BACKGROUND In a Long Term Evolution (LTE) system, an LTE-Advanced (LTE-A) system, each radio frame length T _f = 307200.7; = 10 ms, one radio frame It includes 20 slots, numbered from 0 to 19, and each slot has a length r _sl . _t = 15360·!; = 0.5 ms. One subframe is defined as two consecutive time slots, that is, the subframe includes time slots 2 and 2 + 1. The standard time length of one uplink subframe is r _subframf; = 3072 (M = lm _S. If a normal cyclic prefix (NCP) is used in the subframe, one uplink subframe contains 14 Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols, from symbol 0 to symbol 13; if extended cyclic prefix (ECP) is used in the subframe ), the 1 uplink subframe includes 12 SC-FDMA symbols, that is, from symbol 0 to symbol 11. The uplink physical channel corresponds to a set of resource elements (Resource Element, RE for short), and is used to carry the high level from the upper layer. The resource unit is the smallest time-frequency resource block, occupies 1 SC-FDMA symbol in the time domain, and occupies 1 sub-carrier in the frequency domain. The physical resource block (Physical Resource Block, PRB for short) is in the frequency domain. Consecutive 12 subcarriers and all SC-FDMA symbols in one time slot in the time domain. Physical Resource Block Pair (PRB pair) is continuous in the frequency domain.

12个子载波以及时域上连续 1个子帧内的所有 SC-FDMA符号组成。上行物理控制信道（Physical Uplink Control Channel, 简称为 PUCCH) 承载的信息有：调度请求（Scheduling Request,简称为 SR)，混合自动重传请求（Hybrid Automatic Repeat Request, 简称为 HARQ)反馈信息，即用户设备（User Equipment, 简称为 UE) 对演进型基站（evolved Node B，简称为 eNB)下行发送的数据接收情况进行正确传输的确认（Acknowledged, 简称为 ACK) /错误传输的确认（Non-acknowledge，简称为 NACK)反馈，以及信道质量报告，包括信道质量指示 /预编码矩阵指示 /秩指示（Channel Quality Indication/Precording Matrix Indicator/Rank Indication, 简称为 CQI/PMI/RI)。物理上行共享信道（Physical Uplink Shared Channel, 简称为 PUSCH)承载用户发送给基站的上行数据。蜂窝通信***由于实现了对有限频谱资源的复用，从而使得无线通信技术得到了蓬勃发展。在蜂窝***中，当两个用户设备（UE)之间有业务需要传输时，用户设备 1 (UE1 ) 到用户设备 2 (UE2) 的业务数据，会首先通过空口传输给基站 1，基站 1 通过核心网将该用户数据传输给基站 2，基站 2 再将上述业务数据通过空口传输给 UE2。 UE2到 UE1的业务数据传输采用类似的处理流程。请参考图 1，图 1是根据相关技术的 UE位于同一基站小区时的蜂窝通信示意图，如图 1所示，当 UE1和 UE2位于同一个蜂窝小区，那么虽然基站 1和基站 2是同一个站点，然而一次数据传输仍然会消耗两份无线频谱资源。由此可见，如果用户设备 1和用户设备 2位于同一小区并且相距较近，那么上述的蜂窝通信方法显然不是最优的通信方式。而实际上，随着移动通信业务的多样化，例如，社交网络、电子支付等在无线通信***中的应用越来越广泛，使得近距离用户之间的业务传输需求日益增长。因此，设备到设备（Device-to-Device, 简称为 D2D) 的通信模式日益受到广泛关注。请参考图 2，图 2是根据相关技术的 D2D通信***的示意图，图 2所示的 D2D 通信模式是指业务数据不经过基站进行转发，而是直接由源用户设备通过空口传输给目标用户设备。这种通信模式区别于传统蜂窝***的通信模式，对于近距离通信的用户来说， D2D不但节省了无线频谱资源，而且降低了核心网的数据传输压力。基于蜂窝网的 D2D通信是一种在***的控制下，在多个支持 D2D功能的终端设备之间直接进行通信的新型技术，它能够减少***资源占用，增加蜂窝通信***频谱效率，降低终端发射功耗，并在很大程度上节省网络运营成本。对于蜂窝通信来说， UE 的业务数据和与其相关的调度信息均来自基站。而对于 D2D通信来说，业务数据直接在 UE之间进行传输，其通信方式无法沿用传统的蜂窝通信方式，然而相关技术中并没有成熟的 D2D调度信息传输方法，因此需要针对 D2D 通信设计专门的调度信息的传输方案。针对相关技术中缺乏针对 D2D通信的专门的调度信息传输方案的问题，目前尚未提出有效的解决方案。发明内容本发明实施例提供了一种设备到设备之间的调度信息的传输方法及装置，以至少解决上述问题。根据本发明实施例的一个方面，提供了一种设备到设备之间的调度信息的传输方法，包括：设备发射端和设备接收端接收来自网络侧的配置指示信息，根据配置指示信息确定具有与配置指示信息对应的资源的上行物理信道；设备发射端和设备接收端通过上行物理信道传输调度信息。优选地，上行物理信道承载调度信息时采用的结构包括：用于传输数据业务的物理上行共享信道（PUSCH) 的结构、或者用于传输上行控制信息的物理上行控制信道 (PUCCH) 的结构。优选地，在设备发射端和设备接收端通过上行物理信道传输调度信息的过程中，当设备发射端通过上行物理信道将调度信息发送给设备接收端时，调度信息包括：用于进行下行接收的第一下行调度信息和用于进行上行发射的第一上行调度信息，设备发射端通过上行物理信道将调度信息发送给设备接收端，包括：设备发射端将第一下行调度信息和第一上行调度信息承载在上行物理信道上，调度设备接收端接收第一下行调度信息和第一上行调度信息。优选地，在设备发射端和设备接收端通过上行物理信道传输调度信息的过程中，当设备接收端通过上行物理信道将调度信息发送给设备发射端时，调度信息包括：用于进行下行发射的第二下行调度信息和用于进行上行接收的第二上行调度信息，设备接收端通过上行物理信道将调度信息发送给设备发射端，包括：设备接收端将第二下行调度信息和第二上行调度信息承载在上行物理信道上，调度设备发射端接收第二下行调度信息和第二上行调度信息。优选地，调度信息的调制方式包括：正交相移键控（QPSK) 或正交振幅调制 ( 16QAM)。优选地，用于传输数据业务的 PUSCH的结构是指，调度信息以资源单元 RE为最小粒度，且利用与 PUSCH相同的子帧结构承载调度信息时采用的结构。优选地，配置指示信息为无线资源控制（RRC)信令， RRC信令能够半静态地配置指示上行物理信道所占的资源，其中，指示方式包括：指示资源的全部资源块（RB) 的索引号，或者指示资源的全部 RB中起始 RB的索引号。优选地，在网络侧向设备发射端和设备接收端发送 RRC 信令时采用的发送方式为：长期演进（LTE) /高级长期演进（LTE-A) 中的 type 0/1/2的资源分配方式。优选地，用于承载调度信息的上行物理信道所占的资源包括：在频域上，占用 RRC 信令指示的 1个或多个 RB; 在时域上，占用子帧的第 1个时隙、第 2个时隙、或第 1 个时隙和第 2个时隙、或者占用用于承载调度信息的单载波-频分多址（SC-FDMA) 符号；调度信息的接收端在接收调度信息的过程中，通过在第 1个时隙、第 2个时隙、或第 1个时隙和第 2个时隙上以 RB为单位进行盲检测的方式，从相应位置上获得调度信息。优选地，用于承载调度信息的上行物理信道所占的资源包括：在频域上，占用 RRC 信令指示的 1或多个 RB; 在时域上，占用解调导频两侧的 SC-FDMA符号，或者占用用于承载调度信息的 SC-FDMA符号；调度信息的接收端在接收调度信息的过程中，通过在解调导频两侧的 SC-FDMA符号上以 RB为单位进行盲检测的方式，从相应位置上获得调度信息。优选地，用于承载调度信息的上行物理信道所占的资源包括：在频域上，占用 RRC 信令指示的全部 RB; 在时域上，占用子帧的第 1个时隙的 1或多个 SC-FDMA符号，或者占用子帧的第 2个时隙上的 1或多个 SC-FDMA符号；调度信息的接收端在接收调度信息的过程中，通过在子帧的第 1个时隙或第 2个时隙中以 SC-FDMA符号为单位进行盲检测的方式，从相应位置上获得调度信息。优选地，用于传输上行控制信息的 PUCCH的结构是指，调度信息以资源单元 (RE) 为最小粒度，且利用与 PUCCH format l/la/lb PUCCH format 2/2a/2b、或 PUCCH format12 subcarriers and all SC-FDMA symbols in one sub-frame in the time domain. The information carried by the Physical Uplink Control Channel (PUCCH) is: Scheduling Request (SR), and Hybrid Automatic Repeat Request (HARQ) feedback information, that is, the user. The device (User Equipment, abbreviated as UE) confirms the correct transmission of the data received by the evolved base station (evolved Node B, eNB for short) (Acknowledged, abbreviated as ACK) / acknowledgment of error transmission (Non-acknowledge, It is abbreviated as NACK), and the channel quality report includes a channel quality indication/Precording Matrix Indicator/Rank Indication (CQI/PMI/RI). Object The Physical Uplink Shared Channel (PUSCH) carries the uplink data sent by the user to the base station. The cellular communication system has realized the multiplex of limited spectrum resources, so that the wireless communication technology has been vigorously developed. In a cellular system, when there is a service between two user equipments (UEs), the service data of the user equipment 1 (UE1) to the user equipment 2 (UE2) is first transmitted to the base station 1 through the air interface, and the base station 1 passes The core network transmits the user data to the base station 2, and the base station 2 transmits the service data to the UE2 through the air interface. The service data transmission from UE2 to UE1 adopts a similar processing flow. Please refer to FIG. 1. FIG. 1 is a schematic diagram of cellular communication when a UE is located in the same base station cell according to the related art. As shown in FIG. 1, when UE1 and UE2 are located in the same cell, then base station 1 and base station 2 are the same site. However, one data transmission still consumes two radio spectrum resources. It can be seen that if the user equipment 1 and the user equipment 2 are located in the same cell and are close to each other, the above-mentioned cellular communication method is obviously not the optimal communication method. In fact, with the diversification of mobile communication services, for example, social networking, electronic payment, and the like are more and more widely used in wireless communication systems, so that the demand for service transmission between close-range users is increasing. Therefore, the communication mode of Device-to-Device (D2D) has received increasing attention. Please refer to FIG. 2. FIG. 2 is a schematic diagram of a D2D communication system according to the related art. The D2D communication mode shown in FIG. 2 refers to that the service data is not forwarded by the base station, but is directly transmitted by the source user equipment to the target user equipment through the air interface. . This communication mode is different from the communication mode of the traditional cellular system. For users of short-range communication, D2D not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network. Cellular network-based D2D communication is a new technology that directly communicates between multiple D2D-enabled terminal devices under the control of the system. It can reduce system resource consumption, increase the spectrum efficiency of cellular communication systems, and reduce terminal transmission. Power consumption, and to a large extent save network operating costs. For cellular communication, the UE's service data and its associated scheduling information are from the base station. For D2D communication, the service data is directly transmitted between the UEs, and the communication method cannot follow the traditional cellular communication method. However, there is no mature D2D scheduling information transmission method in the related art, so it is necessary to design a dedicated D2D communication. The transmission scheme of scheduling information. In view of the lack of a dedicated scheduling information transmission scheme for D2D communication in the related art, an effective solution has not yet been proposed.

Among them, in order to reduce the number of blind detections, it is necessary to limit the number of blind detections of 1-RB, 2-RB, 3-RB, and 4-RB. For example, the number of blind detections by 1-RB pair is up to 4 times; the number of blind detections by 2-RB pair is up to 4 times; the number of blind detections by 3-RB pair is up to 2 times; 4-RB pair The number of blind tests is up to 2 times. The preferred embodiment 7 takes the D2D-grant mapping to the resource of the PUCCH format 3 as an example, and the D2D-grant uses the QPSK to carry the second slot of the RB pair. The physical layer processing process of the D2D-grant transmitter is as follows:

D2D-grant接收端的盲检测过程：从 RRC信令配置好的 RB起始位置开始，或者从 PUCCH所占资源的下一个完整的 RB开始，先按 1 -RB再按 2-RB再按 3-RB最后按 4-RB的顺序进行盲检，即 D2D-grant 接收端先接收 1 -RB的第 2个时隙上的数据，对其进行解调解码看是否是自己需要的调度信息；如果不是再继续接收 2-RB的第 2个时隙，对其进行解调解码看是否是自己需要的调度信息；如果还不是再继续接收 3-RB的第 2个时隙，依次类推，直到接触正确的调度信息为止。同样，为了减少盲检次数需要对 1 -RB、 2-RB , 3-RB和 4-RB 各自的盲检次数进行限定。例如，按 1 -RB pair进行盲检的次数最多为 4次； 2-RB pair 进行盲检的次数最多为 4次；按 3-RB pair进行盲检的次数最多为 2次； 4-RB pair进行盲检的次数最多为 2次。优选实施例八设备到设备之间的调度信息基于 PUCCH结构进行承载的情况下，当 D2D UE在某个子帧上同时发送了 ACK/NACK和 /或 UCI以及 D2D-grant时，如果不加以区分的话，这种传输方式会导致 D2D-gnmt接收端 UE无法识别出哪些是用来传输 ACK/NACK 禾口 /或 UCI 的真正的 PUCCH, 哪些是用来传输 D2D-grant 的 fake-PUCCH。所谓 fake-PUCCH的意思是，借用了 PUCCH的信道结构但实际上传输的是 D2D-gnmt。因此，除用于半静态配置 PUCCH资源的 RRC信令之外，需要额外引入新的 RRC 信令，专门用于半静态的配置传输 D2D-gnmt的 fake-PUCCH资源。具体的配置由基站综合真正的 PUCCH资源的配置情况来决定 fake-PUCCH资源的配置，以达到避免干扰的目的。结合现有的配置方式方案，新引入的 RRC信令可以仿照 PUCCH format 3的格式，例如， fake-PUCCH SEQUENCE (SIZE (1..2)) OF INTEGER (0..549), 或者 fake-PUCCH SEQUENCE (SIZE (1..4)) OF INTEGER (0..549) 即基站为 fake-PUCCH配置最多 2或 4个 RB用于承载 D2D-grant，并通过调度将这些 RB与真正的 PUCCH format所占 RB进行规避。此外，高层一次性配置下来的 RB可以不完全用作 fake-PUCCH, 未占用的 RB可以用于数据业务的传输。优选实施例九对于实施例八中所描述的干扰问题，还可以利用盲检测的方式进行干扰避免。该方式下，基站不为 fake-PUCCH配置专门的资源，即根据每个子帧中 PUCCH format 不同的发射情况，灵活的决定使用哪种 PUCCH format进行 D2D-grant 的发送。而 D2D-grant接收端则对各种 PUCCH format进行盲检测，以区分是真正的 PUCCH还是 D2D-granto 具体地，在非载波聚合的场景下， PUCCH format 3 所在资源可以转化为 fake-PUCCH资源用来承载 D2D-grant。而 D2D-grant接收端在接收 PUCCH format 3 资源时，并不知道接收到的是 ACK/NACK还是 D2D-gnmt，此时，接收端开始执行盲检测，即先按照真正的 PUCCH format 3进行解调解码，如果发现解码错误，再按照 fake-PUCCH进行解调解码，直到解调出正确的数据为止。此外，如果某子帧上不需要发送 PUCCH format 1或 2时，或者 PUCCH format 1 或 2 的资源有大量闲置时，也可以将这部分资源转化为 fake-PUCCH 资源用来承载 D2D-grant, 同样地， D2D-grant接收端通过盲检测加以区分。考虑到盲检复杂度，需要设计合理的盲检方法。该方案更加适合于点对点的 D2D传输，好处是不会引入任何信令开销，同时利用闲置的 PUCCH资源来发送 D2D-gnmt提高了资源利用率；缺点是增加了 D2D UE的检测复杂度。采用上述实施例提供的设备到设备之间的调度信息的传输方法，设备发射端和设备接收端通过上行物理信道传输设备到设备之间的调度信息的方式，解决了相关技术中缺乏针对 D2D通信的专门的调度信息传输方案的问题，进而达到了提供了一种成熟的设备到设备（D2D) 调度信息的传输方法的效果。图 14是根据本发明实施例的设备到设备之间的调度信息的装置的结构框图，该装置用以实现上述实施例提供的设备到设备之间的调度信息的传输方法，如图 14所示，该装置包括：接收模块 10、确定模块 20以及传输模块 30。其中，接收模块 10，设置为接收来自网络侧的配置指示信息；确定模块 20，连接至接收模块 10，设置为根据配置指示信息确定具有与配置指示信息对应的资源的上行物理信道；传输模块 30，连接至确定模块 20，设置为通过上行物理信道在设备发射端和设备接收端之间传输调度信息。在本实施例中，上行物理信道承载调度信息时采用的结构包括：用于传输数据业务的物理上行共享信道（PUSCH) 的结构、或者用于传输上行控制信息的物理上行控制信道（PUCCH) 的结构。图 15是根据本发明优选实施例的设备到设备之间的调度信息的装置的结构框图，在传输模块通过上行物理信道向设备接收端发送调度信息的过程中，调度信息包括：用于进行下行接收的第一下行调度信息和用于进行上行发射的第一上行调度信息，如图 15所示，在该优选实施例提供的装置中，传输模块 30包括：第一调度单元 32，设置为将第一下行调度信息和第一上行调度信息承载在上行物理信道上，调度设备接收端接收第一下行调度信息和第一上行调度信息。在传输模块通过上行物理信道向设备发送端发送调度信息的过程中，调度信息包括：用于进行下行接收的第二下行调度信息和用于进行上行发射的第二上行调度信息，如图 15所示，在该优选实施例提供的装置中，传输模块 30还包括：第二调度单元 34，设置为将第二下行调度信息和第二上行调度信息承载在上行物理信道上，调度设备发送端接收第二下行调度信息和第二上行调度信息。优选地，调度信息的调制方式包括：正交相移键控（QPSK) 或正交振幅调制The blind detection process of the D2D-grant receiving end: starting from the RB starting position configured by the RRC signaling, or starting from the next complete RB of the resource occupied by the PUCCH, first pressing 1-RB and then pressing 2-RB and then pressing 3- The RB finally performs blind detection in the order of 4-RB, that is, the D2D-grant receiver first receives the data on the second time slot of the 1-RB, and demodulates and decodes it to see if it is the scheduling information that it needs; if not Then continue to receive the second time slot of the 2-RB, demodulate and decode it to see if it is the scheduling information that it needs; if it is not yet to continue to receive the second time slot of the 3-RB, and so on, until the contact is correct The scheduling information is up. Similarly, in order to reduce the number of blind detections, it is necessary to limit the number of blind detections for each of 1-RB, 2-RB, 3-RB, and 4-RB. For example, the number of blind checks performed by 1-RB pair is up to 4 times; 2-RB pair The number of blind detections is up to 4 times; the number of blind detections by 3-RB pair is up to 2 times; the number of blind inspections by 4-RB pair is up to 2 times. In the case of the preferred embodiment 8 device-to-device scheduling information based on the PUCCH structure, when the D2D UE simultaneously transmits ACK/NACK and/or UCI and D2D-grant on a certain subframe, if no distinction is made, This transmission method will cause the D2D-gnmt receiver UE to not recognize which are the real PUCCHs used to transmit ACK/NACK and/or UCI, and which are the fake-PUCCHs used to transmit D2D-grants. The so-called fake-PUCCH means that the channel structure of the PUCCH is borrowed but the D2D-gnmt is actually transmitted. Therefore, in addition to RRC signaling for semi-statically configuring PUCCH resources, it is necessary to additionally introduce new RRC signaling, which is specifically used for semi-static configuration transmission of D2D-gnmt's fake-PUCCH resources. The specific configuration is determined by the base station synthesizing the configuration of the real PUCCH resources to determine the configuration of the fake-PUCCH resources to avoid interference. In combination with the existing configuration scheme, the newly introduced RRC signaling can be modeled in the format of PUCCH format 3, for example, fake-PUCCH SEQUENCE (SIZE (1..2)) OF INTEGER (0..549), or fake-PUCCH. SEQUENCE (SIZE (1..4)) OF INTEGER (0..549) That is, the base station configures up to 2 or 4 RBs for the fake-PUCCH to carry the D2D-grant, and schedules these RBs with the real PUCCH format. Take up RB to circumvent. In addition, the RBs configured by the upper layer at one time may not be completely used as the fake-PUCCH, and the unoccupied RBs may be used for the transmission of data services. Preferred Embodiment 9 For the interference problem described in Embodiment 8, interference avoidance can also be performed by means of blind detection. In this mode, the base station does not configure a dedicated resource for the fake-PUCCH, that is, according to the different transmission conditions of the PUCCH format in each subframe, it is flexible to decide which PUCCH format to use for D2D-grant transmission. The D2D-grant receiving end performs blind detection on various PUCCH formats to distinguish whether it is a real PUCCH or a D2D-granto. Specifically, in a non-carrier aggregation scenario, the resource in which the PUCCH format 3 is located can be converted into a fake-PUCCH resource. To host the D2D-grant. The D2D-grant receiver is receiving PUCCH format 3 When the resource is not known, it is ACK/NACK or D2D-gnmt. At this time, the receiving end starts to perform blind detection, that is, demodulation and decoding according to the real PUCCH format 3. If a decoding error is found, follow the fake- The PUCCH performs demodulation decoding until the correct data is demodulated. In addition, if PUCCH format 1 or 2 does not need to be sent in a certain subframe, or if the resources of PUCCH format 1 or 2 are largely idle, this part of the resources can also be converted into a fake-PUCCH resource to carry the D2D-grant. The D2D-grant receiver is distinguished by blind detection. Considering the complexity of blind detection, it is necessary to design a reasonable blind detection method. The scheme is more suitable for point-to-point D2D transmission, and the advantage is that no signaling overhead is introduced, and the use of idle PUCCH resources to transmit D2D-gnmt improves resource utilization; the disadvantage is that the detection complexity of the D2D UE is increased. The device-to-device scheduling information transmission method provided by the foregoing embodiment is used, and the device transmitting end and the device receiving end transmit the scheduling information between the device and the device through the uplink physical channel, thereby solving the lack of the related technology in the D2D communication. The problem of a dedicated scheduling information transmission scheme, in turn, provides the effect of providing a mature device-to-device (D2D) scheduling information transmission method.
