Abstract
Various arrangements for using multiple air interfaces on a frequency channel for side-link communications are presented. A first indication of a first time-window of a first resource pool may be transmitted by a first air interface system. A second indication of a second time-window of a second resource pool may be transmitted by a second air interface system. Side-link communications may be performed using the first air interface during only the first time-window of the first resource pool. Side-link communications may be performed using the second air interface during only the second time-window of the second resource pool.
Claims20
A method for accommodating multiple air interfaces for side-link communications, the method comprising:
- determining an allocation of a system resource pool among multiple different air interfaces such that a first air interface is assigned a first time-window of a frequency channel of the system resource pool, wherein:
- a second air interface has a second time-window of the frequency channel of the system resource pool;
- the first time-window and the second time-window do not overlap;
- and
- the system resource pool periodically repeats;
- providing a first indication of the first time-window of the system resource pool to a first air interface system, wherein:
- the first air interface system is in communication with a first cellular network that uses the first air interface;
- and
- transmitting, by the first air interface system, the first indication of the first time-window of the system resource pool to a first set of user equipment using the first air interface via the first cellular network, wherein:
- the first set of user equipment perform side-link communications using the first air interface during only the first time-window of the system resource pool.
A system that accommodating multiple air interfaces for side-link communications, the system comprising:
- an air interface coordination management server system that determines an allocation of a system resource pool among multiple different air interfaces such that a first air interface is assigned a first resource pool having a first time-window of the frequency channel, wherein:
- a second air interface has a second resource pool having a second time-window of the frequency channel;
- the first time-window and the second time-window do not overlap;
- and
- the system resource pool periodically repeats;
- and
- a first air interface system that receives an indication of the first time-window from the air interface coordination management server system and transmits, via a first cellular network, the indication of the first time-window to a first plurality of user equipment that communicate using the first air interface, wherein:
- the first plurality of user equipment that perform side-link communications using the first air interface during only the first time-window of the first resource pool.
A vehicle system that accommodates multiple air interfaces for side-link communications, the vehicle system comprising:
- a first air interface component that performs side-link communications using a first air interface;
- a second air interface component that performs side-link communications using a second air interface;
- a vehicle systems interface;
- and
- one or more processors, configured to:
- receive a resource pool allocation message via the first air interface component, wherein:
- the resource pool allocation message allocates a system resource pool among multiple different air interfaces such that the first air interface is assigned a first resource pool having a first time-window of a frequency channel, wherein:
- the second air interface has a second resource pool having second time-window of the frequency channel;
- the first time-window and the second time-window do not overlap;
- and
- the system resource pool periodically repeats;
- schedule a first side-link communication using the first air interface component and the first air interface during the first time-window on the frequency channel;
- and
- perform the first side-link communication during the first time-window on the frequency channel, wherein the first side-link communication uses data obtained from the vehicle systems interface.
