Abstract: Systems and methods of performing a RACH procedure in a MulteFire scenario are described. An eMTC UE communicates with an eNB on an anchor channel at a predetermined frequency of an unlicensed band and data channels on other frequency hopping channels of the unlicensed band. The UE receives a PBCH signal with System Information Broadcast Anchor (SIB-A-MF) scheduling information, and a SIB-A-MF after the PBCH. The SIB-A-MF indicates a RAC) resource configuration for a RACH procedure and dwell time of the data channels. The dwell time of the anchor channel is smaller than that of the data channels. The anchor channel includes a UL RACH resource for transmission of a RACH Request. The UE transmits UL RACH messages on UL resources indicated by the SIB-A-MF and receives DL RACH messages on different data channels.

Abstract: Embodiments of enabling a secondary cell in a massive MIMO system are generally described herein. An example apparatus of UE may include memory and processing circuitry to configure a MIMO transceiver to establish primary cell transmit and receive channels for communication with an eNodeB, and to receive a secondary cell addition signal that includes a preamble index for a secondary cell. The processing circuitry further configures the MIMO transceiver to receive beam reference signals (BRS), and select one of the BRS from the eNodeB as a secondary cell transmit channel for the secondary cell based on detected BRS receive power. The processing circuitry further configures the MIMO transceiver to provide information for the selected BRS, and provide xPRACH transmissions that include a transmit index to the eNodeB. The processing circuitry further configures the MIMO transceiver to receive selection of one of the xPRACH transmissions as a secondary cell receive channel.

Abstract: An apparatus and method for CSI reporting in the unlicensed band are described. CRS-RSs are transmitted from a RAN in narrowband data channels in the unlicensed band to an eMTC UE. The UE determines the CQI and PMI from the CRS-RSs and transmits a periodic CSI report to the RAN that contains the CQI and PMI. The periodic CSI report is received at a nsfrel th subframe of a nmframeth mframe, where nmframe satisfies nmframe mod Npd,mframe=NOFFSET,mframe where Nmframe is a reporting period in terms of mframes and NOFFSET,mframe is a reporting period offset in terms of mframes, and nsfrel satisfies nsfrel−20=NOFFSET,CQI where NOFFSET,CQI is a reporting period offset in subframes.

Abstract: An apparatus of a user equipment (UE) may include a memory and one or more processors operatively coupled to the memory device. The processors determine a reporting mode for the UE based on a message received at the UE from an eNodeB. The UE may generate a channel state information (CSI) reporting message based on the determined reporting mode. The processors may also encode extra-large physical uplink control channel (xPUCCH) data including the CSI reporting message.

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.
