Abstract

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.

Description

technical field [0001] Embodiments described herein generally relate to a radio network node and a method in a radio network node. What is described herein is, inter alia, a mechanism for wireless signal communication in a multi-antenna environment. Background technique [0002] Some mobile communication systems provide high data rates using Multiple-Input Multiple-Output (MIMO) multi-antenna systems. [0003] Massive MIMO (MMIMO) is a recently emerging technology that uses a large antenna array system (AAS) with individual transceivers connected to one or more antenna elements to improve the throughput of wireless communication systems. Massive MIMO systems are also sometimes referred to as "very massive MIMO systems" or "massive antenna systems". [0004] Antenna arrays with a large number of antenna elements and transceivers are used in both downlink and uplink to increase capacity by exploiting the high spatial resolution enabled by beamforming and spatial multiplexing...
