Abstract: A method to satisfy a delay requirement for a delay sensitive data connection through a scheduling, the method comprising: setting a discard timer for the delay sensitive data connection; determining an age of a packet corresponding to the delay sensitive service in a priority queue; performing a comparison between the age of a most recently successfully transmitted or time expired data packet with the discard timer setting, to determine whether the age of the compared packet is less than the discard timer setting by a predetermined margin; and calculating a new delay factor for the delay sensitive data connection based on the comparison and an old delay factor of the delay sensitive data connection. Aspects of the invention include the calculating step further comprising setting the new delay factor to a value obtained by increasing the old delay factor by a first predetermined factor and dropping the oldest packet if the age of the oldest packet is not less than the discard timer by a predetermined margin.

Abstract: A method to provide a nominal best effort data rate based on a Quality of Service (QoS) requirement of a user data connection, the method comprising assigning ( 105 ) a service priority based on the QoS requirement, and assigning ( 110 ) the nominal best effort data rate for the service priority using a predetermined function. Further, it comprises of a method to determine a scheduling priority value for a user data connection by providing a relative fairness. Furthermore, the method comprises a method to satisfy a delay requirement for a delay sensitive data connection through a scheduling.

Abstract: To address the need for a resource allocation scheme that results in a better tradeoff between cell-edge performance and overall spectral efficiency, a communication system (100) is provided that allocates uplink transmit power to user equipment (UEs) (102, 104) based on a fractional power control scheme (300). In another embodiment, since the cell-edge users are also likely to be power limited, the communication system may implement a minimized uplink transmission bandwidth resource allocation scheme (404, 406, 408, 410, 412, 414) that may work with the fractional power control scheme to achieve a level of performance desired for uplink transmissions in 3GPP (Third Generation Partnership Project) and 3GPP2 Evolution communication systems.

Abstract: A communication system provides downlink acknowledgments corresponding to uplink transmission using hybrid automatic repeat request to multiple users in an Orthogonal Frequency Division Multiplexing communication system, wherein a frequency bandwidth comprises multiple frequency sub-carriers, by spreading each acknowledgment of multiple acknowledgments with a selected spreading sequence of multiple spreading sequences to produce multiple spread acknowledgments, wherein each acknowledgment is intended for a different user of the multiple users, and distributing the multiple spread acknowledgments across the multiple frequency sub-carriers.

Abstract: Various gain factors for pilot information are used to determine a corresponding plurality of likely channel performance values for a plurality of data channels (and/or services). The resultant information is used to select a specific gain factor to apply when transmitting the pilot information. In one embodiment, the gain factor that correlates to the highest signal to interference plus noise ratio is used.
