Abstract: Transmission methods for multicast messages and for signaling message responses thereto in communication systems supporting a multicast mode provide that a number of retransmissions of a multicast message may be changed based on a number of receivers (105) of the message. Signaling messages to the multicast message may be transmitted in response to a fixed number of multicast message transmissions, and receivers (105) that have not received the multicast message after the fixed number of transmissions may request further retransmissions up to an additional given number of times. Further, signaling messages may be transmitted at different times or staggered based on a radio condition of the receivers (105). For example, a first multicast message may be transmitted, and responses from groups of receivers (105) may be listened to for a given period, after which one of a next multicast message and a portion of the first multicast message may be transmitted to the groups.

Abstract translation: 在支持多播模式的通信系统中用于多播消息和用于向其发送信令消息响应的传输方法提供了可以基于消息的多个接收器（105）来改变多播消息的重传次数。 对组播消息的信令消息可以响应于固定数量的组播消息传输而被发送，并且在固定次数的传输之后尚未接收到组播消息的接收机（105）可以请求进一步的重新传输达到额外的给定次数 。 此外，信令消息可以在不同的时间被发送或者基于接收器（105）的无线电条件而被交错。 例如，可以发送第一多播消息，并且可以在给定的时间段内收听来自多组接收器（105）的响应，之后可以将下一个多播消息和第一多播消息的一部分中的一个发送给 组。
