1. A user equipment (UE) in a hybrid communication network, comprising:
- a controller; and
a transceiver, wherein the controller is configured to cause the transceiver to;
transmit a scheduling request to a first eNodeB (eNB), wherein the scheduling request indicates that the UE is capable of device-to-device (D2D) communications;
receive a scheduling assignment (SA) from the first eNB, wherein the SA indicates resources to be used by a first UE for device-to-device (D2D) communications with the first eNB, wherein the SA includes a retransmission time pattern index that is associated with a retransmission time pattern indicator;
wherein the SA indicates a D2D transmission time domain pattern, including periodicity of a D2D data transmission burst, and a period of transmission and retransmission of a D2D transport block; and
wherein the SA indicates a first set of frequency domain resources for control or SA transmissions, and also indicates a second set of frequency domain resources for transmissions of D2D transport blocks or data, andcommunicate with the first eNB according to the SA.

Abstract
A user equipment, apparatus, and method are provided for wireless communication in a hybrid communication network. A method includes transmitting, by a first user equipment (UE), a scheduling request to a first eNodeB (eNB). The scheduling request indicates that the UE is capable of device-to-device (D2D) communications. The method includes receiving, by the first UE, a first scheduling assignment (SA) from the first eNB. The first SA indicates resources to be used by the first UE for device-to-device (D2D) communications with the first eNB. The method includes communicating, by the first UE, with the first eNB according to the first SA.
