Abstract: In some aspects, each cell in the communications system can be designed to operate in accordance with a set of back-off factors that identify the reductions in peak transmit power levels for the channels associated with the back-off factors. The back-off factors are defined to provide the required power to a large percentage of the users while reducing the amount of interference. In some other aspects, the cells operate using an adaptive reuse scheme that allows the cells to efficiently allocate and reallocate the system resources to reflect changes in the system. A reuse scheme is initially defined and resources are allocated to the cells. During operation, changes in the operating conditions of the system are detected and the reuse scheme is redefined as necessary based on the detected changes. For example, the loading conditions of the cells can be detected, and the resources can be reallocated and/or the reuse scheme can be redefined. In yet other aspects, techniques are provided to efficiency schedule data transmissions and to assign channels to users. Data transmissions can be scheduled based on user priorities, some fairness criteria, system requirements, and other factors. Users are assigned to available channels based on a number of channel assignment schemes. Channel metrics are also provided, which can be used to prioritize users and for channel assignments.

Abstract: A method and apparatus for wireless communications wherein a base station transmits a signal to sending data to a subscriber station through a signal beam that sweeps through the coverage area of the base station. User data addressed to the subscriber station is buffered until the signal beam angle of the signal beam allows efficient transmission. The base station may alter the beam sweep speed or the shape of the beam's radiation pattern over time to maximize system efficiency and capacity.

Abstract: A method (100) for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) is calculated as a function of packet delay time of the user. When a given user has a packet delay time violating a threshold, the PF of the user is adjusted accordingly. In one embodiment, a delay function is applied to the PF calculation, wherein the delay function considers the average requested data rate for all users in the active set having pending data and the average data rate of a given user.

Abstract: Several methods and corresponding apparatus reduce peak to average power in signals transmitted in a wireless communications system, particularly with respect to pilot symbols transmitted from a base station to several user stations. A large peak to average amplitude of inserted pilot symbols has been found to result from a common sign chip position that exists in orthogonal codes, such as Walsh codes. In a first embodiment, the Walsh codes are multiplied by a random value of +/- 1. Under a second embodiment, the common sign chip position is eliminated in each Walsh code. The user station then inserts the missing chip position to regain orthogonality. In a third embodiment, the base station transmits pilot symbols, on a separate pilot channel, in only symbol positions that user stations expect to find pilot symbols. Under a fourth embodiment, each Walsh code is randomly shifted.

Abstract: A method and apparatus for efficient candidate frequency search while initiating a handoff in a code division multiple access communication system. The method includes when the pilot signal is transmitted by the mobile station that is power controlled to a target receive level, the traffic channel power level is increased relative to the pilot channel to improve receiver performance. An improved feature is that the received pilot received at the base station stays the same while the receiver receives extra energy in the redundant traffic symbols received to enhance the probability of correctly decoding the received frame. The base station detects the absence of the mobile station transmitted signal from the frequency of interest. If the base station is aware of the starting time and duration of the absence, it can focus its detection during this predetermined time period. The performance can be improved if the absence of the signal is spread across two frames at the frame boundary.

Abstract: A method and apparatus for selecting a favored transmission slot for communicating non-voice data in conjunction with a voice-data communication. The slot, reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel, is selected based upon the transmission power levels for voice-data transmitted by a base station to a remote station on a fundamental channel. The favored transmission slot is selected without the remote station messaging information to the base station concerning frequency channel or interference information for the supplemental channel. A method of performing forward-link scheduling in a wireless communication system includes determining the available base station power at the beginning of a frame, predicting the required transmit power at the beginning of the frame for each supplemental channel, determining rates sustainable with the predicted transmit power, dividing by throughput over a recent window to obtain a supplemental channel priority index, and allowing the supplemental channel with the highest priority index to transmit over the next frame.
