摘要： A method and an apparatus provide for controlled access to a shared communication medium. Time slots on a forward channel include information regarding status useful for remote units to determine whether a reverse channel is available for seizure. Additionally, information along the forward channel provides guidance to the remote units to control attempts to seize the reverse channel. In one embodiment a remote unit divides a data package into a plurality of portions and attempts to seize the reverse channel using a single portion of the data package which corresponds to one time slot on the reverse channel. It then waits until it receives notification along the forward channel that the first data portion was successfully received before it attempts to send any of the remainder of its data in consecutive time slots on the reverse channel.

摘要： A conditional e-coupon distribution method distributes e-coupon predefined by sellers to mobile users only if the number of mobile users requesting such e-coupons equals or exceeds a threshold. The method receives a request to browse e-coupons from a mobile user. The method receives the location of the mobile user and determines a plurality of sellers local to the mobile electronic device and a plurality of corresponding e-coupons available from the local sellers. The method receives a request for a particular e-coupon from a seller and authorizes the provision of said e-coupon to the mobile user. At the end of a processing cycle, the mobile user receives the requested e-coupon if all conditions, such as a period of time and threshold, have been met. A computer-usable medium having computer-readable program code embodied therein allows for storage of the method.

摘要： A method and apparatus for a high-capacity cellular network by improved sectorization and interleaved channel assignment is presented. Data transmission over a cellular network is carried out by implementation of a sectorization scheme, called the Narrow-Beam Quad-sector Cell (NBQC) sectorization scheme, and the corresponding Interleaved Channel Assignments (ICA). The NBQC sectorization scheme calls for each cell of a cellular network to be divided into four sectors, with each sector covered by a 60 degree antenna. Use of the NBQC sectorization scheme allows for implementation of the corresponding ICA, in which assignment of transmission channels to each cell is based on a re-use factor of N=2. Accordingly, the interleaved channel assignments allow for the use of the transmission channels in cells which are adjacent in the cellular network.

摘要： A dynamic resource allocation method and apparatus for broadband services in a wireless communications system. The communications system can have a number of cells, each of which has multiple sectors. Each sector can contain a number of communications sites. Information is transmitted in time subframes scheduled to avoid interference between the sectors and cells, and different degrees of concurrent packet transmission can be scheduled for different classes of communications sites. The communications sites can be classified based on reception quality, such as by comparing their measured signal-to-interference ratio (SIR) with a SIR threshold.

摘要： The invention provides a system that implements an algorithm for integrated link adaptation and power control to achieve specified error rates and to improve an overall throughput for real-time applications in wireless packet networks. The system initially divides wireless terminals into groups according to their signal path gains. Afterwards, the system can periodically adapt transmissions (i.e., link adaptations) based on the required error rates, actual error statistics and average transmission power for each wireless terminal group. Furthermore, transmission power can be adjusted by an enhanced Kalman-filter method to ensure successful reception.

摘要： A method for improving the performance for a streaming service by link-adaptation and power-control in a wireless packet network such as an Enhanced General Packet Radio Services (EGPRS) cellular network is described. In particular, the effects of a combined link adaptation and power control scheme (referred to as an error-based scheme) for achieving a target error rate, which is non-zero but low enough so that limited retransmission and error concealment techniques are effective, is presented.
