  • the goal of the mobile relay network is to provide better broadband access capability for a group of users in a common mobile state.
  • One of the typical application scenarios is to provide passengers with better access services by deploying mobile relay nodes on vehicles with higher user density (eg, buses, buses, trains, ships, etc.).
  • mobile relay technology has many advantages. On the one hand, passengers can increase single-user throughput by utilizing a good backhaul link between the relay node and the base station.

  • an antenna deployed outside the vehicle can be utilized to avoid penetration loss caused by the vehicle.
  • the relay node itself can further improve the performance of the backhaul link by providing a better performance wireless transceiver and performing more complex data processing (eg, Doppler effect compensation).
  • the base station can also pass the distance Larger different relay service areas multiplex the same radio resources to increase the overall throughput of the entire cell, thereby obtaining resource multiplexing gain.
  • the mobile relay service area generally overlaps with the macro cell served by the base station, so when the relay service area shares the radio resources of the macro cell served by the base station , the backhaul link between the mobile relay node and the base station, the interference between the relay access link between the mobile relay node and the passenger, and the direct connection between the other directly connected users and the base station must be Consider it.
  • a non-transparent relay mode that is, the relay node is equivalent to a small base station
  • different subframes must be used to avoid interference between the relay access link and the direct connection link. .
  • the resource partitioning mode of the sub-frame level is very large, and the access resource configuration of the relay node cannot be changed in real time with the traffic volume, thereby easily causing a large waste of resources.
  • the base station itself must support the transmission of the common reference signal in the relay access subframe, which will interfere with the data transmission of the relay node. Therefore, the technical solution provided by the embodiment of the present invention is more focused on a solution in a transparent relay mode.
  • the user In the transparent relay mode, the user still connects to the base station on the control plane, obtains resource scheduling information from the base station, and receives data transmitted from the relay node or transmits data to the relay node under the control of the base station. Since the passengers are inside the vehicle and move with the relay node, although the surrounding environment is constantly changing, the relay access link between the passenger and the relay node can always maintain good performance. And because the distance between the relay node and the passenger is small, a high-order modulation and coding method can be adopted on the relay access link, for example, 64QAM or even 256QAM. Therefore, for passengers, the performance of the relay access link is far superior to the direct connection link between it and the base station.

  • the aggregation level 8 can be used, that is, one DCI unit is mapped into 8 CCEs, thereby greatly reducing the effective code rate of the DCI during transmission.
  • a significant drawback in the transparent relay mode is that the passengers still need to obtain resource scheduling information through the poorly connected direct connection link, and the related signaling overhead is very large. This drawback will become more pronounced especially when there are many passengers in the vehicle who need broadband access. For a regular passenger car, the average number of passengers can reach 50 to 100. With the rapid development of various types of services, it is foreseeable that a considerable proportion of passengers will access various broadband services during the ride.

Description

资源调度信息的指示、分配方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种资源调度信息的指示、分配方法及装置。
背景技术
移动互联网、物联网以及其他业务应用的迅猛发展已经成为推动第五代移动通信技术(5G)发展的主要驱动力。他们迫切要求5G具有媲美光纤的接入速率、千亿设备的连接能力、完美的实时体验以及随时随地的无线宽带接入能力。此外，能耗效率、频谱效率和峰值速率等重要指标也需要在5G系统设计时加以综合考虑。中国在2013年成立了IMT-2020(5G)推进组推进5G技术的发展。根据国际整体情况，预计2015年将形成5G愿景、关键能力需求及频谱规划，之后将启动5G标准化工作，并在2020年后开始商用。在国际标准方面，长期演进增强(LTE-Advanced)的技术标准主要在第三代合作伙伴计划(3GPP)国际标准化组织制订。业界初步认为在3GPP R14阶段(预计于2016年)将启动面向5G的标准研究工作。
在未来的移动网络中，业务量需求会不断提高、终端数目和种类也不断呈爆发式增长、用户服务质量(QOS)等需求差异化明显，这些都需要针对不同场景研究对应的解决方案。作为5G的重要场景之一，移动中继网络的目标是能够为一组处于共同移动状态中的用户提供更好的宽带接入能力。这其中一个典型的应用场景就是在用户密度较高的交通工具(例如：公共汽车、客车、火车、轮船等)上通过部署移动中继节点来为乘客提供更好的接入服务。在这种场景下，移动中继技术具有诸多优势。一方面，乘客可以通过利用中继节点和基站之间良好的回传链路来增加单用户吞吐量。如果采用传统的基站接入方式，乘客与基站之间的直连接入链路的信道质量会受到不断变化的周围环境的影响；并且，交通工具的穿透损耗以及运动引起的多普勒效应都会使信道质量进一步恶化。例如：实测的车辆的穿透损耗一般在3.2至23.8dB之间。通过引入中继节点，可以利用部署在交通工具外部的天线来避免交通工具所带来的穿透损耗。此外，中继节点本身还可以通过配备性能更好的无线收发机，及进行更复杂的数据处理(例如：多普勒效应的补偿)来进一步提升回传链路的性能。在这种情况下，即使移动中继节点需要额外的资源来与乘客进行第二跳的信息交互，乘客的单用户吞吐量以及整体的频谱效率仍然可以得到较大改善。此外，基站还可以通过在距离 较大的不同中继服务区域复用相同的无线资源来增加整个小区的总体吞吐量，从而获得资源复用增益。
但是，在移动中继网络中，由于中继节点的移动特性，移动中继服务区一般总是和基站所服务的宏小区重叠，因此当中继服务区共享基站所服务的宏小区的无线资源时，移动中继节点和基站之间的回传链路，移动中继节点和乘客之间的中继接入链路以及其他直连用户和基站之间的直连接入链路之间的干扰必须加以考虑。在此种情况下，如果采用非透明的中继方式(即中继节点相当于一个小基站)，中继接入链路和直连接入链路之间必须通过采用不同的子帧来规避干扰。这种子帧级别的资源划分方式粒度很大，并且中继节点的接入资源配置无法随业务量进行实时变化，由此很容易带来较大的资源浪费。另外，基站本身为支持传统用户必须在中继接入子帧仍然保持公共参考信号的发送，这将对中继节点的数据发送造成干扰。故而，本发明实施例所提供的技术方案更加关注于透明的中继方式下的解决方案。
在透明的中继方式下，用户在控制面上仍然是与基站进行相互连接的，从基站获得资源调度信息，并在基站的控制下接收从中继节点发送的数据或向中继节点发送数据。由于乘客在交通工具内部并随着中继节点一起运动，虽然周边环境不断发生变化，但是乘客与中继节点之间的中继接入链路却能够一直保持良好的性能。并且由于中继节点和乘客之间的距离较小，中继接入链路上可以采用高阶的调制编码方式，例如：64QAM，甚至256QAM。所以，对于乘客而言，中继接入链路的性能要远远优于其与基站之间的直连接入链路。
但是在透明的中继方式中，用户仍然需要从基站获得资源调度信息，即通过解码直连接入链路上的物理下行控制信道(PDCCH)中的控制信道单元(CCE)获得。在LTE系统中，基站在PDCCH中固定地采用QPDK加以调整，并规定了不同的聚合等级(1、2、4、8)来确保其在不同信道条件下的正确接收。当信道条件较好时可以采用聚合等级1，即将一个下行控制信息(DCI)单元映射到一个CCE中。而当信道条件较差时则可以采用聚合等级8，即将一个DCI单元映射到8个CCE中，从而大大降低了DCI在传输过程中的有效码率。故而，透明的中继方式中存在的一个明显缺陷在于：由于乘客仍然需要通过性能较差的直连接入链路获取资源调度信息，而相关的信令开销非常大。特别是当交通工具中有很多乘客需要进行宽带接入时，这种缺陷将愈发突出。对于一辆普通客车而言，一般的乘客数量可以达到50～100名。随着多种类型业务的飞速发展，可以预见会有相当比例的乘客在乘车期间接入各种宽带业务。由此可见，如何减少透明的中继方式中无线资源调度的信令开销是个亟待解决的关键问题。

步骤S1：为移动中继节点以及部分或全部UE分配公共的小区无线网络临时标识(C-RNTI)，其中，C-RNTI用于标识和加扰资源调度信息。
在优选实施例中，基站首先在其PDCCH中为移动中继节点及其下属的所有乘客分配一个下行共享数据信道(PDSCH)中的索引资源块，该索引资源块设置为移动中继节点发送详细的资源调度信息。优选的，基站可以使用预先为移动中继节点及其下属的所有乘客分配的公共的小区无线网络临时标识(C-RNTI)来标识和加扰该索引资源块所承载的资源调度信息。

优选地，在步骤S104，发送资源调度信息之后，还可以包括以下步骤：
步骤S5：接收来自于部分或全部UE的中继分配索引取消请求消息，其中，中继分配索引取消请求消息中携带有取消原因；

在优选实施例中，在乘客发现应当回到基站服务的小区之后，可以向基站发送一个中继分配索引取消请求消息，其中，该中继分配索引取消请求消息中可以携带有取消原因，例如：检测到中继接入链路的信道质量变差。基站在接收到上述中继分配索引取消请求消息后可以返回中继分配索引取消响应消息，用来接受或拒绝该中继分配索引取消请求消息。在该优选实施例中，在中继分配索引取消响应消息中可以定义一 个时间参考点，例如：无线子帧号，来协调上述的无线资源的调度指示方法的取消时间。
在优选实施过程中，上述中继分配索引激活请求消息、中继分配索引激活响应消息、中继分配索引激活确认消息、中继分配索引取消请求消息以及中继分配索引取消响应消息中的至少之一可以采用一个新定义的无线资源控制(RRC)消息，或者其内容可以包含在其他LTE已有的RRC消息中。
图2是根据本发明实施例的资源调度信息的分配方法的流程图。如图2所示，该方法可以包括以下处理步骤：
步骤S202：接收来自于基站的索引资源指示信息，其中，索引资源指示信息用于指示自身以及自身下属的部分或全部UE待使用的索引资源块；
步骤S204：根据索引资源指示信息在索引资源块中将部分或全部UE的资源调度信息发送至部分或全部UE。
在优选实施过程中，可以在索引资源块中按照预设的资源分配指示格式将部分或全部UE的资源调度信息发送至部分或全部UE。
优选地，上述索引资源指示信息中还可以携带有预设的资源分配指示格式，其中，预设的资源分配指示格式是在基站确定当前支持多种类型的资源分配指示格式后携带在索引资源指示信息中，以从索引资源指示信息中获知预设的资源分配指示格式。
优选地，将资源调度信息发送至部分或全部UE可以包括但不限于以下方式之一：
方式一、按照基站预先决定的中继资源分配指示格式将资源调度信息发送至部分或全部UE；
方式二、在根据部分或全部UE中与每个UE对应的中继接入链路状态及其业务流状态进行资源再分配后，按照自身决定的中继资源分配指示格式将资源调度信息发送至部分或全部UE。
在优选实施例中，基站可以根据业务状况为中继网络的所有乘客分配一个大于预设阈值的资源块，然后将相关信息通过回传链路通知给移动中继节点。移动中继节点在根据每名乘客所使用的中继接入链路状态及其业务流状态做进一步地资源分配后，在上述PDSCH的索引资源块中按照预设的中继调度格式发送与每名乘客对应的资源调度信息。在该优选实施例中，该中继调度格式信息可以在上述资源调度信息中预先 通知给所有乘客。当然，基站也可以自主决定所有乘客具体的资源分配方式，然后通知给移动中继节点。此后，移动中继节点直接在上述PDSCH的索引资源块中按照预设的中继调度格式发送与每名乘客对应的资源调度信息。移动中继节点下属各个乘客可以根据上述PDSCH的索引资源块上的资源调度信息进行数据发送和/或接收。
优选地，上述预先决定的或自身决定的中继资源分配指示格式可以采用的调度格式包括但不限于以下之一：
(1)独立的资源分配指示格式，其中，独立的资源分配指示格式中包含多个独立的调度指示单元，每个调度指示单元均包括：调度指示长度信息区域、用户身份标识区域、下行控制信息DCI信息区域以及循环冗余码CRC校验区域；
(2)综合的资源分配指示格式，其中，综合的资源分配指示格式中包含总体长度区域、多个独立的调度指示单元以及整体CRC校验区域，每个调度指示单元均包括：用户身份标识区域、DCI格式指示区域以及DCI信息区域。
为了充分利用传统LTE中已经定义的DCI调度格式，以减少相关的标准化工作，本发明实施例在重用已有的DCI调度格式的基础上定义了两种PDSCH中可能采用的中继资源分配指示格式。
第一种、是独立的资源分配指示格式，即中继调度由多个独立的调度指示单元构成，其中，每个调度指示单元可以包括但不限于以下信息区域：调度指示长度信息区域、乘客身份标识区域、具体的DCI信息区域以及相应的CRC检测区域。每个调度指示单元所采用的DCI格式可以通过长度信息获得。
第二种、是综合的资源分配指示格式，这种格式由总长度区域、各个调度指示单元以及总CRC校验区域组成，其中，每个调度指示单元又可以进一步分为下列区域：身份标识区域、DCI格式指示区域、DCI信息区域，其中，DCI格式指示区域可以是一个4比特的定长字段，用来指示现在的LTE系统所支持的各种DCI格式，可以包括但不限于：格式0～4，1A～1D，2A～2D，3A共14种格式。
需要说明的是，综合的调度指示格式虽然可以减少开销，但是由于只进行一次整体的CRC校验，其只适用于中继接入链路质量相对良好的情况。
上述乘客的身份标识既可以是LTE系统中基站为乘客分配的C-RNTI，也可以是LTE网络中其他用于标识用户的设备号码。
下面将结合图3至图8所示的优选实施方式对上述优选实施过程做进一步地描述。
图3是根据本发明优选实施例的资源调度信息分配的应用场景示意图。如图3所示，在LTE基站所服务的宏小区中存在某个交通工具。交通工具内部有多名乘客通过设置在该交通工具上的移动中继节点与基站进行通信，其中，基站与移动中继节点之间的链路称为中继回传链路，基站与乘客之间的链路称为直连接入链路；移动中继节点与乘客之间的链路称为中继接入链路。如前所述，由于存在多普勒效应、交通工具的穿透损耗以及传输距离等多方面原因，中继接入链路的质量要远远优于直连接入链路。并且，由于乘客和交通工具的相对静止，中继接入链路性能十分稳定，因此，为了节约信令开销，本发明实施例所提供的技术方案可以利用中继接入链路来传输乘客的资源分配指示信息。
图4是根据本发明优选实施例的在移动中继下乘客资源分配指示的流程图。如图4所示，该方法可以包括如下步骤：
步骤S402-步骤S404：基站首先在其PDCCH中通知移动中继节点及其下属的所有乘客一个下行共享数据信道(PDSCH)资源块，该资源块被称为索引资源块，其中，该索引资源块设置为移动中继节点发送详细的资源调度信息。为了能够使得移动中继节点及其下属的所有乘客均能获取到索引资源块的信息，基站需要预先为移动中继节点及其下属的所有乘客分配一个公共的小区无线网络临时标识(C-RNTI)来标识和加扰该索引资源块的DCI调度信息。
步骤S406-步骤S408：基站可以根据所服务小区的整体业务状况为移动中继网络中需要服务的所有乘客分配一个大于预设阈值的资源块，并将相关信息通过中继回传链路通知移动中继节点。移动中继节点在根据每名乘客具体的中继接入链路状态以及其业务流状态做进一步的资源分配后，在上述PDSCH的索引资源块中按照预设的中继调度格式发送与每名乘客对应的资源调度信息。在系统支持多种中继资源分配指示格式的情况下，其所采用格式可以在上述步骤的索引资源块的DCI信息中预先通知所有乘客。而如果系统仅支持一种缺省分配指示格式，则无需对LTE中已有的DCI格式作任何修改。当然，基站也可以自主决定所有乘客具体的资源分配方式，然后通知给移动中继节点。此后，移动中继节点直接在上述PDSCH的索引资源块中按照预设的中继调度格式发送与每名乘客对应的资源调度信息。
步骤S410：移动中继节点下属各个乘客可以根据上述PDSCH的索引资源块上的资源调度信息进行数据发送和/或接收。
图5是根据本发明优选实施例的移动中继下乘客资源分配指示的激活过程的流程图。如图5所示，该方法可以包括如下步骤：
步骤S502-步骤S504：乘客在通过与移动中继节点的发现过程发现应当启用移动中继节点之后，向基站发送中继分配索引激活请求消息，其中，该中继分配索引激活请求消息中可以携带有激活原因，例如：检测到中继接入链路的信道质量大于预设阈值。
步骤S506：基站在接收到中继分配索引激活请求消息后，将会返回中继分配索引激活响应消息，用以接受或拒绝该中继分配索引激活请求消息。如果基站接受中继分配索引激活请求消息，那么在中继分配索引激活响应消息中应该携带有上述基站为移动中继节点预先分配的公共的小区无线网络临时标识(C-RNTI)。然后，基站将以上述无线资源分配指示方法发送调度信息。为了同步整个过程，在中继分配索引激活响应消息中可以定义一个起始时间参考点，例如：无线子帧号，用来协调采用上述的无线资源分配指示方法的起始时间。
步骤S508-步骤S512：在某些情况下，乘客可以在接收到来自于基站的接受激活请求的中继分配索引激活响应消息后再发送一个中继分配索引激活确认消息。此时，上述起始时间参考点信息应该携带在中继分配索引激活确认消息中。移动中继节点下属各个乘客可以根据上述PDSCH的索引资源块上的资源调度信息进行数据发送和/或接收。
以上步骤提到的各个消息可以是一个新定义的无线资源控制(RRC)消息，或者其内容可以包含在其他LTE已有的RRC消息中。
图6是根据本发明优选实施例的移动中继下乘客资源分配指示的取消过程的流程图。如图6所示，该方法可以包括如下步骤：
步骤S602-步骤S604：乘客在发现应该离开移动中继节点而回到基站服务的小区之后，向基站发送一个中继分配索引取消请求消息，其中，该中继分配索引取消请求消息中可以携带有取消原因，例如：检测到中继接入链路的信道质量变差。
步骤S606-步骤S608：基站在接收到上述中继分配索引取消请求消息后可以返回中继分配索引取消响应消息，用来接受或拒绝该中继分配索引取消请求消息。同样，在中继分配索引取消响应消息中可以定义一个时间参考点，例如：无线子帧号，来协调上述的无线资源的调度指示方法的取消时间。移动中继节点下属各个乘客可以根据上述PDSCH的索引资源块上的资源调度信息进行数据发送和/或接收。
以上步骤中提到的各个消息可以是一个新定义的无线资源控制(RRC)消息，或者其内容可以包含在其他已有的RRC消息中。
图7是根据本发明优选实施例的一种PDSCH中的独立资源分配指示格式示意图。如图7所示，为了充分利用传统LTE中已经定义的DCI调度格式，以减少相关的标准化工作，本发明实施例在重用已有的DCI调度格式的基础上定义了两种PDSCH中可能采用的中继资源分配指示格式。在图7中所描述的是独立的中继资源分配指示格式，其中，中继调度由多个独立的调度指示单元构成，其中，每个调度指示单元可以包括但不限于以下信息区域：调度指示长度信息区域、乘客身份标识区域、具体的DCI信息区域以及相应的CRC检测区域。每个调度指示单元所采用的DCI格式可以通过长度信息获得。
图8是根据本发明优选实施例的一种PDSCH中的总体资源分配指示格式示意图。如图8所示，在此种格式中，所有用户的调度信息集中到一起共用一个CRC校验区域，并且只提供了所有调度信息的总长度信息。这种格式由总长度区域、各个调度指示单元以及总CRC校验区域组成，其中，每个调度指示单元又可以进一步分为下列区域：身份标识区域、DCI格式指示区域、DCI信息区域，其中，DCI格式指示区域可以是一个4比特的定长字段，用来指示现在的LTE系统所支持的各种DCI格式，可以包括但不限于：格式0～4，1A～1D，2A～2D，3A共14种格式。
需要说明的是，综合的调度指示格式虽然可以减少开销，但是由于只进行一次整体的CRC校验，其只适用于中继接入链路质量相对良好的情况。
另外，在上述图7和图8中提到的乘客的身份标识既可以是LTE系统中基站为乘客分配的C-RNTI，也可以是LTE网络中其他用于标识用户的设备号码。
图9是根据本发明实施例的资源调度信息的指示装置的结构框图。如图9所示，该资源调度信息的指示装置可以包括：下发模块100，设置为向移动中继节点以及该移动中继节点下属的部分或全部用户设备UE下发索引资源指示信息，其中，索引资源指示信息用于指示移动中继节点和部分或全部UE待使用的索引资源块；第一分配模块102，设置为在索引资源块中发送部分或全部UE的资源调度信息，其中，资源调度信息由移动中继节点发送至部分或全部UE。
采用如图9所示的装置，解决了相关技术中如何尽量减少透明的中继方式中无线资源调度的信令开销的问题，可以有效地降低调度信息传输所消耗的信令开销。
在优选实施过程中，上述索引资源块可以为PDSCH资源块。

优选地，上述中继分配索引激活响应消息中还可以携带有预定义的起始时间参考点信息，其中，起始时间参考点信息用于协调开始执行资源调度信息的指示方法的起始时间。

优选地，上述中继分配索引激活请求消息、中继分配索引激活响应消息、中继分配索引激活确认消息、中继分配索引取消请求消息以及中继分配索引取消响应消息中的至少之一可以采用新定义的无线资源控制(RRC)消息或者包含在现有的RRC消息中。
图11是根据本发明实施例的资源调度信息的分配装置的结构框图。如图11所示，该资源调度信息的分配装置可以包括：接收模块200，设置为接收来自于基站的索引资源指示信息，其中，索引资源指示信息用于指示自身以及自身下属的部分或全部UE 待使用的索引资源块；分配模块202，设置为根据索引资源指示信息在索引资源块中将部分或全部UE的资源调度信息发送至部分或全部UE。
优选地，分配模块202，设置为在索引资源块中按照预设的资源分配指示格式将部分或全部UE的资源调度信息发送至部分或全部UE。
优选地，上述索引资源指示信息中还可以携带有预设的资源分配指示格式，其中，预设的资源分配指示格式是在基站确定当前支持多种类型的资源分配指示格式后携带在索引资源指示信息中，以使索引资源指示信息中获知预设的资源分配指示格式。
优选地，分配模块202可以包括：第一分配单元(图中未示出)，设置为按照基站预先决定的中继资源分配指示格式将资源调度信息发送至部分或全部UE；第二分配单元(图中未示出)，设置为在根据部分或全部UE中与每个UE对应的中继接入链路状态及其业务流状态进行资源再分配后，按照自身决定的中继资源分配指示格式将资源调度信息发送至部分或全部UE。
优选地，上述中继资源分配指示格式可以包括但不限于以下之一：
(1)独立的资源分配指示格式，其中，独立的资源分配指示格式中包含多个独立的调度指示单元，每个调度指示单元均包括：调度指示长度信息区域、用户身份标识区域、下行控制信息(DCI)信息区域以及循环冗余码(CRC)校验区域；
(2)综合的资源分配指示格式，其中，综合的资源分配指示格式中包含总体长度区域、多个独立的调度指示单元以及整体CRC校验区域，每个调度指示单元均包括：用户身份标识区域、DCI格式指示区域以及DCI信息区域。
从以上的描述中，可以看出，上述实施例实现了如下技术效果(需要说明的是这些效果是某些优选实施例可以达到的效果)：采用本发明实施例所提供的技术方案，可以大大减小调度信息传输的信令开销。由于所有乘客的调度信息可以在采用高阶调制的中继接入链路传输，因而可以有效地降低调度信息传输所消耗的信令开销。例如，当中继接入链路使用16QAM，相比与基站的QPSK，即使假设所有相关的DCI单元都采用最优的聚合度1，仍然可以节省大约一半的无线资源。这种开销的减少在中继接入链路使用更高阶调制时会更加显著。其次，采用本发明实施例所提供的技术方案，无需对传统的LTE系统做出太多改变，不需要为实现中继节点侧的接入调度在基站侧定义任何新的DCI格式，其对现有的LTE系统影响极小；并且还能够与传统的LTE系统相互兼容，即可以和传统LTE的调度指示一起使用。最后，采用本发明实施例所提供的技术方案，不仅适用于中继区域和宏基站服务区域采用相同信道的场景，同样 也适用于中继区域和宏基站服务区域采用不同信道的场景。而在后一场景中，中继接入信道中可以没有PDCCH信道。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
如上所述，本发明实施例提供的一种资源调度信息的指示、分配方法及装置具有以下有益效果：可以大大减小调度信息传输的信令开销。由于所有乘客的调度信息可以在采用高阶调制的中继接入链路传输，因而可以有效地降低调度信息传输所消耗的信令开销。此外，采用本发明实施例所提供的技术方案，无需对传统的LTE系统做出太多改变，不需要为实现中继节点侧的接入调度在基站侧定义任何新的DCI格式，其对现有的LTE系统影响极小；并且还能够与传统的LTE系统相互兼容，即可以和传统LTE的调度指示一起使用。不仅如此，采用本发明实施例所提供的技术方案，不仅适用于中继区域和宏基站服务区域采用相同信道的场景，同样也适用于中继区域和宏基站服务区域采用不同信道的场景。而在后一场景中，中继接入信道中可以没有PDCCH信道。
