Abstract

An example method includes generating, by a first user device, a first number representing a contention resolution priority for the first user device contending for at least one first resource over a first data period for transmitting a packet of data in a device-to-device (D2D) wireless network, determining if a second device, in the D2D wireless network, is contending for resources overlapping with the at least one first resource of the first data period, if the second device is contending for resources overlapping with the at least one first resource of the first data period, determining if a second number representing a contention resolution priority for the second user device is greater than the first number, and if the second number is greater than the first number, inhibiting the first user device from communicating using the at least one first resource of the first data period.

Claims16

Dependent claims

A method comprising:

generating, by a first user device, a first number representing a contention resolution priority for the first user device contending for at least one first resource over a first data period for transmitting a packet of data in a device-to-device (D2D) wireless network;
determining if a second user device, in the D2D wireless network, is contending for resources overlapping with the at least one first resource of the first data period, wherein the determining includes:
receiving a message over a control channel including a scheduling assignment (SA) during a SA period associated with the first data period, wherein the message includes a second number representing a contention resolution priority for the second user device;
if the second user device is contending for resources overlapping with the at least one first resource of the first data period, determining if the second number is greater than the first number;
and
if the second number is greater than the first number, inhibiting the first user device from communicating using the at least one first resource of the first data period.

3 more elements

A first user device comprising at least one processor and at least one memory including computer instructions, when executed by the at least one processor, cause the first user device to:

generate a first number representing a contention resolution priority for a first user device contending for at least one first resource over a first data period for transmitting a packet of data in a device-to-device (D2D) wireless network;
determine if a second user device, in the D2D wireless network, is contending for resources overlapping with the at least one first resource of the first data period, including causing the first user device to receive a message over a control channel including a scheduling assignment (SA) during a SA period associated with the first data period, wherein the message includes a second number representing a contention resolution priority for the second user device;
if the second user device is contending for resources overlapping with the at least one first resource of the first data period, determine if the second number is greater than the first number;
and
if the second number is greater than the first number, inhibiting the first user device from communicating using the at least one first resource of the first data period.
