Abstract: Adaptive selection of antenna configurations by wireless nodes that comprise a plurality of antenna elements adapted for a plurality of different antenna configurations. The selection of the antenna configuration is made based on the quality of signal(s) received by the wireless node. The wireless nodes are operable for communication in the mm-wave frequency band and, in specific embodiments, the different antenna configurations include two or more of a wide-coverage area antenna configuration, a Multiple-Input Multiple-Output (MIMO) configuration and a Beamforming (BF) configuration.

Abstract: A method for antenna selection, performed by a user equipment, UE, in a wireless communication system includes determining signal performance of a signal received by the UE. The signal is received by an array antenna of the UE for communication with a network node of the wireless communication system. The method includes determining a signal decay rate associated with the signal performance of the signal, and replacing the array antenna with an omni-directional antenna of the UE for communication with the network node, based on the signal decay rate. Related devices are also described.

Abstract: A method includes receiving (402) a plurality of reference signals (301-303) at an antenna port of a communication device (101). Each reference signal (301-303) is sent using a corresponding precoder. The precoder is selected from a first set of precoders. The method further includes determining (403) a channel estimate based on the received plurality of reference signals (301-303), and selecting (404) a precoder from a second set of precoders based on the determined channel estimate. The second set of precoders comprises at least one precoder in addition to the precoders of the first set of precoders. The method includes sending (405) an indication (304) relating to the selected precoder.

Abstract: A device (112, 130) is configured to communicate data (108) on a radio channel (101, 105, 106) according to a radio access technology. The radio access technology comprises pilot signals and transmission blocks for the data (108). The device (112, 130) is further configured to participate in the radar probing (109) employing at least some of the pilot signals as radar probe pulses of the radar probing (109).
