Abstract: Techniques for improving CSI (Channel State Information) in connection with FD (Full Dimension)-MIMO (Multiple Input Multiple Output) are discussed. A first set of techniques can employ hierarchical cell common class B CSI-RS for improved beam selection. A second set of techniques can provide improved CSI feedback based on eigenvalue(s) and co-phase associated with a precoder. Various embodiments can employ either or both of the first set of techniques and/or the second set of techniques.

Abstract: An apparatus of a user equipment (UE) may include a memory and one or more processors operatively coupled to the memory. The processors may process a scheduling trigger to provide channel state information (CSI) and beam information using extra-large physical uplink shared channel (xPUSCH). The processing device may also generate a reporting message comprising CSI and beam information. The processing device may then encode xPUSCH data to include the reporting message.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing a control channel (PDCCH) design. The PDCCH can occupy an initial number of OFDM symbols of a downlink subframe, while occupying less than the full system bandwidth. The PDCCH can be time division multiplexed (TDM) with a shared channel (PDSCH) or frequency division multiplexed (FDM) with a PDSCH. The PDCCH can further be multiplexed with another PDCCH in a contiguous or non-contiguous region. Resources allocated to the PDCCH can overlap or partially overlap resources allocated to the PDSCH. An Evolved Node-B (eNB) can provide configuration information for the PDCCH design in Radio Resource Control (RRC) signaling to a user equipment (UE), or through use of a Master Information Block (MIB) or System Information Block (SIB).

Abstract: Devices and methods of simultaneous data reception and measurement are generally described. A UE transmits to an eNB antenna capacity and receives a Beamformed Reference Signal (BRS) configuration in response. Beamformed signals from the eNB include a BRS subframe in accordance with the BRS configuration. The BRS subframe has a BRS whose structure depends on the UE antenna capacity. If the UE has a single antenna panels, neither an EPDCCH nor a PDSCH for the UE is in the BRS frame. If the UE has a single antenna panels and multiple ports or multiple antenna panels, the BRS may contain an EPDCCH or PDSCH for the UE as different ports or antenna panels may be assigned different functionality. The UE measures BRS Received Power (BRS-RP) of the BRS, transmits a BRS report based on the BRS-RP and selects an optimal beam based on BRS-RPs from BRSs of the beams.

Abstract: Devices and methods of providing symmetric UL and DL ACK/NACKs is generally described. UL ACK/NACKs of different UEs are multiplexed and received by a UE with a PUSCH. The receiving UE in response transmits the DL ACK/NACK. The ACK/NACK may be transmitted in a localized or distributed manner among subbands that may be adjacent or each may have blocks separated by blocks of a different subband. The ACK and NACK may use independent resources or the NACK may not be transmitted on the single ACK/NACK resource, the lack of an ACK serving as a NACK. The ACK/NACK may be transmitted using a beamforming weight shaped by the received PUSCH/PDSCH. The ACK/NACK symbol may be located in the first symbol, adjacent to the PUSCH/PDSCH, or at the end of a TTI. If adjacent, the UL grant or UL assignment may indicate whether the ACK/NACK resource is used by the PUSCH/PDSCH.

Abstract: Technology for decreasing latency for contention based scheduling request (SR) transmission is disclosed. A user equipment (UE) can process, for transmission to an enhanced node B (eNB), a DeModulation Reference Signal (DM-RS) that is randomly selected from a set of configured DM-RS sequences or configured by the eNB. The UE can select an SR transmission resource as a function of a DM-RS sequence index or cell identification (ID) based on a predefined mapping rule. The UE can process, for transmission to the eNB, a SR message having a buffer status report (BSR) and UE identification (UE-ID) information on the selected SR transmission resource.
