PAGING FOR LOW-POWER WAKE UP FOR A USER EQUIPMENT
Various aspects of the present disclosure relate to paging for low-power wake up for a user equipment. An apparatus, such as a UE, receives a first configuration for calculating one or more low-power radio monitoring occasions and a second configuration for calculating one or more main radio monitoring occasions. The UE can control a low-power radio and a main radio based at least in part on the first configuration and the second configuration.
1 . A base station for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the base station to:
transmit, to a user equipment (UE), a first configuration for calculating one or more low-power radio monitoring occasions and a second configuration for calculating one or more main radio monitoring occasions;
transmit, to the UE, one or more low-power radio paging indications on the one or more low-power radio monitoring occasions; and
transmit, to the UE, one or more main radio paging indications on the one or more main radio monitoring occasions.
2 . The base station of claim 1 , wherein first configuration comprises an indication that the one or more low-power radio monitoring occasions are to be at least a time slot threshold earlier than the one or more main radio monitoring occasions.
3 . The base station of claim 2 , wherein the time slot threshold is configured to enable a low-power radio to wake up a main radio before the main radio is configured to start receiving and transmitting.
4 . The base station of claim 1 , wherein one or more of the first configuration or the second configuration comprises an indication that if the UE is paged on a low-power monitoring occasion, a low-power radio is to wake a main radio.
5 . The base station of claim 1 , wherein one or more of the first configuration or the second configuration comprises an indication that if the UE is not paged on a low-power monitoring occasion, a low-power radio is to wake a main radio.
6 . The base station of claim 1 , wherein one or more of the first configuration or the second configuration comprises an indication that if the UE is paged on a low-power monitoring occasion and paging is not directed to the UE, a low-power radio is not to wake a main radio.
7 . The base station of claim 1 , wherein the at least one processor is configured to cause the base station to:
determine that the UE moves to a different base station; and
transmit one or more of the first configuration or the second configuration to the different base station.
8 . The base station of claim 1 , wherein the at least one processor is configured to cause the base station to transmit one or more of the first configuration or the second configuration to a network function.
9 . The base station of claim 1 , wherein the at least one processor is configured to cause the base station to receive one or more of the first configuration or the second configuration from one or more of a different base station or a network function.
10 . A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive a first configuration for calculating one or more low-power radio monitoring occasions and a second configuration for calculating one or more main radio monitoring occasions; and
control a low-power radio and a main radio based at least in part on the first configuration and the second configuration.
11 . The UE of claim 10 , wherein to control the low-power radio and the main radio, the at least one processor is configured to cause the UE to:
determine, based at least in part on the first configuration, whether the UE is paged on a low-power radio monitoring occasion; and
control the main radio based at least in part on whether the UE is paged on the low-power radio monitoring occasion.
12 . The UE of claim 11 , wherein to control the low-power radio and the main radio, the at least one processor is configured to cause the UE to:
determine that paging is received on the low-power radio monitoring occasion and that the UE is paged; and
wake the main radio.
13 . The UE of claim 11 , wherein to control the low-power radio and the main radio, the at least one processor is configured to cause the UE to:
determine that paging is not received on the low-power radio monitoring occasion; and
wake the main radio on a main radio monitoring occasion.
14 . The UE of claim 11 , wherein to control the low-power radio and the main radio, the at least one processor is configured to cause the UE to:
determine that paging is received on the low-power radio monitoring occasion and that the UE is paged;
determine that the paging is not directed to the UE; and
maintain the main radio in a sleep mode.
15 . The UE of claim 11 , wherein to control the low-power radio and the main radio, the at least one processor is configured to cause the UE to:
wake the main radio based at least in part on whether the UE is paged on a low-power radio monitoring occasion; and
notify the main radio of a reason for waking the main radio.
16 . The UE of claim 10 , wherein the at least one processor is configured to cause the UE to receive one or more of the first configuration or the second configuration via system information broadcast from a base station.
17 . A processor for wireless communication, comprising:
at least one controller coupled with at least one memory and configured to cause the processor to:
receive a first configuration for calculating one or more low-power radio monitoring occasions and a second configuration for calculating one or more main radio monitoring occasions; and
control a low-power radio and a main radio based at least in part on the first configuration and the second configuration.
18 . The processor of claim 17 , wherein to control the low-power radio and the main radio, the at least one controller is configured to cause the processor to:
determine, based at least in part on the first configuration, whether a user equipment (UE) is paged on a low-power radio monitoring occasion; and
control the main radio based at least in part on whether the UE is paged on the low-power radio monitoring occasion.
19 . The processor of claim 18 , wherein to control the low-power radio and the main radio, the at least one controller is configured to cause the processor to:
determine that paging is received on the low-power radio monitoring occasion and that the UE is paged; and
wake the main radio.
20 . A method performed by a user equipment (UE), the method comprising:
receiving a first configuration for calculating one or more low-power radio monitoring occasions and a second configuration for calculating one or more main radio monitoring occasions; and
controlling a low-power radio and a main radio based at least in part on the first configuration and the second configuration.
