Description
Technical field
The present invention relates to determination method, processing chip and the communications of field of communication technology more particularly to a kind of transmission power
Equipment.
Background technology
It will be used relative to long term evolution (Long Term Evolution, LTE) higher carrier wave in 5G communication systems
Frequency (abbreviation high frequency), it is high frequency to be generally 6GHz or more according to current standard regulation, and the frequency range of current primary study has
28GHz, 38GHz, 72GHz etc., to realize the wireless communication of bigger bandwidth, higher transfer rate.However, relatively traditional low frequency
Communication, the middle radio frequency distortion of radio frequency system can be more serious, especially the influence of phase noise.In addition, Doppler and carrier frequency
The influence that rate offset (Carrier Frequency Offset, CFO) is brought can also increase as frequency is got higher.
With multi-I/O OFDM (Massive input massive output-Orthogonal
Frequency Division Multiplexing, MIMO-OFDM) for, while considering receiving terminal and transmitting terminal phase noise
And the case where carrier frequency shift, n-th after receiving terminal Fast Fourier Transform (FFT) (Fast Fourier Transform, FFT)
Reception expression formula on k-th of subcarrier of a reception antenna is：
Wherein,
I.e.：
Wherein,Indicate channel of m-th of transmission antenna to n-th of reception antenna on k-th of subcarrier,It indicates
The transmission data of m-th of antenna on k-th of subcarrier,Indicate making an uproar on k-th of subcarrier on n-th of reception antenna
Sound.Indicate receiving terminal phase noise and the CFO phase deviation caused by k-th of subcarrier on n-th of reception antenna,
Indicate transmitting terminal phase noise and the CFO phase deviation caused by k-th of subcarrier on m-th of reception antenna.It can from expression formula
To find out, influence of the phase noise to OFDM performances is mainly reflected in common phase error (Common Phase Error, CPE)
With two aspects of inter-carrier interference (Inter-carrier Interference, ICI)；Influences of the CFO to OFDM performances is main
It embodies on ICI.Wherein ICI is small compared with CPE to the influence of performance in systems in practice, therefore usually excellent in phase noise compensation scheme
First consider to compensate CPE.
Figure 1A is 64QAM modulated signals not by the constellation point of effect of phase noise；Figure 1B is 2G frequency range 64QAM modulated signals
By the constellation point of effect of phase noise；Fig. 1 C are constellation point of the 28G frequency range 64QAM modulated signals after by effect of phase noise.Such as
Shown in Figure 1A~Fig. 1 C, by taking phase noise as an example, with the increase of frequency range, phase noise level is with 20*log(f1/f2)Level
Deteriorate.By taking 2G frequency ranges and 28G frequency ranges as an example, the high 23dB of phase noise level ratio 2G frequency ranges of 28G frequency ranges.Phase noise level is got over
Height, common phase error (Common Phase Error, CPE) influence is bigger, and phase error is bigger caused by CPE.
The different sub-carrier of same OFDM symbol is influenced identical by CPE, due to being influenced by white Gaussian noise, is caused not
It is different with the phase error on subcarrier, therefore.On frequency domain, need through a certain number of phase compensation reference signals
(Phase compensation Reference Signal, PCRS) (is referred to as Phase Tracking reference signal (Phase
Tracking Reference Signal, PTRS)), industry does not have unified name, the present invention for convenience, follow-up to unite at present
One is known as PTRS) estimate CPE and is averaging, to reduce the influence of white Gaussian noise to the greatest extent.
Currently, for how to determine that the transmission power of PTRS is a technical problem urgently to be resolved hurrily.

Embodiment one：
Fig. 3 is resource grid (resource grid) figure of LTE system.As shown, in LTE system channel transmission
As unit of radio frames, a radio frames (radio frame) includes 10 subframes (subframe), the length of each subframe
For 1 millisecond (ms), each subframe includes two time slots (slot), and each slot is 0.5ms.The symbol that each slot includes
Number is related with CP (cyclic prefix, cyclic prefix) length in subframe.If CP is normal (common) CP, each
Slot includes 7 symbols, and each subframe is made of 14 symbols, if CP is extended (length) CP, each slot includes 6
Symbol, each subframe are made of 12 symbols.Downlink symbol is known as orthogonal frequency division multiple access (orthogonal frequency
Division multiplexing, OFDM) symbol.In LTE system, resource unit (resource element, RE) is time-frequency
Minimum unit on domain, by indexing to (k, l) unique mark, wherein k is sub-carrier indices, and l is notation index.
Relatively existing cordless communication network, the next generation wireless communication network for being operated in 6GHz range above will suffer from more
Add serious middle radio frequency distortion, the influence that especially phase noise is brought, phase noise level is higher, and CPE influences bigger.Therefore
PTRS is introduced for phase noise to estimate.
But PTRS can occupy some RE, and occupied RE is to be used for transmission data channel (wherein uplink originally
When, data channel includes Physical Uplink Shared Channel (physical uplink shared channel, PUSCH), and downlink passes
When defeated, data channel includes Physical Downlink Shared Channel (physical downlink shared channel, PDSCH)) or
Other reference signals of person.Wherein most commonly seen situation is that occupied RE is originally used for transmission data channel, for this
The general power of situation, PTRS should be equal to general power (the application implementation of the data channel to be sent originally on occupied RE
" power " described in example is equal to " transmission power ").Because the available general power of transmitting terminal is all pre-configured, if
The transmission power of PTRS is more than on occupied RE the transmission power for the data channel to be sent originally, and it will cause beyond available
General power the case where, and if the transmission power of PTRS is less than the transmission of the upper script data channels to be sent of occupied RE
The case where power, it will cause power dissipations, certainly, if the transmission power of PTRS is only slightly less than, (difference is no more than default
Threshold value) transmission power for the data channel to be sent and feasible originally on occupied RE.
It is transmitted as example with uplink, the script data channel to be sent on occupied RE is equal to by the transmission power of PTRS
Transmission power, it can be deduced that formula (1)：
Nlayers×NRE/layers×PPUSCH=NPTRS ports×NRE/PTRS ports×PPTRS (1)
Wherein, NlayersTo transmit the number of plies, NRE/layersFor can not be used due to PTRS in each transport layer RE numbers (with
1 resource block (resource block, RB), 1ODFM symbols are unit), PPUSCHFor PUSCH in the transport layer power (with 1
RE is unit), NPTRS portsFor the ports PTRS (port) number, NRE/PTRS portsFor the occupied RE numbers in each port PTRS (with
1RB, 1ODFM symbol are unit, it is assumed herein that for 1), PPTRSFor the power of PTRS (as unit of 1 RE).
Formula (2) can be from which further followed that by formula (1)：
And due to：NRE/layers=NPTRS ports×NRE/PTRS ports
It can from which further follow that formula (3)：
Formula (4) can be from which further followed that by formula (3)：
Relative power ratio=10log of PTRS and PUSCH10(Nlayers) (4)
