1. A method for wireless communications, comprising:
- monitoring, at a user equipment (UE) over an unlicensed radio frequency spectrum band, for a discovery signal from a network entity on a downlink control channel, wherein the discovery signal comprises a synchronization signal and an enhanced system information block (eSIB) comprising timing information corresponding to a non-periodic current subframe location of the network entity in at least one or more of a system information block 1 (SIB1), a system information block 2 (SIB2), or a master information block (MIB);
receiving the discovery signal during a subframe from the network entity;
determining the non-periodic current subframe location of the network entity based on the discovery signal; and
demodulating the downlink control channel based on the non-periodic current subframe location.
