Description
Technical field
The present invention relates to the communications field, in particular to a kind of the definite of transmit power, signaling configuration method and dress
Put, terminal, base station.
Background technology
In Long Term Evolution (Long Term Evolution, abbreviation LTE), Physical Downlink Control Channel (Physical
Downlink Control Channel, abbreviation PDCCH) believe for carrying uplink and downlink scheduling information and uplink power control
Breath.Downlink Control Information (Downlink Control Information, abbreviation DCI) form (format) is divided into DCI
Format 0,1,1A, 1B, 1C, 1D, 2,2A, 3,3A etc., behind evolution into LTE-A versions 12 (LTE-A Release 12)
DCI format 2B, 2C, 2D are added again to support a variety of different applications and transmission mode.First communication node (e-
Node-B, referred to as eNB) can the second communication node (User Equipment, abbreviation UE) be configured by Downlink Control Information,
Or second communication node receive the configuration of high-rise (higher layers), UE is also referred to as configured by high-level signaling.
Uplink power control in wireless system is very important, and by uplink power control, can cause the UE in cell
Not only ensure the quality of data transmitted by uplink, but also reduced the interference to other users in system as far as possible, and extend making for UE batteries
Use the time.
It is orthogonal with the upstream data between different user in cell, therefore, LTE system is adopted in LTE/LTE-A systems
It is main to consider to adapt to different wireless transmission rings by Power Control come uplink with uplink power control at a slow speed
Border, including path loss, shadow fading etc..The object of LTE Power Controls includes PUCCH, PUSCH, SRS etc..Although these uplinks are believed
Number data rate and importance it is each different, specific circule power control method and parameter are also not quite similar.But its principle is all basic
Identical, it can be summarized as：
Power spectral density (power i.e. per resource block on (resource block, referred to as RB))=open loop of UE transmittings
Industry control point+dynamic power excursion.Wherein, path loss compensation α × (PL) of open loop industry control point=target power P0+ open loops.Target
Power P 0 is divided into as cell target power and the specific target power two parts of UE.
The path loss PL of open loop is estimated based on UE for the path loss of downlink.UE is by measuring downlink reference signal RSRP with reference to letter
Number reception power (Reference Signal Received Power, abbreviation RSRP), and with known RS signal powers into
Row subtracts each other, so as to carry out path loss estimation.
For PUSCH and SRS, eNodeB determines ascending power control of the path loss in UE by parameter road loss compensation factor α
Weight in system.Such as being in the UE of cell edge, if its transmit power is excessively high, other cell can be caused to do
It disturbs, so as to reduce the capacity of whole system.For PUCCH, since different PUCCH users is code division multiplexing, α values
For 1, the interference between different PUCCH users can be preferably controlled.
Dynamic power excursion includes two parts, based on modulation coding scheme (Modulation Coding Scheme,
Abbreviation MCS) power adjustment △ TF and closed loop Power Control.Power adjustment based on MCS can cause UE according to selected
MCS dynamically adjusts corresponding transmission power spectrum density.The Power Control of closed loop refers to that UE passes through the transimission power in PDCCH
Control (Transmitting Power Command, abbreviation TPC) transimission power order is adjusted come the transmission power to UE.
Accumulation adjustment can be divided into and absolute value adjusts two ways.It accumulates adjustment mode and is suitable for PUSCH, PUCCH and SRS, definitely
Value adjustment mode is only applicable to PUSCH.Conversion between both different adjustment modes is semi-static, and eNB passes through special
RRC wireless heterogeneous networks (Radio Resource Control, abbreviation RRC) signaling instruction UE is using accumulation mode or absolute
Value mode.
Accumulation mode refers to that current power adjusted value is in one TPC of numerically increase/reduction of last time power adjustment
The adjusting step of instruction, accumulation mode are the default adjustment modes used of UE.The TPC for accumulating mode in LTE can have two sets not
Same adjusting step, first set step-length are (- 1,0,1,3) dB, for PUSCH, are indicated by DCI format 0/3；For
PUCCH is indicated by DCI format 1/1A/1B/1D/2/2A/3.Second set of step-length is (- 1,1), is referred to by DCI format 3a
Show and (be suitable for PUCCH and PUSCH).
Absolute-value sense refers to, directly using the power adjustment numerical value indicated in TPC, be only applicable to PUSCH.At this point,
ENodeB needs accumulation mode is explicitly closed by RRC signaling power adjustment mode.When using absolute-value sense, TPC
Numerical value be (- 4, -1, Isosorbide-5-Nitrae) dB, indicated by DCI format 0/3, power adjustment scope up to 8db, do not connect suitable for UE
Continuous uplink can cause the transmission power of mono- successive step UE of eNodeB to desired value.
With the development of the communication technology, data traffic requirement amount is continuously increased, and available low frequency carrier signal is also very dilute
It lacks, is become based on high frequency (30~300GHz) carrier communication also underused solve following high-speed data communication as a result,
One of important communication means.The available bandwidth of high frequency carrier communication is very big, can provide effective high-speed data communication.But
A very big technological challenge facing of high frequency carrier communication is exactly：Rather low-frequency signals, decline of the high-frequency signal in space are non-
Chang great, although high-frequency signal can be caused the fading loss problem in space occur in outdoor communication, due to its wavelength
Reduce, can usually use more antennas, so as to communicate to compensate the fading loss in space based on wave beam.
But when antenna number increases, since each antenna being needed to have a set of radio frequency link at this time, based on digital beam
Shaping is also brought the problem of increasing cost and power attenuation.Therefore, compare in the research in correlation technique and tend to mixed recharge
Final wave beam is collectively formed in beam figuration, i.e. radio frequency beam and digital beam.
In the research of new wireless access technology (New Radio Access Technology, abbreviation NRAT), high frequency
Except the first communication node can configure, substantial amounts of antenna forms downlink transmission beam to compensate the space of high-frequency communication to communication system
Decline, the second communication node equally can also configure substantial amounts of antenna and form uplink wave beam, and the first communication node side can also be selected
Suitable reception wave beam is selected to match reception uplink signal.In the research of correlation technique, it has been determined that proprietary using wave beam
Uplink power control mechanism, but how to realize and flexibly and effectively configure, it is current uplink power control to adapt to the plurality of application scenes of NRAT
Problem to be solved in standardization.
For the above-mentioned technical problem in correlation technique, currently no effective solution has been proposed.
