    摘要: Downlink control information, DCI, messages used for signaling downlink resource grants are employed for triggering sounding reference signal transmission in the uplink. An index of the uplink component carrier that should be used for the transmission is derived from SIB-2 linking between the downlink component carrier targeted by the downlink DCI message and one of the uplink component carriers configured for the mobile station, when the linking is available. In some cases the downlink component carrier targeted by the downlink DCI message is identified by a carrier identification field in the downlink DCI. Variants of the disclosed techniques involve a default uplink component carrier, which is used in the event that the SIB-2 based allocation is not possible or desired. The default uplink component carrier can be statically defined or semi-statically signaled by Radio Resource Control, RRC, signaling.

    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.

    摘要: Methods and apparatus for generating, transmitting, and processing error control information in a wireless communication system are disclosed. The error control information is designed so that the probability of a NACK-to-ACK error in transmission is lower than the probability for an ACK-to-NACK error. Multiple ACK/NACK bits are transmitted along with one or more side information bits that indicate the relative quantities of ACK values and NACK values among the ACK/NACK bits. In an exemplary method for generating error control information in a communication device, a plurality of ACK/NACK bits indicating whether corresponding transport blocks were successfully received are generated. One or more side information bits are formed as a function of the ACK/NACK bits, the side information bits indicating the relative quantities of ACK values and NACK values among the ACK/NACK bits, and transmitted along with the ACK/NACK bits to the remote communication node.
