摘要： A receiver uses a local oscillator to receive data transmitted via a combination of radio frequency signals using carrier aggregation. Each radio frequency signal occupies a respective radio frequency band and the radio frequency bands are arranged in two groups, a first group and a second group, separated in frequency by a first frequency region, each of the groups including one or more radio frequency bands and the first group occupying a wider frequency region than the second group. The radio frequency signals are processed using the local oscillator by setting the local oscillator, during the processing, to a frequency that is offset from the centre of a band defined by outer edges of the frequency regions occupied by the two groups.

摘要： There are provided measures for enabling power control for inter-band multi-carrier capable devices, such as e.g. inter-band carrier aggregation capable devices. Such measures may exemplarily include calculating at least one output power restriction value for a cumulative output power for a combination of at least two uplink carriers of a terminal device, said two uplink carriers operating on different bands, signaling the calculated at least one output power restriction value to the terminal device, and performing power control for the at least two uplink carriers using the acquired at least one output power restriction value at the terminal device.

摘要： There is provided a mechanism for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between a first set UL communications performed on at least two different frequency bands and a DL communication performed on another frequency band is determined, a frequency carrier deactivation processing is conducted so as to deactivate either one of carriers of the at least two frequency bands of the set of UL communications. The deactivation processing comprises for example an autonomous denial on the UE side or an interference reporting with deactivation on the eNB side.

摘要： Data is received that has been transmitted via a combination of radio frequency signals using carrier aggregation, each radio frequency signal occupying a respective radio frequency band, the bands being arranged in two groups separated in frequency by a first frequency region, the first of the two groups occupying a wider frequency region than the second group. Inphase and quadrature components of the radio frequency signals are filtered using a first bandpass filter bandwidth to give first bandpass filtered components and filtered using a second bandpass filter bandwidth, different from the first bandpass filter bandwidth, to give second bandpass filtered components. A reconfigurable receiver is configurable to a first mode to receive the combination of radio frequency signals, and is also configurable to at least a second mode. At least one first filter is configured, in the first mode, to use a first bandpass filter bandwidth and, in the second mode, to use a lowpass filter bandwidth. At least one second filter is configured, in the first mode, to use a second bandpass filter bandwidth, different from the first bandpass filter bandwidth.
