摘要： A method for setting optimal phase settings for a plurality of antenna elements of a subscriber unit in a CDMA cellular telephone system includes the steps of detecting a received pilot signal at each of the plurality of antenna elements, combining the received pilot signal detected at each of the plurality of antenna elements with a summation circuit to produce a combined received pilot signal, determining a quality metric for the combined received pilot signal and adjusting phase settings of at least one of the plurality of antenna elements on the subscriber unit in response to the quality metric of the received pilot signal. These steps are repeated until the determined quality metric of the combined received pilot signal reaches a maximum.

摘要： An antenna apparatus which can increase capacity in a cellular communication system. The antenna operates in conjunction with a mobile subscriber unit and provides a plurality of antenna elements, each coupled to a respective programmable phase shifter. The phase of each antenna element is programmed for optimum reception during, for example, an idle mode which receives a pilot signal. The antenna array creates a beamformer for signals to be transmitted from the mobile subscriber unit, and a directional receiving array to more optimally detect and receive signals transmitted from the base station. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference. Various techniques for determining the proper phase of each antenna element are accommodated.

摘要： In a wireless communication system, there are several wireless channels used for communication between users and a base station. Channel characteristics may be defined by whether a channel is carrying traffic data and the timing of the channel transmissions with respect to channels not carrying traffic data. Different power levels between channels carrying traffic data or not may be defined and individual power levels of each channel may be amended based on individual power level command responses.

摘要： A transmitter/receiver system for high data transfer in a wireless communication system includes a physical layer processor that comprises an FEC coder, a demultiplexer and a plurality of modem processors. The FEC coder applies error correction codes to the high data rate signal. Thereafter, the demultiplexer distributes portions of the coded high data rate signal to the modem processors. Each modem processor processes its respective portion of the coded signal for transmission in an independent channel.

摘要： A subscriber access unit includes a transceiver for providing wireless communication of digital signals. The digital signals are communicated to a base station using at least one radio frequency (RF) channel via Code Division Multiple Access (CDMA) modulated radio signals defined by orthogonal codes. Orthogonal subchannels are made available by the base station within each CDMA RF channel. A bandwidth manager is connected to the transceiver, and when the transceiver is actively sending data, at least one orthogonal subchannel is allocated by the base station on an as-needed basis. The number of orthogonal subchannels being allocated changes during a given session. The transceiver, when powered on but not actively sending data, provides an idling mode connection on a reverse link. The idling mode connection is based on an orthogonal subchannel shared with at least one other subscriber access unit, but utilizes different time slots of the shared orthogonal subchannel.

摘要： A repeater environment is provided to deploy a feedback cancellation loop that is adaptively coupled with an antenna array such that a selected metric can be derived by deploying a one or more of selected metrics (e.g., composite metrics) 5 comprising a selected filter bank operative to process the signal on a bin by bin basis and the derived metric can be applied to the antenna array and feedback cancellation loop combination to improve signal integrity and amplification, beam forming operations, and pilot control and overhead channel control operations. In an illustrative implementation, an exemplary repeater environment comprises, a 10 transmitter, a receiver, an equalized feedback cancellation loop circuitry comprising a filter bank, the cancellation loop being operatively coupled to an antenna array. In the illustrative implementation, the feedback cancellation loop can receive signals as input from a cooperating antenna array and provide output signals such as a feedback leakage signal to a cooperating.

摘要： In an illustrative embodiment of the present invention, a reference signal including pilot information is transmitted from a base station to one or multiple field units over a pilot channel. A message is also sent to the field units over a paging channel to indicate an effective radiated power level at which the reference signal is transmitted on the pilot channel. Based on a received power level of the reference signal at a field unit and the effective radiated power level of the reference signal, a forward path loss is estimated at the field unit for the forward link between the base station and field unit. Assuming the path loss in the reverse link is approximately the same as the estimated forward link path loss, the field unit can transmit, a reply message in the reverse link so that the base station generally receives a message at a desired power level.

摘要： A method and apparatus are used to support the transmission of data to a user over multiple allocated data channels. Data packets are transmitted in time-slots of the allocated data channels to corresponding target receivers without the need for explicitly assigning particular time-slots to a target user well in advance of transmitting any data packets in the time-slots. Instead, each data packet transmitted in a time-slot includes a header label or preamble indicating to which of multiple possible receivers a data packet is directed. The preamble also preferably includes decoding information indicating how a corresponding data payload of the data packet is to be processed for recapturing transmitted raw data.
