Higher layer packet (HLP) framing information is transmitted across an air interface only as necessary, utilizing the Radio Link Protocol (RLP). In one embodiment, HLP framing information is transmitted in RLP control frames, between each HLP. In another embodiment, HLP framing information is transmitted in RLP data frames, with the RLP data frames including an indicator of that framing information. In three other embodiments, HLP framing information is transmitted in RLP data frames, and those RLP data frames containing HLP framing information are identified by RLP control frame functions. The control frame functions may comprise unnumbered RLP control frames, RLP data frames numbered using the RLP data frame sequence space but containing no HLP data, or RLP control frames numbered using an alternate sequence space.
