摘要： Methods and user equipment are provided for activation of downlink component carriers. Even though configured to monitor multiple component carriers, a user equipment unit does not start to monitor them immediately, but instead monitors only one or a few carriers initially. Once a downlink scheduling assignment is received, the user equipment unit will then monitor additional component carriers. After one or more subframes where the user equipment unit is not scheduled, the user equipment unit returns to its original state where it monitors one or a few carriers.

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.

摘要： The present invention relates to methods and arrangements in a base station and a user equipment for determining an uplink transmission timing correction for communication in a telecommunication system in which aggregation of component carriers is applied. The base station receives a signal from the user equipment on a uplink (UL) component carrier and measures the arrival time of the signal. A timing correction of the UL transmission timing based on the arrival time of the signal is determined. Thereupon the base station determines for which of the uplink component carriers used by the user equipment the timing correction is valid. The timing correction and the validity information is sent to the user equipment. The user equipment adjusts the UL transmission timing for each UL component carrier the timing correction is valid for.

摘要： The basic idea of the present invention is to not only design a frequency-selective precoder with respect to the channel properties but also to ensure that the time-domain spread is limited. Hence the energy of the time-domain impulse response of the frequency-selective precoder is concentrated. According to a first embodiment, the time-domain spread is limited by designing a precoder such that it allows smooth transitions in the frequency domain between the values of the precoder when the precoder provides a staircase function. The smooth transitions can either be achieved by lowpass filtering the frequency-domain representation, the staircase function, of the precoder or by designing the precoder such that the sharp jumps are replaced by slopes. According to a second embodiment, the time-domain spread is controlled. The control may be achieved by employing a time-domain parameterization to precisely control the introduced additional time-domain spread.
