    • A distributed architecture and method for MBMS delivery is disclosed. The various embodiments enable selection combining and soft combining by UEs for MBMS transmissions. An MBMS service notification (509) is sent to all E-Nodes (503). The E-Nodes proceed to request counting (511) from the UEs (501). A transmission request (513) is then sent to the anchor MBMS-Transmission Control Function (TCF) (505) from the E-Nodes (503). The anchor MBMS-TCF (505) generates resource allocation and scheduling profiles and segmentation and reassembly (SAR) profiles for the E-Nodes and sends the profiles (515) to the E-Nodes. The E-Nodes (503) use the profiles for resource allocation and configuration (517) and transmit MBMS data (519) in accordance with the profiles. The anchor MBMS-TCF (505) may then coordinate.

    • Embodiments include methods and apparatus associated with wireless multicast and/or broadcast services. A base station (102) transmits data codes (504, 604, 702) within a radio frame (300). The data codes are Code Division Multiple Access (CDMA) data codes, in an embodiment. The base station also transmits a Time Division Multiplexed (TDM) synchronization code (502, 608, 706), in an embodiment. The base station discontinuously transmits (1004) a portion of a radio frame slot that is coincident in time with a duration of the TDM synchronization code, in various embodiments. The discontinuously transmitted portion of the radio frame slot may include Transport Format Combination Indicator (TFCI) bits (510), pilot bits (710), or data bits (612), in various embodiments. A base station's transmissions may be synchronous in time and frequency with the transmissions of other base stations.
    • 实施例包括与无线多播和/或广播服务相关联的方法和装置。 基站(102)在无线帧(300)内发送数据码(504,604,702)。 在一个实施例中,数据码是码分多址(CDMA)数据码。 在一个实施例中,基站还发送时分多路复用(TDM)同步码(502,608,706)。 在各种实施例中,基站不连续地发送(1004)与TDM同步码的持续时间在时间​​上重合的无线帧时隙的一部分。 在各种实施例中,无线帧时隙的不连续发送部分可以包括传输格式组合指示符(TFCI)比特(510),导频比特(710)或数据比特(612)。 基站的传输可能与其他基站的传输在时间和频率上同步。
