Description

一种公共消息的传输方法、系统、基站及用户设备 技术领域
本发明涉及通信领域，特别涉及一种公共消息的传输方法、系统、基站及用户设备。
背景技术
公共消息是基站(Evolved NodeB，简称eNB)通知给小区内所有机器类型通信(Machine Type Communication，简称MTC)用户设备(User Equipment，简称UE)的消息。公共消息在高层(higher layer)配置，在物理层传输。物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)用于公共消息的传输，(增强)物理下行控制信道((Enhanced)Physical Downlink Control Channel，简称(E)PDCCH)上的下行控制信息(Downlink Control Information，简称DCI)用于PDSCH的调度。目前，MTC课题提出了如何增强MTC UE覆盖的问题。其中，物理信道的重复发送是增强覆盖的有效技术，具体地，可以重复发送公共消息，以满足覆盖增强的要求。
但是，(E)PDCCH是由整个小区内的MTC UE和非MTC UE共享，同时，考虑到大量MTC UE可能同时接入、以及公共消息在一些场景下可能频繁更新，这些情况将导致小区频谱效率的降低。而对小区频谱效率的影响，在公共消息重复发送的场景下将尤为严重。
针对此，现有技术提供了一种公共消息的获取方法，该方法预先定义好会用来传输公共消息的时频资源、以及公共消息的一些参数，如调制编码方式(Modulation and Coding Schemes，简称MCS)等参数。预先定义的发送公共消息时使用的资源和参数，对eNB和MTC UE都是已知的。eNB不需要发送用于调度PDSCH的DCI，MTC UE在预先定义好的资源上使用约定的参数检测公共消息。
该方法是以完全牺牲eNB的调度灵活度为代价的，对调度灵活性的限制会影响整个小区MTC UE和非MTC UE的资源共享。例如，标准上约定好使用的资源后，这块资源相当于优先分配给了支持MTC业务的MTC UE使用， 而非MTC UE不能更好的灵活使用这些资源。

此外，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集；这样，eNB可以根据信道条件或资源分配情况等，灵活配置UE可以用于盲检测公共消息的传输参数值范围，提高小区资源使用效率和eNB调度资源的灵活度，使得整个小区的资源分配更加灵活高效；同时还抑制UE复杂度以及功耗的提高。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明 实施方式作进一步地详细描述。
为便于理解本发明实施例提供的技术方案，首先对公共消息进行介绍。公共消息包括系统消息、寻呼(Paging)消息和随机接入响应(Random Access Response，简称RAR)消息。系统消息包括主系统信息块(Master Information Block，简称MIB)和系统信息块(System Information Block，简称SIB)。其中，MIB包含系统带宽、系统帧号、以及物理混合自动重传指示信道(Physical Hybrid-ARQ Indicator Channel，简称PHICH)的配置信息。基站(Evolved NodeB，简称eNB)通过物理广播信道(Physical Broadcast Channel，简称PBCH)将MIB广播给小区内所有用户设备(User Equipment，简称UE)。MIB的时频资源是固定的(固定的子帧和固定的子载波)，发送周期也是固定的(发送周期可以是40ms)。
需要说明的是，本实施例不对UE进行限制，UE可以是机器类型通信(Machine Type Communication，简称MTC)UE，即低复杂度地、能处理MTC业务的UE，也可以是除MTC UE之外的其他UE。
实施例一
本发明实施例提供了一种公共消息的传输方法，参见图1，方法流程包括：
步骤101：eNB配置公共消息的传输参数信息。
其中，公共消息的传输参数信息至少包括公共消息的调制编码方式(Modulation and Coding Schemes，简称MCS)指示信息和/或资源块(Resource Block，简称RB)分配指示信息。公共消息包括SIB、RAR消息和Paging消息中的一个或多个。
其中，该MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集。
作为可选的实施方式，该公共消息的传输参数信息还包括子集适用标志，该子集适用标志用于指示，当UE采用子集中的值不能获取公共消息时，UE是否采用子集所属全集中除子集之外的值获取公共消息。
步骤102：eNB通过高层信令将公共消息的传输参数信息下发给UE，并依照公共消息的传输参数信息将公共消息发送给UE。
其中，高层信令可以是开放式通信系统互联参考模型(Open Systems  Interconnection Reference Model)中除了物理层之外的层发出的控制信令，包括SIB和MIB。
步骤103：UE接收eNB下发的高层信令。
步骤104：UE从高层信令中获得公共消息的传输参数信息，并依照传输参数信息获取公共消息。
本发明实施例通过eNB配置公共消息的传输参数信息，通过高层信令将公共消息的传输参数信息下发给UE，UE可以从高层信令中获得公共消息的传输参数信息，这样，eNB不必通过(E)PDCCH上的DCI调度公共消息的传输，UE不需要进行DCI解码，能够降低基于调度方式的公共消息的传输的时延；同时，在重复发送公共消息时，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集，那么，可以通过高层信令发送一次公共消息的传输参数信息，UE可以灵活地采用子集内的值获得重复发送的公共消息；避免了eNB每发一次公共消息，就相应发送一次DCI，而UE每接收一次公共消息，就相应对DCI解码的问题，能够消除采用PDCCH调度公共消息的传输时对小区频谱效率的影响。
此外，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集；这样，eNB可以根据信道条件或资源分配情况等，灵活配置UE可以用于盲检测公共消息的传输参数值范围，提高小区资源使用效率和eNB调度资源的灵活度，使得整个小区的资源分配更加灵活高效；同时还抑制UE复杂度以及功耗的提高。
实施例二～四将分别以传输SIB、RAR消息和Paging消息为例，介绍一种公共消息的传输方法。
实施例二
本发明实施例将以传输SIB为例，介绍一种公共消息的传输方法。
现有协议中，SIB包括多种类型的SIB，例如系统信息块类型1SIB1、系统信息块类型SIB2、系统信息块类型3SIB3等。其中，SIB1由 SystemInformationBlockType1消息承载，其他类型的SIB由系统信息(SystemInformation，简称SI)承载。在本实施例中，SIB可以是现有协议定义的SIB，也可以是未来新定义的SIB。
针对SIB1，SIB1的传输参数信息包括MCS索引号、及虚拟资源块(Virtual Resource Block，简称VRB)的标识(number)。其中，VRB的标识与承载SIB1的物理资源块(Physical Resource Block，简称PRB)的标识一一对应。现有协议规定了SIB1的发送周期，还规定SIB1的传输参数信息由(增强)物理下行控制信道((Enhanced)Physical Downlink Control Channel，简称(E)PDCCH)上的下行控制信息(Downlink Control Information，简称DCI)消息承载。同时，现有协议还规定了传输SIB1的传输参数信息的(E)PDCCH所属子帧的子帧号。UE获得SIB1的过程如下，首先，UE需对指定子帧内所有的(E)PDCCH进行盲检测，直到采用SI-无线网络临时标识(Radio Network Temporary Identity，简称RNTI)在指定子帧内成功解码出某个(E)PDCCH上的DCI，才能获得SIB1的MCS索引号、及VRB的标识。然后，UE根据VRB的标识获得承载SIB1的PRB的标识，进而获得PRB的数量，并根据预置的MCS索引号和PRB的数量两者与传输块大小(Transport Block Size，简称TBS)的对应关系，获得TBS；并获得指定子帧内的物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)上标识与PRB的标识对应的PRB，通过索引号与MCS索引号对应的MCS和TBS解码获得的PRB，得到SIB1。
针对除SIB1之外的其他类型的SIB(下文简称其他类型SIB)，现有协议规定其他类型SIB在各自对应的SI窗口通过动态调度的PDSCH发送。SI窗口包括一个或多个子帧，一个SI窗口对应一个或多个其他类型SIB。参见图2，假设某SI窗口(SI窗口标识为SI-2)包含了5个子帧，其中，第1和2个子帧用于传输SIB3，第4个子帧用于传输SIB4。其他类型SIB的传输参数信息包括，其他类型SIB各自对应的SI窗口包含的子帧数量(即SI窗口的长度)、SI窗口的开始子帧的子帧号(即SI窗口的起始位置)、SI窗口的发送周期、MCS索引号、及VRB的标识。其中，(E)PDCCH上的DCI指示MCS索引号、及VRB的标识；其他类型SIB各自对应的SI窗口包含的子帧数量、SI窗口的开始子帧的子帧号、及SI窗口的发送周期由SIB1指示。UE获得其他类型SIB的过程如下，UE首先解析SIB1，在解析出SIB1后，就获得其他类型SIB各自对应的SI窗口包含的子帧数量、及SI窗口的开始子帧的子帧号。 然后，UE根据所需类型SIB，例如SIB2，所对应的SI窗口包含的子帧数量和开始子帧的子帧号，监听SIB2对应的SI窗口内的每个子帧，并通过SI-RNTI尝试解码每个子帧内的所有(E)PDCCH。假若能成功解码出当前子帧内的某个(E)PDCCH，则说明当前子帧内包含传输SIB2的PDSCH，UE根据解码当前子帧内的(E)PDCCH而获得的MCS索引号、及VRB的标识，进一步获得TBS，并根据相应的MCS和TBS，解码出当前子帧内PDSCH上相应的PRB，获得SIB2。也就是说，eNB未告知UE，其他类型SIB在各自对应的SI窗口中的哪些子帧上传输。这样，UE需要对其他类型SIB各自对应的SI窗口中每个子帧进行盲检测，耗费的时间长，增加了UE的功耗。
基于此，本发明实施例提供了一种公共消息的传输方法，参见图3，该方法流程包括：
步骤201：eNB配置除SIB1之外的其他类型SIB的传输参数信息。
其中，其他类型SIB的传输参数信息包括MCS指示信息和/或RB分配指示信息。
作为可选的实施方式，其他类型SIB的传输参数信息还包括其他类型SIB各自对应的SI窗口包含的子帧数量、SI窗口的开始子帧的子帧号、SI窗口的发送周期中的至少一个。
其中，MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的的子集。
eNB可以采用2bit配置MCS指示信息。当前协议中MCS索引号全集为0～28。考虑到公共消息要求的鲁棒性，未来公共消息可能的调制方式可能为正交相移键控(Quadrature Phase Shift Keying，简称QPSK)/16正交振幅调制(Quadrature Amplitude Modulation，简称QAM)调制的，其MCS索引号全集为0～16。那么，可以预先将0～16划分为16个子集，{0}，{1}，...,{14}和{15}，并与UE约定00用于指示MCS索引号全集的子集{4}，01用于指示MCS索引号全集的子集{5}。还可以预先将0～16划分为4个子集，{0-3}，{4-7}，{8-11}和{12-15}，并与UE约定00用于指示MCS索引号全集的子集{4-7}，或者，约定00用于指示MCS索引号全集的子集{4-7}和{12-16}。
其中，该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的的子集。RB的标识可以是VRB的标识。
作为可选的实施方式，其他类型SIB的传输参数信息还包括TBS指示信 息，该TBS指示信息用于指示预先从TBS全集中划分出的子集。
作为可选的实施方式，其他类型SIB的传输参数信息还包括，承载其他类型SIB的子帧指示信息，该承载其他类型SIB的子帧指示信息用于指示预先从SI窗口的子帧的子帧号全集中划分出的子集。该承载其他类型SIB的子帧指示信息指明了其他类型SIB各自对应的SI窗口中传输对应的其他类型SIB的子帧。
其中，其他类型SIB的传输参数信息还包括子集适用标志，该子集适用标志用于指示当UE采用子集中的值不能获取其他类型SIB时，UE是否采用子集所属全集中除子集之外的值获取其他类型SIB。可以采用1bit配置子集适用标志，比如0指示当UE采用子集中的值不能获取其他类型SIB时，UE采用子集所属全集中除子集之外的值获取其他类型SIB；1指示当UE采用子集中的值不能获取其他类型SIB时，UE不采用子集所属全集中除子集之外的值获取其他类型SIB。
作为可选的实施方式，其他类型SIB传输参数信息还包括，eNB在其他类型SIB各自对应的每个SI窗口的发送周期内重复发送其他类型SIB的次数。例如，假设eNB在SIB2对应的每个SI窗口的发送周期内重复发送SIB2的次数为3，SIB2对应的SI窗口的发送周期为60ms，则，eNB在60ms内将重复发送3次SIB2。重复传输其他类型SIB，可以增加覆盖率。
需要说明的是，其他类型SIB各自对应的SI窗口的大小，即UE接收其他类型SIB尝试解析PDSCH的子帧数量，可以与现有协议规定的SI窗口的大小相同，也可以不同。比如，当其他类型SIB传输参数信息还包括eNB在其他类型SIB各自对应的每个SI窗口的发送周期内重复发送其他类型SIB的次数时，该SI窗口可以包含当前发送周期内发送其他类型SIB的所有子帧。
步骤202：eNB配置SIB1的传输参数信息。
其中，SIB1的传输参数信息包括MCS指示信息和RB分配指示信息中的至少一个。作为可选的实施方式，该MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的的子集。
其中，SIB1的传输参数信息还包括子集适用标志，该子集适用标志用于指示当UE采用子集中的值不能获取SIB1时，UE是否采用子集所属全集中除子集之外的值获取SIB1。
其中，SIB1的传输参数信息还可以包括，eNB在每个SIB1的发送周期内重复发送SIB1的次数。SIB1的发送周期可以是eNB预先与UE约定好的，比如60ms。
作为可选的实施方式，SIB1的传输参数信息还包括TBS指示信息，该TBS指示信息用于指示预先从TBS全集中划分出的子集。例如，该TBS指示信息可以采用2bit来配置。
步骤203：eNB通过MIB将SIB1的传输参数信息发送给UE，通过SIB1将其他类型SIB的传输参数信息发送给UE；分别依照SIB1和其他类型SIB的传输参数信息，将SIB1和其他类型SIB发送给UE。
其中，eNB可以采用MIB中的2bit配置MCS指示信息。
其中，eNB可以采用MIB中的3bit配置RB分配指示信息。
其中，MIB中除了传输协议指定的系统信息以外，还预留了10bit的备用位，保留作他用。eNB可以采用MIB的备用位配置SIB1的传输参数信息。MIB的备用位包括10bit。作为可选的实施方式，可以选用10bit中的6bit配置SIB1的传输参数信息。例如，其中备用位的第1bit(0或1)配置子集适用标志，备用位的第2和第3bit配置MCS指示信息，备用位的第4-6bit配置RB分配指示信息。
其中，eNB发送MIB的方式与现有技术中eNB发送MIB的方式相同，在此不再赘述。此外，eNB是通过PDSCH传输SIB1和其他类型SIB。
步骤204：UE接收eNB下发的MIB。
其中，UE按照现有接收方式接收MIB。
步骤205：UE从MIB中获得SIB1的传输参数信息，并按照SIB1的传输参数信息获取SIB1；从SIB1中获得其他类型SIB的传输参数信息，并按照其他SIB的传输参数信息获取其他类型SIB。
其中，UE获得承载MIB的规定的子帧内PBCH信道上规定的PRB，以获得MIB。从MIB中得到SIB1的传输参数信息，再用SIB1的传输参数信息解码PDSCH，获得SIB1。从SIB1中得到其他类型SIB的传输参数信息，再用其他类型SIB的传输参数信息解码PDSCH，获得其他类型SIB。
假设SIB1的MCS指示信息指示出MCS索引号全集的子集{0-3}，那么UE需要使用索引号分别为0，1，2，或3的MCS尝试盲检测PDSCH。这样，UE只需要最多4次盲检测即可检测出PDSCH。
若SIB1的传输参数信息中子集适用标志指示当UE采用子集中的值不能获取其他类型SIB时，UE采用子集所属全集中除子集之外的值获取其他类型SIB，则，UE先采用子集中的值获取SIB1，若不能获取，再采用子集所属全集中除该子集之外的值获取SIB1。
本发明实施例通过eNB配置公共消息的传输参数信息，通过高层信令将公共消息的传输参数信息下发给UE，UE可以从高层信令中获得公共消息的传输参数信息，这样，eNB不必通过(E)PDCCH上的DCI调度公共消息的传输，UE不需要进行DCI解码，能够降低基于调度方式的公共消息的传输的时延；同时，在重复发送公共消息时，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集，那么，可以通过高层信令发送一次公共消息的传输参数信息，UE可以灵活地采用子集内的值获得重复发送的公共消息；避免了eNB每发一次公共消息，就相应发送一次DCI，而UE每接收一次公共消息，就相应对DCI解码的问题，能够消除采用PDCCH调度公共消息的传输时对小区频谱效率的影响。
此外，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集；这样，eNB可以根据信道条件或资源分配情况等，灵活配置UE可以用于盲检测公共消息的传输参数值范围，提高小区资源使用效率和eNB调度资源的灵活度，使得整个小区的资源分配更加灵活高效；同时还抑制UE复杂度以及功耗的提高。
此外，通过其他类型SIB的传输参数信息还包括承载其他类型SIB的子帧指示信息，该承载其他类型SIB的子帧指示信息用于指示预先从SI窗口的子帧的子帧号全集中划分出的子集，可以减少UE监听SI窗口的时间，降低UE的功耗。
此外，通过子集适用标志的指示，UE可以优先采用子集中的值进行盲检测，并可以在盲检测失败后继续采用全集内除子集之外的值进行盲检测，有一定的灵活性。
实施例三
本发明实施例将以传输RAR消息为例，介绍一种公共消息的传输方法。
RAR消息是UE在随机接入(random access)小区过程中，向eNB发送前导序列(preamble)请求接入后，收到的eNB发送的响应消息，以辅助UE接入此eNB。当前协议中，UE将在一个RAR窗口中接收对应的RAR消息，该RAR窗口的开始子帧的子帧号由协议规定，与UE发送preamble的时刻有关，比如，参见图4，该RAR窗口的开始子帧是preamble所属子帧后面的第3个子帧。其中，RAR消息的传输参数信息包括RAR窗口包含的子帧数量、MCS索引号、及VRB的标识。MCS索引号、及VRB的标识由(E)PDCCH上的DCI承载，该(E)PDCCH位于RAR窗口内的某个子帧内。RAR窗口包含的子帧数量由SIB2指示。
UE获得RAR消息的过程如下，首先，UE在协议规定时刻监听RAR窗口，并在RAR窗口的每个子帧内尝试RAR-RNTI解码每个(E)PDCCH上的DCI，直到成功解码出RAR窗口内当前子帧内的(E)PDCCH，获得RAR的MCS索引号、及VRB的标识。然后，UE根据VRB的标识得到PRB的个数，并根据预置的MCS索引号和PRB个数两者与TBS的对应关系，获得TBS，并根据MCS和TBS解码当前子帧内的PDSCH上相应的PRB，获得RAR消息。也就是说，eNB未告知UE，RAR的传输参数信息及RAR消息在RAR窗口中的哪些子帧上传输。这样，UE需要对RAR窗口中每个子帧进行盲检测，耗费的时间长，增加了UE的功耗。
基于此，本发明实施例提供了一种公共消息的传输方法，参见图5，该方法流程包括：
步骤301：eNB配置RAR消息的传输参数信息。
其中，RAR消息的传输参数信息包括MCS指示信息和RB分配指示信息中的至少一个。该MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集。该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集。
作为可选的实施方式，RAR消息的传输参数信息还包括，RAR窗口包含的子帧数量。
作为可选的实施方式，该RAR消息的传输参数信息还包括承载RAR消息的子帧指示信息，该承载RAR消息的子帧指示信息用于指示预先从RAR窗口的子帧的子帧号全集中划分出的子集。
作为可选的实施方式，RAR的传输参数信息还包括子集适用标志，该子集 适用标志用于指示当UE采用子集中的值不能获取RAR消息时，UE是否采用子集所属全集中除子集之外的值获取RAR消息。
作为可选的实施方式，RAR的传输参数信息还包括eNB在RAR窗口中重复发送RAR消息的次数。
需要说明的是，RAR窗口的大小，即UE接收RAR消息尝试解析PDSCH的子帧数量，可以与现有协议规定的RAR窗口的大小相同，也可以不同。比如，当RAR的传输参数信息还包括eNB在RAR窗口中重复发送RAR消息的次数时，该RAR窗口可以包含当前发送周期内发送RAR消息的所有子帧。
步骤302：eNB通过SIB1或其他类型SIB将RAR的传输参数信息下发给UE，并依照RAR的传输参数信息，将RAR消息发送给UE。
其中，在通过其他类型SIB将RAR的传输参数信息下发给UE时，其他类型SIB可以是除SIB1之外的任何一个SIB，例如SIB2。
步骤303：UE接收eNB下发的SIB1或其他类型SIB。
步骤304：UE从SIB1或其他类型SIB中获得RAR消息的传输参数信息，并按照RAR消息的传输参数信息获取RAR消息。
假若子集适用标志指示当UE采用子集中的值不能获取RAR消息时，UE采用子集所属全集中除子集之外的值获取RAR消息，则UE先采用子集中的值获取RAR消息，若不能获取，再采用子集所属全集中除该子集之外的值获取RAR消息。例如，UE先依照该承载RAR消息的子帧指示信息指示的预先从RAR窗口的子帧的子帧号全集中划分出的子集，优先监听在子集内的RAR窗口中的子帧。假若这些子帧上没有对应的RAR消息，则UE接收RAR失败，不反馈Msg3给eNB，继续在RAR窗口中其他子帧上尝试接收对应的RAR消息，直到成功接收。其中，Msg3是UE发起随机接入过程中，正确接收到eNB发送的Msg2也即RAR消息后，反馈给eNB的建立链接请求的消息。
本发明实施例通过eNB配置公共消息的传输参数信息，通过高层信令将公共消息的传输参数信息下发给UE，UE可以从高层信令中获得公共消息的传输参数信息，这样，eNB不必通过(E)PDCCH上的DCI调度公共消息的传输，UE不需要进行DCI解码，能够降低基于调度方式的公共消息的传输的时延；同时，在重复发送公共消息时，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集，那么，可以通过高层信令发送一 次公共消息的传输参数信息，UE可以灵活地采用子集内的值获得重复发送的公共消息；避免了eNB每发一次公共消息，就相应发送一次DCI，而UE每接收一次公共消息，就相应对DCI解码的问题，能够消除采用PDCCH调度公共消息的传输时对小区频谱效率的影响。
此外，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集；这样，eNB可以根据信道条件或资源分配情况等，灵活配置UE可以用于盲检测公共消息的传输参数值范围，提高小区资源使用效率和eNB调度资源的灵活度，使得整个小区的资源分配更加灵活高效；同时还抑制UE复杂度以及功耗的提高。
此外，通过该RAR消息的传输参数信息还包括承载RAR消息的子帧指示信息，该承载RAR消息的子帧指示信息用于指示预先从RAR窗口的子帧的子帧号全集中划分出的子集，可以减少UE监听RAR窗口的时间，降低UE的功耗。
此外，通过子集适用标志的指示，UE可以优先采用子集中的值进行盲检测，并可以在盲检测失败后继续采用全集内除子集之外的值进行盲检测，有一定的灵活性。
实施例四
本发明实施例将以传输寻呼(Paging)消息为例，介绍一种公共消息的传输方法。
Paging消息可由核心网触发，用于通知某个UE接受寻呼请求，或者由eNB触发，通知UE系统信息的更新。当前协议中，UE通常只在指定时刻醒来，监听(E)PDCCH以便获得传输Paging消息的MCS索引号、及RB的标识。该指定时刻由UE的ID、Paging的发送周期和参数nB决定。Paging的发送周期和参数nB由SIB2配置。该指定时刻接收的子帧称为寻呼时刻(Paging Occasion，简称PO)，即是可能含有UE对应的Paging消息的子帧。如果检测到PO内(E)PDCCH上的DCI由P-RNTI加扰，则说明在该PO内UE需要检测由该DCI调度的PDSCH上承载的paging消息；反之，假若无法检测该DCI，则说明该PO内未传输Paging消息。Paging的传输参数信息包括MCS索引号、RB的标识、Paging消息的发送周期和参数nB。
基于此，本发明实施例提供了一种公共消息的传输方法，参见图6，该方法流程包括：
步骤401：eNB配置Paging消息的传输参数信息。
作为可选的实施方式，配置Paging消息的传输参数信息的SIB不是配置RAR消息的传输参数信息的SIB。
其中，Paging消息的传输参数信息包括MCS指示信息和/或RB分配指示信息。作为可选的实施方式，该MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集。该RB分配指示信息是一个或多个预先从RB标识全集中划分出的子集。
作为可选的实施方式，Paging消息的传输参数信息还包括Paging消息的发送周期和参数nB中的至少一个。
作为可选的实施方式，该Paging消息的传输参数信息还包括承载Paging消息的子帧指示信息，该承载Paging消息的子帧指示信息用于指示预先从PO的子帧号全集中划分出的子集。
作为可选的实施方式，该Paging消息的传输参数信息还包括eNB在每个Paging消息的发送周期内重复发送Paging消息的次数。
其中，Paging消息的传输参数信息还包括子集适用标志，该子集适用标志用于指示当UE采用子集中的值不能获取Paging消息时，UE是否采用子集所属全集中除子集之外的值获取Paging消息。
步骤402：eNB通过SIB1或其他类型SIB将Paging消息的传输参数信息下发给UE，并依照Paging消息的传输参数信息，将Paging消息发送给UE。
其中，在通过其他类型SIB将Paging消息的传输参数信息下发给UE时，其他类型SIB可以是除SIB1之外的任何一个SIB，例如SIB3。
步骤403：UE接收eNB下发的SIB1或其他类型SIB。
步骤404：UE从SIB1或其他类型SIB中获得Paging消息的传输参数信息，并按照Paging消息的传输参数信息获取Paging消息。
假若子集适用标志指示当UE采用子集中的值不能获取Paging消息时，UE不采用子集所属全集中除子集之外的值获取Paging消息，则UE仅采用子集中的值获取Paging消息。例如，UE依照承载Paging消息的子帧指示信息，监听承载Paging消息的子帧。假若这些子帧上没有对应的Paging消息，则UE接收Paging失败，UE已有的系统消息将不更新。
本发明实施例通过eNB配置公共消息的传输参数信息，通过高层信令将公共消息的传输参数信息下发给UE，UE可以从高层信令中获得公共消息的传输参数信息，这样，eNB不必通过(E)PDCCH上的DCI调度公共消息的传输，UE不需要进行DCI解码，能够降低基于调度方式的公共消息的传输的时延；同时，在重复发送公共消息时，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集，那么，可以通过高层信令发送一次公共消息的传输参数信息，UE可以灵活地采用子集内的值获得重复发送的公共消息；避免了eNB每发一次公共消息，就相应发送一次DCI，而UE每接收一次公共消息，就相应对DCI解码的问题，能够消除采用PDCCH调度公共消息的传输时对小区频谱效率的影响。
此外，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集；这样，eNB可以根据信道条件或资源分配情况等，灵活配置UE可以用于盲检测公共消息的传输参数值范围，提高小区资源使用效率和eNB调度资源的灵活度，使得整个小区的资源分配更加灵活高效；同时还抑制UE复杂度以及功耗的提高。
此外，通过该Paging消息的传输参数信息还包括承载Paging消息的子帧指示信息，该承载Paging消息的子帧指示信息用于指示预先从PO的子帧号全集中划分出的子集，可以减少UE监听PO的时间，降低UE的功耗。
此外，通过子集适用标志的指示，UE可以优先采用子集中的值进行盲检测，并可以在盲检测失败后不再盲检测，有一定的灵活性；有利于减少UE在激活态的工作时间，降低UE的功耗。

实施例十一
参见图11，本发明实施例提供了一种公共消息的传输系统，该系统包括基站1101和用户设备1102。
其中，基站1101的结构与实施例五、六或九提供的基站的结构相同；用户设备1102的结构与实施例七、八或十提供的用户设备的结构相同，在此不再赘述。
本发明实施例通过eNB配置公共消息的传输参数信息，通过高层信令将公共消息的传输参数信息下发给UE，UE可以从高层信令中获得公共消息的传输参数信息，这样，eNB不必通过(E)PDCCH上的DCI调度公共消息的传输，UE不需要进行DCI解码，能够降低基于调度方式的公共消息的传输的时延；同时，在重复发送公共消息时，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集，那么，可以通过高层信令发送一次公共消息的传输参数信息，UE可以灵活地采用子集内的值获得重复发送的公共消息；避免了eNB每发一次公共消息，就相应发送一次DCI，而UE每接收一次公共消息，就相应对DCI解码的问题，能够消除采用PDCCH调度公共消息的传输时对小区频谱效率的影响。
此外，由于MCS指示信息用于指示一个或多个预先从MCS索引号全集中 划分出的子集；该RB分配指示信息用于指示一个或多个预先从RB标识全集中划分出的子集；这样，eNB可以根据信道条件或资源分配情况等，灵活配置UE可以用于盲检测公共消息的传输参数值范围，提高小区资源使用效率和eNB调度资源的灵活度，使得整个小区的资源分配更加灵活高效；同时还抑制UE复杂度以及功耗的提高。
需要说明的是：上述实施例提供的基站或用户设备在传输公共消息时，仅以上述各功能模块的划分进行举例说明，实际应用中，可以根据需要而将上述功能分配由不同的功能模块完成，即将基站或用户设备的内部结构划分成不同的功能模块，以完成以上描述的全部或者部分功能。另外，上述实施例提供的基站或用户设备与公共消息的传输方法实施例属于同一构思，其具体实现过程详见方法实施例，这里不再赘述。
上述本发明实施例序号仅仅为了描述，不代表实施例的优劣。
本领域普通技术人员可以理解实现上述实施例的全部或部分步骤可以通过硬件来完成，也可以通过程序来指令相关的硬件完成，所述的程序可以存储于一种计算机可读存储介质中，上述提到的存储介质可以是只读存储器，磁盘或光盘等。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
