Disclosed are an apparatus and method for providing packet data service from a radio network controller (RNC) to user equipment (UE) in a mobile communication system. A radio bearer (RB) of a predetermined channel type is configured to compress and de-compress headers of packets passed between the RNC and the UE. The packet data service is provided from the RNC to the UE via the RB. When the channel type is changed, configuration information associated with an RB of the changed channel type is determined. Header compression (HC) context used in the RB of a previous channel type is acquired according to the configuration information and the RB of the changed channel type including the acquired HC context is configured. The packet data service is continuously provided via the RB of the changed channel type. Therefore, the invention reduces waste of radio resources that is due to a channel type change and delay that is due to system reset.

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.

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.

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.
