ABSTRACT:
Embodiments include methods and apparatus associated with wireless multicast and/or broadcast services. A base station (102, FIG.1) transmits data codes (504, 604, 702, FIGS.5-7) within a radio frame (300, FIG.3). 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, FIGS.5-7), in an embodiment. The base station discontinuously transmits (1004, FIG.10) 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, FIG.5), pilot bits (710, FIG.7), or data bits (612, FIG.6), in various embodiments. A base station's transmissions may be synchronous in time and frequency with the transmissions of other base stations.
