  • Patent number: 8867987
    Abstract: A method for computing a gain control metric used in controlling gain in a wireless repeater operates to store correlation and normalization values associated with the gain control metric for the previous N samples in registers. For each new sample of the gain control input signal, the correlation and normalization values are computed by discarding the multiplication terms of the obsolete sample and adding the multiplication terms of the new sample to the stored correlation and normalization values. In this manner, the complexity of the computation is greatly reduced and the complexity of the computation does not increase with the integration length.

  • Patent number: 8867429
    Abstract: Plural repeaters (1111 to 111n) are connected one another via a system bus (115), and each of which detects the state of another repeater by checking a signal transmitted over the system bus (115). When stopping the operation of home repeater (e.g., the repeater (1111)) which performs relaying process among wireless terminal devices (TA) to (TH), a secondary repeater (e.g., the repeater (1112)) set beforehand detects that the home repeater breaks down as the secondary repeater becomes unable to detect the signal over the system bus (115). The secondary repeater responds to the detection and bears the relaying process instead of the home repeater.

    Abstract: The present invention relates to methods and arrangements that enable easy integration of on/off repeaters in a radio access network and a minimized signaling for the UE repeater selection. This is achieved by a solution where the RBSs are working in a pre-coding mode and where the repeaters are measuring the downlink reference signals, selecting pre-coding matrices and feeding the index of selection back (i.e. the PMI) to the RBS, in analogy with what a UE does. This allows the RBS to distinguish the UE repeater selection, without introducing any extra uplink report or interaction between UEs and repeaters, by comparing the index from the UE with the indices from different repeaters.

  • Patent number: 8798525
    Abstract: A relay node (800) reports its output power capability to a donor base station or other network node separately for the relay node's backhaul and access links, which may have different maximum output power. A corresponding network node (900), such as a donor base station, an Operations & Maintenance node, an Operational Support Systems node, a Self-Organizing Network node, is configured to request the relay node (800) to report its backhaul link and access link output power class capabilities or maximum output powers or rated output powers to the network node (900), and then to receive the reported capabilities in response. The report may specify a per-antenna transmit power capability; this may be specifically requested in some cases. The received relay node power-class capability information for the backhaul and access links is then used for one or several network management functions, such as radio resources management or network planning and dimensioning.

  • Patent number: 8792367
    Abstract: Cooperative communication is a technique that can be employed to meet the increased throughput needs of next generation WiMAX systems. In a cooperative scenario, multiple stations can jointly emulate the antenna elements of a multi-input multi-output system in a distributed fashion. A framework for a randomized distributed space-time coding (“R-DSTC”) technique in the emerging relay-assisted WiMAX network, and the development of a cooperative medium access control (“MAC”) layer protocol, called CoopMAX, for R-DSTC deployment in an IEEE 802.16 system, is described. The technique described couples the MAC layer with the physical (PHY) layer for performance optimization. The PHY layer yields significant diversity gain, while the MAC layer achieves a substantial end-to-end throughput gain.

  • Patent number: RE45125
    Abstract: A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MS2, the RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilot 2 for reproduction relay, and the line quality (the line quality between the MS2 and the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS2 (a mobile station (2)) through the RS. The MS2 encodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS.
