POWER HEADROOM REPORTING FOR MTC DEVICES IN ENHANCED COVERAGE MODE

摘要

The present disclosure relates various embodiments for improving power headroom reporting for UEs being in an enhanced coverage mode. The UE may be configured to always transmit a virtual power headroom report to the eNB, when operating in the enhanced coverage mode. Or, the UE may be configured to always transmit a virtual power headroom report to the eNB, when operating in the enhanced coverage mode and at the same time being power limited. Moreover, the UE may determine a repetition level for transmissions in the uplink and/or may determine a repetition level for transmissions in the downlink. The power headroom report can then be used to transport this information (either one of, or both of, the uplink/downlink repetition levels), by using predefined codepoints in the power headroom report.
