Intra- and inter-RAT co-existence and congestion control for LTE PC5-based vehicle-to-vehicle (V2V) communication

A user equipment device (UE), comprising:

• Radio Frequency (RF) circuitry;
• and
• baseband circuitry in communication with the RF circuitry and configured to cause the UE to perform operations, the operations comprising:
• receiving, from a base station, an indication of at least one sub-channel and resource pool for the UE to use for communication with other UEs and not for transmissions to the base station, wherein the resource pool is disposed in a physical sidelink channel;
• and
• receiving, from the base station, an indication of at least one metric for measurement of D2D transmissions, on the at least one sub-channel and the resource pool, for adjustment of at least one transmission parameter.
