Radio resource control signaling for physical layer configuration changes

A method for use in configuring a connection with a mobile radio over a radio channel, comprising:

• establishing the connection with the mobile radio using a configuration of the radio channel which specifies a first transport format;
• sending a message that will involve reconfiguring the radio channel configuration;
• determining that one or more rate matching parameters must be configured as a result of the reconfiguration;
• and
• configuring the one or more rate matching parameters without having to configure the first transport format.

A mobile user equipment terminal for use in a mobile radio communications system, comprising:

• radio processing circuitry for sending and receiving signals over a radio interface, and
• control circuitry, coupled to the radio processing circuitry, configured to:
• establish a connection over a radio channel using the radio processing circuitry, where the radio channel has a first configuration which specifies a first transport format;
• detect a need for a reconfiguration of the radio channel configuration;
• determine that one or more rate matching parameters must be configured as a result of the reconfiguration;
• and
• configure the one or more rate matching parameters without having to configure the first transport format.

A radio network for use in a mobile radio communications system, comprising:

• radio processing circuitry for sending and receiving signals over a radio interface, and
• control circuitry configured to:
• establish a connection over a radio channel using the radio processing circuitry, where the radio channel has a first configuration which specifies a first transport format;
• detect a need for a reconfiguration of the radio channel configuration;
• determine that one or more rate matching parameters must be configured as a result of the reconfiguration;
• and
• configure the one or more rate matching parameters without having to configure the first transport format.
