METHOD AND APPARATUS FOR DYNAMIC TIME SLOT ALLOCATION
First Claim
1. A method for dynamic allocation of a downlink time slot comprising:
- allocating a first downlink time slot to a mobile station;
subsequent to allocating the first time slot, determining that a second downlink time slot is available for allocation, wherein the second time slot is different from the first time slot;
allocating the second downlink time slot to the mobile station; and
informing the mobile station of the allocation of the second downlink time slot via a Downlink Radio Link Control (RLC) data block.

Abstract
A communication system utilizes a Downlink Radio Link Control (RLC) data block conveyed to a mobile station (MS) via a first downlink time slot to inform the MS of an allocation of a second downlink time slot, which Downlink RLC data block is conveyed to the MS regardless of the allocation. By utilizing the Downlink RLC data block, the communication system informs the MS of the dynamically allocated time slot without the specialized messages of, and the additional bandwidth consumed by, the prior art. Furthermore, when the first downlink time slot comprises a bearer channel already allocated to the MS, the system then provides for in-band signaling of the MS of the newly allocated time slot.

23. A method for in-band signaling of a time slot allocation comprising:
-
allocating a bearer channel to a mobile station, wherein the bearer channel comprises a first downlink time slot to a mobile station;
subsequent to allocating the bearer channel, determining that a second downlink time slot is available for allocation, wherein the second time slot is different from the first time slot;
allocating the second downlink time slot to the mobile station; and
informing the mobile station of the allocation of the second downlink time slot via the bearer channel.
