Patent number: 7486639Abstract: An adaptive time division duplexing (ATDD) method and apparatus for duplexing transmissions on a communication link in wireless communication systems. Communication link efficient is enhanced by dynamically adapting to the uplink and downlink bandwidth requirements of the communication channels. Time slots are flexibly and dynamically allocated for uplink or downlink transmissions depending upon the bandwidth needs of a channel. Communication link bandwidth requirements are continuously monitored using sets of predetermined bandwidth requirement parameters. Communication channels are configured to have either symmetric or asymmetric uplink/downlink bandwidths depending upon the needs of the channel. Channel bandwidth asymmetry can be configured alternatively in favor of the uplink transmissions (i.e., more time slots are allocated for uplink transmissions than for downlink transmissions) or in favor of the downlink transmissions (i.e.Type: GrantFiled: April 26, 2005Date of Patent: February 3, 2009Assignee: Cisco Technology, Inc.Inventors: Kenneth L.

Publication number: 20050058098Abstract: A method of assigning downlink time slots to receive units where the units may generate data using different modulation schemes. The method preferably assigns the downlink time slots as a function of the complexity of modulation schemes employed by the units. Further, the method preferably assigns the time slots from the least complex modulation scheme to the most complex scheme. The method may further assign uplink time slots to transmit units where the transmit units may generate data using different modulation schemes. The method preferably assigns the uplink time slots as a function of the complexity of modulation schemes employed by the uplink units. Further, the method preferably assigns the uplink time slots from the least complex modulation scheme to the most complex scheme. In other embodiments, the downlink time slots are assigned as a function of the bit per symbol rate employed by the receive units, preferably from the lowest bit per symbol rate to the highest bit per symbol rate.Type: ApplicationFiled: October 12, 2004Publication date: March 17, 2005Inventors: Israel Klein, Kenneth Stanwood, Steve Pollmann, Frederick Price, Rami Hadar, Eli Arviv, David Gazelle, Sheldon Gilbert

Patent number: 6707798Abstract: The present invention is a method and apparatus for reducing co-channel interference. The present invention includes a powerful means for eliminating co-channel interference from base stations in a wireless communication system. The present co-channel interference reducing method and apparatus utilizes frame synchronization between selected time frames (e.g., odd and even time frames) to reduce co-channel interference. Advantageously, the present invention reduces co-channel interference and, thus, allows robust modulation schemes to operate even at worst case line-of-sight (LoS) interference scenarios of 100%. The present invention can also use an uplink/downlink ratio formula to further improve system capacity (i.e., reduce co-channel interference) in ATDD systems. The present inventive method and apparatus can be used in any type of frame based and frame synchronized communication system.Type: GrantFiled: March 31, 2000Date of Patent: March 16, 2004Assignee: Ensemble CommunicationsInventors: Israel Jay Klein, Sheldon L.

Patent number: 6097704Abstract: In a wireless communication system in which a base station communicates with plural mobile stations using frames of digital data, each frame having a control slot and plural voice (or data) slots, the present invention divides at least some of the slots into two portions and receives communications from one of the mobile stations during a first portion of a voice slot and communicates with the same mobile station during the second portion of the same slot.Type: GrantFiled: June 28, 1996Date of Patent: August 1, 2000Assignees: Harris Corporation, CTP Systems, Ltd.Inventors: Allen Jackson, David Hochman, Parminder Sikand, Rami Hadar, Jay Klein, Shmuel Arditi, Shmuel Bachinski

Patent number: 6023460Abstract: In a wireless communication system in which a base station communicates with plural mobile stations using a control channel and plural voice (or data) channels, the present invention uses the control channel as a voice channel whenever the other voice channels are in use and a request is received from a mobile station for another voice channel. The base station's use of the control channel varies as the control channel switches from a control channel to a voice channel and back to a control channel again.Type: GrantFiled: June 28, 1996Date of Patent: February 8, 2000Assignees: Harris Corporation, CTP Systems, Ltd.Inventors: Allen Jackson, David Hochman, Parminder Sikand, Rami Hadar, Jay Klein, Shmuel Arditi, Shmuel Bachinski

Patent number: 6023621Abstract: In a wireless communication system in which plural base stations communicate with plural mobile stations using a control slot and plural voice (or data) slots, the present invention dynamically allocates which of a predetermined set of frequencies are used by a given base station at a given time. The base stations monitor the predetermined set of frequencies to determine which frequencies are being used within which slots within the range of radio reception of the base station. Currently unused frequency/slot combinations are assigned by a base station to service the next request for a voice slot.Type: GrantFiled: June 28, 1996Date of Patent: February 8, 2000Assignees: Harris Corporation, CTP Systems, Ltd.Inventors: Allen Jackson, David Hochman, Parminder Sikand, Rami Hadar, Jay Klein, Shmuel Arditi, Shmuel Bachinski

Patent number: 5995492Abstract: A digital communication system, which may be a Time Domain Multiple Access system, is operated with plural antenna to reduce the problems associated with fading, interference and multipath in signals received from mobile, wireless units. The protocol used between the fixed station and the mobile, wireless units provides an opportunity for the fixed station to evaluate the signal received from the wireless unit and to transmit to the wireless unit using the antenna judged to have the best received signal.Type: GrantFiled: June 28, 1996Date of Patent: November 30, 1999Assignee: CTP Systems, Ltd.Inventors: Jay Klein, Rami Hadar, Shmuel Arditi, Ilan Barak

Patent number: 5978674Abstract: A system and method for readily varying the configuration of a telephone system and the functions/features available to the users of wireless telephone instruments on the system. The telephone instruments may include a display which can be configured by interaction with a base station to vary the interpretation given to inputs received from the user. Features available to the user of a particular telephone instrument may be specifically adapted to the user and may be readily modified as the user changes, as the user's authorization changes, and/or as the telephone system's capabilities are changed.Type: GrantFiled: June 28, 1996Date of Patent: November 2, 1999Assignees: Harris Corporation, CTP Systems, Ltd.Inventors: Allen Jackson, David Hochman, Parminder Sikand, Daniel Terhune, Keith Neuendorff, Rami Hadar, Shmuel Bachinski, Jay Klein, Shmuel Arditi, David Meshu
