应理解,本发明的技术方案可以应用于各种通信***,例如:全球移动通讯(Global System of Mobile communication,GSM)***、码分多址(Code Division Multiple Access,CDMA)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)***、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)***、先进的长期演进(Advanced long term evolution,LTE-A)***、通用移动通信***(Universal Mobile Telecommunication System,UMTS)等。
还应理解,在本发明实施例中,用户设备(UE,User Equipment)包括但不限于移动台(Mobile Station,MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等,该用户设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等,用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。

实施例一
针对现有技术中存在的问题,本发明实施例一提供一种基于TM9的载波聚合方法,如图2所示,该基于TM9的载波聚合方法具体包括以下步骤:
步骤201,网络侧设备确定载波聚合***中当前已经激活的成员载波。
本发明实施例中,在载波聚合***中,载波聚合过程具体包括但不限于:载波聚合小区的配置过程以及辅成员载波的激活/去激活过程。
在载波聚合小区的配置过程中,将一个成员载波配置为主成员载波,将其它一个或者多个成员载波配置为辅成员载波。进一步的,当载波聚合关系添加之后,还可以配置一组载波聚合参数,例如,上行载波聚合开关、下行载波聚合开关、载波聚合跨载波调度开关、载波聚合激活/去激活比例门限、载波聚合激活数据量门限、载波聚合去激活数据量门限等。进一步的,还可以设置一组默认的载波聚合参数到载波聚合关系中,此参数可具体调整。
在辅成员载波的激活/去激活过程中,可以按照表1所示的激活/去激活算法执行辅成员载波的激活/去激活处理。例如,当载波聚合关系配置好之后,如果UE1附着在主成员载波上,此时UE1上的数据流达到载波聚合激活数据量门限,并且各项参数达到了载波聚合的条件,则辅成员载波将被激活。
表1
基于上述处理,网络侧设备可以确定出载波聚合***中当前已经激活的成员载波,并确定当前已经激活的成员载波中是否有配置TM9的成员载波。
步骤202,如果当前已经激活的成员载波中有配置TM9的成员载波,则针对配置TM9的成员载波,网络侧设备确定该成员载波的传输模式。
本发明实施例中,当辅成员载波被激活之后,主成员载波和辅成员载波的调度是分别进行的,即按照一般的策略来说,主成员载波和辅成员载波是独立调度的,各自根据UE情况,确定自己的传输模式和下行控制信息(Downlink Control Information,DCI)格式。对于配置TM9的成员载波,按照本发明实施例提供的技术方案处理,对于未配置TM9的成员载波,按照现有技术处理。例如,TD-LTE小区A为主成员载波,TD-LTE小区A配置的传输模式为TM3,LTE-A小区B为辅成员载波,LTE-A小区B配置的传输模式为TM9,则:对于配置TM9的成员载波(LTE-A小区B),按照本发明实施例提供的技术方案处理,该处理在后续过程中详细说明;对于配置TM3的成员载波(TD-LTE小区A),按照现有技术处理,该处理本发明实施例中不再赘述。
本发明实施例中,当配置TM9的成员载波为辅成员载波时,网络侧设备确定成员载波的传输模式,具体包括但不限于:网络侧设备判断UE是否支持上行载波聚合功能;如果UE支持上行载波聚合功能,则在码本条件下,网络侧设备确定成员载波的传输模式为码本TM9;或者,在非码本条件下,网络侧设备确定成员载波的传输模式为非码本TM9;如果UE不支持上行载波聚合功能,则在码本条件下,网络侧设备确定成员载波的传输模式为码本TM9;或者,在非码本条件下,网络侧设备确定成员载波的传输模式为TM3。
进一步的,网络侧设备确定成员载波的传输模式为码本TM9的过程,具体包括但不限于:网络侧设备判断本网络侧设备配置的端口数是否大于等于4;如果本网络侧设备配置的端口数不大于等于4,则网络侧设备确定成员载波的传输模式为码本TM9单流或者码本TM9双流;如果本网络侧设备配置的端口数大于等于4,则网络侧设备判断UE最大支持的流数是否大于等于4;如果UE最大支持的流数不大于等于4,则网络侧设备确定成员载波的传输模式为码本TM9单流或者码本TM9双流;如果UE最大支持的流数大于等于4,则网络侧设备确定成员载波的传输模式为码本TM9四流或者码本TM9八流。
其中,由于上行载波聚合功能需要UE有两根发送天线,主成员载波和辅成员载波同时发送上行数据。因此,如果UE支持上行载波聚合功能,则可以在辅成员载波发送上行数据,在码本条件下,网络侧设备确定成员载波的传输模式为码本TM9;或者,在非码本条件下,网络侧设备确定成员载波的传输模式为非码本TM9。如果UE不支持上行载波聚合功能,则UE上行只支持一个成员载波,即主成员载波,对于辅成员载波来说,在码本条件下,网络侧设备确定成员载波的传输模式为码本TM9;或者,在非码本条件下,网络侧设备确定成员载波的传输模式为TM3,而不能是非码本TM9。
本发明实施例中,当配置TM9的成员载波为主成员载波时,网络侧设备确定成员载波的传输模式的过程,具体包括但不限于如下方式:在码本条件下,网络侧设备确定成员
载波的传输模式为码本TM9;或者,在非码本条件下,网络侧设备确定成员载波的传输模式为非码本TM9。
进一步的,网络侧设备确定成员载波的传输模式为码本TM9的过程,具体包括但不限于:网络侧设备判断本网络侧设备配置的端口数是否大于等于4;如果本网络侧设备配置的端口数不大于等于4,则网络侧设备确定成员载波的传输模式为码本TM9单流或者码本TM9双流;如果本网络侧设备配置的端口数大于等于4,则网络侧设备判断UE最大支持的流数是否大于等于4;如果UE最大支持的流数不大于等于4,则网络侧设备确定成员载波的传输模式为码本TM9单流或者码本TM9双流;如果UE最大支持的流数大于等于4,则网络侧设备确定成员载波的传输模式为码本TM9四流或者码本TM9八流。
其中,本发明实施例中,可以将配置TM9的成员载波作为辅成员载波,也可以将配置TM9的成员载波作为主成员载波。进一步的,无论UE是否支持上行载波聚合功能,主成员载波需要始终是激活的。
步骤203,网络侧设备按照传输模式(即步骤202中确定的配置TM9的成员载波的传输模式)向UE传输数据。其中,网络侧设备在确定成员载波(如主成员载波或者辅成员载波)的传输模式之后,还可以根据信道环境调整数据传输的格式,并利用该数据传输的格式向UE传输数据。
本发明实施例中,网络侧设备在确定成员载波的传输模式之后,在数据传输过程中,网络侧设备还可以将成员载波(如配置TM9的主成员载波或者辅成员载波)的传输模式发送给UE,由UE接收成员载波的传输模式。
进一步的,在成员载波的传输模式为码本TM9单流或者码本TM9双流,且辅成员载波开启模式间自适应功能时,如果UE的参考符号接收功率(Reference Signal Received Power,RSRP)大于预设第一阈值,且UE的信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)大于预设第二阈值,则UE将传输模式自适应到TM3;否则,UE将传输模式自适应到TM9单流或者TM9双流。进一步的,在成员载波的传输模式为码本TM9四流或者码本TM9八流,且辅成员载波开启模式间自适应功能时,如果UE的RSRP大于预设第三阈值,且UE的SINR大于预设第四阈值,则UE将传输模式自适应到TM9四流或者TM9八流;否则,UE将传输模式自适应到TM3。
其中,预设第一阈值、预设第二阈值、预设第三阈值和预设第四阈值均可以根据实际经验任意设置。当UE的RSRP大于预设第一阈值时,表示RSRP值较好,如预设第一阈值为-100dBm。当UE的SINR大于预设第二阈值,表示SINR值较好,如预设第二阈值为18dB。当UE的RSRP大于预设第三阈值时,表示RSRP值较好,如预设第三阈值为-100dBm。当UE的SINR大于预设第四阈值,表示SINR值较好,如预设第四阈值为18dB。
综上所述,本发明实施例至少具有以下优点,本发明实施例中,可以使载波聚合小区
支持对下行8端口的TM9的TD-LTE-A小区进行载波聚合,从而能够提高用户速率,并增强用户体验。进一步的,上述方式增加了最大支持数据流数、UE能力等检查点,用以提高用户吞吐量。进一步的,通过在现有TD-LTE小区载波聚合基础上,考虑将TM9小区作为辅成员载波激活的情况,将辅成员载波小区使用何种传输模式来传输数据,增加了最大支持数据流数、UE能力等检查点,用以提高用户吞吐量,提高载波聚合用户的速率。
