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： The present solution relates to a method in a first communication node (201) for determining an indication of channel quality of a radio channel (205) between the first communication node (201) and a second communication node (203). The first communication node (201) and the second communication node (203) are comprised in a wireless communication network (200). The radio channel (205) comprises a plurality of sub bands. First, at least two channel quality reports are obtained (701) for different time instances. Each channel quality report comprises indications of channel quality of at least two of the plurality of sub bands. Then a channel quality deviation is estimated (702) for at least one of the plurality of sub bands. Further, an indication of a channel quality is determined (703) for at least one of the plurality of sub bands based on the estimated channel quality deviation.

摘要： The present invention relates to methods and arrangements in a wireless communication system that enable the allocation of resources to UEs based on measurements of their antenna polarization, in order to suppress the interference between different UEs at a very low overhead cost. This is achieved by a solution where the scheduling unit retrieves information about the polarization of the UE antenna configurations, and based on this information allocates radio resources to the different UEs, with the aim to minimize the interference. The scheduling unit may retrieve the information from the RBSs or from the UEs. The RBS and the UE will determine the polarization and transmit information regarding this polarization to the scheduling unit. The scheduling unit coordinates the allocation of resources with other scheduling units if necessary.

摘要： The present invention relates to a method and a transceiver device in a wireless communication system that enable tuning of the polarization generated by a cross-polarized transmitting antenna configuration of an eNB. This is addressed by a solution where the polarization is adjusted (320) based on a quality indicator e.g. received (310) from one or more UEs. The quality indicator indicates the quality of the communication between the eNB and the UEs, and is used to determine if the adjustment of the antenna configuration is improving the quality of the communication or not. The tuning is thus an iteration (330) of the steps of adjusting (320) the polarization and of receiving (310) the quality indicator, and when the quality indicator has reached a pre-determined value, the iteration is stopped.

摘要： The present invention relates to an antenna arrangement for use in a wireless communication system, where the arrangement comprises at least two single-polarized antenna functions. Each antenna function is adapted for radiating an antenna radiation lobe pattern having a horizontal extension in an azimuth plane, and a vertical extension in an elevation plane, perpendicular to the azimuth plane. The antenna functions both have a first polarization in a first direction. In a second direction separated from the first direction, the second antenna function has a second polarization and the first antenna function has a third polarization, the second polarization and the third polarization being orthogonal to each other.

摘要： The present invention relates to a node in a wireless communication system, the node having a central point and comprising at least two antenna functions. Each antenna function is arranged to cover a corresponding sector area, the sector areas being positioned around the central point successively such that each sector area is adjacent to at least one other sector area separated by corresponding borders. The polarization of at least one of said antenna functions is variable between the borders of the corresponding sector area such that for each border, the polarizations of the antenna functions at each side of the border are essentially orthogonal at the border. The present invention also relates to a corresponding wireless communication system and corresponding antenna functions.
