Abstract
A D2D communication method and a D2D communication apparatus are provided. The method includes: obtaining, by a first UE, a TDD uplink and downlink configuration and a D2D resource configuration strategy for resource configuration in the case that the first UE determines that no cell is detected; allocating, by the first UE, resources for the D2D communication based on the TDD uplink and downlink configuration and the D2D resource configuration strategy; and performing, by the first UE, the D2D communication based on the allocated resources for the D2D communication.
Claims19
A Device-to-Device (D2D) communication method for D2D communication by using an authorized Time Division Duplexing (TDD) carrier, comprising:
- obtaining, by a first User Equipment (UE), TDD uplink and downlink configuration and a D2D resource configuration strategy for resource configuration in the case that the first UE determines that no cell has been detected;
- allocating, by the first UE, resources for the D2D communication based on the TDD uplink and downlink configuration and the D2D resource configuration strategy;
- and
- performing, by the first UE, the D2D communication based on the allocated resources for the D2D communication.
A Device-to-Device (D2D) communication apparatus for D2D communication by using an authorized Time Division Duplexing (TDD) carrier, comprising:
- an obtaining unit, configured to obtain TDD uplink and downlink configuration and a D2D resource configuration strategy for resource configuration in the case that no cell has been detected;
- a D2D resource allocating unit, configured to allocate resources for the D2D communication based on the TDD uplink and downlink configuration and the D2D resource configuration strategy;
- and
- a communication unit, configured to perform the D2D communication based on the allocated resources for the D2D communication.
A Device-to-Device (D2D) communication apparatus, comprising:
- a processor;
- a memory connected to the processor via a bus interface and configured to store therein programs and data for the operation of the processor,
- wherein in the case that the programs and data stored in the memory are called and executed by the processor, the processor is configured to achieve the functional modules of:
- an obtaining unit configured to obtain a Time Division Duplexing (TDD) uplink and downlink configuration and a D2D resource configuration strategy for resource configuration in the case that no cell has been detected;
- a D2D resource allocating unit configured to allocate resources for the D2D communication based on the TDD uplink and downlink configuration and the D2D resource configuration strategy;
- and
- a communication unit configured to perform the D2D communication based on the allocated resources for the D2D communication.
