Patent Date Description6757319 6/29/2004 “Closed loop power control for common downlink transport channels”

To increase capacity in a spread spectrum packet communication system, a closed loop power control (CLPC) is provided for a common/shared downlink transport channel, such as a Forward Access Channel (FACH) and Downlink Shared Channel (DSCH), by using an existing uplink Common Packet Channel (CPCH) mechanism. After an appropriate access phase and a collision detection phase, a mobile station sends its closed-loop power control information along with any packet data over the CPCH uplink channel. Concurrently, the base station (BS) begins its downlink transmission of data and control information to the mobile station (MS). The base station transmits the packet data through the common/shared downlink transport channel, and the power of that transmission is controlled in response to the control information sent by the MS. The power of the uplink transmission from the MS is controlled in response to the control

The base station broadcasts status information as to the availability and/or available data rates for each common packet channel (CPCH) or group of CPCH channels. Each mobile station uses the status information to select an available channel and/or a channel with sufficient data rate.

station transmits the preambles at increasing power levels. When the base station detects a preamble transmission, the base station responds with a corresponding acknowledgment. Upon receiving this acknowledgment, the mobile station preferably selects a collision detection (CD) signature and transmits a CD preamble containing that signature. If the base station receives more that one CD preamble, it selects one and responds by sending back a corresponding CD acknowledgement. In response, the mobile station begins to send its packet data along with any closed-loop power control information over the selected CPCH channel. If the MS detects a loss of the downlink channel, the MS halts its CPCH uplink transmission. Also, during a transmission of data, the mobile station that has successfully obtained access can piggy-back data packets one after another so long as it has packets ready to send, up to a maximum limit set by the network.

Patent Date Description6507601 1/14/2003 “Collision avoidance”

A code-division-multiple-access (CDMA) system provides a collision avoidance mechanism for packet communications. When mobile stations attempt to establish links with a base station, the base station selects one mobile station to transmit data over an intended uplink channel. The base station transmits a predetermined sequence, during the first frame of the data transmission over the downlink control channel that corresponds to the intended uplink channel. If several mobile stations detect or mis-perceive successful access attempts, those stations begin data transmissions via respective desired uplink channels. At the same time, the mobile stations listen for the known sequence over the various corresponding downlink channels. Upon successful detection of the known sequence, one mobile station continues transmission of its data over the intended channel. However, any contending mobile station that does not detect the known sequence on the appropriate downlink channel immediately stops its data transmission.

spread-spectrum modulation, mobile stations initially seek access to a selected one of two or more groups of common packet channels (CPCHs) serviced through a base station. A second order collision resolution phase, conducted between the base stations and contending mobile stations, serves to allocate one or more available channels from the selected group of channels among the contending mobile stations. In the collision resolution phase, each mobile station randomly selects a collision detection (CD) signature and sends that signature in a CD preamble. For each available channel in the group, the base station assigns one of the mobile stations. For each assigned mobile station, the base station transmits a CD acknowledgement that corresponds to the CD preamble of the assigned mobile station and identifies the available channel assigned to that mobile station.

In a cellular spread-spectrum communications network, a system and method for handing off a remote station from a source-base station to a target-base station without loss of data. The remote station receives a first spread-spectrum signal having a first signal quality from the source-base station and transmits data to the source-base station at a first data rate and a first power level. Responsive to monitoring the first signal quality and comparing the first signal quality to a plurality of signal qualities of a respective plurality of received-spread-spectrum signals, the remote station initiates handoff when any of a number of predetermined criteria are met. Upon initiating handoff to the target-base station, the remote station stores the data that would otherwise have been transmitted. Once handoff is complete, the remote station transmits the stored data to the target-base station at a second data rate and a second power level, with the second data rate greater than the first data rate and the second power level greater than the first power level. Once the stored data has been transmitted, the remote station transmits data to the target-base station at a data rate and power level comparable to the first data rate and the first power level.

The broadcast common-synchronization channel has a common chip-sequence signal, which is common to the plurality of remote stations. In response to the RS-spread-spectrum receiver receiving the broadcast common-synchronization channel, and determining frame timing from the frame-timing signal, an RS-spread-spectrum transmitter transmits an access-burst signal. The BS-spread-spectrum transmitter, responsive to the BS-spread-spectrum receiver receiving the access-burst signal, transmits an acknowledgment signal. In response to the first RS-spread-spectrum receiver receiving the acknowledgment signal, the first RS-spread-spectrum transmitter transmits a spread-spectrum signal having data.

Publications

30 technical papers in the wireless field. Originator and co-inventor of the Common Packet Channel Technology (CPCH) concept.

CPCH is part of the 3rd generation global standard called 3GPP. Developed and taught short industry courses in wireless communications. More than 30 marketing presentations and technical tutorials on UMTS in the past two years.
