摘要： In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign resources, such as transmit power or frequencies, to wireless coverage areas serving particular altitude ranges in a proportion that is commensurate with the number of WCDs being served by these particular altitude ranges. As a result, RAN and WCD performance may improve.

摘要： A mobile station transmits a message by transmitting an access probe that includes the message preceded by a preamble. The mobile station selects the length of the preamble from among a first preamble length and a second preamble length. The second preamble length is greater than the first preamble length. The mobile station makes the selection based, at least in part, on the distance between the mobile station and the mobile station's primary base transceiver station (BTS). If the distance is greater than a threshold distance, the mobile station selects the second preamble length. If the distance is less than the threshold distance, the mobile station selects the first preamble length, provided that an idle handoff to a neighboring BTS that is more than the threshold distance away is unlikely.

摘要： A method and system is disclosed for selectively scheduling control channel messages ahead of traffic channel data. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of a particular control packet to access terminals, the RAN will determine if there is a particular traffic packet in active transmission that is classified according to best effort service (or similarly-characterized service class), and further if at least a threshold number of a nominal number of time-slot segments of the particular traffic packet remain untransmitted. If such a traffic packet is identified, the RAN will cancel transmission of the particular traffic packet and replace it with immediate transmission of the particular control packet.
摘要翻译：公开了用于在业务信道数据之前有选择地调度控制信道消息的方法和系统。当至少根据IS-856操作的无线通信系统中的RAN确定在向接入终端发送特定控制分组时存在延迟条件时，RAN将确定是否存在主动传输中的特定业务分组根据尽力服务（或类似特征的业务类别）进行分类，以及进一步地，如果特定业务分组的至少一个阈值数量的时隙段的标称数目保持未被发送。如果识别出这样的业务分组，则RAN将取消特定业务分组的传输，并将其替换为特定控制分组的即时传输。

摘要： A method and system is disclosed for enhanced idle-state sector selection during hybrid-mode operation of an access terminal. A hybrid access terminal engaged in an IS-856 data communication session in a hybrid IS-2000/IS-856 wireless communication system will, responsive to a handoff of the IS-856 session, select a sector for its next, upcoming IS-2000 idle-state scan prior to the start of the scan. The selection will be made during an interval between IS-2000 idle-state scans, thereby reducing or eliminating the possible need for idle-state handoffs during idle-state scans, and resulting in shorter idle-state scans and better IS-856 performance.

摘要： A method and apparatus for handing off packet-transmission between sectors of a wireless communication system is disclosed herein. During transmission of a packet from an access network to an access terminal, the access terminal determines that the packet should theoretically be transmitted to the access terminal in fewer timeslots in another sector than the number of allowed timeslots remaining for the packet transmission in a current sector. In response, the access terminal abandons packet transmission in the current sector and hands off to the other sector, in an effort to increase throughput and save air interface resources.

摘要： A method and system is disclosed for setting forward-link power for an access terminal operating in a coverage area of a wireless communication system, whereby power is redistributed from access terminals operating in the same coverage area and having forward-link power in excess of their needs for maintaining acceptable service quality, to an access terminal that is in need of additional forward-link power in order to attain a desired or required level of service quality. Following a determination that a given access terminal is requesting a forward-link transmission power level that exceeds a first threshold power level, a number of other access terminals are identified as each having requested a respective decrease in forward-link transmission power level by an amount at least as large as a respective threshold amount. Forward link power to the given access terminal is then increased by an incremental amount, and the forward-link transmission power level to each of the number of other access terminals is decreased by a respective decremental amount, wherein the sum of all the respective decremental amounts equals at least the incremental amount.

摘要： A method of selecting a type of resource-allocation to use for a call in a cellular wireless system, such as selecting a type of radio configuration to use for the call. According to the method, resource-availability in one more adjacent coverage areas may be used as a basis to select the type of resource-allocation to use in a current coverage area. For instance, given the choice between a radio configuration that consumes less base station power and a radio configuration that consumes more base station power, the radio configuration consuming more base station power may be selected if base station sufficient power is available in one or more adjacent coverage area(s), and the other radio configuration may be selected if insufficient base station power is available in the one or more adjacent coverage area(s). Distance between the mobile station and a current base station may be considered as well.

摘要： A method and apparatus for selecting channel elements in a wireless communication system based on their performance history. Data is collected indicating the performance of various channel elements over time, preferably eliminating from consideration any performance degradation due to air interface (e.g., radio frequency) issues. The data is then used to sort the channel elements in a priority order, from best-performing to worst-performing. When a channel element is to be selected for use in connection with an air interface channel (e.g., traffic channel or control channel), the channel element is then selected in accordance with the priority order, such as by selecting the channel element that has performed best over time. The priority-based selection of channel elements can thus leave poor-performing channel elements for use as a last resort, which can be advantageous in times of heavy network loading for instance.
