摘要： Methods and apparatuses are disclosed for a closed-loop remote interference management framework. In one embodiment for a victim node, a method includes determining one of at least two messages corresponding to a closed-loop feedback for remote interference mitigation, the at least two messages comprising a first message and a second message, the first message providing a positive mitigation indication and the second message providing a negative mitigation indication, and transmitting the determined one of the at least two messages to another network node. In another embodiment for an aggressor node, a method includes receiving one of at least two messages corresponding to a closed-loop feedback for remote interference mitigation, and taking a remote interference mitigation action based on the received one of at least two messages.

摘要： A method, wireless device and network node for determining a format of downlink control information (DCI) are disclosed. According to one aspect, a network node selects a format of a DCI message from a set of at least two DCI message formats based on one or more of a service type provided to the wireless device, a characteristic of a physical downlink control channel, and a measure of channel quality. The network node signals the DCI message of the selected format to the wireless device . . . . According to another aspect, a wireless device WD determines a format of the DCI message and decodes the DCI message based on the determined format of the DCI message.

摘要： A method for interference coordination comprises receiving, from a first network node, a reference signal indicating that one or more second network nodes are experiencing interference. The reference signal indicates at least one identifier for the first network node and for the second network nodes. The method further comprises preparing a remote interference management (RIM) coordination message based on the reference signal, and sending, to the first network node, the RIM coordination message to be forwarded to the second network nodes. The method provides a communication between a central aggressor network node and a central victim network node to exchange reference signal and RIM coordination information. Furthermore, the central victim network node may pass the RIM coordination message to a group of victim network nodes indicated in the RIM coordination message.

摘要： Methods and apparatuses are disclosed for minimization of network node to network node interference in Time Division Duplex (TDD) network. According to one embodiment, a method in a network node for re-mote interference management includes receiving information indicating a position for a reference signal within a communication signal slot, the position being indicated being indicated relative to a reference point associated with a downlink-to-uplink switch; at least one of transmitting the reference signal and receiving the reference signal based at least in part on the received information; and determining whether remote interference is present based at least in part on at least one of the received reference signal and the received information indicating the position of the reference signal.

摘要： According to some embodiments, a method performed by a wireless device operating in reliable mode comprises obtaining an indication of a subset of all possible control format indicator (CFI) and physical downlink control channel (PDCCH) combinations for the 5 wireless device to search to locate a PDCCH and locating the PDCCH by searching one or more of the subset of possible CFI and PDCCH combinations. Obtaining the indication may comprise receiving radio resource control (RRC) signaling that includes a CFI value. The RRC signaling may include an indication of whether a radio frame pattern is slot or subframe pattern, and the CFI value may be dependent on the radio frame pattern.

摘要： A network node is provided. The network node includes circuitry configured to determine a Transmission Time Interval, TTI, configuration, the TTI configuration including a first TTI for operating a first signal between a first cell on a first carrier and a wireless device, and a second TTI for operating a second signal between the first cell on the first carrier and the wireless device, the TTI configuration including one of: the first TTI adjacent to the second TTI which do not overlap with each other in time; and the first TTI adjacent to the second TTI which at least partly overlap with each other in time, and configured to receive the first signal in the first TTI and the second signal in the second TTI, the first TTI and second TTI having been transmitted based on a maximum output power parameter that is based on the TTI configuration.

摘要： A method by a transmitting node for adapting a transmission mode based on a capability of a receiving node includes obtaining information indicating a capability of the receiving node to receive signals having a certain level of distortion. The transmitting node transmits a signal to the receiving node, the signal transmitted using a transmission mode selected based on the capability of the receiving node.

摘要： Embodiments of the disclosed techniques include methods for remote interference management (RIM) implemented in a network device in charge of management in a wireless network. In one embodiment, a method includes receiving messages from a set of base stations, wherein each message from abase station of the set of base stations indicates that the base station is interfered. The method further includes grouping the set of base stations into a set of reference signal groups based on the messages, each reference signal group being mapped to a reference signal group identifier; and the method continues with sending a respectively mapped reference signal group identifier to each of the set of base stations. Embodiments of the invention also include methods to group base stations causing the interference.

摘要： Methods, network nodes and wireless devices configured for resource allocation to a wireless device are disclosed. According to one aspect, a method includes selecting at least one of a common bandwidth scheme and a common power scheme. If the selected at least one scheme includes a common bandwidth scheme, a common bandwidth to be used by the wireless device for transmission of two data channels in two successive short transmission time intervals, sTTIs, that share a common demodulation reference signal, DMRS, is determined. An indication of the common bandwidth to the wireless device to enable the wireless device to set the bandwidth of the two data channels to a common bandwidth value is sent. If the selected at least one scheme includes a common power scheme, then a common power control command to control an output power to be set by the wireless device for two data channels in two successive sTTI, that share a common DMRS is determined. The common power control command to the wireless device to enable the wireless device to set the output power of the two data channels to a common power value is sent.

摘要： According to some embodiments, a network node in a frequency division duplex (FDD) wireless communication network is operable to schedule a first downlink transmission with a first transmission processing time on a first frequency carrier. The scheduling comprises a first downlink assignment index (DAI). The first DAI comprises a first total DAI and a first accumulative DAI. The network node is operable to schedule a second downlink transmission with a second transmission processing time different than the first on a second frequency carrier. The scheduling comprises a second DAI. The second DAI comprises a second total DAI and a second accumulative DAI. The network node expects hybrid automatic repeat request (HARQ) feedback for the first downlink transmission and the second downlink transmission in a single uplink transmission. The network node is further to transmit the scheduling for the first and second downlink transmission to a wireless device.
