Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a set of time-frequency resources for one or more cell detection signals (CDS) associated with a pseudo-random sequence, where the pseudo-random sequence and the set of time-frequency resources are indicated by an output of a pseudo-random function (PRF) that is based on a timing parameter, a cell identifier (ID), and a shared key. Accordingly, the UE may communicate with a network entity via a cell associated with the cell ID based on receiving the one or more CDS. The UE may also exchange one or more messages with the network entity, and may perform a time calibration procedure based on the one or more messages and a delay threshold of the UE. The one or more messages may indicate an ID of the UE, a cryptographic number, a time interval, or a combination thereof.
