摘要： A technique for generating a reference signal for use in a communication system in which for reference signal generation multiple base sequences are defined is presented. A method implementation of the technique comprises generating a first reference signal sequence from a first base sequence and a second reference signal sequence from a second base sequence. A reference signal is generated that comprises the first reference signal sequence and the second reference signal sequence. The first reference signal sequence occupies a first spectral fragment of the reference signal, and the second reference signal sequence occupies a second spectral fragment of the reference signal. The second spectral fragment and the first spectral fragment do not overlap.

摘要： A dynamic frequency translating repeater operating in a mobile communications system is operable to receive a multi-user signal and perform time-varying and user-specific frequency shifting in the repeater signal. The dynamic frequency translating repeater may further perform user subcarrier specific dynamic frequency translation. Different mobile stations may be allocated different frequency shift amounts based on the interference environments, resource allocations, and scheduling constraints particular to each mobile station.

摘要： In a wireless network supporting aggregation of uplink component carriers, sounding reference signals, SRS, are transmitted (62) on an uplink, UL, primary component carrier. An activation command corresponding to an UL secondary component carrier, SCC, is received (64), in response to which the receiving transceiver determines (65) whether it has valid timing information for the UL SCC, wherein valid timing information for the UL SCC indicates that the UL SCC is UL synchronized. In response to this determination, transmission of SRS on the UL SCC is enabled (66) if the UL SCC is synchronized, when SRS is configured for the UL SCC. Otherwise, transmission of SRS on the UL SCC is prohibited (68) until the UL SCC is UL synchronized.

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： In a communication system using aggregation of component carriers, a transmitter comprises a transmitting entity configured to transmit data messages on multiple component carriers. The transmission of the data messages is accomplished on the basis of a retransmission protocol. The retransmission protocol requires sending of an acknowledgement message in response to verifying correct receipt of a data message. A receiver comprises a receiving entity configured to receive the data messages on the basis of the retransmission protocol. In response to a decision to deactivate transmission on one of the aggregated component carriers, the retransmission protocol is triggered to retransmit those data messages for which no acknowledgement message of the retransmission protocol has been received. The retransmission is accomplished on at least one other of the component carriers. A further retransmission protocol may be used on each of the component carriers, with respective transmitting entities in the transmitter and respective receiving entities in the receiver.

摘要： A method of providing signal synchronization for a radio access network may include transmitting a first carrier including synchronization signals on a first frequency from the radio access network. Information relating the first carrier on the first frequency with a second carrier on a second frequency may be transmitted from the radio access network, with this information being intended to be used in synchronization by a wireless terminal upon addition of the second carrier. More particularly, the first and second frequencies may be different. A command to add the second carrier as a downlink for transmissions may be transmitted to the wireless terminal. Related network nodes and wireless terminals are also discussed.
