    摘要： According to the present invention, a receiving node of a telecommunications network (20) (e.g. a radio base station (20) in uplink, or a mobile terminal (24) in downlink) transmits a single acknowledgement message to a transmitting node (e.g. a mobile terminal (24) in uplink, or a radio base station (22) in downlink) in respect of signals received over a plurality of frequency-aggregated carriers (component carriers) (10) between the transmitting and receiving nodes. If all signals are decoded correctly in the receiving node, a positive acknowledgement message (ACK) is sent to the transmitting node; if not all signals are decoded correctly, a negative acknowledgement message (NACK) is sent, or no acknowledgement message is sent. In this way, a single acknowledgement message can be sent for signals received over multiple carriers. The acknowledgement message can have the same format as legacy standards (for example, as specified in Release 8 of the 3GPP specifications), providing compatibility with existing equipment. The number of messages is also reduced compared with the straightforward approach of transmitting individual acknowledgement messages per component carrier.

    摘要： Methods and apparatus for generating, transmitting, and processing error control information in a wireless communication system are disclosed. The error control information is designed so that the probability of a NACK-to-ACK error in transmission is lower than the probability for an ACK-to-NACK error. Multiple ACK/NACK bits are transmitted along with one or more side information bits that indicate the relative quantities of ACK values and NACK values among the ACK/NACK bits. In an exemplary method for generating error control information in a communication device, a plurality of ACK/NACK bits indicating whether corresponding transport blocks were successfully received are generated. One or more side information bits are formed as a function of the ACK/NACK bits, the side information bits indicating the relative quantities of ACK values and NACK values among the ACK/NACK bits, and transmitted along with the ACK/NACK bits to the remote communication node.

    摘要： The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analyzing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.

    摘要： Methods and user equipment are provided for activation of downlink component carriers. Even though configured to monitor multiple component carriers, a user equipment unit does not start to monitor them immediately, but instead monitors only one or a few carriers initially. Once a downlink scheduling assignment is received, the user equipment unit will then monitor additional component carriers. After one or more subframes where the user equipment unit is not scheduled, the user equipment unit returns to its original state where it monitors one or a few carriers.
