Description
Technical field
The present invention relates to field of communication technology, more particularly to a kind of sending method of Sounding Reference Signal, device,
Terminal and base station.
Background technique
Uplink reference signals are divided into two classes: one kind is demodulated reference signal, with PUSCH (Physical Uplink
Shared Channel, physical uplink shared channel) or PUCCH (Physical Uplink Control CHannel,
Physical uplink control channel) simultaneous transmission, for the demodulation of data, another kind of is SRS (sounding reference
Signal, Sounding Reference Signal), it is mainly used for channel quality estimation, in order to which base station carries out frequency selective scheduling, separately
On the one hand it can be used for power control enhancing or support the various function of initializing of the currently also unscheduled UE arrived, such as initially
Change modulation and encoding scheme selection, initialization power control, timing advance and frequency semi-selective scheduling etc..Therefore, it is not
Must be transmitted together with any physical channel, if transmitted together with physical channel, such as PUSCH, SRS may occupy it is different,
Often bigger bandwidth.
In LTE, the SRS transmission of two classes is defined,
One kind is periodical SRS (periodic SRS, corresponding triggering type trigger type 0): 3GPP (3rd
Generation Partnership Project, third generation partner program) protocol version Rel-8 in introduce, base station
ENB is passed by the SRS that RRC (Radio Resource Control, wireless heterogeneous networks) signal deployment terminal UE carries out single
Defeated or periodic transmission SRS stops to send request until receiving.The period that SRS is sent can be 2,5,10,20,40,80,
160 or 320ms.
Another kind of is aperiodicity SRS (aperiodic SRS, corresponding triggering type trigger type 1): 3GPP's
It is introduced in protocol version Rel-10, that is, introduces the mode of Dynamic trigger SRS a kind of.For FDD (Frequency Division
Dual, frequency division duplex), eNodeB can pass through DCI (Downlink Control Information, that is, Downlink Control Information)
Format 0/4/1A triggers UE and sends aperiodicity SRS.For TDD (Time Division Duplexing, time division duplex),
ENodeB can trigger UE by DCI format 0/4/1A/2B/2C/2D and send aperiodicity SRS.The mode of triggering is to make
With the SRS request field in DCI.
Though for periodically or the configuration information of aperiodicity SRS, SRS, such as bandwidth, period and subframe
Offset (subframe sent for determining SRS), Duration (instruction is to send single or period transmission), bandwidth, frequency domain
Initial position, whether frequency hopping, transmission the comb teeth Transmission Comb (K that instruction usesTCValue), Cyclic Shift (refers to
Show cyclic shift), port number etc. be to be configured by RRC signaling.
With the introducing of 3D-MIMO (Multiple-Input Multiple-Output, Multiple Input Multiple Output), antenna
Number becomes more, can be simultaneously using the directionality of vertically and horizontally dimension, so that more terminal multiplexings, the sky of He Geng great layer
Between be multiplexing into possibility;SRS in order to support the spatial reuse of the more layer in more multiple terminals, for terminal channel information acquisition
It is also required to be enhanced, the enhanced scheme of the SRS discussed in existing standardization includes:
It is being not used by PUSCH DMRS (Demodulation Reference Signal, demodulated reference signal) money
SRS is transmitted on source;
In PUSCH transmitted over resources SRS;
Increase the number of SRS comb to be multiplexed more terminals
4Tx antenna switching transmission SRS
Precoding SRS
Increase SC-FDMA (the Single-carrier Frequency that SRS transmission is used in ascending pilot frequency UpPTs
Division Multiple Access, single-carrier frequency division multiple access) quantity
Above-mentioned enhancing focuses primarily upon the transmission resource for increasing SRS, so as to send SRS for more terminals, separately
It on the one hand also include that the SRS of uplink more antennas is supported to send.
However, the triggering mode of SRS only triggers two kinds by high-level signaling triggering and DCI, wherein for high-level signaling
The mode of triggering needs to carry out to reconfigure transmission single or periodic SRS by the RRC signaling of some cycles.When only
Need transient channel information without knowing long-term information in the case where, single configuration real-time it is poor.
For aperiodic triggering mode, several format of triggering mean to need for UE uplink or
Downlink transfer could trigger aperiodic SRS;
Existing high-level signaling scheduling mode needs to wait the transmission of RRC signaling, and aperiodic triggering mode needs end
End has data scheduled.
