    摘要： Systems and methodologies are described herein that facilitate improved multi-radio coexistence between a Forward Link Only (FLO) radio and at least one non-FLO radio associated with a wireless device. As described herein, Overhead Information Symbol (OIS) transmissions scheduled by a FLO radio (such as transmissions on a dedicated OIS control channel or data transmissions containing embedded OIS information) can be given higher priority than other transmissions that collide with the OIS transmissions. In addition, transmissions scheduled by a non-FLO radio can be prioritized above respective non-OIS transmissions scheduled by a FLO radio, or alternatively non-OIS FLO transmissions can additionally be prioritized above transmissions scheduled by a non-FLO radio according to a measured amount of degradation present at the non-FLO radio. In a specific example described herein involving a Long Term Evolution (LTE) radio, degradation can be determined based on a number of successively missed Physical Uplink Control Channel (PUCCH) transmissions.

    摘要翻译： 本文描述了有助于改进的无前向链路（FLO）无线电与与无线设备相关联的至少一个非FLO无线电之间的多无线电共存的系统和方法。 如本文所描述的，由FLO无线电（诸如专用OIS控制信道上的传输或包含嵌入式OIS信息的数据传输）调度的开销信息符号（OIS）传输可被给予比与OIS传输相冲突的其它传输更高的优先级。 此外，由非FLO无线电调度的传输可以优先于由FLO无线电调度的相应的非OIS传输，或者替代地，非OIS FLO传输可以另外优先于上述由非FLO无线电根据测量的非FLO无线电调度的传输 在非FLO无线电中出现的退化量。 在涉及长期演进（LTE）无线电的本文描述的具体示例中，可以基于连续丢失的物理上行链路控制信道（PUCCH）传输的数量来确定劣化。

    摘要： A user equipment (UE) monitors coexistence issues of one or more associated communication resources. The UE initiates link recovery procedures (e.g., declaring a Radio Link Failure (RLF)) in response to the monitoring when a coexistence issue is detected. The UE can also access a new channel or a new Radio Access Technology (RAT) in response to initiating the link recovery. The network may have the ability to control whether the UE can initiate the link recovery.

    摘要： Automated PilotPN code conflict resolution using an access point with the assistance of one or more access terminals is disclosed. An exemplary method includes determining a set of access points, as well as determining a set of PilotPN codes used by the set of access points. Detection is then made concerning whether at least two access points of the set of access points have conflicting PilotPN codes. A first PilotPN code is allocated to one of the at least two access points having conflicting PilotPN codes. Additionally, one or more other PilotPN codes, which are distinct from the first PilotPN code, are allocating to remaining access points of the at least two access points having conflicting PilotPN codes. Corresponding apparatus and other exemplary methods are also disclosed.

    摘要： Methods and apparatus for supporting coexistence between two different radio access technologies (RATs), such as the Long Term Evolution (LTE) standard and one of the IEEE 802.16 standards, are provided. To accomplish this coexistence, a multi-mode base station (BS) may replace transmission gaps in a frame of a first RAT with subframes or symbols of the second RAT and transmit the resulting dual-RAT frame. In this manner, a single BS may support and communicate according to two different RATs simultaneously.

    摘要： Power control for wireless communication may involve determining the transmit power to be used by a wireless device. A wireless device using open loop power control may select a transmit power based on an open loop power equation where a parameter of the power equation may be based on one or more power control messages received from another wireless device. In some aspects, path loss may be estimated for open loop power control and a value for Offset_BSperSS may be obtained from information provided by a base station for closed loop power control. To facilitate a stable combined open-closed loop algorithm, open loop power control may be used to compensate channel changes based on reciprocity, and closed loop power control may be used to compensate interference variations (e.g., as compared to NI provided by a DCD message).
