In some embodiments, a method includes receiving, at a first wireless device of a plurality of wireless devices, a data packet including an indication of a source of the data packet. In response to the first wireless device being associated with the source of the data packet, whether the first wireless device is a local repeater can be determined based on at least one of a random number or a number of wireless devices of the plurality of wireless devices. In response to the first wireless device being determined to be a local repeater, the first wireless device can be caused to be configured as a local repeater such that the first wireless device sends the data packet to at least one remaining wireless device of the plurality of wireless devices.

A method for secure path discovery in a mesh network at a destination device is disclosed. The method includes receiving a path discovery request from an originator device and selecting a path selection in response to the path discovery request. The method also includes transmitting the path selection to the originator device and receiving a random seed from a provisioner device. The method also includes generating an authentication code based on the random seed, transmitting an authentication code message to an originator device and receiving communications from the originator device only if the originator device receives a verification response message from the provisioner device which confirms that the destination device has been verified.

Systems and methods configured for supporting multi-hop communications are described. Embodiments provide unavailable packet signaling by a base station aiding a multi-hop communication link. For example, the base station may transmit a predetermined “unavailable” message (e.g., an explicit and affirmatively transmitted message having predetermined content and/or format transmitted according to the schedule of the failed message) when an uplink data transmission in a multi-hop communication link fails or is otherwise currently unavailable. The unavailable packet signaling may be provided in association with a semi-persistent scheduling (SPS) and control channel scheduled retransmission technique, such as for supporting Internet of things (IoT), such as industrial Internet of things (IIoT), traffic. Other aspects and features are also claimed and described.

Methods and apparatuses for facilitating the use of stations (STAs) of a multi-link device (MLD) to set up and operate backhaul links to serve a Mobile access point (AP) within the same MLD in a wireless local area network. The apparatuses include an MLD comprising APs forming a Mobile AP MLD, backhaul STAs, and a processor operably coupled to the APs and the backhaul STAs. The processor is configured to instruct at least one of the APs to set up an access link with a corresponding STA of a non-AP MLD, and to instruct at least one of the backhaul STAs to set up a backhaul link with a corresponding AP of an AP MLD to carry traffic of the non-AP MLD that flows through the Mobile AP MLD over the access link.

A method and device are disclosed for PC5 Signaling (PC5-S) message reception from the perspective of a UE-to-UE relay. The UE-to-UE relay receives a first PC5-S message on a first sidelink Signal Radio Bearer (SRB) from a first UE, wherein the first PC5-S message is used to establish a first sidelink security between the UE-to-UE relay and the first UE, to update link identifier(s) associated with a first link between the first UE and the UE-to-UE relay, or to modify the first link between the first UE and the UE-to-UE relay. The UE-to-UE relay also delivers the first PC5-S message to an upper layer of the UE-to-UE relay.
