Patent ID: 10299254

Abstract:
The present disclosure proposes a general method for accessing a network when a wireless device, e.g., a user equipment, knows about a wireless network because it can e.g. measure on a cell and read its system information, but is unable to access it. The disclosure relates to transmitting uplink control messages relating to data received in a wireless device and in particular it relates a method, performed in a wireless device supporting a first radio access technology and a second radio access technology, of transmitting uplink control messages relating to data received in the wireless device. The method comprises receiving a configuration message defining in the first radio access technology, a Physical Fast Control Channel for transmission of uplink control messages relating to data received in the wireless device using the second radio access technology and transmitting uplink control messages relating to data received using the second radio access technology on the Physical Fast Control Channel. The proposed technology also relates to methods of handling and receiving uplink control messages in radio network modules, and to a wireless device and radio networks modules for implementing the methods as well as to corresponding computer programs.
