Reduced power consumption in a wireless communication system while providing adequate directional radio coverage
First Claim
1. An arrangement for a wireless communication system, comprising:
- a set of power amplifiers and a set of antennas;
the set of power amplifiers and the set of antennas jointly having at least two different configurations, including a first configuration and a second configuration;
switching circuitry configured to switch between the configurations;
wherein the second configuration employs a smaller number of power amplifiers than the first configuration;
wherein the second configuration has fewer power amplifiers than antennas, with at least one power amplifier connected to at least two antennas via respective antenna branches that are configured with different delays;
wherein a difference in delay between a pair of the antenna branches is based on a measure representative of the inverse bandwidth of a signal to be transmitted through the antennas.

Abstract
There is provided an arrangement for a wireless communication system that includes a set of power amplifiers and a set of antennas based on which at least two different configurations are provided, including a first configuration of power amplifiers and antennas and a second configuration of power amplifier(s) and antennas. The arrangement also includes switching circuitry configured to switch between the configurations. The second configuration employs a smaller number of power amplifiers than the first configuration, and the second configuration has fewer power amplifiers than antennas where at least one power amplifier is connected to at least two antennas via respective antenna branches that are configured with different delays, as represented by delay elements. A difference in delay between a pair of these antenna branches is based on a measure representative of the inverse bandwidth of a signal to be transmitted through the antennas.
