Abstract:
1. A method in a mobile terminal for processing downlink control information, wherein the mobile terminal is capable of receiving multiple component carriers, the method comprising: receiving downlink control information on a component carrier, the downlink control information comprising a bit field allocated for a transmit power control command for the mobile terminal; determining, based on a rule relating to a component carrier bandwidth, whether the component carrier with the narrowest bandwidth carries the transmit power control command; when the component carrier with the narrowest bandwidth does not carry the transmit power control command, determining that none of the bits in the bit field are used for the transmit power control command; when the component carrier with the narrowest bandwidth carries the transmit power control command, determining whether one or more bits in the bit field are not used for the transmit power control command; when the bit field comprises one or more bits that are not used for the transmit power control command, interpreting the meaning of the bits not used for the transmit power control command in different ways, depending on an ACK/NACK feedback mode with which the mobile terminal is configured, wherein interpreting includes:
