摘要： Embodiments herein relate to a method in a first communication node (201) for estimating pre-coding weights for transmission on a radio channel (205) between the first node (201) and a second communication node (203) in a communication network (200). The first node (201) comprises at least two transmit antennas. Each transmit antenna is configured to transmit on each of at least two sub-bands. The first node (201) obtains at least two pre-coding reports. Each pre-coding report is for a different time instance. Each pre-coding report comprises pre-coding weights or indications to pre-coding weights. The pre-coding weights are associated with each transmit antenna and with each sub-band. For each transmit antenna, the first node (201) estimates pre-coding weights for at least one of the sub-bands based on the pre-coding weights in the obtained pre-coding reports. The estimated pre-coding weights are different from a most resent of the obtained pre-coding reports.

摘要： An object of the present invention is to enable coordination of VP/HP polarizations generated by cross-polarized, i.e. orthogonally polarized antenna configurations, of one radio device with another radio device. The object is achieved by a method in a first eNB (100c) of coordinating polarizations of the first eNB with polarizations of an additional eNB (100a). The polarizations are generated by an antenna configuration comprising at least two orthogonally polarized antennas. The first and additional eNB (100c, 100a) communicate wirelessly with a UE (150a). The method comprises the steps of establishing a first amplitude and/or phase offset of the antenna configuration generating a vertical or horizontal polarization, and a second amplitude and/or phase offset of the antenna configuration generating a polarization orthogonal to said polarization generated by the first amplitude and/or phase offset, defining the polarization generated by the first amplitude and/or phase offset to be vertical and the polarization generated by the second amplitude and/or phase offset to be horizontal, determining a polarization of the UE, and coordinating the defined polarizations with polarizations of the additional eNB based on the determined UE polarization.
