Description

调度方法、数据传输方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种调度方法、数据传输方法及装置。
背景技术
目前，在长期演进LTE系统中，用户设备UE在下行子帧检测下行控制信息DCI，DCI包含UE发送物理上行共享信道PUSCH的调度信息和UE接收物理下行共享信道PDSCH的调度信息，例如频域上使用的物理资源块的个数，使用的调制编码方式或者调制方式以及承载的传输块包含的比特数等。PUSCH信道主要承载的是终端发送的上行数据，采用单载波频分多址SC-FDMA的格式发送，在频率域上最小的调度粒度是1个物理资源块PRB，1个PRB在频率域上包含12个正交子载波，其中子载波之间的间隔是15kHz，因此，1个PRB包含180kHz的频率资源。
而随着通信技术的快速发展，已经出现了多种LTE的终端类型或者一类终端类型具有的能力可能有多种，比如，第一类终端，上行支持正交子载波间隔为3.75kHz的单个子载波SC-FDMA发送或子信道带宽为3.75kHz的单个子信道的FDMA发送；第二类终端或者第一类终端具有的能力为，上行支持正交子载波间隔为15kHz的单个子载波SC-FDMA发送；第三类终端或者第一类终端具有的能力为：上行支持正交子载波间隔为15kHz的多个子载波SC-FDMA的发送。这三类终端下行都支持正交频分多址OFDMA技术，且子载波间隔为15kHz。
然而，由于LTE系统最小的调度粒度是1个PRB，不支持单个子载波或者多个子载波粒度的调度，因此，这三类终端在现有LTE系统中都无法支持。比如，对于第一类终端，发送一个3.75kHz的单个子载波或子信道的信号，这个信号在时域上的长度至少是发送一个15kHz的单个子载波对应的信号的长度的4倍，而LTE系统的帧结构是按照15kHz子载 波间隔设计的，所以不支持第一类终端。因此，亟需一种调度方法、数据传输方法及装置。
发明内容
本发明的实施例提供一种调度方法、数据处理方法及装置，解决了现有LTE系统不支持新出现的三类终端的问题。
为达到上述目的，本发明的实施例采用如下技术方案：
第一方面，提供一种调度方法，应用于通信系统，所述方法包括：
基站向第一类终端发送下行控制信息DCI，所述DCI包含用于指示所述第一类终端使用第一模式帧格式发送上行数据时的调度信息；
其中，所述第一模式帧格式包括至少1个上行子帧，每个上行子帧包含至少1个第一模式帧格式符号；
所述第一模式帧格式符号的持续时间至少为第二模式帧格式符号持续时间的4倍，所述第二模式帧格式符号为LTE系统单载波频分多址SC-FDMA符号。
其中，当LTE系统上行配置为普通循环前缀CP时，每个上行子帧持续时间为1毫秒并包含14个SC-FDMA符号，因此所述LTE系统每个SC-FDMA符号包含普通循环前缀且平均持续时间为1/14毫秒，值得注意的是LTE系统中每个上行子帧包含的SC-FDMA符号的持续时间可能不同，例如每个上行子帧包含的14个SC-FDMA符号中，有2个长SC-FDMA符号且每个长SC-FDMA符号的持续时间为71.88微秒，有12个短SC-FDMA符号且每个短SC-FDMA符号的持续时间为71.35微秒；当LTE系统上行配置为扩展循环前缀CP时，每个上行子帧持续时间为1毫秒并包含12个SC-FDMA符号且每个SC-FDMA符号的持续时间相同，因此所述LTE系统每个SC-FDMA符号包含扩展循环前缀且持续时间为1/12毫秒。
当所述LTE系统SC-FDMA符号不包含CP时，每个符号的持续时间为66.7微秒。
所述上行数据承载在物理上行共享信道PUSCH上或者承载在为第一类终端定义的发送上行数据的物理信道。

例如，下行控制信息DCI包括用于指示终端发送上行数据的调度信息，其中至少包括在频域上使用的子载波的个数，使用的调制编码方式或者调制方式以及承载的传输块包含的比特数等中的一种。
需要说明的是，当上行采用单载波频分多址SC-FDMA时，第一模式帧格式符号可以是SC-FDMA符号；当上行采用FDMA频分多址时，第一模式帧格式符号可以是FDMA符号，本发明实施例对此不作具体限定。另外，第一模式帧格式符号可以是添加了循环前缀CP后的符号，也可以是未添加CP的符号；第二模式帧格式符号可以是添加了循环前缀CP后的符号，也可以未添加CP的符号。
由于该通信系统可以为频分双工(Frequency Division Duplex，FDD)系统，也可以为时分双工(Time Division Duplex，TDD)系统，因此，该第二模式帧格式包括适用于FDD系统的帧结构类型一，以及适用于TDD系统的帧结构类型二，且当该通信系统为FDD或者为TDD时，对应的第一模式帧格式是不相同的。
其中，第二模式帧格式包括的适用于FDD系统的帧结构类型一如图3所示，帧结构类型一中1个无线帧的时间长度为10毫秒，1个无线帧由20个时隙组成，每个时隙为0.5毫秒，两个时隙为1个子帧，也即是，帧结构类型一包括10个子帧，每个子帧的长度为1毫秒，且采用普通CP时，每个子帧包含14个OFDM符号或SC-FDMA符号，采用扩展CP时，每个子帧包含12个OFDM符号或者SC-FDMA符号。
第二模式帧格式包括的适用于TDD系统的帧结构类型二如图9所示， 第二模式帧格式包括1个10毫秒长的无线帧，由两个长度为5毫秒的半帧组成，每个半帧由5个1毫秒的子帧组成，其中包括下行子帧、特殊子帧和上行子帧，特殊子帧包括下行导频时隙DwPTS、上行导频时隙UpPTS和保护间隔GP，当下行转上行的切换点是以5毫秒为周期时，特殊子帧在两个半帧内都存在，当下行转上行的切换点是以10毫秒为周期时，特殊子帧仅在第一个半帧内存在，且采用普通CP时，每个子帧包含14个OFDM符号或SC-FDMA符号，采用扩展CP时，每个子帧包含12个OFDM符号或者SC-FDMA符号。

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。
在介绍本发明之前，首先对本发明中的用户终端类型和应用场景进行简单介绍。
本发明实施例中的用户终端类型主要包括现有LTE终端和新出现终端。其中，现有LTE终端，上行支持子载波间隔为15kHz的正交子载波SC-FDMA的发送，最小的调度粒度是1个PRB，包含12个正交子载波即180kHz，不支持单个子载波或者多个子载波粒度的调度。新出现终端主要包括三类，第一类终端，上行支持正交子载波间隔为3.75kHz的单个子载波SC-FDMA发送或子信道带宽为3.75kHz的单个子信道的FDMA发送；第二类终端，上行支持正交子载波间隔为15kHz的单个子载波SC-FDMA发送；第三类终端：上行支持正交子载波间隔为15kHz的多个子载波SC-FDMA的发送。当然，这三类终端也可以是一种终端，这一种终端具有其中一种或两种或同时具有上述三类终端的功能，且这三类终端的下行都支持正交频分多址OFDMA技术，且子载波间隔为15kHz。上述三类终端可能是三种不同的终端类型，也可能只是一种终端类型但具有其 中一种或两种或三种不同的终端能力，为方便叙述统称为三类终端，而在本发明中不对终端类型和终端能力作具体限定。另外，这三类终端主要用于物联网通信，因此支持这三类新出现终端的系统可以称为窄带物联网NBIOT系统。
本发明实施例中的应用场景根据使用的频率资源的不同，大致可以分为三种场景。其中，第一种场景，即独立部署场景，专用的频率资源组网支持新的三种终端，所用频率资源可以是位于从GSM系统中回收重新利用的频段，或者是位于3G系统或是LTE系统所用的频段资源。在独立部署场景中，系统中仅支持新的三种终端类型中的一种或多种，不存在其他类型的LTE终端。第二种场景，即保护带部署场景，系统所使用的频率资源位于LTE系统使用的频段的保护带内。第三种场景，即带内部署场景，所使用的频率资源位于LTE系统的一个标准载波，如10MHz或20MHz的带宽之内，即LTE系统的一个标准载波内同时支持普通LTE终端以及新的三种终端类型中的一种或多种，因此，为了不影响普通LTE终端的正常通信，第三种场景中NBIOT系统发送下行信道能使用的最大发送功率可能更小。
本发明的实施例所应用的通信系统的系统架构如图1所示，该系统架构图包括基站101、用户终端102、以及通信信道103。
其中，基站101具有共享信道的调度功能，具有基于发送到用户终端102的分组数据的历史来建立调度，调度就是在多个用户终端102共用传输资源时，需要有一种机制来有效地分配物理层资源，以获得统计复用增益。
用户终端102可以是多个用户终端，且用户终端102具有通过与基站101之间建立的通信信道103而发送和接收数据的功能。用户终端102根据通过调度控制信道发送的信息，进行共享信道的发送或接收处理。另外，用户终端102可以是移动台，手机、计算机以及便携终端等等，且该用户终端102的类型可以相同，也可以不同。
基站101与用户终端102之间通过通信信道103进行数据的接收和发送，该通信信道103可以是无线通信信道，且在无线通信信道中，至少存在共享信道和调度控制信道，共享信道是为了发送和接收分组而在多个用 户终端102之间公用，调度控制信道用于发送共享信道的分配、以及相应的调度结果等。
图2为本发明实施例提供的一种调度方法的流程示意图，应用于通信系统，参见图2，该方法包括以下几个步骤。
步骤201：基站向第一类终端发送下行控制信息DCI，DCI包含用于指示第一类终端使用第一模式帧格式发送上行数据时的调度信息。
其中，第一模式帧格式包括至少1个上行子帧，每个上行子帧包含至少1个第一模式帧格式符号；第一模式帧格式符号的持续时间至少为第二模式帧格式符号持续时间的4倍，第二模式帧格式符号为LTE系统单载波频分多址SC-FDMA符号。
需要说明的是，当上行采用单载波频分多址SC-FDMA时，第一模式帧格式符号可以是SC-FDMA符号；当上行采用FDMA频分多址时，第一模式帧格式符号可以是FDMA符号，本发明实施例对此不作具体限定。另外，第一模式帧格式符号可以是添加了循环前缀CP后的符号，也可以是未添加CP的符号；第二模式帧格式符号可以是添加了循环前缀CP后的符号，也可以未添加CP的符号。
其中，当LTE系统上行配置为普通循环前缀CP时，每个上行子帧持续时间为1毫秒并包含14个SC-FDMA符号，因此所述LTE系统每个SC-FDMA符号包含普通循环前缀且平均持续时间为1/14毫秒，值得注意的是LTE系统中每个上行子帧包含的SC-FDMA符号的持续时间可能不同，例如每个上行子帧包含的14个SC-FDMA符号中，有2个长SC-FDMA符号且每个长SC-FDMA符号的持续时间为71.88微秒，有12个短SC-FDMA符号且每个短SC-FDMA符号的持续时间为71.35微秒；当LTE系统上行配置为扩展循环前缀CP时，每个上行子帧持续时间为1毫秒并包含12个SC-FDMA符号且每个SC-FDMA符号的持续时间相同，因此所述LTE系统每个SC-FDMA符号包含扩展循环前缀且持续时间为1/12毫秒。当所述LTE系统SC-FDMA符号不包含CP时，每个符号的持续时间为66.7微秒。
上行数据可以承载在物理上行共享信道PUSCH上，或者承载在为第一类终端定义的发送上行数据的物理信道上。
由于该通信系统可以为频分双工(Frequency Division Duplex，FDD)系统，也可以为时分双工(Time Division Duplex，TDD)系统，因此，该第二模式帧格式包括适用于FDD系统的帧结构类型一，以及适用于TDD系统的帧结构类型二，且当该通信系统为FDD或者为TDD时，对应的第一模式帧格式是不相同的。
其中，第二模式帧格式包括的适用于FDD系统的帧结构类型一如图3所示，帧结构类型一中1个无线帧的时间长度为10毫秒，1个无线帧由20个时隙组成，每个时隙为0.5毫秒，两个时隙为1个子帧，也即是，帧结构类型一包括10个子帧，每个子帧的长度为1毫秒，且采用普通CP时，每个子帧包含14个OFDM符号或SC-FDMA符号，采用扩展CP时，每个子帧包含12个OFDM符号或者SC-FDMA符号。
另外，FDD系统下对应的第一模式帧格式如下所述。
具体的，如图4所示，当该通信系统为频分双工FDD，且上行采用普通循环前缀CP时，若上行子帧持续时间为1毫秒，上行子帧包含3个第一模式帧格式符号，且该3个第一模式帧格式符号的持续时间等于12个第二模式帧格式符号的持续时间且小于1毫秒，图中M1表示第一模式帧格式，M1中的数值0-2表示第一模式帧格式符号的编号，M2表示第二模式帧格式，M2中的数值0-6表示第二模式帧格式符号的编号，U表示上行子帧，第二模式帧格式符号的持续时间为每个SC-FDMA符号包含普通CP的持续时间。
如图5所示，当该通信系统为FDD，且上行采用扩展CP时，若上行子帧持续时间为1毫秒，上行子帧包含3个第一模式帧格式符号，且3个第一模式帧格式符号的持续时间等于12个第二模式帧格式符号的持续时间且等于1毫秒，第二模式帧格式符号的持续时间为每个SC-FDMA符号包含扩展CP的持续时间。
进一步的，当该通信系统为FDD，第一模式帧格式时间长度或第一模式帧格式中1个无线帧的时间长度为N*10毫秒，其中N为1或大于0的偶数，第一模式帧格式中的上行子帧为M毫秒，其中M为大于0的偶数，且M<＝N*10；
如图6所示，当第一模式帧格式中的上行子帧持续时间为2毫秒，且 通信系统为上行采用普通CP时，上行子帧包含7个第一模式帧格式符号，且该7个第一模式帧格式符号的持续时间等于28个第二模式帧格式符号的持续时间且等于2毫秒。也即是，当该通信系统为上行采用普通CP时，7个第一模式帧格式符号的持续时间等于28个第二模式帧格式符号的持续时间，第二模式帧格式符号的持续时间为每个SC-FDMA符号包含普通CP的持续时间。
如图7所示，当第一模式帧格式中的上行子帧持续时间为2毫秒，且通信系统为上行采用扩展CP时，上行子帧包含6个第一模式帧格式符号，且该6个第一模式帧格式符号的持续时间等于24个第二模式帧格式符号的持续时间且等于2毫秒。也即是，当该通信系统为上行采用扩展CP时，6个第一模式帧格式符号的持续时间等于24个第二模式帧格式符号的持续时间，第二模式帧格式符号的持续时间为每个SC-FDMA符号包含扩展CP的持续时间。
进一步的，在第一模式帧格式包括的至少1个上行子帧中的至少1个第一模式帧格式符号上发送上行解调参考信号，该上行解调参考信号用于帮助解调上行数据或上行控制信息。
也即是，当第一模式帧格式包括一个上行子帧，该上行子帧包括至少一个第一模式帧格式符号时，该上行解调参考信号可以在该至少一个第一模式帧格式符号中的一个或者多个第一模式帧格式符号上发送；当第一模式帧格式包括多个上行子帧，也即是包括两个或者两个以上的上行子帧时，可以在该多个上行子帧中任意一个或者多个内发送该上行解调参考信号，且在上行子帧包括的至少一个第一模式帧格式符号中的一个或者多个第一模式帧格式符号上发送。
比如，当第一模式帧格式包括一个上行子帧，该上行子帧包括3个第一模式帧格式符号时，该上行解调参考信号可以在3个第一模式帧格式符号中的任意一个或者两个第一模式帧格式符号上发送，也可以在3个第一模式帧格式符号都发送上行解调参考信号；当第一模式帧格式包括两个上行子帧，每个上行子帧包括3个第一模式帧格式符号时，可以在两个上行子帧中的任意一个内发送上行解调参考信号，也可以在两个上行子帧都发送上行解调参考信号，且该上行解调参考信号可以在两个上行子帧包括的 第一模式帧格式符号中的任意一个或者多个第一模式帧格式符号上发送，本发明实施例对此不作限定。
可选的，当1毫秒时间长度包含的第一模式帧格式符号中的最后一个第一模式帧格式符号与1毫秒时间长度内的最后一个第二模式帧格式符号有部分重叠或完全重叠时，1毫秒时间长度内的最后一个第一模式帧格式符号上不发送上行信号和信道，当第一模式帧格式符号为包含普通CP的符号时，第二模式帧格式符号为包含普通CP的SC-FDMA符号；当第一模式帧格式符号为包含扩展CP的符号时，第二模式帧格式符号为包含扩展CP的SC-FDMA符号；当第一模式帧格式符号为不包含CP的符号时，第二模式帧格式符号为不包含CP的SC-FDMA符号。
也即是，当第一模式帧格式符号的边界与第二模式帧格式符号的边界是对齐的时，若在第三种场景，即带内部署场景时，为了不影响现有LTE终端发送探测参考信号(Sounding Reference Signal，SRS)，在1毫秒时间长度包含的第一模式帧格式符号中的最后一个第一模式帧格式符号与1毫秒时间长度内的最后一个第二模式帧格式符号有部分重叠或完全重叠时，1毫秒时间长度内的最后一个第一模式帧格式符号上不发送上行信号和信道。可选地，对于第一种独立部署场景下和第二种保护带场景下，在1毫秒时间长度包含的第一模式帧格式符号中的最后一个第一模式帧格式符号与1毫秒时间长度内的最后一个第二模式帧格式符号有部分重叠或完全重叠时，1毫秒时间长度内的最后一个第一模式帧格式符号上不发送上行信号和信道。
比如，如图5所示的第一模式帧格式，若该3个第一模式帧格式符号分别为符号0、符号1、符号2，则符号2上不发送上行信号或信道；如图6所示的第一模式帧格式，若该7个第一模式帧格式符号分别为符号0、符号1、…、符号5、符号6，则在符号3和符号6上不发送上行信号或信道；如图7所示的第一模式帧格式，若该6个第一模式帧格式符号分别为符号0、符号1、…、符号4、符号5，则在符号2和符号5上不发送上行信号或信道。
进一步的，当第二模式帧格式包括不可用上行子帧时，在第二模式帧格式中不可用上行子帧的持续时间内对应的第一模式帧格式符号上不发 送上行信号和信道，所述不可用上行子帧为一个或多个上行子帧，每个上行子帧持续时间为1毫秒，所述不可用上行子帧是指在不可用上行子帧内的全部或部分频率资源为预留资源，所述预留资源用于特殊终端或者用于特殊通信系统支持的终端和基站或终端之间的通信，而对非特殊终端或非特殊通信系统支持的终端和基站或终端之间的通信外，不能使用预留的资源，例如LTE系统中不可用上行子帧中的全部或部分频率资源为预留资源并用于设备和设备之间这种特殊系统的通信，而在不可用上行子帧上普通LTE终端不能使用所述预留资源。
第一类终端通过接收系统信息获知不可用上行子帧的信息，包括哪些上行子帧为不可用上行子帧，或进一步包括哪些不可用上行子帧内哪些频域资源为预留资源等。
也即是，在第三种场景，即带内部署场景时，若第二模式帧格式包括不可用上行子帧，在与第二模式帧格式中不可用上行子帧的持续时间内对应的第一模式帧格式符号上不发送上行信号和信道，或者将本该在与第二模式帧格式中不可用上行子帧的持续时间对应的第一模式帧格式符号上上行信号或信道顺序推迟到下一个与第二模式帧格式中可用上行子帧的持续时间对应的第一模式帧格式符号上发送，所述可用上行子帧是指除第二模式帧格式中不可用上行子帧之外的上行子帧。
进一步的，该调度信息包含第一模式帧格式对应的物理资源信息，该物理资源信息包括时间资源和频率资源，时间资源包含至少一个上行子帧，频率资源包含一个子载波，且子载波间隔为3.75kHz。
其中，该调度信息包含的物理资源信息中的时间资源可以称为调度长度，最小的调度长度为3个第一模式帧格式符号的长度，实际的调度长度可以根据基站与终端之间的距离，或者根据终端在小区中所要求达到的覆盖要求，基站可以支持至少一个调度长度。比如，调度长度A1：连续NA1个上行子帧，小区中支持的最大覆盖为LA1，调度长度A2：连续NA2个上行子帧，小区中支持的最大覆盖为LA2等等，LA2的覆盖范围大于或等于比LA1的覆盖范围，NA1、NA2为正整数，NA2大于或等于NA1且可以事先设置，本发明实施例对此不作具体限定。另外，对于每种调度长度，该调度信息包含的物理资源信息中的频率资源可以为1个子载波或多 个子载波，包含的子载波的数量也可以事先设置，本发明实施例对此不作具体限定。

例如，下行控制信息DCI包括用于指示终端发送上行数据的调度信息，其中至少包括在频域上使用的子载波的个数，使用的调制编码方式或者调制方式以及承载的传输块包含的比特数等中的一种。

图8为本发明实施例提供的一种调度方法的流程示意图，应用于通信系统，该方法包括以下几个步骤。
步骤301：基站向第一类终端发送下行控制信息DCI，DCI包含用于指示第一类终端使用第一模式帧格式发送上行数据时的调度信息。
其中，第一模式帧格式包括至少一个上行子帧，每个上行子帧包含至少一个第一模式帧格式符号；第一模式帧格式符号的持续时间至少为第二 模式帧格式符号持续时间的4倍，第二模式帧格式符号为LTE系统SC-FDMA符号。
其中，当LTE系统上行配置为普通循环前缀CP时，每个上行子帧持续时间为1毫秒并包含14个SC-FDMA符号，因此所述LTE系统每个SC-FDMA符号包含普通循环前缀且平均持续时间为1/14毫秒，值得注意的是LTE系统中每个上行子帧包含的SC-FDMA符号的持续时间可能不同，例如每个上行子帧包含的14个SC-FDMA符号中，有2个长SC-FDMA符号且每个长SC-FDMA符号的持续时间为71.88微秒，有12个短SC-FDMA符号且每个短SC-FDMA符号的持续时间为71.35微秒；当LTE系统上行配置为扩展循环前缀CP时，每个上行子帧持续时间为1毫秒并包含12个SC-FDMA符号且每个SC-FDMA符号的持续时间相同，因此所述LTE系统每个SC-FDMA符号包含扩展循环前缀且持续时间为1/12毫秒。当所述LTE系统SC-FDMA符号不包含CP时，每个符号的持续时间为66.7微秒。
另外，上行数据可以承载在物理上行共享信道PUSCH上，或者承载在为第一类终端定义的发送上行数据的物理信道上。
需要说明的是，当上行采用SC-FDMA时，第一模式帧格式符号可以是SC-FDMA符号；当上行采用FDMA频分多址时，第一模式帧格式符号可以是FDMA符号，本发明实施例对此不作具体限定。另外，第一模式帧格式符号可以是添加了循环前缀CP后的符号，也可以是未添加CP的符号；第二模式帧格式符号可以是添加了循环前缀CP后的符号，也可以未添加CP的符号。
由于该通信系统可以为频分双工FDD系统，也可以为时分双工TDD系统，因此，该第二模式帧格式包括适用于FDD系统的帧结构类型一，以及适用于TDD系统的帧结构类型二，且当该通信系统为FDD或者为TDD时，对应的第一模式帧格式是不相同的。
其中，第二模式帧格式包括的适用于TDD系统的帧结构类型二如图9所示，第二模式帧格式包括1个10毫秒长的无线帧，由两个长度为5毫秒的半帧组成，每个半帧由5个1毫秒的子帧组成，其中包括下行子帧、特殊子帧和上行子帧，特殊子帧包括下行导频时隙DwPTS、上行导频时 隙UpPTS和保护间隔GP，当下行转上行的切换点是以5毫秒为周期时，特殊子帧在两个半帧内都存在，当下行转上行的切换点是以10毫秒为周期时，特殊子帧仅在第一个半帧内存在，且采用普通CP时，每个子帧包含14个OFDM符号或SC-FDMA符号，采用扩展CP时，每个子帧包含12个OFDM符号或者SC-FDMA符号。
另外，TDD系统下对应的第一模式帧格式如下所述。
具体的，当该通信系统为时分双工TDD时，第一模式帧格式除了包括至少1个上行子帧，还包括至少1个特殊子帧和至少1个下行子帧，特殊子帧包含下行导频时隙DwPTS、上行导频时隙UpPTS和保护间隔GP中的至少一个。
当通信系统为TDD时，第二模式帧格式为帧结构类型二，第二模式帧格式中上下行配置如下表1所示，其中D为下行子帧，S为特殊子帧，U为上行子帧。其中每个子帧的持续时间为1毫秒，特殊子帧包括下行导频时隙DwPTS、上行导频时隙UpPTS和保护间隔GP，当第一模式帧格式包括UpPTS，且第一模式帧格式中UpPTS的长度小于等于第二类型帧格式中UpPTS的长度时，在第一模式帧格式包括的UpPTS不发送上行信号和信道，其中第二模式帧格式中特殊子帧中DwPTS/GP/UpPTS的长度如下表2所示。

也即是，在第三种场景，即带内部署场景时，若第二模式帧格式包括不可用上行子帧，在与第二模式帧格式中不可用上行子帧的持续时间对应的第一模式帧格式符号上不发送上行信号和信道，或者将本该在与第二模式帧格式中不可用上行子帧的持续时间对应的第一模式帧格式符号上上行信号或信道顺序推迟到下一个与第二模式帧格式中可用上行子帧的持续时间对应的第一模式帧格式符号上发送。
可选的，在至少一个上行子帧中的至少一个第一模式帧格式符号上发送上行解调参考信号。
也即是，当第一模式帧格式包括一个上行子帧，该上行子帧包括至少一个第一模式帧格式符号时，该上行解调参考信号可以在该至少一个第一模式帧格式符号中的一个或者多个上发送；当第一模式帧格式包括多个上行子帧，也即是包括两个或者两个以上的上行子帧时，可以在该多个上行子帧中任意一个或者多个内发送上行解调参考信号，且在上行子帧包括的至少一个第一模式帧格式符号中的任意一个或者多个上发送。
比如，当第一模式帧格式包括一个下行子帧，一个特殊子帧和一个上行子帧，且该上行子帧包括3个第一模式帧格式符号时，该上行解调参考信号可以在3个第一模式帧格式符号中的任意一个或者任一两个上发送，也可以在3个第一模式帧格式符号都发送上行解调参考信号；当第一模式帧格式包括一个下行子帧，一个特殊子帧和两个上行子帧，且每个上行子帧包括3个第一模式帧格式符号时，可以在两个上行子帧中的任意一个内 发送上行解调参考信号，也可以两个上行子帧内都发送上行解调参考信号，且该上行解调参考信号可以在两个上行子帧包括的第一模式帧格式符号中的任意一个或者多个上发送，本发明实施例对此不作限定。
进一步的，该调度信息包含第一模式帧格式对应的物理资源信息，该物理资源信息包括时间资源和频率资源，时间资源包含至少一个上行子帧，频率资源包含一个子载波。
其中，该调度信息包含的物理资源信息中的时间资源可以称为调度长度，最小的调度长度为3个第一模式帧格式符号的长度，实际的调度长度可以根据基站与终端之间的距离，或者根据终端在小区中所要求达到的覆盖的要求，基站可以支持至少一个调度长度。比如，调度长度C1：连续NC1个上行子帧，小区中支持的最大覆盖为LC1，调度长度C2：连续NC2，小区中支持的最大覆盖为LC2个上行子帧等等，LC2的覆盖范围大于或等于比LC1的覆盖范围，NC1、NC2为正整数，NC2大于或等于NC1且可以事先设置，本发明实施例对此不作具体限定。另外，对于每种调度长度，该调度信息包含的物理资源信息中的频率资源为1个子载波。
步骤302：基站向第二类终端或者第三类终端发送下行控制信息DCI，该DCI包含用于指示第二类终端或者第三类终端发送上行数据使用第二模式帧格式时的调度信息。
其中，第二模式帧格式包括适用于FDD系统的帧结构类型一，以及适用于TDD系统的帧结构类型二，当该通信系统为TDD时，第二模式帧格式是指适用于TDD系统的帧结构类型二，帧结构类型二包括1个10毫秒长的无线帧，由两个长度为5毫秒的半帧组成，每个半帧由5个1毫秒的子帧组成，其中包括下行子帧、特殊子帧和上行子帧，特殊子帧包括下行导频时隙DwPTS、上行导频时隙UpPTS和保护间隔GP，也即是，第二模式帧格式包括10个子帧，每个子帧的长度为1毫秒，且第二模式帧格式对应的物理资源信息中子载波之间的间隔为15kHz。
例如，下行控制信息DCI包括用于指示终端发送上行数据的调度信息，其中至少包括在频域上使用的子载波的个数，使用的调制编码方式或者调制方式以及承载的传输块包含的比特数等中的一种。
需要说明的是，通信系统为TDD系统时，具体的第二模式帧格式可 以参考相关技术，本发明实施例在此不再赘述。
步骤303：终端接收基站发送的下行控制信息DCI，并基于下行控制信息发送上行数据。
具体的，当该终端为第一类终端时，该DCI包含用于指示第一类终端发送上行数据使用第一模式帧格式时的调度信息，第一类终端在接收到DCI后向基站发送第一模式帧格式的上行数据；当该终端为第二类终端或者第三类终端时，该DCI包含用于指示第二类终端或者第三类终端发送上行数据使用第二模式帧格式时的调度信息，第二类终端或者第三类终端在接收到调度信息后，向基站发送第二模式帧格式的上行数据。
需要说明的是当终端为第二类终端或者第三类终端时，该调度信息包含第二模式帧格式对应的物理资源信息，该物理资源信息包括时间资源和频率资源，时间资源包含至少一个上行子帧，频率资源包含一个子载波，且子载波之间的间隔为15kHz。
其中，该调度信息包含的物理资源信息中的时间资源可以称为调度长度，最小的调度长度为1个第二模式帧格式中一个上行子帧的长度，实际的调度长度可以根据基站与终端之间的距离，或者根据终端在小区中所要求达到的覆盖要求，基站可以支持至少一个调度长度。比如，调度长度D1：连续ND1个上行子帧，小区中支持的最大覆盖为LD1，调度长度D2：连续ND2个上行子帧，小区中支持的最大覆盖为LD2等等，LD2的覆盖范围大于或等于比LD1的覆盖范围，ND1、ND2为正整数，ND2大于或等于ND1且可以事先设置，本发明实施例对此不作具体限定。另外，对于每种调度长度，当终端为第二类终端时，该调度信息包含的物理资源信息中的频率资源为1个子载波；当终端为第三类终端时，该调度信息包含的物理资源信息中的频率资源至少为1个子载波，且最多为12个子载波。
可选的，在步骤303之后，该方法还包括：
步骤304：终端向基站发送上行控制信息或者随机接入信息。
具体的，当该终端为第一类终端，该上行控制信息或者随机接入信息使用的帧格式为第一模式帧格式。其中，第一模式帧格式包括至少1个上行子帧，每个上行子帧包含至少1个第一模式帧格式符号；第一模式帧格 式符号的持续时间至少为第二模式帧格式符号持续时间的4倍，第二模式帧格式符号为LTE系统单载波频分多址SC-FDMA符号。
需要说明的是，该上行控制信息UCI包括ACK或NACK用于确认终端是否正确接收下行共享信道PDSCH上承载的下行数据；或者包含用于反应下行信道质量的信道状态信息CSI。该上行控制信息承载在物理上行控制信道PUCCH上，或者承载在为第一类终端定义的发送上行控制信息的物理信道上。该随机接入信息包括随机接入前导码，承载在物理随机接入信道PRACH上，或者承载在为第一类终端定义的发送上行随机接入信息的物理信道上。
当该终端为第二类终端或者第三类终端时，该上行控制信息或者随机接入信息使用的帧格式为第二模式帧格式，第二模式帧格式包括适用于FDD系统的帧结构类型一，以及适用于TDD系统的帧结构类型二，第二模式帧格式包含10个子帧，每个子帧的长度为1毫秒，且第二模式帧格式对应的物理资源信息中的子载波间隔为15kHz。
需要说明的是，当终端向基站发送上行控制信息或者随机接入信息时，终端发送的上行控制信息或者随机接入信息的帧格式可以为第一模式帧格式或者第二模式帧格式，且该第一模式帧格式和第二模式帧格式不仅可以从基站发送的下行控制信息DCI中获取，也可以预先进行设置，且在设置之后，第一类终端可以直接使用第一模式帧格式发送上行控制信息或随机接入信息，第二类终端或第三类终端也可以直接使用第二模式帧格式发送上行控制信息或随机接入信息，本发明实施例对此不作限定。
比如，第一模式帧格式为预先设置，即通信系统使用的特定的一种或几种载波频率对应使用第一模式帧格式，或者特定的下行同步信号序列或者特定的发送下行同步信号的格式即映射的具体时间和/或频率资源位置对应使用第一模式帧格式，或者下行系统信息包含或者特定的发送下行系统信息的格式即映射的具体时间和/或频率资源位置对应使用第一模式帧格式，终端根据上述特定对应关系或下行系统信息的指示信息获知使用第一模式帧格式后，可以直接向基站发送使用第一帧格式的上行控制信息或者随机接入信息。
