摘要： The method and arrangement according to the present invention relates to of 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 data packets, which composite data packets are transmitted to receiving nodes. Upon receiving a composite data packet the receiving nodes uses their stored a priori information in the process of extracting data for themselves from the composite data packets.

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： Teachings presented herein provide reduced computational complexity and/or memory requirements for a mobile terminal to determine the power backoff required for a multi-carrier uplink signal. In particular, the mobile terminal determines whether its power headroom falls below a pre-defined power headroom threshold, indicating that it is headroom limited. If so, it5 quantizes power allocated to each carrier of the multi-carrier uplink signal according to a pre-defined quantization policy. In doing so, the mobile terminal thereby reduces the possible configurations that may be selected for the multi-carrier uplink signal. Thus, in one embodiment, the mobile terminal stores the required backoff in a look-up table for only the configurations that may be selected when the mobile terminal is headroom limited. This relieves 10 the memory requirements of the mobile terminal as compared to storing the required backoff for all possible configurations of the multi-carrier uplink signal.
摘要翻译：本文提出的教学提供了移动终端降低的计算复杂度和/或存储器要求，以确定多载波上行链路信号所需的功率回退。特别地，移动终端确定其功率余量是否低于预定义的功率余量阈值，指示其净空限制。如果是，则它根据预定义的量化策略量化分配给多载波上行链路信号的每个载波的功率。在这样做时，移动终端因此减少了可能为多载波上行链路信号选择的可能配置。因此，在一个实施例中，移动终端仅在移动终端被限制空间时可以选择的配置在查找表中存储所需的退避。与存储针对多载波上行链路信号的所有可能配置的所需退避相比，这减轻了移动终端的存储器要求。

摘要： The invention describes a flow control method to control HS-DSCH data streams over UTRAN Iub and Iur interfaces. Two credit assignment schemes are also described. A radio network node at which the flow control method executes is proposed. Finally a computer program product for execution of the flow control method and the credit assignment schemes is described. The control of separate user data flows is coordinated by Node-B and data transport over the Iub and Iur interfaces is adapted to data transfer over the Uu interface. The main advantage is that buffering can be primarily maintained in SRNC. It is shown that the proposed flow control method can significantly reduce Node-B's buffer level when compared to a scheme where the control of individual data flows is performed independently of each other. It is also shown that the negative impact on the quantity of flowing data is generally minor.
摘要翻译：本发明描述了一种通过UTRAN Iub和Iur接口来控制HS-DSCH数据流的流控制方法。还描述了两个信用分配方案。提出了流控制方法执行的无线网络节点。最后描述用于执行流控制方法和信用分配方案的计算机程序产品。单独的用户数据流的控制由节点B进行协调，并通过Iub进行数据传输，Iur接口适用于通过Uu接口的数据传输。主要优点是可以在SRNC中主要保持缓冲。结果表明，与单独数据流的控制相互独立执行的方案相比，所提出的流控制方法可以显着降低节点B的缓冲器电平。还表明，流量数据的负面影响通常较小。

摘要： Network node (110) and method (600) in a network node (110), for admission control of an additional radio access bearer based on load of control channel elements on a control channel, assigned by a scheduler (700) comprised in the network node (110). The method (600) comprises assigning (601), by the scheduler (700), control channel elements on the control channel for already admitted radio access bearers. Further, a first and a second load of the control channel is computed (606, 607) based on the usage of assigned control channel elements subframes on which both downlink assignments and uplink grants are enabled, and on which downlink assignments are enabled, respectively. If any of the first or second loads exceeds a respective threshold value, the radio access bearer to be admitted is rejected (609A).
