Abstract: A method and arrangement for improving channel decoding performance in a radio receiver. Data bits from previously decoded messages are analyzed to provide a priori information to a channel decoder which is decoding a currently received message of the same type. The invention may analyze both the header and data fields of the previously decoded message frames to detect fields that are unchanging or rarely changing from one frame to the next. Probabilistic knowledge (a) of the bits in these unchanging or rarely changing fields is then used to improve the decoding performance for the current message. If a message cannot be successfully decoded, soft values of the bits are stored and then soft-combined with selected bits in the next message received prior to decoding. The invention is applicable to any type of message that has data components that are repeated with varying degrees of probability in successive transmissions.

Abstract: A radio network resource controller directs a first network node associated with a first cell region, or a wireless terminal in communication through the first cell region, to measure and report radio resource-related data selected from the group consisting of: resource activity per channel; the number of transmitted power samples that exceed a threshold over a measurement period; and, channel quality samples that exceed a quality threshold. The controller then receives at least one measurement report of the radio resource-related data and, as a function of the radio resource-related data in the first cell region, dynamically reallocates the distribution of resources, such as radio-frequency channels associated with uplink and downlink communications, between the first cell region and at least a second cell region.

Abstract: A method (200) for a cellular system (100), with an RBS (120) which controls a cell (110) with User Equipments UE (130, 140). The RBS and the UEs exchange data which may comprise sequence numbers, and exchange reports on whether or not data has been received successfully, so that both the UE and the RBS can be the reporting party and the report receiving party. The reporting party sends a report (210) to the report receiving party on whether or not data has been received successfully, together with data to the report receiving party or to another party in the cell. The reporting party decides (220) the contents of the report using one of the following priority rules: Data with lower delay tolerance is given priority, Data detected as received in error is given priority, Data is given priority according to block sequence numbers.

Abstract: A radio network system employing a method with dynamic adjustment of the power offset that provides a “per-UE”-NACK to ACK power offset calculation method instead of using a fixed offset for all users in the cell is disclosed. Also for each UE, the power offset can adjusted dynamically. The adjustment is based on the error event of NACK to ACK. When an error event of NACK to ACK happens, the offset is increased, otherwise the offset is decreased. Hence, the offset can be controlled for each User Equipment for the duration of a call starting from some standard configured value is calculated and used rather than a fixed offset.

Abstract: The present invention sends multiple versions of a multimedia packet to the base station, and, based on the radio channel and traffic characteristics, an appropriate version of the multimedia packet is selected to send to the mobile station at a given time. In this way, source transmission is improved to instantaneous conditions. The steps of the present invention are performed in conjunction with RTP used for multimedia transmission over internet protocol (IP) networks. In a first embodiment, the multiple versions are sent to the base station in the same RTP packet, and the base station strips out the extraneous versions. In a second embodiment, the base station receives multiple RTP packets having identical information in the packet header in many fields, and selects an appropriate one among these for transmission to the mobile station, discarding the rest.

Abstract: A wireless communication system can include polarization agile antennas to enable adaptation to the polarization characteristics of a changing propagation channel. In one embodiment, a mobile terminal can include one or more polarization-agile antennas, and can select polarization orientations that are preferentially propagated through the changing propagation channel. In another embodiment, a mobile terminal having two polarization-agile antennas can provide spatial diversity, polarization diversity, or combinations of both. Multiple-input multiple-output (MIMO) systems can include polarization-agile antennas to allow for switching between spatial and polarization diversity, combined spatial and polarization diversity, and various Eigen channel decompositions using spatial, polarization, and combined spatial and polarization dimensions. An extended polar normalization provides enhanced fidelity for methods of communications system modeling.

One or more data sessions of at least one user terminal network are determined to be handed over based on the sent reports and a core network anchor and a terminal anchor are directed to execute a handover by re-routing said determined data sessions from one access path to an alternative access path.

Abstract: A method and apparatus for enabling communication of IP multimedia content to a called user during a circuit-switched call between a calling terminal (A) having called a primary communication unit (B1), when the call has been forwarded to a secondary communication unit (B2). The calling terminal receives a connected number during a call set-up procedure, e.g. by subscribing to a called line presentation (COLP) service. The calling terminal stores the received connected number and determines multimedia capabilities of the secondary communication unit based on the connected number. Available multimedia options can then be determined based on the multimedia capabilities of the secondary communication unit.
