Method and arrangement in a wireless communication system
First Claim
1. A method in a first node for adapting a signal to be sent over a radio link from the first node to a second node in a wireless communication system, wherein the second node is configured to use a codebook comprising a set of possible information alternatives for use by the first node in adapting the signal, said method comprising:
- sending a message to the second node comprising a configuration request to the second node to restrict selection of information alternatives by the second node to at least one subset of the set of possible information alternatives, wherein each subset comprises at least a part of the codebook and wherein the configuration request comprises a bit map that specifies which at least one subset to restrict the selection to; and
receiving a report of an information alternative from the second node, which information alternative is selected from the at least one subset configured according to the configuration request.

Abstract
A method for assisting the adaptation of a signal from a first node to a second node is provided. The first node communicates with the second node in a wireless communication system over a radio link. The second node has a codebook comprising a set of possible information alternatives for assisting the adaptation of a signal received from the first node. The second node may select an information alternative from the codebook and send it to the first node to assist the first node in adapting the signal. The first node is configured with a number of subsets, each comprising a part of the possible information alternatives. The first node requests that the second node restrict the selection of information alternatives to one of the subsets, and in response, receives an information alternative from the second node that is selected from among the subsets configured according to the configuration request.

21. A first node configured to communicate over a radio link with a second node in a wireless communication system, wherein the second node is configured to use a codebook comprising a set of possible information alternatives for use by the first node in adapting a signal to be sent from the first node to the second node over the radio link, said first node comprising:
-
a transmitter configured to send a message to the second node, the message comprising a configuration request to the second node to restrict selection of information alternatives by the second node to at least one subset of the set of possible information alternatives, wherein each subset comprises at least a part of the codebook and wherein the configuration request comprises a bit map that specifies which at least one subset to restrict the selection to; and a receiver configured to receive a report of an information alternative from the second node that was selected by the second node from the at least one subset, as configured according to the configuration request. - View Dependent Claims (22, 23, 24, 25)

26. A second node configured to communicate over a radio link with a first node in a wireless communication system, wherein the second node is configured to use a codebook comprising a set of possible information alternatives for use by the first node in adapting a signal to be sent from the first node to the second node over the radio link, said second node comprising:
-
a receiver configured to receive a message from the first node, the message comprising a configuration request to restrict selection of information alternatives by the second node to at least one subset of the set of possible information alternatives, wherein each subset comprises at least a part of the codebook and wherein the configuration request comprises a bit map that specifies which at least one subset to restrict the selection to; a processor circuit configured to select an information alternative from the at least one subset configured according to the configuration request; and a transmitter configured to report the selected information alternative to the first node. - View Dependent Claims (27, 28, 29, 30)
