Description

MCS配置指示方法、MCS配置获取方法、基站和用户设备 技术领域
本发明涉及无线通信技术领域。更具体地，本发明涉及由基站执行的MCS配置指示方法、由用户设备执行的MCS配置获取方法以及相应的基站和用户设备。
背景技术
现代无线移动通信系统呈现出两个显著特点，一是宽带高速率，比如第四代无线移动通信系统的带宽可达100MHz，下行速率高达1Gbps；二是移动互联，推动了移动上网、手机视频点播、在线导航等新兴业务。这两个特点对无线移动通信技术提出了较高要求，主要有：超高速率无线传输、区域间干扰抑制、移动中可靠传输信号、分布式/集中式信号处理等等。在未来的增强第四代(4G)及第五代(5G)无线移动通信系统中，为了满足上述发展需求，各种相应的关键技术开始被提出和论证，值得本领域的研究人员广泛关注。
在2007年10月，国际电信联盟(ITU)批准全球微波互联接入系统(WiMax，Worldwide Interoperability for Microwave Access)成为第四个第三代(3G)系统标准。这一发生在3G时代术期的事件，实际上是4G标准争夺战的预演。事实上，为了应对以无线局域网和WiMax为代表的无线互联网协议(IP)技术流的挑战，从2005年开始，第三代伙伴计划3GPP组织就着手进行全新的系统升级，即长期演进系统(LTE，Long Term Evolution)的标准化工作。这是一个基于正交频分复用技术(OFDM，Orthogonal Frequency Division Multiplexing)的准四代系统，已于2009年初推出第一版，并在2010年陆续在全球开始商用。与此同时，3GPP组织关于第四代无线移动通信系统(4G，the Fourth Generation)的标准化制定工作也已经于2008年上半年启动，该系统称为先进的长期演进系统(LTE-A，Long Term Evolution Advanced)。该系统的物理层过程的关键标准化文书已于2011年初完成。在2011年11月ITU组织在中国重庆正式宣布，LTE-A系统和WiMax系统是4G系统的两个官方标准。目前，LTE-A系统的商用过程正在全球范围逐步展开。
根据未来十年的挑战，对于增强的第四代无线移动通信系统，大致有以下几点发展需求：
-更高的无线宽带速率，且重点优化局部的小区热点区域；
-进一步提高用户体验，特别需要优化小区边界区域的通信服务；
-考虑到可用频谱不可能有1000倍的扩展，故需要继续研究能够提高频谱利用效率的新技术；
-高频段的频谱(5GHz，甚至更高)必将投入使用，以获得较大的通信带宽；
-现有网络(2G/3G/4G，WLAN，WiMax等)的协同工作，以分担数据流量；
-针对不同业务、应用和服务特定优化；
-加强系统支持大规模机器通信的能力；
-灵活、智能且廉价的网络规划与布网；
-设计方案以节省网络的用电量和用户设备的电池消耗。
传统的3GPP LTE系统中，单个数据流上是可以发送多个用户数据的，也就是通常所说的多用户(multi-user，简称MU)传输技术。但是，传统的MU技术只有在用户的信道尽可能正交的时候才可以获得更好的性能，这在一定程度上限制了用户调度的灵活性。为此，3GPP RAN#67次全会讨论了一个新的研究课题，即多用户重叠编码(Multi-user Superposition Transmission，简称MUST)的研究，主要目的是研究通过调整多个用户调制信号的功率，以相互重叠叠加的方式来实现单流数据传输多个用户信息的功能。相比于传统的MU技术，多用户重叠编码技术不需要要求用户到基站的信道之间的正交性。因此，采用MUST技术后，基站能够更加灵活的调度用户。目前，3GPP可能会在多媒体广播多播系统(MBMS)中也采用MUST技术。在基本PMCH(basis PMCH，B-PMCH)的基础上，使用MUST技术叠加增强PMCH(enhanced PMCH，E-PMCH)，来达到同时传输多个PMCH的目标。
然而，对于采用MUST技术的PMCH传输，传统的与PMCH传输相关的配置信令可能会遇到如下问题：
-无法指示和获取E-PMCH的MCS配置信息，其具体包括有与E-PMCH对应的MCCH(Multicast Control Channel)的MCS配 置信息以及与E-PMCH对应的MTCH(Multicast Traffic Channel)的MCS配置信息。
因此，针对MUST模式下与PMCH相关的配置信令(例如无线资源控制RRC信令)需要重新设计。
发明内容
针对以上问题，本发明提出了新颖的MCS配置指示和获取方案，以支持采用MUST技术的PMCH传输。
根据本发明的第一方面，提供了一种由基站执行的调制编码方案MCS配置指示方法。所述方法包括：将增强-物理层多播信道E-PMCH的MCS配置信息包括在无线资源控制RRC信令或系统信息块SIB13中，其中，所述E-PMCH采用MUST技术与B-PMCH相叠加；以及向用户设备发送该RRC信令或SIB13。

在步骤s120中，向用户设备发送在步骤s110中产生的RRC信令或SIB13。
通过执行上述MCS配置信息指示方法100，基站可以向用户设备指示E-PMCH的MCS配置信息，从而能够有效地支持采用MUST技术的PMCH传输。
与上述由基站执行的MCS配置指示方法100相对应的，本发明还提出了由用户设备执行的MCS配置获取方法200。如图2所示，方法200包括以下步骤。
步骤s210：从基站接收包括E-PMCH的MCS配置信息的RRC信令或SIB13，其中，所述E-PMCH采用MUST技术与所述B-PMCH相叠加。
步骤s220：从接收到的所述RRC信令或SIB13中提取E-PMCH的MCS配置信息。
如本领域技术人员将意识到的，在方法200中由用户设备从基站接收的RRC信令或SIB13正是在方法100中由基站向用户设备发送的RRC信令或SIB13。
为便于理解，图3进一步示出了根据本发明的实施例的基站和用户设备各自的处理及两者之间的信令交互的序列图。如图所示，首先，在基站侧执行方法100中的步骤s110，将E-PMCH的子帧配置信息包括在RRC信令或系统信息块SIB13中。然后，执行方法100中的步骤s120，向用户设备发送在步骤S110中产生的RRC信令或SIB13。相应地，在用户设备侧执行方法200中的步骤s210，从基站接收包括E-PMCH的子帧配置信息的RRC信令或SIB13。然后，执行步骤s220，从接收到的所述RRC信令或SIB13中提取E-PMCH的子帧配置信息。
图4和图5分别示出了与参照图1和图2描述的由基站执行的MCS配置指示方法和由用户设备执行的MCS配置获取方法相对应的基站400和用户设备500的结构框图。
如图4所示，基站400包括信令处理单元410和收发机420。所述信令处理单元410用于将E-PMCH的MCS配置信息包括在RRC信令或SIB13中。所述收发机420用于向用户设备发送该RRC信令或SIB13。
如图5所示，用户设备500包括收发机510和信令处理单元520。所述收发机510用于从基站接收包括E-PMCH的MCS配置信息的RRC信令或SIB13。所述信令处理单元520用于从接收到的所述RRC信令或SIB13中提取E-PMCH的MCS配置信息。
应该理解，本发明的上述实施例可以通过软件、硬件或者软件和硬件两者的结合来实现。例如，上述实施例中的基站和用户设备内部的各种组件可以通过多种器件来实现，这些器件包括但不限于：模拟电路器件、数字电路器件、数字信号处理(DSP)电路、可编程处理器、专用集成电路(ASIC)、现场可编程门阵列(FPGA)、可编程逻辑器件(CPLD)，等等。
在本申请中，“基站”是指具有较大发射功率和较广覆盖面积的移动通信数据和控制交换中心，包括资源分配调度、数据接收发送等功能。“用户设备”是指用户移动终端，例如包括移动电话、笔记本等可以与基站或者微基站进行无线通信的终端设备。
此外，这里所公开的本发明的实施例可以在计算机程序产品上实现。更具体地，该计算机程序产品是如下的一种产品：具有计算机可读介质，计算机可读介质上编码有计算机程序逻辑，当在计算设备上执行时，该计算机程序逻辑提供相关的操作以实现本发明的上述技术方案。当在计算系统的至少一个处理器上执行时，计算机程序逻辑使得处理器执行本发明实施例所述的操作(方法)。本发明的这种设置典型地提供为设置或编码在例如光介质(例如CD-ROM)、软盘或硬盘等的计算机可读介质上的软件、代码和/或其他数据结构、或者诸如一个或多个ROM或RAM或PROM芯片上的固件或微代码的其他介质、或一个或多个模块中的可下载的软件图像、共享数据库等。软件或固件或这种配置可安装在计算 设备上，以使得计算设备中的一个或多个处理器执行本发明实施例所描述的技术方案。
尽管以上已经结合本发明的优选实施例示出了本发明，但是本领域的技术人员将会理解，在不脱离本发明的精神和范围的情况下，可以对本发明进行各种修改、替换和改变。因此，本发明不应由上述实施例来限定，而应由所附权利要求及其等价物来限定。
