摘要： The invention relates to a method for reducing interference between users in a mobile communications network (1) in which uplink transmissions from user equipment, UE (3), to a radio base station, RBS (5A, 5B), can be performed on at least two different carriers (C1, C2). The UE (3) support dynamic switching between CDM and TDM transmission mode and the RBS (5A, 5B) is arranged to dynamically set the mode of transmission for the UE (3). The method comprises the steps of: - identifying (S200) at least a first UE as a high data rate, HDR, UE currently requiring high data transmission rate; dedicating (S201) at least one of said at least two carriers (C1, C2) to said HDR UE for at least a first period of time (T), said at least one carrier (C1, C2) hereinafter being named clean carrier, and - allocating (S202) said at least first HDR UE to said clean carrier (C1, C2) during said at least first period of time (T). This method ensures that no UE operating in CDM mode is transmitting on the same carrier at the same time as the HDR UE.

摘要： The invention relates to adjusting the shape of the antenna beam (20) of a directional antenna (120) in a communications system (1). According to the invention, the antenna beam (20) is divided into at least a handover beam sector (24) and a main beam sector (22). The shape of the at least two beam sectors (22; 24) are then adjusted based on different requirements and objectives. The shape of handover beam sector (24) is adjusted based on the handover parameter settings of the communications system (1), e.g. by adjusting the angular interval of this handover beam sector (24) based on the parameter settings. Optionally, the shape of the main beam sector (22) is adjusted by maximizing the antenna gain of the directional antenna (120) within this beam sector (22).
