The signal that can be implemented within the exemplary wireless communication network 100 of embodiment of the disclosure is shown in FIG. 1 Figure.Cordless communication network 100 may include one or more network equipment 101.For example, in this example, the network equipment 101 Base station can be presented as, for example, gNB.It should be understood that the network equipment 101 can also be presented as other forms, such as NB, eNB, BTS, BS or BSS, repeater etc..The network equipment 101 is multiple communication equipments within its coverage area 111-1,111-2 (hereafter referred to collectively as communication equipment 111) provide wireless connection.It should be understood that the arrangement in figure is only shown Example, which also may include more or less communication equipment or the network equipment.

In cordless communication network for example shown in FIG. 1, under the transmission from the network equipment to communication equipment can be referred to as Line link (DL) transmission, and the transmission in opposite direction is referred to as uplink (UL) link transmission.

In the cordless communication network 100 of Fig. 1, the network equipment 101 can use single wave beam or multiple wave beams execute DL transmission.For example, the communication equipment of different location in cell can be reached in order to guarantee and be initially accessed related broadcast message, Multiple transmission beam 110-140 can be used in the network equipment 101, such as using beam scanning technology, to transmit the broadcast message.

In general, signaling relevant to cell searching is (for example, primary synchronization signal (PSS), auxiliary synchronous letter in authorization carrier wave Number (SSS), system information (including such as Master Information Block (MIB) and auxiliary block of information (SIB)) are from base station (being known as gNB in NR) week Transmit to phase.

However, cordless communication network 100 as shown in Figure 1 may be needed support and be operated in unlicensed spectrum.If The traditional periodic transfer strategy directly reused in authorization frequency spectrum in unlicensed spectrum transmits initial access relevant information, then by In insecure channel access, which may not be delivered according to predefined timing.In addition, in unlicensed spectrum In, it needs to obtain resource based on competition, if base station can not access channel (that is, passing through in the subframe comprising system information Competition successfully obtains channel resource), then UE must not be not to wait for next period to receive corresponding system information.Therefore, unreliable Channel access may postpone the initial access of UE.

In order to increase the transmission success probability for being initially accessed relevant system information, the access (LAA) of LTE- authorization auxiliary System introduces version 12 (Rel-12) discovery reference signal (DRS) transmission of enhancing, to allow PSS/SSS and PBCH micro- 25 In the certain window of configuration under the channel sensing constraint of second (us), such as it is expressed as discovery signal measurement timing configured (DMTC), It is transmitted at interior different time position.According to the definition of the technical specification TS36.211V14.0.0 of 3GPP, the discovery signal of cell Transmission opportunity by 12 Orthodoxy Frequency Division Multiplex (OFDM) symbols in the non-empty frame of subframe structure type 3 it is lasting when Between form.It is operated by means of the high priority listem-before-talk (LBT) of the single sky channel detection (CCA) with 25us and flexible Transmission timing, LAA improve the probability that DRS is transmitted in each DMTC.Therefore, cell identification, Time and Frequency Synchronization and RRM measurement Performance be enhanced in unlicensed spectrum.

In addition, proposing the concept of the discovery signal (eDRS) of enhancing in MulteFire forum, additional is initially connect Enter relevant information (SIB1 and SIB2) merging LAA DRS.The eDRS transmission of MulteFire is further increased to be carried in unauthorized Single cell searching and the successful probability of system information transmissions in wave.According to the technical specification MFA of MulteFire Definition in 36.211v1.0.0, the transmission opportunity of the discovery signal of cell is by 14 in the non-empty frame of subframe structure type 3 The duration of a OFDM symbol forms.Fig. 2 is the schematic diagram of eDRS transmission.As shown in Fig. 2, eNB can be in DRS transmission window (DTxW) eDRS is transmitted in any single subframe (such as subframe 220) in 210.Wherein, DTxW 210 is that cell is specific, tool There are the duration of 1ms to 10ms and the minimum period of 40ms.It, can also be in the subframe in radio frame except DTxW 210 In 0, such as in one of subframe 240-270, the chance DRS information of scheduling portion, such as PSS, SSS, MIB or SIB.Pass through this Kind mode, being initially accessed relevant system information has more chances to be transmitted in unauthorized carrier wave.

Although eDRS is to have for the probability for increasing the delivering of single cell searching and system information in unauthorized carrier wave Benefit, this solution can not be directly reused in NR using the scene of multi-beam operation.

Using multi-beam, in order to realize that MPS process, gNB can be held in the transmission of discovery signal (DRS) Via multiple copies of multiple transmission beams transmission DRS during the continuous time.However, which means that with simple beam transmission compared with, it is whole The body transmitting continuous time will proportionally increase.For example, if in beam scanning each beam direction transmission time-consuming 1ms, Then gNB will need 8ms to transmit in 8 beam directions in the case where single port.Since the use of unlicensed spectrum limits, this length The transmission of time may meet with following problems.

Firstly, longest Channel holding time (MCOT) would generally be defined in unlicensed spectrum, such as not same district in the world About specified in the regulation of unlicensed spectrum in domain.The maximum duration that MCOT can transmit limitation discovery signal, and It will lead to discontinuous transmission.If it find that the transmission of signal is more than MCOT, then gNB should stop current burst, and again LBT operation is executed with the remainder for information, i.e. transmission of the DRS to remaining direction.Two DRS caused by being operated by LBT Transmission burst between gap be it is uncertain, therefore, UE should always wake up and to information carry out blind decoding.This will increase Handle the power consumption of complexity and UE.

Secondly, in the case where being configured with transmission window (DMTC or DTxW) in unlicensed spectrum, when based on multi-beam Discovery signal transmission be more than configuration transmission window when will have to stop.This causes the transmission of DRS to be interrupted.This In the case of, the UE of some regions or direction in cell will be unable to receive the information from gNB, so that it is initially accessed It is delayed by.

In addition, long duration may cause low channel access ability.According to the regulation in unlicensed spectrum, MCOT by The influence of the type and priority of LBT.Specifically, should be accounted in the less time by the transmission that higher LBT priority is initiated With channel, with the fairness for keeping resource to use, so that the UE with different service types of access network is averagely occupied equally In-flight time.Therefore, if it find that the transmitting continuous time of signal is too long, then corresponding LBT priority will be very low.And by Low channel access ability caused by this can destroy the original design intention of independent discovery signal.

In order to support the search of initial zone based on multi-beam, it is prominent that NR has had been incorporated into synchronization signal (SS) block (SSB), SS The structure of hair and SS burst set is transmitted for DL initial signal.It specifically may refer to the 3GPP's that in January, 2017 holds The chairman of RAN1NR ad hoc meeting (ad-hoc meeting) takes down notes (Chairman's Notes).When SSB is defined as one Between unit, the unit carry be directed to a wave beam NR-PSS, NR-SSS, NR-PBCH.SS burst for nominal SSB by transmitting One or more continuous resource constitute.SS burst set has the fixed period, is made of one or more SS burst. There are a wave beam duty cycles in a SS burst set.

In 3GPP RAN1 meeting, the composition of the SS burst set of different digital method (numerology) is reached At consensus, it specifically may refer to chairman's notes of the RAN1NR ad hoc meeting in June, 2017.Fig. 3 shows candidate SSB The example of one of mapping pattern.Assume in the example using three subcarrier spacings for being respectively 15kHz, 30kHz, 60kHz (SCS) SCS of the 30kHz in.In the exemplary construction of Fig. 3,4 SSB position candidate 310-340 are shown, respectively at 14 The 4-7 symbol of the first time slot in OFDM symbol, the 8-11 symbol of the first time slot, the 2-5 symbol of the second time slot and At the 6-9 symbol of two time slots.Other symbols in Fig. 3 are preserved for DL/UL control, protective time slot (GP) and DL/UL number According to.It may refer to 3GPP manuscript R1-1711899 about exemplary other details.

However, there are still some problems for this SS burst structure.Firstly, not including remaining minimum system information in SSB (RMSI), which is to be initially accessed relevant information.That is, the information in the SS burst structure is insufficient to allow terminal to set It is standby to execute initial access.How problem that RMSI be still open is transmitted.Secondly, the SS burst set structure in authorization frequency spectrum In, there are the symbols of some reservations for GP and/or DL/UL control or data between SSB.If do not had data to and SS Burst set is multiplexed together and reference signal is not configured, then will generate gap between transmission bursts.It this gap may To the chance of competition node manufacture access channel.

Therefore, it is necessary to provide more efficient and more reliable information transmission mode for unlicensed spectrum, for being based on The search of initial zone of multi-beam makes it possible to scan such as synchronization signal and system information within the relatively short duration.

In order to solve the problems, such as at least some of problems described above, proposes in the disclosure and sent and received for signal New signal structure.The structure can be used for sending and receiving, such as, but not limited to, the discovery signal in unauthorized NR, with side It helps and cell ID and system information is provided in unlicensed spectrum, convenient for the initial access based on multi-beam.It is used to not award In the case where weighing the discovery signal in NR, this new signal structure can be represented as U-NR-DRS.

The exemplary construction 400 of U-NR-DRS is shown in FIG. 4.As shown in figure 4, U-NR-DRS400 may include one Or SSB (hereinafter referred to as eSSB) 401-404 of multiple enhancings, and can extraly include that optional eSSB is supplemented (hereinafter It is expressed as eSSB-S) 411-414 and/or one or more stet, for such as DL control (Dc) 405, UL control Make (Uc) 406 or GP 407.

Although showing U-NR-DRS 400 in Fig. 4 includes that 4 eSSB 401-404, each eSSB correspond to a wave beam side To (one of the 110-140 of example as shown in figure 1), however this is only the purpose for example and signal, actually U-NR-DRS 400 In may include less or more eSSB.The U-NR-DRS structure makes it possible to cascade in short duration multiple continuous ESSB or multiple continuous eSSB and eSSB-S.Each eSSB (and eSSB-S) may include related with initial access Information and be associated with from different wave beam, so that gNB can be transmitted to multiple beam directions and is initially accessed related information. In some embodiments, the number of transmission beam used in the U-NR-DRS 400 is configurable.

GNB can execute the transmission beam scanning of a wheel, two-wheeled or more wheels in U-NR-DRS 400, to cover There is desired beam direction.In some embodiments, the first round beam scanning executed in U-NR-DRS is used for eSSB's Transmission, and the second wheel beam scanning can according to need execution, the transmission for such as eSSB-S.

In some embodiments, the eSSB that the disclosure proposes can be considered as the extension of traditional SSB.ESSB can regard one as Time quantum, wherein carrying NR-PSS, NR-SSS, the NR-PBCH for corresponding to wave beam and related attached with being initially accessed Adding system information, such as the related information of RMSI and possible other information.As an example, not a limit, related with RMSI Information may include RMSI message control information (for example, scheduling information or down link control information (DCI)) and/or RMSI message itself.

The optional other information that can include in the eSSB may include, such as, but not limited to: paging message, paging The control information (such as DCI) of message, the system information and its DCI unrelated with initial access, other broadcast signalings and with reference to letter One or more in number equal.

In some embodiments, the duration of time quantum eSSB can be constant or predetermined.As Example rather than limit, the duration of eSSB can be identical with existing SSB, to reduce change to standard, and obtains backward Compatible benefit.However in further embodiments, the duration of eSSB can be moved according to the payload size wherein carried State variation, more fully to utilize resource.

Optionally, the eSSB-S for including in U-NR-DRS 400, which can be carried, corresponding with a wave beam not to be held in eSSB The broadcast message of transmission is completed during the continuous time.In some system configurations, such as in the son with 20MHz bandwidth and 60kHz In the configuration at carrier wave interval, the not used frequency resource in traditional SSB duration is very limited.Therefore, if ESSB uses duration identical with SSB (such as 4 symbols), then is not made by NR-PSS, NR-SSS, NR-PBCH in eSSB Time/frequency resource is only enough to carry the additional DCI for RMSI and other system informations.In this case, RMSI and Other system informations can be transmitted in eSSB-S (such as eSSB-S 411-414 in Fig. 4).And the configuration of eSSB-S, example Such as whether in the presence of, duration, resource impact, scheduling information etc., can in eSSB (such as DCI by RMSI message) quilt Instruction.

Another advantage of the U-NR-DRS 400 proposed in the disclosure is flexibility.With showing in LAA and MulteFire Have DRS design different, the duration of U-NR-DRS can not be it is fixed, but depend on eSSB wherein included (and ESSB-S number), that is, the number depending on transmission beam.For example, gNB can only transmit several wave beams as needed ESSB and eSSB-S, rather than all wave beams are scanned.By means of the flexible U-NR-DRS duration, gNB can LBT operation of the adjustment for U-NR-DRS and U-NR-DRS transmission burst under different scenes and channel condition.

It should be noted that the U-NR-DRS that the disclosure proposes is not limited to specific structure shown in Fig. 4.Such as U-NR-DRS In can transmit unshowned other information and symbol, and/or, putting in order for eSSB, eSSB-S wherein included can With difference.

One embodiment according to the disclosure is shown in Fig. 5 in communication network (communication network 100 of example as shown in figure 1) Send the method 500 of signal.This method 500 can for example be implemented by the network equipment 101 in Fig. 1.However the disclosure is not It is limited to this.For the ease of discussing, method is described below with reference to network environment 100 described in the network equipment 101 and Fig. 1 500。

As shown in figure 5, in block 510, during the continual signal transmitting continuous time (such as U-NR- shown in Fig. 4 During the duration of DRS 400), the network equipment 101 is respectively via multiple transmission beams (the wave beam 110- of example as shown in figure 1 140) signal is sent.The signal can be such as (but not limited to) discovery signal.

As an example, the signal can be the signal in eSSB shown in Fig. 4.In some embodiments, which includes Synchronization signal (such as PSS, SSS, be referred to as SS), by PBCH transmission MIB signal and with to the initial of the communication network Access relevant additional system information.The additional system information can include but is not limited in RMSI message and its scheduling information At least one of.

Optionally, which can also further include at least one of the following: paging message, the scheduling of paging message Information, the system information unrelated with initial access, the scheduling information of the system information unrelated with initial access, except system information Broadcast signaling and reference signal.

In some embodiments, the duration (such as one of time quantum eSSB 401-404 in Fig. 4) of the signal Length can be it is constant or predetermined.For example, the duration of eSSB can be with the design of SSB in authorization frequency spectrum It is identical.For example, depending on the payload size of PBCH, the duration of eSSB can be fixed as 4-6 symbol.In other implementations In example, duration of signal can with the variation of content wherein included dynamic change.

That is, in some embodiments, in block 510, the network equipment 101 is in the continual signal transmitting continuous time It, can be respectively via multiple transmission beams with predefined length in (such as duration of the U-NR-DRS 400 of Fig. 4) Time quantum eSSB in send the signal.And in further embodiments, the network equipment 101 is held in the transmission of continual signal In continuous time U-NR-DRS, can send in the time quantum eSSB with variable-length via multiple transmission beams respectively should Signal.

Alternatively, or additionally, the length of the transmitting continuous time U-NR-DRS of signal can not be fixed.For example, such as Fruit system works in simple beam mode, then U-NR-DRS can be only comprising an eSSB and optional corresponding eSSB-S.If being System works in multi-beam mode, and in some embodiments, during the U-NR-DRS duration, gNB can be with time-multiplexed Mode sends the signal via multiple transmission beam respectively.That is, U-NR-DRS may include the company for multiple beam directions Continuous multiple eSSB.Correspondingly, the length of U-NR-DRS can be related to the number of the transmission beam in multiple transmission beam Connection, i.e., it is associated with the number of eSSB in U-NR-DRS.Further, the number (phase for the wave beam that gNB is transmitted in U-NR-DRS When in the number of eSSB) it can be dynamic configuration.For example, the number of eSSB can depend on gNB in order to full in U-NR-DRS Foot covering requires the wave beam number for needing to scan.In another embodiment, the number of the wave beam transmitted in U-NR-DRS can To be semi-statically to be configured by high-level signaling.

In addition, can be incited somebody to action when determining signal transmitting continuous time (such as duration of the U-NR-DRS 400 of Fig. 4) LBT operation for the signal transmitting continuous time accounts for.According to the regulation that LAA DRS LBT is operated, eNB can sensed Duration to channel idle up to the sensing interval of at least 25us and transmission transmits independent DRS after being less than 1ms immediately. It is directed to the regulation of 5GHz unauthorized frequency range according to ETSI, if the transmitting continuous time is less than 2ms, there is highest priority type LBT classification 4 can be performed.Therefore, in 5GHz unauthorized frequency range, the length of signal transmitting continuous time can be configured To be accessed and higher channel access probability with pursuing Fast Channel less than 2ms.

By being configured flexibly U-NR-DRS time duration, gNB can be adjusted in different scenes is used for U-NR- The LBT operation of DRS and U-NR-DRS transmission.
