Abstract: A technology for device to device (D2D) communication scheduling is disclosed. A D2D device can be synchronized with a base station of a cellular system. A sub-frame symbol boundary can be identified in the cellular system for the D2D communication. A resource for a D2D communication can be allocated from the D2D device to another D2D device within the sub-frame boundary of the cellular system. The D2D device can be switched to perform a D2D communication with another D2D device in proximity with the D2D device, wherein the other D2D device is substantially synchronized with the base station of the cellular system. The D2D device can communicate with the other D2D device within at least one symbol boundary time within the selected subframe.

Abstract: Apparatuses and methods for Non-Orthogonal Multiple Access (NOMA) communication are discussed. An example Evolved NodeB (eNB) includes a memory, a processor, and a transmitter circuit. The processor evaluates an orthogonal multiple access (OMA) metric and a NOMA metric, generates a protocol instruction that indicates an OMA transmission or a NOMA transmission based on the metrics, and determines a first modulation and coding scheme (MCS) for a first UE and a second MCS for a second UE. The transmitter circuit receives the protocol instruction and transmits a first data signal and a first downlink control information (DCI) message associated with the first UE, and a second data signal and a second DCI message associated with the second UE. When the protocol instruction indicates NOMA transmission, the data signals are power multiplexed, the DCI messages indicate the data signals are transmitted via NOMA, and the first DCI message indicates the second MCS.

Abstract: Methods and apparatus are described for transmitting uplink control information (UCI) over an OFDMA-based uplink. In some embodiments, UCI symbols are mapped to resource elements (REs) in the time/frequency resource grid to maximize frequency diversity. In some embodiments, UCI is mapped in a manner that takes into account channel estimation performance by mapping UCI symbols to those REs that are closest (in terms of OFDM subcarriers/symbols) to REs that carry reference signals.

Abstract: Techniques are described for compressing the PUCCH resources reserved for acknowledging downlink data transmissions when those resources are implicitly signaled by EPDCCHs that schedule the downlink transmissions in TDD mode. An acknowledgment resource offset field transmitted in the EPDCCH is configured to correspond to one or more values that compress the region in PUCCH resource index space that would otherwise be reserved for the subframes of a bundling window.

Abstract: Embodiments pertain to systems, methods, and component devices for dynamic non-orthogonal multiple access (NOMA) communications. A first example embodiment includes user equipment (UE) configured to receive a first downlink control indicator (DCI) from an evolved node B (eNB) and process the first subframe as a first higher power NOMA subframe in response to a first power ratio signal. The DCI includes the first power ratio signal for a first NOMA subframe. The UE may then receive, from the eNB, a second DCI, the second DCI comprising a second power ratio signal for a second subframe and process, by the UE, the second subframe as a second lower power NOMA subframe in response to the second power ratio signal. Additional embodiments may further use another DCI with a third power ratio signal to configure the UE to receive orthogonal multiple access (OMA) communications.

A device may determine one or more high efficiency signal fields of a high efficiency preamble, wherein at least one of the one or more high efficiency signal fields includes at least in part a common field and one or more user specific fields. The device may determine a resource allocation index associated with the one or more user specific fields. The device may determine a partition of the one or more user specific fields between a first subfield of the at least one of the one or more high efficiency signal fields and a second subfield of the at least one of the one or more high efficiency signal fields based at least in part on the resource allocation index. The device may cause the one or more high efficiency signal fields to be wirelessly transmitted to one or more devices over a wireless communication channel.
