SYSTEM INFORMATION DESIGN FOR NEW RADIO (NR) VEHICLE-TO-EVERYTHING (V2X) SIDELINK OPERATION
This disclosure relates to embodiments New Radio (NR) vehicle-to-everything (V2X) communication. Some of embodiments generate system information block (SIB) messages having configurations for V2X communication modes, and transmit the SIB messages to a user equipment (UE). V2X communication modes include unicast, groupcast and broadcast modes. An example configuration includes a sidelink communication using a V2X communication mode.
1 . A user equipment (UE), comprising:
radio front end circuitry configured to receive a plurality of system information block (SIB) messages having a plurality of configurations for a plurality of vehicle-to-everything (V2X) communication modes from an access node (AN); and
processing circuitry configured to acquire a first configuration for a first communication mode from a first SIB message and a second configuration for a second communication mode from a second SIB message, wherein the second SIB message includes a delta that is associated with a common resource between the first configuration and the second configuration.
2 . The UE of claim 1 , wherein the first communication mode or the second communication mode comprises:
a unicast mode; or
a broadcast mode.
3 . The UE of claim 1 , wherein the first configuration or the second configuration comprises a sidelink communication using a broadcast operation.
4 . The UE of claim 1 , wherein the first configuration or the second configuration comprises a sidelink communication using a unicast operation.
5 . The UE of claim 1 , wherein the UE comprises a vehicular UE or a portion thereof.
6 . The UE of claim 1 , wherein the delta configuration comprises different congestion-to-priority mapping rules for the common resource.
7 . The UE of claim 1 , wherein the common resource comprises a carrier frequency that is applicable to the first communication mode and the second communication mode.
8 . A method for vehicle-to-everything (V2X) communication, the method comprising:
receiving, by a user equipment (UE), a plurality of system information block (SIB) messages having a plurality of configurations for a plurality of V2X communication modes from an access node (AN); and
acquiring, by the UE, a first configuration for a first communication mode from a first SIB message and a second configuration for a second communication mode from a second SIB message, wherein the second SIB message includes a delta that is associated with a common resource between the first configuration and the second configuration.
9 . The method of claim 8 , wherein the first communication mode or the second communication mode comprises:
a unicast mode; or
a broadcast mode.
10 . The method of claim 8 , wherein the first configuration comprises a sidelink communication using a broadcast operation.
11 . The method of claim 8 , wherein the second configuration comprises a sidelink communication using a unicast operation.
12 . The method of claim 8 , wherein the method is implemented by a vehicular UE or a portion thereof.
13 . The method of claim 8 , wherein the delta configuration comprises different congestion-to-priority mapping rules for the common resource.
14 . The method of claim 8 , wherein the common resource comprises a carrier frequency that is applicable to the first communication mode and the second communication mode.
15 . An apparatus comprising:
a memory; and
a processor configured to:
receive a plurality of system information block (SIB) messages having a plurality of configurations for a plurality of vehicle-to-everything (V2X) communication modes from an access node (AN), and
acquire a first configuration for a first communication mode from a first SIB message and a second configuration for a second communication mode from a second SIB message, wherein the second SIB message includes a delta that is associated with a common resource between the first configuration and the second configuration.
16 . The apparatus of claim 15 , wherein the first communication mode or the second communication mode comprises:
a unicast mode; or
a broadcast mode.
17 . The apparatus of claim 15 , wherein the first configuration comprises a sidelink communication using a broadcast operation.
18 . The apparatus of claim 15 , wherein the second configuration comprises a sidelink communication using a unicast operation.
19 . The apparatus of claim 15 , wherein the delta configuration comprises different congestion-to-priority mapping rules for the common resource.
20 . The apparatus of claim 15 , wherein the common resource comprises a carrier frequency that is applicable to the first communication mode and the second communication mode.
