The disclosed systems, structures, and methods are directed to a multiple-input multiple-output (MIMO) receiver. The MIMO receiver includes at least two receiver antenna elements to receive radiated MIMO signal beams containing superposed order modes and to generate antenna element output signals based on the received MIMO signal beams. The receiver antenna elements are spatially separated by a distance. A variable ratio combining unit operates to switch between the antenna output signals based on a high-rate periodic waveform that emulates unidirectional movement by the antenna elements to produce a pseudo-Doppler frequency shift. The variable ratio combining unit further modulates the antenna output signals based on the periodic waveform to impart a fractional pseudo-Doppler shift to each MIMO mode and combines the modulated antenna element output signals in accordance with the fractional pseudo-Doppler shift to facilitate separation of the MIMO modes.

Various solutions with respect to multi-transmission and receiving points (TRP) and multi-panel transmission in wireless communications are described. A processor of a user equipment (UE) associated with a single media access control (MAC) entity receives signaling from a plurality of network nodes of a wireless network. The processor generates at least one feedback responsive to receiving the signaling. The processor transmits the at least one feedback to at least one network node of the plurality of network nodes.

According to embodiments described herein, a long delay-detector improves delay estimation performance for PRACH for many practical deployment scenarios. This, for example, reduces the risk that the timing advance of the UE is set incorrectly and hence reduces the risk that subsequent communication fails and that the UE spreads unnecessary interference to other communication in the system.
