Description

在使用载波的移动通信系统禁用副载波的方法和装置
技术领域
本发明涉及移动通信系统。更具体地，本发明涉及一种用于在使用载波聚合（CA）的长期演进（LTE）系统中禁用副载波的方法。
背景技术
近年来，随着无线通信技术的快速进步，移动通信系统已经跨代发展。当前，长期演进（LTE）系统作为第四代移动通信系统受到注目。为了满足业务需求的爆炸式增长，包括载波聚合（CA）的各种技术已经被引入到LTE系统中。在大多数情况下，在用户设备（UE）和演进节点B（eNB）（例如，基站）之间的通信中使用单载波。当采用载波聚合时，主载波和一个或多个副载波可以被使用在用户设备和基站之间的通信中，从而显著地将数据传输速率增加与副载波的数量相对应的量。在LTE系统中，主载波被称为主小区（PCell），并且副载波被称为副小区（SCell）。
对于载波聚合，需要额外的努力来控制在主小区处的副小区。例如，可以进行在特定的主小区处是否使用副小区的判定，可以确定对于用于激活和禁用副小区的条件的判定，以及可以监视用于激活和禁用副小区的条件。更具体地，需要指定禁用副小区的具体方案。
因此，需要有一种执行设备的自诊断系统和方法，而没有当从计算机或者用户界面中手工地选择自诊断项目时所导致的不便。
以上信息作为背景资料而呈现，其仅仅用于协助对于本公开的理解。关于上述中的任何一项是否可以被应用作为有关本发明的现有技术，并没有进行判定，并且也没有进行断言。

因此，需要有一种执行设备的自诊断系统和方法，而没有当手工地从计算机或者用户界面中选择自诊断项目时所导致的不便。

本发明的示例性实施例涉及一种用于在利用载波聚合（CA）的用户设备（UE）中禁用副载波的方法和装置。
图1示出了根据本发明示例性实施例的长期演进（LTE）系统架构。
参照图1，LTE无线接入网络包括基站，诸如，例如，演进型节点B（eNB）105、110、115、和120，移动性管理实体（MME）125、以及服务网关（S-GW）130。用户设备（UE）135可以通过eNB105至120（例如，105、110、115、和120）和S-GW130而连接到外部网络。
基站105至120对应于通用移动电信系统（UMTS）的节点B。eNB通过无线信道而连接到用户设备135，并且与现有的节点B相比可以执行比较复杂的功能。在LTE系统中，因为包括诸如，例如，互联网语音协议（VoIP）服务的实时服务的所有用户业务通过共享信道来服务，所以需要基于收集的关于缓冲器的状态信息、可用传输功率、以及用户设备的信道来执行调度。每个eNB105至120执行此调度功能。在大多数情况下，单个的eNB控制多个小区。为了实现100Mbps的数据速率，LTE系统使用20MHz带宽的正交频分复用（OFDM）来作为无线接入技术。LTE系统采用自适应调制和编码（AMC）来确定根据用户设备的信道状态的调制方案和信道编码率。S-GW130提供数据承载，并且在MME125的控制下创建和删除数据承载。MME125执行包括用于用户设备的移动性管理的各种控制功能，并且连接到多个eNB。
图2示出根据本发明示例性实施例的长期演进（LTE）系统中的无线协议的分层结构。
参照图2，在LTE系统中，用户设备和eNB的每个包括由分组数据汇聚协议（PDCP）层205或240、无线电链路控制（RLC）层210或235、媒体接入控制（MAC）层215或230、以及物理层（PHY）220或225构成的无线协议栈。PDCP层205或240执行IP报头的压缩与解压缩。RLC层210或235将PDCP协议数据单元（PDU）重新配置为合适的尺寸，以进行自动重传请求（ARQ）操作。MAC层215或230被连接到在用户设备中的多个RLC层设备，并且将RLC PDU复用为MAC PDU，或者将MAC PDU解复用为RLC PDU。物理层220或225通过信道编码和调制将上级层的数据转换为OFDM符号并且通过无线信道传输OFDM符号；或者通过解调和信道解码，将通过无线通道接收的OFDM符号转换为上级层的数据，并且将数据转发到更高的层。
图3示出根据本发明示例性实施例的，在用户设备（UE）处的载波聚合（CA）。
参照图3，eNB305通过多个频段上的多个载波来传输和接收信号。例如，假设eNB305使用中心频率为f1的载波315和中心频率为f3的载波310。普通用户设备使用两个载波310和315中的一个来发送和接收数据。具有载波聚合的能力的用户设备330可以使用包括并行的载波310和315的多个载波，以发送和接收数据。因此，eNB305可以根据服务条件来分配两个或多个载波到具有载波聚合能力的用户设备330，从而提高了用户设备330的数据速率。
在传统的意义上，可以认为一个小区由同一基站提供的下行链路载波和上行链路载波形成。在载波聚合中，用户设备可以被认为是并行地通过多个小区来发送和接收数据。因此，用户设备的最大数据传输速率可以与聚合载波的数目成比例地增加。
在描述中，当用户设备通过下行链路载波接收到数据，并且通过上行链路载波发送数据时，其对应于在其中用户设备使用由与特征为载波的中心频率以及频带对应的小区提供的控制和数据信道来发送和接收数据的情况。为了便于描述，本发明的示例性实施例聚焦于LTE系统。然而，本发明的示例性实施例可以被应用于支持载波聚合的各种无线通信系统。
图4是根据本发明示例性实施例的，描述用于禁用副载波的方法的消息序列图。
参照图4，在步骤405中，eNB403向用户设备401发送指示所配置的SCell中的一个被激活/停用的激活/禁用MAC控制元素（CE）。例如，激活/禁用MAC CE是8位的MAC CE，并且包括七个C字段和一个R（即，保留）字段。七个C字段可以由C7、C6、C5、C4、C3、C2、和C1来表示。设置为“1”的Ci指示SCell i被激活，并且设置为“0”的Ci指示SCell i被禁用（即，其中，i对应于正整数）。也就是说，激活/禁用MAC CE指示被分配给用户设备的副载波的激活或禁用。
在接收激活/禁用MAC CE之后，用户设备401在步骤407中识别要被激活或禁用的SCell。当特定的SCell被激活时，在步骤409中，用户设备401激活SCell，并且为激活的SCell启动第一定时器。
第一定时器被用于在不使用其他的激活/禁用MAC CE的情况下，禁用已经通过激活/禁用MAC CE的方式而激活的相关联的SCell。
此后，每当eNB403通过物理下行链路控制信道（PDCCH）将下行链路或上行链路资源分配给SCell时，用户设备401在步骤411中重新启动第一定时器。
每当从eNB403接收指示SCell的重新激活的激活/禁用MAC CE时，用户设备401在步骤413中重新启动第一定时器。例如，第一定时器是持续与m个帧相对应的时间的定时器。第一定时器可以通过无线资源控制（RRC）层消息的方式来设置。
当下行链路或者上行链路资源没有被分配给SCell，并且在第一定时器期满之前没有接收到指示重新激活SCell的激活/停用MAC CE时，用户设备401在步骤415中启动用于SCell的第二定时器，而没有立即禁用SCell。
第二定时器被用于允许用户设备401用于中断用于SCell的探测参考信号（SRS）的传输和信道质量指示符（CQI）/预编码矩阵索引（PMI）/秩指示符（RI）/预编码器类型指示符（PTI）的传输的时间，以通过在第二定时器期满时禁用SCell而不干扰eNB403的正常操作。将在下面更详细描述CQI/PMI/RI/PTI。
-CQI：对应于满足10％的误码率的推荐的传输格式
-PMI：对应于用于闭环空间复用的索引
-RI：对应于推荐的传输秩
-PTI：对应于编码的指示。
当基站403在第二定时器到期之前，通过PDCCH将下行链路或上行链路资源分配到SCell（例如，UL许可或DL分配）时，用户设备401忽略该分配，并且不会在步骤417中重新启动第一定时器或第二定时器。
在第二定时器启动后，用户设备401可以在第二定时器期满之前中断与eNB403的相互作用不相关的一些操作。例如，用户设备401可以在第二定时器期满之前中断不具有预先设定的中断时间的操作。用户设备401可以中断的这样的操作的示例可以包括：对于来自SCell的PDCCH的监视，以及SRS的传输。
用户设备401可以在第二定时器期满之后，中断与eNB403的相互作用相关的一些操作，以便不干扰eNB403的正常操作。在第二定时器到期之后必须停止的此类操作的示例包括：信道状态信息（CSI）的报告，以及CQI/PMI/RI/PTI的传输。
此后，当第二定时器期满时，用户设备401在步骤419中禁用SCell。在此，第二定时器持续与n个帧相对应的时间，其中n可以是固定的非负整数（例如n=8）。在第二定时器期满后，用户设备401中断关于SCell的SRS和CQI/PMI/RI/PTI的传输。
图5是根据本发明示例性实施例的，例如，根据图4中提供的方法通过用户设备（UE）所执行的过程的流程图。
当包括8位的位图的激活/禁用MAC CE被接收时，用户设备检查是否存在要被激活的SCell，并且，如果这样的SCell存在，则用户设备在步骤501中激活SCell。具体而言，用户设备在接收到激活/禁用MAC CE之前标识禁用的SCell，检查接收的激活/禁用MAC CE的位图，并且在禁用的SCell中激活由位图指示的SCell。激活/禁用MAC CE可以被称为用于确定要激活的SCell的信号。
用户设备在步骤503中，为新激活的SCell启动第一定时器。作为示例，第一定时器的持续时间是可重置的，并且可以在RRC连接重配置过程期间由eNB来设置。用户设备在步骤505中确定下行链路或上行链路资源是否通过PDCCH而被分配到SCell，或者是否接收到指示重新激活SCell的激活/禁用MAC CE。当下行链路或上行链路资源被分配给SCell或者表示重新激活SCell的激活/禁用MAC CE被接收时，用户设备在步骤507中重新启动第一定时器，并且返回到步骤505。否则，当在步骤509中第一定时器期满时，用户设备在步骤511中启动用于SCell的第二定时器。第二定时器的持续时间是固定的，并且不可重置（例如，8帧的时间）。因此，eNB不需要向用户设备通知第二定时器的持续时间，并且持续时间可以在标准中指定。
当第二定时器期满时（例如，当在第一定时器期满后已经过去固定时间时），用户设备在步骤513中禁用SCell，并且中断关于SCell的SRS和CQI/PMI/RI/PTI的传输。对于禁用的SCell，用户设备还中断PDCCH接收。第二定时器启动后，用户设备忽略对于向SCell分配下行链路或上行链路资源的指令。例如，这可以通过在第一定时器期满后，中断SCell的PDCCH监视来实现。也就是说，在第一定时器期满之后，中断SCell的PDCCH监视，并且在第二定时器期满后，中断SRS和CQI/PMI/RI/PTI的传输。
图6是根据本发明示例性实施例的用户设备（UE）的框图。
参照图6，用户设备可以包括收发器单元601、多路复用器/多路解复用（复用器/解复用）单元603、上级层单元605、控制消息处理器607、控制单元609、以及Scell激活器/禁用器611。
在用户设备中，通过上级层单元605来发送和接收数据，并且通过控制消息处理器607来发送和接收控制消息。对于传输而言，在控制单元609的控制下，通过复用/解复用单元603来复用数据，并且通过收发器单元601来发送数据。对于接收而言，在控制单元609的控制下，通过收发器单元601接收的消息信号被通过复用/解复用单元603而解复用，并且根据消息类型，其被转发到上级层单元605或控制消息处理器607。
当接收激活/禁用MAC CE时，控制消息处理器607将其转发到Scell激活器/禁用器611。在控制单元609的控制下，Scell激活器/禁用器611激活由激活/禁用MAC CE所指示的SCell，并且启动第一定时器，以用于新激活的SCell。当下行链路或上行链路资源被分配到SCell或指示Scell的重新激活的激活/禁用MAC CE被接收时，SCell激活器/禁用器611重新启动第一定时器。
此后，当第一定时器期满时，Scell激活器/禁用器611启动用于SCell的第二定时器。在第二定时器启动后，控制单元609可以中断用于下行链路或上行链路的数据传输的、关于SCell的PDCCH接收。当第二定时器期满时，控制单元609中断关于SCell的SRS和CQI/PMI/RI/PTI的传输。
如上所述，根据本发明的示例性实施例，在载波聚合的使用中，通过两个定时器的方式进行特定SCell的禁用。因此，通信可以被准确地执行，同时降低功耗。
根据本发明的特征，所提出的方法能够在不出现错误的情况下成功地完成用于禁用副载波所需的操作。
虽然已参考本发明的若干示例性实施例示出和描述了本发明，但是本领域技术人员应当理解，可以不脱离由所附权利要求及其等同物所定义的本发明的精神和范围的情况下，对本发明在形式和细节上进行各种变化。
