scope:

The present document specifies the HiperMAN air interface with the specification layer 1 (physical layer), which can be used to provide Fixed applications, in frequencies below 11 GHz, and Nomadic and converged Fixed-Nomadic applications, in frequencies below 6 GHz. The present document follows 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.

• It does cover the receiver and transmitter performance requirements which are specific for HiperMAN systems.

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