## Abstract

An example of the present disclosure provides a wakeup method, including: determining user equipment (UE) to be waked up; and sending indication information to the user equipment, wherein the indication information is used to indicate a beam and a time domain resource and/or a frequency domain resource for receiving a wakeup signal block by the UE.

## Claims

### Claim 1

A wakeup method applied to a base station, comprising:
determining user equipment to be waked up, wherein the user equipment is in one of an idle state or a connected state; and
sending indication information to the user equipment, wherein the indication information is configured to indicate a beam and at least one of a time domain resource or a frequency domain resource, for receiving a wakeup signal block by the user equipment,
wherein the indication information is one of system information for the user equipment in the idle state or a radio resource control message for the user equipment in the connected state;
when the indication information is the system information for the user equipment in the idle state, the indication information indicates the beam for receiving the wakeup signal block by the user equipment through an index of a synchronization signal block; and
when the indication information is the radio resource control message for the user equipment in the connected state, the indication information indicates the beam for receiving the wakeup signal block by the user equipment through at least one of:
an index of a synchronization signal block; or
a channel state information reference signal.

### Claim 2 (depends on 1)

The wakeup method according to claim 1, wherein the indication information is the system information for the user equipment in the idle state, and the system information is sent to the user equipment by broadcasting or on demand.

### Claim 3 (depends on 1)

The wakeup method according to claim 1, wherein the indication information is further configured to indicate a structure of the wakeup signal block.

### Claim 4 (depends on 3)

The wakeup method according to claim 3, wherein the structure of the wakeup signal block comprises one of:
a wakeup signal;
a physical channel; and
a wakeup signal and a physical channel.

### Claim 5 (depends on 1)

The wakeup method according to claim 1, wherein the indication information is further configured to indicate a state of the beam when the user equipment is receiving the wakeup signal block.

### Claim 6

A wakeup method applied to user equipment, comprising:
receiving indication information sent from a base station, wherein the user equipment is in one of an idle state or a connected state; and
determining a beam and at least one of a time domain resource or a frequency domain resource, for receiving a wakeup signal block according to the indication information,
wherein the indication information is one of system information for the user equipment in the idle state or a radio resource control message for the user equipment in the connected state;
when the indication information is the system information for the user equipment in the idle state, the indication information indicates the beam for receiving the wakeup signal block by the user equipment through an index of a synchronization signal block; and
when the indication information is the radio resource control message for the user equipment in the connected state, the indication information indicates the beam for receiving the wakeup signal block by the user equipment through at least one of:
an index of a synchronization signal block; or
a channel state information reference signal.

### Claim 7 (depends on 6)

The wakeup method according to claim 6, wherein the user equipment is in the idle state, and receiving the indication information sent from the base station comprises:
receiving the system information by monitoring or on demand.

### Claim 8 (depends on 6)

The wakeup method according to claim 6, further comprising:
determining a structure of the wakeup signal block according to the indication information.

### Claim 9 (depends on 8)

The wakeup method according to claim 8, wherein the structure of the wakeup signal block comprises one of:
a wakeup signal;
a physical channel; and
a wakeup signal and a physical channel.

### Claim 10 (depends on 6)

The wakeup method according to claim 6, further comprising:
determining a state of the beam when the user equipment is receiving the wakeup signal block according to the indication information.

### Claim 11 (depends on 1)

A base station, comprising:
a processor; and
a memory storing instructions executable by the processor,
wherein the processor is configured to perform the method according to claim 1.

### Claim 12

An electronic device, comprising:
a processor; and
a memory storing instructions executable by the processor,
wherein the processor is configured to:
receive indication information sent from a base station, wherein the electronic device is in an idle state or a connected state; and
determine a beam and at least one of a time domain resource or a frequency domain resource, for receiving a wakeup signal block according to the indication information,
wherein the indication information is one of system information for the electronic device in the idle state or a radio resource control message for the electronic device in the connected state;
when the indication information is the system information for the user equipment in the idle state, the indication information indicates the beam for receiving the wakeup signal block by the user equipment through an index of a synchronization signal block; and
when the indication information is the radio resource control message for the user equipment in the connected state, the indication information indicates the beam for receiving the wakeup signal block by the user equipment through at least one of:
an index of a synchronization signal block; or
a channel state information reference signal.
