1. A radio network element, comprising:
- an admission control unit, responsive to radio access bearer parameters provided by a core network entity, to provide commands to a media access control sublayer specifying how the media access control sublayer is to allocate resources so as to communicate a higher rate data flow received from the core network entity to a mobile user equipment, the higher rate data flow being provided to the radio network element at a higher rate than the user equipment can accept on a single channel; and
the media access control sublayer to provide a plurality of media access control data flows at a rate low enough to be suitable for reception by the user equipment, and to include with each lower rate data flow information indicating how the lower rate flows are to be combined by the user equipment,wherein the lower rate data flows are suitable for transmission according to a protocol not taking into account that the lower rate data flows are in combination with a radio link control data flow corresponding to the higher rate data flow.

Abstract
A channel inverse multiplexer/multiplexer (IMUX/MUX) (14a) of a MAC sublayer (14) of a UTRAN RNC (11) for providing to a UE (18) traffic (communication signals including in general both control and user data) at a higher rate than the UE can accept over a single channel. The channel IMUX/MUX performs inverse multiplexing of traffic for downlink, and multiplexing of traffic on uplink, and does so in a way that is transparent to all other layers/entities of the UTRAN (11 17) and to the UE (18).

7. A method, comprising:
-
responsive to radio access bearer parameters provided by a core network entity, providing a command specifying how resources are to be allocated so as to communicate a higher rate data flow received from the core network entity to a mobile user equipment, the higher rate data flow being provided at a higher rate than the user equipment can accept on a single channel; responsive to the command, providing a plurality of media access control data flows at a rate low enough to be suitable for reception by the user equipment; and including with each lower rate data flow information indicating how lower rate flows are to be combined by the user equipment to reconstruct an original data traffic from the core network entity, wherein the lower rate data flows are suitable for transmission according to a protocol not taking into account that the lower rate data flows are in combination with a radio link control data flow corresponding to the higher rate data flow. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system, comprising:
-
a radio network controller including a media access control sublayer to provide a plurality of media access control data flows for communication to a user equipment, each of the media access control data flows being at a lower rate than a first rate, in response to a radio link control data flow from a core network entity at the first rate, and to include with each lower rate data flow information indicating how media access control data flows are to be combined by the user equipment; and a base station communicatively coupled to the radio network controller, for wirelessly communicating the media access control data flows to the user equipment according to a wireless communication protocol, wherein the lower rate data flows are suitable for transmission according to a protocol not taking into account that the lower rate data flows are in combination with a radio link control data flow corresponding to the higher rate data flow. - View Dependent Claims (14, 15, 16, 17, 18, 19)
