    • A base station generates per-cell ACK/NACK responses rather than per-sector ACK/NACK responses. For a given mobile station signal received in softer handoff at two of the base station's sectors, the base station generates an ACK response if at least one of the soft handoff sectors correctly receives the signal, and otherwise generates a NACK response. Alternatively, the base station can combine the softer handoff signals and generate ACK/NACK responses based on whether the combined signal is correctly received. Since only one set of ACK/NACK responses are generated for all of the softer handoff sectors, the base station can use the forward link in just one softer handoff sector to send the ACK/NACK responses to the mobile station, consuming fewer forward link transmit resources at the base station. Or, the base station can send the same ACK/NACK responses from two or more softer handoff sectors, thus allowing diversity combining of the ACK/NACK responses at the mobile station.
    • 基站产生每小区ACK / NACK响应而不是每扇区ACK / NACK响应。 对于在两个基站扇区的较软切换中接收到的给定移动站信号,如果软切换扇区中的至少一个正确地接收到该信号,则基站产生ACK响应,否则产生NACK响应。 或者,基站可以组合较软切换信号,并且基于组合信号是否被正确接收来生成ACK / NACK响应。 由于仅为所有更软切换扇区生成一组ACK / NACK响应,所以基站可以在仅一个较软切换扇区中使用前向链路来向移动台发送ACK / NACK响应,从而消耗较少的前向链路传输 资源在基站。 或者,基站可以从两个或更多个更软切换扇区发送相同的ACK / NACK响应,从而允许在移动站处的ACK / NACK响应的分集组合。
