scope:
This document defines the radio (RF), Physical Layer (PHY), Medium Access Control (MAC), and Layer 3 (L3) specifications for the HC-SDMA (High Capacity - Spatial Division Multiple Access) protocol.
This specification does not address functionality at the service and application layers. Typical deployments are expected to use a standardized data networking access paradigm, such as L2TP and PPP.
Purpose
HC-SDMA provides wide-area broadband wireless data-connectivity for fixed, portable, and mobile computing devices and appliances that may or may not be handheld. The protocol is designed to be implemented with antenna array techniques to substantially improve the RF coverage, capacity, and performance of the system.
Specifically, the HC-SDMA protocol:
♦ Specifies base station (BS) radio frequency characteristics such as output power levels, transmit frequencies and timing error, pulse shaping, in-band and out-of-band spurious emissions, receiver sensitivity and selectivity.
♦ Specifies user terminal (UT) radio frequency characteristics such as output power levels, transmit frequency and timing error, pulse shaping, in-band and out-of-band spurious emissions, receiver sensitivity and selectivity.
♦ Defines associated frame structures for the various burst types including standard uplink and downlink traffic, paging and broadcast burst types.
♦ Specifies the modulation, forward error correction, interleaving and scrambling for various burst types.
♦ Describes the various logical channels (broadcast, paging, random access, configuration and traffic channels) and their roles in establishing communication over the radio link.
♦ Specifies procedures for error recovery and retry.
♦ Describes Layer 3 (L3) mechanisms for creating and controlling logical connections (sessions) between user terminal and base station including registration, stream start, power control, handover, link adaptation, stream closure.
♦ Describes L3 mechanisms for user terminal authentication and secure transmission of on the uplink and downlink data links.
