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.

摘要： A wireless network includes a base station which can serve terminals directly, or via multi-hop transmission paths via relay stations. The base station transmits a downlink sub-frame which includes a first set of frame control information and a second set of frame control information. The second set of frame control information occupies a different position within the downlink sub-frame compared to the first set of frame control information. A relay station is able to transmit a downlink sub-frame to a terminal, or another relay station, while still being able to receive a set of frame control at a different time during the downlink sub-frame. The invention is especially useful in a wireless network in which the downlink transmissions of a base station and a relay station are synchronised to one another and where the downlink transmissions of a base station and relay station occupy the same, or similar, frequency bearer.

摘要： The present invention provides a scheduler capable of maximizing aggregate throughput while achieving controlled amount of fairness among users and meeting Quality of Service (QoS) requirements. The scheduler is configured to select the next unit of data to transmit from multiple queues associated with access terminals waiting to receive the data. For each access terminal, a weighting factor is calculated based on a temporal fading factor, a throughput fairness factor, and a delay QoS factor. The unit selected for transmission corresponds to the access terminal having the greatest overall weighting factor. The process repeats for each unit being transmitted.

摘要： The present invention provides an access point, such as a base station, facilitating wireless communications with a plurality of mobile terminals, which are capable of operating in an active or standby mode. The access point provides active-to-standby transition timers for controlling when to instruct active mobile terminals to enter a standby mode after the end of a communication session. The active-to-standby transition timers have variable values based on one or more Quality of Service (QoS) parameters. Different mobile terminals may be associated with different QoS levels. The values for the active-to-standby transition timers may vary based on their respective QoS levels. The initial values for the active-to-standby transition timers may differ depending on the QoS level for the associated mobile terminal. As the QoS parameters indicate conditions adversely affecting QoS, the active-to-standby timer values may decrease in proportion to the QoS parameters.
摘要翻译：本发明提供了一种接入点，诸如基站，便于与多个移动终端进行无线通信，这些移动终端能够以主动或待机模式运行。接入点提供主动到待机的转换定时器，用于在通信会话结束之后控制何时指示活动移动终端进入待机模式。主动到待机转换定时器具有基于一个或多个服务质量（QoS）参数的可变值。不同的移动终端可能与不同的QoS级别相关联。主动到待机转换定时器的值可能会根据各自的QoS级别而变化。主动到待机转换定时器的初始值可能会因相关移动终端的QoS级别而异。由于QoS参数表示对QoS有不利影响的情况，主动到待机定时器值可能与QoS参数成比例地减小。

摘要： Security in wireless communication networks that employ relay stations to facilitate communications between base stations and mobile stations is enhanced. In one embodiment, resource information provided to one or more relay stations from a base station or another relay station is encrypted prior to being delivered to the one or more relay stations. Only authorized relay stations are allocated an appropriate key necessary to decrypt the resource information. As such, only appropriate relay stations are able to access and use the resource information to effect communications directly or indirectly between the base stations and the mobile stations. In certain embodiments, the resource information is delivered between the various base and relay stations using either unicast or multicast delivery techniques.

摘要： The present invention provides conversion between SDUs transmitted between a central network controller and base stations and PDUs transmitted between the base stations and mobile terminals. For downlink communications, SDUs are transmitted from the central network controller and forwarded to the base stations in an active set. One base station will break down the SDUs to create PDUs to transmit to the mobile terminal. For uplink communications, the base station will receive PDUs from the mobile terminal, create SDUs from the PDUs, and transmit the SDUs to the central network controller. During switching events, continuity information received from a previously serving base station is processed by the mobile terminal and used to create continuity information to send to the currently serving base station and used to determine the appropriate PDU from which to start transmissions to the mobile terminal after the switching event.
摘要翻译：本发明提供了在中央网络控制器和基站之间传输的SDU与在基站和移动终端之间传输的PDU之间的转换。对于下行链路通信，SDU从中央网络控制器发送并转发到活动集中的基站。一个基站将分解SDU以创建PDU以向移动终端传输。对于上行链路通信，基站将从移动终端接收PDU，从PDU创建SDU，并将SDU发送到中央网络控制器。在切换事件期间，由先前服务的基站接收的连续性信息由移动终端处理，并用于创建连续性信息以发送到当前服务的基站，并且用于确定适当的PDU，从而在其之后开始传输到移动终端切换事件。
