具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
本发明各实施例适用于在非授权频谱进行直连通信，以LTE系统和wifi系统在非授权频谱共存为例进行说明，也适用于有其它更多系统共存的场景。在蜂窝系统中本发明以LTE系统为例，所揭示的方法自然也适用于通用移动通信系统(Universal MobileTelecommunications System，简称：UMTS)、全球移动通信系统(Global System forMobile communication，简称：GSM)、码分多址(Code Division Multiple Access，简称：CDMA)2000等其它蜂窝系统。LTE基站根据发射功率和下行(downlink)覆盖范围的不同一般可以分为微基站(Pico eNB)、小基站(Micro或small eNB)或宏基站(macro eNB)，其中，小基站和微基站更适合使用非授权频谱，因为其发射功率小，对异系统的干扰也比较容易进行灵活的控制；宏基站使用非授权频谱一般需要结合波束赋形(beamforming)技术，以免在较大的覆盖范围内造成广泛干扰。本发明实施例所涉及的LTE基站也适用于上述各种基站。Various embodiments of the present invention are applicable to direct communication in unlicensed spectrum, and the coexistence of LTE system and wifi system in unlicensed spectrum is used as an example for illustration, and are also applicable to scenarios where more systems coexist. In the cellular system, the present invention takes the LTE system as an example, and the disclosed method is naturally also applicable to Universal Mobile Telecommunications System (UMTS for short), Global System for Mobile communication (GSM for short), code Code Division Multiple Access (CDMA for short) 2000 and other cellular systems. LTE base stations can generally be divided into pico base stations (Pico eNB), small base stations (Micro or small eNB) or macro base stations (macro eNB) according to different transmission power and downlink (downlink) coverage. Among them, small base stations and micro base stations are more suitable The use of unlicensed spectrum, because of its low transmission power, is relatively easy to flexibly control the interference of different systems; the use of unlicensed spectrum by macro base stations generally needs to be combined with beamforming (beamforming) technology to avoid causing interference in a large coverage area. Widespread interference. The LTE base station involved in the embodiment of the present invention is also applicable to the above-mentioned various base stations.
LTE系统使用非授权频谱或作为次级用户使用其他系统的授权频谱时，在基站的覆盖区域可能存在异系统，例如无线保真(Wireless Fidelity，简称：wifi)系统或电视系统，使用同一频带的非授权频谱或电视白频谱(Television White Space，简称：TVWS)，在LTE系统和wifi系统的共同覆盖区域可能存在同频干扰，例如当LTE系统和wifi系统的覆盖有重叠且频率有重叠时，如果LTE系统和wifi系统在有重叠的频率范围同时在各自的系统进行通信，则可能导致同频干扰。LTE系统和wifi系统需要在系统间进行协作或者各系统的设备均通过检测和避让等方式共享非授权频谱，以使各系统都能够正常进行通信。LTE系统作为次级用户使用其他系统的授权频谱的情况，例如LTE系统使用TVWS时，电视系统作为主用户其优先级高于LTE系统作为次级用户的优先级，LTE系统仅当电视系统不占用TVWS时才能够使用TVWS，而且一旦LTE系统检测到电视系统开始使用TVWS，需要立即避让而进入静默期，或者降低发射功率至规定范围，从而不影响电视系统的正常工作。本发明的各实施例中，LTE基站和用户设备以载波聚合(Carrier Aggregation，简称：CA)技术进行通信，辅服务小区(Secondary Cell，简称：SCell)使用非授权频谱为例，也适用于SCell使用异系统的授权频谱的情况。When the LTE system uses the unlicensed spectrum or uses the licensed spectrum of other systems as a secondary user, there may be different systems in the coverage area of the base station, such as a wireless fidelity (Wireless Fidelity, referred to as: wifi) system or a TV system. Unlicensed spectrum or TV White Space (TVWS for short), there may be co-channel interference in the common coverage area of LTE system and wifi system, for example, when the coverage and frequency of LTE system and wifi system overlap, If the LTE system and the wifi system communicate in their respective systems at the same time in overlapping frequency ranges, it may cause co-channel interference. The LTE system and the wifi system need to cooperate between the systems or the devices of each system share the unlicensed spectrum through detection and avoidance, so that each system can communicate normally. When the LTE system uses the authorized spectrum of other systems as a secondary user, for example, when the LTE system uses TVWS, the priority of the TV system as the primary user is higher than that of the LTE system as the secondary user, and the LTE system is only used when the TV system does not occupy TVWS can only be used when TVWS is used, and once the LTE system detects that the TV system starts to use TVWS, it needs to avoid immediately and enter a silent period, or reduce the transmission power to the specified range, so as not to affect the normal operation of the TV system. In each embodiment of the present invention, the LTE base station and the user equipment communicate with the carrier aggregation (Carrier Aggregation, referred to as: CA) technology, and the secondary serving cell (Secondary Cell, referred to as: SCell) uses unlicensed spectrum as an example, which is also applicable to SCell The case of using licensed spectrum of different systems.
图1为本发明用户设备实施例一的结构示意图。本发明实施例提供了一种用户设备，适用于在非授权频谱上进行直连通信，可以应用于公共安全和商业等用途，工作模式有设备间对等通信、本地广播和用户设备中继通信等。该用户设备为第一用户设备，其中，本发明任一实施例中的“第一”和“第二”仅为区分直连通信中不同的设备或模块，例如，第一用户设备和第二用户设备是为区分进行直连通信中不同的用户设备。如图1所示，该用户设备10包括：第一接收器11、第一处理器12和第一发送器13。FIG. 1 is a schematic structural diagram of Embodiment 1 of a user equipment according to the present invention. The embodiment of the present invention provides a user equipment, which is suitable for direct communication on unlicensed spectrum, and can be used for public safety and business purposes. The working modes include inter-device peer-to-peer communication, local broadcast and user equipment relay communication. Wait. The user equipment is the first user equipment, wherein "first" and "second" in any embodiment of the present invention are only used to distinguish different devices or modules in direct communication, for example, the first user equipment and the second The user equipment is used to distinguish different user equipments performing direct communication. As shown in FIG. 1 , the user equipment 10 includes: a first receiver 11 , a first processor 12 and a first transmitter 13 .
其中，第一接收器11用于通过配置频谱接收第二用户设备发送的控制信号；第一处理器12与第一接收器11连接，用于根据控制信号，测量非授权频谱上直连通信的无线参数，并将测量结果生成测量报告；第一发送器13与第一处理器12连接，用于发送测量报告给基站，以使基站根据该测量报告为第一用户设备和第二用户设备分配用于数据通信的无线资源。Wherein, the first receiver 11 is used to receive the control signal sent by the second user equipment by configuring the spectrum; the first processor 12 is connected to the first receiver 11, and is used to measure the direct communication on the unlicensed spectrum according to the control signal. wireless parameters, and generate a measurement report from the measurement results; the first transmitter 13 is connected to the first processor 12, and is used to send the measurement report to the base station, so that the base station assigns the first user equipment and the second user equipment according to the measurement report. Radio resources used for data communication.
具体地，配置频谱可以为LTE系统的授权频谱，也可以为非授权频谱。Specifically, the configured spectrum may be a licensed spectrum of the LTE system, or may be an unlicensed spectrum.
将非授权频谱应用于SCell时，LTE系统首先侦听频谱是否空闲，即“讲前先听(Listen Before Talk，简称：LBT)”，以避免对正在使用非授权频谱的其他用户的干扰。当非授权频谱未被异系统占用的情况下，可以由SCell获取作为额外的无线资源用于和用户设备通信。根据频谱法规，LTE系统获取到非授权频谱使用一段时间后需要暂时释放频谱资源以给予共存的异系统获取到非授权频谱的机会，或者LTE系统在非授权频段遭遇较强干扰在通信质量难以保证等情况也可以暂时释放频谱资源。LTE系统释放频谱资源后需要重新竞争到频谱资源才能继续使用非授权频谱进行通信。When applying the unlicensed spectrum to the SCell, the LTE system first monitors whether the spectrum is idle, that is, "Listen Before Talk (abbreviated: LBT)", so as to avoid interference to other users who are using the unlicensed spectrum. When the unlicensed spectrum is not occupied by a foreign system, it can be obtained by the SCell as an additional radio resource for communication with the user equipment. According to the spectrum regulations, the LTE system needs to temporarily release the spectrum resources after obtaining the unlicensed spectrum for a period of time to give the coexisting heterogeneous system the opportunity to obtain the unlicensed spectrum, or the LTE system encounters strong interference in the unlicensed frequency band and the communication quality is difficult to guarantee. Spectrum resources can also be temporarily released in other situations. After the LTE system releases spectrum resources, it needs to re-compete for spectrum resources to continue using unlicensed spectrum for communication.
其中，控制信号为直连通信中数据传输之前用户设备10间的信令交互，包括同步信号和发现信号，其中，同步信号可以至少包含D2D主同步信号(D2D primarysynchronization signal，简称：D2D PSS)，还可以包含D2D辅同步信号(D2D secondarysynchronization signal，简称：D2D SSS)，参考信号的序列设计可以参照LTE小区通信模式的主同步信号PSS、辅同步信号SSS；发现信号可以为解调参考信号(DemodulationReference Signal，简称：DMRS)、探测参考信号(Sounding Reference Signal，简称：SRS)或专用前导(dedicated preamble)等。无线资源可以由基站分配给直连通信的用户设备10，也可以通过主设备(master device)分配给直连通信的用户设备10；分配无线资源的方式包括动态信令分配和半静态配置。Wherein, the control signal is the signaling interaction between the user equipments 10 before data transmission in direct communication, including a synchronization signal and a discovery signal, wherein the synchronization signal may at least include a D2D primary synchronization signal (D2D primary synchronization signal, D2D PSS for short), It can also include a D2D secondary synchronization signal (D2D secondary synchronization signal, referred to as: D2D SSS). The sequence design of the reference signal can refer to the primary synchronization signal PSS and the secondary synchronization signal SSS of the LTE cell communication mode; the discovery signal can be a demodulation reference signal (DemodulationReference Signal, DMRS for short), sounding reference signal (Sounding Reference Signal, SRS for short), dedicated preamble (dedicated preamble), etc. The radio resource can be allocated to the user equipment 10 in direct communication by the base station, or can be allocated to the user equipment 10 in direct communication through a master device; the ways of allocating radio resources include dynamic signaling allocation and semi-static configuration.
由于现有技术不支持LTE系统中D2D直连通信工作在非授权频谱，本发明实施例将LTE系统应用于非授权频谱，以有效利用非授权频谱资源，提高LTE系统中用户的可用频谱带宽。Since the existing technology does not support the D2D direct communication in the LTE system to work in the unlicensed spectrum, the embodiment of the present invention applies the LTE system to the unlicensed spectrum to effectively use the unlicensed spectrum resources and increase the available spectrum bandwidth for users in the LTE system.
另外，当LTE系统中D2D直连通信工作在非授权频谱，且多个系统动态共享非授权频谱资源时，由于非授权频谱的获得在时间和频率上可能都是非连续的，有一定的间歇性，直连通信中用户设备对于非授权频谱的频谱感知或频谱检测也存在一定的误差和时延，导致有些情况下直连通信中用户设备的同步信号和/或发现信号可靠性降低而增加数据通信的错误和延迟，降低频谱资源利用率，因此，在本发明实施例中，进行直连通信的某一用户设备，即第一用户设备，通过基站预先配置的配置频谱接收该直连通信中其它用户设备，即第二用户设备，发送的控制信号，从而提高直连通信中控制信号，例如，同步信号和发现信号的可靠性，降低通信延迟。In addition, when the D2D direct communication in the LTE system works in the unlicensed spectrum and multiple systems dynamically share the unlicensed spectrum resources, since the acquisition of the unlicensed spectrum may be discontinuous in time and frequency, there is a certain intermittent , there are certain errors and delays in the spectrum sensing or spectrum detection of the user equipment for the unlicensed spectrum in the direct connection communication, which leads to the decrease of the reliability of the synchronization signal and/or discovery signal of the user equipment in the direct connection communication in some cases and increases the data Errors and delays in communication reduce the utilization rate of spectrum resources. Therefore, in the embodiment of the present invention, a certain user equipment performing direct communication, that is, the first user equipment, receives the information in the direct communication through the configured frequency spectrum pre-configured by the base station. The other user equipment, that is, the second user equipment, sends the control signal, so as to improve the reliability of the control signal in the direct communication, for example, the synchronization signal and the discovery signal, and reduce the communication delay.
当配置频谱为LTE系统的授权频谱时，该授权频谱被LTE系统独占或者LTE系统具有最高优先级，因此该配置频谱的可靠性高；当配置频谱为非授权频谱时，当非授权频谱的无线参数适宜时，第一用户设备在该配置频谱上接收控制信号，第二用户设备在该配置频谱发送控制信号，因此该配置频谱的可靠性高。基站根据非授权频谱的测量报告确定非授权频谱的无线参数适宜时指示第一用户设备在该配置频谱上接收控制信号，第二用户设备在该配置频谱发送控制信号；或者第一用户设备根据自己的测量结果，确定非授权频谱的无线参数适宜时在该配置频谱上接收控制信号，第二用户设备根据自己的测量结果确定非授权频谱的无线参数适宜时在该配置频谱上发送控制信号。When the configured spectrum is the licensed spectrum of the LTE system, the licensed spectrum is exclusively occupied by the LTE system or the LTE system has the highest priority, so the reliability of the configured spectrum is high; when the configured spectrum is the unlicensed spectrum, when the wireless When the parameters are appropriate, the first user equipment receives the control signal on the configured frequency spectrum, and the second user equipment sends the control signal on the configured frequency spectrum, so the reliability of the configured frequency spectrum is high. When the base station determines that the wireless parameters of the unlicensed spectrum are suitable according to the measurement report of the unlicensed spectrum, it instructs the first user equipment to receive the control signal on the configured spectrum, and the second user equipment sends the control signal on the configured spectrum; or the first user equipment according to its own When determining that the wireless parameters of the unlicensed spectrum are appropriate, the second user equipment receives the control signal on the configured spectrum, and the second user equipment determines that the wireless parameters of the unlicensed spectrum are appropriate according to its own measurement results. Send the control signal on the configured spectrum.
在上述实施例中，对于第二用户设备发送的控制信号，第一接收器11可以全部接收，也可以部分接收。可选地，若第一处理器12确定非授权频谱可用，则触发第一接收器11通过配置频谱接收第二用户设备发送的控制信号。其中，第一处理器12可以通过以下方式确定非授权频谱可用：In the foregoing embodiment, the first receiver 11 may receive all or part of the control signal sent by the second user equipment. Optionally, if the first processor 12 determines that the unlicensed spectrum is available, trigger the first receiver 11 to receive the control signal sent by the second user equipment by configuring the spectrum. Wherein, the first processor 12 may determine that the unlicensed spectrum is available in the following manner:
方式一：第一处理器12检测到第一接收器11接收到基站发送的指示信息，该指示信息用于指示非授权频谱可用；Mode 1: The first processor 12 detects that the first receiver 11 has received indication information sent by the base station, and the indication information is used to indicate that the unlicensed spectrum is available;
方式二：第一处理器12根据其自身对非授权频谱上直连通信的无线参数的测量结果，确定非授权频谱可用。Manner 2: The first processor 12 determines that the unlicensed spectrum is available according to its own measurement results of the wireless parameters of the direct communication on the unlicensed spectrum.
其中，确定非授权频谱可用时所依据的无线参数可以低于上述确定非授权频谱无线参数适宜时所依据的无线参数。Wherein, the wireless parameter used for determining that the unlicensed spectrum is available may be lower than the wireless parameter used for determining that the wireless parameter of the unlicensed spectrum is suitable.
非授权频谱可用至少包含两种情况：一种情况是非授权频谱处于空闲状态，未被其他无线接入系统占用；一种情况是尽管其他无线接入系统占用了非授权频段，但距离基站和/或用户设备较远或者功率较低等情况，基站与用户设备之间或用户设备之间仍然可以使用非授权频谱正常通信，且不对其他无线接入系统造成严重干扰。The availability of unlicensed spectrum includes at least two situations: one situation is that the unlicensed spectrum is idle and not occupied by other wireless access systems; the other situation is that although other wireless access systems occupy the unlicensed frequency band, the distance from the base station and/or Or when the user equipment is far away or the power is low, the base station and the user equipment or between the user equipment can still use the unlicensed spectrum for normal communication without causing serious interference to other wireless access systems.
通过以下两种方式，第一用户设备根据非授权频谱的可用状态发送和/或接收控制信号，从而节省了配置频谱上的无线资源，也降低了第一用户设备的电池消耗和功率损耗。In the following two ways, the first user equipment sends and/or receives control signals according to the available state of the unlicensed spectrum, thereby saving radio resources on the configured spectrum and reducing battery consumption and power consumption of the first user equipment.

在上述基础上，若第一用户设备30和第二用户设备40处于不同的基站下辖的小区，则第一处理器12还可用于：根据第一用户设备30与第二用户设备40间交互非授权频谱的占用信息，确定控制信号的接收时间，在接收时间触发第一接收器11通过授权频谱接收第二用户设备40发送的控制信号；或，根据第一接收器11从第一用户设备30所在基站获取非授权频谱可用的通知，确定控制信号的接收时间，在接收时间触发第一接收器11通过授权频谱接收第二用户设备40发送的控制信号，其中，该通知为第一用户设备30和第二用户设备40各自所在基站进行非授权频谱占用信息交互的结果，用于指示第一用户设备30和第二用户设备40进行直连通信。可选地，第二处理器22还可以用于：在第二接收器21接收用户设备10发送的测量报告之前，与进行直连通信的另一用户设备所处的另一基站进行非授权频谱占用信息的交互，并根据交互结果实现基站间同步，及通知用户设备10进行直连通信。On the basis of the above, if the first user equipment 30 and the second user equipment 40 are in different cells under the jurisdiction of the base station, the first processor 12 is further configured to: according to the interaction between the first user equipment 30 and the second user equipment 40 Occupancy information of the unlicensed spectrum, determine the receiving time of the control signal, and trigger the first receiver 11 to receive the control signal sent by the second user equipment 40 through the licensed spectrum at the receiving time; or, according to the first receiver 11 from the first user equipment The base station where 30 is located obtains a notification that the unlicensed spectrum is available, determines the receiving time of the control signal, and triggers the first receiver 11 to receive the control signal sent by the second user equipment 40 through the licensed spectrum at the receiving time, wherein the notification is the first user equipment The results of unlicensed spectrum occupancy information exchange between base stations where the 30 and the second user equipment 40 are located are used to instruct the first user equipment 30 and the second user equipment 40 to perform direct communication. Optionally, the second processor 22 may also be configured to: before the second receiver 21 receives the measurement report sent by the user equipment 10, perform an unlicensed spectrum operation with another base station where another user equipment performing direct communication is located. Occupy information interaction, realize synchronization between base stations according to the interaction result, and notify user equipment 10 to perform direct communication.
如图7所示，第一用户设备30位于第一基站50提供的小区，第二用户设备40位于第二基站60提供的小区，其中，第一基站50和第二基站60在位置上相邻；或者，如图8所示，第一用户设备30和第二用户设备40位于对其进行基站间载波聚合的两个小区，例如，第一用户设备30和第二用户设备40均已配置CA，CA由主基站(Master eNB，简称：MeNB)70和辅基站(Secondary eNB，简称：SeNB)80提供的小区进行聚合，其中MeNB 70提供的小区之一工作在非授权频谱，其中SeNB 80提供的小区之一工作在非授权频谱。两个基站提供的LTE系统的授权频谱上的小区和非授权频谱上的小区均需要同步，例如，在系统帧号(System FrameNumber，简称：SFN)和子帧(subframe)级别均达到同步，可以通过现有技术的基站间同步实现。As shown in FIG. 7, the first user equipment 30 is located in a cell provided by a first base station 50, and the second user equipment 40 is located in a cell provided by a second base station 60, wherein the first base station 50 and the second base station 60 are adjacent in position or, as shown in FIG. 8 , the first user equipment 30 and the second user equipment 40 are located in two cells on which inter-base station carrier aggregation is performed, for example, the first user equipment 30 and the second user equipment 40 have been configured with CA , the CA is aggregated by the cells provided by the master base station (Master eNB, referred to as: MeNB) 70 and the secondary base station (Secondary eNB, referred to as: SeNB) 80, wherein one of the cells provided by the MeNB 70 works in an unlicensed spectrum, and the SeNB 80 provides One of the cells operates in the unlicensed spectrum. Both the cells on the licensed spectrum and the cells on the unlicensed spectrum of the LTE system provided by the two base stations need to be synchronized. Synchronization between base stations in the prior art is realized.
其中，第一处理器12根据非授权频谱的占用信息，确定控制信号的接收时间的实施方式中，第一用户设备30与第二用户设备40间直接交互，需已确定两用户设备间可以进行直连通信，即两用户设备相互同步和发现之后。另外，也可以用户设备间直通过基站交互，例如均向基站上报非授权频谱的占用信息，然后由基站确定接收时间。Wherein, in the embodiment in which the first processor 12 determines the receiving time of the control signal according to the occupation information of the unlicensed spectrum, the first user equipment 30 and the second user equipment 40 interact directly, and it needs to be determined that the two user equipments can communicate with each other.

In addition, user equipments may interact directly through the base station, for example, they all report the occupation information of the unlicensed spectrum to the base station, and then the base station determines the receiving time.
还需说明的是，该实施例中，基站为用户设备配置CA和D2D的过程同上述实施例，但对于授权频谱上的同步信号和发现信号的无线资源分配，需两个基站通过基站间接口(例如X2接口)协商，在两个基站分别为其各自服务的用户设备所分配的无线资源需保持一致，从而用户设备间可以在相同的无线资源上进行控制信号的发送和接收。It should also be noted that in this embodiment, the base station configures CA and D2D for the user equipment. (for example, X2 interface) negotiation, the radio resources allocated by the two base stations to the user equipments served by them respectively need to be consistent, so that the user equipments can send and receive control signals on the same radio resources.
具体地，分别由两个基站服务的不同用户设备在获取到非授权频谱时，需两基站通过X2接口交互，或者通过用户设备之间的直接连接进行通知，或者通过两个基站和用户设备均可访问到的公共信道进行通知，只有在两基站下的非授权频谱上的小区被LTE系统占用的时间发生重叠时，可以进行用户设备之间的数据通信，而用户设备间的同步信号和发现信号才可以通过授权频谱进行发送。Specifically, when different user equipments served by two base stations respectively obtain unlicensed spectrum, the two base stations need to interact through the X2 interface, or notify through the direct connection between the user equipments, or pass the two base stations and the user equipment both The accessible public channel is notified, and only when the cells on the unlicensed spectrum under the two base stations are overlapped by the LTE system, the data communication between the user equipment can be carried out, and the synchronization signal between the user equipment and the discovery Signals can only be sent through the licensed spectrum.

另一种实现方式中，第一接收器11可以具体用于：通过非授权频谱接收第二用户设备发送的控制信号，该控制信号包括同步信号和发现信号。In another implementation manner, the first receiver 11 may be specifically configured to: receive a control signal sent by the second user equipment through an unlicensed spectrum, where the control signal includes a synchronization signal and a discovery signal.
结合图1、图3和图4对该实现方式进行说明。如图9和图10所示，其中，横轴为时间轴，纵轴表示频谱。非授权频谱中，虚线部分表示非授权频谱不可用，实线部分表示非授权频谱可用，第二用户设备40周期发送同步信号，即t31、t32、t33、t34和t35等时刻，而第一用户设备30仅在非授权频谱可用时才接收同步信号，例如t33和t35时刻。The implementation will be described with reference to FIG. 1 , FIG. 3 and FIG. 4 . As shown in FIG. 9 and FIG. 10 , the horizontal axis is the time axis, and the vertical axis represents the frequency spectrum. In the unlicensed spectrum, the dotted line indicates that the unlicensed spectrum is unavailable, and the solid line indicates that the unlicensed spectrum is available. The second user equipment 40 periodically sends synchronization signals, that is, at times t31 , t32 , t33 , t34 and t35 , and the first user equipment 30 receives the synchronization signal only when the unlicensed spectrum is available, such as time t33 and time t35 .

其中，第一用户设备30和第二用户设备40采用不同的时频域资源发送同步信号和/或发现信号，例如，在子帧和频率上区分开以避免冲突。基站20配置用户设备10仅在接收到基站20指示的非授权频谱可用信息时或用户设备10自己判断非授权频谱可用时才周期性发送和/或接收上述控制信号。Wherein, the first user equipment 30 and the second user equipment 40 use different time-frequency domain resources to send the synchronization signal and/or the discovery signal, for example, distinguish them in subframes and frequencies to avoid conflicts. The base station 20 configures the user equipment 10 to periodically send and/or receive the above control signal only when receiving the unlicensed spectrum available information indicated by the base station 20 or when the user equipment 10 judges that the unlicensed spectrum is available.
当非授权频谱包含多个频率时，第一处理器12根据非授权频谱的范围，选择其对应的可用频率范围进行控制信号的传输。具体地，在非授权频谱包含多个频率时，基站20可以为用户设备10在多个频率上配置上述控制信号的资源，以使得用户设备10根据非授权频谱上具体频率范围的可用情况选择相应的可用频率范围发送和/或接收上述控制信号；基站20也可以配置用户设备10在非授权频谱不可用时，以较低功率和/或不同的周期发送和/或接收上述信号。When the unlicensed spectrum includes multiple frequencies, the first processor 12 selects the corresponding available frequency range to transmit the control signal according to the range of the unlicensed spectrum. Specifically, when the unlicensed spectrum contains multiple frequencies, the base station 20 can configure the resource of the above-mentioned control signal on multiple frequencies for the user equipment 10, so that the user equipment 10 can select the corresponding The base station 20 may also configure the user equipment 10 to send and/or receive the above-mentioned signals with lower power and/or at different periods when the unlicensed spectrum is unavailable.
用户设备10根据同步信号和发现信号的配置信息，在非授权频谱上周期性发送/接收上述控制信号。The user equipment 10 periodically sends/receives the above control signal on the unlicensed spectrum according to the configuration information of the synchronization signal and the discovery signal.
具体地，基站20根据用户设备10上报的非授权频谱测量信息，判断非授权频谱可用，通过PCell上的PDCCH或EPDCCH指示用户设备10开始发送和/或接收上述信号，用户设备10接收到基站20指示后在非授权频谱上周期性发送和/或接收上述信号；或者，用户设备10根据其自身对非授权频谱测量结果，判断非授权频谱可用，且周期性在非授权频谱上发送和/或接收上述信号。可选的，用户设备10将非授权频谱对于其与其它用户设备间的直连通信为可用状态的信息指示给基站20，和/或将用户设备10已发送和/或接收上述控制信号的信息指示给基站20。Specifically, the base station 20 determines that the unlicensed spectrum is available according to the unlicensed spectrum measurement information reported by the user equipment 10, and instructs the user equipment 10 to start sending and/or receiving the above-mentioned signal through the PDCCH or EPDCCH on the PCell, and the user equipment 10 receives the signal from the base station 20 After the instruction, periodically send and/or receive the above-mentioned signal on the unlicensed spectrum; or, the user equipment 10 judges that the unlicensed spectrum is available according to its own measurement results on the unlicensed spectrum, and periodically sends and/or Receive the above signal. Optionally, the user equipment 10 indicates to the base station 20 the information that the unlicensed spectrum is available for direct communication between it and other user equipment, and/or the information that the user equipment 10 has sent and/or received the above-mentioned control signal Indicated to the base station 20.
同时，在非授权频谱包含多个频率时，用户设备10可以根据基站20的配置及非授权频谱上具体频率范围的可用情况选择相应的可用频率范围发送和/或接收上述控制信号。可选地，用户设备10也可以根据基站20的配置在非授权频谱不可用时，以较低功率和/或不同的周期发送和/或接收上述控制信号。Meanwhile, when the unlicensed spectrum contains multiple frequencies, the user equipment 10 may select a corresponding available frequency range to send and/or receive the control signal according to the configuration of the base station 20 and the availability of specific frequency ranges on the unlicensed spectrum. Optionally, the user equipment 10 may also send and/or receive the above control signal with lower power and/or with a different period when the unlicensed spectrum is unavailable according to the configuration of the base station 20 .
用户设备10在发送和/或接收上述控制信号后，根据接收到的对端用户设备的同步信号和/或发现信号，测量RSRP，或CQI，或路损等信息；并向基站20上报测量结果，用于基站20基于上述控制信号判断用户设备10是否适合维持D2D通信，以及根据非授权频谱的无线参数为用户设备10分配用于数据通信的无线资源。After sending and/or receiving the above-mentioned control signal, the user equipment 10 measures information such as RSRP, or CQI, or path loss according to the received synchronization signal and/or discovery signal of the peer user equipment; and reports the measurement result to the base station 20 The method is used for the base station 20 to judge whether the user equipment 10 is suitable for maintaining D2D communication based on the above control signal, and allocate wireless resources for data communication to the user equipment 10 according to wireless parameters of the unlicensed spectrum.
在非授权频谱可用时，基站20在非授权频谱上发送小区同步信号、参考信号等，用于用户设备10测量非授权频谱上的RSRP或CQI等无线参数的信息，并周期性或者根据测量结果是否大于或小于预设门限而上报给基站20，使得基站20根据非授权频谱的无线参数为用户设备10分配用于数据通信的无线资源。When the unlicensed spectrum is available, the base station 20 sends cell synchronization signals, reference signals, etc. on the unlicensed spectrum, which are used by the user equipment 10 to measure information on wireless parameters such as RSRP or CQI on the unlicensed spectrum, and periodically or according to the measurement results Whether it is greater than or less than the preset threshold is reported to the base station 20, so that the base station 20 allocates radio resources for data communication to the user equipment 10 according to the radio parameters of the unlicensed spectrum.

进一步地，结合图4，若第一用户设备30和第二用户设备40处于不同的基站下辖的小区，则第一处理器12还可用于：根据第一用户设备30与第二用户设备40间交互非授权频谱的占用信息，确定控制信号的接收时间，在接收时间触发第一接收器11通过非授权频谱接收第二用户设备40发送的控制信号；或，根据第一接收器11从第一用户设备30所在基站获取非授权频谱可用的通知，确定控制信号的接收时间，在接收时间触发第一接收器11通过非授权频谱接收第二用户设备40发送的控制信号，其中，该通知为第一用户设备30和第二用户设备40各自所在基站进行非授权频谱占用信息交互的结果，用于指示第一用户设备30和第二用户设备40进行直连通信。Further, referring to FIG. 4 , if the first user equipment 30 and the second user equipment 40 are in cells under the jurisdiction of different base stations, the first processor 12 may also be configured to: according to the first user equipment 30 and the second user equipment 40 exchange the occupancy information of the unlicensed spectrum, determine the receiving time of the control signal, and trigger the first receiver 11 to receive the control signal sent by the second user equipment 40 through the unlicensed spectrum at the receiving time; or, according to the first receiver 11 from the second user equipment 40 A base station where the user equipment 30 is located obtains a notification that the unlicensed spectrum is available, determines the receiving time of the control signal, and triggers the first receiver 11 to receive the control signal sent by the second user equipment 40 through the unlicensed spectrum at the receiving time, wherein the notification is The results of unlicensed spectrum occupancy information exchange between base stations where the first user equipment 30 and the second user equipment 40 are located are used to instruct the first user equipment 30 and the second user equipment 40 to perform direct communication.
实际场景参考图7和图8。该实施例与上述用户设备分别位于不同小区的实施例的区别在于：用户设备间传输同步信号和发现信号的无线资源使用非授权频谱，且该无线资源需要两个基站通过基站间接口(例如X2接口)协商，在两个基站分别为其服务的用户设备所分配的无线资源需保持一致，从而该些用户设备可以在相同的资源上进行控制信号的发送和接收。Refer to Figure 7 and Figure 8 for actual scenarios. The difference between this embodiment and the above-mentioned embodiment in which the user equipments are located in different cells is that: the wireless resources for transmitting synchronization signals and discovery signals between user equipments use unlicensed spectrum, and the wireless resources require two base stations to pass through the inter-base station interface (such as X2 Interface) negotiation, the radio resources allocated by the two base stations to the user equipments serving them respectively need to be consistent, so that these user equipments can send and receive control signals on the same resources.
具体地，分别由不同基站服务的不同用户设备在获取到非授权频谱时，需要该些基站通过X2接口交互，或者通过该些用户设备之间的直接连接进行通知，或者通过该些基站和用户设备均可以访问到的公共信道进行通知，只有在两基站下的非授权频谱上的小区被LTE系统占用的时间发生重叠时，可以进行用户设备之间的数据通信，而用户设备间的同步信号和发现信号才可以通过非授权频谱进行发送。Specifically, when different user equipments served by different base stations obtain unlicensed spectrum, these base stations need to interact through the X2 interface, or notify through the direct connection between these user equipments, or through these base stations and user equipment The public channel that can be accessed by the equipment is notified. Only when the time of the cells on the unlicensed spectrum under the two base stations being occupied by the LTE system overlaps, the data communication between the user equipment can be carried out, and the synchronization signal between the user equipment and discovery signals can be sent through unlicensed spectrum.
本实施例通过基站间或进行直连通信的用户设备间交互非授权频谱的占用信息，确定同步信号和发现信号的发送时机，在非授权频谱无线参数适宜时发送上述信号，例如通过掩码配置使得用户设备仅在非授权频谱可用时，才在授权频谱或非授权频谱上发送控制信号，可以提高上述信号的可靠性，节省授权频谱的无线资源以及用户设备的电池消耗和功率损耗，进而提高通信可靠性；从而节省频谱资源以及UE的电池和功率消耗。In this embodiment, the occupancy information of the unlicensed spectrum is exchanged between the base stations or between the user equipments performing direct communication to determine the timing of sending the synchronization signal and the discovery signal, and send the above-mentioned signals when the wireless parameters of the unlicensed spectrum are suitable, for example, through mask configuration. The user equipment sends control signals on the licensed spectrum or the unlicensed spectrum only when the unlicensed spectrum is available, which can improve the reliability of the above signals, save the wireless resources of the licensed spectrum and the battery consumption and power loss of the user equipment, thereby improving communication. Reliability; thereby saving spectrum resources as well as UE battery and power consumption.
本发明实施例总体上提高了通信的成功率及频谱资源的利用率，使LTE系统中D2D直连通信和异系统之间在符合频谱法规的前提下更合理与更高效地在非授权频谱共存。The embodiment of the present invention generally improves the success rate of communication and the utilization rate of spectrum resources, so that D2D direct communication and different systems in the LTE system can coexist in unlicensed spectrum more reasonably and efficiently under the premise of complying with spectrum regulations. .
