Method and arrangement in a wireless communications 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, said method comprising:
- sending a configuration request to the second node to restrict a selection of information alternatives by the second node to at least one subset of a set of possible information alternatives, each subset comprising at least a part of a codebook; and
receiving an information alternative from the second node, wherein the information alternative has a specific signaling format suitable for communicating another information alternative selected from at least one other subset different than the at least one subset.

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.

13. A method in a second node for assisting a first node in the adaptation of a signal to be sent over a radio link from the first node to the second node in a wireless communication system, said method comprising:
-
receiving, from the first node, a configuration request to restrict a selection of information alternatives by the second node to at least one subset of a set of possible information alternatives, wherein each subset comprises at least a part of a codebook; and sending a selected information alternative to the first node using a specific signaling format suitable for sending another information alternative selected from at least one other subset different than the at least one subset. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A first node in a wireless communication system that is configured to communicate over a radio link with a second node in the wireless communication system, said first node comprising:
-
a transmitter configured to send a configuration request to the second node to restrict a selection of information alternatives by the second node to at least one subset of a set of possible information alternatives, each subset comprising at least a part of a codebook; and a receiver configured to receive an information alternative from the second node wherein the information alternative has a specific signaling format suitable for communicating another information alternative selected from at least one other subset different than the at least one subset. - View Dependent Claims (22, 23, 24)

25. A second node in a wireless communication system, the second node configured to communicate with a first node in the wireless communication system over a radio link, said second node comprising:
-
a receiver configured to receive, from the first node, a configuration request to restrict a selection of information alternatives to at least one subset of a set of possible information alternatives, each subset comprising at least a part of a codebook; and a transmitter configured to send a selected information alternative to the first node using a particular signalling format, wherein the signalling format is reusable for signalling at least one other information alternative from at least one other subset. - View Dependent Claims (26, 27, 28)
