Abstract: An arrangement for a transmitter and/or receiver which is adapted to allow carrier aggregation in a wireless communication system, comprising a plurality of radio frequency (RF) blocks, each of which is inherently adapted to operate substantially across (in the region of) one of the particular groups of frequency ranges. The number of groups may be 5 or less.

Abstract: A dynamic data transmission adjustment method in a wireless communication system. The system includes a base station and a user equipment. The base station and the user equipment communicate amongst themselves by using a first transmission technique. The method includes transmitting a plurality of frames between the base station and the user equipment using a regular transmission scheme according to the first transmission technique, and at least one iteration of the following steps: calculating a specific error rate in at least one specific region of the transmitted frames; and adjusting the regular transmission scheme when a value representative of the specific error rate associated to the specific region exceeds a predetermined threshold.

Abstract: A method and apparatus are provided for cancelling interferences of a received MIMO RF signal. The method includes: receiving a signal y; an initial step of obtaining, from the received signal y, at least one data representative of the received signal, called decoded data; computing the decoded data as a function of at least one predetermined criterion, delivering feedback data and a feedback decision; and, as a function of the feedback decision, at least one iteration of the following steps: constructing a set of feedback symbols from the feedback data; obtaining, from the set of feedback symbols, at least one data representative of a feedback decoded signal, called feedback decoded data; computing the at least one feedback decoded data as a function of the at least one predetermined criterion, delivering the feedback data.

Abstract: An arrangement is described in which phase parity or phase opposition between two signals can be determined, and if necessary remedial action may be taken.
