Introduction
GPRS-136 is the packet data service provided in TIA/EIA-136(also known as UWC-136). A general description of the SystemArchitecture and Protocol Descriptions is provided inTIA/EIA-136-330.
To provide very high data rates, GPRS-136 uses a 1.6 MHz bearerchannel, also known as 136HS Indoor. The upper layers of theGPRS-136 protocol stack are common throughout UWC-136, applying toeach individual bearer (136+, 136HS Outdoor, and 136HS Indoor).This document provides an Overview of the 136HS Indoor bearerchannel, configured as a traffic channel (PTCH), for GPRS-136. AnRLC/MAC entity for the 136HS Indoor bearer channel is specified inTIA/EIA-136-362 and a Physical Layer is specified inTIA/EIA-136-361.
Two implementation modes are defined. A Frequency DivisionDuplex (FDD) mode uses separate RF channels for the Mobile Stationtransmitter and the Base Station transmitter, thus allowing both totransmit simultaneously. In the Time Division Duplex (TDD) mode asingle RF channel is used by both the Mobile Station transmitterand the Base Station Transmitter, which requires that the MobileStation and Base Station transmit alternately, thus sharing the RFresource in time.
