A network selects a transmission mechanism for delivering a Point to Multipoint (PTM) compatible service based on cell identification (cell ID) information identifying the serving cells of user equipment (UE) devices interested in receiving the PTM compatible service. In some situations, the cell ID information is obtained by the network using a Multimedia Broadcast Multicast Service (MBMS) counting procedure where cell ID information is requested in a MBMS Counting Request Message and provided by each UE device in a MBMS Counting Response Message.

During operation, the radio node may, using a first interface circuit, listen for transmissions from one or more second radio nodes. Based at least in part on the transmissions, the radio node may determine a first list of discovered channels associated with the radio node and the one or more second radio nodes. Then, the radio node may, using a second interface circuit, provide the first list of discovered channels to the one or more second radio nodes. Moreover, the radio node may, using the second interface circuit, receive one or more second lists of discovered channels from the one or more second radio nodes. Next, the radio node may aggregate the first list of discovered channels and the second list of discovered channels into a list of active channels. Furthermore, the radio node may, using the first interface circuit, provide the list of active channels to an electronic device.

A method in which a first apparatus performs wireless communication and an apparatus supporting the same are provided. The method may include: receiving information related to a physical sidelink feedback channel (PSFCH) resource from a base station; receiving a physical sidelink shared channel (PSSCH) from a second apparatus; and transmitting a PSFCH related to the PSSCH to the second apparatus. Here, the information related to the PSFCH resource may include, for example, information related to a resource block (RB) available for the first apparatus to transmit the PSFCH.

A system and method for collaborative broadcasting and bi-directional network transmission. Such a system may comprise a broadcast transmission source that uses a one-to-many broadcasting method, a bi-directional network that uses a one-to-one broadcasting method, and a receiver apparatus configured to receive broadcasts from the broadcast transmission source and communicate with the bi-directional network. When the receiver apparatus receives a broadcast from the broadcast transmission source, and when the broadcast is partially damaged or missing, the receiver apparatus is configured to communicate with the bi-directional network and request the damaged or missing data.

Disclosed is a method for a terminal transmitting a sidelink data channel in a wireless communication system. Particularly, the method comprises a step for transmitting a sidelink data channel having a first priority. The sum if resources which can be used for all sidelink data channels having a priority equal to or lower than the first priority is equal to or less than a threshold corresponding to the first priority.

A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID, acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.
