Definitions
- the measurement of the aggregation phase C bc ec, C of the component carrier Compo e Ca e C is mainly caused by the following factors: the downstream Dow k D reference Re e ce Sg a R and The number of aggregates C.
- An aspect of the present invention provides a method for multi-component carrier aggregation in an aggregate method, the method comprising: stepping each phase of the multi-component C with a phase characteristic in a phase set to apply a plurality of fixed phase characteristics to obtain each medium C
- the multi-phase version of any of the multi-phase special versions of each C is a plurality of amplitudes of the phase-specific version in each medium and a multi-phase special version having a minimum amplitude sum and a minimum amplitude sum.
- Each of the steps of the multi-component carrier C includes an inverse fast Fourier exchange for each of the multiple Cs.
- Another aspect of the present invention provides a multi-component carrier C for aggregation, each of which includes a hot-spot, a phase characteristic of each of the multi-component carriers C, and a plurality of fixed phases respectively applied by phase characteristics in the phase-specific set
- the sum of the multi-phase special versions of each C is more
- the magnitude of the phase-specific version in each medium is the same as the multi-phase version with the smallest amplitude sum and the minimum amplitude sum.
- One step involves fast Fourier's per-transverse fast Fourier exchange.
- step S1 multiple components of each of the CCs.
- step S103 a multi-fixed phase is applied by using the phase characteristics in the phase special set to obtain a multi-phase special version of each C.
- step 104 one of the multi-phase special versions of each C in the step is
- step 105 there is a minimum amplitude sum of the multi-dimensional version of the minimum amplitude sum in step S106.
- the most method is in step 5107.
- each 20 includes 201 phase of each of the multi-component carriers C.
- 202 uses the phase in the phase special set.
- each phase C multi-phase special version summation 203 any one of the multi-phase special versions of each C, respectively, the amplitude of the phase special version in each medium and 204 A multi-phase special version with a minimum amplitude sum and 205 with a minimum amplitude sum. among them
- 201 may include a fast Fourier exchange for each of the inverse C fast Fourier exchanges.
- 3 is the method of the multi-C and her method of Hugh, which is different from the method of D and D.
- each phase applied by C is specially combined with one of the combinations of Ps of each medium. . . o Go out one of the phases.
- the component of the component carrier with the smallest C APR that is, the component of the most C APR can be used in combination. As shown in Fig. 3, each phase is applied with a phase of 3 /2.
- the method is not in D, the phase is specific to C and is also used in L
- the method shown in 3 is a combination of only the minimum C / PAPR of the phase in each C.
- One method can't increase the C caused by RS periodicity and the inherent C / PAPR, and the DL drops by 2dB.
- the existing wood scheme can only increase the extra C / PAPR caused by R. It is not considered now that the reference to References 4 and 5 is in the PAPR aspect of the existing wood.
- the scheme constructed by the present invention is not RS non-periodic and the C/PAPR caused by the increase in the number of C is reduced. This does not require different physical simplifications in different Cs. In addition, there is no need for subsidy information to mean that all of her are receiving in the analysis without any modification. Therefore, the proposed scheme is to reduce the complete backward compatibility and effective scheme of C PAPR.
- E in TE-A knows the phase and uses phase for D purposes. ERe ease 8 will only use C and the phase will only exist as part of the force. Therefore, the E whose phase is specific to ETReease8 is transparent. That is, the aspects built by the firm are also made for TEReease8.
- C/PAPR is increasing in carrier aggregation.
- the performance of the higher C/PAPR may be caused by an increase in the number of aggregated Cs.
- C /PAPR means looking at higher power amplifiers and larger ones.
- the phase-specific method built by this method reduces C / PAPR to the minimum to limit the power of e B and E without re-receiving the same compatibility.
