Method and arrangement for allocating radio resources in a communication system

A method, performed at a network node, of facilitating radio resource allocation in a communication network comprising the network node, wherein the network node communicates with a user equipment via data streams over a radio interface on radio channels, the method comprising:

• receiving a channel quality message from a user equipment, the channel quality message having a length of a pre-defined number of bits and comprising:
• information that will be used by the network node in a comparison to determine an obtained channel quality based on whether the network node selects a single data stream transmission, or a multi data stream transmission, to communicate with the user equipment;
• and
• an indication of how many data streams the user equipment is requesting;
• and
• allocating available radio resources based on the channel quality message.

A user equipment that facilitates radio resource allocation in a communication network having a network node communicating with the user equipment via data streams over a radio interface on radio channels, the user equipment comprising:

• a reporting function configured to prepare a channel quality message to have a length of a pre-defined number of bits, and to comprise:
• information that a network node in a communication network will use in a comparison to determine an obtained channel quality based on whether the network node selects a single data stream transmission, or a multi data stream transmission, for communicating with the user equipment;
• and
• an indication of how many data streams the user equipment is requesting;
• and
• a transmitter configured to transmit the channel quality message to the network node so that the network node can allocate available radio resources based on the channel quality message.

A network node for facilitating radio resource allocation in a communication network including the network node, wherein the network node communicates with a user equipment via data streams over a radio interface on radio channels, the network node comprising:

• a receiver configured to receive a channel quality message from a user equipment, the channel quality message having a length of a pre-defined number of bits and comprising:
• information that will be used by the network node in a comparison to determine an obtained channel quality based on whether the network node selects a single data stream transmission, or a multi data stream transmission, to communicate with the user equipment;
• and
• an indication of how many data streams the user equipment is requesting;
• and
• a resource allocation function configured to allocate available radio resources based on the channel quality message.
