Abstract
Embodiments of an evolved Node B (eNB) and methods for determining priority values for User Equipment (UE) are generally described herein. A method performed by circuitry of an eNB may include receiving, at the eNB, a usage report from the UE. The usage report may include information indicating a channel usage time and a transmission power of the UE. The method may include determining, using the usage report, a priority value for the UE. The method may include sending the priority value to the UE, wherein the UE is to utilize the priority value to perform distributed scheduling of device-to-device (D2D) communication over a D2D connection with a second UE.
Claims28
An evolved Node B (eNB), the eNB comprising:
- hardware processing circuitry to:
- receive a usage report from a User Equipment (UE), wherein the usage report includes information indicating a channel usage time and a transmission power of the UE;
- determine, using the usage report, a priority value within a priority map for the UE by prioritizing lower channel usage time and lower transmission within the priority map;
- and
- send the priority value to the UE for use in device to device (D2D) communication with a second UE.
A User Equipment (UE), the UE comprising:
- processing circuitry to identify information about channel usage time and transmission power of the UE for use in device-to-device (D2D) communication with a second UE;
- and
- a transceiver, coupled to the processing circuitry to:
- transmit a usage report to a coordinator system, wherein the usage report includes the information about the channel usage time and the transmission power of the UE;
- receive, from the coordinator system, a priority value for the UE, wherein the priority value is a ranking in a priority map;
- and
- initiate communication over a D2D connection with the second UE using the priority value.
At least one machine-readable medium including instructions for operation of a computing system, which when executed by a machine, cause the machine to:
- receive, at an evolved Node B (eNB), a usage report from a User Equipment (UE), wherein the usage report contains information indicating a channel usage time and a transmission power of the UE;
- determine, using the usage report, a priority value for the UE;
- and
- send the priority value to the UE, wherein the UE is to utilize the priority value in communicating over a device to device (D2D) connection with a second UE.
A method performed by circuitry of an evolved node B (eNB), the method comprising:
- receiving, at the eNB, a usage report from a User Equipment (UE), wherein the usage report includes information indicating a transmission power and channel usage time of the UE;
- determining, using the usage report, a priority value for the UE, wherein the priority value indicates the UE has priority to communicate over a device to device (D2D) connection with a second UE;
- and
- evaluating the usage report to determine if a fairness metric for the UE is within a fairness range, and if the fairness metric is outside the fairness range, sending an indication to the UE to not initiate D2D communication with the second UE.
