    Abstract: This disclosure describes methods, apparatus, and systems related to a high efficiency signal field load balancing system. 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.

    Abstract: A user equipment (UE) may communicate channel state information in a wireless network. The UE may include transceiver circuitry to receive orthogonal frequency division multiple access (OFDMA) signals from an Enhanced node B (eNB). The UE may include processing circuitry to derive one or more principal eigen beams from the received OFDMA signals. The principal eigen beams may have a rank greater than or equal to one. The processing circuitry may derive quantized eigen beams from the principal eigen beams. The processing circuitry may select, in response to the quantized eigen beams, a subset of available antenna ports on the eNB for receiving from the eNB and transmitting to the eNB. The UE may communicate to the eNB a bit pattern of the quantized eigen beams and at least one of a wideband channel quality indicator (CQI) or a subband CQI conditioned on the quantized eigen beams.

    Abstract: Embodiments of User Equipment (UE), an Evolved Node-B (eNB), and methods for channel quality indicator (CQI) feedback are disclosed herein. An aperiodic CQI type parameter received at the UE may indicate a CQI type for use in a determination of an aperiodic CQI based on signals received from the eNB. Channel-state information reference signals (CSI-RS) may be used when single-user multiple-input multiple-output (SU-MIMO) signals are received. Physical downlink shared channel (PDSCH) blocks may be used when multi-user multiple-input multiple-output (MU-MIMO) signals are received. The aperiodic CQI may be transmitted to the eNB as part of an aperiodic CQI measurement report. In addition, periodic CQI measurement reports may also be transmitted to the eNB and may include periodic CQIs that are based on CSI-RS received at the UE.

    Abstract: Provided herein are method and apparatus for beam recovery. An embodiment provides an apparatus for a user equipment (UE) including a radio frequency (RF) interface; and processing circuitry configured to: determine, in response to a beam failure, a channel for transmission of a beam failure recovery request as one of: a Physical Uplink Control Channel (PUCCH), a non-contention based Physical Random Access Channel (PRACH), and a contention based Physical Random Access Channel (PRACH); and encode the beam failure recovery request for transmission to an access node via the determined channel using the RF interface. At least some embodiments allow for transmission of a beam failure recovery request for beam recovery, allow for beam failure detection or new Tx beam identification, and allow for determining whether to configure a scheduling delay between a PDCCH and a PDSCH.

    Abstract: Described is an apparatus of an Evolved Node-B (eNB) comprising a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to generate a reference signal transmission for an eNB Transmitting (Tx) beam corresponding with at least a first eNB antenna port having a first polarization and a second eNB antenna port having a second polarization. The second circuitry may be operable to process one or more reporting transmissions carrying at least one of a first signal reception indication for a first UE antenna port and a second signal reception indication for a second UE antenna port. The third circuitry may be operable to determine a transmission hypothesis based upon the one or more reporting transmissions.

    Abstract: Disclosed herein are apparatuses, systems, and methods for reference signal design for initial acquisition, by receiving a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS) from a first transmit (Tx) beam, in first contiguous orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A UE can receive at least a second PSS and a second SSS from a second Tx beam in contiguous OFDM symbols of the downlink subframe. A UE can then detect beamforming reference signals (BRSs) corresponding to the first Tx beam and the second Tx beam, based on identification of physical cell ID information and timing information processed from the first PSS, the second PSS, the first SSS, and the second SSS. The UE can select the first Tx beam or the second Tx beam that was received with the highest power, based on the BRSs. Other embodiments are described.
