## Abstract

A method for physical layer monitoring and related apparatuses are provided in implementations of the disclosure, where the method and the related apparatuses are applied to a user equipment (UE). The method includes: determining a monitor mode for a type-1 physical downlink control channel (PDCCH) according to a type-1 wakeup indication; or determining the monitor mode for the type-1 PDCCH according to a type-2 wakeup indication; or determining the monitor mode for the type-1 PDCCH according to a type-1 PDCCH skipping indication; or determining the monitor mode for the type-1 PDCCH according to a type-2 PDCCH skipping indication.

## Claims

### Claim 1

A method for physical layer monitoring, applied to a user equipment (UE) and comprising:
determining a monitor mode for a type-1 physical downlink control channel (PDCCH) according to a type-1 wakeup indication; and
performing monitoring on the type-1 PDCCH,
wherein determining the monitor mode for the type-1 PDCCH according to the type-1 wakeup indication comprises:
determining a value of the type-1 wakeup indication, wherein the type-1 wakeup indication comprises one bit; and
if the value of the type-1 wakeup indication is a value A and a higher-layer parameter is a higher-layer parameter value A, determining that the monitor mode for the type-1 PDCCH is to monitor the type-1 PDCCH; or
if the value of the type-1 wakeup indication is the value A and the higher-layer parameter is a higher-layer parameter value B, determining that the monitor mode for the type-1 PDCCH is not to monitor the type-1 PDCCH.

### Claim 2 (depends on 1)

The method of claim 1, wherein determining the monitor mode for the type-1 PDCCH according to the type-1 wakeup indication further comprises:
if the value of the type-1 wakeup indication is the value A and a value of a logical channel priority is greater than or equal to a threshold A, determining that the monitor mode for the type-1 PDCCH is to monitor the type-1 PDCCH; or
if the value of the type-1 wakeup indication is the value A and the value of the logical channel priority is less than the threshold A, determining that the monitor mode for the type-1 PDCCH is not to monitor the type-1 PDCCH.

### Claim 3 (depends on 1)

The method of claim 1, wherein the type-1 PDCCH is a PDCCH for a heartbeat traffic.

### Claim 4

A user equipment (UE), comprising a processor, a memory, a communication interface, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processor, and the one or more programs comprise instructions configured to perform:
if a value of a type-1 wakeup indication is a value A and a value of a logical channel priority is greater than or equal to a threshold A, determining that a monitor mode for a type-1 physical downlink control channel (PDCCH) is to monitor the type-1 PDCCH; or if the value of the type-1 wakeup indication is the value A and the value of the logical channel priority is less than the threshold A, determining that the monitor mode for the type-1 PDCCH is not to monitor the type-1 PDCCH; and
performing monitoring on the type-1 PDCCH.

### Claim 5 (depends on 4)

The UE of claim 4, wherein the type-1 PDCCH is a PDCCH for a heartbeat traffic.

### Claim 6

A user equipment (UE), comprising a processor, a memory, a communication interface, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the processor, and the one or more programs comprise instructions configured to perform:
determining a value of a type-2 wakeup indication, wherein the type-2 wakeup indication comprises two bits;
determining a monitor mode for a type-1 physical downlink control channel (PDCCH) according to the value of the type-2 wakeup indication; and
performing monitoring on the type-1 PDCCH,
wherein determining the monitor mode for the type-1 PDCCH according to the value of the type-2 wakeup indication comprises:
when the value of the type-2 wakeup indication is a value E, determining that the monitor mode for the type-1 PDCCH is to stop a timer, monitor the type-1 PDCCH, and start an inactivity timer corresponding to the type-1 PDCCH, wherein the inactivity timer corresponding to the type-1 PDCCH is different from an inactivity timer corresponding to each of other PDCCHs except the type-1 PDCCH.

### Claim 7 (depends on 6)

The UE of claim 6, wherein in terms of determining the monitor mode for the type-1 PDCCH according to the value of the type-2 wakeup indication, the one or more programs further comprise instructions configured to perform:
if the value of the type-2 wakeup indication is a value B, determining that the monitor mode for the type-1 PDCCH is to stop a timer and not to monitor the type-1 PDCCH.

### Claim 8 (depends on 6)

The UE of claim 6, wherein in terms of determining the monitor mode for the type-1 PDCCH according to the value of the type-2 wakeup indication, the one or more programs further comprise instructions configured to perform:
if the value of the type-2 wakeup indication is a value C, determining that the monitor mode for the type-1 PDCCH is to stop a timer and monitor the type-1 PDCCH.

### Claim 9 (depends on 6)

The UE of claim 6, wherein in terms of determining the monitor mode for the type-1 PDCCH according to the value of the type-2 wakeup indication, the one or more programs further comprise instructions configured to perform:
if the value of the type-2 wakeup indication is a value D, determining that the monitor mode for the type-1 PDCCH is to start a timer and monitor the type-1 PDCCH.

### Claim 10 (depends on 6)

The UE of claim 6, wherein the type-1 PDCCH is a PDCCH for a heartbeat traffic.
