Abstract
A method, in a telecommunications system, for transmitting radio signals from a base station comprising at least a pair of transmission branches configured to supply output signals for respective antennae of the base station, to at least one terminal comprising at least one antenna, the method comprising splitting a signal for transmission into at least first and second components, applying a phase shift to the first component to generate a modified first component and providing the modified first component and the second component to respective power amplifiers for transmission over the antennae.

A method, in a telecommunications system, for transmitting radio signals from a base station comprising at least a pair of transmission branches configured to supply output signals for respective antennae of the base station, to at least one terminal comprising at least one antenna, the method comprising:
- splitting a signal for transmission into at least first and second components;
- applying a phase shift to the first component to generate a modified first component;
- and
- providing the modified first component and the second component to respective power amplifiers for transmission over the antennae.
A system for transmitting radio signals, the system comprising:
- a remote radio head comprising at least a pair of transmission branches configured to supply output signals for respective antennae of a base station, wherein the remote radio head is operable to split a signal for transmission into at least first and second components and apply a phase shift to the first component to generate a modified first component;
- and
- provide the modified first component and the second component to respective power amplifiers of the system for transmission over the antennae.
A remote radio head apparatus in a telecommunications system, the remote radio head comprising at least a pair of transmission branches configured to supply output signals for respective antennae of a base station of the system, wherein the remote radio head is operable to split a signal for transmission into at least first and second components and apply a phase shift to the first component to generate a modified first component;
- and
- provide the modified first component and the second component to respective power amplifiers of the system for transmission over the antennae.
A base station in a telecommunications system, the base station comprising a remote radio head comprising at least a pair of transmission branches configured to supply output signals for respective antennae of a base station of the system, wherein the remote radio head is operable to split a signal for transmission into at least first and second components and apply a phase shift to the first component to generate a modified first component;
- and
- provide the modified first component and the second component to respective power amplifiers of the system for transmission over the antennae.
