摘要： A cellular communication system (100) comprises management logic (146) having broadcast mode logic (150) arranged to support a common cell identifier reuse pattern for broadcast transmissions amongst a cluster of communication cells. A plurality of wireless serving communication units is operably coupled to the management logic. At least one wireless communication unit comprises a receiver for receiving a broadcast signal from both a first serving wireless communication unit and a second serving wireless communication unit wherein both the first serving wireless communication unit and second serving wireless communication unit use a common cell identifier (215) reuse pattern for broadcast transmissions to be used by the at least one wireless communication unit in receiving broadcast communication across the cluster of communication cells. The at least one wireless communication unit further comprises logic arranged to detect the broadcast communication from both the first serving wireless communication unit and second serving wireless communication unit, where the broadcast communication is allocated to the first timeslot (350) or first sub-frame based on it being more robust to multipath delay due to temporal dispersion of the same broadcast signal from a plurality of wireless serving communication units.

摘要： Embodiments of the invention provide for allocating spectrum in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation. Logic is arranged for determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation. Logic for allocating spectrum allocates a temporary guard band between a first portion of spectrum for the first mode of operation and a second portion of spectrum for the second mode of operation for use while the wireless communication unit operates simultaneously in the first mode of operation and second mode of operation.

摘要： A method and arrangement (100) for PRACH burst channel detection in a UTRA TDD wireless communication system in which training sequences are constructed from a single periodic base code. Unwanted cross-correlation peaks, having magnitude less than correlation peaks, are removed (440) from the correlator outputs, maintaining optimal signal-to-noise ratio of the channel estimates, providing a low probability of false detection, and extending the cell size of a CDMA network to that determined by the guard period duration. The cell size can be extended further by ensuring that no transmissions are scheduled for the timeslot subsequent to that in which the channel estimation bursts are scheduled.
