Abstract
There is provided a method for performing communication related to inter-band CA. The method is performed by a wireless communication device. The wireless communication device may receive cell information from a PCell. The cell information may include first information that the PCell is collocated with a SCell within a base station or second information that the PCell is not collocated with the SCell. The PCell and the SCell are configured for the inter-band CA. The wireless communication device may perform communication with at least one of the PCell and the SCell.
Claims13
A method for performing communication related to inter-band carrier aggregation (CA), the method performed by a wireless communication device and comprising:
- transmitting capability information about a beam management type for the inter-band CA of a wireless communication device;
- and
- performing communication with the wireless communication device with both of a Primary Cell (PCell) and a Secondary Cell (SCell),
- wherein the SCell and the PCell use different operating bands for the inter-band CA,
- wherein the communication with both of the PCell and SCell is performed based on a relative receive timing difference between a first receive timing from the PCell and a second receive timing from the SCell,
- wherein the relative receive timing difference does not exceed a maximum receive timing difference (MRTD),
- wherein the MRTD is set based on a combination of frequency range for the PCell and frequency range for the SCell, and
- wherein the MRTD is applied based on that the beam management type for the inter-band CA is independent beam management, for a combination that frequency range for both of the PCell and SCell is frequency range 2 (FR2).
A wireless communication device in wireless communication system, the wireless communication device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- transmitting capability information about a beam management type for the inter-band CA of a wireless communication device;
- and
- performing communication with the wireless communication device with both of a Primary Cell (PCell) and a Secondary Cell (SCell),
- wherein the SCell and the PCell use different operating bands for the inter-band CA,
- wherein the communication with both of the PCell and SCell is performed based on a relative receive timing difference between a first receive timing from the PCell and a second receive timing from the SCell,
- wherein the relative receive timing difference does not exceed a maximum receive timing difference (MRTD),
- wherein the MRTD is set based on a combination of frequency range for the PCell and frequency range for the SCell, and
- wherein the MRTD is applied based on that the beam management type for the inter-band CA is independent beam management, for a combination that frequency range for both of the PCell and SCell is frequency range 2 (FR2).
