摘要： The present invention provides a method of scheduling guaranteed bit rate and/or maximum bit rate applications. Embodiments of the method may include setting, for a mobile node during a time interval, a first weight equal to a sum of a previous first weight associated with the mobile node during a previous time interval and a correction factor that is a linear function of a difference between a first bit rate and an indication of a throughput of the mobile node. Embodiments of the method may also include scheduling communication with the mobile node based on the first weight.

摘要： A system and method for cooperative spectrum sensing in cognitive radio (CR) systems is provided. A method for CR user operation includes coordinating with partner CR users to share spectrum sensing information, combining spectrum sensing information from partner CR users, and determining if a transmission opportunity exists based on the combined spectrum sensing information. The method also includes transmitting a message to a CR user if the transmission opportunity exists, and storing the message if the transmission opportunity does not exist.

摘要： A base station (BS) communicates with a mobile station (MS) through relay stations (RSs). In one exemplary reliable relay-associated transmission scheme, the BS transmits data to the RSs using multicast or unicast. From the received packets, each RS calculates its reliability value according to a reliability function, which it informs the MS. The BS then generates a reliability metric to identify the RSs that are considered reliable. The reliable RSs transmit their information to the MS under a cooperative multicast transmission mode. Meanwhile, the unreliable RSs overhear the transmissions between the reliable RSs and the target MS. If the MS is unable to receive information from reliable RSs, the unreliable RSs can join the cooperative transmission to provide a higher cooperative diversity gain to the target MS.

摘要： A cooperative communication scheme is provided for a base station (BS) to communicate with a mobile station (MS) through a group of relay stations (RSs). The RSs, collectively referred to as a relay-associated group of RSs (R-group), serve the same target MS. The R-group may be formed during initial ranging or during periodical ranging of the MSs, according to the channel conditions between the MSs and the RSs. A reliable relay-associated transmission scheme provides fast recovery and reduces the burden on the BS. In one exemplary scheme, the BS transmits data to the R-group. To ensure that reliable transmission exists between the BS and the R-group, the BS initially sends the information to all the RSs in the R-group using multicast or unicast mode. In one embodiment, after receiving the packets from the BS, each RS in the R-group calculates its reliability value according to a reliability function which may depend on (a) the channel conditions between the BS and the RSs, (b) the channel conditions between the RSs and the MS, and (c) the load status at the RSs. The RSs then feedback their reliability values in a message (“relay-associated acknowledgement message” or R-ACK).
摘要翻译：提供了一种协作通信方案，用于基站（BS）通过一组中继站（RS）与移动台（MS）进行通信。统称为RS（R-group）的中继相关组的RS服务于相同的目标MS。根据MS和RS之间的信道条件，可以在初始测距期间或在MS的周期性测距期间形成R组。可靠的中继相关传输方案提供快速恢复并减轻BS的负担。在一个示例性方案中，BS向R组发送数据。为了确保BS与R组之间存在可靠的传输，BS首先使用多播或单播方式将信息发送到R组中的所有RS。在一个实施例中，在从BS接收到分组之后，R组中的每个RS根据可靠性函数计算其可靠性值，该可靠性函数可以取决于（a）BS与RS之间的信道状况，（b）信道 RS和MS之间的条件，（c）RS处的负载状态。然后，RS在消息（“中继相关确认消息”或R-ACK）中反馈其可靠性值。
