Abstract: Exemplary embodiments include a system having a first wireless audio output device configured to connect to a source device via a first piconet and a second wireless audio output device configured to connect to the first wireless audio output device via a second piconet. A schedule of the first piconet includes a plurality of slots associated with an audio packet, a first subset of the slots used by the source device to transmit the audio packet, the first and second wireless audio output devices tuning to the first piconet to listen for the transmissions of the audio packet, and when, after a last one of the first subset of slots, the first or second wireless audio output devices did not receive the audio packet, the first and second wireless audio output devices exchange information via the second piconet such that the both wireless audio output device receive the audio packet.

Abstract: A user equipment (UE) including at least two antennas configured to allow the UE to communicate via a first connection. The UE selects a connection performance parameter associated with the first connection, generates historical measurement information for the at least two antennas based on the connection performance parameter, for the plurality of antennas, the historical measurement information indicating an expected performance associated with using a selected one of the at least two antennas for a packet transmission and selects, based at least on the historical measurement information, one of the at least two antennas for use in transmitting the packet.

Abstract: A wireless communication device includes a number of radio-frequency (RF) antennas and one or more radio circuits. Each radio circuit includes a receive (RX) chain to process RX signals and a transmit (TX) chain to process TX signals. An RF switch network couples at least one RF antenna to at least one radio circuit. A baseband processor controls a configuration of the RF switch network. The baseband processor determines a plurality of parameters and controls the RF switch network based on at least one of the parameters. The parameters are determined during a training interval including at least an inter-frame space (IFS). The configuration of the RF switch network is based on the determined parameters and is employed for selection of an antenna to improve a link performance when used for communication of a next packet following the IFS.

Abstract: A device and method selects an antenna configuration. The method performed at a user equipment includes determining at least one communication functionality that is being used, each communication functionality configured to utilize at least one antenna in a multi-antenna arrangement of the user equipment. The method includes receiving a first indication of whether a cellular communication functionality is being used, the cellular communication functionality configured to utilize at least one antenna in the multi-antenna arrangement. The method includes receiving a second indication of whether a coexistence condition is present. The method includes determining an antenna configuration for the multi-antenna arrangement to be used by the determined communication functionality based upon the determined communication functionality, the first indication, and the second indication. The method includes configuring the multi-antenna arrangement for the determined communication functionality based upon the antenna configuration.

Abstract: Apparatus and methods for authenticating and granting a client device (e.g., cellular telephone) access to a network. In one embodiment, a network service provider such as a cellular telephone company may distribute user access (e.g., Universal Subscriber Identity Module or “USIM”) credentials to a service manager via a USIM vendor. The services manager may maintain a list of authorized users. A user at a client may authenticate to the services manager. Once authenticated, the services manager may provide the user with a set of USIM credentials. When the user desires to use wireless network services, the user equipment may establish a wireless link between the user equipment and the network service provider. During authentication operations, the user equipment may use the USIM credentials to authenticate to the network service provider. Following successful authentication, the network service provider may provide the user equipment with wireless services.
Abstract translation: 用于认证和授予客户端设备（例如，蜂窝电话）接入网络的设备和方法。 在一个实施例中，诸如蜂窝电话公司的网络服务提供商可以经由USIM供应商将用户访问（例如，通用订户身份模块或“USIM”）凭证分发给服务管理器。 服务经理可以维护授权用户的列表。 客户端的用户可以向服务管理器进行身份验证。 一旦经过身份验证，服务管理器可以向用户提供一组USIM凭证。 当用户期望使用无线网络服务时，用户设备可以在用户设备和网络服务提供商之间建立无线链路。 在认证操作期间，用户设备可以使用USIM凭证来向网络服务提供商进行认证。 在成功认证之后，网络服务提供商可以向用户设备提供无线服务。

Abstract: Methods and apparatus enabling a mobile device to receive paging notifications from multiple networks. In one embodiment of the present invention, a first device connected to a first network momentarily ignores the first network, to monitor a second network instead. The first device identifies and prioritizes a list of applications of the first network; the prioritized listing allows the first device to preempt one of its lower priority tasks to monitor the second network for paging messages instead. The described methods and apparatus enable e.g., GSM paging for Class B cellular devices which are connected to GPRS NMO-2 type networks. The Class B cellular device can ignore certain GPRS data (which is tolerant to error), to decode GSM paging channels, which would otherwise be missed.
Abstract translation: 允许移动设备从多个网络接收寻呼通知的方法和装置。 在本发明的一个实施例中，连接到第一网络的第一设备暂时忽略第一网络，以代替监视第二网络。 第一设备识别并优先列出第一网络的应用列表; 优先级列表允许第一设备抢占其低优先级任务之一，而不是替代地监视第二网络的寻呼消息。 所描述的方法和装置能够例如连接到GPRS NMO-2型网络的B类蜂窝设备的GSM寻呼。 B类蜂窝设备可以忽略某些GPRS数据（这是容错误的），以解码GSM寻呼信道，否则会丢失。
