Shape.
By taking K=2 (that is, 2 groupings) as an example, then S=1, can be used only " R " bit in 2 " R " bits
Indicate this 2 groupings, for example, " R " bit is 0 grouping being used to indicate in this 2 groupings, " R " bit is 1 for referring to
Show another grouping in this 2 groupings.
It is being in K grouping of instruction by the combination settings of at least one of MAC PDU subheader portion " R " bit and LCID
In each grouping, bit number S needed for being used to indicate the packet identification information that this K is grouped can be first determined, wherein S=
ceiling(log2K)；Then, it sets at least one of MAC PDU subheader portion " R " bit to carrying packet identification letter
A part of breath, and the LCID that at least one of MAC PDU subheader portion retains is set to indicate that the packet identification information
Remainder.
By taking K=4 (that is, 4 grouping) as an example, then S=2, " R " bit and 2 reservations can be used
LCID come indicate this 4 grouping.
3rd embodiment
In this embodiment, it is first determined bit needed for being used to indicate the timing advance group mark of M timing advance group
