Load control in shared medium many-to-one communication systems
First Claim
1. A mobile terminal comprising:
- a receiver;
a transmitter; and
a processor, wherein said receiver is capable of receiving downlink signals generated by and transmitted from a base station and said processor is capable of processing the downlink signals to establish a utilization limitation on a resource that is associated with data which is subsequently transmitted by said transmitter to the base station.

Abstract
A load control method is described herein that enables a base station to broadcast three downlink signals including a busy indicator, a maximum resource indicator and a minimum resource indicator to a mobile terminal. In response to receiving the downlink signals, the mobile terminal limits the utilization of a resource (e.g., bit rate, transmission power, power offset) it uses to transmit data to the base station. The mobile terminal may also send an uplink signal including a resource request to the base station. The base station can use the resource request to change the downlink signals if needed. It is with the proper use of these uplink/downlink signals that the behavior of the base station can be automatically optimized to the load situation.

15. A method for limiting the utilization of a resource used by a mobile terminal to transmit data to a base station in order to optimize and control a load at the base station, said method comprising the steps of:
-
receiving a plurality of downlink signals at said mobile terminal that were transmitted from said base station;
processing the downlink signals to establish a limitation on the use of a resource that is associated with data which is subsequently transmitted from said mobile terminal to said base station;
wherein said resource is a bit rate, transmission power or a power offset where said power offset is a function of power that is distributed between a data channel and a control channel. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
