Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus receives a D2D resource message based on a change in an uplink-downlink subframe configuration of at least one frame. The D2D resource message enables the apparatus to determine D2D resources allocated for D2D transmissions after the change in the uplink-downlink subframe configuration. The apparatus determines a subset of the D2D resources to be used for performing D2D transmissions based on the received D2D resource message.
Claims30
A method of a wireless communication by a user equipment (UE), comprising:
- receiving a device-to-device (D2D) resource message based on a change in an uplink-downlink subframe configuration of at least one frame, wherein the D2D resource message enables the UE to determine D2D resources allocated for D2D transmissions and the number of radio frames for which the D2D resources are allocated after the change in the uplink-downlink subframe configuration;
- and
- determining a subset of the D2D resources in the number of radio frames to be used for performing D2D transmissions based on the received D2D resource message.
A method of wireless communication by a base station, comprising:
- determining to reconfigure an uplink-downlink subframe configuration of at least one frame based on network traffic;
- reconfiguring the uplink-downlink subframe configuration based on the determination;
- and
- transmitting a device-to-device (D2D) resource message based on the reconfigured uplink-downlink subframe configuration, wherein the D2D resource message enables a user equipment (UE) to determine D2D resources allocated for D2D transmissions and the number of radio frames for which the D2D resources are allocated based on the reconfigured uplink-downlink subframe configuration.
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive a device-to-device (D2D) resource message based on a change in an uplink-downlink subframe configuration of at least one frame, wherein the D2D resource message enables the apparatus to determine D2D resources allocated for D2D transmissions and the number of radio frames for which the D2D resources are allocated after the change in the uplink-downlink subframe configuration;
- and
- determine a subset of the D2D resources in the number of radio frames to be used for performing D2D transmissions based on the received D2D resource message.
An apparatus for wireless communication, comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- determine to reconfigure an uplink-downlink subframe configuration of at least one frame based on network traffic;
- reconfigure the uplink-downlink subframe configuration based on the determination;
- and
- transmit a device-to-device (D2D) resource message based on the reconfigured uplink-downlink subframe configuration, wherein the D2D resource message enables a user equipment (UE) to determine D2D resources allocated for D2D transmissions and the number of radio frames for which the D2D resources are allocated based on the reconfigured uplink-downlink subframe configuration.
