PROBLEM TO BE SOLVED: To provide a hybrid transmission method for wireless communications. SOLUTION: A communication channel is divided into a plurality of time slots of equal duration and each of the time slots is further sub-divided into multiple sub-slots. In one embodiment, the communication channel is divided into time slots according to a TDMA (time division multiple access) scheme. Each time slot is then further code-multiplexed into a plurality of sub-slots according to a CDMA (code division multiple access) scheme. Each of the sub- slots is therefore capable of carrying a separately coded transmission within the communication channel, so that multiple simultaneous transmissions can occur in any given time slot.
