    Abstract: Embodiments are provided for supporting variable sub-carrier spacing and symbol duration for transmitting OFDM or other waveform symbols and associated cyclic prefixes. The symbol duration includes the useful symbol length and its associated cyclic prefix length. The variable sub-carrier spacing and symbol duration is determined via parameters indicating the sub-carrier spacing, useful symbol length, and cyclic prefix length. An embodiment method, by a network or a network controller, includes establishing a plurality of multiple access block (MAB) types defining different combinations of sub-carrier spacing and symbol duration for waveform transmissions. The method further includes partitioning a frequency and time plane of a carrier spectrum band into a plurality of MAB regions comprising frequency-time slots for the waveform transmissions. The MAB types are then selected for the MAB regions, wherein one MAB type is assigned to one corresponding MAB region.

    Abstract: A communication method and apparatus. A set of signal outputs includes one or more reference signals including a primary reference signal defined based on a configuration parameter. The reference signals are defined to eliminate phase distortion of the primary reference signal without impacting the peak to average power ratio of a signal waveform. The primary reference signal is transmitted at a time p. The set of signal outputs may also include a second reference signal transmitted at a time p+1, and a third reference signal transmitted at a time p−1. The power level of the primary reference signal may be boosted without impacting the peak to average power ratio of the signal waveform. The primary reference signal may be a first real reference signal replacing imaginary traffic at time p or a first imaginary reference signal replacing real traffic at time p.

    Abstract: System and method embodiments are provided for enabling flexible and reliable UE-to-UE based relay. The embodiments include using fountain codes for combining signals at a suitable network layer higher than a media access control (MAC) sub-layer and using a MAC sub-layer hybrid automatic repeat request (HARQ) transmission scheme. When a relay UE in a UE group for joint reception receives, from a network access point, a data packet intended for a destination UE in the UE group and including fountain code at the higher network layer, the relay UE sends the data packet to the destination UE and returns a HARQ ACK message at the MAC sub-layer to the access point. The destination UE then receives and decodes the data packet. Subsequently, upon receiving the entire data, the destination UE sends an ACK message at the higher network layer to the access point.
