    Abstract: A method includes receiving a two-bit information stream comprising first and second bits and performing precoding using the two-bit information stream to determine multiple output signals. The precoding is performed to create a finite multiple of states for the output signals. The output signals comprise a first output signal based on a version of the first input bit and on a version of a second input bit, a second output signal based on a delayed version of the first input bit and the version of the second input bit, and a third output signal based on the version of first input bit and a delayed version of the second input bit. The method includes performing pulse shaping of each of the output signals to create pulse-shaped signals, combining the pulse-shaped signals to create a transmission waveform, and outputting the transmission waveform. Apparatus, computer programs, and computer program products are disclosed.

    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: Various communication systems may benefit from efficient communication of system information. For example, certain wireless communication systems may benefit from system information block enhancement for low complexity user equipment and/or user equipment in coverage enhancement mode. A method can include decoding a transport block size (TBS) index in a compact downlink control information. The method can also include monitoring for SIB based on the decoded TBS index. The method may optionally include monitoring for the SIB based on a predefined transmission pattern of physical downlink control channel for machine type communication. The method may also optionally include decoding of M-SI messages from a subframe according to a pattern indicated by an information element in M-SIB1.
