Abstract: This invention relates to signaling of resource assignments in cross-carrier scheduling scenarios. In order to enable cross-carrier scheduling in a mobile communication system using carrier aggregation while avoiding erroneous detection of assigned physical resources that could lead to HARQ soft buffer corruption/degradation of the system throughput, the invention suggests a scheme for explicitly indicating within downlink control information (DCI) including a resource assignment for the downlink (or uplink) the number of OFDM symbol(s) used for control signaling within a sub-frame on a component carrier on which resources are assigned by the DCI. In one exemplary implementation the number of OFDM symbol(s) used for control signaling is the PCFICH values signaled in a 3GPP LTE-A network. The indication of the OFDM symbol(s) within the sub-frame on the assigned component carrier may for example be jointly encoded with other control signaling information, e.g.

Abstract: The aim of the present invention is to provide an efficient and reliable transmission/reception mechanisms for a communication system with multiple component carriers, each of which further includes physical resources such as transmission slot/symbol, subcarrier/frequency subband, code, or radiation pattern. Accordingly, the control signal of a component carrier comprises a scheduling assignment specifying for said component carrier a resource for transmission of a data signal, and an allocation map specifying that a scheduling assignment has been sent for another component carrier. Signalizing the allocation map enables detection of possibly missed scheduling assignments.

Abstract: Transmission power control and signaling from a base station to a group of terminals in a system such as LTE supporting carrier aggregation. The transmission power control message has a plurality of transmission control fields of which a multiple is assigned to each terminal. A transmission control field carries a transmission power command for the respective uplink component carrier and the respective mobile terminal. The transmission power control message is mapped to a control signaling region of a downlink component carrier and transmitted within a subframe.

Abstract: The invention relates to methods and apparatuses for providing HARQ feedback in a mobile communication system using carrier aggregation. To suggest a scheme for transmitting feedback on the successful/unsuccessful decoding of transmissions that is operable in FDD mode, the invention proposes to utilize only a single one of plural radio resources available for feedback transmission for signaling feedback for multiple transmissions. A feedback sequence of ACK/NACKs for the transmissions is mapped to one feedback resource combination that is one of the radio resources available for feedback transmission and a modulation symbol of the given modulation scheme that is transmitted on said one radio resource. This scheme can also be used in cases where the number of possible feedback sequences of ACK/NACKs for the transmissions is larger than the number of feedback resource combinations available for feedback transmission.

Abstract: In a mobile communication system with uncorrelated channel characteristics, transmission using modulation of data symbols with repetition can improve the performance. However, mapping of the original and the repeated symbols into the physical resources may on the other hand reduce a desired level of diversity when the original and the corresponding repeated symbols map on the physical resources close to each other. The present invention provides a method for transmission, a transmitter, a method for receiving, and a receiver capable of efficiently transmit/receive data symbols with an increased level of diversity. This is achieved by grouping of portions of the original and the corresponding data symbols and by mapping the portions of the original and the corresponding data symbols into the different physical resource blocks.

Abstract: A system for and method improving order and transaction flow-though and processing. The method may include receiving an order request from a user corresponding to the order. The method may further include determining a set of order particulars associated with the user and the order for resolution against an external system for order fulfillment, and determining if any order particular is incorrect or missing. The method may also include identifying the missing or correct order particular, and updating the set of order particulars to include the missing or correct order particular without requesting missing or correct order particular from the user. The method may include transmitting the updated order particulars to the external system for order fulfillment.

Abstract: The invention relates to a method for determining a retransmission mode of a retransmission protocol for data transmissions provided to a communication terminal. Furthermore, the invention relates to the operation of the communication terminal, e.g. a user equipment or relay node, to perform such method, as well as a Node B cooperating with the communication terminal. The invention is inter alia applicable to a 3GPP LTE-A system as standardized by the 3rd Generation Partnership Project (3GPP). In order to suggest a mechanism for determining or dynamically configuring a retransmission mode of a retransmission protocol, the invention suggests a control message format that allows a dynamic signaling of the retransmission mode of a retransmission protocol. The control message is designed to comprise a field that can indicate a plurality of different codepoints. The codepoints are divided into at least two subsets, wherein the codepoints of each subset indicate a respective retransmission mode.

Abstract: This invention relates to methods for transmitting and receiving transmit power control commands from a base station to a group of mobile terminals in a OFDM based mobile communication system using component carrier aggregation of plural component carriers. Furthermore, the invention also relates to an implementation of these methods in hardware and software. The invention suggests an efficient scheme for signaling transmit power control commands. In one signaling format multiple TPC commands are sent for the uplink component carriers of a mobile terminal in one TPC message. In another signaling format, the TPC commands for the mobile terminal are signaled in respective TPC messages. A further aspect of the invention is the reduction of signaling overhead by signaling carrier group TPC commands that control the transmit power of a group of component carriers. Similarly, an all carrier TPC command is provided to control the transmit power on all uplink component carriers of a mobile terminal.
