摘要： A signal detection method in a TDMA mobile system with co-channel interference and receivers implementing the method. In the method, a primary signal (r.sub.1) and at least one interfering co-channel signal (r.sub.2 -r.sub.N) are received on the same TDMA channel (F.sub.1, TS.sub.3). The co-channel signals propagate through multipath channels (h.sub.L,1 . . . h.sub.L,N) independent of one another, which provide them with a unique wave form coding. In addition, the co-channel signals have different but known training sequences. The multipath channel estimates of the primary signal (r.sub.1) and the at least one interfering co-channel signal (r.sub.2 -r.sub.N) are determined through the received training sequences. After this, the primary signal is detected by utilizing the transmission channel estimates of both the primary signal and the at least one interfering co-channel signal.

摘要： In the overlayed operation of two cellular radio systems one of the two systems is a small-scale or indoor system and the other is a large-scale or outdoor system. The indoor system monitors the operation of the outdoor system and detects, which part of the available radio resources are temporarily not in use in the outdoor system. The indoor system dynamically selects an unused outdoor channel for indoor operation. The indoor radio traffic is divided into cyclically occurring time slots and some of the slots are used for monitoring the existing radio communication on other outdoor channels so that fast changes according to changing traffic and interference conditions are possible.

摘要： A signal for relay is received from a first node. From a local memory that stores K transform matrices (K being an integer greater than one) is selected a transform matrix that is associated with a relay rank order. The matrices define an optimal tradeoff of diversity gain versus spatial multiplexing. The received signal is transformed using the selected transform matrix, and the transformed signal is relayed over a wireless channel to a second node. In a particular embodiment the received signal is an input symbol vector of N consecutive symbols (N being an integer at least equal to two) and the transform linearly combines the N symbols of the input vector according to the relay rank order. In various embodiments the first node may give the rank order, it may be mutually agreed via signaling among the various relay nodes, or it may be based on an intrinsically generated random number.

摘要： Apparatus, methods and computer program products implement a channel-aware approach for controlling a relay network operative in a wireless communications system wherein weighting matrices are used at a MIMO-capable source electronic device and at the relays where at least one of the weighting matrices is selected or derived using knowledge of channel components of at least one channel link, where the channel link may be from the relays to the destination antennas of the destination device; or from source antennas of the MIMO-capable source device to the relays, or from the source antennas of the MIMO-capable source device to the destination antennas of the destination device. In one approach weighting matrices applied at the source and relay nodes are selected from a predetermined codebook of weighting matrices in dependence on monitored channel conditions. Alternatively, the weighting matrices may be determined using an eigenvalue decomposition and power allocation (e.g., water-filling) approach by using the effective channel correlation matrix possibly combined with the use of the noise correlation matrix.

摘要： A wireless node, such as a relay node, has different operating modes for unicast and broadcast/multicast subchannels. For unicast services the phase offsets of those relay nodes engaged in a cooperative transmission are optimized for the subchannels used for unicast services. Alternatively, when no feedback is available and an open loop MIMO or MIMO-type scheme is in use, retransmissions are performed in such a way that a destination (e.g., user terminal) receives effectively a distributed space-time block code. For the broadcast/multicast services time varying random phase offsets may be employed for the subchannels used for broadcast services. For reliable high data rate broadcast transmissions a cooperative retransmission scheme that effectively forms distributed space-time block codes may be used.
