When a UE in a first cell operating at a first frequency attempts to discover another UE in a second cell operating at a second frequency, the UE in the first cell may need to constantly monitor communication on the second frequency to discover the UE in the second cell, which may not be desirable. According to an aspect of the disclosure, the apparatus receives, on a first frequency of a first channel from a first base station serving a first cell, discovery information associated with a second frequency of a second channel corresponding to a second cell, wherein the first frequency is a downlink (DL) frequency and the second frequency is an uplink (UL) frequency. The apparatus discovers, based on the received discovery information, one or more UEs on the second frequency of the second channel. |
