    Abstract: Embodiments of the present invention include a system for transmitting a precoding codebook over an air interface. The system includes a first station configured to signal a set of indicators via at least one antenna to a second station from which the precoding codebook is derived at the second station based on the signaled set of indicators. The set of indicators includes less information than the precoding codebook.

    Abstract: The invention relates to a method for joint processing of uplink data (g(n), s(n)) transmitted from at least one user equipment (UE1, UE2) to a plurality of coordinated reception points (BSA, BSB) of a wireless communication system (1), the method comprising: estimating and preferably compensating for individual propagation delays of the uplink data (g(n), s(n)) transmitted from one of the user equipments (UE1, UE2) to the coordinated reception points (BSA, BSB), and compensating a timing difference between a propagation delay of a coordinated reception point (BSA, BSB) which serves the user equipment (UE1, UE2) and at least one propagation delay of at least one coordinated reception point (BSB, BSA) which does not serve the user equipment (UE1, UE2) for performing the joint processing of the uplink data (g(n), s(n)), wherein the step of compensating the timing difference comprises modifying a channel matrix (H) associated with uplink channels from the at least one user equipment (UE1, UE2) to the coordinated reception points (BSA, BSB). The invention also relates to a processing arrangement (BSA, BSB, 2) adapted for performing the method.

    Abstract: The invention relates to a method for interference reduction in a radio communication system. The method (MET1) contains the steps of receiving (M1/6) at a processing unit (PU) from at least one mobile station (MS1) indications of radiation beams (B1, B2, B3, B4) that are transmitted by a first base station (BS1) of the radio communication system and that fulfill or exceed a predefined quality criterion at the at least one mobile station, when the at least one mobile station (MS1) is attached to the first base station (BS1) and when the at least one mobile station (MS1) is located within a first overlapping coverage area of the first base station (BS1) and of a second base station (BS2) of the radio communication system, and determining (M1/10) at the processing unit (PU) at least one radio resource to be unused or to be transmitted with a limited transmission power by the first base station (BS1) for at least one of the radiation beams (B1, B2, b3, B4) based on the received indications for serving the at least one mobile station (MS1) or at least one further mobile station (MS2) by the second base station (BS2) with the at least one radio resource. The invention further relates to a processing unit (PU) and to a wireless access network node, which contains the processing unit (PU).
