Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic resource allocation (DRA) of resources for machine-type communication (MTC), as a secondary partition within a system bandwidth. Allocations outside the secondary partition are configured as a primary partition for other than MTC. Apparatuses may perform MTC communications within the secondary partition when DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC. Otherwise, if the apparatus is other than MTC, the apparatus may refrain from performing communications in the secondary partition. Other embodiments are described.

Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

Abstract: Devices for and methods of providing low latency 5G FDD communications are generally described. A HARQ ACK/NACK for an xPDSCH is transmitted in the xPUCCH of the same or next subframe as the xPDSCH and xPDCCH. An xPUSCH is generated in the same subframe in response to an xPDCCH and HARQ ACK/NACK response is carried by another xPDCCH or xPHICH in the same or next sub frame. The xPDCCH and the xPUCCH are at opposite ends of the same subframe, DL and UL subframe are delayed relative to each other, or at least one of the DL and UL subframe has an additional blank portion, portion with data associated with another UE or portion that contains a reference signal, broadcast signal or control information.

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: Briefly, in accordance with one or more embodiments, apparatus of an evolved NodeB (eNB) comprises circuitry to configure one or more parameters for a 5G master information block (xMIB). The xMIB contains at least one of the following parameters: downlink system bandwidth, system frame number (SFN), or configuration for other physical channels, or a combination thereof. The apparatus of the eNB comprises circuitry to transmit the xMIB via a 5G physical broadcast channel (xPBCH) on a predefined resource, the xPBCH comprising a xPBCH. The xPBCH may use a DM-RS based transmission mode, and a beamformed xPBCH may be used for mid band and high band.

Abstract: Technology for an eNodeB to communicate with a user equipment (UE) using a self-contained time division duplex (TDD) subframe within a wireless communication network is disclosed. The eNodeB can process, for transmission to the UE, a DL self-contained time division duplex (TDD) subframe comprising an extended physical downlink shared channel (xPDSCH), an extended physical downlink control channel (xPDCCH), a downlink (DL) spacing signal, and a guard period, wherein the xPDSCH, the xPDCCH, the DL spacing signal, and the guard time are located within the DL self-contained TDD subframe prior to an extended physical uplink control channel (xPUCCH). The eNodeB can process, an uplink (UL) self-contained TDD subframe, received from the UE, having a UL spacing signal located after an extended physical uplink shared channel (xPUSCH).
