| 20110200016 | HARQ ACK/NACK Signalling for Multi-Carrier HSDPA - 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 group by 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. | 08-18-2011 |
| 20110243264 | Methods and Devices for Carrier Activation/Deactivation in a Multi-Carrier Communication System - The present invention relates to 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 from a radio base station to a user equipment. The HS-SCCH order is encoded by the radio base station 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 interprets the encoded HS-SCCH order 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 to calculate the encoded HS-SCCH order based on the desired activation status. | 10-06-2011 |

| 20130064180 | HARQ-ACK FEEDBACK DETECTION FOR AN I/Q-MULTIPLEXED CONTROL CHANNEL - In a network that provides high-speed packet access, a mobile terminal is served by multiple activated serving cells which are grouped into cell groups. The mobile terminal monitors control channel transmissions to detect whether there are any transmissions for the mobile terminal from the activated serving cells for each cell group and provides feedback to a primary serving cell. When no transmission is detected from serving cells of a particular cell group, the mobile terminal may transmit feedback information explicitly indicating that no transmission is detected for that cell group. Alternatively, the mobile terminal may withhold transmitting feedback for that cell group and increases the power for transmitting the feedback information for cell groups in which transmissions were detected. | 03-14-2013 |
