摘要： Method and apparatus for adjusting the transmission power of base stations in simultaneous communication with a mobile station. The methods described provide for the transmission power of the base stations to be aligned. In the first exemplary embodiment, the transmitters are attached to a separate control unit through communication links. The control unit then derives the most likely command stream and send that to the base stations. In the second exemplary embodiment, the control unit periodically receives the final or average transmit level in a period and an aggregate quality measure for the feedback during a period from each of the transmitters. The control unit determines the aligned power level and transmits a message indicative of the aligned power level to the transmitters.

摘要： Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

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： A dynamic shared forward link channel (or “data” channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.
摘要翻译：使用动态共享前向链路信道（或“数据”信道）将组播数据发送到一组无线设备，例如使用用于数据信道的公共长码掩码。参考功率控制（PC）位也在数据通道上发送并用于信号质量估计。共享的前向链路控制信道用于向各个无线设备发送特定于用户的信令，例如对于每个无线设备使用时分复用（TDM）和唯一长码掩码。共享的前向链路指示符信道用于向无线设备发送反向链路（RL）PC比特，例如使用TDM。数据通道由接收数据通道的所有无线设备共同供电控制。控制和指示器通道由每个无线设备单独进行功率控制，使得在这些信道上为无线设备发送的信令和RL PC位被可靠地接收。

摘要： An apparatus, system, and method efficiently manage reverse link communication in a communication system having geographically distributed base stations. A base station functioning to at least one mobile station as a non-serving active base station estimates an expected coupled load due to the at least one mobile based on a previous total coupled load. The base station determines a total available capacity based on the difference between the total capacity of the base station and the estimated expected coupled load. The base station allocates reverse link resources to other mobile stations served by the base station so as not to exceed the total available capacity. 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： Techniques for efficient signaling to and from a plurality of mobile stations are disclosed. In one embodiment, a subset of mobile stations may be allocated a portion of the shared resource with one or more individual access grants, another subset may be allocated a portion of the shared resource with a single common grant, and yet another subset may be allowed to use a portion of the shared resource without any grant. In another embodiment, an acknowledge and continue command is used to extend all or a subset of the previous grants without the need for additional requests and grants, and their associated overhead. In one embodiment, a traffic to pilot ratio (T/P) is used to allocate a portion of the shared resource, allowing a mobile station flexibility in selecting its transmission format based on T/P.
