A wireless communication system includes a plurality of user devices, UEs, and at least one logical group defined in accordance with one or more logical group criteria. The logical group includes a plurality of member UEs to be connected via sidelink for sidelink communication with each other, and all member UEs of the logical group have assigned the same destination identification, ID, the destination ID being unique for the logical group.

Methods and apparatuses are described herein for multicast and unicast MAC address assignment protocol (MUMAAP). A first node may transmit, to a second node, based on a unicast MAC address of the second node or a multicast MAC address associated with the second node, a discover message that may include a first MAC address or a first range of MAC addresses. The first node may receive an offer message with a second range of MAC addresses. If the first node selects a second MAC address from the received second range of MAC addresses, the first node may transmit a request message indicating that the second MAC address or the second range of MAC addresses is allocated to the first node. The first node may receive an acknowledge message indicating that the second MAC address or the second range of MAC addresses is allocated to the first node.

An information processing device that is connected to a DNS server via a network in which the information processing device and the DNS server can communicate with each other comprising: a first confirmation unit that confirms if there is a duplication of a device name of the information processing device within the same local area network; a second confirmation unit that confirms if the device name of the information processing device is a duplicate of a device name registered in the DNS server if it is confirmed there is no duplication of the device name of the information processing device within the same local area network; and a registration unit that registers the device name of the information processing device in the DNS server if it is confirmed that the device name of the information processing device is not a duplicate of the device name registered in the DNS server.

An access point that selectively provides a multicast domain name system (mDNS) message is described. During operation, the access point may receive an mDNS message, where the mDNS message includes an identifier of a group (such as a user group). For example, the identifier of the group may be included in the mDNS message when the mDNS message includes discovery information for a service. Moreover, the identifier may specify the portion of a subnet in a wireless local area network (WLAN) in a geographic region, such as a room, a floor or a building. Then, the access point may determine whether the access point or an electronic device is included in the group. When the access point or the electronic device is in the group, the access point may selectively provide the mDNS message addressed to the electronic device. Otherwise, the access point may drop the mDNS message.

An apparatus for helping with multicast domain name service (MDNS) discovery includes one or more processors configured to receive a first MDNS query from the resource seeking device, receive a first MDNS response from the resource providing device, and generate a second MDNS response according to the first MDNS response. The second MDNS response is generated at least by including a resource record from the first MDNS response and setting a time-to-live (TTL) value of the resource record in the second MDNS response to be lower than an original TTL value as specified for the resource record in the first MDNS response. The second MDNS response is sent to the resource seeking device in response to the first MDNS query. A hospitality establishment may thereby soft assign a media device to a user device while retaining the ability to change the media device assigned to the user device.

In one embodiment, a method is provided. The method includes determining that a network device should use an underlay multicast group associated with an overlay multicast group for multicast traffic. The underlay multicast group carries multicast traffic for the overlay multicast group. The overlay multicast group is associated with a virtual private network. The method also includes determining an underlay multicast group address for the underlay multicast group. The overlay multicast group is associated with an overlay multicast group address. A first portion of the underlay multicast group address is a function of the overlay multicast group address. The method further includes forwarding one or more multicast packets to one or more multicast receivers via the underlay multicast group using the underlay multicast group address.

Techniques herein facilitate policy-based wireless infrastructure-initiated device address rotations for wireless devices of a wireless local area network (WLAN). In one example, a method may include obtaining device information for a plurality of wireless devices connected to the wireless network infrastructure; associating a first wireless device of the plurality of wireless devices with a Media Access Control (MAC) address rotation policy based on device information obtained for the first wireless device; determining that a MAC address rotation is to be performed for the first wireless device based on the MAC address rotation policy; and triggering the MAC address rotation for the wireless device via the wireless network infrastructure.
