1. A method for receiving a power saving signal, applied to a terminal device and comprising:
in a case that a beam failure is detected, transmitting a random access request; and
after the random access request is transmitted and before a transmission control indication TCI state is updated, performing detection for a first power saving signal in a recovery search space based on a first quasi co-location QCL relationship, wherein the first power saving signal may be used to determine whether to wake up in OnDuration and the first QCL relationship is a QCL relationship of beam failure recovery reference signals BFR-RS.
