Title (EN) A METHOD AND APPARATUS FOR DYNAMIC TRANSMITTER TO MULTI-CARRIER POWER AMPLIFIER MAPPING
(FR) PROCÉDÉ ET APPAREIL DE MISE EN CORRESPONDANCE DYNAMIQUE D'UN ÉMETTEUR À UN AMPLIFICATEUR DE PUISSANCE MULTIPORTEUSE
Abstract:
(EN) According to the teachings presented herein, dynamic mapping is used to determine which multi-carrier power amplifiers (MCPAs) provide the required transmit power for individual ones of the transmitters in a base station. With dynamic mapping, the required transmit power of any one or more of the transmitters can be distributed to more than one MCPA, providing for more efficient 'packing' of required transmit powers into the available transmit powers of the MCPAs, and/or providing for power mapping based on any one or more mapping criterion, As a non-limiting advantage, the dynamic mapping presented herein reduces the number of MCPAs needed to support a given number of transmitters.
(FR) Selon la présente invention, une mise en correspondance dynamique est utilisée pour déterminer quels amplificateurs de puissance multiporteuse (MCPA) fournissent la puissance d'émission requise pour des émetteurs individuels parmi les émetteurs d'une station de base. Avec une mise en correspondance dynamique, la puissance d'émission requise d'un ou plusieurs quelconques des émetteurs peut être distribuée à plus d'un MCPA, assurant un « remplissage » plus efficace des puissances d'émission requises dans les puissances d'émission disponibles des MCPA, et/ou assurant une mise en correspondance de puissance sur la base d'un ou plusieurs critères de mise en correspondance quelconques. A titre d'avantage non limitant, la mise en correspondance dynamique présentée ici réduit le nombre de MCPA nécessaires pour supporter un nombre donné d'émetteurs.
