Abstract
Method and arrangement in a base station for adjusting a channel quality indicator value of a wireless transmission between the base station and a user equipment. The base station, the user equipment and a relay node are comprised in a multi-hop wireless communication system and adapted to intercommunicate in a first transmission mode and a second transmission mode. The method comprises sending a radio signal to be received by the user equipment, obtaining a measurement of the channel quality indicator value, determining if the transmission mode of the sent radio signal is different from the transmission mode of the obtained channel quality indicator value measurement, and adding a channel quality indicator offset value to the channel quality indicator value, if the transmission mode of the relay node is determined to be the first transmission mode while the channel quality indicator was measured and obtained in the second transmission mode.

16. A method in a base station for adjusting a channel quality indicator value related to the channel quality of a wireless transmission between the base station and a user equipment served by the base station, where the base station, the user equipment and a relay node are included in a multi-hop wireless communication system and configured to intercommunicate in a first transmission mode and a second transmission mode, the method comprising:
-
sending a radio signal to be received by the user equipment; obtaining a measurement of the channel quality indicator value; determining if the transmission mode of the sent radio signal is different from the transmission mode of the obtained channel quality indicator value measurement; and adding a channel quality indicator offset value to the channel quality indicator value, if the transmission mode of the relay node is determined to be the first transmission mode while the channel quality indicator was measured and obtained in the second transmission mode. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. An arrangement in a base station for adjusting a channel quality indicator value related to the channel quality of a wireless transmission between the base station and a user equipment served by the base station, the base station, the user equipment and a relay node included in a multi-hop wireless communication system and configured to intercommunicate in a first transmission mode and a second transmission mode, the arrangement comprising:
-
a sending unit configured to send a radio signal to be received by the user equipment; an obtaining unit configured to obtain a measurement of the channel quality indicator value; a determination unit configured to determine if the transmission mode of the sent radio signal is different from the transmission mode of the obtained channel quality indicator value measurement; and an adjusting unit configured to add a channel quality indicator offset value to the channel quality indicator value, if the transmission mode of the relay node is determined to be the first transmission mode while the channel quality indicator was measured and obtained in the second transmission mode. - View Dependent Claims (28)
