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 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:
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:
Described is an apparatus of an eNB operable to communicate with a UE on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may be operable to process a first transmission carrying a DM-RS antenna port group indicator and a second transmission carrying an antenna port configuration indicator. The second circuitry may be operable to select a DM-RS antenna port group comprising a set of antenna port configurations based upon the DM-RS antenna port group indicator. The third circuitry may be operable to select an antenna port configuration out of the set of antenna port configurations based upon the antenna port configuration indicator, the antenna port configuration comprising one or more DM-RS antenna ports. The fourth circuitry may be operable to process a third transmission carrying DM-RS in accordance with the selected configuration.
Abstract:
Provided herein are method and apparatus for beam recovery. It provides an apparatus for a UE (101) including a radio frequency (RF) interface; and processing circuitry configured to: determine beam quality for one or more BPLs between the UE (101) and an access node (111,112); and in response to the beam quality for all of the BPLs being below a first predetermined threshold, encode Physical Random Access Channel (PRACH) data to include a beam recovery request that identifies a candidate beam of the access node (111,112); determine a transmit power for the beam recovery request; and send the PRACH data to the RF interface for transmission to the access node (111,112) with the transmit power. At least some embodiments allow for determining a transmission power to transmit a PRACH, to ensure reception of the PRACH, and allow for determining whether to use a PRACH or a PUCHH.
