One logical channel corresponds to one radio physical channel.

The composite material is crosslinked by physical or chemical means.

As such, the frame structures for both the common physical (random access) uplink channel and dedicated physical (traffic) uplink channel are compatible.

Beam alignment may be physically or electronically adjustable.

A radio physical channel can be shared by a plurality of logical channels.

Reaction column by physical or physico-chemical process in the heterogeneous phase.

Extraction of the CO2 from the air can be done chemically or physically.

The fuel preferably comprises algae which are physically and chemically unaltered.

Starches, and starches modified by physical means or by enzymes

An uplink common physical channel (random access channel) frame structure is disclosed with a separate preamble and data portion.

As a further advantage, the transmission capacity of the physical channel can be economically utilized.

These joints feature an overlap area (12) which can be affixed by physical or chemical means.

Information is selectively communicated on a second channel, e.g., a dedicated physical channel, to limit interference attributable to the synchronization code in a signal received over the second channel.

The elaboration concepts rely on the association of entities of different nature, by chemical or physical ways.

Two approaches are possible : the chemical one by sol-gel methods, the physical way by deposition (PVD).
