Abstract: Disclosed is a method for analog beamforming performed by a transmitter (110) of a wireless communication network (100). The transmitter (110) comprises a plurality of antenna branches (114, 115, 116), each antenna branch comprising an antenna element (111, 112, 113). The method comprises, for each antenna branch (114, 115, 116), obtaining a first and a second signal of an analog radio signal, the first and the second signal being split from the analog radio signal and the analog radio signal being the same at each of the antenna branches, and obtaining information indicating a branch-specific phase-shift angle and a branch-specific amplitude determined from information identifying a radiation pattern comprising at least two directions for wireless transmission to at least one receiver (120).

Abstract: Disclosed is a transmitter configured for analog beam steering, the transmitter comprising a plurality of antenna branches, each having an antenna (326). The transmitter comprises, at each of the antenna branches, a signal splitter (308) for splitting an analog radio signal into a number of beam signals, the number of beam signals equals a number of desired beams to be transmitted. Further, the transmitter comprises, for each of the number of beam signals, a phase shifter (310, 312) for phase shifting the beam signal according to a phase shift setting for that beam and for that antenna branch, the phase shift settings being taken from a single look-up table, and a signal combiner (314) for combining the phase shifted beam signals into one combined signal. Further, the transmitter is arranged for transmitting the combined signal from the antenna (326) of that antenna branch towards a receiver.

Abstract: In an example embodiment, a system comprises a chain of serially coupled nodes, including a central processing node (CPN) and one or more radio communications nodes (RCNs). The CPN couples to a first RCN in the chain via a dielectric waveguide (DWG) link and any further RCNs in the chain are successively connected in serial fashion from the first RCN via further (DWG) links. The CPN generates outbound radio carrier signals that are waveguide-propagated in a downstream direction of the chain, for over-the-air (OTA) by targeted ones of the RCNs, while radio carrier signals received via OTA reception by respective ones of the RCNs are waveguide propagated as inbound radio signals in an upstream direction of the chain, for processing by the CPN. Advantages from he contemplated system include greatly simplified implementation of the RCNs, with lower cost and power consumption. Further, strategic placement of failover CPNs and DWG links provide for continued operation in the face of CPN or DWG link failures.
