Abstract:
1. An antenna arrangement comprising: at least two antennas for providing radio coverage to a plurality of user equipment in a predetermined area of a mobile communications network, the at least two antennas being arranged to have different vertical properties to thereby provide at least two different areas of radio coverage within the predetermined area, and there being provided a plurality of frequencies for use in the predetermined area; wherein the antenna arrangement is configured to dynamically adjust transmission properties of at least one of the antennas based on a distribution of users within the predetermined area and frequency requirements for users within the predetermined area, to dynamically allocate at least one user equipment to at least one group associated with at least one of the at least two antennas based on link characteristics of a user equipment, and dynamically allocate at least one of said plurality of frequencies to said at least one group, and wherein different frequencies are assigned to different sectors of the coverage area, wherein the different frequencies are assigned to different antennas and multiple antennas are configured to use different frequencies allocated to a shared sector.
