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 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 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： A method is disclosed for use in a heterogeneous telecommunications system of the kind comprising a macro base station and a low-power base station, the low-power base station having a coverage which is extendible by range expansion, RE, to serve a user equipment which would otherwise have been served by the macro base station. According to the method, which is performed in either of the macro base station or the low-power base station, information about radio conditions of the user equipment at least with respect to the macro base station is obtained (310). Based on the obtained information, it is determined (320) whether a criterion for conditional range expansion is satisfied, said criterion being related to the uplink transmission power of the user equipment to the macro base station. Accordingly, range expansion is applied (330) for the user equipment only when the criterion is satisfied. A corresponding base station, telecommunications system and computer readable storage medium are also disclosed.
