Embodiment Construction

[0030] figure 1 A wireless communication system 100 is shown with multiple wireless devices in accordance with some embodiments. Wireless communication systems 100 have been widely deployed to provide various types of communication content such as voice, data, and so on. The wireless device may be a base station 102 or a wireless communication device 104 . The wireless communication device 104 may be configured to implement enhanced GSM cell acquisition. For example, the wireless communication device 104 may be configured to rapidly search across multiple radio access technologies (RATs) and / or multiple frequency bands for serving cells.

[0031] A base station 102 is a station that communicates with one or more wireless communication devices 104 . Base station 102 may also be referred to as and includes an access point, base transceiver station (BTS), broadcast transmitter, Node B, evolved Node B, etc. , evolved Node B, and so on, some or all of the functions. The term "...

Abstract

Embodiments of the present invention include devices, systems and methods for prevention of dropped calls. For example, a method for wireless communication is described. A wireless communication device begins an acquisition. A scan of absolute radio frequency channel numbers for supported bands is performed using a wideband receiver. The absolute radio frequency channel numbers that include a frequency correction channel are identified. A synchronization channel is decoded using data corresponding to the identified one or more frequency correction channels. Other aspects, embodiments, and features are also claimed and described.
