    Abstract: Embodiments of an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.

    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: Codebook designs are disclosed for full-dimensional multiple-input-multiple output (FD-MIMO) wireless cellular systems. The FD-MIMO cookbooks employ channel state information reference signals (CSI-RS). The codebook designs are used in beamforming CSI-RSs by the enhanced nodeB (eNB), where the CSI-RS is sent to the user equipment (UE), enabling the UE to perform channel estimation. The codebooks support beam selection, co-phasing between polarizations, and beam combining.
