Abstract

Provided are a method and apparatus for resource configuration for a sidelink in Internet of vehicles. The method includes: a terminal receiving configuration information about a sidelink Bandwidth part (BWP)/resource pool; and the terminal performing sidelink data transmission according to the received configuration information about the sidelink BWP/resource pool.

First claim

What is claimed is:

1. A method for resource configuration for a sidelink communication in Internet of vehicles, comprising:
transmitting, by a terminal, request information to a base station, the request information comprising: 5G quality of service indication (5QI), quality of service flow identity (QFI), packet delay budget (PDB), priority, packet error rate (PER), and guaranteed flow bit rate (GFBR);
receiving, by the terminal, configuration information about a sidelink bandwidth part (BWP);
performing, by the terminal, sidelink data transmission according to the received configuration information about the sidelink BWP;
transmitting, by the terminal, a scheduling request (SR) for requesting a sidelink resource; and
before transmitting, by the terminal, the SR for requesting the sidelink resource, receiving, by the terminal, SR configuration which is transmitted by the base station and dedicated to requesting the sidelink communication.

2. The method of claim 1 , wherein the configuration information about the sidelink BWP comprises at least one of: a BWP index, a BWP bandwidth, a BWP position, a subcarrier spacing, or a cyclic prefix.

3. The method of claim 1 , wherein the request information further comprises:
a sidelink unicast communication destination identity (ID), a sidelink broadcast communication destination ID, or a sidelink groupcast communication destination ID.

4. The method of claim 1 , wherein the request information further comprises:
a resource configuration request for sidelink broadcast communication or a resource configuration request for sidelink groupcast communication.

5. The method of claim 1 , wherein the sidelink BWP further comprises:
an initial sidelink BWP; wherein the initial sidelink BWP is configured for at least one of: establishing a sidelink unicast connection, or transmitting or receiving signaling for unicast data transmission resource configuration over a corresponding sidelink BWP.

6. The method of claim 5 , wherein the unicast data transmission resource configuration comprises:
transmitting, by a first terminal to a second terminal, an available sidelink BWP carrying vehicle to everything (V2X) traffic information; and
receiving, by the first terminal, at least one of the following information transmitted by the second terminal: acceptable V2X service information, configuration of a supported sidelink BWP for transmission, or configuration of a supported sidelink BWP for reception.

7. The method of claim 1 , further comprising at least one of:
for an unpaired spectrum, multiplexing a same Uu BWP for the sidelink BWP, paging and SI;
for a scenario where a Uu uplink (UL) resource is used for the sidelink communication, configuring a same sidelink BWP and a UL BWP, or configuring the sidelink BWP and the UL BWP to be superposed in frequency domain; or

for a scenario where a dedicated PC5 carrier is used for the sidelink communication, configuring the sidelink BWP and the Uu BWP independently.

8. The method of claim 1 , further comprising receiving, by the terminal, configuration information about a sidelink resource pool; and
wherein the configuration information about the sidelink resource pool comprises configuration information about a sidelink transmission and/or reception resource pool corresponding to at least one of LTE or new radio (NR).

9. The method of claim 8 , further comprising performing, by the terminal, the sidelink data transmission according to the received configuration information about the sidelink resource pool.

10. The method of claim 1 , further comprising:
receiving, by the terminal, at least one of sidelink bearer channel configuration information or sidelink logical channel configuration information transmitted by the base station.

11. The method of claim 1 , further comprising:
receiving, by the terminal, sidelink grant downlink control information (DCI) transmitted by the base station, wherein the sidelink grant DCI comprises an index of the sidelink BWP.

12. An electronic apparatus, comprising a memory and a processor, wherein the memory is configured to store a computer program, and the processor is configured to execute the computer program to perform steps comprising:
transmitting, by a terminal, request information to a base station, the request information comprising: 5G quality of service indication (5QI), quality of service flow identity (QFI), packet delay budget (PDB), priority, packet error rate (PER), and guaranteed flow bit rate (GFBR);
receiving, by the terminal, configuration information about a sidelink bandwidth part (BWP);
performing, by the terminal, sidelink data transmission according to the received configuration information about the sidelink BWP;

transmitting, by the terminal, a scheduling request (SR) for requesting a sidelink resource; and
before transmitting, by the terminal, the SR for requesting the sidelink resource, receiving, by the terminal, SR configuration which is transmitted by the base station and

dedicated to requesting a sidelink communication.
