Method for transmitting and receiving downlink channel and device therefor
The present invention discloses a method for receiving, by means of a terminal, a downlink channel in a wireless communication system. In particular, the method may receive information about a plurality of component carriers, transmit information related to power consumption of a component carrier group including at least one first component carrier among the plurality of component carriers, and receive a downlink channel through at least one second component carrier activated on the basis of the information related to power consumption.
1. A method for receiving a downlink channel by a user equipment (UE) in a wireless communication system, the method comprising:
receiving information related to a plurality of component carriers (CCs);
transmitting information related to power consumption of each of a plurality of CC groups, each CC group including at least one of the plurality of CCs; and
receiving the downlink channel through a CC determined based on the information related to the power consumption,
wherein, for a CC group including a deactivated CC, the UE calculates the power consumption of the CC group based on an assumption that a predetermined bandwidth part (BWP) of the deactivated CC is activated for receiving the downlink channel.
2. The method of claim 1 , wherein the information related to the power consumption includes values obtained by measuring a power consumption level for a specific number of resource blocks (RBs).
3. The method of claim 1 , wherein the same CC group is associated with the same radio frequency (RF) circuit.
4. The method of claim 1 , wherein the UE is capable of communicating with at least one of anther UE, a network, a base station, and an autonomous driving vehicle.
5. An apparatus for receiving a downlink channel in a wireless communication system, the apparatus comprising:
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
receiving information related to a plurality of component carriers (CCs);
transmitting information related to power consumption of each of a plurality of CC groups, each CC group including at least one of the plurality of CCs; and
receiving the downlink channel through a CC determined based on the information related to the power consumption,
wherein, for a CC group including a deactivated CC, the apparatus calculates the power consumption of the CC group based on an assumption that a predetermined bandwidth part (BWP) of the deactivated CC is activated for receiving the downlink channel.
6. The apparatus of claim 5 , wherein the information related to the power consumption includes values obtained by measuring a power consumption level for a specific number of resource blocks (RBs).
7. The apparatus of claim 5 , wherein the same CC group is associated with the same radio frequency (RF) circuit.
8. The apparatus of claim 5 , wherein the apparatus is capable of communicating with at least one of a user equipment (UE), a network, a base station, and an autonomous driving vehicle.
9. A user equipment (UE) for receiving a downlink channel in a wireless communication system, the terminal 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, when executed by the at least one processor, perform operations comprising:
receiving information related to a plurality of component carriers (CCs) through the at least one transceiver;
transmitting, through the at least one transceiver, information related to power consumption of each of a plurality of CC groups, each CC group including at least one of the plurality of CCs; and
receiving, through the at least one transceiver, the downlink channel through a CC determined based on the information related to the power consumption,
wherein, for a CC group including a deactivated CC, the UE calculates the power consumption of the CC group based on an assumption that a predetermined bandwidth part (BWP) of the deactivated CC is activated for receiving the downlink channel.
10. The method of claim 1 , wherein the predetermined BWP is determined based on higher layer signaling.
11. The method of claim 1 , wherein the predetermined BWP is a lowest indexed BWP in the deactivated CC.
12. The method of claim 1 , wherein the predetermined BWP is a largest BWP in the deactivated CC.
13. The method of claim 1 , wherein the predetermined BWP is an initial BWP in the deactivated CC.
