Description

媒体接入控制层处理方法及装置 技术领域
本文涉及但不限于通信领域，具体而言，涉及一种媒体接入控制层处理方法及装置。
背景技术
1、多媒体广播多播业务MBMS介绍
长期演进LTE(Long Term Evolution)中的MBMS又被称为eMBMS(evolved MBMS)，主要功能是在LTE系统中实现广播和多播业务。目前MBMS主要通过混合小区实现，即传输MBMS业务的小区同时也传输单播业务。而多个MBMS小区可以组成一个多媒体广播多播业务单频网络MBSFN(Multimedia Broadcast multicast service Single Frequency Network)区域，在同一MBSFN内广播相同的MBMS业务。而具备载波聚合CA(Carrier Aggregation)能力的用户终端UE是可以在SCell上接收MBMS的，并需要在接收MBMS的SCell上接收对应的系统信息和系统信息变更通知。
对于有载波聚合能力的UE，UE能够同时在多个频点进行单播业务的收发。因此UE也需要能够在多个频点进行MBMS业务的接收，而接收MBMS业务的频点并不需要是UE的服务频点，对于空闲态(IDLE)UE来说其服务频点是该UE的驻留频点，对于连接态UE来说该服务频点是网络给UE配置的工作频点。当UE发现其感兴趣的MBMS频点并非是其服务频点的时候，UE需要能够将该非服务频点自行配置来接收MBMS业务。而对于UE来说，该自配置频点(或自配置SCell)和其他服务频点的工作方式是一样的，UE需要接受系统信息和系统信息的变更，以及MBMS相关的控制信息。
eMBMS相关控制信息包括：
(1)系统信息：
SIB13，广播的是当前小区下所属的每个MBSFN的基础配置信息，包括 每个MBSFN对应的逻辑控制信道MCCH的配置，以及该MCCH变更通知的配置。
SIB15，广播的是MBMS业务连续性相关的信息，给出了每个MBMS频点(包括当前小区频点和邻频点)对应的服务区标识码SAI(Service Area Identity)信息。用以辅助RRC_IDLE和RRC_CONNECTED UE找到其感兴趣的MBMS频点，从而在移动过程中保证MBMS业务的连续接收。对于RRC_IDLE来说，可能会将SIB15其感兴趣的MBMS频点设置为高优先级频点，以便于接收MBMS业务。
(2)逻辑信道多播控制信道MCCH(Multicast Control Channel)：
多播控制信道，是一个点到多点(point-to-multipoint)的下行信道，用于网络向UE传输MBMS相关的控制信息以及用于统计MBMS业务兴趣的counting(统计)信息，一个MCCH可以对应于一个或多个多播业务信道MTCH；该信道只有能接收MBMS业务的UE才可以使用。基站会将MCCH的修改周期和重复周期通过系统广播通知UE，修改周期一般是重复周期的X(X为非0偶数，如2,4等)倍，在一个修改周期内，所有重复周期发送的MCCH信息是一样的，这是为了保证MCCH的可靠接收。同时MCCH内信息的变更是在物理层下行控制信道PDCCH(Physical Downlink Control Channel)中通过多播-无线网络临时标识M-RNTI(Multicast-Radio Network Temporary Identity)加扰的bit位指示的。UE在获取到MCCH的变更通知后，需要重新读取该MCCH。
(3)eMBMS的MAC调度控制，多播信道MCH调度信息MSI(MCH Scheduling Information)MAC CE(Control Element，控制元素):
MSI是作为MAC层的控制信令，在每个MCH调度周期MSP(MCH Scheduling Period)的第一个子帧中传输，用于指示每一个MTCH的位置和当前MCH中没有被使用的子帧。
(4)逻辑信道MTCH(Multicast Traffic Channel)：
多播业务信道，是一个点到多点的下行信道，用于网络向UE传输MBMS业务数据；该信道只有能接收MBMS业务的UE才可以使用。MTCH的配置 信息是由其对应的MCCH指示的。网络利用MCCH向UE指示MTCH，从而达到使UE接收在MTCH上承载的MBMS业务的目的。
(5)传输信道MCH(Multicast Channel)和物理信道PMCH(Physical Multicast Channel)：
MCCH和MTCH均映射到MCH上进行传输，而MCH再映射到PMCH上进行传输。每个MCH在一个MCH调度周期中进行发送，MCH的调度周期即MSP(MCH Scheduling Period)。
2、SC-PTM技术介绍
当在单个小区中发送MBMS业务的时候，为了提高资源利用的效率，将MBMS业务通过动态调度的方式在单播通讯的物理下行共享信道PDSCH(Physical Downlink Shared Channel)中发送。SC-PTM的传输仍然需要对应的控制信道(如SC-MCCH，Single Cell MCCH)和数据信道(如SC-MTCH，Single Cell MTCH)。且控制信道和数据信道分别通过不同的物理信道传输。
3、MAC功能介绍
当前MAC PDU中包含以下几个单元：
(1)MAC header:设置为指示MAC PDU中所包含的MAC CE；MAC SDU；Padding的位置。
(2)MAC CE(Control Element):设置为发送MAC层的控制信息。
(3)MAC SDU：设置为承载高层的数据包，包含来自不同逻辑信道的信息。
(4)Padding:设置为当MAC的信息和数据部分大小之和无法满足底层指示传输块大小的时候，增加的额外冗余信息。
当前用于下行共享信道DL-SCH(Downlink Shared channel)和多播信道MCH(Multicast channel)的MAC PDU如图1所示：MAC层为了确保控制信息和来自高层的数据能够在同一个MAC PDU中传输，为控制信息和不同的高层实体分配了对应的逻辑信道号(LCID,Logical Channel ID)，用以区分控制信息和不同的高层实体数据。
相关技术中，在SC-PTM下，MAC层如何划分逻辑信道才能最有效的将 尽量多的控制信息和数据复用在同一个MAC PDU中还没有确定。

通过本发明实施例，采用MAC层将SC-PTM的控制信道信息和数据信道信息设置在不同的MAC PDU中，由于逻辑信道的数量有限，相同MAC PDU中逻辑信道号不能重复，因此将逻辑信道信息(所述逻辑信道信息通常分为两类：控制信道信息、数据信道信息)设置在不同的MAC PDU中，可以更有利于其他信息同SC-PTM的控制信道信息复用同一个MAC PDU，或 者同SC-PTM的数据信道信息复用同一个MAC PDU，达到了在SC-PTM下，更有效的利用可用的逻辑信道号，将尽量多的控制信息和数据信息复用在同一个MAC PDU的效果。
