Abstract: A Passive Optical Networks (PONs) structure and a remote node in such a structure constituting at least a part of a backhaul network for supporting a Radio Access Network, in which a number of radio base stations are connected to optical networks units (ONUs) of said PONs structure. The ONUs of said PONs structure are grouped between separate PONs of said PONs structure. The ONUs of a separate PON are interconnected passively through a remote node of the PON in order to separate inter base station traffic of X2 interfaces from uplink and downlink data traffic of S1 interface heading from/to a core network via an optical line terminal (OLT). The remote node comprises of power splitter for enabling interconnection between ONUs of different PONs of said PONs structure.

Abstract: Wireless communication systems are provided including a transmitter and a receiver. The transmitter is configured to transmit a first polarized signal and a second polarized signal to the receiver, and in accordance with an instruction from the receiver, halt transmission of the second polarized signal. The receiver is configured to receive the polarized signals from the transmitter, determine whether or not the reception quality of the second polarized signal is below a threshold, and if so, instruct the transmitter to halt transmission of the second polarized signal.
