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: A method of determining a lower bound on users' speed for efficient SRS resource handling for MU-MIMO transmission includes determining an eNodeB (eNB) or gNodeB (gNB) timing of a subframe; determining a User Equipment (UE) timing of the subframe; calculating a timing advance type corresponding to a Round Trip Time (RTT); calculating a distance to a base station corresponding to the Round Trip Time (RTT); calculating a distance traveled by a UE between two points based on the distance to the base station; calculating a user speed based on the distance traveled by the UE; deriving a lower bound based on the user speed; and filtering users that exceed the lower bound on user speed. The filtered users may be not assigned SRS. The non-filtered users may be assigned SRS and may subsequently be sent MU-MIMO transmissions.

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).
