## Abstract

Provided is a wireless communication method and related apparatus. In the method, a base station receives a capability of a repeater, and if a repeater gain of the repeater is allowed to be increased based on the capability of the repeater, the base station requires at least one user equipment to reduce transmit power and use the reduced transmit power to transmit uplink signals. With this method, the transmit power of the user equipment served by the repeater can be effectively reduced to get the benefit of saving UE's power consumption.

## Claims

### Claim 1

A wireless communication method, applied to a second device communicating with at least one third device via a first device, which is used to amplify cellular communication signals between the second device and the at least one third device in a network, the method comprising:
receiving a capability of the first device;
in response to determining, based on the capability of the first device, that a repeater gain of the first device is allowed to be increased, requiring the at least one third device to reduce transmit power and use the reduced transmit power to transmit uplink signals; and
notifying the first device to increase the repeater gain to amplify, with the increased repeater gain, the uplink signals transmitted by the at least one third device with the reduced transmit power.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the step of requiring the at least one third device to reduce the transmit power comprises:
requiring the at least one third device, which is a disconnected device but within a coverage serviced by the first device, to transmit random access data by a designated received power at the second device through open-loop power control.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the step of requiring the at least one third device to reduce the transmit power comprises:
requiring the at least one third device, which is a connected device and within a coverage serviced by the first device, to transmit the uplink signals by a designated transmit power through closed-loop power control.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the smaller the uplink signals received by the first device is, the greater the repeater gain is utilized.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the capability of the first device comprises at least one of a maximum Total Power Repeater Gain (TPRG), a maximum RBRG, and a maximum total transmit power.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the repeater gain is a resource block repeater gain (RBRG) for one or more resource blocks, and the one or more resource blocks allocated to the at least one third device served by the first device are amplified based on the RBRG; or
wherein the repeater gain is a Total Power Repeater Gain (TPRG) for the first device, and the uplink signals transmitted from the at least one third device are amplified based on the TPRG.

### Claim 7 (depends on 1)

The method according to claim 1, wherein resource blocks allocated to a same third device are amplified with different repeater gains.

### Claim 8 (depends on 1)

The method according to claim 1, wherein resource blocks allocated to different third devices are amplified with different repeater gains.

### Claim 9

A wireless communication method, applied to a third device communicating with a second device via a first device, which is used to amplify cellular communication signals between the second device and the third device in a network, the method comprising:
being notified of reducing transmit power in a case that a repeater gain of the first device is allowed to be increased; and
using the reduced transmit power to transmit uplink signals to the first device,
wherein the uplink signals transmitted by the third device with the reduced transmit power are amplified by the first device with an increased repeater gain.

### Claim 10 (depends on 9)

The method according to claim 9, wherein the step of being notified of reducing the transmit power comprises:
in response to the third device is a disconnected device but within a coverage serviced by the first device, being notified of transmitting random access data by a designated received power at the second device through open-loop power control.

### Claim 11 (depends on 9)

The method according to claim 9, wherein the step of being notified of reducing the transmit power comprises:
in response to the third device is a connected device within a coverage serviced by the first device, being notified of transmitting the uplink signals by a designated transmit power through closed-loop power control.

### Claim 12 (depends on 9)

The method according to claim 9, wherein the smaller the uplink signals received by the first device is, the greater the repeater gain is utilized.

### Claim 13 (depends on 9)

The method according to claim 9, wherein the repeater gain is a resource block repeater gain (RBRG) for one or more resource blocks, and the one or more resource blocks allocated to the third device served by the first device are amplified based on the RBRG; or
wherein the repeater gain is a Total Power Repeater Gain (TPRG) for the first device, and the uplink signals transmitted from the at least one third device are amplified based on the TPRG.

### Claim 14 (depends on 9)

The method according to claim 9, wherein resource blocks allocated to the third device are amplified with different repeater gains.
