Abstract
Systems, methods, and instrumentalities are disclosed to describe cell selection in low cost machine type communication (LC-MTC) devices. An LTC-MC device may measure a plurality of downlink signals from a plurality of cells. The LTC-MC may detect a channel condition, e.g., by determining a cell with better uplink coverage than a downlink cell. The detection of the channel condition may include measuring an uplink pathloss. The LTC-MC may report the channel condition as a decoupled channel condition, e.g., when an uplink cell is identified with uplink coverage better than the downlink cell. The channel condition may be reported, e.g., via a set of Physical Random Access Channel (PRACH) preambles. The set of PRACH preambles may be predefined. The channel condition may be reported via a higher layer signaling.
