Configuring sidelink communications
View Patent ↗Systems and methods to configure sidelink resources in a dual connectivity operation are provided. In some aspect, a method comprising: transmitting, from a user equipment (UE), a first message to a first evolved Node B (eNB), wherein the first message indicates a request to establish a sidelink communication; receiving, at the UE, a second message from the first eNB, wherein the second message indicates a frequency that is used by a secondary evolved Node B (SeNB); transmitting, from the UE, a measurement result to the first eNB; and receiving, at the UE, sidelink configuration information from the first eNB, wherein the sidelink configuration information indicates sidelink resources managed by the secondary eNB.
1. A method, comprising:
transmitting, from a user equipment (UE), a first message to a first Base Station (BS), wherein the first message indicates a request to establish a sidelink communication;
receiving, at the UE, a second message from the first BS, wherein the second message indicates a frequency that is used by a second BS;
transmitting, from the UE, a measurement result to the first BS; and
receiving, at the UE, sidelink configuration information from the first BS, wherein the sidelink configuration information indicates sidelink resources managed by the second BS, and the sidelink configuration information indicates that the first BS provides scheduling for the sidelink communication.
2. The method of claim 1 , wherein the sidelink communication is a V2X sidelink communication.
3. The method of claim 2 , wherein the UE operates in a dual connectivity (DC) mode with both the first BS and the second BS.
4. The method of claim 1 , further comprising: transmitting, in the first message from the UE, a capability indicator to the first BS, wherein the capability indicator indicates that the UE supports V2X sidelink communications via Dual Connectivity configuration.
5. The method of claim 1 , further comprising: performing the sidelink communication using the sidelink resources.
6. The method of claim 1 , wherein the sidelink configuration information indicates whether the first BS or the second BS provides synchronization for the sidelink communication.
7. A user equipment (UE), comprising:
at least one hardware processor; and
a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions, when executed, cause the at least one hardware processor to perform operations comprising:
transmitting, from the UE, a first message to a first Base Station (BS), wherein the first message indicates a request to establish a sidelink communication;
receiving, at the UE, a second message from the first BS, wherein the second message indicates a frequency that is used by a second BS;
transmitting, from the UE, a measurement result to the first BS; and
receiving, at the UE, sidelink configuration information from the first BS, wherein the sidelink configuration information indicates sidelink resources managed by the second BS, and the sidelink configuration information indicates that the first BS provides scheduling for the sidelink communication.
8. The UE of claim 7 , wherein the sidelink communication is a V2X sidelink communication.
9. The UE of claim 8 , wherein the UE operates in a dual connectivity (DC) mode with both the first BS and the second BS.
10. The UE of claim 7 , the operations further comprising: transmitting, in the first message from the UE, a capability indicator to the first BS, wherein the capability indicator indicates that the UE supports V2X sidelink communications via Dual Connectivity configuration.
11. The UE of claim 7 , the operations further comprising: performing the sidelink communication using the sidelink resources.
12. The UE of claim 7 , wherein the sidelink configuration information indicates whether the first BS or the second BS provides synchronization for the sidelink communication.
13. A non-transitory computer-readable medium storing instructions which, when executed, cause a computing device to perform operations comprising:
transmitting, from a user equipment (UE), a first message to a first Base Station (BS), wherein the first message indicates a request to establish a sidelink communication;
receiving, at the UE, a second message from the first BS, wherein the second message indicates a frequency that is used by a second BS;
transmitting, from the UE, a measurement result to the first BS; and
receiving, at the UE, sidelink configuration information from the first BS, wherein the sidelink configuration information indicates sidelink resources managed by the second BS, and the sidelink configuration information indicates that the first BS provides scheduling for the sidelink communication.
14. The non-transitory computer-readable medium of claim 13 , wherein the sidelink communication is a V2X sidelink communication.
15. The non-transitory computer-readable medium of claim 14 , wherein the UE operates in a dual connectivity (DC) mode with both the first BS and the second BS.
16. The non-transitory computer-readable medium of claim 13 , the operations further comprising: transmitting, in the first message from the UE, a capability indicator to the first BS, wherein the capability indicator indicates that the UE supports V2X sidelink communications via Dual Connectivity configuration.
17. The non-transitory computer-readable medium of claim 13 , the operations further comprising: performing the sidelink communication using the sidelink resources.
18. The non-transitory computer-readable medium of claim 13 , wherein the sidelink configuration information indicates whether the first BS or the second BS provides synchronization for the sidelink communication.
