摘要： The present invention provides for a scheduling data for transmission by an access point, such as a base station. The scheduling provides adaptive fairness control, which depends on how close the users are to a minimum data rate requirement. If desired, more emphasis can be placed on fairness when there are users close to the minimum data rate requirement and more emphasis on maximizing throughput when all of the users are far from the required minimum data rate. Scheduling can also guarantee a maximum trop rate for delay-sensitive data, assuming sufficient resources are available, as well as guarantee a minimum data transfer rate for all users by ensuring that users below their minimum requirement have a higher priority than users that exceed their minimum requirement have a higher priority than users that exceed their minimum requirement. If there are not enough resources to satisfy each user's minimum data rate due to a failure of the call admission process, then the variance in throughput can be minimized for each class of users. The scheduling can also optimize scheduling parameters for multi-carrier systems by using the number of carriers to determine scheduling parameters for the delay-senstive users in order to maximize throughput.
摘要翻译：本发明提供了用于由诸如基站的接入点进行传输的调度数据。调度提供了适应性公平控制，这取决于用户对最低数据速率要求的接近程度。如果需要，当用户接近最低数据速率要求时，可以更加强调公平性，并且当所有用户远离所需的最低数据速率时，更重视最大化吞吐量。假设有足够的资源可用，调度还可以确保延迟敏感数据的最大速率，并且通过确保低于其最低要求的用户具有比超过最小要求的用户更高的优先级来保证所有用户的最小数据传输速率。要求比超过最低要求的用户要优先。如果由于呼叫许可过程失败而没有足够的资源来满足每个用户的最小数据速率，则可以使每类用户的吞吐量方差最小化。调度还可以通过使用载波数量来确定延迟用户的调度参数来优化多载波系统的调度参数，以便最大化吞吐量。

摘要： International Mobile Telecommunications (IMT) Advanced technology, also known as 4th Generation (4G) targets to support up to 100 MHz BW. LTE currently supports single carrier bandwidths of up to 20 MHz. The present application describes a multi-carrier approach in which some embodiments of the invention provide a simple solution of aggregating multiple single carrier bandwidths to obtain a wider bandwidth (> 20 MHz). Such an approach may extend Long Term Evolution (LTE) bandwidth to greater than that provided by a single carrier, yet maintain full backward compatibility with technologies that predate 4G technology and utilize smaller, single carrier bandwidths. More generally, embodiments of the invention can apply to other communication standards than only LTE.

摘要： A method selects a path for forwarding a data packet in a wireless communication system. A system capacity versus delay impact curve is calculated for a direct path to mobile station. The direct path has a capacity cost based on communication quality of a direct link between a base station and the mobile station. This curve is shifted by a predetermined time corresponding to an additional delay over a relay path to produce a projected capacity curve for the relay path having a second capacity cost determined according to a combined measure of signal quality of multiple links in the relay path. The second capacity cost is multiplied by a capacity cost ratio to produce a relay capacity curve. The direct path or the relay path is selected based on a comparison of the system capacity versus delay impact curve and the relay capacity curve according to a QoS requirement.

摘要： One or more relay stations may be employed along a wireless communication access path between an ingress station and an egress station. A logical communication tunnel is established between the ingress and egress stations through any number of intermediate relay stations to handle session flows of PDUs. As PDUs arrive, the ingress station may determine and add scheduling information to the PDUs before they are delivered to the downstream intermediate relay stations or egress stations. The scheduling information is used by the downstream stations to schedule the PDUs for further delivery. The scheduling information may also be used by the egress station to schedule the PDUs for delivery. The scheduling information added to the PDU by the ingress station bears on a QoS class associated with the PDU, a deadline for the egress station to deliver the PDU, or a combination thereof.
