Downlink communication between a base station and a mobile station occurs in a first format of more than one time slot of a time division multiplexed frame or a second format of one slot per frame when the mobile station performs an uplink transmission using the second format. Single or multiple slot per frame formats can be selected by the mobile station according to whether a high or low rate of data transmission is required. The uplink communication channel may be of the common access type, and both the uplink and downlink slots may be spaced in frequency and spaced in time by less than the duration of one slot. |
