Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, is the schematic flow sheet of the first embodiment of the method for pilot design of the present invention, and in the present embodiment, the method carries out the pilot tone of single measurement to channel for terminal for designing, said method comprising the steps of:
S101, base station requires to determine the resource particle that pilot tone takies to the certainty of measurement of channel according to terminal.
In existing protocol (3GPPTS36.211), when only having an antenna port, the pilot tone of terminal to channel measurement takies a Resource Block (ResourceBlock, be called for short RB) 168 resource particle (ResourceElement, be called for short RE) in 8 (during double antenna port, taking 16), and possess fixing position, be distributed in dispersedly on the diverse location of time-frequency plane (abscissa is time domain, and ordinate is frequency domain).Such pilot density and pattern enough for channel measurement in LTE system, but in the application, terminal will use unlicensed spectrum, and under only carrying out the scene of single measurement, its demand for certainty of measurement is usually above traditional certainty of measurement demand, and therefore traditional pilot density and pattern cannot meet the required precision of channel measurement.Therefore, in the present embodiment, need first to require to determine the RE that pilot tone takies according to the certainty of measurement of channel, such as, need the channel situation detecting the long period, then the density of pilot tone needs to increase, now configurable pilots takies 14 OFDM (OrthogonalFrequencyDivisionMultiplexing in 1 subframe, be called for short OFDM) symbol, thus realize more sampling to channel, it is more accurate to detect the estimation of channel, be beneficial to and promote RRM (RadioResourceManagement, be called for short RRM) validity, be beneficial to the demodulation of data, whether the final idle condition being also just beneficial to terminal judges channel also determines to compete to use this channel.Wherein, RRM target is under band-limited condition, for the terminal in network provides quality of service guarantee, its basic point of departure be network traffic skewness, the characteristic of channel because of channel is weak and interference and in the situations such as fluctuations, the available resources of flexible allocation and dynamic conditioning wireless transmission part and network, farthest improve wireless frequency spectrum utilance, prevent network congestion and keep signaling traffic load little as far as possible.The research contents of RRM mainly comprises following components: power control, channel allocation, scheduling, switching, access control, load control, end to end service quality and adaptive coding and modulating.
S102, the pilot tone of at least Liang Ge community is carried out multiplexing by described base station on frequency domain or in time domain.
Alternatively, because the community at the current place of terminal may possess multiple adjacent area, if terminal needs to carry out cell merge, and when the channel corresponding to community is measured, the words that the measurement of each adjacent area is carried out separately, signaling consumption is larger, and the energy ezpenditure of terminal is also larger, therefore, can the pilot tone of at least Liang Ge community be carried out multiplexing on frequency domain or in time domain, thus just can be transmitted the pilot tone of the community of more than 2 by a RB, thus greatly reduce energy consumption when terminal carries out channel measurement.
And the position of pilot frequency configuration in the embodiment of the present invention can be arranged arbitrarily, pattern also can be arranged arbitrarily, and the RE number taken can be determined according to certainty of measurement demand.Certainly, the district pilots quantity configured in a RB also can be determined according to certainty of measurement demand, and generally speaking, the quantity of district pilots is more, and certainty of measurement is higher.
Such as, in Frequency Division Duplexing (FDD) LTE system, due to the symmetry of frequency channels, can by the pilot frequency configuration of community 1 at the subcarrier of frequency 1 correspondence and with on the subcarrier of frequency 1 symmetry, herein, if on time-frequency plane the subcarrier sequence number of frequency 1 correspondence to be n, n be more than or equal to 1 integer, then the subcarrier sequence number of frequency 1 symmetry is (n+6); By the pilot frequency configuration of community 2 on the subcarrier of frequency 2 correspondence and the subcarrier of frequency 2 symmetry; And in time division duplex LTE system, between the OFDM symbol of frequency 1, time slot (timeslot) or RB, the pilot tone of different districts can be configured successively.
It should be noted that, the district pilots quantity configured in RB can be determined by certainty of measurement demand, and its upper limit can determine with the RE quantity in RB.
S103, the pilot tone pattern formed after the pilot frequency multiplexing of described at least Liang Ge community is sent to described terminal by described base station, so that described terminal completes channel measurement according to described pilot tone pattern.
When base station determines higher than the certainty of measurement demand of traditional measurement the RE quantity that pilot tone takies according to single measurement, and the pilot tone of at least Liang Ge community is carried out on frequency domain or in time domain multiplexing after, just the pilot tone pattern formed after the pilot frequency multiplexing of at least Liang Ge community described in comprising can be sent to described terminal, terminal just can complete the channel measurement at least Liang Ge community according at least two pilot tones in described pilot tone pattern.
Alternatively, also comprise:
The formation rule of pilot tone pattern is sent to described terminal by described base station, so that described terminal determines according to described formation rule the community that each pilot tone belongs to.
Particularly, wireless heterogeneous networks (RadioResourceControl can be passed through in described base station, being called for short RRC) formation rule of described pilot tone pattern sends to described terminal by signaling, medium education (MediaAccessControl, be called for short MAC) signaling or physical layer signaling.
Or the identification information of community can also be configured in pilot tone corresponding to this community by described base station, so that described terminal determines according to the mark of community the community that each pilot tone belongs to.
Like this, terminal, after receiving the pilot tone in RB, just can determine the community corresponding to each pilot tone, then obtains channel conditions corresponding to each community according to pilot measurement.
Alternatively, if the pilot tone of at least Liang Ge community is carried out multiplexing by described base station on frequency domain or in time domain, then the time-domain resource that takies of each pilot tone is continuous.Wherein time-domain resource is OFDM symbol.
Continuous print OFDM symbol makes the sampling of channel possess temporal continuity, makes the measurement of channel quality more accurate.And in embodiments of the present invention, time multiplexing on frequency domain, can configure each pilot tone and take a subframe i.e. 14 OFDM symbol, the continuous sampling of such long period can promote the accuracy of channel quality measurement further.
Certainly, also can configure each pilot tone and take and be less than 14 OFDM symbol, specifically can determine according to channel measurement accuracy requirement, and the symbol quantity that each pilot tone takies can be the same or different, the embodiment of the present invention is not limited in any way.
It should be noted that, in embodiments of the present invention, the pilot tone of each community can also carry out adjusting and changing, then in terminal of issuing a notice according to the change of the channel measurement required precision of terminal.Such as, current certainty of measurement requires higher, therefore need to take continuous print 14 OFDM symbol, and after certainty of measurement requires to reduce, base station also can adjust pilot tone corresponding to this cell channel, make it take 10 OFDM symbol and just can meet the current certainty of measurement requirement of terminal, thus save a part of Measuring Time.
Require to determine the resource particle that pilot tone takies to the certainty of measurement of channel according to terminal, and the pilot tone of at least Liang Ge community is carried out on frequency domain or in time domain multiplexing after, the pilot tone pattern generated after the pilot frequency multiplexing of described at least Liang Ge community is sent to terminal, thus makes terminal can complete channel measurement according to described pilot tone pattern.Owing to adding the density of pilot tone according to the high-precision requirement of single measurement, thus ensure that the precision of channel measurement, and the pilot tone of at least Liang Ge community is carried out on frequency domain or in time domain multiplexing after, the energy ezpenditure that terminal measures the channel of multiple community can be reduced, improve the efficiency of channel measurement, be convenient to select cell merge rapidly after terminal knows the channel quality of multiple community, thus improve the business experience of user.
