Abstract
Methods and apparatus for addressing wireless transmit/receive unit (WTRU) behavior in response to configuration, configuration parameters and access issues related to the activation/deactivation process when the WTRU may be configured with multiple serving cells or carrier aggregation.
Claims53
A method implemented at a wireless transmit/receive unit (WTRU) for supporting carrier aggregation, the method comprising:
- establishing a connection with a primary cell (PCell);
- receiving, at the WTRU, dedicated signaling including a secondary cell (SCell) configuration of a SCell, wherein the SCell configuration includes a radio resource configuration and an identity of the SCell, and wherein the radio resource configuration identifies configuration parameters for both downlink (DL) and uplink (UL) resources of the SCell;
- configuring the configuration parameters into the WTRU, wherein the identity of the SCell is an index to the configuration parameters;
- maintaining, at the WTRU, a state of the SCell;
- and
- utilizing at least one of DL resources and UL resources of the SCell based on a the of the SCell.
A wireless transmit/receive unit (WTRU) configured for supporting carrier aggregation, comprising:
- a transmitter, a receiver and a processor in communication with the transmitter and receiver, wherein the processor is configured to:
- establish a connection with a primary cell (PCell);
- receive dedicated signaling including a secondary cell (SCell) configuration of a SCell, wherein the SCell configuration includes a radio resource configuration and an identity of the SCell, and wherein the radio resource configuration identifies configuration parameters for both downlink (DL) and uplink (UL) resources of the SCell;
- configure the configuration parameters into the WTRU, wherein the identity of the SCell is an index to the configuration parameters;
- maintain a state of the SCell;
- and
- utilize at least one of DL resources and UL resources of the SCell based on a state of the SCell.
A method implemented at a wireless transmit/receive unit (WTRU) for supporting carrier aggregation, the method comprising:
- establishing a connection with a primary cell (PCell);
- receiving, at the WTRU, dedicated signaling including a secondary cell (SCell) configuration for a SCell;
- configuring the WTRU in accordance with the SCell configuration;
- processing an activation/deactivation command for the SCell;
- and
- triggering a power headroom report on condition that the SCell has configured uplink resources and on condition that the state of the SCell is an active state.
