摘要： User Equipment, UE (30), in a wireless radiocommunication network (10) supporting Coordinated Multi-Point, CoMP, transmissions may autonomously adopt an assumption of the quasi co-located (QCL)status of two (or more) antenna ports that is different from the default QCL status defined or signaled by the network (10), in response to one or more estimates of certain operating parameter values. The altered QCL status assumption allows the UE (30) to correct parameter estimates more accurately, and/or to reduce complexity in the parameter estimation correction.

摘要： An example method of mapping a set of reference signal samples to subcarriers is disclosed. First and second subsets of samples having contiguous index values are determined. The second subset of samples are mapped to a first subset of subcarriers, such that a first sample of the second subset of samples having a lowest index value of the second subset of samples is mapped to a first subcarrier at a first end of a bandwidth. The first subset of samples are mapped to a second subset of subcarriers of the bandwidth, such that a last sample of the first subset of samples having a highest index value of the first subset of samples is mapped to a last subcarrier at an opposite second end of the bandwidth. A complementary method of demapping subcarriers is also disclosed.

摘要： A radio resource allocation method in a communication node is disclosed. The method comprises determining (424) that a first time reference or a first communication using a first component carrier has a time shift compared to a second time reference of a second communication using a second component carrier. The method further comprises determining (426) a duration of a communication sub-frame based on the time shift, and scheduling (428) the determined communication sub-frame on a first component carrier to a first communication device. The determined frame duration is equal to the time shift or equal to the normal sub-frame length minus the time shift so as to avoid any overlap or interference. Corresponding computer program product, arrangement, communication node and first communication device are also disclosed.

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： The present invention relates to a transmitter and to a receiver and methods thereof wherein the PAPR is reduced by applying a set of different phase rotations to the output of each DFT of the transmitter. A corresponding set of inverse phase rotations are applied to the input of the IDFT of the receiver. The set of phase rotations applied to the subcarriers at the output of the DFT precoder of the transmitter results in a circular time shift of the corresponding time domain at the output of the IDFT modulator. If the phase rotations are properly selected for each DFT precoder, the probability that signal peaks sum in a constructive way at the output of the IDFT modulators is reduced, with a consequent reduction of the PAPR.
