    • Techniques for supporting multimedia broadcast/multicast services (MBMS) are described. A group of base stations/cells may support a number of MBMS services and may transmit any set of MBMS services in a given scheduling period. In one design, a base station may determine scheduling information for a plurality of MBMS services, generate a bitmap based on the scheduling information, and send the bitmap to convey the scheduling information. The bitmap may include a bit for each MBMS service, and the bit may indicate whether or not that MBMS service is scheduled. In one design, the bitmap may cover all MBMS services supported by the base station. In another design, a plurality of groups of MBMS services may be formed for all supported MBMS services. A group of MBMS services may be selected from among the plurality of groups, and the bitmap may be for the MBMS services in the selected group.
    • 描述了用于支持多媒体广播/多播服务(MBMS)的技术。 一组基站/小区可以支持多个MBMS服务,并且可以在给定的调度周期内发送任何MBMS业务集合。 在一种设计中,基站可以确定多个MBMS服务的调度信息,基于调度信息生成位图,并发送位图以传送调度信息。 位图可以包括每个MBMS服务的位,并且该位可以指示该MBMS服务是否被调度。 在一种设计中,位图可以覆盖由基站支持的所有MBMS服务。 在另一种设计中,可以为所有支持的MBMS服务形成多组MBMS服务。 可以从多个组中选择一组MBMS服务,并且位图可以针对所选择的组中的MBMS服务。
