBm, it is also possible to other values.
Provide that the power of TD-LTE terminal (UE) there are 4 grades in LTE protocol.Currently define only power grade 3
It is required that, it is desirable that for all TDD frequency ranges, the peak power output in channel width under any transmitted bandwidth is 23dBm,
Tolerance is ± 2dB.Due to the introducing of high-power cluster terminal, the present invention defines power etc. to based on TD-LTE group system
The requirement of grade 4 is required for all TDD frequency ranges, the peak power output in channel width under any transmitted bandwidth is
38dBm, tolerance are ± 2dB, and the peak power output that can also need to define high-power cluster terminal according to system is other
Value.That is, high-power cluster terminal is set to the terminal of power grade 4, mentioned-above LTE standard power colony terminal
For the terminal of power grade 3.
PRB_MAXIt is maximum allowable transmission power of the high-power cluster terminal in resource block (RB), base station passes through newly-increased
Parameter P-RB-Max-forHighPowerUE is increased in SIBTrunking newly P is arrangedRB_MAXNumerical value.The parameter can limit
High-power cluster terminal reasonably configures the parameter in the maximum transmission power of each RB, can further decrease high-power end
End especially reduces the interference to LTE standard power colony terminal in adjacent area to the interference co-frequency cell.
To realize that eNB sends above-mentioned parameter to high-power cluster terminal, new system message type: Syst can be increased
emInformationBlockTypeTrunking.UE application SystemInformationBlockTypeTrunking is obtained
Process obtains the relevant system information of cluster.Correspondingly, in SystemInformation and
Increase new Sib type (Sib Type), i.e. SystemInformationB in SystemInformationBlockType1
LockTypeTrunking, and increase a kind of cluster information of SystemInformationBlockTypeTrunking type newly
Block, i.e. SIBTrunking.
Three embodiment introductions increase eNB newly in newly-increased SIBTrunking and are sent to high-power cluster terminal below
Maximum allowable transmission power P-Max-forHighPowerUE cell and high-power cluster terminal permit in the maximum of resource block (RB)
Perhaps three kinds of modes of transmission power P-RB-Max-forHighPowerUE cell.
In addition, eNB needs to know the power grade of terminal.Because of the peak power output of LTE standard power colony terminal
Only 23dBm grade is to be not required to be reported to the power grade that eNB knows UE；But due to the introducing of high-power cluster terminal, mesh
Before there are terminal peak power outputs there are 2 kinds of power grades, eNB is the power grade for needing to know terminal.In view of to the greatest extent
It is likely to reduced the problem of space interface signaling expense and terminal compatibility, LTE standard power colony terminal is not required to report power etc.
Grade, and high-power cluster terminal increases reporting for power grade.Specifically, can believe in UECapabilityInformation
Increase the power grade that ue-PowerClass parameter carrys out instruction terminal in member newly.The ue-PowerClass is optional parameters, instruction
4 grades of terminal power.In addition, terminal can also direct reporting terminal type, only one indicating bit of needs can be real in this way
Now report.
For UE, then need to increase ue-PowerClass parameter for its power etc. if it is high-power cluster terminal
Grade is reported to group system, can not then report power grade if it is LTE standard power colony terminal.
For eNB, if terminal does not report power grade, then it is assumed that be the terminal that power grade is 3, i.e., most
Big output power is 23dBm；If terminal has reported power grade, known according to specific value in ue-PowerClass
The peak power output of terminal.
