摘要： A method and system performs antenna tuning to minimize interference affecting signal reception within a wireless communication device. An antenna tuner controller determines whether the wireless communication device concurrently provides (a) simultaneous signal transmission and reception and (b) dual signal propagation. In response to determining that the wireless communication device concurrently provides the simultaneous signal transmission and reception and the dual signal propagation, the antenna tuner controller determines a current mode of operation corresponding to simultaneous signal transmission and reception and the dual signal propagation. Based on the mode of operation determined, the antenna tuner controller identifies a priority for performing antenna isolation to minimize interference affecting signal reception when the wireless communication device actively communicates within the specific mode of operation. In response to the identifying the priority for performing antenna isolation, the antenna tuner controller performs antenna impedance tuning that provides antenna isolation corresponding to the priority.

摘要： Methods and apparatus for serving content to a wireless device (106) are disclosed. In an embodiment, a gateway (114), or any other suitable device or system, determines that at least one message (e.g., a text or text-like message) containing a first pointer (e.g., a unicast URL) to the content (e.g., a web page) is to be transmitted via an emergency alert system (e.g., CMAS). In response thereto, the gateway (114) obtains the content using the first pointer and generates a second different pointer (e.g., a multicast/broadcast URL) to the content. The gateway (114) provides at least a portion of the at least one message and the second pointer for transmission via the emergency alert system (118). The gateway (114) also provides the content for transmission via a wireless multicast/broadcast channel (120) based on the second pointer.

摘要： A method and system provides an automatic frequency correction (AFC) within a wireless communication device. A synchronization controller estimates first and second frequency errors respectively associated with a first received signal corresponding to a first receiver path and a second received signal corresponding to a second receiver path. The synchronization controller determines a value and a type of target clock of a first AFC associated with the first frequency error. If the first AFC is not generated to target a shared clock such as a reference clock, the synchronization controller generates a second AFC to compensate for the second frequency error. However, if it is determined that the first AFC targets a shared clock, the synchronization controller generates the second AFC to compensate for the first AFC and the second frequency error. The synchronization controller synchronously applies the first and second AFCs to the relevant clocks.
