The invention relates to devices and methods for signalling control information associated with transmission of data over a wireless channel. A second communication device receives (S2) data from a first communication device, wherein the data comprises an indication of recommended precoders and a recommendation of a first transmission rank to possibly use during transmission. The second communication device determines (S4) a second transmission rank to use for transmitting data, and transmits (S6) a confirmation message to the first communication device. The confirmation message comprises a confirmation that transmission of data from the second communication device is using at least parts of each recommended precoder associated with a frequency resource that falls within the transmission of data and an indicator of the second transmission rank to use.

Certain aspects of the present disclosure propose methods for supporting uplink transmit diversity in a wireless communication system. The proposed methods may eliminate ambiguity in decoding physical downlink control channel aggregation level and resources that are used by different antennas of a user equipment. In addition, a method is proposed for resource allocation for ACK/NACK repetition.
