Abstract:
Methods, systems and computer program products are provided through which a wireless terminal participating in a packet-switched communications session may temporarily suspend the session, for example, upon receipt of an incoming circuit-switched call. The wireless terminal may notify a server associated with the packet-switched session of receipt of the incoming circuit-switched call, and may also notify the server when the packet-switched session may be resumed. In embodiments of the present invention implemented in GSM networks, one or more of the notification messages may be transmitted to the server over the SMS data bearer.
Abstract:
An electronic device includes a Rake receiver for receiving wireless signals, wherein the Rake receiver includes a predetermined number of fingers and a combiner. The Rake receiver also includes a channel detection circuit configured to identify at least one channel tap in a received signal, and a placement circuit configured to place a finger of the predetermined number of fingers at a location corresponding to the at least one identified channel tap. If all of the predetermined number of fingers are not associated with a corresponding channel tap, unplaced fingers of the predetermined number of fingers are placed at locations based on a signal-to-interference ratio estimate at an output of the combiner.

Abstract:
Methods, systems, and computer readable media for reducing the impact of false downlink control information (DCI) detection in long term evolution (LTE) physical downlink control channel (PDCCH) data are disclosed. According to one method, an LTE multi-UE simulator receives PDCCH data from an evolved node B (eNode B). The LTE multi-UE simulator applies blind DCI decoding to decode at least one DCI value from channel control elements that carry the PDCCH data. The LTE multi-UE simulator applies at least one false DCI detection countermeasure to identify as true or false DCIs from the DCIs detected using the blind decoding.

Abstract:
An improved coding and decoding process is disclosed to determine the ending state of a convolutional decoding using Viterbi algorithm without the use of tail bits. The most important information bits are first coded with a block code. The block code word and the rest of the information bits are then split into several bursts. Each burst is coded with a convolutional code. The most important information bit part of the block code word is then placed in the beginning of the code burst for the convolutional encoder. The parity bit part can be placed between the end of the most important information bit part and the end of the code burst. In the convolutional decoding process for each burst, the ending state is determined by detected valid block code word after combining the convolutional decoding processes for all the bursts. The performances of average BER and missed detection rate can be optimized by moving the placement of the parity bit in each message code burst.
