Abstract: Systems, methods, apparatuses, and computer program products for probabilistic amplitude shaping (PAS) are provided. One method may include selecting a distribution parameter for one constellation in a communications system depending on one or more flat fading channels, transforming a uniform distribution of the constellation into a shaped distribution using the selected distribution parameter to produce modulated data, and passing the modulated data through a fading channel

Abstract: An uplink non-orthogonal multiple access for narrowband machine type communication used for the deployment of Internet of Things (IoT) interconnected devices where one or more user equipment are configured for uplink transmission with one or more uplink time-frequency regions for enhanced Machine Type Communication Non-Orthogonal Multiple Access. The configuring is based on defining and signaling one or more signal thresholds and one or more of a resource assignment, a starting subframe periodicity, a starting subframe offset, a time duration in each period, a demodulation reference signal cyclic shift assignment, orthogonal cover code assignment, and interleaver assignment.

Abstract: Various techniques are provided for communicating a request for channel prior information associated with another entity, receiving the channel prior information, predicting a beam for communication between the UE and the network device based on the channel prior information and using a machine learning beam prediction model, indicating channel state information-reference signal (CSI-RS) resource information from a CSI-RS resource table based on the predicted beam, and communicating selected CSI-RS resource information.

Abstract: A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.

Abstract: A method including determining a cyclic redundancy check (CRC) generator sequence defining a one to one mapping between a sequence of control information values and cyclic redundancy check (CRC) sequence values; and determining a combined sequence, the combined sequence formed by distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values, wherein the distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values is based on a selected part of the cyclic redundancy check (CRC) generator sequence.

Abstract: Systems, methods, apparatuses, and computer program products for switching beams on/off for high altitude platform stations (HAPS) are provided. One method may include selecting a beam on/off pattern from one or more beam on/off patterns for a high altitude platform station (HAPS) and a rotation period for the beam on/off pattern, based at least on flight information of the high altitude platform station (HAPS) and user equipment (UE) traffic load information. The method may also include transmitting, to one or more user equipment (UEs), an indication of beam switching on/off operation comprising at least one of the selected beam on/off pattern, a pattern rotation speed, and a reference time slot for a start of the selected beam on/off pattern. The method may then include initiating the beam switching on/off operation.
