1. A method for signaling an ad-hoc group of mobile units (MUs), the method comprising:
deriving a mobile unit group identifier (MUGI) by combining individual mobile unit identifiers (MUIs) of a plurality of MUs for which signaling awaits transmission via a wireless communication resource; and
transmitting, via the wireless communication resource, combined signaling comprising the derived MUGI, wherein the combined signaling comprises the MUGI and at least one paging indicator selected from the group consisting of:
an indication of whether an acknowledgment to a response to the combined signaling is to be requested by a responding MU,
an indication of what type of signaling in response to the combined signaling is requested from a responding MU,
an indication of a persistence level with which a responding MU should respond to the combined signaling,
an indication of a communication service to which the combined signaling pertains,
an indication to switch to an unslotted mode,
an indication to switch to a semi-dormant mode,
an indication to switch to a page monitoring mode using a reduced slot cycle index, and
an indication of whether the combined signaling is a last combined signaling in a present paging slot.
