摘要： Error vector magnitude (EVM) is pooled and adaptively distributed among carriers in a multi-standard or multi-carrier system to reduce peak to average power ratios (PAPR) without exceeding EVM limits. Correction tone injection is used to reduce PAPR. The amplitude of each correction tone, and number of correction tones assigned to a carrier, are adjusted to control the EVM and out-of-band distortion of each carrier, to comply with EVM limits imposed by the respective radio access technology.

摘要： A wireless communication node (10) dynamically estimates passive intermodulation (PIM) interference coupled into the node's receive path from the transmission of a composite signal through the node's transmit path. The node (10) then cancels the estimated PIM interference in the receive path. In some embodiments, the node dynamically estimates the PIM interference as a function of the composite signal that models PIM interference generation and coupling in the node (10) according to one or more coefficients (30). The coefficients (30) may be determined by transmitting a test signal (34) during a test stage, when the node (10) is not scheduled to receive any signal. Later, when the composite signal (18) is transmitted, the node (10) uses the coefficients (10) to dynamically estimate and cancel the resulting PIM interference.

摘要： Method and arrangement in a serving base station for determining a binary value of information data received from a user equipment, by using a supportive likelihood value received from a supporting base station. The user equipment transmits information data to be received both by the serving base station and the supporting base station. The method comprises: decoding information data bits received from the user equipment into a first likelihood value, without determining a binary value for each bit of the information data, a supportive likelihood value of the information data bits transmitted from the user equipment is received from the supporting base station, which supportive likelihood value is based on a decoding of the information data bits performed in the supporting base station. The first likelihood value of the decoded information bits is combined with the received supportive likelihood value of the decoded information bits. Thus a binary value for each bit of the information data transmitted from the user equipment is determined, based on the combined first and supportive likelihood values.

摘要： A method and an arrangement (1100) are provided in a communication node for enabling reduction of peaks (302) in transmitted signals. In the method, a sample representing a peak in a signal is selected (202), and a tone frequency, an amplitude and a phase shift are determined (204-208) and are used to create (210) a correction signal which is added (214) to the original signal if it is found (212) to reduce the peak. The procedure is repeated from the operation of selecting a sample representing a peak as long as a stop criterion is not fulfilled (218).

摘要： A method of wirelessly transmitting control information includes generating control information comprising a plurality of control bits and encoding the control bits using a block code that outputs an encoded bit sequence comprising encoded bits b(0), b(1),..., b(19). The control bits are encoded using the block code by generating a linear combination of a plurality of basis sequences. The method also includes dividing the encoded bits into a first group and a second group. The first group includes the encoded bits {b(0), b(1), b(5), b(6), b(8), b(11), b(12), b(14), b(17), b(19)} and the second group includes the encoded bits {b(2), b(3), b(4), b(7), b(9), b(10), b(13), b(15), b(16), b(18)}. Additionally, the method includes transmitting the first group of encoded bits on a first set of carriers and transmitting the second group of encoded bits on a second set of carriers. The second set of carriers have different frequencies from the first set of carriers.
