102, 向服务的用户终端发送所述 MBSFN子帧中 PRB用途的指示信息。 具体的, 基站在接收 MCE发送的用于指示 MBSFN子帧中 PRB用途的指 示信息后, 向服务的用户终端发送所述 MBSFN子帧中 PRB用途的指示信息, 其中, 所述用于指示 MBSFN子帧中 PRB用途的指示信息包括:
指示 MBSFN子帧中应用于 eCCH的 PRB的指示信息;
其中, 所述 MBSFN 子帧中应用于 eCCH 的 PRB 的指示信息用于指示 MBSFN子帧里应用于 eCCH的 PRB个数和 /或位置; 或

步骤 102, 向服务的用户终端发送所述 MBSFN子帧中 PRB用途的指示信 息包括:
通过广播信令向服务的用户终端指示信息, 所述指示信息用于指示所述 MBSFN子帧中 PRB用途的指示信息; 或
通过广播信令和专用信令向服务的用户终端发送指示信息, 所述指示信息 用于指示所述 MBSFN子帧中 PRB用途的指示信息; 或
通过专用信令向服务的用户终端发送指示信息, 所述指示信息用于指示所 述 MBSFN子帧中 PRB用途的指示信息。
本实施例中基站接收 MCE发送的用于指示 MBSFN子帧中 PRB用途的指 示信息之后,向服务的用户终端发送所述 MBSFN子帧中 PRB用途的指示信息, 以便用户终端根据接收到的指示信息正确解读 MBMS和 eCCH。
参见图 2, 本发明提供的一种物理资源块 PRB的指示方法的第一种具体实 现方式, 所述方法包括:
201 , 接收用于指示 MBSFN子帧中应用于 eCCH的 PRB的指示信息。
具体的, 当基站接收 MCE发送的用于指示 MBSFN子帧中 PRB用途的指 示信息为指示 MBSFN子帧中应用于 eCCH的 PRB时, 通过多媒体广播组播业 务控制信道( MBMS Control Channel, MCCH )或者***消息 SIB13向服务的用 户终端发送所述 MBSFN子帧中应用于 eCCH的 PRB的指示信息, 其中, 所述 MBSFN子帧中应用于 eCCH的 PRB的指示信息用于指示 MBSFN子帧中应用 于 eCCH的 PRB个数和 /或位置。
202,向服务的用户终端发送所述 MBSFN子帧中应用于 eCCH的 PRB的指 示信息。
具体的,通常 MBSFN子帧中所有的 PRB都是默认用来发送 MBMS的,但 基站在接收用于指示 MBSFN子帧中应用于 eCCH的 PRB的指示信息时, 基站 通过广播信令 MCCH或者 SIB13将所述 MBSFN子帧中应用于 eCCH的 PRB的 指示信息发送给用户终端,以便用户终端根据上述基站广播的 MCCH或者 SIB13 消息, 在 MBSFN子帧中应用于 eCCH的 PRB的指示信息中解读 eCCH。 同时,
用户终端根据上述基站广播的 MCCH或者 SIB13消息, 在 MBSFN子帧中与上 述应用于 eCCH的 PRB不同的 PRB中读取 MBMS数据。
举例来说, 本实施例提到的用于指示 MBSFN子帧中应用于 eCCH的 PRB 的指示信息的方法,可以是一个比特流,其中第 n个比特对应于 MBSFN子帧中 的第 n个 PRB, 1表示该 PRB用于 eCCH (即不用于 MBMS ) , 0表示该 PRB 不用于 PRB (即用于 MBMS ); 或者也可以反过来, 0表示用于 eCCH (即不用 于 MBMS ) , 1表示不用于 eCCH (即用于 MBMS ) 。 这个比特流中 1或者 0 的个数, 隐含了用于 eCCH的 PRB的个数, 也可以直接是用于 eCCH的 PRB的 个数。
需要说明的是, 在本实施例中, 同一个 MBSFN Area内的所有基站下用于 eCCH的 PRB的个数或位置都相同。
参见图 3 , 本发明提供的一种物理资源块 PRB的指示方法第二种具体实现 方式, 所述方法包括:
301 , 接收用于指示 MBSFN子帧中不应用于 MBMS传输的 PRB的指示信 息。
具体的, 当基站接收的用于指示 MBSFN子帧中 PRB用途的指示信息为指 示 MBSFN子帧中不应用于 MBMS传输时, 通过广播信令 MCCH或者 SIB13 向服务的用户终端发送所述 MBSFN子帧中不应用于 MBMS传输的 PRB的指示 信息, 其中, 所述 MBSFN子帧中不应用于 MBMS传输的 PRB的指示信息用于 指示 MBSFN子帧中不应用于 MBMS传输的 PRB个数和 /或位置。
进一步的, 当基站接收的用于指示 MBSFN子帧中 PRB用途的指示信息为 指示 MBSFN子帧中不应用于 MBMS传输的 PRB时, 由于 MBSFN子帧中不应 用于 MBMS传输的 PRB, 是可能应用于 eCCH, 也可能用于其它用途, 它们是 相关 MBSFN区域内 MBSFN子帧里所有可能应用于 eCCH的 PRB的一个父集 合,对于一个特定的用户终端来说,应用于 eCCH的 PRB可能是它的一个子集。 因此,基站通过广播信令 MCCH或者 SIB13将 MBSFN子帧中不应用于 MBMS 传输的 PRB的指示信息发送给用户终端的同时, 基站还通过专用信令, 如无线 资源控制协议( Radio Resource Control, RRC )信令将 MBSFN子帧中应用 eCCH 的 PRB的指示信息发送给一个特定的用户终端, 以便该特定的用户终端在上述 专用信令指示的 PRB里面读取 eCCH。
