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.

18. 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 at least two pairs of communication nodes for testing; allocating a common radio test resource for transmission from a transmitter in a first pair of communication nodes and from a transmitter in a 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. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)

27. A communication node in a multi-node wireless network, the communication node comprising a transmitter and further including a processor adapted to:
-
process information on a test probe message; and initiate transmission of the test probe message from the transmitter at a given point in time.

-
28. A communication node in a multi-node wireless network, the communication node comprising:
-
a receiver; a processor adapted to process information on a test probe message and initiate receipt of the test probe message at a given point in time; and a comparator adapted to verify the result from receipt of the test probe message. - View Dependent Claims (29, 30)

31. A method in a transmitting communication node, the method comprising:
-
receiving information on a test probe message; receiving instructions on the transmission of the test probe message on a common radio test resource at a given point in time; and transmitting the test probe message on the common radio test resource.
-
-
32. A method in a receiving communication node, the method comprising:
-
receiving information on the identity of an test probe message; receiving instructions on the receipt of the test probe message at a given point in time verifying receipt of the correct test probe message; and reporting receipt of the correct test probe message.
-
-
33. A control node in a multi-node wireless network, the control node comprising:
-
a system resource allocator; a probe instruction generator; a transmitter configured to transmit a probe message instruction; a receiver configured to receive a probe report including information on intelligible receipt of a test probe messages; and an evaluator configured to evaluate the probe report and to inform the system resource allocator of the result of the evaluation.

-
34. 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 at least two pairs of communication nodes for testing; allocating a common radio test resource for transmitting on a first radio path from a transmitter in a first pair of communication nodes and on a second radio path from a transmitter in a 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.
