Abstract: An invention relates to methods for transmitting a buffer status report (BSR) in a mobile communication system, more particularly to the definition of rules for triggering, generating and transmitting BSRs. The invention also relates to a data transmission method utilizing new rules to decide data of which radio bearers is transmitted within a given transmission time interval. Moreover, the invention relates to scheduling method for radio resources that is taking into account additional scheduling-relevant information from the buffer status reporting and/or data transmission method. To avoid unnecessary grants from the network and to suggest an advanced handling of data transmissions the invention suggests a buffer status reporting and data transmission schemes that take into account the scheduling mode of data of radio bearers pending for transmission to decide whether to report on it in a buffer status report, respectively, whether to multiplex the data to a transport block for transmission.

Abstract: The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed control channel signal. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.

Abstract: The present invention relates to configuring search spaces of at least two coexisting control channels in a communication system. In particular, the control channels are defined in at least partially overlapping regions, wherein the overlapping is in the time and/or frequency domain. This configuration enables coexistence of the at least two channels in the same resource grid and better utilization of the resources. Furthermore, it enables sharing of the reference signals.

Abstract: A radio communication base station device which can reduce the number of judgment times for a control signal in a mobile station, thereby suppressing power consumption by the mobile station. The radio communication base station device (100) includes: a mapping setting unit (122) which sets a mapping method in a mapping unit (102); the mapping unit (102) which maps a control signal to respective mobile stations to any of subcarriers constituting the OFDM symbol according to the mapping method set by the mapping setting unit (122); an MCS setting unit (121) which references a mapping table in which correlation between a plurality of MCS having different MCS levels and mapping methods is set according to the judgment result of the mapping setting unit (122) and sets MCS in encoding/modulation units (101-1 to 101-n).

Abstract: The invention relates to a new structure of a control channel region within a sub-frame of a 3GPP-based based communication system using OFDM in the downlink. This new structure of a control channel region is inter alia particularly suitable for conveying physical downlink control channel information from a donor eNodeB to a relay node. The control channel region is divided in CCEs that have equal size irrespective of the presence of further cell-specific and/or UE-specific reference signals within the control channel region. This is achieved by dividing the control channel region in plural sub-CCEs that are combined to CCEs all having equal size (in terms of resource elements that can be used for the signaling of control information). The control channel region is divided in the frequency domain and/or time domain in a FDM respectively TDM fashion in order to obtain the sub-CCEs.

Abstract: Wireless communication wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. An encoding operation encodes and outputs transmitting data (bit string) and a bit converting operation converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’. A modulating operation modulates the bit string inputted from the bit converting operation by using a single modulation mapper and a plurality of data symbols are generated.
