摘要:
A communication system having a plurality of common channels and includes a primary common control physical channel, a plurality of dedicated channels and a synchronization channel (SCH). The primary common control physical channel and the synchronization channel are transmitted time multiplexed, and the sum transmit power of dedicated channels is reduced during the transmission of the synchronization channel in order to keep the total output power at the base station power amplifier below a maximum power limit.

摘要:
An improved device for receiving and transmitting mobile telephony signals comprises at least 4 channels. Each of the at least 4 channels (K1, K2, K3, K4) can be controlled with a transmission signal, that is different from the other channels, which can be generated with a separate channel module (KM1, KM2, KM3, KM4) from various data streams. A controller device is provided for, via which several or all of the power amplifiers, which are connected in several or all channels (K; K1, K2, K3, K4), can be operated in-phase or phase-locked with each other, in such a way that the transmission signals (TX) amplified in the channels concerned (K; K1, K2, K3, K4) can be synchronized and interconnected. As a result, a transmission signal can be radiated with a higher transmission power.
