US 6,985,510 B2 · Method and system for data and voice transmission over shared and dedicated channels

Abstract

In one disclosed embodiment, data information is stored in a buffer in a transmitter. The data information is transmitted on a shared channel and control information for recovering the associated data information is transmitted on a dedicated channel. The shared and dedicated channels can be, for example, different portions of the frequency band. The control information can include a spreading factor used to spread the data at the transmitter. For example, the spreading factor can be the length of the Walsh function orthogonal coding used to spread the data. The control information is received over the dedicated channel before the associated data information is received over the shared channel. The control information is then used to recover the associated data information. For example, knowing the spreading factor from the control information, the correct Walsh function can be selected to de-spread, i.e. to Walsh de-cover, the data information.

Dependent claims

A method, comprising:

storing a first frame in a buffer that delays transmission of the first frame on a shared downlink channel, wherein the first frame comprises data information;
transmitting a second frame on a dedicated downlink channel, said second frame comprising at least one slot comprising control information associated with the first frame for recovering said first frame;
and
then transmitting said first frame on the shared downlink channel such that transmission of said first frame is delayed with respect to transmission of the second frame.
