Abstract: A method and apparatus for multi-tier beamforming are disclosed. The method includes receiving a first-tier beamformed frequency-domain IQ data packet and a plurality of second-tier beamformed frequency-domain IQ data packets at a transceiver integrated circuit (IC) subarray. Each transceiver IC of the transceiver IC subarray (i) forms a multi-tier beamformed frequency-domain IQ data set by combining beamformed frequency-domain IQ data from the first-tier beamformed frequency-domain IQ data packet with beamformed frequency-domain IQ data from selected ones of the second-tier beamformed frequency-domain IQ data packets, (ii) generates a discrete-time-domain signal from the multi-tier beamformed frequency-domain IQ data set, and (ii) generates a modulated radio frequency (RF) signal from the discrete-time-domain signal. The method further includes transmitting a multi-tier beamformed signal by transmitting respective modulated RF signals from the transceiver ICs of the transceiver IC subarray via a corresponding adjacent antenna element subarray.

Abstract: In the case that several transmitting elements (e.g., a Tx chain) are simultaneously impaired, at least two different layouts are possible: the defected Tx chains are randomly scattered around the array; or, the defected Tx chains are aligned vertically on a random column (for 12 and 24 defected Tx chains—1 and 2 such columns are randomly chosen, respectively). It can be seen that the throughput is worse when the defected Tx chains are aligned in a column rather than randomly scattered, unless the defective Tx chains are known, in which case it is the opposite. This is because disabling an entire column has the most significant effect on the spatial null steering. When defected Tx chains are known the performance of all layouts are almost the same, though column yields slightly better results due to the antenna subarrays (2 vertical antennas have the same feed, therefore we lose less degrees of freedom).

Abstract: The disclosed invention presents new approach for FEC implementation as part of existing link between the PHY layer (L1) and MAC layer. In one embodiment a method for providing cellular network Forward Error Correction (FEC) offload, includes merging FEC functionality into the PHY-MAC interface including placing FEC functionality IPs inside a small form factor (SFP) transceiver and allowing configurations from the PHY controller; identifying data carrying packets; encoding/decoding of the data payload; and forwarding an encoded/decoded payload to the next layer.
