Abstract
Aspects of the present disclosure provide a plurality of discovery reference signal (DRS) search modes implemented by the user equipment (UE) during contention-based communication in an unlicensed spectrum. The plurality of DRS search modes may include a first DRS search mode ('Full search mode'), second DRS search mode ('Comb search mode'), and a third DRS search mode (“Thin search mode”). The DRS search modes may be selected by the UE based on the system requirements (e.g., tradeoffs between robustness and complexity against cycle cost). Features of the present disclosure further provide techniques for dynamically switching between the plurality of DRS search modes in order to minimize power consumption while reducing the number of cycles required to locate the DRS.
