    摘要: The invention relates to a message for reporting a channel quality of a communication system, a corresponding method and apparatuses performing such method. The invention is inter alia applicable to a 3GPP LTE and LTE-A system as standardized by the 3rd Generation Partnership Project (3GPP). The invention provides a structure (message) that allows conveying channel quality information in a manner allowing an unambiguous identification of the size channel quality information. This is achieved by defining a message comprising a first channel quality field consisting of a known number of bits, and a second channel quality field consisting of a variable number of bits. The number of bits and structure (of the content of the bits) of the second channel quality field is indicated by the content of the bits of the first channel quality field.

    摘要: 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.

    摘要: This invention concerns concepts for signaling resource allocation information to a terminal that indicates to the terminal assigned resources for the terminal. The terminal can receives downlink control information (DCI), which comprises a field for indicating the resource allocation information of the terminal. This resource assignment field within the DCI has a predetermined number of bits. The terminal can determines its assigned resource allocation information from the content of the received DCI, even though the bit size of the resource allocation field in the received DCI is insufficient to represent all allowed resource allocations. According to an embodiment, the received bits that are signaled to the terminal in the DCI represent predetermined bits of the resource allocation information. All remaining one or more bits of the resource allocation information that are not included in the field of the received DCI are set to predetermined value.

    摘要: The invention relates to a method for transmitting data packets between an eNodeB and a mobile node (MN) when simultaneously using the HARQ protocol with soft-combining for unicast and multicast transmissions. Unicast transmissions are assigned to HARQ processes by the eNB, whereas multicast transmissions need to be assigned to a HARQ process by the MN. According to a first aspect, the soft-buffer memory is strictly separated into a unicast and multicast section, and HARQ protocol operations for unicast and multicast are independent. Due to the separation, the eNB can still correctly assign the unicast transmissions to a HARQ process. According to a second aspect, the soft-buffer is not separated but commonly used for unicast and multicast. However, in order for the eNB to still be able to correctly assign the unicast transmissions to a free HARQ process, the MN assigns the multicast transmission depending on a rule, known also to the eNB.

    摘要: The invention relates to methods for detecting at least one of a downlink grant and an uplink grant within a sub-frame of an OFDM-based mobile communication system. The invention provides a reception apparatus (e.g. a relay node or a mobile terminal) that are adapted to perform these methods. The invention defines the uplink grant search space to form a subset of the downlink grant search space. In other words, in the frequency domain, the uplink grant search space is defined on a subset of the resource block pairs that form the downlink search space. This configuration allows downlink data to be mapped to the remaining resources outside the uplink grants search space and the resources used for a downlink grant. Furthermore, the downlink grants comprise an indication of whether the uplink grant search space in the sub-frame comprises (user) data or not.

    摘要: 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.

    摘要: The invention relates to a downlink transmission scheme that supports downlink HARQ operation and macro-diversity that is capable of overcoming the problem of HARQ protocol de-synchronization when using HARQ in the downlink with multiple data transmitting network nodes. In this scheme, a distributed HARQ protocol operation for downlink data transmissions involving multiple network nodes is provided, where only one network node is terminating downlink HARQ protocol operation towards to mobile terminal, i.e. retransmissions of a data packet are sent from a single network node, a single HARQ transmitter, to the mobile terminal. The multiple network nodes send a first transmission of the data packet to the mobile terminal in a single transmission time interval using HARQ. One of the multiple network nodes is designated as the HARQ terminating node that controls/handles all retransmissions of the data packet.
