Security for downlink signaling

An apparatus for wireless communications at a user equipment (UE), comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors, the one or more memories storing instructions executable by the one or more processors to cause the apparatus to:
• determine a set of parameters for a control resource set from a plurality of sets of parameters, wherein the set of parameters is indicated by an output of a pseudo-random function;
• monitor a set of resources, indicated by the pseudo-random function, within the control resource set for a downlink control channel, wherein the set of resources is based at least in part on an output of the pseudo-random function, and wherein the output of the pseudo-random function is based at least in part on a timing parameter, a cell identifier, and a key;
• and
• communicate with a network entity via a cell associated with the cell identifier based at least in part on monitoring the set of resources for the downlink control channel.

A method of wireless communication at a user equipment (UE), comprising:

• monitoring a set of resources, indicated by a pseudo-random function, for one or more synchronization signal blocks, the one or more synchronization signal blocks associated with one or more pseudo-random sequences, wherein the one or more pseudo-random sequences and the set of resources are indicated by an output of the pseudo-random function that is based at least in part on a timing parameter, a cell identifier, and a key, wherein monitoring the set of resources comprises:
• monitoring for a first burst of synchronization signal blocks, wherein a first ordering of synchronization signal block indexes for the first burst of synchronization blocks is indicated by the output of the pseudo-random function;
• and
• monitoring for a second burst of synchronization signal blocks, wherein a second ordering of synchronization signal block indexes for the second burst of synchronization blocks is indicated by the output of the pseudo-random function, wherein the output of the pseudo-random function indicates the first ordering and the second ordering based at least in part on a quantity of symbols per half-frame;
• and
• communicating with a network entity via a cell associated with the cell identifier based at least in part on monitoring the set of resources for the one or more synchronization signal blocks.
