Abstract
According to a first aspect there is presented a method for synchronization in a wireless device-to-device (D2D) based communications network as performed by a first wireless device. The method comprises identifying an attempt to make a network connection on a default sub-channel over a D2D communications interface from a second wireless device. The method comprises transmitting control information on the default sub-channel to the second wireless device, wherein the control information comprises an indicator of an operational sub-channel, and wherein the operational sub-channel is for subsequent D2D communication between the first wireless device and the second wireless device.
Claims32
A method for synchronization in a wireless device-to-device (D2D) based communications network, the method being performed by a first wireless device, comprising:
- identifying an attempt for network connection on a default sub-channel over a D2D communications interface from a second wireless device;
- and
- transmitting control information on said default sub-channel to said second wireless device, wherein said control information comprises an indicator of an operational sub-channel that is available for subsequent D2D communication between the first wireless device and the second wireless device.
A method for synchronization in a wireless device-to-device (D2D) based communications network, the method being performed by a second wireless device, comprising:
- performing an attempt to make a network connection on a default sub-channel;
- and
- receiving control information on said default sub-channel from at least one of a network node or a first wireless device, wherein said control information comprises an indicator of an operational sub-channel that is available for subsequent D2D communications with said first wireless device.
A wireless device for synchronization in a wireless device-to-device (D2D) based communications network, the wireless device comprising a processing unit configured to:
- identify an attempt to make a network connection on a default sub-channel over a D2D communications interface from a second wireless device;
- and
- transmit control information on said default sub-channel to said second wireless device, wherein said control information comprises an indicator of an operational sub-channel that is available for subsequent D2D communication between the first wireless device and the second wireless device.
A wireless device for synchronization in a wireless device-to-device (D2D) based communications network, the wireless device comprising a processing unit configured to:
- perform an attempt to make a network connection on a default sub-channel;
- and
- receive control information on said default sub-channel from at least one of a network node or a first wireless device, wherein said control information comprises an indicator of an operational sub-channel that is available for subsequent D2D communications with said first wireless device.
A non-transitory processor readable storage medium comprising a computer program for synchronization in a wireless device-to-device (D2D) based communications network, the computer program comprising computer program code which, when run on a processing unit of a first wireless device causes the processing unit to:
- identify an attempt to make a network connection on a default sub-channel over a D2D communications interface from a second wireless device;
- and
- transmit control information on said default sub-channel to said second wireless device, wherein said control information comprises an indicator of an operational sub-channel that is available for subsequent D2D communication between the first wireless device and the second wireless device.
A non-transitory processor readable storage medium comprising a computer program for synchronization in a wireless device-to-device (D2D) based communications network, the computer program comprising computer program code which, when run on a processing unit of a second wireless device causes the processing unit to:
- perform an attempt to make a network connection on a default sub-channel;
- and
- receive control information on said default sub-channel from at least one of a network node or a first wireless device, wherein said control information comprises an indicator of an operational sub-channel that is available for subsequent D2D communications with said first wireless device.
