Abstract: A reference signaling scheme is provided that is based on the use of a Zadoff Chu sequence with cyclic repetition, optionally code division multiplexing precoding, together with frequency domain spectral shaping (FDSS). A specific pulse shape design for the FDSS part of the reference signal scheme in some embodiments involves the use of a raised cosine pulse raised to the power of β. The new solution for generating reference signals has a Low peak average power ratio that matches the PAPR of SC-OQAM, good channel estimation performance, and the ability to implement CDM in the frequency domain to increase multiplexing gain.

Abstract: Systems and methods for detecting potentially active user equipment (UE) in a network are provided. A set of potentially active UEs is detected using an iterative method. In a first iteration UE detection is performed using compressed sensing (CS) based on first pilot sequences to detect a first set of potentially active UEs. Channel estimation is then performed for the first set of potentially active UEs. In subsequent iterations, UE detection is performed using CS to detect another set, typically reduced in size, of potentially active UEs using results of the channel estimation from the previous iteration. Channel estimation is then again performed for the new set of potentially active UEs. After the last iteration, the set of potentially active UEs detected in the last iteration is output as the determined set of potentially active UEs along with channel estimates for the set of potentially active UEs determined in last iteration.

Abstract: Control signaling in multiple access communication systems, including apparatus and methods, is disclosed. Multiple access to a wireless communication link is based on power modulation division. Modulation information, capacity information, resource scheduling information, and resource assignment information is determined by a base station. Information is transmitted to user equipment devices in a common control channel in accordance with the determined modulation information, capacity information and resource scheduling information. Information is also transmitted to supporting user equipment, which supports the power modulation division multiple access, in a user equipment-specific control channel in accordance with the determined resource assignment information.

Abstract: A two-phase approach to machine-type communications is provided. In a first phase, for activity detection, at least one symbol is transmitted using a long signature. During a second phase, for data transmission, information-carrying symbols are transmitted using a short spreading signature. Activity detection performance is enhanced through the use of a longer spreading signature.

Abstract: A system and method of DFT-S-OFDM modulation is provided that uses a set of frequency domain patterns. For a given transmitter, for a set of DFT-S-OFDM symbols, the frequency domain pattern changes according to a time domain hopping pattern. Advantageously, the time domain hopping patterns are defined to allow only a certain amount of overlap, for example for only one DFT-S-OFDM symbol, between any two time domain hopping patterns. This functions to reduce the effect of a collision, when two transmitters use the same frequency pattern, they will do so only for part of the overall transmission. Optionally, frequency domain spectral spreading is used in the transmitter. This can further reduce the PAPR. In the receiver, successive interference cancellation may be employed to reduce the effect of colliding transmissions.

Abstract: Current frame structures in Long-Term Evolution (LTE) and New Radio (NR) place some restrictions on the symbols transmitted in the frame, e.g. restrictions related to the duration of each symbol. Embodiments are disclosed in which multi-carrier symbols and/or single-carrier symbol blocks have configurable parameters, such as configurable length and/or configurable location, thereby allowing for more flexibility in the scheduling and transmission of the symbols and/or symbol blocks. Some embodiments aim to implement the configurable parameters in a way that tries to reduce signaling overhead.

Abstract: Methods and systems are disclosed for symbol sequence generation and transmission for non-orthogonal multiple access (NoMA) transmission. A NoMA signal may be generated based on: (1) a first symbol sequence, the first symbol sequence determined from a set of input bits and associated with a first MA signature within a first MA signature space; (2) a second symbol sequence determined based on the first symbol sequence, the second symbol sequence being associated with a second MA signature within a second MA signature space; and (3) a symbol-to-resource element mapping applied to the second symbol sequence to produce the NoMA signal.
