Description
Technical field
The present embodiments relate to the communication technology, more particularly to a kind of triggering method of aperiodic reference signal and
System.
Background technology
In LTE (Long Term Evolution, Long Term Evolution) network, eNodeB (Evolved Node
B, evolved Node B) a part of region of generally distribution system bandwidth gives specific UE (User
Equipment, user equipment).Resource i.e. in a special time to UE distribution specific frequency areas.
Now, if eNodeB detects that the quality of the specific frequency area of which part is preferable, can preferentially distribute to
UE is to improve UE quality of service.In eNodeB scheduling process, RS (Reference Signal,
Reference signal) play main function.The reference signal is broadly divided into uplink reference signals and downlink reference signal,
Wherein, uplink reference signals refer to the signal sent from UE to eNodeB, i.e. transmitting terminal is UE receiving terminals
For eNodeB；Downlink reference signal refers to the signal sent from eNodeB to UE, i.e. transmitting terminal is eNodeB
Receiving terminal is UE.
Include 5 kinds of signal types, wherein CSI-RS (Channel Status in downlink reference signal
Information Reference Signal, channel state information reference signals) it is introduced into R10, it is logical
Lax punching is transmitted to obtain channel status on the user's transmission channel crossed in specific sub-frame, and it is mainly used
In the measurement of down channel quality and down channel estimation (the relevant detection and demodulation that are used for UE ends).With
The development of the communication technology, two kinds of CSI-RS is introduced in R13, one kind is non-precoded
CSI-RS, full MPS process is realized by the broad beam of same widths, can be configured to multiple UE in cell
Reference signal；Another kind is beam forming CSI-RS, using the mode of beam forming by multiple bays
It is mapped in a CSI-RS port, forms the narrow beam with certain orientation, can only be inside coverage cell
Subregion.
In order to improve CSI-RS resource efficiency, resource overhead is reduced, acyclic CSI-RS can be introduced,
But do not have a kind of mode that can rationally trigger aperiodic CSI-RS in the prior art to cause resource efficiency
Improve, expense is reduced.
The content of the invention
The invention provides a kind of triggering method and system of aperiodic reference signal, is improved realizing
While CSI-RS efficiency, aperiodic CSI-RS can be triggered for multiple user equipmenies simultaneously, reduced
Aperiodic CSI-RS triggering signaling, reduces signaling consumption.
In a first aspect, the embodiments of the invention provide a kind of triggering method of aperiodic reference signal, including：
Network side equipment sends identification information and index information to user equipment, and is the user device configuration
The resource allocation information of aperiodic reference signal；
If the user equipment detects the Downlink Control Information scrambled with the identification information, according to
Index information judges whether that needs receive and detect the aperiodic reference signal, wherein, under the scrambling
Row control information includes the trigger command of the aperiodic reference signal of at least two user equipmenies.
Second aspect, the embodiment of the present invention additionally provide a kind of triggering system of aperiodic reference signal, including：
Configuration module, for sending identification information and index information to user equipment, and it is the user equipment
Configure the resource allocation information of aperiodic reference signal；
Trigger module, if detecting that the descending control scrambled with the identification information is believed for the user equipment
Breath, then judge whether to need to receive according to the index information and detect the aperiodic reference signal, wherein,
The Downlink Control Information of the scrambling includes the triggering life of the aperiodic reference signal of at least two user equipmenies
Order.
The present invention sends identification information and index information to user equipment by network side equipment, and is the use
The resource allocation information of the aperiodic reference signal of family device configuration, if the user equipment is detected with the mark
Know the Downlink Control Information of information scrambling, then judge whether to need to receive and detect institute according to the index information
Aperiodic reference signal is stated, solution wishes to introduce into aperiodic CSI-RS in the prior art, to improve BF
CSI-RS efficiency, CSI-RS resource overhead is reduced, and meet flexibly calibration BF CSI-RS ripples
Shu Fangxiang demand, the problem of a kind of no rational method triggering aperiodic CSI-RS, carried realizing
While high CSI-RS efficiency, aperiodic CSI-RS can be triggered for multiple user equipmenies simultaneously, subtracted
