Methods and apparatus for offline management of blockchain nodes are disclosed. A method performed by a first blockchain node may comprise transmitting, to at least a second blockchain node, a first message that includes information indicating a status of the first blockchain node and a value indicating a time at which the first block chain node will go offline; receiving, from the second blockchain node, a second message that includes information indicating a blockchain proxy node being selected for the first blockchain node; and transitioning to an offline status at the time indicated by the value.
A wireless transmit/receive unit (WTRU) may receive a downlink communication from a network over a first interface transmitted to one or more WTRUs in a group of WTRUs. The WTRU may determine an access class of the WTRU based on a packet loss percentage of the downlink communication. The access class may be associated with a contention window for accessing a second interface. The WTRU may transmit packet loss information to the one or more WTRUs over the second interface in the contention window. The WTRU may receive packet loss feedback from the one or more WTRUs over the second interface. The WTRU may determine that the access class of the WTRU is a highest class of the one or more WTRUs. The WTRU may transmit a single groupcast negative acknowledgement (gNACK) to the network on behalf of the one or more WTRUs over the first interface.
