Registration and discovery via a network function

Abstract

A wireless transmit / receive unit (WTRU) may send a sensing request message, for example to a network. The sensing request message may include an indication of sensing criteria, for example associated with device to device (D2D) sensing services. The WTRU may receive a sensing response message, for example from the network. The sensing response message may include an indication associated with another WTRU. The WTRU may send a discovery request, for example to the network. The discovery request may include an indication of one or more one D2D sensing capabilities of the other WTRU. The WTRU may receive a proximity service (ProSe) code, for example in response to the discovery request. The ProSe code may be associated with the other WTRU. The ProSe code may include the indication of the at least one D2D sensing capabilities of the other WTRU.
