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 base station may transmit downlink control information (DCI) scheduling communications between the base station and a UE. The DCI is in a fallback DCI format. Based on whether or not the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE ID of the UE, data transmitted by the base station or by the UE according to the DCI may be scrambled by a sequence that is initialized with a configurable parameter, or initialized with a cell ID.

Abstract: Systems and methods of synchronization channel design for radio access network (RAN) slicing are described. According to embodiments, a user equipment (UE) receives, from a first transmit point in a radio access network (RAN), a first synchronization signal over a first synchronization channel. The first synchronization channel is associated with a first RAN slice of a plurality of RAN slices in the RAN. The plurality of RAN slices comprise a second RAN slice associated with a second synchronization channel. The first synchronization channel and the second synchronization channel are different from a default synchronization channel of the first transmit point.
