Radio resource management for a high speed shared channel
First Claim
1. A method for a mobile communications network supporting mobile radio communication using plural radio channels associated with a radio base station including first radio channels and a high speed shared radio channel, comprising:
- the radio base station measuring one or more parameters that affect management of the high speed shared radio channel;
the radio base station reporting one or more of the measured parameters to a radio resource controller; and
the radio resource controller using the measured parameters to efficiently use radio resources associated with the high speed shared radio channel.

Abstract
Radio resources like spreading codes and transmission power are optimally allocated to various different types of radio channels supported in the cell including a specialized channel like a high-speed shared channel. One or more measurements made at the base station are provided to the radio resource manager. Such measurements include other-channel power, high speed shared channel code usage, high speed shared channel transport format usage, average active load on the high speed shared channel, empty buffer, excess power, and similar parameters that relate to a high speed shared channel. One or more of these reported measurements may then be used to access, allocate, and/or regulate resources associated with the base station'"'"'s cell.
