基站可在基站控制器的控制下与终端11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信***可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。

在长期演进(long Term Evolution，LTE)***中，多媒体广播多播业务(Multimedia Broadcast and Multicast Service，MBMS)业务可以通过以下两种方式发送：
MBMS/MBS发送方式1：在MBMS单频网(Multimedia Broadcast multicast service Single Frequency Network，MBSFN)子帧中通过物理多播信道(Physical Multicast Channel，PMCH)发送。其中，控制信息通过***信息(如，SIB13)和广播控制信道(Multicast Control Channel，MCCH)发送，数据通过广播业务信道(Multicast Traffic Channel，MTCH)发送。
MBMS/MBS发送方式2：通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)发送。其中，控制信息通过***信息(如，SIB20)和单小区广播控制信道(Single Cell Multicast Control Channel，SC-MCCH)发送，数据通过单小区广播业务信道(Single Cell Multicast Traffic Channel，SC-MTCH)发送。其中，SC-MCCH通过单小区(Single Cell，SC)-无线网络临时标识(Radio Network Temporary Identity，RNTI)PDCCH调度的PDSCH发送，SC-MTCH通过组(Group，G)-RNTI PDCCH调度的PDSCH发送。
可以给UE配置半持续的数据发送资源，即下行(downlink，DL)半持续调度(Semi-Persistent Scheduling，SPS)，DL SPS由网络侧配置周期性的下行资源，每个周期有1个下行资源分配。网络侧通过PDCCH控制信令激活或去激活该SPS资源的使用
DL SPS对于特定时隙(slot)的混合自动重复请求(Hybrid Automatic Repeat Request，HARQ)进程编号通过以下公式计算得出：
HARQ Process ID＝[floor(CURRENT_slot×10/(numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes
其中，CURRENT_slot为当前的时隙编号。
CURRENT_slot＝[(SFN×numberOfSlotsPerFrame)+slot number in the frame(当前***帧的时隙编号)]。
SFN(System Frame Number)为当前的***帧号。
numberOfSlotsPerFrame为每***帧的时隙数量。
Periodicity为无线资源控制(Radio Resource Control，RRC)消息配置的SPS资源周期。
nrofHARQ-Processes为RRC消息配置的SPS资源的HARQ进程数量。
对于广播多播业务(Multicast Broadcast Service，MBS)的下行数据接收来说，如果采用DCI激活的方式指示可用的资源，该DCI可能在之前已经发送过了，而对于后续才加入的终端(User Equipment，UE)会接收不到DCI，而导致无法知道该下行资源的位置，无法接收到该下行数据。
