具体实施方式
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。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)通用分组无线业务(General Packet Radio Service，GPRS)系统、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide  Interoperability for Microwave Access，WiMAX)通信系统，以及未来的5G通信系统等。
本发明结合终端描述了各个实施例。终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端可以指用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备等。
本发明结合基站描述了各个实施例。基站可以是用于与终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者该基站可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备等。
图1是本发明一个实施例的指示资源的方法100的示意性流程图。如图1所示，该方法100涉及基站和终端，包括但不限于以下步骤。
S110，基站根据系统的设置以及当前资源的分配情况，生成资源指示信道。该资源指示信道用于指示第一时频资源和使用该第一时频资源时的通信参数，该资源指示信道占用第二时频资源。其中，示意性地，如图2A所示，第一时频资源R包括第二时频资源r(阴影部分所示)，即第二时频资源所占用的时频范围位于第一时频资源所占用的时频范围内。
应理解，本发明实施例的第二时频资源r可以包括至少一个时频单元。当第二时频资源r只包括一个时频单元(例如图2A所示的第一时频单元r-1)时，第一时频单元r-1对应的时间范围为系统设定的时间点，第一时频单元r-1对应的频率范围为系统设定的频率栅格(Frequency Raster，一般可记为fR，例如fR＝K×100KHz，K为和频段相关的因子)。
当第二时频资源r包括多个时频单元时，可以在第一时频单元r-1中包括指示资源指示信道由第一时频单元r-1扩展为占用多个时频单元(例如图 2B所示的第一时频单元r-1、第二时频单元r-2和第三时频单元r-3)，即扩展为占用第二时频资源r的信息。此处，第一时频单元r-1扩展可以向时间范围扩展，也可向频率范围扩展，本发明实施例对此不作限定。第一时频单元r-1对应的时间范围仍为系统设定的时间点，第一时频单元r-1对应的频率范围仍为系统设定的频率栅格。
由此，资源指示信道是分布在时间范围和频率范围较为固定的一些资源上，并且资源指示信道本身所占用的时频资源较少，用于指示附近的更大的时频资源的分配和通信参数。基于资源指示信道的上述特点，可以形象地称该资源指示信道为“锚信道”。除图2A至图2I以及图3示出的第二时频资源位于第一时频资源内的例子外，资源指示信道占用的第二时频资源的时频范围也可以不位于第一时频资源所占用的时频范围内，本发明实施例对此不作限定。
应理解，本发明实施例的资源指示信道指示的第一时频资源，也可以认为是该资源指示信道所辖时间范围和频率范围。一个资源指示信道所辖的频率范围的大小是频率栅格大小的整数倍N(N大于或等于1)，资源指示信道所辖的所辖时间范围是一个或多个固定时间单位或者可配置的时间长度(可在资源指示信道内指示)。系统可以约定，如果N大于1，则终端无需到该资源指示信道所辖的时间范围内的另外N-1个频率栅格上搜索其它的资源指示信道，从而可以提高基站和终端之间交互资源分配情况的效率。
应注意的是，本发明实施例中通过资源指示信道指示的第一时频资源R，优选地，可以包括一定时间范围和一定频率范围内的所有资源单元，即图2A和图2B所示的形状规则的一片区域；第一时频资源R也可以从一定时间范围和一定频率范围内的所有资源单元中扣除一些资源单元，即图2C所示的形状不规则的一片区域。此外，第二时频资源r可以位于第一时频资源R的边缘位置(如图2A至图2G所示)，也可以位于第一时频资源R的非边缘位置(如图2H所示)。
资源指示信道可以用于指示第一时频资源不被使用，即资源指示信道还可以用于指示资源不使用的区域，如图2I所示。例如，可以应用于小区间的干扰协调等场景。资源使用或不使用，可以通过在资源指示信道中设置指示位(bits)的取值来进行区分。
在本发明实施例中，至少一个资源指示信道对应的至少一个第一时频资 源可以构成小区。当小区中包括多个资源指示信道对应的多个第一时频资源时，多个第一时频资源对应的时间范围和/或频率范围不完全相同。例如，如图3所示，小区中包括3个资源指示信道对应的3个第一时频资源，分别包括第一时频资源S(对应资源指示信道s)、第一时频资源T(对应资源指示信道t)和第一时频资源U(对应资源指示信道u)。其中，第一时频资源S和第一时频资源T的时间范围不相同；第一时频资源S和第一时频资源U对应的频率范围不相同。由此，本发明实施例的方案可以突破现有技术中小区和/或载波占用固定连续带宽的限制，从而可以对时频资源进行更灵活地分配，提高无线通信系统的性能和适用性，实现资源的更优利用。
在本发明实施例中，通信参数可以包括小区标识(Identity，ID)，以标识资源指示信道对应的第一时频资源所属的小区。小区ID可以是一个32比特串，在本发明实施例中，一个资源指示信道中可以包括完整的小区ID，也可以包括部分小区ID(例如包括16比特)，小区ID的其它部分在其它的资源指示信道中传输，或者通过另外的专用信令或消息来发送。当然，本发明实施例中，小区ID也可以完全不通过资源指示信道传输，而是通过其它方式通知终端，本发明实施例对此不作限定。
在本发明实施例中，通信参数中可以包括第一时频资源使用的多址技术、第一时频资源使用的双工方式、第一时频资源使用的通信模式、第一时频资源使用的多址技术对应的基本物理层参数中的至少一种。
其中，第一时频资源使用的多址技术可以包括下列中的至少一种，例如，正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)技术、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)技术、简单频分多址FDMA技术、CDMA技术等。本发明实施例对时频资源的分配和指示的方案，能够允许系统中多种多址技术灵活并存。
当通信参数中包括第一时频资源使用的多址技术时，其还可以包括多址技术对应的基本物理层参数。在一个具体的例子中，第一时频资源使用OFDM技术，其基本物理层参数可以包括频域上子载波的间距、循环前缀(Cyclic Prefix，CP)长度，以及时域上的传输时间间隔(Transmission Time Interval，TTI)长度等。
第一时频资源使用的双工方式可以包括频分双工(Frequency Division  Duplexing，FDD)、半双工FDD、时分双工(Time Division Duplexing，TDD)、全双工等。
第一时频资源使用的通信模式可以包括基站到终端通信，或者终端到终端(Device-to-Device，D2D)通信等。
在本发明实施例中，资源指示信道的通信参数中还可以包括第一时频资源中所包括的控制信道信息。例如，该控制信道信息可以包括广播信道(Broadcast Channel，BCH)信息、主系统模块(Master Information Block，MIB)信息、寻呼信道(Paging Channel，PCH)、下行公共控制信道信息、下行专用控制信道信息、自包含模式信息、上行随机接入信道信息和上行控制信道信息中的至少一种。
其中，通信参数中可以包括第一时频资源中是否有BCH或MIB的信息，通常而言，在一个小区中至少有一个BCH或MIB，在小区的各个第一时频资源中，则可能有BCH或MIB，也可能没有BCH或MIB。
通信参数中可以包括第一时频资源中是否有PCH的信息。
通信参数中可以包括第一时频资源中是否有下行公共控制信道的信息，如果有下行公共控制信道，则通信参数中还可以包括第一个下行公共控制信道的时频位置，该时频位置可以由相对资源指示信道的偏移量指示。
通信参数中可以包括第一时频资源中是否有下行专用控制信道的信息，如果有下行专用控制信道，则通信参数中还可以包括第一个下行专用控制信道的时频位置，该时频位置可以由相对资源指示信道的偏移量指示。
对于TDD系统，通信参数中还可以包括第一时频资源是否为自包含模式的信息，自包含模式是指同时包含下行和上行，上行反馈同一时间范围内的下行传输。
通信参数中可以包括第一时频资源中是否有上行随机接入信道的信息，如果有上行随机接入信道，则通信参数中还可以包括随机接入信道的时频位置和数量，该时频位置可以由相对资源指示信道的偏移量指示。
通信参数中可以包括第一时频资源中是否有上行控制信道的信息，如果有上行控制信道，则通信参数中还可以包括上行控制信道的时频位置和数量，该时频位置可以由相对资源指示信道的偏移量指示。
应理解，本发明实施例的资源指示信道的内容并不仅限于以上列举出的内容，根据系统需要，资源指示信道中还可以包括与之相关的其它通信参数， 本发明实施例对其不作限定。
当第一时频资源所在的小区包括多个资源指示信道时，在小区的最后一个资源指示信道中可以包括用于指示该资源指示信道为该小区的最后一个资源指示信道的信息，以便于终端不再搜索资源指示信道，从而能够提高系统的性能和效率。指示该资源指示信道为该小区的最后一个资源指示信道可以通过显式的方式，例如设置一个标识位，根据标识位的取值区分是否最后一个资源指示信道。指示该资源指示信道为该小区的最后一个资源指示信道可以通过隐式的方式，例如在资源指示信道中使用特定的特征序列(例如与根序列相差特定数量的循环移位间隔的序列)来隐式的表征自身是最后一个资源指示信道，等等，本发明实施例对具体的实现方式不作限定。
当第一时频资源所在的小区包括多个资源指示信道时，在小区的非最后一个资源指示信道中可以包括用于指示该小区中下一个资源指示信道的时间范围和频率范围，以便于终端能够快速地搜索到下一个资源指示信道，从而能够提高系统的性能和效率。
应理解，这里的指示下一个资源指示信道的时间范围和频率范围，可以是隐式的指示，例如，可以是默认的形式，下一个资源指示信道默认在第一时频资源所之后的同一频率栅格的下一个时间单位上，但本发明实施例不限于此。指示下一个资源指示信道的时间范围和频率范围，也可以是显式的指示，尤其在资源指示信道所辖的第一时频资源不规则时，可以通过显式的指示方式，直接告知终端下一个资源指示信道的位置。
在S110基站生成资源指示信道后，S120，基站向终端发送资源指示信道。相应地，终端接收基站发送的资源指示信道。
在本发明实施例中，优选地，可以采用简单的单载波方式即非OFDM等多载波方式发送资源指示信道。并且，优选地，可以不使用多流多输入多输出(Multiple-Input Multiple-Output，MIMO)技术，而是使用对终端透明或者终端可以盲检测的多天线发射分集技术。本发明实施例对是否使用上述方式发送资源指示信道不作限定。另外，优选地，基站可以采用系统预设的调制方式对资源指示信道进行调制。终端可以按照预设的方式快速解调。基站还可以在资源指示信道中设置特征序列，该特征序列用于指示当前信道为资源指示信道，使终端快速准确的搜索到资源指示信道。
上述措施发送资源指示信道时使用较为基本的参数发送，可以降低终端 检测的复杂度，使终端快速准确的搜索到并解调资源指示信道，提高系统效率。
资源指示信道中包括的特征序列也可以用于时间和频率上的同步，或者可以表征(全部或部分)小区ID。通常，可以使用M序列或正交性(自相关、互相关性)好的其它序列。同一小区中的不同的资源指示信道可以使用同一个根(root)序列和/或通过把根序列循环移位等方式获取的同源序列。
本发明实施例中，在基站向终端发送资源指示信道之前，基站还可以为资源指示信道设置保护频带。对于资源指示信道位于总可用频带边缘的情况，带外辐射指标应符合所在地的监管要求。对于资源指示信道位于系统频带内部的情况，带外辐射指标应符合带内互干扰要求。
应理解，本发明实施例中，不同小区可以在时间或者频率上岔开资源指示信道的发射图样(pattern)，以避免相互干扰。在这种情况下，要求小区之间存在一定的时间协调关系。
