摘要： A method includes receiving, at a station, a first delivery traffic indication message (DTIM) assigned to a first delivery interval. The first DTIM is configured to indicate whether group-addressed traffic is scheduled for delivery during a beacon interval. The first delivery interval is larger than a second delivery interval associated with a second DTIM. The method further includes receiving the group-addressed traffic during the beacon interval.

摘要： Techniques to improve the standby time of a station in a wireless network are described. An access point may advertise or convey a maximum listen interval and/or an association timeout supported by that access point. A station may operate in a power-save mode and may wake up every listen interval to receive a beacon and any potential traffic for the station. The station may select a suitable listen interval based on the maximum listen interval. The station may be dormant for a longer duration than the listen interval and may become active at least once in every association timeout in order to keep the association with the access point alive. The access point may also send broadcast and multicast traffic that might be of interest to stations in the power-save mode less frequently and using a special indication message.

摘要： Methods and apparatus for determining the quality of a communication link transmitting a specified packet type are disclosed. The methodology includes configuring first packets, which share transmission characteristics with a specific packet type, such as a Voice over IP packet, such that the first packets experience similar communication link treatment as the specific packet type. The first packets are then transmitted over the communication link to a quality monitoring server located near a termination equipment of the particular communication link. Second packets, which are transmitted by the server in response to the first packets, are received and evaluated to determine the quality of the communication link based on characteristics of the second packets. Corresponding apparatus are also disclosed.

摘要： The disclosure is directed to an access terminal, and method for selecting an access point in a communications system. The access terminal may include memory and a processor. The processor may be configured to maintain in the memory a database containing a list of access points that have previously served the access terminal with at least a minimum quality of service, the processor being further configured to use the list to search for an access point to associate with, or search for an access point to handoff the access terminal to during operation. In addition to, or alternatively, the processor may also be configured to maintain in the database a second list of access points. The database may be used by the processor to search for an access point that is not on the second list to associate with, or handoff the access terminal to.

摘要： An access point generates beacons at different power levels at different times to provide an acceptable tradeoff between coverage area associated with the beacons and outage experienced at nearby access terminals. For example, a femto access point may transmit beacons at a relatively low power for a relatively long period of time to reduce interference at nearby access terminals that are being served by a macro access point. The femto access point may then transmit beacons at a relatively high power for a relatively short period of time to enable nearby access terminals to receive the beacons. Also, a given transmit chain may be used to provide frequency hopping of high and low power beacons.
摘要翻译： 接入点在不同时间产生不同功率电平的信标，以提供与信标相关联的覆盖区域和在附近接入终端处经历的中断之间的可接受的折中。 例如，毫微微接入点可以以相对较低的功率在相对长的时间段内发送信标，以减少正在由宏接入点服务的附近接入终端的干扰。 毫微微接入点然后可以在相对较短的时间段内以相对高的功率发送信标，以使附近的接入终端能够接收信标。 此外，给定的发射链可以用于提供高和低功率信标的跳频。

摘要： Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

摘要： Transmission by a first node may be controlled based on a status of a second node. The status of the second node may indicate, for example, whether the second node will be communicating with the first node. Thus, if it is determined based on the status of the second node that the second node may not be communicating with the first node, transmissions by the first node may be temporarily disabled until there is a change in status, and vice versa.
摘要翻译： 可以基于第二节点的状态来控制第一节点的传输。 第二节点的状态例如可以指示第二节点是否将与第一节点进行通信。 因此，如果基于第二节点的状态确定第二节点可能不与第一节点通信，则第一节点的传输可以被暂时禁用，直到状态发生变化，反之亦然。

摘要： An access terminal scans for nearby access points and maintains a candidate list of access point with which the access terminal may associate in the event the access terminal's communication with its current access point deteriorates for some reason. This search procedure may be performed in a proactive manner whereby the access terminal repeatedly performs scans and updates its list of candidate access points when it is powered on. In some aspects, the search procedure used by the access terminal may be based on a state of the wireless device. In addition, different states of the access terminal may be associated with different optimization criteria.
摘要翻译： 在接入终端与其当前接入点的通信由于某种原因而恶化的情况下，接入终端扫描附近的接入点并维护接入终端可以关联的接入点的候选列表。 该搜索过程可以以主动方式执行，由此当接入终端上电时，接入终端重复执行扫描并更新其候选接入点列表。 在一些方面，接入终端使用的搜索过程可以基于无线设备的状态。 此外，接入终端的不同状态可以与不同的优化准则相关联。
