Wireless device and method therein for determining a search space in a wireless communications network

Abstract:

A method performed by a wireless device for determining a search space for a physical control channel in a wireless communications network is provided. The wireless device is configured with a first search space of a physical control channel which first search space is associated with a first synchronization signal. The wireless device attempts to receive the first synchronization signal from a first network node. The wireless device then determines a search space for a physical control channel based on whether or not the attempt to receive said first synchronization signal was successful. When the attempt to receive said first synchronization signal was successful determining a first search space for the physical control channel, and when the attempt to receive said first synchronization signal was not successful determining a second search space for any one or more out of: the physical control channel and a second physical control channel.
