Methods and systems for transmission of multiple modulated signals over wireless networks

A method of allocating uplink (UL) bandwidth on demand in a wireless cellular communication system wherein a wireless cellular mobile unit is registered with, and communicates with a base station, the method comprising:

• determining an amount of pending UL data for a UL connection served by the wireless cellular mobile unit;
• transmitting from the wireless cellular mobile unit a one bit message to the base station requesting to be provided an allocation of UL bandwidth in which to transmit a bandwidth request;
• receiving at the wireless cellular mobile unit the allocation of UL bandwidth in which to transmit the bandwidth request;
• transmitting to the base station, within the allocation of UL bandwidth, the bandwidth request indicative of the amount of UL pending data for the UL connection;
• receiving from the base station an UL bandwidth grant for the wireless cellular mobile unit;
• and
• allocating, at the wireless cellular mobile unit, the UL bandwidth grant to at least two connections served by the wireless cellular mobile unit;
• wherein the wireless cellular mobile unit allocates the UL bandwidth grant to the at least two connections based on a QoS parameter of at least one of the UL connections.
