    • A pilot channel signal for time-division multiplexing with one or more traffic channel signals in a broadcast/multi-cast signal and for code-division multiplexing with a continuously transmitted pilot channel signal is described. In an exemplary method for transmitting a broadcast/multicast signal, a pilot symbol sequence is obtained for each slot of one or more frames of the broadcast/multicast signal, so that the pilot symbol sequence varies for each slot of a given frame. The pilot symbol sequence for each slot is spread with a channelization code, and the spread pilot symbol sequence for each slot is scrambled, using a scrambling code, to form a first pilot channel signal. The first pilot channel signal is transmitted so that it is time-division multiplexed with one or more traffic channel signals transmitted during each slot and code-division multiplexed with a second pilot channel signal transmitted during all slots of the one or more frames.
    • 描述了用于与广播/多播信号中的一个或多个业务信道信号进行时分复用并用于与连续发送的导频信道信号进行码分复用的导频信道信号。 在用于发送广播/多播信号的示例性方法中,为广播/多播信号的一个或多个帧的每个时隙获得导频符号序列,使得导频符号序列对于给定帧的每个时隙而变化。 每个时隙的导频符号序列用信道化码扩展,并且使用扰码对每个时隙的扩展导频符号序列进行加扰,以形成第一导频信道信号。 发送第一导频信道信号,使其与在每个时隙期间发送的一个或多个业务信道信号进行时分复用,并与在一个或多个帧的所有时隙期间发送的第二导频信道进行码分多路复用。
