Specific embodiment
In 5G system, the function of sweeping wave beam is introduced, and synchronization signal and broadcast channel are with synchronization signal block (SS-
Block mode) is sent.Primary synchronization signal (Primary Synchronization Signal, PSS), secondary synchronization signal
(Secondary Synchronization Signal, SSS) and Physical Broadcast Channel (Physical Broadcast
Channel, PBCH) it is included in synchronization signal block.On analog domain, each synchronization signal block can be regarded as sweeping wave beam (beam
Sweeping the resource of a wave beam during).Multiple synchronization signal blocks form a synchronization signal burst (SS-burst).
Synchronization signal burst can be regarded as containing one piece of resource of the Relatively centralized of multiple wave beams.Multiple synchronization signal burst compositions
One synchronization signal burst set (SS-burst-set).Synchronization signal block repeats to send on different beams, is one and sweeps wave
The process of beam, by sweeping the training of wave beam, user equipment (User Equipment, UE) can be perceived to be received on which wave beam
Signal it is most strong.
Time-domain position of the L synchronization signal block in a 5ms window is fixed, and its index is on time-domain position
Continuously arranged, i.e., from 0 to L-1, therefore emission time and index of the synchronization signal block in the 5ms window are solid
Fixed.
It was found that reference signal (Discovery Reference Signal, DRS) is defined in long term evolution (Long
Term Evolution, LTE) communication system Release 12 agreement in, and because of its macrocyclic characteristic, thus can by with
In the authorization auxiliary access (Licensed Assisted Access, LAA) of LTE, for realizing in unlicensed spectrum
The discovery feature of SCell can also be reduced to the different system such as Wifi system etc of LAA system and shared unlicensed spectrum
Interference.Typically, the duration of DRS is 12 OFDM symbols in a non-empty frame in the access of authorization auxiliary, therefore can
To be further reduced the interference to LAA system and different system.And the DRS in authorization auxiliary access equally includes PSS/SSS/
CRS.Situation there are two types of the appearance opportunitys of DRS in authorization auxiliary access,
The first: user equipment may assume that DRS possibly is present in any subframe in DMTC in authorization auxiliary access,
And user equipment may assume that DRS is appeared in DMTC comprising a PSS in authorization auxiliary access, the of SSS and CRS
In one subframe.That is, user equipment assumes that base station carries out emitting preceding monitoring (Listen Before in DMTC
Talk, LBT), if listening to channel idle, base station sends a DRS in a non-empty frame.
Second: when DRS is transmitted together with PDSCH/PDCCH/EPDCCH in authorization auxiliary access, authorization auxiliary access
Middle DRS may only occur in subframe 0 and subframe 5.That is, if DMTC includes subframe 0 or 5, and user equipment is in son
It needs to detect PDCCH/EPDCCH on frame 0 or 5 or receives PDSCH, then user equipment assumes that DRS only goes out in subframe 0 or 5
It is existing.
With the development of communication technology and the demand in market also gradually exists in the unlicensed spectrum of NR and defines DRS's
Demand, so that the cell in unlicensed spectrum has discovery feature.DRS in NR unlicensed spectrum is needed comprising synchronization signal
