Methods and arrangements for allocation of radio resources
First Claim
1. A method for allocating a common radio resource for simultaneous transmission of data streams in multiple pairs of communication nodes in a multi-node wireless network, the method comprising:
- selecting, for testing, a first pair of communication nodes and a second pair of communication nodes, the first and second pairs of communication nodes have no communication node in common;
allocating a common radio test resource for transmission from a transmitter in the first pair of communication nodes and from a transmitter in the second pair of communication nodes;
transmitting a first test probe message from the transmitter in the first pair of communication nodes on the common radio test resource and, during at least a partly overlapping time interval, transmitting a second test probe message from the transmitter in the second pair of communication nodes on the common radio test resource;
verifying receipt of the first test probe message in the receiver in the first pair of communication nodes and receipt of the second test probe message in the receiver in the second pair of communication nodes; and
allocating the common radio test resource as the common radio resource to the transmitter in the first pair of communication nodes and to the transmitter in the second pair of communication nodes if the first test probe message is received in the receiver in the first pair of communication nodes and the second test probe message is received in the receiver in the second pair of communication nodes.

Abstract
The invention relates to a method for allocating a common radio resource for simultaneous transmission of data streams in multiple pairs of communication nodes in a multi-node wireless network. The invention also relates to a method of assessing radio resource isolation in a multi-node wireless network. The inventive methods include transmission (44) of at least a first and a second test probe message on a common radio test resource. Receipt of the intended test probe messages are verified (45), whereupon radio resource isolation may be determined and a common radio resource allocated (46) for transmission in the tested communication node pairs. The invention also relates to a communication node and a control node wherein the inventive methods are applied.

10. A method in a control node to assess radio resource isolation in a multi-node wireless system including multiple pairs of communication nodes, the method comprising:
-
selecting, for testing, a first pair of communication nodes and a second pair of communication nodes, the first and second pairs of communication nodes have no communication node in common; allocating a common radio test resource for transmitting on a first radio path from a transmitter in the first pair of communication nodes and on a second radio path from a transmitter in the second pair of communication nodes; initiating transmission of a first test probe message from the transmitter in the first pair of communication nodes on the common radio test resource and transmission of a second test probe message, during an at least partly overlapping time interval, from the transmitter in the second pair of communication nodes on the common radio test resource; initiating receipt of the first test probe message in the receiver in the first pair of communication nodes and receipt of the second test probe message in the receiver in the second pair of communication nodes; receiving reports on the receipt of the test probe messages; and allocating the common radio test resource as a common radio resource if the intended test probe messages are received in their respective receivers.
