Description
Technical field
The present invention relates to communication technical field, filled in particular to a kind of beam configuration method and a kind of beam configuration
Put.
Background technology
In traditional LTE (Long Term Evolution, Long Term Evolution) system, it is all single beam that base station sends
(wave beam) sends, and antenna is omnidirectional, because carrier frequency is low, coverage is enough big.
But in NR (New Radio, new wireless technology), using under high frequency situations, high-frequency path is lost, penetration loss
Etc. larger, but coverage is smaller, then in order to expand the coverage area, base station needs to use the sending method of multiple beam, i.e., together
One time concentrated on a beam all transmit powers, and a beam only covers a direction within a unit interval,
Such as using the beam in the direction of 90 degree of covering, then need beam polls within 4 unit interval to scan, realize 360
The covering of degree, such covering radius can increase.But it is understood that if omnidirectional sends, then while just covering whole
Individual direction, if being based on beam, each beam direction is needed in different time polls, can so bring time delay, that is,
Say, if to cover whole cell, each beam width is narrower, i.e. the angle of each beam coverings is smaller, then to complete 360
Degree covering, it is necessary to sweep time it is more long, and the covering radius in each beam direction is bigger, i.e., the user under this beam direction
The signal for receiving is stronger, but the time cycle that user wants to receive the signal of the beam is bigger.
In addition, in terms of mobile management, such as user measures the signal intensity of adjacent cell and this cell and is compared,
When further determining whether to need to carry out cell to switch, due in traditional LTE system because being all that omnidirectional sends, each cell
Only one of which signal, then only need to measure this signal and carry out the comparing between cell.When there is multiple in NR
During beam directions, and the multiple signals of measurement which or which are needed, and how to formulate the criterion of cell switching, it is necessary to further beg for
By and determine.
And, for the reference signal MRS measured for RRM or mobile management, if matched somebody with somebody using difference
The wave beam put is transmitted, then using the cell selection criterion or handoff algorithms of traditional LTE system, that is, be based only upon reception
Signal intensity or received signal quality come if selection target cell to will be unable to select best Target cell.Because for two
The transmit power of the identical MRS reference signals that individual base station, such as base station 1 and base station 2, base station 1 and base station 2 use, Er Qieji
Stand 1 from user terminal closer to but because the beam width that base station 2 uses is narrower, finally causing that the result of user terminal measurement shows
Show that the signal intensity of the base station 2 that user receives is most strong, so user terminal selecting base station 2 is used as target BS.But work as
User terminal is switched to after base station 2, discovery want being serviced, it is necessary to wait time it is very long cause handling capacity reduce because
Beam narrow widths.But if taking into account beam configuration informations in selection target cell, then can accordingly increase signaling and hold
Pin and complexity.
