Description

A kind of methods, devices and systems realizing downlink wave beam index process

Technical field

The present invention relates to the Long Term Evolution AS (Long term evolution advanced system, LTE-Advanced) of the communications field, particularly relate to a kind of methods, devices and systems realizing downlink wave beam index process.

Background technology

When HF communication, transmit owing to have employed higher carrier frequency, so average path loss can be more much larger than traditional LTE system, such as, adopt the carrier frequency of 28GHz to transmit, utilize formula:

L_{f} = {(\frac{4 πR}{λ})}^{2}

The average proportions information calculating high frequency circuit loss value and LTE circuit loss value is:

L_{H} / L_{L} = {(\frac{4 πR}{λ_{H}})}^{2} / {(\frac{4 πR}{λ_{L}})}^{2} = {(\frac{λ_{L}}{λ_{H}})}^{2} \approx 100

In order to ensuring coverage in HF communication, namely receiver side meets minimum SINR requirement, needs to improve to send and receiver gain.

P_{r} = P_{t} G_{t} G_{r} {(\frac{λ}{4 πR})}^{2} = P_{t} G_{t} G_{r} / L_{f}

Wherein, R is the radius of MPS process, and λ is the wavelength of corresponding carrier wave, G _tfor transmitting antenna gain, G _rfor receiving antenna gain.

The peak demand of LTE communication demand reaches the region covering 100km, if according to the highest covering, only consider average path loss (depletion region), so HF communication is the highest can consider to cover the region reaching 1km.If consider actual high frequency carrier high absorption of air degree (oxygen absorption, rain declines, mist decline etc.) and for features such as shadow fading are responsive, the actual covering that can support is less than 1km.

If HF communication supports that maximum 1km covers, compared with LTE system, the SINR that identical overlay area can obtain is than different, the signal to noise ratio that the former exists at least 20dB than the latter declines, in order to ensure, in HF communication and LTE system coverage, there is approximate SINR, need the antenna gain ensureing HF communication.At this moment fortunately, because HF communication has shorter wavelength, thus guarantor unit's area can hold more antenna element, more antenna element can provide higher antenna gain, thus ensures the covering performance of HF communication.

More antenna element means the mode of beam shaping can be adopted to ensure the covering of HF communication.The design philosophy previous from LTE, the beam shaping effect that expected needs the state information accurately obtaining channel, thus from the state information of channel, obtain the weights of beam shaping.And obtain good beam shaping weights, for the base station as transmitting terminal, terminal as receiving terminal needs channel condition information or the weights of feeding back downlink, for receiving terminal, transmitting terminal needs channel condition information or the weights of feeding back uplink, thus ensureing that base station can adopt optimum wave beam to send downlink business, the wave beam of the optimum that terminal also can adopt sends uplink service.At this moment such problem will be there is: base station is before acquisition weights, optimum wave cover cannot be utilized to receiving terminal, thus receiving terminal cannot be measured the reference signal that base station sends, even if or base station coverage is to terminal, but terminal cannot reach the same covering of base station, the content base station of feedback cannot be known, thus can not carry out selection and the proper communication of wave beam weight.
