Abstract
The invention relates to transmission from a base station to a receiver, the base station comprising first radiating means arranged for transmitting according to an antenna pattern with respect to the receiver and further comprising second radiating means arranged for transmitting according to the same antenna pattern as the first radiating means with respect to the receiver, the transmissions of the first and second radiating means being time shifted by a determined duration.
Claims24
A method of transmitting from a base station to another station, the base station comprising a first antenna assembly having plural radiating elements and a second antenna assembly having plural radiating elements, the method comprising:
- transmitting a first signal from the first antenna assembly to the other station;
- transmitting a second signal from the second antenna assembly to the other station, the second signal comprising the first signal time shifted by a delay of known duration;
- receiving the first and second signals at the other station;
- and
- decoding the first and second signals at the other station.
A communication system, comprising:
- a base station comprising a first antenna assembly having plural radiating elements and a second antenna assembly having plural radiating elements, the base station being operable:
- to transmit a first signal from the first antenna assembly;
- to transmit a second signal from the second antenna assembly, the second signal comprising the first signal time shifted by a delay of known duration;
- and
- at least one other station operable:
- to receive the first and second signals;
- and
- to decode the first and second signals.
A method of operating a base station, comprising:
- receiving a signal transmitted from another station to the base station at a first antenna assembly and a second antenna assembly;
- determining a power of the signal received at the first antenna assembly relative to a power of the signal received at the second antenna assembly;
- and
- setting a first power for transmission from the first antenna assembly and a second power for transmission from the second antenna assembly in response to the power of the signal received at the first antenna assembly relative to the power received at the second antenna assembly.
A base station, comprising:
- a receiver operable to receive at a first antenna assembly and a second antenna assembly a signal transmitted from another station to the base station;
- a processor operable:
- to determine a power of the signal received at the first antenna assembly relative to a power of the signal received at the second antenna assembly;
- and
- to set a first power for transmission from the first antenna assembly and a second power for transmission from the second antenna assembly in response to the power of the signal received at the first antenna assembly relative to the power received at the second antenna assembly.
