A method (1000, 1200) performed at a consumer node of a wireless network, said consumer node having one primary serving cell and at least four secondary serving cells, the method comprising: monitoring channel transmissions of a sub frame from each of a plurality of activated serving cells serving the consumer node, the activated serving cells being grouped into first and second cell groups in which the first cell group includes said primary serving cell and one or more of said at least four secondary serving cells and the second cell group includes one or more of said at least four secondary serving cells different from the secondary serving cells of the first cell group; determining, for each activated serving cell based on the monitoring, whether information for the consumer node is detected in the subframe of the channel transmission from that activated serving cell; determining (830, 850), for each of the first and second cell groups, whether that cell group is a discontinuous transmission cell group or a non-DTX cell group, a DTX cell group being a cell group in which no information is detected in the subframe of the channel transmission from any activated serving cell in that cell group and a non-DTX cell group being a cell group in which information is detected in the subframe of the channel transmission from at least one activated serving cell in that cell group; transmitting (1070, 1270), when one of the first and second cell groups is the DTX cell group and the other is the non-DTX cell group, one of first and second feedback information on corresponding one of first and second feedback channels associated with the non-DTX cell group to the primary serving cell, and withholding (1080, 1280) transmission of the other of the first and second feedback information on the other of the first and second feedback channels associated with the DTX cell group, wherein the first and second feedback channels are Q and I-branches, respectively, of an I/Q multiplexed High-Speed Dedicated Physical Control Channel (HS-DPCCH), and wherein the feedback information transmitted on the one feedback channel is transmitted with a boosted transmit power level, the boosted transmit power being greater than the transmit power that would be used on the one feedback channel to transmit feedback information in a situation where the first feedback information and the second feedback information are transmitted on the first feedback channel and the second feedback channel, respectively. monitoring channel transmissions of a sub frame from each of a plurality of activated serving cells serving the consumer node, the activated serving cells being grouped into first and second cell groups in which the first cell group includes said primary serving cell and one or more of said at least four secondary serving cells and the second cell group includes one or more of said at least four secondary serving cells different from the secondary serving cells of the first cell group; determining, for each activated serving cell based on the monitoring, whether information for the consumer node is detected in the subframe of the channel transmission from that activated serving cell; determining (830, 850), for each of the first and second cell groups, whether that cell group is a discontinuous transmission cell group or a non-DTX cell group, a DTX cell group being a cell group in which no information is detected in the subframe of the channel transmission from any activated serving cell in that cell group and a non-DTX cell group being a cell group in which information is detected in the subframe of the channel transmission from at least one activated serving cell in that cell group; transmitting (1070, 1270), when one of the first and second cell groups is the DTX cell group and the other is the non-DTX cell group, one of first and second feedback information on corresponding one of first and second feedback channels associated with the non-DTX cell group to the primary serving cell, and withholding (1080, 1280) transmission of the other of the first and second feedback information on the other of the first and second feedback channels associated with the DTX cell group, wherein the first and second feedback channels are Q and I-branches, respectively, of an I/Q multiplexed High-Speed Dedicated Physical Control Channel (HS-DPCCH), and wherein the feedback information transmitted on the one feedback channel is transmitted with a boosted transmit power level, the boosted transmit power being greater than the transmit power that would be used on the one feedback channel to transmit feedback information in a situation where the first feedback information and the second feedback information are transmitted on the first feedback channel and the second feedback channel, respectively.
