System and method for resource allocation for device-to-device communications

A wireless device for providing IP address translation services, the wireless device comprising:

• a memory storing instructions;
• and
• one or more processors in communication with the memory, the one or more processors operable to execute the instructions to cause the one or more processors to:
• receive signaling of a transmission schedule, the transmission schedule comprising:
• a first plurality of transmission opportunities allocated to a device-to-device link;
• and
• a second plurality of transmission opportunities allocated to a cellular link;
• and
• during a transmission opportunity within the first plurality of transmission opportunities or the second plurality of transmission opportunities, transmit a first scheduling request;
• receive signaling from a network node, the signaling comprising a grant allocation carrying information identifying that a plurality status report messages are permitted to be transmitted by the wireless device, the information comprising:
• an indication of a first number of device-to-device buffer status reports (BSRs) permitted to be transmitted by the wireless device;
• and
• an indication of a second number of cellular BSRs permitted to be transmitted by the wireless device;
• and
• transmitting the plurality of status report messages, each of the plurality of status report messages comprising:
• a device-to-device BSR indicating an amount of data to be transmitted on the device-to-device link;
• and
• a cellular BSR indicating an amount of data to be transmitted on the cellular link.

A method for allocating resources for device-to-device communications in a wireless communications network, the method comprising:

• transmitting signaling, by a network node, of a transmission schedule, the transmission schedule comprising:
• a first plurality of transmission opportunities for scheduling requests allocated to a device-to-device link;
• and
• a second plurality of transmission opportunities for scheduling requests allocated to a cellular link;
• during a transmission opportunity within the first plurality of transmission opportunities or the second plurality of transmission opportunities, receiving a first scheduling request;
• in response to the scheduling request, transmitting, to a first wireless device, signaling comprising a grant allocation carrying information identifying that a plurality of status report messages are permitted to be transmitted by the wireless device, wherein the information identifying that the plurality of status report messages may be transmitted by the wireless device in response to the scheduling request comprises:
• an indication of a first number of device-to-device buffer status reports (BSRs) permitted to be transmitted by the wireless device;
• and
• an indication of a second number of cellular BSRs permitted to be transmitted by the wireless device;
• and
• receiving, from the first wireless device, the plurality of status report messages, each of the plurality of status report messages comprising:
• a device-to-device BSR indicating an amount of data to be transmitted on the device-to-device link;
• or
• a cellular buffer BSR indicating an amount of data to be transmitted on the cellular link.

A network node for providing IP address translation services, the network node comprising:

• a memory storing instructions;
• and
• one or more processors in communication with the memory, the one or more processors operable to execute the instructions to cause the one or more processors to:
• transmit signaling of a transmission schedule, the transmission schedule comprising:
• a first plurality of transmission opportunities for scheduling requests allocated to a device-to-device link;
• and
• a second plurality of transmission opportunities for scheduling requests allocated to a cellular link;
• during a transmission opportunity associated with the first plurality of transmission opportunities or the second plurality of transmission opportunities, receive a first scheduling request;
• transmit, to a first wireless device, signaling comprising a grant allocation carrying information identifying that a plurality of status report messages are permitted to be transmitted by the first wireless device, wherein the information identifying that the plurality of status report messages may be transmitted by the wireless device in response to the scheduling request comprises:
• an indication of a first number of device-to-device buffer status reports (BSRs) permitted to be transmitted by the wireless device;
• and
• an indication of a second number of cellular BSRs permitted to be transmitted by the wireless device;
• and
• receive, from the first wireless device, the plurality of buffer status report messages, each buffer status report message comprising:
• a device-to-device BSR indicating an amount of data to be transmitted on the device-to-device link;
• or
• a cellular BSR indicating an amount of data to be transmitted on the cellular link.
