Method and apparatus for fast data rate ramp up in Node B scheduling of UE uplink
First Claim
1. A method by which a user equipment device configured for wireless communication with a node of a wireless communication system is instructed to adjust the value of a data rate pointer maintained in the user equipment device, the data rate pointer indicating a maximum allowed data rate available to the user equipment for uplink transmission of data to the node, the method comprising:
- the issuing to the user equipment device a pointer change command in response to a change request by the user equipment device, the node issuing the change command based on predetermined rules; and
the user equipment device adjusting the data rate pointer according to the change command and based on predetermined rules for interpreting the change command;
wherein the predetermined rules used by the node in responding to the change request differ depending on the current value of the data rate pointer.

Abstract
A method and corresponding equipment for communicating from a Node B (10) to a UE device (11) a data rate pointer (11a) value indicating a new maximum allowed data rate in case of a current low value for the data rate pointer (11a), based on predetermined rules governing signaling to change the data rate pointer and used by the Node B (10) in responding to a change request from the UE device (11), rules that differ for different current values of the data rate pointer (11a), and in particular rules that allow for a fast ramp up in case of a current value of zero or less than a threshold.
