METHOD FOR TRANSMITTING CONTROL INFORMATION ON THE FORWARD LINK OF A WIRELESS NETWORK |
摘要 |
A signaling method is provided that can improve the efficiency of forward-link control signaling in OFDM systems. The method involves using a set of forward-link subcarriers that are dedicated for control information, and are shared by a set of two or more users. The control information destined for each user is spread using a respective spreading code, thereby to provide a spread control message. The spread control messages destined for the various users are summed together prior to transmission. |
