Enhanced node B (ENB) and method for MTC coexistence
First Claim
1. An evolved Node B (eNB) configured to communicate with a User Equipment (UE) on a licensed band, the eNB comprising circuitry configured to:
- transmit a physical downlink control channel (PDCCH) transmission on the licensed band;
transmit, to the UE, a machine-type communication (MTC) system information block (M-SIB), the M-SIB including configuration information to configure a MTC region of the licensed band, wherein the MTC region includes a subset of frequencies of the licensed band, wherein the MTC region has a bandwidth of 1.4 MHz or less;
transmit, to the UE, resource allocation information in a MTC downlink control channel of the MTC region, the MTC downlink control channel being time multiplexed with the PDCCH;
transmit, to the UE, a channel state information reference signal (CSI-RS) within the MTC region;
rate-match the resource allocation information around resource elements for the CSI-RS to avoid collisions between the CSI-RS and transmissions in the MTC region;
transmit, to the UE, first data transmission on the MTC region in a downlink; and
receive, from the UE, a second data transmission on the MTC region in an uplink.

Abstract
Embodiments of a machine-type communication (MTC) User Equipment (UE) and methods for configuring a MTC UE using an evolved Node B (eNB) are generally described herein. A method for configuring a UE for communication performed by circuitry of an evolved Node B (eNB) may include broadcasting, from the eNB, a physical downlink control channel (PDCCH) transmission on a licensed band, transmitting, from the eNB to the UE, a physical broadcast channel (PBCH) transmission multiplexed with a machine-type communication (MTC) PBCH (M-PBCH) transmission, the M-PBCH transmission including a MTC master information block (M-MIB) in a MTC region of the licensed band, wherein the MTC region includes a subset of frequencies of the licensed band, and transmitting, from the eNB to the UE, a first data transmission on the MTC region in a downlink.
