Abstract: Aspects relate to technologies and techniques for sequence-based, non-coherent wireless channel transmission of a payload on a physical uplink channel. A transmitter converts information bits of a payload to be transmitted to a decimal integer value that is, in turn, used to generate a modified maximum sequence (m-sequence) based on one or more predetermined parameters such as an m-sequence generating polynomial, a starting location in the sequence, and an initialization. The generated modified m-sequences are modulated using modulation schemes such as π/2 binary phase-shift keying and quadrature phase-shift keying for transmission on the physical uplink channel.

Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR, over the Rayleigh fading channel. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

Abstract: Methods and apparatuses for beam determination in random access in a wireless communication system a method performed by a user equipment (UE) includes receiving a system information block (SIB) indicating a first number of spatial settings, a set of random access channel occasions (ROs), and a set of numbers of repetitions for transmission of a physical random access channel (PRACH). The method further includes determining a number of repetitions, from the set of numbers of repetitions, for the PRACH transmission, a subset of ROs, from the set of ROs, corresponding to the number of repetitions, and a set of spatial settings having a one-to-one association with the subset of ROs based on a mapping between the first number of spatial settings and a number of ROs in the subset of ROs. The method further includes transmitting the PRACH over the subset of ROs using the set of spatial settings.

Abstract: Communication systems are described that use unequally spaced constellations that have increased capacity compared to conventional constellations operating within a similar SNR band. One embodiment is a digital communications system including a transmitter transmitting signals via a communication channel, the transmitter including a coder capable of receiving user bits and outputting encoded bits at a rate, a mapper capable of mapping encoded bits to symbols in a constellation, and a modulator capable of generating a modulated signal for transmission via the communication channel using symbols generated by the mapper, wherein the constellation is unequally spaced and characterizable by assignment of locations and labels of constellation points to maximize parallel decode capacity of the constellation at a given signal-to-noise ratio so that the constellation provides a given capacity at a reduced signal-to-noise ratio compared to a uniform constellation that maximizes the minimum distance between constellation points of the uniform constellation.

Abstract: Reliability, in 5G and emerging 6G, is a continuing challenge due to signal fading, heavy interference, and phase noise, among others. The disclosed procedures show how to locate the most likely faulted message elements according to a deviant modulation, excessive amplitude or phase instability, and inconsistency between successive transmissions of the message. In addition, the receiver can rectify the message either by altering the faulted message elements to other modulation states, or by selectively merging two versions of the message according to signal quality. In either case, reliability is improved, range is extended, and time is saved.

Abstract: A first station (STA) receives a first frame indicating a capability of a second STA to receive a first number of repetitions of a first signal field of a Physical Layer Protocol Data Unit (PPDU), where the first number of repetitions comprises more than two. The first STA encodes the PPDU such that the first signal field comprises up to the first number of repetitions based on the capability of the second STA. The first STA transmits, to the second STA, the PPDU, based on the encoding.

Abstract: In various examples, systems and methods of wireless communication link adaptation are described. In some examples, first data may be determined for a first gateway device, the first data representing a plurality of received signal strength (RSS) values of a first signal received from a first end node device. Second data representing an interference associated with the first signal may be determined. At least one of a first packet error rate or a first packet success rate may be determined based at least in part on the first data and the second data. A first modulation coding scheme (MCS) associated with at least one of the first packet error rate or the first packet success rate may be determined. Third data may be sent to the first end node, the third data instructing the first end node device to use the first MCS for communication with the first gateway device.
