Abstract
The present application relates to devices and components including apparatus, systems, and methods for carrier aggregation operations in wireless communication systems.
Claims19
One or more non-transitory computer-readable media having instructions that are to be executed to cause processing circuitry to:
- determine, by a user equipment (UE), that configuration information for a secondary serving cell (SCell) does not include an absolute frequency synchronization signal block (SSB) (absoluteFrequencySSB) parameter;
- identify a command to activate the SCell;
- determine, based on determination that the configuration information does not include the absolute FrequencySSB parameter, a first reference signal of the SCell is associated with a second reference signal of an active serving cell that is on a same band as the SCell;
- and
- activate the SCell based on determination that the first reference signal is associated with the second reference signal.
2 more elements
A method comprising:
- detecting a capability of a user equipment (UE) to support secondary serving cell (SCell) operation without synchronization signal and physical broadcast channel block (SSB) (scellWithoutSSB);
- determining, based on the capability of the UE, that the UE supports scellWithoutSSB;
- generating configuration information for an SCell based on the capability, wherein the configuration information does not include an absolute frequency SSB (absoluteFrequencySSB) parameter for the SCell;
- and
- generating an activation command for the SCell to be transmitted to the UE.
2 more elements
An apparatus comprising:
- processing circuitry configured to:
- determine, by a user equipment (UE), that configuration information for a secondary serving cell (SCell) does not include an absolute frequency synchronization signal block (SSB) (absoluteFrequencySSB) parameter;
- identify a command to activate the SCell;
- determine, based on determination that the configuration information does not include the absoluteFrequencySSB parameter, a first reference signal of the SCell is associated with a second reference signal of an active serving cell that is on a same band as the SCell;
- and
- activate the SCell based on determination that the first reference signal is associated with the second reference signal;
- and
- memory interface circuitry, coupled with the processing circuitry, to store the configuration information in memory.
