摘要： A method (1000) for use in a communications system (100, 200, 400), with a first transceiver (110) which transmits data packets to a second (120) and a third transceiver (130). At least the second transceiver (120) can transmit (1010) to the first transceiver (100) a quality value regarding the reception quality of one or more data packets (300) which have been received by the second transceiver, which quality value the first transceiver (110) can use to modify (1015) its data transmissions. The second transmitter (120) listens for data packets intended both for itself and for said third transmitter (130), and the quality value which is transmitted by the second transceiver (120) is based on (1025) the reception quality of one or more of said data packets, and the reception quality value is expressed as (1030) one of a plurality of possible such values.

摘要： User grouping is employed to tradeoff the COMP forward link capacity and required reverse link feedback, which makes the design of COMP practical and flexible. A channel element, such as the large scale fading, is measured for each distributed transmitter and UE pair based on reference signals, and the network receives this information as feedback in the reverse link. The COMP determines a maximum cross interference level αreq that is affordable, based on the available reverse link capacity for feedback. If this maximum cross interference level αreq is exceeded, geographically separate UEs are divided into as few groups as possible, with UEs within each group separated, and the groups are allocated different time/frequency resource blocks. The grouping is done with the constraint that the cross interference does not exceed αreq.

摘要： The invention relates to the control and adaptation of transmit parameters for wireless communication between a transmitter (TX) and at least one receiver (RX) to provide joint power and link adaptation. A basic idea of the invention is to collectively determine the transmit duration (T) and transmit power (P) of the transmitter based on minimization of a given objective function representative of total consumed energy, on both the transmitting side and the receiving side, with respect to transmit duration and/or transmit power. In effect, this means that link transmit parameters are determined based on the energy consumption on both the transmitting side and the receiving side. In addition, both transmit power and transmit duration are varied, while minimizing overall consumed energy.
摘要翻译：本发明涉及用于发射机（TX）和至少一个接收机（RX）之间的无线通信的发射参数的控制和调整，以提供联合功率和链路自适应。本发明的基本思想是基于在发射侧和接收侧上表示总消耗的能量的给定目标函数的最小化来共同地确定发射机的发射持续时间（T）和发射功率（P）关于传输持续时间和/或传输功率。实际上，这意味着基于发送侧和接收侧的能量消耗来确定链路发送参数。此外，传输功率和发射持续时间都是变化的，同时最小化总体消耗的能量。

摘要： A time-frequency resource allocation planner for planning allocation of time-frequency resources to sustain communication links from a common transmitter (TX) to multiple receivers (RX1, . . . , RXK) in a wireless OFDMA communication system includes a resource block selector configured to select a set (RBS) of time-frequency resource blocks (RB) for transmission of one packet for each communication link. A communication link quality measure provider is configured to determine a gain-to-interference-plus-noise ratio measure (Gk) for each communication link. A transmit power and transmit rate estimator, connected to the resource block selector and the communication link quality measure provider, is configured to jointly estimate, within the selected set of time-frequency resource blocks, transmit power (Pk) and transmit rate (Rk) of the packets as functions of determined gain-to-interference-plus-noise ratio measures, to at least approximately minimize expected transmitter energy consumption.

摘要： In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information, with adjacent nodes. In addition distant nodes out of range for direct communication can in accordance with one embodiment be communicated with by forwarding data over multiple hops. The wireless nodes are adapted to perform sensing of at least one radio resource in response to a request from a node. Based on the collective information from at least one other wireless nodes a wireless node can make an improved decision if a particular radio resource is free to use or not.

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.

摘要： The present invention relates to wireless networks using cooperative relaying which in a communication session involve more than one relay station. In the method according to the present invention, a transmitter 210′, a receiver 220′ and at least one relay station 215 are engaged in a communication session. The relay station 215 forwards signals from a first link between the transmitter 210′ and the relay station 215 to a second link between the relay stations 215 and the receiver 220′. The relay station 215 forwards the signal with the use of a relative transmission parameter and optionally a common transmission parameter. The relative transmission parameter is determined locally in each relay station 215 and based on a characterization of a first link, or the second link or a combination of the first and second link.

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.
