Specific embodiment
Compared with previous mobile communication system, the following 5G (the 5th Generation Mobile Communication System) needs to adapt to more diversified
Scene and business demand.The prevailing scenario of NR (New Radio, new wireless) include eMBB, extensive Internet of Things (mMTC),
URLLC, these scenes propose highly reliable, low time delay, big bandwidth, wide covering etc. to system and require.For the industry of certain scenes
Business, it is desirable that low delay and highly reliable transmission.
URLLC business has the characteristic of high priority and low time delay, and the duration transmitted in time is shorter, when in order to reduce
Prolong, while using biggish bandwidth or biggish subcarrier spacing on frequency domain, meets handling up for URLLC business.In order to guarantee
The requirement of the high priority and low time delay of URLLC business, base station, can be by the data transmission schedulings of URLLC in descending scheduling
In traditional business, as eMBB business datum transfer resource on.This URLLC business uses the row of the transfer resource of eMBB business
To be called preemption (preemption).Base station can pass through descending control signaling, such as preemption indication (preemption
Instruction) or UE-specific (UE is dedicated) DCI (Downlink Control Information), which running time-frequency resource of UE or which scheduling notified
Data block is camped on.
Downlink measures relevant reference signal: CSI-RS (channel state information reference symbol), TRS (Tracking
Reference Signal, track reference signal)
(1)CSI-RS
CSI-RS is used to obtain CSI by UE, and DMRS (believe by Demodulation Reference Signal, demodulation reference
Number) it is used for channel estimation.Compared with the specific reference signal of cell (can also be used for obtaining CSI), the time-frequency density of CSI-RS
It is lower, therefore expense is smaller.
CSI-RS has the CSI-RS (non-zero-power CSI-RS) and zero energy CSI-RS (zero- of non-zero power
Power CSI-RS) point.The CSI-RS of non-zero power sends real CSI-RS on the RE (resource unit) that it is occupied, i.e.,
There is transmission power on corresponding RE.Non-zero power CSI-RS does not send anything on the RE that it is occupied.
Only the transmission on distributing to those of corresponding UE RB is different from DMRS, and CSI-RS is the entire downlink system bandwidth of covering
, eMBB PDSCH (Physical Downlink Shared Channel) should explicitly avoid those by the occupied RE of CSI-RS in mapping.
Zero-power (ZP) CSI-RS and normal non-zero-power (NZP) CSI-RS have identical structure, but
ZP CSI-RS does not send any reference signal on corresponding RE.
Purpose is:
A, UE is enabled to receive the CSI-RS from neighbor cell, and the CSI-RS not will receive the transmission in this cell
Strong jamming.The CSI of neighbor cell is measured for supporting multiple cell transmission technology, such as CoMP is good.
B, the interference to the CSI-RS transmission of neighbor cell is reduced.This is particularly suitable for heterogeneous network (heterogeneous
Network) in deployment, the cell of different capacity overlaps on same frequency spectrum at this time, forms the cell layer of overlapping.
It briefly, is exactly that neighbor cell has sent CSI-RS on which RE, corresponding RE is just arranged to by this cell
ZP CSI-RS's, to avoid interference.
(2) track reference signal (Tracking Reference Signal, TRS)
User equipment according to primary synchronization signal (Primary Synchronization Signal, PSS) with it is auxiliary synchronous
After signal (Secondary Synchronization Signal, SSS) reaches synchronous, it is also necessary to channel carry out time-frequency with
Track (Time/Frequency Tracking).Reference signal for time-frequency tracking is known as track reference signal.For TRS's
Design, 3GPP RAN1 working group concentrate and have discussed.
The function of TRS, which can divide, is independent two aspects:
Temporal tracking and delay spread estimation: following range depends on the frequency domain density of TRS, and tracking accuracy depends on TRS
Frequency domain bandwidth.
Frequency domain tracking and doppler spread estimation: following range depends on the time domain density of TRS, and tracking accuracy depends on
The time domain period of TRS.
