Description

传输数据的方法和装置 技术领域
本发明涉及通信领域，尤其涉及一种传输数据的方法和装置。
背景技术
在基于正交频分复用(Orthgonal Frenquency Divide Multiple access，OFDM)的无线蜂窝通信系统时分双工(Time Divide Duplex，TDD)制式下，基站通常在数据调度区调度上行/下行数据，在控制信息调度区调度上行/下行控制信息，可能会造成控制信息调度区资源浪费，数据传输效率低的问题。

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的一部分实施例，而不是全部实施例。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的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
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，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统或未来的5G系统等。
特别地，本发明实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，简称为“SCMA”)系统、低密度签名(Low Density Signature，简称为“LDS”)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本发明实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，简称为“OFDM”)、滤波器组多载波(Filter Bank Multi-Carrier，简称为“FBMC”)、通用频分复用(Generalized Frequency Division Multiplexing，简称为“GFDM”)、滤波正交频分复用(Filtered-OFDM，简称为“F-OFDM”)系统等。
还应理解，在本发明实施例中，终端设备可以经无线接入网(Radio Access Network，简称为“RAN”)与一个或多个核心网进行通信，该终端设备可称为接入终端、用户设备(User Equipment，简称为“UE”)、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、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，简称为“SIP”)电话、无线本地环路(Wireless Local Loop，简称为“WLL”)站、个人数字处理(Personal Digital Assistant，简称为“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、可穿戴设备以及未来5G网络中的终端设备。
还应理解，在本发明实施例中，网络设备可用于与终端设备通信，该网络设备可以是全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统或码分多址(Code Division Multiple Access，简称为“CDMA”)中的基站(Base Transceiver Station，简称为“BTS”)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统中的基站(NodeB，简称为“NB”)，还可以是长期演进(Long Term Evolution，简称为“LTE”)系统中的演进型基站(Evolutional Node B，简称为“eNB”或“eNodeB”)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G(5th-Generation)网络中的基站设备等。
图1示出了应用本发明实施例的一种通信系统的示意性构架图。如图1所示，该通信系统100可以包括网络设备102，该网络设备102可以包括一个或多个天线组，每个天线组可以包括一个或多个天线。例如，一个天线组可以包括天线104和106，另一个天线组可以包括天线108和110，附加组可以包括天线112和114。虽然图1中对于每个天线组示出了2个天线，但应理解每个天线组可以具有更多的或更少的天线。网络设备102可以附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而，可以理解，网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上进行通信的任意其它适合设备。
如图1所示，终端设备116与天线112和114通信，其中天线112和114通过前向链路118向终端设备116发送信息，并通过反向链路120从终端设备116接收信息。此外，终端设备122与天线104和106通信，其中天线104和106通过前向链路124向终端设备122发送信息，并通过反向链路126从终端设备122接收信息。
例如，在频分双工(Frequency Division Duplex，简称为“FDD”)系统中，前向链路118可利用与反向链路120不同的频带，前向链路124可利用与反向链路126不同的频带；再例如，在时分双工(Time Division Duplex，简称为“TDD”)系统和全双工(Full Duplex)系统中，前向链路118和反向链路120可以使用共同的频带，前向链路124和反向链路126也可以使用共同的频带。
被设计用于通信的每组天线和/或区域称为网络设备102的扇区。例如，可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中，网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外，与网络设备通过单个天线向它所有的终端设备发送信号的方式相比，在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时，相邻小区中的移动设备会受到较少的干扰。
在给定时间，网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时，无线通信发送装置可对数据进行编码以用于传输。具体地，无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中，传输块可被分段以产生多个码块。
图1示出了应用本发明实施例的一种通信系统，下面将结合图2，简述OFDM系统的原理和基本模型。
正交频分复用OFDM是一种多载波调制方式，通过减小和消除码间串扰的影响来克服信道的频率选择性衰落。它的基本原理是将信号分割为N个子信号，然后用N个子信号分别调制N个相互正交的子载波。由于子载波的频谱相互重叠，因而可以得到较高的频谱资源，近几年OFDM在无线通信领域得到了广泛的应用。
图2示出了OFDM基带信号处理原理图。其中，图2中(a)是发射机工作原理图，(b)是接收机工作原理图。在发射端，首先对比特流进行正交振幅调制(Quadrature Amplitude Modulation，QAM)或正交相移键控(Quadrature Phase Shift Keyin，QPSK)调制，然后依次经过串并变换和快速傅立叶反变换(Inverse Fast Fourier Transform，IFFT)，再将并行数据转化为串行数据，加上 保护间隔(又称“循环前缀”)，形成OFDM码元。在组帧时，须加入同步序列和信道估计序列，以便接收端进行突发检测、同步和信道估计，最后输出正交的基带信号。当接收机检测到信号到达时，首先进行同步和信道估计。当完成时间同步、小数倍频偏估计和纠正后，经过快速傅立叶变换(Fast Fourier Transform，FFT)，进行整数倍频偏估计和纠正，此时得到的数据是QAM或QPSK的已调数据。对该数据进行相应的解调，就可得到比特流。
图3示出了基于OFDM的无线蜂窝通信系统TDD制式下的一种帧结构，Self contain帧结构的两种子帧类型：Self contain subframe type 1(下行子帧)、以及Self contain subframe type 2(上行子帧)。如图3所示，下行子帧包含如下几部分内容：
下行控制信道：主要用于传输下行控制信息(Downlink Control Information，DCI)、以及物理混合自动重传指示信道(Physical Hybird Automatic Repeat Request Indicator Channel)的确认反馈信息(Acknowledgement，ACK)。
物理下行共享信道(Physical Downlink Shared Channel，PDSCH)：主要用于传输下行数据。
间隙GAP部分：主要用于预留上下行数传切换的时间。
上行控制信道：主要用于传输上行控制信息(Uplink Control Information，UCI)、以及探测用参考信号(Sounding Reference Signal，SRS)。
上行子帧包含如下几部分内容：
下行控制信道：主要用于传输DCI、以及PHICH ACK。其占用的符号个数可以和下行子帧中的下行控制信道一样。
间隙GAP部分：主要用于预留上下行数传切换的时间。
物理上行共享信道(Physical Uplink Shared Channel，PUSCH)：主要用于传输上行数据。
上行控制信道：主要用于传输UCI以及SRS。其占用的符号个数可以和下行子帧中的上行控制信道一样。
通常而言，下行控制信道、上行控制信道占用的OFDM符号个数是可配置的参数。例如，LTE系统的TDD制式下，物理下行控制信道(Physical Downlink Control Channel，PDCCH)通常采用子帧的前1～3个OFDM符号传 输下行控制信息。如果配置的符号个数太少，当系统内存在较多的UE时，可能会遇到控制信令不够用的问题；如果配置的符号个数太多，当系统内存在较少的UE时，就会遇到控制信道资源浪费的问题，这会降低增强移动宽带(enhanced Mobile Broad Band，eMBB)业务的数传效率。
应理解，该通信系统为无线蜂窝通信系统，例如该系统是基于正交频分复用技术，该网络设备例如为基站，该终端设备例如为用户设备。应理解，本发明实施例仅以采用OFDM技术的通信系统、基站和用户设备为例进行说明，但本发明实施例并不限于此。
上文中结合图1至图3描述了本发明实施例的应用场景以及基于OFDM的TDD制式下的一种帧结构，下面将结合图4至图6，从网络侧描述根据本发明实施例的传输数据的方法。
图4示出了根据本发明实施例的传输数据的方法200，该方法200例如可以由网络设备执行，该网络设备例如为基站。如图4所示，该方法200包括：
S210，确定第一传输时间间隔内是否有待调度的用户设备，该第一传输时间间隔采用的帧结构包括数据调度区和控制信息调度区，该控制信息调度区包括上行控制信息调度区和下行控制信息调度区，该数据调度区用于承载数据，该上行控制信息调度区用于承载上行控制信息，该下行控制信息调度区用于承载下行控制信息；
S220，当确定该第一传输时间间隔内有待调度的用户设备时，确定该控制信息调度区是否还有空余资源；
S230，在确定该控制信息调度区还有空余资源后，向该待调度的用户设备发送指示信息，该指示信息用于指示该用户设备在该上行控制信息调度区的空余资源发送上行数据和/或在该下行控制信息调度区的空余资源获取下行数据。
具体地，在本发明实施例中，网络设备负责管理上行和下行链路信道的资源调度，即系统资源分配过程，决定着什么时候、哪些资源可用于用户设备传输数据、或者接收数据。当网络设备确定在一个传输时间间隔(Transmission Time Interval，TTI)内有待调度的用户设备，网络设备可以判断控制信息调度区是否还有空余资源，若还有空余资源，可以利用控制信息调度区进行数据传输，若没有，则在该TTI内的调度可以结束，例如，网络设 备确定有待调度的用户设备需要传输上行数据，而此时该TTI正好是下行子帧，即数据调度区为下行数据调度区PDSCH，网络设备在确定上行控制信息调度区还有空余资源，即可利用上行控制信息调度区的空余资源传输该上行数据，而不必等到下一TTI再进行传输。又例如，网络设备确定有待调度的用户设备需要传输下行数据，而此时该TTI正好是上行子帧，即数据调度区为上行数据调度区PUSCH，网络设备在确定下行控制信息调度区还有空余资源，即可利用下行控制信息调度区的空余资源传输该下行数据，而不必等到下一TTI再进行传输。
本发明实施例提供的传输数据的方法，能够有效利用控制信道资源，并且提高了数据传输的效率。
应理解，在本发明实施例中，指示信息可以是下行控制信息DCI，也可以是下行数据，该下行数据具有指示作用，该下行数据可以用于指示用户设备在上行控制信息调度区的哪一位置传输上行数据和/或在下行控制信息调度区的哪一位置获取下行数据。优选地，该指示信息是下行控制信息。
还应理解，在本申请中，数据调度区是指承载数据传输的信道，控制信息调度区是指承载控制信息的信道。例如，如图3所示，下行数据调度区可以为PDSCH，下行控制信息调度区可以为物理下行控制信道PDCCH(Physical Downlink Control Channel，PDCCH)，上行数据调度区可以为PUSCH，上行控制信息调度区可以为物理上行控制信道PUCCH(Physical Uplink Control Channel，PUCCH)。
LTE系统中下行/上行业务的传输是基于网络设备调度的，调度的基本时间单位是一个子帧，一个子帧包括多个时域符号。具体的调度流程是网络设备发送控制信道，比如PDCCH，该控制信道可以承载PUSCH或PDSCH的调度信息，该调度信息包括比如资源分配信息，调制编码方式等控制信息。用户设备通过盲检获得的调度信息来进行下行数据信道的接收或上行数据信道的发送。举例来说，UE一般不知道当前PDCCH占用的控制信道单元(Control Channel Element，CCE)的数目大小，传送的是什么下行控制信息(Downlink Control Information，DCI)格式的信息，也不知道自己需要的信息在哪个位置。但是UE知道自己当前在期待什么信息，例如在Idle态UE期待的信息是寻呼消息；在有上行数据等待发送的时候期待上行链路授权等。对于不同的期望信息UE用相应的无线网络临时鉴定(Radio Network  Temporary Identifier，RNTI)去和CCE信息做循环冗余校验，如果循环冗余校验成功，那么UE就知道这个信息是自己需要的，也可以进一步知道相应的DCI格式以及调制方式，从而解出DCI内容。
当网络设备对一个用户设备分配完调度资源后，可以计算出该用户设备占用的数据信道资源，从而可以计算出用于承载数据的资源。类似地，网络设备也可以计算出调度该用户设备所占用的控制信道资源，从而可以计算出控制信道的剩余资源。若网络设备计算出可用于承载数据的资源为0，并且控制信道还有剩余资源，则可以利用控制信道的剩余资源进行数据的传输。
举例来说，若网络设备调度的传输时间间隔TTI采用的帧结构是如图3所示的下行子帧结构，即数据调度区为下行数据调度区PDSCH，网络设备在确定有待传输的下行数据时，可以先判断下行数据调度区PDSCH是否资源不足，在资源不足的情况下，可以进一步判断下行控制信息调度区是否有空余资源，若有，则利用下行控制信息调度区的空余资源传输该下行数据。类似地，若网络设备调度的传输时间间隔TTI采用的帧结构是如图3所示的上行子帧结构，即数据调度区为上行数据调度区PUSCH，网络设备在确定有待传输的上行数据时，可以先判断上行数据调度区PUSCH是否资源不足，在资源不足的情况下，可以进一步判断上行控制信息调度区是否有空余资源，若有，则利用上行控制信息调度区的空余资源传输该上行数据。
在数据调度区资源不足的情况下，利用控制信息调度区的剩余资源进行数据传输，不会造成控制信道资源的浪费，并且提高了数据传输的效率。
下面以在下行子帧内传输下行数据为例进行说明。图5示出了本发明实施例的传输数据的方法300，如图5所示，该方法300包括:
S310，在下行数据调度区调度下行数据，并确定所需的控制信道资源。本领域技术人员理解，下行数据调度区是指承载下行数据的信道资源，例如，下行数据调度区可以如图3所示的PDSCH，控制信道资源可以是PDCCH。具体地，基站确定所需的PDCCH资源和(Acknowledge，ACK)反馈所需的物理混合自动重传请求指示信道(Physical Hybrid Automatic Repeat reQuest Indicator Channel，PHICH)资源。
S320，确定下行数据调度区是否占满。若否，则继续执行S310，若是，则跳转到S330。具体地，网络设备决定着系统资源分配过程，即网络设备可以知道下行数据调度区的资源还有多少可以用来承载下行数据，若网络设 备判断出下行数据调度区还有空余资源，当还有下行数据需要传输时，则继续利用下行数据调度区的空余资源进行下行数据的传输，若没有空余资源，即已被占满，则跳转到S330。
S330，判断下行控制信息调度区是否还有空余资源。若判断出下行数据调度区已被占满，下行控制信息调度区还有空余资源时，则可以在下行控制信息调度区的空余资源继续向待调度的用户设备发送下行数据；若判断下行数据调度区已被占满，下行控制信息调度区没有空余资源时，则调度结束，等待下一个TTI再进行调度。应理解，该待调度的用户设备可以是已经被调度过下行数据的用户设备、也可以是小区内未调度下行数据的新用户设备。
S340，在下行控制信息调度区的空余资源调度下行数据。具体地，下行控制信息调度区的传输是以CCE的形式组织，1个CCE包括9个资源块组(Resource Element Group，REG)，每个REG由4个资源元素(Resource Element，RE)组成。每个用户设备可占用1个或多个CCE资源。
可选地，基站在下行控制信息调度区的空余资源调度下行数据可以包括两种方式。S341，基站可以为待调度的用户设备分配两套资源，即可以将控制信息调度区的剩余资源分为两部分，一部分用于为待调度的用户设备传输下行数据，一部分用于传输与该下行数据对应的下行控制信息，该下行控制信息包括位置指示信息，只有两者同时分配成功，才算是调度成功，用户设备通过盲检获取与其对应的下行控制信息，解析之后可以获得该下行数据所在的位置，故用户设备可以在确定的位置接收下行数据；S342，基站可以为待调度的用户设备分配一套资源，可以在基站发送的下行控制信息中增加标识信息，该标识信息用于标识该下行数据在该下行控制信息之后发送，例如，可以在下行控制信息中增加一个字段，该新增的字段为：content Flag：1bit，其中，0表示该下行控制信息仅仅为传统的控制信息，1表示在该下行控制信息之后是下行数据。应理解，本发明实施例仅以S341和S342提出的利用下行控制信息调度区的剩余资源调度下行数据为例进行说明，本发明对此不够成限定。
本领域技术人员理解，UE在接收下行数据时，需要通过盲检获得与其对应的DCI。UE在PDCCH搜索空间进行盲检时，只需对可能出现的DCI进行尝试解码，并不需要对所有的DCI格式进行匹配。UE进行PDCCH盲检的总次数不超过44次。当待传输的下行数据为小数据包时，优选采用上 述步骤S342的方式，可以将其伪装成下行控制信息，在该下行控制信息中添加标识信息，在UE接收到该下行控制信息之后，通过盲检直接可以获取该下行数据。而如果待传输的下行数据为大数据包时，UE进行盲检的可能性结果就比较多，因此，大数据包通常可以采用上述步骤S341的方式。
应理解，本申请中的下行数据调度区仅以PDSCH、下行控制信息调度区以PDCCH为例进行说明，本发明并不限于此。
下面详细说明本发明实施例的下行调度过程。假设小区内只有一个UE，且该UE需要的下行数据量比较大。首先，eNB进行下行信道质量测量。eNB发送小区特征参考信号给UE，UE估计信道质量指示(channel quality indication，CQI)并上报给eNB。UE上报CQI有两种方式：周期性和非周期性，可以同时存在，若同时上报的话，周期性的会被非周期性取代，仅发送非周期的CQI。至于小区特征参考信号是全频段的，针对整个小区的，在固定子帧位置上发送，每当UE需要上报CQI的时候就去参考这个RS信号，CQI不仅可以告诉eNB信道的质量，还可以包含推荐的编码调制方式。其二，eNB分配下行资源。ENB根据下行信道的质量好坏自适应地分配下行资源，通过PDCCH向UE下发DCI，该DCI的内容包括资源分配信息，调整编码方式等。其三，eNB判断PDSCH信道没有资源，但还有下行数据需要传输时，eNB进一步判断PDCCH信道是否有空余资源。其四，eNB在判断PDCCH信道还有空余资源时，将PDCCH划分为两部分，一部分用于传输剩余的下行数据，一部分用于传输与下行数据对应的下行控制信息。最后，UE通过盲检得到下行控制信息，根据该下行控制信息，在eNB分配的信道资源接收下行数据。
上述对在下行子帧内传输下行数据进行了详细描述，下面以在上行子帧内传输上行数据为例进行说明。图6示出了本发明实施例的传输数据的方法400，如图6所示，该方法400包括:
S410，调度用户设备在上行数据调度区调度上行数据，并确定所需的控制信道资源。本领域技术人员理解，上行数据调度区是指承载上行数据的信道资源。例如，上行数据调度区可以如图3所示的PUSCH，控制信道资源可以是PUCCH。具体地，基站调度小区内的用户设备执行周期和/或非周期SRS反馈、周期和/或周期CSI反馈、周期调度请求(Scheduling Request，SR)反馈，基站确定所需的控制信道资源，包括PUCCH资源和SRS资源。
S420，确定上行数据调度区是否占满。若否，则继续执行S410，若是，则跳转到S430。具体地，网络设备决定着系统资源分配过程，即网络设备可以知道上行数据调度区的资源还有多少可以用来承载上行数据，若网络设备判断出上行数据调度区还有空余资源，当还有上行数据需要传输时，则继续利用上行数据调度区的空余资源进行上行数据的传输，若没有空余资源，即已被占满，则跳转到S430。
S430，判断上行控制信息调度区是否还有空余资源。若在判断上行数据调度区已被占满，上行控制信息调度区还有空余资源时，则可以调度用户设备在上行控制信息调度区的空余资源继续发送上行数据；若在判断上行数据调度区已被占满，上行控制信息调度区没有空余资源时，则调度结束，等待下一个TTI再进行调度。应理解，该调度的用户设备可以是已经被调度过的用户设备、也可以是小区内未调度的新用户设备。
S440，向用户设备发送下行控制信息，调度用户设备在上行控制信息调度区的空余资源上传输上行数据。该下行控制信息用于指示用户设备使用哪些上行控制信道资源传输上行数据。具体地，可以按照PUCCH资源的粒度进行分配，从而能够最佳的利用上行控制信道调度区的空余资源。本领域技术人员理解，基站调度用户设备发送上行数据，即用户在发送上行数据之前，基站需要将自己的分配资源的结果告诉用户设备，即用户设备可以在哪个时间哪个载波上传输数据以及采用的调制编码方案。
应理解，本申请中的上行数据调度区仅以PUSCH、上行控制信息调度区以PUCCH为例进行说明，本发明并不限于此。
下面详细说明本发明实施例的上行调度过程。首先，UE向eNB请求上行资源。根据上层的配置UE按照一定的周期和子帧位置上通过PUCCH中的上行控制消息传输SR，即当UE有发送数据的需求时，就把相应得SR置1，没有资源请求时SR为空，并不是以报文的形式。SR只负责告诉eNB是否有资源需求，而具体需要多少资源则由之后的信令交互告诉eNB；其二，eNB进行上行信道质量测量。ENB给UE分配上行资源之前首先必须要知道上行信道的质量，如果UE的上行信道质量较好且有传输数据的需求，eNB才会给UE分配资源；其三，eNB分配资源并通过PDCCH将分配结果通知给UE。分配完资源后eNB还必须把分配的结果告诉UE，即UE可以在哪个时间哪个载波上传输数据，以及采用的调制编码方案；其四，UE接收资 源分配结果的通知。UE首先接收eNB下发的资源分配通知，监视PDCCH以查找可能的上行传输资源分配；其五，eNB判断PUSCH信道没有资源，但还有上行数据需要传输时，eNB进一步判断PUCCH信道是否有空余资源。其六，eNB在判断PUCCH信道还有空余资源时，向UE发送下行控制信息，调度用户设备利用PUCCH信道的空余资源传输上行数据。最后，UE根据接收到的下行控制信息，根据eNB分配的资源进行上行数据的传输。
本发明实施例提供的传输数据的方法，能够解决在数据调度区被占满，但还有数据需要传输或还有用户设备需要调度的情况下，利用控制信息调度区的剩余资源进行数据传输，从而可以不造成控制信道资源的浪费，提高了数据传输的效率。
可选地，下行控制信道资源占用该帧结构的3个正交频分复用OFDM符号，和/或上行控制信道资源占用该帧结构的3个正交频分复用OFDM符号。可以进一步保证控制信道资源足够多，不会成为控制信息传输的瓶颈。
可选地，该下行控制信息调度区承载以下至少一种信令：系统消息广播、随机接入响应(Random Access Response,RAR)、寻呼消息paging和信道状态指示参考信息(Channel State Information-Reference Signal，CSI-RS)。
具体地，在现有技术中，系统消息广播、随机接入响应、寻呼消息等高层信令是承载在PDSCH信道中，可以将这些信令中的至少一种在下行控制信息调度区发送，也可以将波束跟踪和无线资源管理(Radio Resource Management，RRM)测量用的CSI-RS，在下行控制信息调度区发送，使得上述这些高层信令和CSI-RS的调度不再受到原LTE TDD制式中的上行子帧/下行子帧配比的限制，能得到及时的调度和发送，减少了用户设备的接入时延。上述信令仅仅只是举例，还可以是超低型、超高可靠性机器类型通信(Ultra low delay and ultra reliable Machine Type Communication，UMTC)数据包等。本发明对此并不构成限定。
应理解，将重要的信令承载于下行控制信息调度区可以是在基站发送下行数据之前利用下行控制信息调度区预留的资源发送，也可以是在发送完下行数据之后，利用下行控制信息调度区的空余资源发送。

可选地，该指示信息包括位置指示信息，该位置指示信息用于指示用户设备在该上行控制信息调度区的空余资源的第一位置发送该上行数据，和/或在该下行控制信息调度区的空余资源的第二位置接收该下行数据，该在该上行控制信息调度区的空余资源发送该上行数据和/或在该下行控制信息调度区的空余资源获取该下行数据，包括：根据该指示信息，在该第一位置发送该上行数据和/或在该第二位置接收该下行数据。
可选地，该指示信息包括标识信息，该标识信息用于标识该下行数据在该指示信息之后传输，在该上行控制信息调度区的空余资源发送该上行数据和/或在该下行控制信息调度区的空余资源获取该下行数据，包括：根据该标识信息，在该指示信息之后获取该下行数据。
在指示信息中增加标识信息，使得用户设备可以通过一次盲检即可获得该下行数据。
应理解，网络设备侧描述的网络设备与终端设备的交互及相关特性、功能等与终端设备侧的相关特性、功能相应，为了简洁，在此不再赘述。
还应理解，在本发明的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
