Abstract: A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARQ) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased.

Abstract: A wireless communication system (100) is configured to send signaling messages through a cell broadcast service (CBS). CBS message pages used to transport signaling messages are identified by assigned message identifiers. Mobile devices (114) within the communication system (100) recognize the CBS messages transporting signaling messages by the message identifiers and pass the signaling messages to an appropriate application or control program module. The message identifier may be used to specify the application or control program module to process the signaling message. The signaling messages transported by the CBS may be used in controlling a multicasting or broadcasting service. Duplicate copies of the CBS message pages may be transmitted and then buffered at the mobile device (114) as they are received until all parts of the signaling message have been received.

Abstract: A mobile communication device, and a method of operating a mobile communication device, includes storing at least one frame of a communication signal received from a network, and applying flow control to the lower layers to support network reselection. According to one aspect of the invention, a message is transmitted indicating that a virtual bearer mode of operation is supported by the mobile communication device. The mobile communication device selectively operates in the virtual bearer mode depending upon the response received following such transmission. Additionally, flow control may advantageously be dependent upon detecting that a cell change is imminent.

Abstract: An apparatus and method to reduce uplink compressed mode monitoring in a communication device includes a first step of monitoring a neighboring channel and measuring a channel signal strength. An desense of the monitoring receiver is estimated to determine a threshold, which is compared to the signal strength. If the signal strength is less than the threshold, a new neighboring channel is monitored to see if the signal strength changes. If not, the measured signal is probably interference. In this case, the communication device can request uplink compressed mode to get an accurate signal strength measurement. Only under these condition are uplink compressed mode called for, instead of full time compressed mode, thereby maintaining data capacity.
