Abstract
Each of groups each has a plurality of communication channels. There are generated signals to be transmitted via the respective communication channels in the groups. The transmitted signals are time-division-multiplexed into a data sequence for each of the groups. The data sequences are spectrum-spread in response to different spread code patterns respectively. A reserve time slot may be provided. In cases where a reduction of a received signal quality related to one of the communication channels is detected, the reserve time slot is used in transmitting the signal of said one of the communication channels.
