Patent number: 6208858Abstract: A method for reducing call dropping rates in a multi-beam communication system. The multi-beam communication system includes a user terminal, a gateway, and a plurality of beam sources, where each beam source projects a plurality of beams, and where a communication link between the user terminal and the gateway is established on one or more beams. The method according to the present invention relies on a messaging protocol between the gateway and the user terminal. Based on messages sent from the user terminal to the gateway, preferably on a preselected periodic basis, the gateway can determine the more desirable beam(s) for transmitting data or information to the user terminal. The messages sent from the user terminal to the gateway contain values representing beam strengths as measured at the user terminal. The gateway uses the user terminal measured beam strengths to select the beams that should be used for transmitting data or information to the user terminal.Type: GrantFiled: July 21, 1998Date of Patent: March 27, 2001Assignee: Qualcomm IncorporatedInventors: Franklin P.

Patent number: 5917812Abstract: A system and method for reducing radio frequency interference arising in connection with pulsed transmission over time division multiplexed communication channels. In a first embodiment, a subscriber station is nominally assigned all of the slots of each frame of a first transmit channel. By transmitting RF energy substantially continuously, the subscriber station reduces interference arising from pulsed transmission. In a second embodiment, a subscriber station is nominally assigned one or more slots of each frame of a primary channel for conventional transmission of useful information, and is also instructed to continuously transmit RF energy over an auxiliary channel at times other than during the assigned primary channel slots. In this way, interference generated in the vicinity of the subscriber station is reduced due to the substantially continuous transmission of RF energy by the subscriber station.Type: GrantFiled: April 16, 1996Date of Patent: June 29, 1999Assignee: Qualcomm IncorporatedInventors: Franklin P.
