Claim of US Patent No. 10,462,802

1. A first wireless transmit/receive unit (WTRU) comprising:a processor;
a memory comprising instructions that when executed by the processor cause the first WTRU to:
determine whether the first WTRU has D2D data to transmit to a second WTRU; and
on a condition that the first WTRU has D2D data to transmit to the second WTRU:
autonomously select a subset of scheduling assignment (SA) resources for transmission of an SA to the second WTRU from a pre-configured set of allowed SA resources,
transmit the SA to the second WTRU according to a first transmission period using the autonomously selected subset of SA resources;
determine a set of allowed device-to-device (D2D) data resources for D2D data transmission to the second WTRU,
autonomously select one or more transmission patterns for D2D data transmission to the second WTRU,
autonomously select one or more transmission parameters for D2D data transmission to the second WTRU, and
transmit D2D data to the second WTRU over the set of allowed D2D data resources according to a second transmission period using the autonomously selected one or more transmission patterns, and according to the autonomously selected one or more transmission parameters.
