摘要： To improve performance in devices capable of communication using multiple radio access technologies (RATs), a gap pattern may be constructed in which a first RAT is quieted during certain times to allow for a second RAT to operate without interference. Gap patterns may be constructed based on timeline constraints, such as grant scheduling and HARQ performance, or based on desired performance levels of one or more of the RATs. Gap patterns may be selected by a user equipment or base station. Gap patterns may be selected to protect information in certain subframes. Potential gap patterns may be assigned weights indicating their desirability.

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).
摘要翻译：用于无线通信的功率控制可以涉及确定由无线设备使用的发射功率。使用开环功率控制的无线设备可以基于开环功率方程来选择发射功率，其中功率方程的参数可以基于从另一无线设备接收的一个或多个功率控制消息。在一些方面，可以针对开环功率控制估计路径损耗，并且可以从基站提供的用于闭环功率控制的信息获得Offset_BS 的值。为了促进稳定的组合开环闭环算法，可以使用开环功率控制来基于互惠来补偿信道变化，并且可以使用闭环功率控制来补偿干扰变化（例如，与由DCD消息提供的NI相比较）。

摘要： Systems and methodologies are described that facilitate resource scaling for inter-access point fairness in a wireless communication system. As described herein, an offered load of an access point can be determined based on one or more loading metrics relating to associated terminals, throughput, data rate, quality of service (QoS), or the like. Based on the determined offered load of an access point, resources used by the access point and/or power utilized for communication over those resources can be scaled based on a comparison of the offered load of the access point to a nominal or default offered load. Centralized techniques for resource scaling are described herein, wherein one or more centralized controllers coordinate resource scaling with respective access points via backhaul messaging. In addition, distributed techniques for resource scaling are described herein, wherein neighboring access points communicate with each other via over-the-air messaging to determine a local optimal resource apportionment.
