## Abstract

A method for scheduling request (SR) transmission is provided. The method may include the following steps. A first user equipment (UE) may transmit an indication for data transmission to a second UE. The second UE may transmit an SR to a network node based on the indication before receiving data from the first UE.

## Claims

### Claim 1

A method for scheduling request (SR) transmission, comprising:
transmitting, by a first user equipment (UE), an indication for data transmission to a second UE; and
transmitting, by the second UE, an SR to a network node based on the indication before receiving data from the first UE,
wherein the method further comprises:
transmitting, by the network node, an uplink (UL) grant for the SR to the second UE; and
transmitting, by the second UE, a buffer status report (BSR) to the network node in response to the second UE not receiving the data from the first UE.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
receiving, by the second UE, the data from the first UE after the second UE transmits the SR to the network node;
transmitting, by the network node, an uplink (UL) grant for the SR to the second UE; and
transmitting, by the second UE, the data to the network node.

### Claim 3 (depends on 1)

The method of claim 1, wherein the transmitting of the indication further comprises:
transmitting, by the first UE, the indication to the second UE through a Wi-Fi, a bluetooth (BT), sidelink or a cable.

### Claim 4 (depends on 1)

The method of claim 1, wherein the indication comprises at least one of traffic profile and quality of service (QoS) information.

### Claim 5 (depends on 1)

The method of claim 1, wherein the first UE is an augmented reality (AR) glasses.

### Claim 6

A system for scheduling request (SR) transmission, comprising:
a first user equipment (UE);
a second UE, communicating with the first UE via a communication link; and
a network node, wirelessly communicating with the second UE,
wherein the first UE transmits an indication for data transmission to the second UE; and
wherein the second UE transmits an SR to a network node based on the indication before receiving data from the first UE,
wherein the network node transmits an uplink (UL) grant for the SR to the second UE, and the second UE transmits a buffer status report (BSR) to the network node in response to the second UE not receiving the data from the first UE.

### Claim 7 (depends on 6)

The system of claim 6, wherein the second UE receives the data from the first UE after the second UE transmits the SR to the network node, the network node transmits an uplink (UL) grant for the SR to the second UE, and the second UE transmits data to the network node.

### Claim 8 (depends on 6)

The system of claim 6, wherein the communication link comprises a Wi-Fi, a bluetooth (BT), sidelink and a cable.

### Claim 9 (depends on 6)

The system of claim 6, wherein the indication comprises at least one of traffic profile and quality of service (QoS) information.

### Claim 10 (depends on 6)

The system of claim 6, wherein the first UE is an augmented reality (AR) glasses.

### Claim 11

A method for scheduling request (SR) transmission, comprising:
receiving, by a transceiver of a user equipment (UE), an indication for data transmission from another UE; and
transmitting, by the transceiver, an SR to a network node based on the indication before receiving data from the another UE,
wherein the method further comprises:
receiving, by the transceiver, an uplink (UL) grant for the SR from the network node; and
transmitting, by the transceiver, a buffer status report (BSR) to the network node in response to the second UE not receiving the data from the first UE.

### Claim 12 (depends on 11)

The method of claim 11, further comprising:
receiving, by the transceiver, the data from the another UE after transmitting the SR to the network node;
receiving, by the transceiver, an uplink (UL) grant for the SR from the network node; and
transmitting, by the transceiver, the data to the network node.

### Claim 13 (depends on 11)

The method of claim 11, wherein the indication comprises at least one of traffic profile and quality of service (QoS) information.

### Claim 14

A user equipment (UE) for scheduling request (SR) transmission, comprising:
a transceiver, receiving an indication for data transmission from another UE; and
a processor, coupled to the transceiver and determining to transmit, via the transceiver, an SR to a network node based on the indication before receiving data from the another UE,
wherein the transceiver receives an uplink (UL) grant for the SR from the network node, and the transceiver transmits a buffer status report (BSR) to the network node in response to the UE not receiving the data from the another UE.

### Claim 15 (depends on 14)

The UE of claim 14, wherein the transceiver receives the data from the another UE after transmitting the SR to the network node, the transceiver receives an uplink (UL) grant for the SR from the network node, and the transceiver transmits data to the network node.

### Claim 16 (depends on 14)

The UE of claim 14, wherein the indication comprises at least one of traffic profile and quality of service (QoS) information.
