Adaptive channel coding using polarization

Methods, systems, and devices are described for wireless communications at a wireless device. A wireless device may adaptively select a parity check matrix to increase the reliability of signal transmission by adapting to different channel statistics and channel types (e.g., erasure channels, channels with additive white Gaussian noise, and channels with discrete or continuous alphabets). For example, polarization codes (i.e., codes based on rows of a polarization matrix) may be used to construct parity check matrices “on-the-fly” given an estimation of dynamic channel conditions or diverse channel structures. The channel may be decomposed into polarized sub-channels corresponding to the polarization codes, and mutual information profiles may be determined for each of the polarized sub-channels. The parity check matrix corresponding to the polarization codes may be constructed based on the mutual information profile of all polarized sub-channels. The wireless device may encode or decode data based on the constructed parity check matrix.

System and method for flash call setup in an internet protocol based cellular network

A telecommunications system and method is disclosed for decreasing the average call setup time in a cellular network by using an Internet Protocol based cellular network. Call information (such as routing information, channel types, etc.) for a particular call initiated by a calling Mobile Station (MS) can be stored in a call cache within a serving Mobile Switching Center (MSC) to immediately allow the same call to be re-established without tying-up circuits. A call cache identifier (CCI) is assigned to that call cache and passed to the calling MS. When the MSC receives a call from the calling MS, the MSC determines whether a CCI is included with the call. If not, call setup proceeds as normal, and the MSC creates a call cache for the call, assigns a CCI to the call cache and returns the CCI to the calling MS. If a CCI is received with the call, the MSC accesses the call cache associated with the received CCI, and uses the call setup information stored in the call cache to re-establish the call.

Method, Mobile Station and Base Station System for Transmitting Data Packets in a Packet Data Communication System

The object of the present invention is to provide a solution wherein data packets can be transmitted in a mobile packet data communication system between a mobile station (500) and a base station system (510) over an air interface (520) with a short initial access time delay, without unnecessary consumption of system resources and the mobile station's battery resources. This is achieved by using a novel channel type called non-scheduled traffic channel for transmitting data packets between a mobile station and a base station system. The non-scheduled traffic channel is accessible to a selected number of the mobile stations residing in a cell. The non-scheduled traffic channel is used such that a data packet is transmitted from the mobile station (500) to the base station system (510) or from the base station system (510) to the mobile station (500) over the non-scheduled traffic channel without any connection being established between the mobile station and the base station system before the data packet is transmitted and without the non-scheduled traffic channel being scheduled for the transmission before the data packet is transmitted. An identifier would be appended to the data packet such that the mobile stations in the cell would know to which mobile station the packet is addressed, in case of downlink transmission, and such that the base station system would know from which mobile station the data packet was transmitted, in case of uplink transmission.

Channel sharing by diverse multiframes in a wireless communications network

A wireless communication system and method provide air interface channels using diverse multiframe types on a single frequency carrier. Physical channels for a single frequency carrier are defined as time slots, a series of consecutive time slots define a frame, and a plurality of multiframe types are defined for the single frequency carrier as including different numbers of consecutive frames. By multiplexing a plurality of multiframe types onto a single frequency carrier, diverse channels types such as traffic channels, broadcast control channels, and common control channels can be accommodated on the same frequency carrier to enable efficient utilization of frequency resources. In one exemplary implementation, a first multiframe type is defined as having x consecutive frames, a second multiframe type is defined as having y consecutive frames, and a third multiframe type is defined as having z consecutive frames. Thus, the frame number for the first multiframe type is counted modulus x, the frame number for the second multiframe type is counted modulus y, and the frame number for the third multiframe type is counted modulus z. The first, second, and third multiframe types are further assigned to different time slots. For example, if a frame is defined as having three time slots, the first multiframe type may be assigned to the first time slot, the second multiframe type may be assigned to the second time slot, and the third multiframe type may be assigned to the third time slot.
