Abstract
Presented are systems and methods for configuring component carrier groups. A wireless communication device may determine a first reference signal associated with a second reference signal. The wireless communication device may determine information of a target signal in a first component carrier (CC) according to the first reference signal. The second reference signal may be in a second CC in an activated beam state.
Claims8
A method, comprising:
- receiving, by a wireless communication device, a beam state list comprising a beam state of a target signal in a first component carrier (CC), via a first radio resource control (RRC) signaling in a second CC;
- determining, by the wireless communication device, the second CC as a reference CC according to a second RRC signaling which indicates an index of the second CC;
- determining, by the wireless communication device, a first reference signal in the first CC based on a reference signal (RS) identifier in the beam state of the beam state list that is configured in the second CC;
- determining, by the wireless communication device, first information of the target signal in the first CC according to the first reference signal;
- receiving, by the wireless communication device, a first command comprising an identifier of the beam state activated or indicated from the beam state list;
- determining, by the wireless communication device, based on the first command, that the beam state is applicable to the target signal in the first CC;
- and
- communicating, by the wireless communication device, the target signal in the first CC using the beam state.
