A kind of information processing method, device and system
Technical field
The present invention relates to the communication technology more particularly to a kind of information processing methods, device and system.
Background technique
In high-frequency communication, transmitted due to using higher carrier frequency, then average path loss can be than tradition Long term evolution (Long Term Evolution, LTE) system it is much larger, transmitted for example, by using the carrier frequency of 28GHz, benefit With formula:
The average proportions information of high frequency circuit loss value Yu LTE circuit loss value is calculated are as follows:
In order to guarantee to cover in high-frequency communication, i.e., receiving side meets minimum signal and interference plus noise ratio (Signal To Interference plus Noise Ratio, SINR) it requires, need raising to send and receive machine gain.
Wherein, R is the radius of MPS process, and λ is the wavelength of corresponding carrier wave, GtFor transmission antenna gain, GrFor receiving antenna Gain.
LTE communication demand peak demand reaches the region of covering 100km, if covered according to highest, only considers average Path loss (depletion region), then the region for covering up to 1km can be considered in high-frequency communication highest.If it is considered that practical high frequency carrier High-altitude aspiration degree (oxygen absorption, rain decline, mist decline) and it is sensitive for shadow fading the features such as, can actually support Covering be less than 1km.
If high-frequency communication supports maximum 1km covering, compared with LTE system, what identical overlay area can obtain SINR is than different, the former declines than the SINR that the latter has at least 20dB, in order to guarantee high-frequency communication and LTE system coverage area It is interior that there is approximate SINR, need to guarantee the antenna gain of high-frequency communication.At this moment fortunately, since high-frequency communication has Shorter wavelength thereby may be ensured that and accommodate more antenna elements on unit area, more antenna elements can provide more High antenna gain, to guarantee the covering performance of high-frequency communication.
More antenna elements mean to guarantee the covering of high-frequency communication using the method for beam shaping.By LTE Previous design philosophy it is found that the beam shaping effect to be got well needs accurately to obtain the status information of channel, thus The weight of beam shaping is obtained from the status information of channel.And preferable beam shaping weight is obtained, for transmitting terminal base station For, receiving end terminal needs the channel state information or weight of feeding back downlink, and for receiving end, transmitting terminal base station is needed The channel state information or weight of feeding back uplink are wanted, thus guarantee that base station can send downlink business using optimal wave beam, Terminal can also send uplink service using the optimal wave beam for meeting ad hoc rules.At this moment it will have a problem that: base station It, can not be using optimal wave cover to receiving end, so that receiving end is unable to measure the reference of base station transmission before obtaining weight Signal measures, or even if base station covers terminal, but terminal is unable to reach the same covering of base station, feedback it is interior Holding base station can not know, so that the selection and normal communication of wave beam weight can not be carried out.
