Abstract: Uplink control information transmission method, and a network node and a UE implementing the method are disclosed. According to an embodiment of the invention, uplink control information is transmitted from a UE to a network node by defining a set including at least one of the of uplink component carriers being usable for carrier aggregation for the UE. For this set, a priority indication is assigned to each one of the at least one uplink component carrier included in the set. Then, if this set includes at least one uplink component carrier comprising an uplink shared channel, one of these at least one uplink component carrier comprising an uplink shared channel is selected for transmission of uplink control information in that uplink shared channel. Selection based on at least one of the at least one assigned priority indication, when selecting uplink component carrier, is disclosed.

Abstract: A mobile station is connected to a multi-carrier cellular communication system having a plurality of sub-carriers. The sub-carriers are classified into K frequency sub-bands, channel state information (CSI) of the frequency sub-bands is represented by matrices Wi (i=0 . . . K−1), where K is an integer grater than 1. The mobile station determines a first sub-index k1 for the K matrices Wi (i=0 . . . K−1), and a second sub-index k2 for each one of the K matrices Wi (i=0 . . . K−1). The first sub-index k1 is common for all frequency sub-bands, and the second sub-index k2 is specific for the indexed matrix that corresponds to one frequency sub-band. The mobile station reports to a base station of the multi-carrier cellular communication system the first sub-index k1 and at least one second sub-index k2.
