摘要： Methods and apparatus are described for enabling downlink transparent relay in a wireless communication network. In a wireless communications network, a base station and a mobile station may communicate with each other via a relay station, as needed. Transparent relay may allow for relay communication between a base station and a mobile station although the mobile station is unaware of the relay station. However, non-contiguous transmission of a relay station may lead to channel quality measurement and channel estimation degradation during downlink transparent relay. According to some aspects, a base station may schedule a mobile station to a transmission mode that utilizes dedicated pilot signals for downlink transparent relay, and a relay station may transmit data and dedicated pilot signals over the same channel resources as the base station. According to some aspects, the relay station may null common pilot signals transmitted by the base station.

摘要： A wireless network includes a base station and a relay station for extending wireless coverage of the base station. Downlink data is sent by the base station and relayed through the relay station to a mobile station, where the downlink data is associated with a preamble that is sent directly from the base station to the mobile station. A transmit power of the relay station is adjusted for transmitting the downlink data from the relay station to the mobile station to reduce a difference between a first power level of the preamble received at the mobile station and a second power level of the downlink data received at the mobile station. The uplink transmit power of the mobile station tfor the data sent to the relay station is adjusted to compensate for the difference in path loss from mobile station to base station and mobile station to relay station and to compensate for the difference in noise _plus_interference level at relay station compared to that of the base station.

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： 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： HARQ methods and systems and systems are provided which adaptively switch between two modes such as an NCP (non-complete puncture) mode, and a SAW (stop and wait) mode. Advantageously, this is done to avoid buffer overflow associated with ongoing NCP, and the delay associated with SAW. The switch between the modes can be performed on the basis of any number of criteria. These may include buffer size, consecutive negative acknowledgements in respect of either of the modes, length of time in one or the other mode, to name a few examples.

摘要： A wireless system has a high rate data channel (F-PDCH) for time multiplexed communications to multiple mobile stations (MSs). Control channels include a forward link common power control channel (F-CPCCH) and reverse link feedback channels for pilot (R-PICH), forward channel quality (R-CQICH),and data acknowledgements (R-ACKCH) from each MS. An MS can have an active state for data communications, for which these control channels are used at the full (time slot) rate, or a control hold state, in which acknowledgements are not needed and the others of these control channels can be shared among a plurality of MSs in the control hold state and each using a reduced rate such as 1/2, 1/4, or 1/8 of the full rate. The arrangement can support an increased number of active MSs, factilitating an increased total throughput on the high rate data channel, without increasing system resources for the control channels.

摘要： A wireless communications system includes a shared TDM data channel for communications in different time slots with respective mobile stations (MSs), as well as dedicated channels. A first medium access control (MAC) multiplexing sublayer, provided in a base station controller, maps information of logical channels for communications services to the communications channels. A second MAC multiplexing sublayer maps information, mapped to the shared data channel in the first MAC multiplexing sublayer, to respective data units for communication in respective TDM time slots of the shared channel. The second MAC multiplexing sublayer handles scheduling, adaptive modulation and coding, and automatic retransmission of information on the shared data channel, as well as shared control channels for the shared data channel and channel quality feedback and data acknowledgement channels from the MSs.
