Resource selection for vehicle (V2X) communications
View Patent ↗Method and apparatus comprise selecting radio resources for vehicle (V2X) communication for use by a wireless terminal, and particular making such selection using selection/allocation criteria such as geographical area, direction of vehicle travel and/or density of wireless communications in an area pertinent to a wireless terminal.
1. A wireless terminal comprising:
memory circuitry configured to store information specifying multiple resource pools, wherein each of the multiple resource pools has its own first index;
determination circuitry configured to determine a second index of a current geographical region; and,
selection controlling circuitry configured to select a resource pool from the multiple resource pools;
wherein the selected resource pool is a resource pool having the first index equal to the determined second index.
2. The wireless terminal of claim 1 , wherein
the information is pre-configured in the memory circuitry.
3. The wireless terminal of claim 1 , wherein
the wireless terminal further comprises controlling circuitry configured to receive a system information block (SIB) which carries the information.
4. The wireless terminal of claim 1 , wherein the wireless terminal further comprises transmission circuitry configured to transmit a sidelink communication transmission using the selected resource pool.
5. A method in a wireless terminal comprising:
obtaining information specifying multiple resource pools, wherein each of the multiple resource pools has its own first index;
determining a second index of a current geographical region; and
selecting a resource pool from the multiple resource pools, wherein the selected resource pool is a resource pool having the first-index equal to the determined second index.
6. The method of claim 5 , wherein
the information is obtained from memory circuitry in the wireless terminal.
7. The method of claim 5 , wherein
the method further comprises receiving a system information block (SIB) which carries the information.
8. The method of claim 5 , wherein the method further comprises transmitting a sidelink communication transmission using the selected resource pool.
