Abstract: Various communication systems may benefit from rerouting considerations. For example, fifth generation (5G) systems dealing with radio link failure detection and data rerouting, particularly mmWave 5G systems, may benefit from rapid rerouting methods and systems. A method can include transmitting, from an access point, a downlink control message to a user equipment. The method can also include attempting to detect a Fast-ACK transmission signal from the user equipment in response to the transmitted downlink control message. The method can further include transmitting a rerouting request for the user equipment when the Fast-ACK transmission signal is not detected.

Abstract: Systems, methods, apparatuses, and computer program products for random access channel (RACH) with a grid of beams for communication systems are provided. One method includes transmitting, by a base station, a beacon signal in one time slot with multiple switched beams, wherein the beams cover an intended coverage area with a grid-of-beams in both horizontal and vertical directions. The method may also comprise switching receiving beams in the grid-of-beams at a network reserved random access channel (RACH) slot by following an identical or directly related beam switching pattern in a downlink (DL) beacon channel. Another method includes detecting, by a user equipment, a beam ID in the downlink beacon channel, selecting the RACH slot using the detected beam ID, and transmitting, by the user equipment, a random access channel (RACH) signature in one or multiple beam blocks within a random access channel (RACH) slot.

Abstract: Systems, methods, apparatuses, and computer program products for an interleaved multi-beam acquisition waveform providing concurrent beam selection, automatic gain control (AGC) and automatic frequency correction (AFC) are provided. The access point (AP) may send an acquisition waveform on multiple beams, then return and retransmit an AFC on the multiple beams thus interleaving beam switching with the acquisition and frequency correction waveforms. AGC correction can be deferred until the end, relying on the fact that the transmitter may be detected at close range using a one of the multi-beams that is attenuated.
