具体实施方式
为了使本发明的具体技术方案、发明目的更加清楚，下面结合具体的实施方式和附图作进一步清楚、完整地描述，显然，所描述的实施方式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作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。
本发明实施例提供的技术方案可以应用于各种无线通信网络，例如码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)和其它网络等。术语“网络”和“系统”可以相互替换。CDMA网络可以实现例如通用无线陆地接入(universal terrestrial radio access，UTRA)，CDMA2000等无线技术。UTRA可以包括CDMA(WCDMA)和其他CDMA的变形。CDMA2000可以覆盖临时标准(interim standard，IS)2000(IS-2000)，IS-95和IS-856标准。TDMA网络可以实现例如全球移动通信系统(global system for mobile communication，GSM)等无线技术。OFDMA网络可以实现诸如演进通用无线陆地接入(evolved UTRA，E-UTRA)、超级移动宽带(ultra mobile broadband， UMB)、IEEE 802.11(Wi-Fi)，IEEE 802.16(WiMAX)，IEEE 802.20，Flash OFDMA等无线技术。UTRA和E-UTRA是UMTS以及UMTS演进版本。3GPP在长期演进(long term evolution，LTE)和LTE高级(LTE Advanced，LTE-A)是使用E-UTRA的UMTS的新版本。UTRA、E-UTRA、UMTS、LTE、LTE-A和GSM在3GPP标准组织的文档中有记载描述。CDMA2000和UMB在3GPP2标准组织的文档中有记载描述。本发明实施例描述的技术也可以应用到上面所述的无线网络和无线技术中。
在本发明实施例中，将标准规定的非专用于MTC应用的帧结构称之为标准帧结构，或正常帧结构。标准帧结构所包含的子帧称为标准子帧，或正常子帧。例如，使用为现有通信标准协议中规定的帧结构及其规定的子帧，如3GPP GSM协议、UMTS协议或LTE协议，或者，3GPP2CDMA协议，或者，IEEE协议规定的帧结构实现语音或数据业务。通常，标准中规定的标准帧结构可以满足用户的语音和数据等业务需求，包括时延要求，在终端正常接入和实现业务的过程中，用户对于时延的要求不是非常高，根据标准帧结构以及标准子帧进行通信所产生的标准时延(或者，称为正常时延)，即使未达到毫秒级别，在不影响正常使用的情况下，用户都可以接受。但是，所述标准时延对于时延要求更高的一些MTC应用中则无法适用。
例如，在LTE系统中，标准帧结构中，无线帧的长度为10毫秒，该无线帧包含10个标准子帧，每个标准子帧长度为1毫秒(millisecond，ms)，标准子帧中包含12个或者14个符号。若UE需要发送上行数据，则UE在一个标准子帧中发送SR给基站，基站对于所述SR需要3ms进行解调获取所述SR中的信息，然后，基站在一个标准子帧中发送调度授权(scheduling grant，SG)给UE，所 述UE需要3ms来解调所述SG以获取所述SG中的信息，然后根据所述SG分配的信息来发送上行数据，若在一个标准子帧中发送上行数据，则所述UE在使用标准子帧进行上行数据发送过程中，所需要的标准时延至少为9ms。而对于一些时延要求高的MTC应用，例如智能电网中的时延要求为3ms，标准子帧无法满足低时延的需求。
如图1所示，本发明实施例提供了一种通信系统10，该通信系统10可以包括基站110和终端(terminal)120，所述终端120可以使用MTC子帧实现MTC业务。在本发明实施例中，所述MTC业务具有短时延的要求，所述短时延比所述标准时延更短。所述MTC业务仅是一种具有短时延需求业务的一种名称表示，可以包括任何短时延业务，MTC业务本身不对业务具有任何限制。所述MTC子帧仅是指一种子帧的名称的限定，本身不对具体的应用场景进行限定，可以适用于一切具有短时延要求的数据传输，因此，所述MTC业务也可以称为短时延业务，所述MTC子帧也可以称为短子帧。
在本发明实施例中，所述MTC子帧包含的符号的数量小于标准子帧包含的符号的数量，所述MTC子帧包含的符号的数量可以根据MTC业务要求的传输时延进行配置，可选地，还可以根据所述要求的传输时延，并结合调度时延和处理时延中的至少一种对MTC子帧包含的符号的数量进行配置。所述MTC子帧中包含的符号数量可以和所述要求的传输时延成正比，所述要求的传输时延越短，所述符号的数量越少。例如，在LTE系统中，一个标准子帧的长度为1ms，包含的符号的数量为12或14个，因此，本发明实施例中所述MTC子帧包含的符号数量可以小于14或12个，例如可以为2个或3个，或者根据需要可以配置为1个或其它小于12的数量，等等。在本发明实施例中，可以满足不同时延需求的MTC应用。
在本实施例中，所述终端120可以支持短时延业务，也可以称为支持短时延业务的终端，或者称为MTC终端。所述终端120也可以使用标准子帧进行数据传输，因此，所述终端120可以兼容实现标准时延或时延更长的数据传输业务。
在本发明实施例中，所述终端120可以为移动台(mobile station)、用户设备(user equipment)、用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台等。或者，所述终端120也可以包括用于机器与机器之间进行通信的终端设备，以及具有无线通信功能的物联网终端，例如相量测量单元(phasor measurement unit，简称PMU)、先进测量装置(advanced meter infrastructure，简称AMI)等。
本发明实施例中的所述基站110可以为宏基站，也可以为小基站等接入网设备。所述小基站的发射功率和覆盖范围都小于所述宏基站，例如，小基站可以为家庭型演进基站(home evolved NodeB，简称HeNodeB)，微型基站(micro base station)，接入点(access point，AP)，微微基站(pico base station)等。
如图1所述，可选地，所述通信系统10还可以包括不支持MTC业务的终端130，所述不支持短时延业务的终端130可以称为非MTC终端，所述非MTC终端可以使用标准子帧进行通信，因此，也可以称为标准终端或者传统终端。本发明实施例中，所述基站110可以使用MTC子帧和MTC终端120进行通信，同时还可以使用标准子帧和不支持MTC业务的非MTC终端130进行通信。可选地，所述基 站110在使用MTC子帧和支持短时延业务的终端120进行通信，和使用标准子帧和不支持段时延业务的终端130进行通信时，可以使用同一频带。
如图1所示，所述通信系统10也可以包括基站140，所述基站110和基站140可以都为宏基站，或者都为小基站，或者，一个是宏基站，另一个是小基站。所述基站140也可以使用MTC子帧和MTC终端120进行通信，同时还可以使用标准子帧和非MTC终端130进行通信。所述通信系统10还可以包括集中控制节点150，例如单一接入网控制器(single RAN controller，SRC)等等。所述基站110和基站140都可以通过所述集中控制节点进行控制。

所述基站110可以以所述MTC子帧为传输周期，在所述下行MTC资源的物理下行控制信道(physical downlink control channel，PDCCH)中发送所述MTC业务的下行控制信息给所述MTC终端。在本发明实施例中，所述MTC子帧为传输周期发送是指在MTC子帧为单位发送，也即在MTC子帧中，在相应的频率资源上发送信息。如图5所示，所述基站110可以在一个包含2个符号的MTC子帧中，在所述下行MTC资源的PDCCH中发送所述MTC业务的下行控制信息给所述终端120。所述用于传输所述MTC业务的下行数据的资源例如可以为所述下行MTC资源的物理下行共享信道(physical downlink shared channel，PDSCH)，或者是任何发送下行数据的信道资源。所述用于传输MTC业务的上行数据的资源例如可以为所述上行MTC资源的物理上行共享信道(physical uplink shared channel，PUSCH)，或者是任何发送上行数据的信道资源。
所述基站110也可以在所述标准子帧的PDCCH中发送所述MTC业务的下行控制信息给所述MTC终端。
若在步骤401和402中，所述基站110没有在所述MTC业务的资源配置信息中将所述MTC子帧中包含的符号数量发送给所述终端120，则所述下行控制信息可以包含所述MTC子帧中包含的符号的 数量。

在图4或图4B所提供的实施例中，当所述基站110为宏基站时，所述基站110覆盖的范围内，可以布置至少一个射频拉远单元(radio remote unit，RRU)，如图11所示，所述基站110使用MTC子帧和所述终端120进行通信，可以是在所述RRU的覆盖范围内，使用MTC子帧和所述终端120进行通信，在所述RRU的覆盖范围内，还可以使用标准子帧和所述非MTC终端130进行通信。在所述RRU覆盖范围内，当所述基站110使用MTC子帧和所述终端120使用特定频率资源进行通信时，所述基站110在所述MTC子帧的时间段内 不使用所述特定频率资源和所述非MTC终端130进行通信。在所述非RRU覆盖范围内，所述基站110可以使用标准子帧和所述非MTC终端130进行通信，所使用的频率资源和所述RRU覆盖范围内MTC子帧和所述终端120使用特定频率资源不同。当有多个RRU时，在不同RRU的覆盖范围中，所述基站110可以使用相同的频率资源分别和不同的MTC终端120进行通信，实现MTC业务。
在图4或图4B所提供的实施例中，所述基站110在发送所述MTC业务的资源配置信息时，可以使用第一载波，所述终端120在所述第一载波上接收所述基站110发送的所述MTC业务的资源配置信息。所述用于MTC业务的下行资源在第二载波上，所述用于MTC业务的上行资源在第三载波上，所述第一载波、第二载波和第三载波的频率互不相同。如图12所示，所述基站110可以使用所述第二载波在下行MTC资源中，以MTC子帧为传输周期向所述终端120发送所述MTC业务的下行数据。所述终端120可以使用所述第三载波，在上行MTC资源中，根据以所述MTC子帧为传输周期发送所述MTC业务的上行数据。
在本发明的实施例中，如图8、9、10、11或12中所示，在MTC子帧中，占用了标准子帧所占频率资源的全部频率资源。图8至图12作为本发明的一种实施例，并不限于本身所示，譬如，所示的MTC子帧的频率资源也可以占用标准子帧所占频率资源的部分频率资源。
在本发明实施例中，在配置了上行MTC资源和/或下行MTC资源后，还可以对所述配置的上行MTC资源和/或下行MTC资源进行重配置。基站可以通过在PDCCH，或者ePHCCH发送资源重配置信息给终端120，或者，也可以通过广播信息、RRC信令或者MAC信令发送资源重配置信息给终端120。
资源重配置信息可以用于为终端120配置用于MTC子帧传输的专用资源，或者可以配置用于MTC子帧传输的公共资源。在重配置用于MTC子帧传输的专用资源中，终端120可以根据收到的资源重配置信息，找到基站分配的上行MTC子帧的资源，并可以根据该上行MTC子帧的资源进行通信；和/或，根据收到的资源重配置信息，找到基站发送的下行MTC子帧，进而接收并解调资源。在重配置用于MTC子帧传输的公共资源中，终端120可以根据资源重配置信息指示的MTC子帧资源替换之前配置的MTC子帧资源，解调MTC子帧的PDCCH，确定分配的上行MTC子帧资源，从而使用上行MTC子帧的资源进行通信；和/或，使用资源重配置信息指示的MTC子帧资源替换之前配置的MTC子帧资源，找到用于下行MTC子帧的资源，然后，在用于下行MTC子帧的资源上解析MTC子帧的PDCCH信道，从而找到基站发送的下行MTC子帧。
在本发明实施例中，在配置了上行MTC资源和/或下行MTC资源后，或者在对所述配置的上行MTC资源和/或下行MTC资源进行重配置后，还可以删除所述配置的或重配置的上行MTC资源和/或下行MTC资源。可以发送资源删除信息给终端120，例如，可以通过在PDCCH，或者ePHCCH发送资源删除信息给终端120，或者，也可以通过广播信息、RRC信令或者MAC信令发送资源删除信息给终端120。所述资源删除信息可以用于指示删除之前配置的或重配置的全部MTC子帧资源，或者，也可以用于指示删除指定的特定部分资源。终端120在接收到资源删除信息后，根据资源删除信息的指示删除相应的MTC子帧资源。
