摘要： 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.

摘要： A wireless communication system and a detect-and-multiplex (DAM) spectrum sharing technique eliminate contention by secondary spectrum users by multiplexing multiple access methods. Suitable multiple access methods include time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDMA), space division multiple access (SDMA), orthogonal frequency division multiple access (OFDMA), spectral nulling (SN) or a hybrid scheme (HS) based on a combination of two or more of the above techniques. Unlike, detect-and-avoid (DAA) multiple access methods, the DAM method increases spectrum usage efficiency, and allows more users to share the same region of the spectrum.

摘要： An apparatus and a method proactively manage the load of an 802.11 WLAN based on one or more per-class station counts, in which the stations are classified according to access categories (ACs), user priorities (UPs), or services. Alternatively, the load of an 802.11 WLAN may also be proactively managed based on provisional or non-provisional per-class traffic specification (TSPECs), depending upon the status of traffic streams (TSs). Load balancing may be achieved by (a) collecting per-class station count information, either through an AP, or through exchanges with neighboring APs or wireless stations, and (b) proactively influencing association decisions between wireless stations and APs. A wireless station may be classified according to ACs, UPs, or services. Alternatively, load balancing may be achieved by (a) collecting provisional or non-provision per-class traffic specification (TSPEC) through an AP, or through exchanges with neighboring APs or wireless stations, and (b) proactively influencing association decisions between wireless stations and APs.

摘要： 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.
摘要翻译：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。

摘要： In a fast active scanning wireless network apparatus and method for quick determination of available access points (20), information about a candidate set of available access points (20) is obtained, and a candidate access point is identified from the candidate set. A mobile station (10) then queries the candidate access point with a probe request that designates the candidate access point as a sole responder. The probe request prevents other access points from contending for the medium of communication between the mobile station and the designated sole responder access point by excluding the attempt by other access points (20) to transmit probe responses. The apparatus and method thus increases the probability of a fast and successful probe request from the mobile station and subsequent response from the designated access point (20). The designated access point may also respond with a probe response of high priority, preventing intervention of communication.

摘要： 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.
