Method and apparatus for cell-specific HSDPA parameter configuration and reconfiguration

A method by which, for a cell in which user equipment devices access a radio network via a Node B under the supervision of a controlling radio network controller (CRNC), resources are reserved for providing high speed downlink packet access (HSDPA) via a high speed downlink shared channel (HS-DSCH) and one or more corresponding physical channels (HS-PDSCHs) into which the HS-DSCH is mapped, characterized by:

• a step (61) in which the CRNC for the Node B serving the cell sends to the Node B a message conveying cell-specific HSDPA information indicating resources requested by the CRNC including codes for the HS-DSCH and for an associated high speed shared control channel (HS-SCCH) and also indicating a maximum allowed value for the combined power of the HS-SCCH and each the corresponding physical channels (HS-PDSCHs) into which the HS-DSCH is mapped;
• and
• a step (63) in which the Node B communicates to the CRNC a cell-specific HSDPA resource response indicating information about resources successfully reserved by the Node B in response to the message conveying cell-specific HSDPA information.
