    • Techniques for supporting broadcast, multicast, and unicast services in a cellular system are described. A Node B may multiplex data for broadcast and multicast services and data for unicast services on radio resources available for transmission. The Node B may periodically send scheduling information used to determine the radio resources carrying the broadcast and multicast services. In one design, the Node B may time division multiplex the data for the broadcast and multicast services and the data for the unicast services. The scheduling information may convey time unit(s) used for each broadcast or multicast service. In another design, the Node B may map the data for the broadcast and multicast services to time frequency blocks. The scheduling information may (i) convey the time frequency block(s) used for each broadcast or multicast service or (ii) point to control information conveying the time frequency block(s) used for each service.
    • 描述了在蜂窝系统中支持广播,多播和单播服务的技术。 节点B可以在可用于传输的无线电资源上复用用于广播和多播服务的数据和用于单播服务的数据。 节点B可以周期性地发送用于确定携带广播和多播服务的无线电资源的调度信息。 在一种设计中,节点B可以对广播和多播服务的数据和单播服务的数据进行时分复用。 调度信息可以传送用于每个广播或多播服务的时间单位。 在另一种设计中,节点B可以将用于广播和多播服务的数据映射到时间频率块。 调度信息可以(i)传送用于每个广播或多播服务的时间频率块,或者(ii)指向用于每个服务的时间频率块的控制信息。
