Abstract
A wireless device receives configuration parameters of timing advance groups (TAGs) comprising: a primary TAG comprising a primary cell; and a secondary TAG comprising one or more licensed secondary cells and one or more unlicensed secondary cells. Uplink signals are transmitted via the secondary TAG. The transmission timing is derived employing a first secondary cell, of the secondary TAG, that is based on the first secondary cell being: an activated secondary cell; and a licensed secondary cell.
Claims20
A method comprising:
- receiving, by a wireless device, configuration parameters of timing advance groups (TAGs) comprising:
- a primary TAG comprising a primary cell;
- and
- a secondary TAG comprising one or more licensed secondary cells and one or more unlicensed secondary cells;
- and
- transmitting uplink signals via the secondary TAG with transmission timing derived employing a first secondary cell, of the secondary TAG, that is based on the first secondary cell being:
- an activated secondary cell;
- and
- a licensed secondary cell.
6 more elements
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive configuration parameters of timing advance groups (TAGs) comprising:
- a primary TAG comprising a primary cell;
- and
- a secondary TAG comprising one or more licensed secondary cells and one or more unlicensed secondary cells;
- and
- transmit uplink signals via the secondary TAG with transmission timing derived employing a first secondary cell, of the secondary TAG, that is based on the first secondary cell being:
- an activated secondary cell;
- and
- a licensed secondary cell.
9 more elements
A system comprising:
- a base station comprising:
- one or more first processors;
- and
- first memory storing first instructions that, when executed by the one or more first processors, cause the base station to transmit configuration parameters of timing advance groups (TAGs) comprising:
- a primary TAG comprising a primary cell;
- and
- a secondary TAG comprising one or more licensed secondary cells and one or more unlicensed secondary cells;
- and
- a wireless device comprising:
- one or more second processors;
- and
- memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
- receive the configuration parameters;
- and
- transmit uplink signals via the secondary TAG with transmission timing derived employing a first secondary cell, of the secondary TAG, that is based on the first secondary cell being:
- an activated secondary cell;
- and
- a licensed secondary cell.
