Abstract

The UMTS Terrestrial Radio Access (UTRA) air interface consists of two modes, a frequency division duplex (FDD) mode and a time division duplex (TDD) mode. The different modes operate in the paired and in the unpaired frequency band respectively. This paper analyses different radio resource allocation schemes for the broadcast control channel (BCCH) in the TDD mode of UTRA.. The investigations concern the performance of the BCCH as well as the performance of the served downlink speech connections. Simulations show that one of the 15 time slots in the TDMA frame should be allocated entirely for the BCCH. Compared to a resource allocation scheme where traffic channels (TCHs) and the BCCH are mixed in the same time slot, this is advantageous both for the BCCH and the TCHs. However, the measure excludes 1/15 of the available resources for traffic utilization
