US 2018/0027516 A1 · EVOLVED NODE-B AND USER EQUIPMENT AND METHODS FOR OPERATION IN A COVERAGE ENHANCEMENT MODE

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.

Claims20

Dependent claims

An apparatus of an Evolved Node-B (eNB), the apparatus comprising:

processing circuitry, configured to:
determine a plurality of mapped resource elements of a physical downlink shared channel (PDSCH), for transmission of a system information block (SIB) to a user equipment (UE) configured for enhanced coverage, the mapped resource elements to repeat periodically in sets of frames, wherein one or more channel state information reference signals (CSI-RS) occupies one or more of the mapped resource elements;
and
configure the eNB to transmit, during an enhanced coverage sub-frame, the SIB within the plurality of mapped resource elements of the PDSCH;
and
memory, configured to store data of the SIB.
