Abstract: An adaptive antenna array (14) includes a multiplicity of antenna elements (12a-12k, 48a-48k) responsive to uplink communications (16a-16k) and arrange d to support directional-orientated downlink communication to subscriber units (18). The adaptive antenna array (14) is operationally responsive to a signa l processor (28) that co-operates with direction of arrival estimation logic (36) to assess an angle of arrival of uplink communications incident to the array. To avoid inter-cell interference, especially during early stages of a call, the signal processor operates to ensure that a wide area downlink beam (108) is provided for a downlink path to an addressed subscriber unit. With time and/or with reported (68,84) downlink quality of service (QoS) metrics, the signal processor (28) regulates (74, 92, 96) a width of the downlink bea m by altering the number of antenna elements used to support the downlink beam , thereby altering the downlink beam aperture. Generally, with time, more antenna elements (92) are used and so the beam is narrowed, although in-call fluctuations in downlink quality of service are dynamically addressed.

Abstract: Método (200) para controlar la potencia de transmisión de un transceptor (70, 100) de un sistema de comunicaciones celulares que comprende una pluralidad de celdas (80, 88, 90) en al menos dos de las celdas que tienen equipos de estaciones base (22-32), y que también comprende un equipo de estaciones base co-ubicadas compatibles con una pluralidad de interfaces aéreas diferentes controlables mediante una unidad transceptora, dicho método que comprende: evaluar un entorno de interferencia que surge de la utilización de al menos una primera interfaz aérea en al menos dos de la pluralidad de celdas; inferir (208) condiciones de propagación que probablemente se experimentarán dentro de una segunda interfaz aérea en base al entorno de interferencia evaluado; y controlar (212) las configuraciones de transmisión de potencia dentro de la segunda interfaz aérea en base a dichas condiciones de propagación inferidas.

Abstract: A method of enhancing a communication capability of a communication unit (112), operating in a communication system (100) that facilitates communication to and/or from a plurality of communication units, is described. The method includes the step of operably coupling a first communication unit (112) to one or more neighbouring communication units (114, 116) such that said communication unit is able to utilise at least one operational capability of one or more of its neighbouring communication units to enhance communication to and/or from said first communication unit. This provides the advantage that a collective use of neighbouring communication units, for example formed in an aggregate group, provide a more reliable uplink and/or downlink communication link without using more network resources. In particular, the transmitting/receiving communication unit is able to utilise functionality in neighbouring communication units to which it can be operably connected. Furthermore, the wireless or wired communication link efficiency is improved and higher data rate throughput can be realized.
