Description
Technical field
The present invention relates to the communications field, in particular to a kind of communication beams selection method, device and terminal.
Background technology
Among antenna is applied to any one radio system as the component for radiating or receiving radio wave, effect
It is that the high-frequency current (or guided wave) for sending transmitter is effectively converted into radio wave and is transmitted to specific area of space；Or
The radio wave that specific area of space sends over is effectively converted into high-frequency current and enters receiver by person.The former is known as
Transmitting antenna, the latter are known as reception antenna, this depends on the functional requirement of radio system.
Antenna beam pattern is the mutual pass of any position in energy and space for describing to be given off by antenna
System can learn the electromagnetic wave radiated by antenna the relative intensity of each position or absolutely in space by directional diagram
To intensity.Unquestionably, the horizontal directivity pattern requirement of antenna for mobile phone is omnidirectional, and actually the beam pattern of antenna for mobile phone is simultaneously
Inessential, mainly during the use of mobile phone, the radiation characteristic of antenna for mobile phone and the radiation characteristic of single antenna are not at this time
Identical.The directional diagram of antenna for mobile phone only requires that horizontal plane is approximately omnidirectional.
However as being constantly progressive for radiotechnics, various radio traffics emerge in multitude, and wireless electric industry
The relied on frequency spectrum resource of business is limited, and bandwidth demand is continuously increased in face of people, what traditional business correspondence used
There is extremely nervous situation in frequency spectrum resource between 300MHz~3GHz, can not meet the needs of future wireless system.
In following 5G wireless communications, it will communicated, such as 28GHz, 45GHz etc. using higher carrier frequency
Have that Free propagation loss is larger, and easily by oxygen absorption, being declined by rain influences the shortcomings of big, serious shadow Deng, this high frequency channel
The covering performance of high frequency communication system has been rung, compared with LTE system, the SINR ratios that identical overlay area can obtain are different,
The SINR that the former has at least 20dB than the latter declines, in order to ensure that high-frequency communication is approximate with having in LTE system coverage area
SINR, need ensure high-frequency communication antenna gain.Since the corresponding carrier frequency of high-frequency communication has shorter wavelength, institute
With can be can accommodate more antenna elements on guarantor unit's area, and more antenna elements mean that wave beam tax may be used
The method of shape improves antenna gain, so as to ensureing the covering performance of high-frequency communication.
After the method for wave beam forming, transmitting terminal can concentrate emitted energy in one direction, and in other sides
Upward energy very little does not have, that is to say, that each wave beam has the directionality of itself, and each wave beam can only cover centainly
Terminal on direction, transmitting terminal, that is, base station, which needs to emit multiple wave beams, could complete to cover all around.When base station is a direction
On terminal send downlink information when, will use corresponding beams carry, and receiving terminal, that is, terminal need carry out receiving terminal
Wave beam forming, realize directional reception, and then improve receiving antenna gain.Communicating pair is real by initial wave beam training process
The alignment of transmitting-receiving wave beam is showed, initial beam training process is a relatively very long process, to obtain best wave beam training effect
Fruit needs to traverse all transmitting-receiving wave beams pair, to find the transmitting-receiving beam direction of best performance as communication beams.
But in communication process, due to the movement of terminal, transmitting-receiving wave beam will will appear variation, typically such as due to the rotation of terminal
Turn, former uplink preferred emission wave beam and downlink preferably receive wave beam and will change, if terminal is still preferred using former uplink
Launching beam sends upstream data to base station, and base station will be unable to receive, corresponding, and terminal preferably receives wave beam by downlink
The downlink data of base station can not be received.If associated change can not quickly be found, and identify new preferred transmitting-receiving wave beam,
Service disconnection is would potentially result in, seriously affects communication quality of the terminal in high-frequency communication.
For the problem of terminal movement causes communication quality poor in the relevant technologies, there is presently no efficiently solve scheme.
