Patent number: 7643423Abstract: Dynamic allocation of communication channels among communication units (CU) in a communications system. Dynamic channel allocation employs a reservation set for reserving channels and an allocation set corresponding to the reservation set for receiving allocated channels. The reservation set and the allocation set are changed dynamically as a function of network parameters to control the dynamic channel operation. Reservation set information is broadcast downlink to multiple users to reserve an allocation set of uplink radio resources for specific ones of the users. The system uses a modification of the packet data channel (PDCH) of a GPRS/EGPRS or EDGE system which employs an Uplink Status Flag (USF) on each PDCH downlink radio block. The downlink reservation set information is commonly received by all users in the group of users. Allocation delay, bandwidth efficiency and other system parameters are optimized.Type: GrantFiled: August 21, 2006Date of Patent: January 5, 2010Inventors: Gopal Chillariga, Rohit Kaushal, Bhupal Kanaiyalal Dharia, Lance Kazumi Uyehara, Gerhard Albert Koepf, Kevin Dean Raack, Ujjal Kumar Ghoshtagore

Patent number: 7613463Abstract: Fast macrodiversity switching (FMS) dynamically switches radio links used for traffic and control channels for a mobile station among a number of base transceiver stations (BTS) without changing the radio resource, that is, using the same frequency and time slot combination (TDMA) or frequency and spreading code combination (CDMA). The traffic channel switching is under control of zone managers. Each BTS includes a zone manager where a host BTS has its zone manager designated as a host zone manager and other BTSs (assistant BTSs) have their zone managers designated as assistant zone managers. The control by the host and assistant zone managers includes switching down-link signals to and up-link signals from mobile stations among base transceiver stations which include broadcast channels (non-switched) and dedicated (switched) channels. Measurements of the wireless signals are made at macrodiverse locations.Type: GrantFiled: October 3, 2008Date of Patent: November 3, 2009Inventors: Bhupal Kanaiyalal Dharia, Gopal Chillariga, Ujjal Kumar Ghoshtagore, Rohit Kaushal, Gerhard Albert Koepf, Lance Kazumi Uyehara

Patent number: 7551595Abstract: Fast macrodiversity switching (FMS) of channels that employ interleaving. The fast macrodiversity switching dynamically switches radio links used for traffic and control channels for a mobile station among a number of base transceiver stations (BTS) without switching the radio resource, using the same frequency and time slot combination (TDMA) in an environment where interleaving is occurring. The fast macrodiversity switching of channels and interleave processing is under control of an interleave manager which is distributed among zone managers. The control by the host and assistant zone managers includes switching down-link signals to and up-link signals from mobile stations among base transceiver stations which include broadcast channels (non-switched) and dedicated (switched) channels that employ interleaving. The dedicated channels are switched as frequently as a signal switch time which can be the frame rate of the up-link signals.Type: GrantFiled: August 31, 2006Date of Patent: June 23, 2009Assignee: Northstar Acquisitions, LLCInventors: Bhupal Kanaiyalal Dharia, Gopal Chillariga, Ujjal Kumar Ghoshtagore, Rohit Kaushal, Gerhard Albert Koepf, Lance Kazumi Uyehara
