Systems and methods relating to control channel transmission in a cellular communications network that are particularly well-suited for use with, but not limited to, Carrier Aggregation (CA) with a large number of Component Carriers (CCs) are disclosed. In some embodiments, a method of operation of a wireless device in a cellular communications network comprises receiving an indicator from a base station that indicates that a transmit scheme utilized by the wireless device for transmission of an uplink control channel is to be changed. The method further comprises, upon receiving the indicator, changing the transmit scheme utilized by the wireless device for transmission of the uplink control channel in accordance with the indicator. In this manner, the transmit scheme utilized by the wireless device for transmission of an uplink control channel can be adapted to, e.g., operating conditions. |
