scope:

The present document specifies the HIPERMAN air interface with the specification layer 1 (physical layer), following the ISO-OSI model. HIPERMAN is confined only to the radio subsystems consisting of the physical (PHY) layer and the DLC layer - which are both core network independent - and the core network specific convergence sub-layer.

For managing radio resources and connection control, the data link control (DLC) protocol is applied, which uses the transmission services of the DLC layer. Convergence layers above the DLC layer handle the inter-working with layers at the top of the radio sub-system.

The scope of the present document is as follows:

• It gives a description of the physical layer for HIPERMAN systems.

• It specifies the transmission scheme in order to allow interoperability between equipment developed by different manufacturers. This is achieved by describing scrambling, channel coding, modulation, framing, control mechanisms, and power control to assist in radio resource management.

• The specification includes receiver requirements, transmitter requirements, frequency and timing requirements, and radio frequency channel plans necessary for radio regulatory purposes.

• Some information clauses and annexes describe parameters and system models to assist in preparing conformance, interoperability, and coexistence specifications.
