    • In a system including one or more femtocells within a service area of a macrocell, a method includes: (a) receiving from a base station of each femtocell information regarding available resources at the femtocell; (b) measuring an signal-interference-to-noise ratio (SINR) at a mobile station relative to the macrocell and each femtocell; and (c) selecting for the mobile station one of the femtocells for a hand-off, wherein the femtostation is selected based on the combined capacity of the macrocell and the femtocells after the hand-off. When a hand-off to a femtocell is not allowed, a method for determining whether or not a spectral resource of the macrocell is reused includes (a) receiving from a base station of the macrocell a first set of spectrum-sensing data, the first set of spectrum-sensing data comprising spectrum-sensing data of mobile station of the macrocell; (b) receiving from one or more mobile stations associated with the femtocells a second said of spectrum-sensing data; and (c) based on the first set of the spectrum-sensing data and the second set of spectrum-sensing data, determining whether or not to reuse in a femtocell a portion of a spectrum used by the macrocell. The determining step may be carried out at a base station of a femtocell, and the method further requires sensing a spectrum at the base station of the femtocell to obtain a third set of spectrum-sensing data, which is also used in determining whether or not to reuse the portion of the spectrum used by the macrocell.
    • 在包括在宏小区的服务区域内的一个或多个毫微微小区的系统中,一种方法包括:(a)从基站接收每个毫微微小区关于毫微微小区上的可用资源的信息; (b)测量移动站相对于宏小区和每个毫微微小区的信号 - 干扰信噪比(SINR); 以及(c)为所述移动台选择所述毫微微小区之一用于切换,其中,所述毫微微站是基于所述宏小区和所述毫微微小区在所述切换后的组合容量来选择的。 当不允许对毫微微蜂窝进行切换时,用于确定宏小区的频谱资源是否被重用的方法包括:(a)从宏小区的基站接收第一组频谱感测数据,第一组 一组频谱感测数据,包括宏小区的移动台的频谱感测数据; (b)从与所述毫微微小区相关联的一个或多个移动站接收第二所述频谱感测数据; 和(c)基于第一组频谱感测数据和第二组频谱感测数据,确定是否在毫微微小区中重用由宏小区使用的频谱的一部分。 确定步骤可以在毫微微小区的基站执行,并且该方法还需要在毫微微小区的基站处感测频谱以获得第三组频谱感测数据,其也用于确定是否 以重新使用宏小区使用的频谱的部分。

    • A method and an apparatus select an access point (AP) in a wireless LAN to associate or reassociate, based on considerations that take into account the quality-of-service (QoS) status of the stations (STAs) and the potential hidden terminal effect. The method utilizes advertised or requested information obtained from an AP which includes the QoS status in each basic service set (BSS) and estimates the potential hidden terminal (HT) effect based on local channel sensing by the STA. The method selects the AP in a manner that reduces the possibility of collision from equal and higher priority HTs, thus providing greater transmission throughput and improving performance.
    • 一种方法和装置,基于考虑到站(STA)的服务质量(QoS)状态和潜在隐藏终端效应的考虑,选择无线LAN中的接入点(AP)来关联或重新关联 。 该方法利用从每个基本业务集(BSS)中包括QoS状态的AP获得的通告或请求信息,并且基于STA的本地信道感测来估计潜在的隐藏终端(HT)效应。 该方法以降低来自相同和较高优先级的HT的冲突的可能性的方式选择AP,从而提供更大的传输吞吐量并提高性能。

    • Apparatuses and methods are disclosed herein for implementing dormant mode with paging in a WLAN. Power savings in the computing device and reduction in traffic across the network are achieved by requiring a computing device to inform the WLAN of its location only when it crosses a paging area boundary or is to receive IP traffic. Dormant mode with paging is implemented in a protocol that supports dormant functionality and paging functionality but does not itself provide methods or standards for implementing such functionality, such as the IEEE 802.11. The methods and apparatuses disclosed herein provide the methods needed to implement dormant mode with paging in such a protocol. Generally, the methods and apparatuses for implementing dormant mode with paging basically include (1) establishing paging areas; (2) communicating access group information to a computing device; and (3) locating a computing device.
