Abstract
A first base station transmits, to a second base station and after making a handover decision for a wireless device, a first message. The first message comprises at least one parameter indicating the wireless device supports configuration of a plurality of cell groups. The first base station receives from the second base station a second message comprising first configuration parameters of a plurality of cells grouped into a first plurality of cell groups comprising a first cell group and a second cell group. The first base station transmits, to the wireless device, a third message comprising the first configuration parameters.
Claims20
A method comprising:
- transmitting, by a first base station to a second base station and after making a handover decision for a wireless device, a first message comprising at least one parameter indicating the wireless device supports configuration of a plurality of cell groups;
- receiving from the second base station at least one second message comprising first configuration parameters of a plurality of cells grouped into a first plurality of cell groups comprising a first cell group and a second cell group, wherein:
- uplink transmission timing in the first cell group is derived employing a first cell in the first cell group;
- and
- uplink transmission timing in the second cell group is derived employing a second cell in the second cell group;
- and
- transmitting, to the wireless device, a third message comprising the first configuration parameters.
A first base station comprising:
- one or more processors;
- and
- memory storing instructions that, when executed, cause the first base station to:
- transmit, to a second base station and after making a handover decision for a wireless device, a first message comprising at least one parameter indicating the wireless device supports configuration of a plurality of cell groups;
- receive from the second base station at least one second message comprising first configuration parameters of a plurality of cells grouped into a first plurality of cell groups comprising a first cell group and a second cell group, wherein:
- uplink transmission timing in the first cell group is derived employing a first cell in the first cell group;
- and
- uplink transmission timing in the second cell group is derived employing a second cell in the second cell group;
- and
- transmit, to the wireless device, a third message comprising the first configuration parameters.
A method for use in a wireless network, the method comprising:
- transmitting, by a first base station to a second base station and after making a handover decision for a wireless device, a first message comprising at least one parameter indicating the wireless device supports configuration of a plurality of cell groups;
- receiving, by the first base station from the second base station, at least one second message comprising first configuration parameters of a plurality of cells grouped into a first plurality of cell groups comprising a first cell group and a second cell group, wherein:
- uplink transmission timing in the first cell group is derived employing a first cell in the first cell group;
- and
- uplink transmission timing in the second cell group is derived employing a second cell in the second cell group;
- and
- receiving, by the wireless device from the first base station, a third message comprising the first configuration parameters.
