Abstract
Some of the present implementations provide a method for a first user equipment (UE) to exchange sidelink packets with at least a second UE. The method receives, through a first interface and via a radio resource control (RRC) signaling, a sidelink configuration from a first base station during a handover procedure of the first UE to a second base station. The method then exchanges, through a second interface, one or more sidelink packets with the second UE based on the sidelink configuration received from the first base station and previously stored sidelink configuration at the first UE. The first interface is configurable to be one of a long term evolution (LTE) Uu interface and a new radio (NR) Uu interface, and the second interface is configurable to be one of an LTE proximity service (ProSe) sidelink PC5 interface and an NR ProSe sidelink PC5 interface.

Claim
1. A method for configuring a first user equipment (UE) to exchange sidelink packets with at least a second UE, the method comprising:
receiving, at the first UE, via a radio resource control (RRC) signaling, through a first interface, a sidelink configuration from a first base station during a handover procedure to a second base station; and exchanging, through a second interface, one or more sidelink packets with the second UE based on the sidelink configuration received from the first base station and previously stored sidelink configuration at the first UE, wherein the first interface is configurable to be one of a long term evolution (LTE) Uu interface and a new radio (NR) Uu interface, and the second interface is configurable to be one of an LTE proximity service (ProSe) sidelink PC5 interface and an NR ProSe sidelink PC5 interface.
2. The method of claim 1, wherein the sidelink configuration comprises one or more Type 1 sidelink configured grant configurations comprising at least one of a time periodicity and locations of physical resource blocks in time and frequency domains, wherein exchanging the one or more sidelink packets with the second UE comprises transmitting sidelink packets to the second UE using a configured Type 1 sidelink configured grant after receiving the sidelink configuration from the first base station successfully.
3. The method of claim 1, wherein the sidelink configuration comprises one or more Type 2 sidelink configured grant configurations comprising at least a time periodicity in a time domain.
4. The method of claim 1 further comprising:
receiving a downlink control information (DCI) message from the second base station to activate at least a configured Type 2 sidelink configured grant received in the sidelink configuration, wherein the DCI message comprises locations of physical resource blocks in time and frequency domains at the first interface, wherein exchanging the one or more sidelink packets with the second UE comprises transmitting sidelink packets to the second UE using the activated Type 2 sidelink configured grant.
5. The method of claim 1, wherein the sidelink configuration comprises one or more sidelink Transmission (Tx) resource pool configurations, wherein exchanging the one or more sidelink packets with the second UE comprises transmitting sidelink packets to the second UE using a configured sidelink Tx resource pool after the first UE handovers to the second base station successfully.
6. The method of claim 1 further comprising:
modifying at least part of the previously stored sidelink configuration at the first UE based on the sidelink configuration received from the first base station; and
storing the modified sidelink configuration at the first UE, as a most recently updated sidelink configuration.
7. The method of claim 1 further comprising:
exchanging, by the first UE, data and control signaling with the first base station and the second base station through different interfaces configured with different radio access technologies (RATs) comprising at least an LTE RAT and an NR RAT.
8. A first user equipment (UE) comprising:
one or more non-transitory computer-readable media having computer-executable instructions for exchange sidelink packets with at least a second UE; and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
receive, at the first UE, via a radio resource control (RRC) signaling, through a first interface, a sidelink configuration from a first base station during a handover procedure to a second base station; and
exchange, through a second interface, one or more sidelink packets with the second UE based on the sidelink configuration received from the first base station and previously stored sidelink configuration at the first UE, wherein
the first interface is configurable to be one of a long term evolution (LTE) Uu interface and a new radio (NR) Uu interface, and
the second interface is configurable to be one of an LTE proximity service (ProSe) sidelink PC5 interface and an NR ProSe sidelink PC5 interface.
9. The first UE of claim 8, wherein the sidelink configuration comprises one or more Type 1 sidelink configured grant configurations comprising at least one of a time periodicity and locations of physical resource blocks in time and frequency domains, wherein executing the computer-executable instructions to exchange the one or more sidelink packets with the second UE comprises executing the computer-executable instructions to transmit sidelink packets to the second UE using a configured Type 1 sidelink configured grant after receiving the sidelink configuration from the first base station successfully.
10. The first UE of claim 8, wherein the sidelink configuration comprises one or more Type 2 sidelink configured grant configurations comprising at least a time periodicity in a time domain.
11. The first UE of claim 8, wherein the at least one processor is further configured to execute the computer-executable instructions to:
receive a downlink control information (DCI) message from the second base station to activate at least a configured Type 2 sidelink configured grant received in the sidelink configuration, wherein the DCI message comprises locations of physical resource blocks in time and frequency domains at the first interface, wherein executing the computer-executable instructions to exchange the one or more sidelink packets with the second UE comprises executing the computer-executable instructions to transmit sidelink packets to the second UE using the activated Type 2 sidelink configured grant.
12. The first UE of claim 8, wherein the sidelink configuration comprises one or more sidelink Transmission (Tx) resource pool configurations, wherein executing the computer-executable instructions to exchange the one or more sidelink packets with the second UE comprises executing the computer-executable instructions to transmit sidelink packets to the second UE using a configured sidelink Tx resource pool after the first UE handovers to the second base station successfully.
13. The first UE of claim 8, wherein the at least one processor is further configured to execute the computer-executable instructions to:
modify at least part of the previously stored sidelink configuration at the first UE based on the sidelink configuration received from the first base station; and store the modified sidelink configuration at the first UE, as a most recently updated sidelink configuration.
14. The first UE of claim 8, wherein the at least one processor is further configured to execute the computer-executable instructions to:
exchange, by the first UE, data and control signaling with the first base station and the second base station through different interfaces configured with different radio access technologies (RATs) comprising at least an LTE RAT and an NR RAT.
15. A method for a first base station for configuring a first user equipment (UE) to exchange sidelink packets with at least a second UE, the method comprising:
