Base station having a plurality of transmission

摘要

Resources are allocated among several transmission devices (UE) in a base station (BS). Additional spectral resources are provided for use when the existing resources are unavailable. Time division multiplexing is used in the mobile communication system. Each frequency channel is divided into 8 or 16 time periods (Full-rate or Half-rate). The additional resources are divided among at least two transmission devices for combined use. The additional resource includes at least one extra frequency channel for at least two directions of transmission. A modulator generates a frequency channel whose power is split into three for three transmission devices. A PIN diode may be used in place of the power divider.
