First Claim
Patent Images
1. A method for scheduling uplink dedicated channels at a wireless network, comprising:
- transmitting, from a network node, a scheduling grant message to trigger uplink transmissions, the scheduling grant message starting in any time slot of a frame for a downlink channel, the scheduling grant message not exceeding the length of the frame, the scheduling grant message starting time slot capable of varying from frame to frame, andconducting a blind detection to determine the starting time slot of the scheduling grant message.

Abstract
In the scheduling method of the present invention, scheduling grant messages for a user equipment are transmitted beginning in any time slot of a frame for a channel so long as the scheduling grant message does not exceed the frame. The scheduling grant message indicates user equipment is approved to transmit on an uplink dedicated channel. This downlink transmission and subsequent uplink dedicated channel transmission have a timing relationship such that no more than one user equipment will begin transmitting on a respective uplink dedicated channel at a time.
