## Abstract

Embodiments herein may relate to transmission, in a first physical channel transmission, of an indication of a first set of parameters related to a control channel; and transmission, in a control channel transmission using the first set of parameters, of an indication of a second set of parameters related to the control channel. Further embodiments may relate to identifying a first parameter related to interleaving REGBs of a PDCCH transmission, wherein the first parameter is selected from a first plurality of parameters; interleaving the REGBs based on the first parameter to form a CCE, and transmitting die CCE in the PDCCH transmission. Other embodiments may be described and/or claimed.

## Claims

### Claim at position 1

1-25. (canceled)

### Claim 26

A base station comprising:
