摘要： The invention relates to methods and apparatuses that facilitate control of radio link quality of uplink MIMO transmissions. A quality difference between different encoded signals is reduced by interleaving the encoded signals over different virtual antennas (17, 18) in a user equipment. The interleaving can be performed on different time-scales and at different stages of the transmission procedure. According to some embodiments encoded transport blocks (103, 4) are interleaved over the virtual antennas (17, 18) to achieve a more even radio link quality between the transport blocks (103, 104). In some embodiments a physical layer transmission of data and a physical layer retransmission of the same data are carried out from different virtual antennas (17, 18) to reduce the quality difference between data transmitted from different virtual antennas.

摘要： The present invention relates to a methods and devices for use in multi carrier communication systems in which secondary downlink and secondary uplink carriers may be dynamically activated/deactivated by means of transmitting an HS-SCCH order (23) from a radio base station (21) to a user equipment (22). The HS-SCCH order (23) is encoded by the radio base station (21) according to an order mapping. The order mapping maps a desired activation status of a set of carriers to a corresponding encoded HS-SCCH order. The user equipment (22) interprets the encoded HS-SCCH order (23) to derive the desired activation status of the set of carriers. By using an appropriate order mapping, operations in the radio base station and/or the user equipment may be simplified, e.g. by allowing the radio base station (21) to calculate the encoded HS-SCCH order (23) based on the desired activation status.

摘要： Techniques are disclosed for signaling retransmission-related information in a multi-carrier wireless communication system supporting three or more carriers. In an example method, a wireless transceiver forms a first ACK/NACK groupby jointly coding ACK bits and NACK bits for a first subset of the carriers, and transmits the first ACK/NACK group during a first transmission slot allocated for the first ACK/NACK group. If no carriers of a second subset of the carriers are activated for the wireless transceiver, then the first ACK/NACK group is also transmitted during a second transmission slot that is otherwise allocated to ACK/NACK information for a second subset of the carriers. In another method, first and second ACK/NACK groups corresponding to first and second subsets of carriers are each formed from a codebook comprising a DTX codeword indicating that no data transmission for the mobile station was detected for the corresponding subset of carriers.
