Abstract
A method of handling TAGs in a UE capable of CA is disclosed. The method comprises monitoring time differences between signals received from any two serving cells and determining for each time difference whether a configured capability of the UE supports the time difference. A wireless telecommunication device and a computer program are also disclosed.
Claims13
A method of handling timing advance groups (TAGs) in a user equipment (UE) configured to support carrier aggregation (CA), the method comprising:
- determining a capability of the UE for supporting time differences between signals received from any two serving cells, wherein said determining is based on how many carriers are configured for CA and on an aggregated bandwidth for CA;
- monitoring time differences between signals received from any two serving cells;
- determining, for each time difference, whether the UE supports the time difference, based on the determined capability.
A wireless telecommunication device arranged to operate in a wireless telecommunication network supporting carrier aggregation (CA), wherein the device is configured to support CA, the device comprising:
- a receiver;
- and
- one or more processing circuits configured to:
- determine a capability of the device for supporting time differences between signals received from any two serving cells, wherein said determining is based on how many carriers are configured for CA and on an aggregated bandwidth for CA;
- monitor time differences between signals received from any two serving cells;
- and
- determine, for each time difference, whether the device supports the time difference, based on the determined capability.
A non-transitory computer-readable medium comprising, stored thereupon, a computer program comprising instructions that, when executed on a processor of a communication apparatus configured to support carrier aggregation (CA), causes the communication apparatus to perform the following:
- determine a capability of the communication apparatus for supporting time differences between signals received from any two serving cells, wherein said determining is based on how many carriers are configured for CA and on an aggregated bandwidth for CA;
- monitor time differences between signals received from any two serving cells;
- and
- determine, for each time difference, whether the communication apparatus supports the time difference, based on the determined capability.
