METHOD AND NODE IN A WIRELESS COMMUNICATION NETWORK

摘要

Radio network node (110) and method (900) therein, for communication in a wireless communication system (100). The radio network node (110) comprises: a plurality of an- tenna elements (210-1, 210-2, …, 210-n), forming an antenna array (210); a plurality of transceivers (220-1, 220-2, …, 220-n), each transceiver (220-1, 220-2, …, 220-n) coupled to at least one dedicated antenna element (210-1, 210-2, …, 210-n) of the antenna array (210); and a controller (230) configured to adjust a first subset of the transceivers (220-1, 220-2, …, 220-n) to work at a first frequency band (310), and to adjust a second subset of the transceivers (220-1, 220-2, …, 220-n) to work at a second frequency band (320). The first subset of transceivers (220-1, 220-2, …, 220-n) and the second subset of transceivers (220-1, 220-2, …, 220-n) are disjoint and configured to operate at their respective fre- quency bands (310, 320) simultaneously.
