摘要： Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.

摘要： An access terminal (AT) and a data-optimized cellular communication radio network (RN) negotiate a set of packet sizes for use on a reverse link between the AT and the RN. The negotiated set of packet sizes may differ from the default set of packet sizes defined in an existing standard, such as 1xEV-DO Revisions A and B. The packet sizes in the negotiated set may be tailored to provide a good fit with an application transmitting data on the reverse link, such as a voice encoder of a voice over Internet Protocol (VoIP) application. The AT and the RN communicate using the negotiated set of packet sizes. The packet sizes of the negotiated set may be mapped to the same reverse rate indicator (RRI) channel codewords as are defined in systems operating under the standard. Packing efficiency is thus increased, and higher capacity for delay-sensitive applications is achieved.

摘要： A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access network in the communication system, and passing the RAB to multiple digital filters to produce filtered RABs. The reverse link data rate is determined based on these filtered values of the RABs. From the filtered RAB values a continuous fluid power level is determined for each rate update. The access terminal maps the continuous fluid power level to actual physical transmissions by dithering among discrete power levels allowed by the physical layer.

摘要： An access terminal (AT) in a cellular communication system is configured to operate in an active hold (AH) state, a transitional state between traffic and dormant states. The AT applies power to its transmit chain with a low duty cycle while in the AH state, conserving battery power. To improve robustness of the communications, the radio network may power control the AT to a higher level relative to the power control level of the AT in the traffic state. Transition from the traffic state to the AH state may be initiated after a brief period of inactivity on the reverse link. The AT may remain in the AH state while receiving forward link payload data. Transmission of a reverse link payload packet in the AH state may initiate transition to the traffic state. A prolonged period of inactivity may initiate a transition from the AH state to the dormant state.
摘要翻译：蜂窝通信系统中的接入终端（AT）被配置为在主动保持（AH）状态，业务和休眠状态之间的过渡状态下操作。 AT在AH状态下以低占空比向其发射链进行供电，从而节省电池电量。为了提高通信的鲁棒性，无线电网络可以将AT控制在相对于业务状态的AT的功率控制级别更高的级别。从交通状态到AH状态的转换可以在反向链路上短暂的不活动状态之后启动。 AT可以在接收到前向链路有效载荷数据时保持在AH状态。在AH状态下的反向链路有效负载分组的传输可以启动到业务状态的转换。长时间的不活动可能会从AH状态转移到休眠状态。

摘要： A data-optimized communication system provides support for legacy access terminals, such as access terminals operating under the 1xEV-DO standard. The system also supports multiple-input multiple-output (MIMO) communications with access terminals configured to support MIMO. A number of MIMO spatial signatures are predefined or negotiated. MIMO rank and an identifier of the spatial signature determined at the MIMO access terminal are sent on the I-Branch and Q-Branch of the existing 1xEV-DO structure. In one embodiment, 1-bit rank and 3-bit spatial signature are transmitted through the I-Branch as a 4-bit symbol, replacing the data rate control (DRC) channel. In another embodiment, a 4-bit spatial signature is transmitted through the I-Branch, also replacing the DRC channel. A 2-bit rank is transmitted together with a 4-bit DRC channel through the Q-Branch. The 2-bit rank and the DRC channel can be distinguished because they are sent using different orthogonal codeword Walsh covers.
