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： Methods and arrangements for adjusting timing of transmissions in a radio communication system in which aggregation of component carriers is employed are disclosed. A base station sends a first TA command applicable to a first component carrier to a user equipment. A need to maintain different uplink transmission timing for the first user equipment component carrier and second uplink component carrier is detected by the base station. The base station then sends a second TA command based on the detected need to maintain different uplink transmission timing. The second TA command is applicable to uplink transmissions on the first component carrier and/or the second component carrier. The user equipment adjusts uplink transmissions on the first component carrier and/or the second uplink component carrier based on the second timing advance command.

摘要： A communication system includes a transmitting communication device (310) and a receiving communication device (320). The transmitting communication device (310) determines a control element, e.g., a control element of a Media Access Control protocol, associated with one of the carriers and provides the control element with an identifier specifying the carrier the control element is associated with. The transmitting communication device (310) sends the control element with the identifier on one of the carriers to the receiving communication device (320). The receiving communication device (320) receives the control element and determines, from the identifier received with the control element, the carrier the control element is associated with. Further, the receiving communication device (320) determines, on the basis of parameters indicated by the control element, a data transmission property of the carrier the control element is associated with.

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.
