摘要： Methods and apparatuses for enabling frequency selective repetition of signals in a telecommunication system in which aggregation of component carriers is applied. Information signals are received (1102) in a first set of frequency bands, which is defined to cover anchor carriers, which can be used by both legacy and non-legacy terminals. Further, information is received (1104) in a second set of frequency bands, which is defined to cover non-anchor carriers, which only can be used by non-legacy terminals. Instructions concerning which frequency band(s) that should be repeated by the repeater node, are also received (1106). Thereafter, the frequency bands indicated in the instructions are filtered out (1110), after which these frequency bands or parts are repeated by the repeater node. This results in enabling frequency selective repetition in a system which may comprise legacy mobile, which limits the interference in the system, which enables higher bitrates and saves energy.

摘要： In a multihop communications network a cost determination method includes determining a plurality of simultaneously potential or favorable next hop nodes for at least one of the nodes between a source and a destination node pair, whereby a mesh-like path comprising a plurality of simultaneously potential routes or paths is defined between the source and destination node. This mesh-like structure is typically determined in a distributed manner and results from a cost optimization process. The cost optimization should preferably consider stochastic variations that for example are caused by the wireless medium.

摘要： Each receiving node (120) of a plurality of receiving nodes (120-1, 120-2 and 120-3) such as base stations in a wireless network converts a superposition of signals received from a plurality of transmitting nodes such as mobile terminals (10) to produce soft complex signal information. The soft complex signal information associated with the considered plurality of receiving nodes are collected, for example in a central node (130) and jointly detect signal information transmitted from at least a subset of the plurality of transmitting nodes (10) based on the collected soft complex signal information. The collected soft signal information generally retains phase and amplitude information, and the transmitted signals are preferably detected in a joint detection process based on a complex channel representation and collected soft signal information. In a truly distributed realization, adjacent receiving nodes or base stations exchange soft complex signal information with each other, thus forming at least partially overlapping groups for distributed collection of information, detection and subsequent decoding in each base station.

摘要： The present invention relates to methods and arrangements in a relaying radio node and/or in a sending/receiving radio node, adapted for use in a relaying communication system. The relaying node is in bidirectional communication with at least a first and a second sending/receiving radio node, and the relaying radio node receives at least a first signal carrying at least first data and a second signal carrying at least second data. The relaying node generates a reduced representation of at least the first and second signal, with a reduced information content as compared to the first and second data, by a joint non-linearly encoding operation, and transmits the reduced representation to at least the first and the second communication node. The first and second sending/receiving node can extract data from the reduced representation by a non-linear decoding operation using stored a priori information.

摘要： A wireless relaying network having a number of network nodes including a designated originating node, at least one relaying node, and at least two receiving nodes. The designated originating node transmits a pilot signal, and the relaying node(s) receives and forwards the pilot signal to the receiving nodes, each of which measures channel quality based on the received pilot signal. At least part of the receiving nodes feed information on the measured channel quality all the way back to the designated originating node, and the originating node then schedules data for transmission to at least one selected node of the receiving nodes based on the received channel quality information. Subsequently, the designated originating node transmits data to the selected receiving node(s) via the same relaying node(s) that forwarded the pilot signal. In this way, multi-user diversity scheduling is introduced to relaying networks that provides significant data rate enhancements.

摘要： The method and arrangement according to the present invention relates to scheduling and coding in communication systems utilizing automatic repeat request (ARQ) and/or multihop scheduling and forwarding. According to the inventive method the receiving nodes selectively stores received information, also overheard information, as a priori information and feed back information about their respective stored a priori information to a sending node. The sending node forms composite data packets by jointly encoding and scheduling multiple multicast data packets, and subsequently transmits the composite data packets to the receiving nodes. Upon receiving a composite data packet the receiving nodes uses their stored a priori information, comprising of regular multicast packets, or full or partly decoded composite packets comprised of regular multicast packets, in the process of extracting multicast data packets from the composite data packets.
