Abstract:
1. A method for Single Carrier-Frequency-Division Multiple Access (SC-FDMA) Physical Uplink Control Channel (PUCCH) format 2/2a/2b detection, comprising: accepting, at a receiver, a plurality of multicarrier signals, the plurality of multicarrier signals having overlapping carrier frequencies; for each of the plurality of multicarrier signals, performing a single tap measurement of a time delay using a Direction of Arrival (DoA) technique by building statistics for slot pairs, comprising data and pilot signal from each antennas in each slot; performing a back-end processing operation based on a number of users representing a number of network devices associated with user entities and at least one of the plurality of multicarrier signals; and detecting PUCCH 2/2a/2b format signals.
