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： 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： The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. While communicating over the packet-switched network, the device negotiates a sleep interval that is longer than the ordinary interval available using the packet-switched network. In this manner, the device wakes less frequently and thereby conserves power. A buffering system is included so that data directed towards the device while it is asleep may be buffered for later delivery when the device awakens.

摘要： Methods and apparatus for system selection in a multimode wireless device are disclosed. The method and apparatus afford selection of a wireless communication system access technology from a number of wireless system access technologies supported by a wireless device. Selection is accomplished by storing identification information concerning access technologies pertaining to a first group of wireless system access technologies, such as 3GPP2, in a search database, which concerns the priority of access technologies pertaining to another group of access technologies, such as 3GPP. Selection of a preferred wireless communication system access technology from one of the wireless access technology groups is then based on the identification information stored in the search database.

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： Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

摘要： Transmit power for a user equipment (UE) is set by a Home NodeB (HNB) in response to interference at a nearby macrocell. The HNB monitors an interference level to the macrocell from a UE communicating with the HNB. An acceptable transmit power for the UE is determined by the HNB in response to the interference level. A power change indicator is transmitted from the HNB to the UE to adjust the transmit power of the UE. In some cases, the interference may be estimated from a busy indicator from the macrocell and the HNB sends a modified version of the busy indicator to the UE to adjust the transmit power of the UE. In other cases, the HNB estimates a path loss for the UE based on received signal power from the macrocell and signals a transmit power change to the UE, if needed, based on the estimated path loss.
摘要翻译： 用户设备（UE）的发射功率由家庭节点B（HNB）响应于在附近的宏小区的干扰来设置。 HNB从与HNB通信的UE监视到宏小区的干扰电平。 响应于干扰电平，由HNB确定UE的可接受发射功率。 从HNB向UE发送功率变化指示符，以调整UE的发射功率。 在一些情况下，可以从宏小区的忙指示符估计干扰，HNB向UE发送忙指示符的修改版本，以调整UE的发射功率。 在其他情况下，HNB基于来自宏小区的接收信号功率来估计UE的路径损耗，并且如果需要，则基于所估计的路径损耗来向UE发送功率变化信号。
