Abstract
A method and an apparatus for monitoring device-to-device (D2D) transmission in a connected state in a communication system supportive of a D2D scheme are provided. The method includes monitoring, by a D2D user equipment (UE), a D2D transmission during a D2D resource cycle and a discontinuous reception (DRX) cycle in a radio resource control (RRC) state, transmitting an indication including a capability of the UE to a base station, and reestablishing an RRC connection from the base station, wherein the D2D resource cycle and the DRX cycle are configured not to overlap each other based on the indication.
Claims20
A method for device-to-device (D2D) communication by a D2D user equipment (UE), the method comprising:
- transmitting an indication of interest to D2D monitoring of the D2D UE;
- receiving, from the base station, a discontinuous reception (DRX) configuration;
- and
- monitoring D2D transmission from another UE based on the DRX configuration,
- wherein the D2D transmission is monitored by using a DRX cycle or a receiver (Rx) chain.
A device-to-device (D2D) user equipment (UE) comprising:
- a transceiver;
- and
- a processor configured to:
- control the transceiver to transmit, to a base station, an indication interest to D2D monitoring of the D2D UE,
- control the transceiver to receive, from the base station, a discontinuous reception (DRX) configuration, and
- monitor D2D transmission from another UE based on the DRX configuration,
- wherein the D2D transmission is monitored by using a DRX cycle or a receiver (Rx) chain.
A method for device-to-device (D2D) communication by a base station, the method comprising:
- receiving, from a D2D user equipment (UE), an indication of interest to D2D monitoring of the D2D UE;
- generating a discontinuous reception (DRX) configuration;
- and
- transmitting, to the D2D UE, the generated discontinuous reception (DRX) configuration,
- wherein D2D transmission from another UE is monitored by the D2D UE based on the generated DRX configuration, and
- wherein the D2D transmission is monitored by using a DRX cycle or a receiver (Rx) chain.
A base station comprising:
- a transceiver;
- and
- a processor configured to:
- control the transceiver to receive, from a device-to-device (D2D) user equipment (UE), an indication of interest D2D monitoring of the D2D UE,
- generate a discontinuous reception (DRX) configuration, and
- control the transceiver to transmit, to the D2D UE, the generated discontinuous reception (DRX) configuration,
- wherein D2D transmission from another UE is monitored by the D2D UE based on the generated DRX configuration, and
- wherein the D2D transmission is monitored by using a DRX cycle or a receiver (Rx) chain.
