    摘要： A method, communication apparatus, and computer program product is provided for mitigating interference experienced by a wireless communication device, WCD (102). The interference is caused by signals transmitted by an interfering node (106). The communication apparatus determines information related to the interfering node (106). The communication apparatus selects, based at least in part on the determined information related to the interfering node (106), a WCD receiver configuration from a set of available WCD receiver configurations. The set of available WCD receiver configurations comprises i) a first WCD receiver configuration that mitigates only interference caused by physical signals transmitted by the interfering node (106) and ii) a second WCD receiver configuration that mitigates only interference caused by physical channels transmitted by the interfering node (106).

    摘要： Systems and methods for triggering interference mitigation at a wireless device in a cellular communications network are disclosed. In one embodiment, a node associated with a cellular communications network makes a determination to trigger interference mitigation at a wireless device based on a signal load in at least one interfering cell from which transmissions result in interference at the wireless device during reception from a desired cell, a relation between reference signals used in the desired cell and the at least one interfering cell, and a timing relation between at least one of a group consisting of: signals transmitted by the desired cell and the at least one interfering cell and signals received at the wireless device from the desired cell and the at least one interfering cell. In response to making the determination, the node triggers interference mitigation at the wireless device.

    摘要： A novel way for transmitting physical signals by a transmitter node (20, 40) based on the LBT principle, and informing a receiver node (30, 50) in cases where the transmission of the physical signals has been deferred or does not occur in a certain time resource, is presented. A transmitter node (20, 40) listens to a wireless radio channel during a first time resource. If there is no activity, or if the activity is below a threshold, the transmitter node (20, 40), in a second time resource, transmits an indicator indicating that one or more physical signals are also transmitted in the second time resource. A receiver node (30, 50) detects if an indicator is present in the time resource. If the receiver node (30, 50) detects the indicator, the receiver node (30, 50) may also receive and use one or more reference signals in the current time resource for doing one or more tasks.

    摘要： A communication device (10, 100-1, 100-2, 100-3, 100-4) detects potentially colliding usage of transmission resources. Further, the communication device (10, 100-1, 100-2, 100-3, 100-4) detects cease of the potentially colliding usage of the transmission resources. After expiry of a backoff time period starting when detecting the cease of the usage of the transmission resources, the communication device (10, 100-1, 100-2, 100-3, 100-4) performs a transmission on the transmission resources. This transmission is performed synchronously with a further transmission on the transmission resources by at least one other communication device (10, 100-1, 100-2, 100-3, 100-4).

    摘要： A transmitting node and a method therein for controlling a transmission rank in a wireless communications system. The wireless communications system comprises the transmitting node and a receiving node. The transmitting node is configured to transmit on multiple antennas according to the transmission rank. The transmitting node allocates one or more first transmission resources between the transmitting node and the receiving node to operate according to a first transmission rank, and one or more second transmission resources between the transmitting node and the receiving node to operate according to a second transmission rank. When a performance of the second transmission rank outperforms a performance of the first transmission rank, the transmitting node configures at least one of the one or more first transmission resources to operate according to the second transmission rank.
