Description

一种在非授权频段上的数据传输方法及装置
本申请要求在2014年11月5日提交中国专利局、申请号为201410638168.5、发明名称为“一种在非授权频段上的数据传输方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及移动通信技术领域，尤其涉及一种在非授权频段上的数据传输方法及装置。
背景技术
随着移动数据业务量的不断增长，频段资源越来越紧张，仅使用授权频段资源进行网络部署和业务传输可能已经不能满足移动数据业务量需求，可以考虑在非授权频段资源上部署传输移动数据业务，以提高频段资源利用率和改善用户体验。非授权频段作为辅载波由授权频段的主载波辅助实现移动数据业务的传输。
非授权频段可以为多种无线通信系统如蓝牙、Wi-Fi等共享，多种无线通信系统间通过竞争资源的方式使用共享的非授权频段资源。故不同运行商部署的LTE-U(Unlicensed Long Term Evolution，简称为U-LTE或者LTE-U)间及LTE-U与Wi-Fi等无线通信系统的共存性是研究的一个重点与难点。
LTE系统支持FDD(Frequency Division Duplexing，频分双工)和TDD(Time Division Duplexing，时分双工)两种双工方式，两种双工方式使用不同的帧结构。两种帧结构的共同点是每个无线帧由10个1ms子帧组成。FDD系统使用第一类帧结构如图1所示，TDD系统使用第二类帧结构，如图2所示。
从LTE帧结构可看出，其传输的数据都是以时间长度为1ms的子帧为单位的，但对LTE-U来说，受LBT(Listen Before Talk，先监听后通讯)竞争接入、基站数据准备时间及基站射频准备时间等因素影响，LTE-U信号传输的时间起点可能是某个子帧的任何位置，导致发送的是一个不完整子帧，即时间上少于一个正常子帧长度的物理资源。不完整子帧如果不发信号，在资源竞争激烈情况下该资源必然会被其它节点抢去。
由于LTE-U设计要求保证LTE-U与Wi-Fi公平竞争，因此LTE-U一次传输的时间为10ms是较合适的，一次传输最好不超过40ms。若LTE-U一次传输的最大时间为10ms，竞争接入所处子帧是不完整子帧必然导致最后可用的子帧也是不完整子帧，若两个不完整子帧都不传输数据，会导致LTE-U传输效率损失至少10％，若LTE-U一次传输的时间最大为4ms，两个不完整子帧都不传输数据，会导致LTE-U传输效率损失至少25％，因此无论从资源利用还是从技术角度去分析，不完整子帧中不传输数据都是不可接受的。因此在 不能够发送完整子帧的资源上发送不完整子帧，并通过不完整子帧发送数据，能够提高数据传输效率，避免资源的浪费。如何在LTE非授权频段上通过不完整子帧进行数据传输还没有完整的解决方案。
综上所述，现有技术中如何在非授权频段上通过不完整子帧传输数据还没有解决方案。

具体实施方式
在通信系统中，在非授权频段上通过不完整子帧传输待传输数据时，用户设备(User Equipment，UE)无法确定接收到的不完整子帧内待传输数据的结束位置。网络设备在竞争资源时，受LBT竞争接入、网络设备数据准备时间及网络设备射频准备时间等因素影响， 经常会出现不能传输一个完整子帧的情况，为了提高资源利用率，只能通过不完整子帧进行数据传输。不完整子帧的长度小于一个完整子帧的长度，例如在LTE系统中，常规CP时一个完整子帧只有14个OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)符号可用，而少于14个OFDM符号的子帧就是不完整子帧。
在无线帧中包括不完整子帧时，对用户设备来说，待传输信息块的起始位置是已知的或者固定的，其结束位置是不确定或可变的，待传输信息块的长度小于一个子帧的长度；对网络设备来说待传输信息块的起始位置与结束位置虽然都是已知的，但起始位置相对固定，结束位置是变化的。由于传输数据的结束位置是不确定或可变的，其起始位置是已知的或者固定的，用户设备在无法确定不完整子帧内数据传输的结束位置的情况下是无法获得传输的数据的。
为了解决用户设备无法确定接收到的无线帧内待传输数据的结束位置的问题，本发明实施例中，网络设备在发送无线帧时，通过发送位置指示信息以向用户设备指示无线帧内待传输数据的结束位置，从而使用户设备能够确定无线帧内数据传输的结束位置，进而正确获取不完整子帧中的数据。
本发明实施例分别基于网络侧和用户设备侧提供了一种在非授权频段上的数据传输方法。其中，网络侧的传输方法和用户设备侧的传输方法可分别独立使用，也可结合使用。下面分别对网络侧和用户设备侧的传输方法进行描述。
本发明实施例中描述的方法适用于多种移动通信系统中，本发明实施例现仅以LTE系统为例进行描述，其他移动通信系统不在赘述。本发明实施例中术语“符号”在以LTE系统为例进行描述时是指OFDM符号。
下面结合说明书附图对本发明实施例做详细描述。
如图3所示，本发明实施例提供的一种在非授权频段上的数据传输方法流程图，该流程由网络设备执行，所述网络设备可以是具有网络接入功能的设备，比如可以是基站。如图所示，该流程可包括：
步骤301：确定在非授权频段上的无线帧中待传输数据的结束位置；
步骤302：根据所述结束位置确定位置指示信息，其中，所述位置指示信息用于指示用户设备根据所述位置指示信息确定所述非授权频段上的无线帧中待传输数据的结束位置；
步骤303：发送所述位置指示信息给用户设备。
在LTE系统中，无线帧中待传输数据映射到PDSCH(Physical Downlink Shared Channel，物理下行共享信道)中传输。由于PDSCH与ePDCCH(Enhanced Physical Downlink Control Channel，增强物理下行控制信道)可以频分复用，这种情况下，PDSCH与ePDCCH的时域起点相同，因此上述待传输数据的结束位置是指无线帧中不完整子帧的 PDSCH或ePDCCH的结束OFDM符号。
通过所述位置指示信息所指示出的待传输数据的结束位置是指待传输数据在无线帧中结束符号的序号，或者结束符号在所述无线帧内的相对位置。其中，相对位置是指待传输数据的结束符号距离该待传输数据所在的无线帧或子帧起点算起的符号数目，或者距离该无线帧或子帧起点算起的符号数目，或其他实质等同的信息。
上述流程的步骤302中，确定出的所述位置指示信息可以是网络设备与用户设备约定的序列；或者，该位置指示信息通过信令发送。
如果位置指示信息为序列，则该序列需要网络设备与用户设备预先约定，即，所述序列是一个网络传设备与用户设备都已知的序列。所述序列可以在用户设备的本地存储，或者在用户设备生成。所述序列的一种可实现的生成方法是利用PN(Pseudo-Noise,伪噪声)序列或者CAZAC(Constant Amplitude Zero Auto Correlation，恒包络零自相关)序列为基序列构造而成。所述序列也可以有其他的生成方法，在此不再赘述。
在步骤303中，网络设备发送所述序列时，该序列一般位于不完整子帧的最后一个完整可用OFDM符号上，也可以位于最后一个完整可用的OFDM符号之前的某个OFDM符号上。所述序列在频域上占据全部带宽或指定的部分带宽。
当序列在频域上占据全部带宽或指定的部分带宽时，所述序列所在的符号在时域上位于传输所述待传输数据的起始符号与结束符号之间的任一约定的符号上或者传输所述待传输数据的起始符号上，比如，网络设备在传输PDSCH的结束OFDM符号的前一个OFDM符号上发送所述序列。
当序列占指定的部分带宽时，所述序列所在的符号为传输所述待传输数据的所述结束符号。比如，网络设备在传输PDSCH的结束OFDM符号上发送所述序列，且PDSCH与该序列通过频分复用的方式占用不同的带宽。优选的，当位置指示信息为一个序列时，可以通过子帧所在的非授权频段载波承载序列。
如果位置指示信息通过信令发送，则信令位于网络设备与用户设备预先约定的符号上。此时位置指示信息发送位置是固定的，不需要用户设备盲检。
网络设备可以将信令配置在竞争接入时所处子帧至传输所述待传输数据的最后一个完整可用的符号所处子帧之间的任一子帧中预先约定的符号上。优选的，可以利用竞争接入时所处子帧的某个OFDM符号中承载的信令指示传输时间与最后一个子帧的结束OFDM符号。具体的，LTE在非授权频段竞争接入后，一次占用信道传输的最大时间对用户设备来说已知的，且该时间较合理的为子帧所占时间长度的整数倍，故网络设备在竞争接入时刻所处的子帧上，便可以确定最后不完整子帧的OFDM符号终点的位置。较佳的，信令配置在所述竞争接入时所处子帧的最后一个完整可用的符号上。用户设备都去解码该信令，从而不管用户设备是否有数据传输都能够获得网络设备一次占用信道的终点。网络 设备获得信道后对信道的占用时间是可以配置的，也可以将网络设备将占据的信道传输时间，通过指示最后子帧的结束OFDM符号的位置的方式加以指示，如将最后子帧结束OFDM符号指示为接入子帧后的第M个子帧第L个OFDM符号，其中M与L为非负整数，实现整个传输时间与最后子帧结束OFDM符号的指示。
信令还可以位于最后子帧的某个约定的OFDM符号上，较佳的，该信令位于最后子帧的最前面第N个OFDM符号上(N为正整数)，此时该信息发送位置是固定的，不需要用户设备检测其位置。优选的，所述指定的符号位于最后子帧内最后一个完整可用的符号上。此时信令可以在不完整子帧所在的载波上承载，也可以由其他载波承载，跨载波指示不完整子帧的终止符号，即信令由非授权频段上的载波承载，或由授权频段上的主载波或辅载波承载。优选的，在授权频段承载信令。
用户设备解码最后一个子帧时，用户设备已经借助发现信号等手段实现时间与频率同步，确定了最后子帧的头部边界，若待传输信息块的位置指示信息配置在最后子帧的第一个OFDM符号的K个RB(Resource Block，资源块)上传输，K为非负整数，用户设备在该子帧的第一个OFDM符号的K个RB中获得了位置指示信息后即可对该子帧解码。
所述信令在频域上占据约定的符号的全部带宽或部分带宽。优选的，位置指示信息一般用若干个比特指示PDSCH或ePDCCH的结束OFDM符号的序号，或指示者PDSCH或ePDCCH的结束OFDM符号的序号在最后子帧中的相对位置，具体使用几个比特根据实际情况确定。当所述信令占指定的部分带宽时，所述信令可以与其他信息(比如控制信道或者待传输数据)以频分复用方式占用同一个符号。例如，信令可以在PDSCH的结束OFDM符号上发送，且与PDSCH通过频分复用的方式传输。
信令还可以由非授权频段辅载波的PDSCH的DL grant或者ePDCCH的DL grant指示；也可以由授权频段上的主载波的PDSCH的DL grant或者ePDCCH的DL grant指示。例如可以用公共搜索空间承载指示信令的DL grant。
LTE系统在子帧上传输数据时，由于L1/L2控制信道位于一个完整子帧的前P个OFDM符号上，其中，P小于等于4，在非授权频段上的不完整子帧中，L1/L2控制信道占据的OFDM符号一般是存在的，故可采用LTE协议中PDCCH与PDSCH时分复用方案，最大化的利用原LTE协议。
但是如果不完整子帧中OFDM符号数量较少时，例如只有3个完整可用的OFDM符号，此时根据LTE协议，控制信道频域占用全带宽，时域至少占用的1个OFDM符号，即控制开销最少占用可用资源的1/3，甚至更大，显然会降低资料的利用率。此时，可以放弃R8/R9的传统L1/L2控制区域，而是采用ePDCCH与PDSCH频分复用方案。待传输数据的结束位置所在的子帧一般为不完整子帧，因此在所述待传输数据的结束位置所在的子帧中，PDSCH和ePDCCH采用频分复用的方式传输，所述PDSCH和所述ePDCCH的 时域起点相同，所述PDSCH和所述ePDCCH的时域终点相同；所述PDSCH和所述ePDCCH的时域起点位于所述待传输数据的结束位置所在的子帧的起点。
根据本发明实施例提供的方法，通过位置指示信息向用户设备指示非授权频段上的无线帧内传输数据的结束位置，使得用户设备能够根据该位置指示信息确定无线帧内传输数据的结束位置，从而正确接收数据。
如图4所示，本发明实施例提供的另一种在非授权频段上的数据传输方法流程图，该流程由用户设备执行，所述用户设备可以是具有无线通信功能的用户设备，比如可以是手机。
该流程可包括：
步骤401：接收非授权频段上的无线帧的位置指示信息；
步骤402：根据所述位置指示信息确定所述非授权频段上的无线帧内传输数据的结束位置。
其中，所述位置指示信息的含义以及发送方式，与图3中的相应内容相同，在此不再赘述。
在所述位置指示信息是网络设备与用户设备约定的序列的情况下，步骤401中，当用户设备在无线帧上检测到所述序列时，步骤402中，用户设备能够根据预先约定的序列的值，以及所述序列所在的符号位置便能确定接收到的无线帧中的传输数据的结束位置，进而可解调出数据。
在所述位置指示信息是通过信令发送的情况下，步骤401中，用户设备通过非授权频段上的辅载波或者授权频段上的主载波获得所述信令以及所述信令对应的子帧，就可以获得该子帧内的传输数据的结束位置。
例如，LTE系统中，用于指示所述位置指示信息的信令预先约定位于无线帧的最后一个子帧的最后一个OFDM符号上的频段中间的第K个RB上传输。用户设备借助发现信号等手段实现时间与频率同步后，可以确定不完整子帧的尾部边界，并在该不完整子帧的最后一个OFDM符号上频段中间的第K个RB上检测到信令，从而可以根据该信令获得该子帧中传输数据的结束位置。
如前所述，网络设备可以采用ePDCCH与PDSCH频分复用方案，提高资源利用率。
根据本发明实施例提供的方法，用户设备在非授权频段上接收到无线帧后，通过网络设备发送的位置指示信息确定无线帧内传输数据的结束位置，使得用户设备能够根据该位置指示信息确定无线帧内传输数据的结束位置，从而正确接收数据。
根据上面的描述，位置指示信息可以有两种表示方式，下面以LTE系统为例，结合图5至图8描述各种组合方案下最后一个子帧为不完整子帧时的结构示意图。
如图5所示，待传输数据映射在PDSCH上发送，ePDCCH与PDSCH时分复用。PDSCH 与ePDDCH的时域起点相同，均位于该不完整子帧的起始点。位置指示信息为网络设备与用户设备约定的序列。
该序列位于该不完整子帧的最后一个完整可用的OFDM符号上，可以占全部带宽也可占部分带宽，当占部分带宽时PDSCH与ePDCCH也可以占据该序列所在的OFDM符号的频域资源。
用户设备首先将最后不完整子帧全部缓存下来，然后对该已知序列进行检测，一旦检测到尾部位置序列即可以确定不完整子帧的终止OFDM符号，从而实现对ePDCCH与PDSCH解调。
如图6所示，待传输数据映射在PDSCH上发送，ePDCCH与PDSCH频分复用。PDSCH与ePDDCH的时域起点相同，均位于该不完整子帧的起始点。位置指示信息为信令。该信令占据部分带宽，与PDSCH采用频分复用的方式共同占据一个OFDM符号，该序列所在的OFDM符号位于PDSCH的起始OFDM符号。
用户设备检测到该信令后确定出该子帧结束OFDM符号的位置，然后根据结束OFDM符号的位置，解码ePDCCH与PDSCH。
如图7所示，待传输数据映射在PDSCH上发送，ePDCCH与PDSCH频分复用。PDSCH与ePDDCH的时域起点相同，均位于该不完整子帧的起始点。位置指示信息为信令。该信令位于网络设备竞争接入时刻所处子帧的某个OFDM符号上。
用户设备在竞争接入时刻所处子帧的某个OFDM符号上检测到该信令后，确定出该不完整子帧的结束OFDM符号的位置，然后根据结束OFDM符号的位置，解码ePDCCH与PDSCH。
如图8所示，位置指示信息为信令，该信令配置在最后不完整子帧的第一个OFDM符号的K个RB上传输。当然也可以位于不完整子帧的某个特定OFDM符号上。此时该信令发送位置是由网络设备与用户设备约定的，不需要用户设备检测其位置。用户设备在解码最后一个不完整子帧时，已经借助发现信号等手段实现时间与频率同步，确定了该不完整子帧的起始符号，再根据不完整子帧的第一个OFDM符号的K个RB上的信令确定待传输数据的结束符号后，即可对最后不完整子帧解码。
针对上述方法流程，本发明实施例还提供一种网络设备和一种用户设备，该网络设备和用户设备的具体内容可以参照上述方法实施，在此不再赘述。
