METHODS, APPARATUS, AND SYSTEMS FOR SUPPORTING COORDINATED TRANSMISSIONS FOR COLLABORATIVE USER EQUIPMENT (UEs)

A first wireless/transmit receive unit (WTRU) of a WTRU group, the first WTRU comprising:

• a processor and a transceiver operatively coupled to the processor;
• the transceiver configured to receive, from a network, configuration information indicating WTRU identifiers (IDs) for one or more WTRUs in the WTRU group, one or more configured grants (CGs) associated with the one or more WTRUs in the WTRU group, and a threshold value;
• the processor configured to:
• based on a time that the first WTRU receives data from an application for a respective WTRU in the WTRU group, determine respective timing information associated with an actual reception of the data and an expected reception of the data from the application;
• determine that the respective timing information is above the threshold value;
• and
• select, for the respective WTRU(s) in the WTRU group, at least one respective configured grant (CG) from the one or more configured grants (CGs) based on the determined respective timing information;
• and
• the transceiver configured to indicate the selected at least one respective configured grant (CG) and associated WTRU identifier (ID) of the respective WTRU(s) to the network.
