Reduction of concurrent signaling in a relay user equipment (UE)

An apparatus of a relay user equipment (UE) operable resolve predefined types of concurrent communications at the relay UE, the apparatus comprising one or more processors and memory configured to:

• receive, from an eNodeB, control signaling to resolve predefined types of communications performed at the relay UE to defined subframes;
• and
• perform the predefined types of communications with at least one of the eNodeB or a remote UE in accordance with the control signaling received from the eNodeB, wherein the control signaling provides concurrency avoidance at the relay UE for predefined types of concurrent communications at the relay UE;
• communicate, from the relay UE to a remote UE, sidelink control information that includes a set of parameters over a Physical Sidelink Control Channel (PSCCH) or a Physical Sidelink Shared Channel (PSSCH), wherein the set of parameters indicate Physical Sidelink Control Channel (PSCCH) resources (nPSCCH), time resource patterns (ITRP), and a modulation and coding scheme (IMCS), wherein:
• the set of parameters enable the remote UE to perform ProSe communications with the relay UE using a defined PSSCH resource pool;
• or
• the set of parameters enable the remote UE to utilize a defined PSSCH resource pool when performing a subsequent ProSe communication with the relay UE.

At least one non-transitory machine readable storage medium having instructions embodied thereon for resolving predefined types of concurrent communications for a relay user equipment (UE), the instructions when executed perform the following:

• identifying, using at least one processor at an eNodeB, the relay UE that is configured to relay proximity services (ProSe) traffic between the eNodeB and a remote UE, wherein:
• the relay UE is in-coverage of the eNodeB;
• and
• the remote UE is in-coverage or out-of-coverage of the eNodeB;
• and
• communicating, using at least one processor at the eNodeB, control signaling to at least one of the relay UE and the remote UE to resolve predefined types of communications performed at the relay UE or the remote UE to defined subframes, wherein the control signaling provides concurrency avoidance at the relay UE for predefined types of concurrent communications at the relay UE,
• wherein the control signaling communicated to at least one of the relay UE and the remote UE indicates a defined resource pool of subframes, wherein the relay UE is configured to resolve predefined types of concurrent communications with at least one of the eNodeB and the remote UE when utilizing subframes in the defined resource pool to perform one or more predefined types of communication.
