Methods, systems, and devices for wireless communication are described. The described techniques provide for transmitting, at a base station, a contention exempt broadcast paging message that includes partial paging information for a user equipment (UE), receiving a random access request message transmitted by a UE in response to the broadcast paging message, and transmitting a unicast paging message which includes complete paging information. The described techniques further provide for determining, at a base station, a first paging opportunity window (POW) and a second POW for a UE, performing a LBT procedure during the first POW, transmitting a broadcast paging message including partial paging information for the UE during the first POW, performing a second LBT procedure during the second POW, transmitting a unicast paging message to the UE during the second POW, the unicast paging message including complete paging information for the UE.
