摘要： An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. Coupled load information is exchanged between base stations allowing a base station to determine an appropriate allocation of reverse link channel resources to mobile stations served by the base station. Since the allocation of reverse link channels resources are controlled directly by the base station, delays due to communications with a central controller are eliminated. As a result, adverse effects of load scheduling based on obsolete reverse channel information are minimized.

摘要： To enable point-to-multipoint communication services in an existing cellular communication system infrastructure, each member subscriber station, i.e., a subscriber station participating in such a service, is receiving a forward link shared channel, and in certain embodiments additionally a forward link dedicated channel. Because transmission on the forward link channels from neighboring sectors presents interference to the transmission from the sector serving the subscriber station, it is desirable to control the forward link channel transmission power to the minimum acceptable power. Additionally, a transmission form each member subscriber station on a reverse link channel presents interference to other subscriber stations. Therefore, it is desirable to control the reverse link channel transmission to the minimum signal level. Consequently, a method and apparatus for a power control that enables point-to-multipoint services in an existing infrastructure of a wireless cellular telephone system is disclosed.
摘要翻译：为了实现现有蜂窝通信系统基础设施中的点对多点通信服务，每个成员用户站（即，参与这样的服务的用户站）正在接收前向链路共享信道，并且在某些实施例中另外还提供了前向链路专用渠道。由于来自相邻扇区的前向链路信道上的传输对于从服务于用户站的扇区的传输产生干扰，所以期望将前向链路信道传输功率控制到最小可接受功率。此外，反向链路信道上的每个成员用户站的传输形式对其他用户站造成干扰。因此，期望将反向链路信道传输控制到最小信号电平。因此，公开了能够实现无线蜂窝电话系统的现有基础结构中的点对多点服务的功率控制的方法和装置。

摘要： Embodiments disclosed herein address the need in the art for efficient management of grant, acknowledgement, and rate control channels. In one aspect, a list associated with a first station is generated or stored, the list comprising zero or more identifiers, each identifier identifying one of a plurality of second stations for sending a message to the first station. In another aspect, sets of lists for one or more first stations are generated or stored. In yet another aspect, the messages may be acknowledgements, rate control commands, or grants. In yet another aspect, messages comprising one or more identifiers in the list are generated. Various other aspects are also presented. These aspects have the benefit of reduced overhead while managing grant, acknowledgment and rate control messaging for one or more remote stations.
