摘要： A communication method includes transmitting resource assignment information including bits that indicate activation or deactivation statuses of respective downlink component carriers, which are secondary downlink component carriers added to a primary component carrier which is always activated, each of the downlink component carriers corresponding to one bit included in bits, and the one bit indicating that a corresponding downlink component carrier is to be activated or deactivated. When any one bit of the bits indicates that its corresponding downlink component carrier is to be activated, the bits jointly indicate the activation or deactivation statuses, a sounding reference signal (SRS) transmission request and a channel quality information (CQI) reporting request. The method also includes receiving a SRS and a CQI that are transmitted, in response to the SRS transmission request and the CQI reporting request, on an uplink component carrier linked to an activated downlink component carrier(s).

摘要： This invention concerns concepts for signaling resource allocation information to a terminal that indicates to the terminal assigned resources for the terminal. The terminal can receives downlink control information (DCI), which comprises a field for indicating the resource allocation information of the terminal. This resource assignment field within the DCI has a predetermined number of bits. The terminal can determines its assigned resource allocation information from the content of the received DCI, even though the bit size of the resource allocation field in the received DCI is insufficient to represent all allowed resource allocations. According to an embodiment, the received bits that are signaled to the terminal in the DCI represent predetermined bits of the resource allocation information. All remaining one or more bits of the resource allocation information that are not included in the field of the received DCI are set to predetermined value.

摘要： The present invention relates to a method for receiving control information within a subframe of a multi-carrier communication system supporting carrier aggregation, the method comprising the following steps performed at a receiving node: performing a blind detection for the control information within a search space by means of a first search pattern, wherein the first search pattern is one of a plurality of search patterns, each of the plurality of search patterns comprising a plurality of candidates distributed on any of a plurality of aggregation levels, and wherein the plurality of search patterns further comprises a second search pattern whose candidates are non-overlapping the candidates of the first search pattern on the same aggregation levels.

摘要： The invention relates methods for triggering channel quality feedback for at least one of plural component carriers of a communication system available for downlink transmission. The invention suggests a mechanism for triggering channel quality feedback from a terminal where the downlink control signaling overhead for the selection of component carrier(s) to be reported on is minimized. One aspect of the invention is a new interpretation of a predetermined format for dedicated control information comprising a CQI request flag, which is depending on the status of the CQI request flag. In case the CQI request flag is set at least one further bit of the dedicated control information is interpreted as information indicative of the one or more component carriers available for downlink transmission to the terminal and the terminal is providing channel quality feedback on the channel quality experienced on the indicated component carrier or component carriers.

摘要： The present invention relates to reporting the channel state information in a communication system. The channel state information is reported from the user terminal to a base station. Accordingly, the user terminal determines a first channel state information value from a first set of values (levels) and a second channel state information value from another set of values, preferably a larger set of values. Then a difference or other relative measure is calculated between the first and the second channel state information value and transmitted to the base station.

摘要： The present disclosure relates to transmitting transport blocks in subframes of a predefined length within a wireless communication system. A downlink control information including a resource grant comprising a predetermined modulation and a predetermined transport block size is received (user equipment is the transmitter) or generated (base station is the transmitter). Then transport block including channel coded data to be transmitted in a subframe with the predetermined modulation and the predetermined transport block size is generated. Sensing is performed in the subframes and based thereon, it is determined whether a partial subframe or a complete subframe is available for transmission of the generated transport block. Finally, the transport block is transmitted with a modified modulation different from the predetermined modulation if the partial rather than complete subframe is available. Correspondingly, at the receiver, the grant is received (user equipment is receiver) or generated (base station is the receiver), the size of the subframe in which the reception is expected is determined and then the transport block is received with a modified modulation if only the partial subframe is available.

摘要： The present invention relates to a method for configuring a retransmission protocol on the uplink between a network node and a relay node in a mobile communication system, the configuration being performed at a network node or at a relay node, and to the corresponding relay node apparatus and network node apparatus capable of configuring the retransmission protocol. In particular, the number of transmission processes is determined based on the position of time intervals available for the transmission and may be selected in order to control the round trip time of the retransmission protocol. Once the number of transmission processes has been configured, the transmission processes are mapped on the available time intervals in a predefined order and repetitively.

摘要： This invention relates to the proposal of component carrier (de)activation message that is allowing a activation or deactivation of one or more component carriers in the uplink or downlink. Furthermore, the invention relates to the use of the new component carrier (de)activation message in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, the invention proposes to use component carrier-specific or cell-RNTI(s) for the scrambling of the CRC of the component carrier (de)activation message, and to explicitly indicate the intended recipient of the component carrier (de)activation message in a corresponding field in the message. Furthermore, the invention further proposes different designs of the component carrier (de)activation message and further uses thereof, so as to trigger CQI reporting and/or SRS transmission by a mobile terminal.
