Description

一种载波聚合方法、能力信息上报方法及装置
相关申请的交叉引用
本申请主张在2013年12月2日在中国提交的中国专利申请号No.201310637136.9的优先权，其全部内容通过引用包含于此。
技术领域
本发明涉及通信技术领域，尤其涉及一种载波聚合方法、能力信息上报方法及装置。
背景技术
现有长期演进(LTE，Long Term Evolution)系统只能工作在第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)标准化组织定义的分配给蜂窝移动通信系统的授权频段上工作，但随着移动互联网业务的飞速发展，业务量越来越大，现有授权频段逐渐无法满足LTE系统的频率需求。
现有LTE系统只能在给蜂窝移动通信系统分配的授权频段(licensed，频率分配给固定的使用者，排他性质的)工作，随着频率资源的紧缺，授权频段将无法满足未来的业务频率需求。我国已经为无线局域网络(WLAN，Wireless Local Area Networks)分配了2400-2483.5MHz、5150-5250MHz、5250-5350MHz和5725-5850MHz共计408.5MHz的免授权频段(Unlicensed，没有固定的频率使用者，只要满足频段的技术要求即可使用，无需向管理机构报备)，未来还可能开放5475-5725MHz的新的免授权频段。免授权频段有望成为授权频段的重要补充，但现有LTE系统还无法在免授权频段使用。
目前，一种实现在LTE系统中使用免授权频段的假想方案是，使用授权频段的载波和免授权频段的载波进行载波聚合的方案。
由于终端受到体积和成本的限制，终端的射频滤波器的能力有限，无法做到有效的射频隔离，若采用高性能滤波器，则在增加终端成本的同时，也带来更高的插损，造成网络覆盖性能的下降，覆盖成本的增加。
所以，终端在使用载波聚合进行通信时，在载波聚合的两个频段上很可能无法实现有效的射频隔离，原因包括：由于频段间隔较近导致射频难以实现，或者，免授权频段位置为授权频段的二次、三次、五次谐波，互调产物位置难以有效消除(如国际LTE FDD使用最广泛的band3的上行1710-1785MHz的三次谐波位于5130-5355MHz，其三次谐波产物正好落在免授权频段5150-5250MHz及5250-5350MHz内；Band41的上行2500-2690MHz的二次谐波位于5000-5380MHz，其二次谐波产物正好落在免授权频段5150-5250MHz及5250-5350MHz内；此外，两个授权频段双上行聚合加免授权频段聚合时，谐波和互调干扰产物更加复杂)，上述原因都可能导致终端在授权频段和免授权频段上无法同时进行收发，从而导致即便通过载波聚合方式使用免授权频段，也无法获得较好的通信性能。

具体实施方式
为了给出提高通过载波聚合方式使用免授权频段进行通信的性能的实现方案，本发明实施例提供了一种载波聚合方法、能力信息上报方法及装置，以下结合说明书附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。并且在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
本发明实施例提供一种使用免授权频段的载波聚合方法，应用于网络侧，如图1所示，包括：
步骤101、网络侧接收终端上报的表示终端是否支持在主载波上的上行发射和在辅载波上的下行接收同时进行的第一能力信息，其中，主载波为授权频段的载波，辅载波为免授权频段的载波。
步骤102、当该第一能力信息表示终端不支持在主载波上的上行发射和在辅载波上的下行接收同时进行时，禁止使用与主载波的上行发射位置对应的辅载波的下行子帧与终端通信。
相应的，本发明实施例提供一种能力信息上报方法，应用于终端侧，如图2所示，包括：
步骤201、终端向网络侧上报自身是否支持在主载波上的上行发射和在辅载波上的下行接收同时进行的第一能力信息，其中，主载波为授权频段的载波，辅载波为免授权频段的载波。
其中，该第一能力信息，可以用于网络侧当该第一能力信息表示所述终端不支持在主载波上的上行发射和在辅载波上的下行接收同时进行时，禁止使用与主载波的上行发射位置对应的辅载波的下行子帧与终端通信。
进一步的，在上述图1-图2所示方法中，当辅载波采用时分双工TDD方式时，网络侧还可以禁止使用与主载波的上行发射位置对应的辅载波的特殊子帧的下行正交频分复用OFDM符号与终端通信，其中，特殊子帧的下行OFDM符号，可以为下行导频时隙DwPTS的全部或部分OFDM符号。
在上述图1-图2所示方法中，当第一能力信息表示终端支持在主载波上的上行发射和在辅载波上的下行接收同时进行时，可以不进行相应的控制处理，即可以不限制与主载波的上行发射位置对应的辅载波的下行子帧和/或特殊子帧的下行OFDM符号的调度。
采用上述图1-图2所示方法，避免了当终端不支持在主载波上的上行发射和在辅载波上的下行接收同时进行时，如果使用与主载波的上行发射位置对应的辅载波的下行子帧与终端通信将无法得到较好通信性能的情况，即提高了通过载波聚合方式使用免授权频段进行通信的性能。
本发明实施例还提供一种使用免授权频段的载波聚合方法，应用于网络侧，如图3所示，包括：
步骤301、网络侧接收终端上报的表示终端是否支持在主载波上的下行接收和在辅载波上的上行发射同时进行的第二能力信息，其中，主载波为授权频段的载波，辅载波为免授权频段的载波。
步骤302、当该第二能力信息表示终端不支持在主载波上的下行接收和在辅载波上的上行发射同时进行时，禁止使用与主载波的下行接收位置对应的辅载波的上行子帧与终端通信。
相应的，本发明实施例还提供一种能力信息上报方法，应用于终端侧，如图4所示，包括：
步骤401、终端向网络侧上报自身是否支持在主载波上的下行接收和在辅载波上的上行发射同时进行的第二能力信息，其中，主载波为授权频段的载波，辅载波为免授权频段的载波。
其中，该第二能力信息，可以用于网络侧当该第二能力信息表示所述终端不支持在主载波上的下行接收和在辅载波上的上行发射同时进行时，禁止使用与主载波的下行接收位置对应的辅载波的上行子帧与终端通信。
进一步的，在上述图3-图4所示方法中，当辅载波采用TDD方式时，网络侧还可以禁止使用与主载波的下行接收位置对应的辅载波的特殊子帧的上行OFDM符号与终端通信，其中，特殊子帧的上行OFDM符号，可以为上行导频时隙UpPTS的全部或部分OFDM符号。
在上述图3-图4所示方法中，当第二能力信息表示终端支持在主载波上 的下行接收和在辅载波上的上行发射同时进行时，可以不进行相应的控制处理，即可以不限制与主载波的下行接收位置对应的辅载波的上行子帧和/或特殊子帧的上行OFDM的调度。
采用上述图3-图4所示方法，避免了当终端不支持在主载波上的下行接收和在辅载波上的上行发射同时进行时，如果使用与主载波的下行接收位置对应的辅载波的上行子帧与终端通信将无法得到较好通信性能的情况，即提高了通过载波聚合方式使用免授权频段进行通信的性能。
进一步的，上述图1-图2所示方法和图3-图4所示方法还可以相结合使用，即终端向网络上报上述第一能力信息和第二能力信息，可通过不同的消息携带上报，也可以在同一个消息中携带上报，网络侧在接收到第一能力信息和第二能力信息后，分别通过上述图1和图3所示流程进行对应的控制处理。
进一步的，在上述图1-图2所示方法中，在上述图3-图4所示方法中，以及在两者相结合的方法中，终端还可以使用主载波向网络侧上报辅载波下行子帧的确认字符/否定确认字符(ACK/NACK，Acknowledgement/Negative Acknowledgement)信息。
除采用上述方式向网络侧上报辅载波下行子帧的ACK/NACK信息之外，在上述图3-图4所示方法中，以及在两者相结合的方法中，终端还可以采用如下两种方式向网络侧上报辅载波下行子帧的ACK/NACK信息：
第一种方式：当与主载波的下行接收位置对应的辅载波的上行子帧，为用于上报辅载波下行子帧的ACK/NACK信息的子帧时，使用主载波向网络侧上报辅载波下行子帧的ACK/NACK信息；
否则，可以使用辅载波向网络侧上报辅载波下行子帧的ACK/NACK信息。
第二种方式：当与主载波的下行接收位置对应的辅载波的上行子帧，为用于上报辅载波下行子帧的ACK/NACK信息的子帧时，使用辅载波的下一个可用的且用于重传反馈的上行子帧向网络侧上报辅载波下行子帧的ACK/NACK信息；
否则，可以使用辅载波向网络侧上报辅载波下行子帧的ACK/NACK信 息。
并且，在上述第二种方式中，具体可以使用辅载波的下一个可用的且用于重传反馈的上行子帧，采用bundling方式向网络侧上报辅载波下行子帧的ACK/NACK信息和该下一个可用的且用于重传反馈的上行子帧原本需要反馈的ACK/NACK信息。
进一步的，在上述图3-图4所示方法中，以及在两者相结合的方法中，终端在向网络侧上报第一能力信息和第二能力信息，还可以优先使用主载波上报。
下面结合附图，以四种使用免授权频段的载波聚合方式为例，分别对本发明提供的方法进行详细描述。
实施例1：
在实施例1中，如图5A所示，在载波聚合中，主载波为授权频段的载波，辅载波为免授权频段的载波，并且，主载波采用频分双工(FDD，Frequency Division Duplexing)，其中，U表示上行子帧，D表示下行子帧，辅载波采用纯下行方式，即仅进行下行传输，D表示下行子帧。
图6为本发明实施例1中使用免授权频段的载波聚合方法的流程图，具体包括如下步骤：
步骤601、终端获取自身是否支持在主载波上的上行发射和在辅载波上的下行接收同时进行的第一能力信息。
该第一能力信息可以是在终端出厂时预先在终端上进行配置的，终端可以直接获取。
步骤602、终端向网络侧上报第一能力信息。
由于辅载波采用纯下行方式，所以本步骤中，终端使用主载波向网络侧上报第一能力信息。
该第一能力信息可以使用1bit的指示信息，例如，当该1bit的指示信息的值为1时表示支持，为0时表示不支持。
步骤603、网络侧在接收到第一能力信息后，当第一能力信息表示终端不支持在主载波上的上行发射和在辅载波上的下行接收同时进行时，禁止使用与主载波的上行发射位置对应的辅载波的下行子帧与终端通信，即相当于 对与主载波的上行发射位置对应的辅载波的下行子帧不进行调度。
例如，如图5B所示，主载波的上行发射位置包括上行子帧U1和U2(以灰色区域形式表示的上行子帧为上行发射位置)，则不允许使用对应的辅载波的下行子帧D1和D2进行通信(以阴影区域形式表示的下行子帧为不允许使用的下行子帧)。
本步骤具体可以由网络侧与终端之间的信息交互完成控制，具体的控制机制可以根据实际需要灵活的采用各种机制，在此不再进行详细描述。

该第一能力信息和第二能力信息可以是在终端出厂时预先在终端上进行配置的，终端可以直接获取。
步骤802、终端向网络侧上报第一能力信息和第二能力信息。

步骤803、网络侧在接收到第一能力信息后，当第一能力信息表示终端不支持在主载波上的上行发射和在辅载波上的下行接收同时进行时，禁止使用与主载波的上行发射位置对应的辅载波的下行子帧和/或特殊子帧的下行OFDM符号与终端通信，即相当于对与主载波的上行发射位置对应的辅载波的下行子帧和/或特殊子帧的下行OFDM符号不进行调度。
例如，如图7B所示，主载波的上行发射位置包括上行子帧U1(以灰色区域形式表示的上行子帧为上行发射位置)，则不允许使用对应的辅载波的下行子帧D1进行通信(以阴影区域形式表示的下行子帧为不允许使用的下行子帧)。
本步骤具体可以由网络侧与终端之间的信息交互完成控制，具体的控制机制可以根据实际需要灵活的采用各种机制，在此不再进行详细描述。
