Patent ID: 10736112

Abstract:
Methods, systems, and devices for wireless communications are described. In some wireless networks (e.g., MulteFire networks), a base station may transmit control information to a user equipment (UE) to enable the UE to access the network and establish a connection with the network. The base station may transmit the control information to the UE in search spaces of an enhanced physical downlink control channel (ePDCCH). In some cases, resources used to transmit control information in a first common search space of the ePDCCH may overlap with resources used to transmit control information in a second common search space of the ePDCCH. In such cases, using the techniques described herein, a base station may encode control information transmitted in the different types of search spaces using different scrambling sequences. As such, a UE may be able to differentiate between the control information transmitted in the different types of common search spaces.
