    • A method and system for providing asymmetric modes of operation in multi-carrier wireless communication systems. A method may assign a long code mask (LCM) to an information channel associated with a plurality of forward link carriers to transmit data from an access network to an access terminal; and multiplex the information channel on a reverse link carrier. The information channel may include one of data source channel (DSC), data rate control (DRC) and acknowledgment (ACK) information, and the multiplexing may be code division multiplexing (CDM). The AN may instruct the AT on whether to multiplex the DSC information based on feedback from the AT. The method may further offset the ACK information on the reverse link to reduce the reverse link peak to average, CDM the information channel on an I-branch and on a Q-branch, and transmit the code division multiplexed information channel on the reverse link carrier.
    • 一种用于在多载波无线通信系统中提供不对称操作模式的方法和系统。 方法可以将长码掩码(LCM)分配给与多个前向链路载波相关联的信息信道,以将数据从接入网络传输到接入终端; 并在反向链路载波上复用信息信道。 信息信道可以包括数据源信道(DSC),数据速率控制(DRC)和确认(ACK)信息之一,并且复用可以是码分复用(CDM)。 AN可以根据AT的反馈来指示AT是否复用DSC信息。 该方法还可以抵消反向链路上的ACK信息,以减少反向链路峰值平均,CDM在I分支和Q分支上的信道,并在反向链路载波上发送码分多路复用信息信道 。
