Abstract
A technology for a user equipment (UE) that is operable to communicate in a device to device (D2D) network. A D2D coordinator selection assignment can be determined. A D2D bandwidth allocation request can be received from at least one D2D UE. Bandwidth can be scheduled for the at least one D2D UE. A D2D bandwidth allocation message can be communicated to at least one D2D UE within the D2D network to enable the at least one D2D UE to determine when bandwidth is allocated for the at least one D2D UE to communicate with another D2D UE in the D2D network.
Claims30
A user equipment (UE) operable to communicate in a device to device (D2D) network, having computer circuitry configured to:
- determine a D2D coordinator selection assignment;
- receive a D2D bandwidth allocation request from at least one D2D UE;
- schedule bandwidth for the at least one D2D UE;
- and
- communicate a D2D bandwidth allocation message to at least one D2D UE within the D2D network to enable the at least one D2D UE to determine when bandwidth is allocated for the at least one D2D UE to communicate with another D2D UE in the D2D network.
A user equipment (UE) operable to communicate in a device to device (D2D) network, having computer circuitry configured to:
- transmit a D2D bandwidth allocation request to a D2D coordinator UE;
- receive a D2D bandwidth allocation message from the D2D coordinator UE;
- and
- transmit data from the UE to an other D2D UE at a selected time based on information received in the D2D bandwidth allocation message.
A user equipment (UE) operable to communicate in a device to device (D2D) network, having computer circuitry configured to:
- receive a D2D bandwidth allocation message from a D2D coordinator UE;
- identify reception information for receiving data from another D2D UE in the D2D network using the bandwidth allocation message;
- and
- receive the data from the other D2D UE using the reception information.
A method for coordinating device to device (D2D) communication, comprising:
- receiving a D2D coordinator selection assignment at a D2D coordinator UE;
- receiving a D2D bandwidth allocation request from a plurality of D2D transmitter UEs at the D2D coordinator UE;
- scheduling a bandwidth allocation for each of a plurality of D2D UEs;
- and
- communicating a D2D bandwidth allocation message to the plurality of D2D UEs within the D2D network, wherein D2D bandwidth allocation message enables the plurality of D2D UEs to determine the bandwidth allocation for each of the D2D UEs to communicate with at least one other D2D UE in the D2D network.
