1. A method, performed by a network node in a wireless network, for signaling resynchronization signal, RSS, configurations of neighbor cells to one or more user equipment, UE, the method comprising:
encoding a plurality of parameters of respective RSS configurations of one or more neighbor cells, wherein for each particular neighbor cell:
the plurality of parameters include one or more RSS frequency locations and an RSS time offset for the particular neighbor cell, and
the encoding is based on a bitmap and a parameter associated with the particular neighbor cell; and
wherein encoding the one or more RSS frequency locations of the respective RSS configurations includes, for each particular neighbor cell:
for each of a plurality of narrowbands comprising the particular neighbor cell's carrier bandwidth, determining whether the particular neighbor cell is transmitting RSS within a particular narrowband; and
encoding transmission determinations for the respective narrowbands in respective bits of a bitmap associated with the particular neighbor cell, wherein the bitmap is one of the encoded parameters; and
transmitting, to the one or more UEs, at least a portion of the encoded parameters of the respective RSS configurations of the neighbor cells.
