Abstract
The disclosure relates to a method performed by a UE, for using subframes of a radio access network for a D2D communication. The method comprises determining subframes available for D2D communication among subframes of the radio access network. The subframes available for D2D communication exclude a number of subframes of the radio access network, such that a periodicity of the D2D communication in number of subframes divides the number of subframes available for D2D communication. The method also comprises using the determined subframes for enabling D2D communication.
Claims23
A method performed by a user equipment (UE) for using subframes of a radio access network for Device-to-Device (D2D) communication, the method comprising:
- determining a set of subframes available for use in the D2D communication from among subframes of the radio access network other than those used for special purposes, such that the set of subframes available for the D2D communication excludes a number of subframes of the radio access network, such that a periodicity of the D2D communication in number of subframes evenly divides the number of subframes in the set;
- and
- using the determined subframes for enabling the D2D communication.
A user equipment (UE) configured for using subframes of a radio access network for enabling Device-to-Device (D2D) communication, the UE comprising:
- a radio transceiver circuitry configured to communicate wirelessly with another UE;
- processing circuitry operatively associated with the transceiver circuitry;
- and a memory operatively associated with the processing circuitry, wherein the memory comprises instructions executable by the processing circuitry whereby said UE is configured to:
- determine a set of subframes available for use in the D2D communication from among subframes of the radio access network other than those used for special purposes, such that the set of subframes available for the D2D communication excludes a number of subframes of the radio access network, such that a periodicity of the D2D communication in number of subframes evenly divides the number of subframes in the set;
- and
- use the determined subframes for enabling the D2D communication.
A non-transitory computer-readable medium comprising, stored thereupon, a computer program comprising computer readable code that, when executed on a processor of a user equipment (UE), causes the UE to:
- determine a set of subframes available for use in the D2D communication from among subframes of the radio access network other than those used for special purposes, such that the set of subframes available for the D2D communication excludes a number of subframes of the radio access network, such that a periodicity of the D2D communication in number of subframes evenly divides the number of subframes in the set;
- and
- use the determined subframes for enabling the D2D communication.
