Description
Technical field
The present invention relates to wireless communication technology field, a kind of reference signal configuration, sending method, base station, end are particularly related to
End, computer readable storage medium.
Background technique
In the base station end and terminal antenna model of cordless communication network high band, there is mutiple antennas panel.It is multiple
On aerial panel, antenna element inside each aerial panel, which may be considered, has been calibrated, and the antenna array between aerial panel
Son may not calibrated completely.During multi-beam operation, it is 5G system that how mutiple antennas panel, which carries out wave beam forming,
In a major issue.
When between aerial panel antenna element calibration do enough to it is good when, as shown in Figure 1, the antenna element of mutiple antennas panel
It can regard as and constitute a bigger antenna, such mutiple antennas panel can carry out united beam form-endowing, by mutiple antennas
The power of panel merges, and the wave beam figuration gain with higher of institute's figuration, beam angle is also relatively narrow, and whole bandwidth
On be all limited to the beam direction.
On the other hand, as shown in Figures 2 and 3, each aerial panel can also carry out independent wave beam forming, due to single
Antenna array subnumber antenna array subnumber more united than mutiple antennas panel on aerial panel is few, therefore obtained wave beam forming increases
Benefit can be lower than the gain of multiple antennas panel joint figuration, and beam angle is also wider, but the wave beam forming within the scope of whole bandwidth
It is more flexible.
Other than combining completely with completely self-contained multiple antennas panel beamforming operation, in fact in NR (wireless access
Technology) in, in order to realize more flexible SU (single user) and MU (multi-user) transmission, PDSCH (Physical Downlink Shared Channel)
It should be able to support flexible multiple antennas plane transport, according to channel condition and SU, MU dispatch situation, base station can determine each
Aerial panel sending method used in PDSCH in subframe or time slot, i.e., flexible more and/or some antennas panel joint
And/or independent beam figuration.
In NR, at least synchronization signal SS of signal existing for periodicity (transmission in synchronization signal block (SS block),
Including NR-PSS (primary synchronization signal), NR-SSS (secondary synchronization signal) and NR-PBCH (Physical Broadcast Channel)), as shown in figure 4,
PDSCH and SS block1, periodical CSI-RS (channel state information reference signals) 2, semi-static CSI-RS3 is in distinct symbols
Upper multiplexing.Since NR-SSS is used in the RRM of IDLE (Idle state) user (wireless resource management measurement) in the prior art,
Need to guarantee that the power of NR-SSS is consistent in all subframes, that is, the aerial panel number needs for being used for transmission SS block are
One fixed value, since the aerial panel of transmission SS block cannot transmit CSI-RS, the antenna of transmission of reference signals again
Panel number is limited the aerial panel number by transmission SS block, is generally also configured as a fixed value, is caused with reference to letter
Number transmission power be restricted, be unable to flexible configuration.
