- Appl. No: 17/854740
- Application Filed: June 30, 2022
- Assignees: LG ELECTRONICS INC. (Seoul, KR)
- Claim: 1. A method of performing wireless communication by a first device, the method comprising: receiving downlink control information (DCI) related to first sidelink from a base station, wherein a sidelink configured grant is configured to the first device, and the sidelink configured grant is activated by the DCI; and transmitting, to the base station, a confirmation message through a first medium access control (MAC) control element (CE) including one or more fields, wherein a first field corresponding to a first configured grant with a first configured grant index, included in the one or more fields indicates confirmation to activation or deactivation of the first configured grant, and wherein the first field is ignored when the first configured grant is not configured to the first device.
- Claim: 2. The method of claim 1 , wherein the sidelink configured grant is configured the first device by RRC (radio resource control) signaling.
- Claim: 3. The method of claim 1 , wherein activation of the first configured grant is indicated based on the first field having a first value, and deactivation of the first configured grant is indicated based on the first field having a second value.
- Claim: 4. The method of claim 1 , wherein the first MAC CE is indicated by a MAC subheader with a logical channel ID (LCID).
- Claim: 5. The method of claim 1 , wherein the first MAC CE consists of one octet (octet).
- Claim: 6. The method of claim 1 , wherein the first MAC CE includes time information for the DCI related to the first sidelink.
- Claim: 7. The method of claim 6 , wherein the time information for the DCI related to the first sidelink includes information related to a start time for a system frame number (SFN) period within a period of the SFN and a time when the DCI related to the first sidelink is received from the base station.
- Claim: 8. The method of claim 6 , wherein the time information for the DCI related to the first sidelink includes information related to a time when the first MAC CE is transmitted to the base station through a physical uplink shared channel (PUSCH) and a time when the DCI related to the first sidelink is received from the base station.
- Claim: 9. The method of claim 1 , wherein a time when the first device applies the one or more configured grants after receiving the DCI related to the sidelink is determined based on the DCI related to the first sidelink.
- Claim: 10. The method of claim 1 , further comprising determining whether the base station has received the confirmation message, wherein, based on the base station receiving the confirmation message, sidelink communication is performed based on at least one SPS configuration.
- Claim: 11. The method of claim 1 , wherein the first MAC CE includes at least one of application ID information, destination ID information, target device ID information, session ID information, cast type information, service type information, priority information, information related to quality of service (QoS) or process ID information related to the first sidelink.
- Claim: 12. The method of claim 1 , further comprising: receiving DCI related to Uu communication from the base station; and transmitting, to the base station, a confirmation message for reception of DCI related to the Uu communication through a second MAC CE.
- Claim: 13. The method of claim 12 , wherein the first MAC CE and the second MAC CE include information for identifying the DCI related to the first sidelink and the DCI related to the Uu communication.
- Claim: 14. The method of claim 1 , further comprising receiving DCI related to a second sidelink from the base station, wherein, based on the confirmation message for reception of the DCI related to the second sidelink not transmitted to the base station, the confirmation message for reception of the DCI related to the second sidelink is included in the first MAC CE.
- Claim: 15. The method of claim 1 , wherein the first MAC CE is transmitted to the base station through a physical uplink shared channel (PUSCH).
- Claim: 16. The method of claim 1 , wherein resource on a physical sidelink shared channel (PSSCH) related to the first sidelink is scheduled by the base station.
- Claim: 17. The method of claim 1 , further comprising: performing a transmission related to the first sidelink to a second device based on the base station receiving the confirmation message, wherein the transmission related to the first sidelink is performed based on the DCI related to the first sidelink.
- Claim: 18. A first device configured for performing wireless communication, the first device comprising: one or more memories configured to store commands; one or more transceivers; and one or more processors functionally connecting the one or more memories and the one or more transceivers, wherein the one or more processors are configured to: receive downlink control information (DCI) related to first sidelink from a base station, wherein a sidelink configured grant is configured to the first device, and the sidelink configured grant is activated by the DCI; and transmit, to the base station, a confirmation message through a first medium access control (MAC) control element (CE) including one or more fields, wherein a first field corresponding a first configured grant with a first configured grant index, included in the one or more fields indicates confirmation to activation or deactivation of the first configured grant, and wherein the first field is ignored when the first configured grant is not configured to the first device.
