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:
Embodiments of the present disclosure are directed towards devices and methods for discovering and waking up dormant access nodes in cellular networks. In one embodiment, the user equipment may be configured with information to assist in determining a discovery zone of discovery signals transmitted by cells in a network. In some embodiments, the information may include a duration of a discovery zone.

Abstract:
Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may map data symbols to resource elements (REs) of virtual resource blocks (VRBs). The gNB may interleave the data symbols, on a per-VRB basis, to spatial layers of a multi-layer multiple-input multiple-output (MIMO) transmission. The data symbols may be interleaved based on different interleave patterns of VRB indexes for the spatial layers. The gNB may map the interleaved data symbols of the spatial layers to REs of physical resource blocks (PRBs) for orthogonal frequency division multiplexing (OFDM) transmission.

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.
