Regarding claim 15, Li discloses a first wireless terminal (WTRU, Fig. 35F), comprising: a communication unit (transceiver, Fig. 35F), configured to communicate with a second wireless terminal for a proximity service on a first communication path, and a processor (processor, Fig. 35F) configured to check a communication path policy after a communication path quality fails to satisfy at least one communication requirement of the proximity service, to determine whether to switch to a second communication path for the proximity service (proximity based services, Para [0003], UE can dynamically decide to choose the path, Para [0097], selecting path for UE to UE communication based on path selection policy that is sent to the UE, Para [0267], UE selects path based on different information such as QoS criteria or radio measurements, Para [0275], e.g. data rate performance degrades for 5GC path, the UE can switch to PC5 path, Para [0285]), wherein the first communication path is one of a direct communication path between the first wireless terminal and the second wireless terminal and an indirect communication path which involves a network and is between the first wireless terminal and the second wireless terminal, and the second communication path is another one of the direct communication path and the indirect communication path (UE can maintain two paths, one is Uu based and the other is PC5 based, Para [0097], path switch from direct path to indirect path and vice vera, Para [0006], UE to UE communication, Para [0267]). Regarding claim 16, Li discloses a wireless network node (enodeB, Fig. 35C), comprising: a communication unit (transceiver, inherent), configured to transmit, to a wireless terminal, a communication path policy no later than that the wireless terminal registering to a network through the wireless network node, wherein the communication path policy is associated with a path switching between a first communication path and a second communication path for at least one proximity service (UE may request a path selection policy during registration, Para [0267] proximity based services, Para [0003], UE can dynamically decide to choose the path, Para [0097], selecting path for UE to UE communication based on path selection policy that is sent to the UE, Para [0267]), wherein the first communication path is one of a direct communication path between the first wireless terminal and the second wireless terminal and an indirect communication path which involves the network and is between the first wireless terminal and the second wireless terminal, and the second communication path is another one of the direct communication path and the indirect communication path (UE can maintain two paths, one is Uu based and the other is PC5 based, Para [0097], path switch from direct path to indirect path and vice vera, Para [0006], UE to UE communication, Para [0267]). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claims 2-4, 6-9, 13, 14 and 17-20 are rejected under 35 U.S.C. 103 as being unpatentable over Li. Regarding claims 2 and 13, Li discloses the wireless communication method of claim 1/11, wherein the communication path policy comprises a mapping from at least one proximity service to at least one of the first communication path or the second communication path (policy information manages the QoS mapping over PC5, Para [0150], QoS rules associated with the PDU session, Para [0172]). Regarding claim 3, Li discloses the wireless communication method of claim 1, wherein the communication path policy indicates that the proximity service supports the second communication path, and wherein checking the communication path policy for the proximity service, to determine whether to switch the proximity service to the second communication path comprises: switching the proximity service to the second communication path (selecting path for UE to UE communication based on path selection policy that is sent to the UE, Para [0267], UE selects path based on different information such as QoS criteria or radio measurements, Para [0275], communication mode can indicate a preferred path, Para [0276], obvious variation path selection policy could indicate if second path is supported, otherwise it couldn’t switch to a path that isn’t supported).
