Technical field

Embodiment described herein relates in general to wireless network and communication system.Some embodiments are related to cellular communications network Network, including 3GPP (third generation partner program) network, 3GPP LTE (long term evolution) network, 3GPP LTE-A (LTE high Grade) network, MulteFire^TM(MF) network and 5G networks, but the range of embodiment is without being limited thereto.Some embodiments are related to drilling Into type node B (eNB), which identifies based on how UE generates demodulated reference signal (DMRS) by unauthorized (unlicensed) user equipment (UE) of the frequency spectrum to eNB transmission datas.Other embodiment is related to UE and generates DMRS with indicated number Origin according to transmission and presence.

Background technology

The explosive growth of wireless traffic (traffic) leads to that there is an urgent need to improve rate.Utilize ripe physical layer skill Art, further increasing for spectrum efficiency will be inappreciable.On the other hand, the rare so that frequency spectrum of frequency spectrum is authorized in low-frequency band It is expanded into problem.Therefore, there are new interest for the operation of LTE system in an unlicensed spectrum.Technology is marked as a kind of Be denoted as enhanced mandate auxiliary access (eLAA), by using flexible carrier wave polymerization (CA) frame by the advanced introducings of LTE Lai Expansion system bandwidth, wherein principal component carrier wave (being referred to as main plot or PCell) operate and one or more in authorizing frequency spectrum A auxiliary component carrier (being referred to as secondary cell or SCell) operates in an unlicensed spectrum.Another method is in an unlicensed spectrum Independent LTE system, wherein the technology based on LTE only operate in an unlicensed spectrum without authorize frequency spectrum in " anchor ". This is MF systems.

In order to operate in an unlicensed spectrum, MF and eLAA systems need the letter for being different from traditional (legacy) LTE system Number structure and signaling technology.For example, the non-exclusive property of unlicensed spectrum needs such mechanism：ELAA/MF systems and other System (including the system operated together with other technologies (for example, Wi-Fi)) liberally shares wireless medium.ELAA/MF includes It LBT processes, wherein radio transmitter sensed media first and is only just sent when sensing medium clear.

LBT processes may lead to performance issue.For example, in eLAA and MF systems, uplink (UL) throughput performance It may be substantially reduced.Lead to one of this degradation the reason is that the efficiency due to operations scheduling system in an unlicensed spectrum is low Under.UL allowed transports need to complete multiple LBT processes.For example, LBT processes are happened at evolution NodeB (eNB) on component carrier Place, the expected physical down link control that there is scheduling physical uplink shared channel (PUSCH) and transmit on the component carrier Channel (PDCCH) processed or physical uplink control channel (PUCCH) are (for example, the enhanced PUCCH in MF systems (ePUCCH)).In the UL licenses carried in receiving PDCCH, scheduled UE also executes LBT before being transmitted.In addition, UL The delay of at least four subframes between being transmitted with corresponding PUSCH/PUCCH is permitted also to be attributable to UL performance issues.

A kind of mode for reducing these performance issues is to allow UE transmission datas on PUSCH, and UL is received without UE License.This disclosure relates to such process：For UE with it is non-scheduled, without Licensing Model transmission data when allow UE identify its from Body and the presence without allowed transport to eNB.UE can generate demodulated reference signal (DMRS) in this way：Once ENB detects that DMRS, eNB can identify the UE for sending DMRS and corresponding data symbols.

Specific implementation mode

In long term evolution (LTE) system, mobile terminal (being referred to as user equipment or UE) (is referred to as evolution via base station Type node B or eNB) it is connected to cellular network.LTE system usually will authorize frequency spectrum for the uplink between UE and eNB (UL) it is transmitted with downlink (DL).Fig. 1 shows the example of UE 120 and base station or the component of eNB 100.ENB 100 includes Processing circuit 101 is connected to the wireless set 102 for providing air interface.UE 120 includes processing circuit 121, It is connected to the wireless set 122 for providing air interface by wireless medium.Each transceiver in a device connects It is connected to antenna 150.

In various embodiments, UE 120 can be using unlicensed spectrum come to 100 transmission datas of eNB.For example, UE 120 can transmit data to eNB 100 using MF systems by PUSCH.In this mode, UE 120 is on PUSCH The UL licenses from eNB 100 are not asked or received before transmission data.When being permitted using UL, UL licenses provide UE 20 and use In to 100 transmission datas of eNB time and resource.Time and resource specified in being permitted based on UL eNB 100 knows UE 120 send what to eNB 100.When UE 120 in the case where no UL permits with it is non-scheduled, without Licensing Model carry out When transmission, eNB 100 does not know UE 120 just in transmission data.Therefore, eNB 100 needs a kind of method occurring to identify Data transmission and just in the UE of transmission data 120.In addition, eNB 100 need it is a kind of for determining when UL bursts start Method.In various embodiments, DMRS is generated by the UE 120 sent in a manner of identifying UE 120.Detecting DMRS When, eNB 100 can identify UE 120 and may infer that UL bursts have begun.ENB can also identify UE using DMRS It is used for the number of the carrier wave of UL burst transfers.DMRS (wherein each DMRS marks are detected over a number of carriers in eNB successes Same UE) after, eNB can determine the number of UE carrier waves currently in use.

Fig. 2 shows it is in accordance with some embodiments mark UE in unlicensed spectrum it is non-scheduled, without license UE transmission Example sequence diagram 200.By using downlink signaling, eNB 202 provides UE to UE 204 and identifies (identity) 210. In some embodiments, UE marks uniquely identify each UE communicated with eNB 202.ENB 202 can keep UE to mark Know and the mapping between corresponding UE.For example, eNB 202 can accord with UE identity maps to one other identification, which is being UE is uniquely identified in system or between two or more eNB.ENB 202 can use radio network temporary identifier (RNTI) (such as cell RNTI (C-RNTI)) is identified as UE.In other embodiments, UE marks can be set by UE rather than eNB It sets.For example, UE marks can be the mark for being assigned to SIM card used in UE.

In some embodiments, the mapping that DMRS sequences are identified to UE is unique so that DMRS is uniquely identified individually UE.In other embodiments, DMRS may map to two or more UE.Multiple UE, which are mapped to single DMRS, to be reduced The collision probability between the UE without license UL transmission is sent in same resource simultaneously.In these embodiments, eNB, which can be used, comes UE is determined from the information of the control information of the part as data transmission.For example, control information may include UE marks.

When UE 204 wants with without license, non-scheduled pattern to 202 transmission datas of eNB, then eNB 202 will not be carried Before know the transmission.Therefore, eNB 202 needs to detect the UE that the presence of transmission and identification are sent.With constant amplitude zero Any sequence of autocorrelation performance can be used for identifying the presence of transmission, reduce amount of collisions UE and can provide identifying about UE Information.For example, DMRS uses Zadoff-Chu (ZC) sequence.Therefore, DMRS can be used for detecting depositing for PUSCH data transmissions , for estimate channel and provide transmission data UE identification information.

In various embodiments, UE 204 can be by next life in a manner of some information for indicating or providing the mark about UE At DMRS.In the presence of can using three of DMRS for the use of.Root index determines the basic sequence of DMRS.Cyclic shift (CS) is used for Keep DMRS orthogonal in a frequency domain.Can orthogonal covering codes (OCC) be applied in the time and/or frequency domain so that DMRS signals and other DMRS is orthogonal.When eNB 202 detects DMRS, eNB 202 determines root index, CS and OCC for generating DMRS.However, Generation/detection DMRS does not need all these three aspects.It is indexed or using root index and CS next life for example, root can be used only At DMRS.In addition, identification PUSCH transmission and/or UE marks do not need all these three aspects.For example, only root index can be used for It identifies the presence of transmission and the information identified about UE is provided.In other embodiments, CS and OCC may together for generating DMRS And identify the mark of the presence of PUSCH transmission and the UE sent.

Before the transmission data in unlicensed spectrum, LBT processes that UE runs succeeded on one or more carrier waves 214.Once the one or more carrier waves of LBT processes instruction are available, UE 204 is just by data in (one or more) available carrier wave It is sent to eNB 202 with 216 the two of one or more DMRS.Because eNB 202 does not know UE just in transmission data, eNB It can blindly detect and whether there is any no allowed transport in available resources.For example, eNB can will be used for without license, it is non- It dispatches the signal received in any resource of UE transmission and is used to detect without one group of DMRS sequence existing for allowed transport It is related.When eNB 202 detects specific DMRS sequences, eNB 202 determines that UE is used for generating the parameter of DMRS, for example, root rope Draw, CS and OCC.By using one or more of root index, CS and OCC, eNB 202 can determine no allowed transport In the presence of and about send DMRS UE UE mark some information.In some embodiments, the information mark about UE marks Know the UE sent.If using one-to-one mapping, eNB 202 can determine UE itself 218.It is reflected if there is one-to-many It penetrates, then eNB can select one group of UE of shared received DMRS sequences.It can be decoded from the data portion of no allowed transport Go out UE to identify and match with a UE in this group of UE.

The selection to root index, CS and OCC can be completed in various ways.In some embodiments, eNB can be via Radio resource control (RRC) signaling or other high-level signalings to send root index, CS, and/or OCC with signal.In other realities It applies in example, the selection to root index, CS and OCC can be the function of UE marks.It is, for example, possible to use modular arithmetic selects root Index.For example, mod (UE is identified, N), wherein N are the numbers that can be used for the available root index without license, non-scheduled transmission.It can be with Complete the selection to CS and OCC in a similar way.CS can be selected as mod (UE is identified, N), and wherein N is available CS Number (for example, 12).OCC can be selected as to mod (UE is identified, N), wherein N is the number of available OCC.In some embodiments In, UE marks are radio network temporary identifier (RNTI) (for example, cell RNTI (C-RNTT)).

The number for the available root index without license, non-scheduled transmission can be determined with integrated with traditional LTE system.It is right In root index selection, the length for the DMRS ZC sequences generated is less than the number of the resource element (RE) for no allowed transport Purpose largest prime, is indicated by M, for example, if one interweaves and is used for no allowed transport, M=113, and if ten A intertexture is used for no allowed transport, then M=1193, this so that 113 possible ZC sequences can be used in total.When DMRS's When length is more than the length M of ZC sequences, by the end that (length of DMRS-M) element of foremost is copied to ZC sequences By the length of ZC sequence extensions to DMRS.For example, when DMRS length is 120, it includes 113 ZC sequences, element 0-6 quilts It is added to the end of ZC sequences.The number of the root index used in the traditional LTE system for being defined for generating UL DMRS is 60, M-60 unused but available ZC sequences are left, can be used for generating M-60 root index.In some embodiments, M etc. In 113, lead to the 53 roots index that can be used for no allowed transport.It in some embodiments, can be by defined 60 root ropes Some or all of draw and to distribute to scheduled UE.Such as those defined above function can be used for root index being mapped to spy Determine UE.Remaining and not used 53 roots index can be used for it is non-scheduled, without license UE.Such as those defined above function It can be used for root index being mapped to particular UE.Different functions can be used for two groups of root indexes.In other embodiments, it defines Two groups of independent indexes, one of which are transmitted by scheduled UL and are used, another group by it is non-scheduled, make without license UL transmission With.In these embodiments, a part of of 60 DMRS sequences can be assigned to scheduled UL transmission, and 60 DMRS sequences Another part of row can be assigned to no allowed transport.

In some embodiments, eNB can provide the group to UE via downlink signaling and can be indexed with root.Then, UE It can be identified based on its UE to select to be used index.In these embodiments, eNB is known that UE marks and UE are used for The function for selecting root index, to allow eNB that root index is mapped to UE marks.In other embodiments, UE can receive work For system information a part or received from eNB but be indicated as the available root used across multiple eNB or whole system Index.However, in other embodiments, eNB provides particular UE and should be indexed via the root that downlink signaling uses.It can be with class As mode provide/determine other aspects of DMRS, such as CS and OCC.

Once generating DMRS as described above, DMRS is just sent to eNB by UE.As described above, DMRS allows eNB to identify UL The presence of transmission simultaneously determines just in the mark of the UE of transmission data.Fig. 3 shows in accordance with some embodiments for uplink The pilotaxitic texture of transmission.First Figure 30 2 shows various intertextures, and wherein y-axis can indicate that resource block (RB) indexes, and x-axis It can indicate symbol.In some embodiments, each intertexture includes ten Physical Resource Block (PRB).It is each interweave in figure 3 by It is shown as that there is the row of different shades to distinguish different intertextures.In some embodiments, system bandwidth can be 20MHz, always Share 100 PRB and ten intertextures.The distance between PRB in same intertexture is 10 multiple.For example, interweaving 0 with PRB 0, PRB 10, PRB 20, until PRB 90.Interweave 1 have PRB 1, PRB 11, PRB 21, until PRB 91.In other embodiment In, system bandwidth can be 10MHz.In these embodiments, 50 PRB and 5 intertextures, each intertexture can still have 10 A PRB.

Each RB can have 12 subcarriers, be shown in second Figure 30 4.Symbol can shown in Figure 30 2 and 304 To be the symbol transmitted on PUSCH.The transmission of resource block other resource block interleavings with shown in are similar in MF systems PUSCH and short physical uplink control channel (sPUCCH) transmission.Multiple intertextures can be distributed to different UE or same One UE.

In some embodiments, DMRS can be sent at the center mark of the time slot in UL transmission.It is similarly to passing In LTE system of uniting in PUSCH transmission the case where transmission DMRS.For example, two time slots 310 and 312 can be defined.Each show Time slot include seven symbols.It can be sent using DMRS as the center mark of each time slot, time slot 310 as shown The symbol 322 of symbol 320 and time slot 312.Other symbols 330 can be used for from UE transmission datas.

DMRS can also be sent at the beginning that UL happens suddenly.This allows DMRS to be used as being indicated to eNB from specific The initial signal that the UL bursts of UE are starting.Because eNB does not know without when license, non-scheduled UE transmission reach and definitely Will reach where, so the DMRS successfully being detected can indicate to follow the UL of the DMRS to happen suddenly.

As the part for using unlicensed spectrum, UE completes LBT processes before transmitting data.In addition, being awarded due to non- The property of frequency spectrum is weighed, various equipment can at any time be sent in same unlicensed spectrum.UE can it is in office when Between complete LBT processes, but may can not start transmission data due to subframe or the boundary of time slot alignment requirements of PUSCH transmission. For example, LBT processes can be completed in the intermediate of subframe, time slot, and/or symbol so that UE needs to wait for before transmitting data Next subframe, time slot and/or character boundary.However, if the UE does not start to send some data, another equipment can be with It completes its LBT process and proceeds by transmission, to capture channel and prevent the transmission of the UE.In some embodiments, in LBT After process, UE can repeatedly send DMRS to retain frequency spectrum.In these embodiments, eNB can use the leading DMRS Come determine UE will start quickly it is non-scheduled, without license data transmit.In some embodiments, success LBT terminate after and Before the subsequent time slot or sub-frame boundary that PUSCH transmission can start, DMRS is sent at the beginning of UL transmission.Still may be used To send DMRS at the center mark in each time slot of PUSCH transmission.In some embodiments, start in PUSCH transmission The DMRS sequences sent before and the DMRS sequences sent in PUSCH subframes can be different.

When DMRS the beginning that UL happens suddenly or as preserved signal by use, eNB can than only PASCH transmission DMRS is sent in the center mark of each time slot detects that UL is transmitted earlier.In addition, sent at the beginning of UL bursts DMRS can indicate the beginning that UL happens suddenly to eNB.This allows UE to start UL bursts, wherein UL bursts in part subframe or time slot It is not aligned with subframe or boundary of time slot.DMRS can also provide automatic growth control (AGC) setting for each UL burst transfers.
