    摘要： Disclosed is a data transmission system that transmits data using a relay. During a first time slot, a base station may transmit base station data to the relay, and a mobile station may transmit mobile station data to the relay. During a second time slot, the relay may transmit the mobile station data to the base station, and transmit the base station data to the mobile station.

    摘要： A base station with multiple antennas including a relay scheduler to select a serving relay from a plurality of candidate relays. Each candidate relay may have a user group including at least one user. The selection may be based on an achievable transmission capacity of each candidate relay with respect to its user group and a state of channels formed between the plurality of candidate relays and the base station. The base station also includes a transmission signal generator to generate a transmission signal for the user group corresponding to the serving relay.

    摘要： A technique for setting the transmission powers of individual D2D (device-to-device) transmitters using a distributed power control technique is described. Each individual D2D transmitter learns the interference levels that it imposes on an eNB (evolved Node B) and on D2D receivers other than its partner D2D receiver. The D2D transmitter is then able to adjust its transmission power accordingly. Such managing of interference temperature via distributed power control enables the network to maximize its reuse of time-frequency resources.

    摘要： This disclosure describes methods and devices related to self-interference cancellation. A device is disclosed comprising: at least one memory storing computer-executable instructions; and at least one processor configured to access the at least one memory, wherein the at least one processor may be configured to execute the computer-executable instructions to cause to send at least one first symbol sequence at least twice on a first transmit chain and at least one second symbol sequence twice on a second transmit chain. The processor may be configured to execute the computer-executable instructions to determine at least one third symbol sequence at least twice on a first receive chain and at least one fourth symbol sequence at least twice on a second receive chain. The processor may be configured to execute the computer-executable instructions to determine a first impulse response of a first power amplifier on the first transmit chain and a second impulse response of a second power amplifier on the second transmit chain. The processor may be configured to execute the computer-executable instructions to determine a first aggregate impulse response associated with one or more first devices on the first transmit chain and the first receive chain. The processor may be configured to execute the computer-executable instructions to determine a second aggregate impulse response associated with one or more second devices on the second transmit chain and the second receive chain. The processor may be configured to execute the computer-executable instructions to determine a third impulse response based at least in part on the first and second impulse response, and the first and second aggregate impulse response. The processor may be configured to execute the computer-executable instructions to determine an estimate of the third impulse response based at least in part on the at least one first symbol sequence or the at least one second symbol sequence.

    摘要： Described are techniques for managing the interference produced by D2D (device-to-device) transmissions that may be used in conjunction with transmit power control but operate independently. In one technique, interference between D2D transmissions and cellular uplink transmissions using common resources as received at a base station is managed by opportunistic interference alignment and clustering of D2D devices. In another technique, interference between different D2D devices using the same resources is mitigated by base-station aided space-time interference alignment.
