Power headroom reporting for MTC devices in enhanced coverage mode
Abstract:
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.
