摘要：
A communication device (e.g., 106) having multiple transmission modes employs a method of transmitting user information (309, 310) and intermittent overhead data (307, 308). The communication device (106) selects from a first transmission technique and a second transmission technique. When the first transmission technique is selected and overhead data (307) is to be transmitted, the communication device (106) replaces a first predetermined amount of the user information (309) with the overhead data (307) to form a data unit. When the second transmission technique is selected and overhead data (308) is to be transmitted, the communication device (106) replaces a second predetermined amount of the user information (310) with the overhead data (308) to form the data unit, wherein the second predetermined amount is less than the first predetermined amount. The communication device (106) then transmits the data unit formed by either transmission technique, such that when using the second transmission technique, an increased number of bits (506) are available over time to represent the user information, while a substantially equal number of bits (508) are available over time to represent the overhead data as compared to the first transmission technique.
