US Patent 7310537, titled "Communication on multiple beams between stations," has the following details:

• Assignee: Integral Wireless Technologies LLC (Current Assignee) (Original Assignee: Nokia Inc)
• Inventors: Risto Wichman, Olav Tirkkonen, Rinat Kashaev
• Filing Date: 2003-08-13
• Issue Date: 2007-12-18
• Abstract: The patent describes a method and communication system for wireless communication between stations using multiple beams. The method involves including beam identity information into signals transmitted on multiple beams from a first station, a second station receiving these signals, identifying the beams based on the identity information, and then selecting at least one beam for transmission on the wireless interface between the stations. The system includes an antenna array providing distinguishable multiple beams, a controller for identifying beams, and means for selecting beams based on the identified beam information. A station configured for this communication includes antenna means for receiving signals on multiple beams and a controller for identifying beams based on associated beam identity information.

Plain-Language Overview of Independent Claims:

• Independent Claim 1 (Method): This claim describes a method for two stations to communicate wirelessly using multiple beams. The first station sends signals on various beams, and each beam's signal includes unique "beam identity information." The second station receives these signals and uses this identity information to figure out which beams it received signals through. Crucially, the method then involves selecting one or more beams for future communication between the stations, specifically choosing a group of beams that are "geometrically distinguished" from each other.

• Independent Claim 20 (Communication System): This claim outlines a communication system designed to enable two stations to communicate wirelessly using multiple beams. The system includes an antenna array at the first station that generates multiple beams, where each beam can be uniquely identified by "beam identity information." It also has a controller that identifies the beams from which the second station received signals, based on this identity information. Finally, a "selecting unit" chooses at least one beam for transmission between the stations, specifically selecting a set of beams that are "geometrically distinguished" from each other.

• Independent Claim 26 (Station): This claim describes a station (either the first or second station in the communication) that includes an antenna unit to receive signals transmitted from another station on multiple beams. It also has a controller that identifies these beams based on the "beam identity information" associated with the received signals. The claim specifies that a set of "geometrically distinguished" beams is then selected for signal transmission between the two stations, based on the identified beam information.

• Independent Claim 29 (Apparatus): This claim is substantially similar to Claim 20, describing an apparatus (likely at the first station) that includes an antenna array providing multiple beams with identity information. It also has a controller for identifying received beams based on this information and a selecting means for choosing at least one beam for transmission, with the selection specifically involving a set of geometrically distinguished beams.

• Independent Claim 30 (Station): This claim is substantially similar to Claim 26, describing a station with antenna means for receiving multiple beams and a controller for identifying beams based on identity information. It further specifies that a set of geometrically distinguished beams is selected for transmission based on this identified beam information.
