On this basis, inventor further devises how user equipment specifically accuses the result for sweep wave beam training
Know the process step of base station.
To more fully understand those skilled in the art and realizing the present invention, referring to the drawings, pass through specific embodiment
It is described in detail.
Embodiment one
As described below, the embodiment of the present invention provides the processing method of a kind of pair of downlink signal.
Firstly, the processing method to downlink signal in the present embodiment, the unlicensed spectrum suitable for 5G system
In (Unlicensed band).
As previously mentioned, in 5G system, synchronization signal, broadcast channel be sent in a manner of synchronization signal block, and
Introduce the function of sweeping wave beam.
Primary synchronization signal, secondary synchronization signal and Physical Broadcast Channel are in synchronization signal block.Each synchronization signal block can be with
Regard the resource of a wave beam during sweeping wave beam as.Multiple synchronization signal blocks form a synchronization signal burst.Synchronous letter
Number burst can be regarded as containing multiple wave beams Relatively centralized one piece of resource.Multiple synchronization signal bursts composition one are same
Walk signal burst set.Synchronization signal block repeats to send on different beams, is the process for sweeping wave beam.User equipment can
By sweeping the training of wave beam, it is most strong to perceive the signal received on which wave beam.
Time-domain position of the L synchronization signal block in a 5ms window is fixed.The index of L synchronization signal block exists
Be on time-domain position it is continuously arranged, from 0 to L-1.Therefore emission time of the synchronization signal block in this 5ms window is
Fixed, index is also fixed.
Discovery reference signal (Discovery Reference Signal, DRS) is defined in LTE Release 12,
For user equipment to the synchronization (time-frequency tracking) of SCell (Secondary Cell) and measurement, it is properly termed as " the hair of SCell
It is existing " function.It is that DRS is long period signal using the benefit of DRS, long period signal is smaller to the interference of whole network.
DRS is by PSS/SSS/CRS (Cell-specific Reference Signal, cell specify reference signal) group
At.For FDD system, the DRS duration (Duration) is 1 to 5 continuous subframes (subframe)；For TDD system,
The DRS duration is 2 to 5 continuous subframes.The launching time of DRS is by DMTC (Discovery Measurement Timing
Configuration, the configuration of discovery time of measuring) it defines, user equipment assumes that DRS occurs once in each DMTC.
In the authorization auxiliary access (Licensed Assisted Access, LAA) of LTE, DRS just can be used for non-
The discovery feature for authorizing the SCell on frequency spectrum is advantageously reduced to LAA system and is shared unauthorized because of its long period characteristic
The interference of the different system (such as Wifi system) of frequency spectrum.The duration of LAA DRS is 12 OFDM symbol in a non-empty frame
Number, to be further reduced the interference to LAA system and different system.LAA DRS equally includes PSS/SSS/CRS.
In general, the appearance opportunity of LAA DRS, there are two types of situations:
Situation one: user equipment may assume that LAA DRS possibly is present in any subframe in DMTC, and user sets
It is standby to may assume that LAA DRS is appeared in DMTC comprising a PSS, in first subframe of a SSS and CRS.That is,
User equipment is assumed: base station carries out emitting preceding monitoring (Listen Before Talk, LBT) in DMTC, if listening to letter
Road is idle, then base station sends a DRS in a non-empty frame.
Situation two: when LAA DRS is transmitted together with PDSCH/PDCCH/EPDCCH, LAA DRS may be only in 0 He of subframe
Subframe 5 occurs.That is, if DMTC includes subframe 0 or 5, and user equipment needs to detect in subframe 0 or 5
PDCCH/EPDCCH receives PDSCH, then user equipment assumes that DRS only occurs in subframe 0 or 5.
In the unlicensed spectrum of 5GNR, it is also desirable to DRS is defined, so that the Cell in unlicensed spectrum has discovery feature
With the function of wave beam training.DRS is usually downlink signal, can train downlink wave beam and downlink reception wave beam, the application
In, user equipment can (i.e. which downlink wave beam be that user equipment feels best by the training result of downlink wave beam
) informing is to base station.
To the processing method flow chart of downlink signal shown in referring to Fig.1:
S101, from the signal detected in the downlink signal sent by base station in DRS.
In unlicensed spectrum, from the signal detected in the downlink signal sent by base station in DRS.
S102 is measured according to the signal in the DRS detected, determines the downlink beam index of selection.
It when detecting the signal in DRS, is measured according to the DRS detected, determines the downlink wave beam of selection
Index.
S103, into the launch time window of instruction information.
When detecting the signal in DRS, after the end time of the time window of the end time or DRS of DRS, open
Dynamic timing, enters the launch time window of instruction information after preset time.
The instruction information is used to indicate the selected downlink beam index of the user equipment to base station.
By above to the description of technical solution it can be seen that in unlicensed spectrum, user equipment is worked as in the present embodiment
After detecting DRS, by sweeping wave beam training, the signal that perception receives on which wave beam is most strong, and will sweep wave beam training
As a result it is sent to base station, so as to obtain better communication service from base station, improves communication efficiency.
Referring to the processing method flow chart shown in Fig. 2 to downlink signal, it is described in detail below by way of specific steps:
S201, from the signal detected in the downlink signal sent by base station in DRS.
In unlicensed spectrum, user equipment from the downlink signal sent by base station detect DRS in signal.
Wherein, " signal in DRS " is some signal for being used to measure in DRS, such as synchronous block, and the survey
Measure the corresponding downlink wave beam of signal.
DRS is sent in the time window of DRS, wherein " time window of DRS " is to detect DRS's for user equipment
One complete time window.The time window of DRS is generally configured by high level.The time window of DRS can be defined by DMTC,
It can be by SMTC (Synchronization signal Measurement Timing Configuration, synchronization signal survey
Amount timing configured) either define in other ways.
When detecting signal in DRS, into subsequent step S202 and step S203 (and step S204a, step
S204b), or can also skip step S203 (and step S204a, step S204b).
S202 is measured according to the signal in the DRS detected, determines the downlink beam index of selection.
Wherein, the downlink beam index indicates downlink wave beam optimal within each period.
The unlicensed spectrum is the unlicensed spectrum in 5G system, synchronization signal, wide as previously mentioned, in 5G system
Broadcasting channel is sent in a manner of synchronization signal block, and therefore, the downlink beam index can be about synchronization signal
The index of block.
In addition, in other embodiments, it, can be at the time window end of DRS if user equipment fails to detect DRS
After preset time z after only, into the launch time window of instruction information, to indicate the selected downlink hair of the user equipment
Penetrate beam index.
Since in the system based on wave beam, the signal in DRS is sent in a manner of sweeping wave beam, therefore, Yong Hushe
The standby signal that may can not be detected on certain beam transmission opportunitys in DRS.Moreover, because DRS is in launch time window domestic demand
It does first to listen and send out afterwards, therefore, there is randomness and sudden at the beginning of DRS.So user equipment is needed according to other letters
It ceases to infer the end time of the end time of DRS or the time window of DRS.
Wherein, " end time of DRS " is in DRS at the beginning of time for being sent completely of all signal/channels or DRS
Between time for obtaining plus the DRS duration.Wherein, start the time sent " at the beginning of DRS " for DRS.In general,
At the beginning of " end time of DRS " and DRS " all in " time window of DRS ".In general, " at the beginning of DRS "
At the beginning of needing not be equal to " time window of DRS ", " end time of DRS " needs not be equal to " time window of DRS "
End time, that is to say, that transmission of the DRS in " time window of DRS " has certain randomness and sudden.
In specific implementation, a kind of method is: where PCell (Primary Cell, main plot) and unlicensed spectrum
When SCell (Secondary Cell, secondary cell) is synchronous, user equipment obtains DRS by the timing information of PCell
Time window at the beginning of, then according to the timing or time index information carried on the DRS on SCell, such as synchronous letter
The time index of number block, to infer the end time of the end time of DRS or the time window of DRS.
Another method is: in no PCell auxiliary, user equipment according to the timing carried on the DRS on SCell or
Time index information and DRS delay send information, to infer the end time of the end time of DRS or the time window of DRS.
It can usually infer the end time of DRS or the time of DRS in which way come designated user's equipment by base station
The end time of window.
It is understood that step S202 and step S203 (and step S204a, step S204b) completely can be simultaneously
It carries out, not inevitable precedence relationship.
S203, judge user equipment whether have the ability in preset time y complete DRS measurement.
If it is, subsequent step S204a is executed, if it is not, then executing subsequent step S204b.
It should be noted that each preset time involved in the present embodiment, for example, preset time x1, preset time x2,
Preset time y, preset time z etc. are to start to calculate using the termination time of the signal in the DRS detected as starting point.
It is understood that step S203 (and step S204a, step S204b) is optional step.Even not into
In the case where row step S203 (and step S204a, step S204b), subsequent step S205 still can be executed.
S204a enters the launch time window of instruction information after preset time x1.
User equipment judges whether user equipment has the ability to complete DRS in preset time y in step S203 previous
Measurement.
If it is, sending out (Listen Before Talk, LBT) afterwards without first listening, enters after preset time x1 and refer to
Show the launch time window of information.
Wherein, preset time y is less than or equal to preset time x1.
In a particular embodiment, the preset time x1 can be 16 microseconds or 25 microseconds or 1 OFDM symbol when
A prefixed time interval long or by high level configuration.
For example, can be the preset time x1 is 25 microseconds, and the preset time y is 16 microseconds.
S204b is first listened after preset time x2 and is sent out afterwards, if listening to channel idle, is entered the instruction and is believed
The launch time window of breath.
User equipment judges whether user equipment has the ability to complete DRS in preset time y in step S203 previous
Measurement.
It is sent out afterwards if it is not, then first being listened after preset time x2, if listening to channel idle, enters the instruction
The launch time window of information.
By above to the description of technical solution it can be seen that judging whether user equipment has the ability in the present embodiment
The measurement that DRS is completed in preset time y, thus before the measurement for not yet actually accomplishing DRS, it will be able to which whether predict in advance needs
It is first listened and is sent out afterwards.
S205, into the launch time window of instruction information.
Wherein, the instruction information is used to indicate the selected downlink beam index of the user equipment to base station.
Specifically, the instruction information can be some lead code (Preamble), such as PRACH (physical accidental access letter
Road, Physical Random Access CHannel) Preamble, it is also possible to some reference signal (Reference
Signal) or some uplink reference signals is also possible to such as SRS (detection reference signal, Sounding Reference RS)
Information in some physical channel, such as PUCCH (Physical Uplink Control Channel, Physical Uplink Control
CHannel)。
