摘要： Systems and methods are disclosed herein that relate to Dual Connectivity (DC) for a wireless device is a wireless communication network. In some embodiments, a method in a secondary node for providing, along with a master node, DC for a wireless device such that the wireless device is configured to utilize resources provided by both the master node and the secondary node in a wireless communication network is disclosed. The method comprises receiving, from the master node, a release request. The release request is a request to release a wireless device context of the wireless device or to release resources for the wireless device. The method further comprises sending a release reject to the master node. The release reject is an indication that the secondary node rejects the release request.

摘要： A network node (200), a wireless device (202) and methods therein, for decoding of contention based uplink transmissions of data in a cell served by the network node. The network node (200) registers the wireless device (202) for contention based uplink transmissions of data on a radio resource reserved for contention based uplink transmissions of data, e.g. when receiving a registration request sent from the wireless device, such that the wireless device (202) is included in a set (200a) of wireless devices being registered for contention based uplink transmissions of data on the radio resource in the cell. The network node (200) then performs blind decoding of uplink signals transmitted on the radio resource by considering the wireless devices in the set. In this way, the decoding is made more efficient by disregarding any other wireless devices in the cell which are not registered for contention based uplink transmissions of data on the radio resource in the cell.

摘要： A method of a network node of a wireless communication system is disclosed, wherein the wireless communication system is adapted to operate in accordance with a first (system standard) latency requirement comprising a first latency. The method comprises receiving a message from a wireless communication device, the message indicating that the wireless communication device is adapted to transmit data associated with a second latency requirement comprising a second latency which is lower than the first latency. The method also comprises selecting a configuration for the wireless communication device from a plurality of configurations, wherein each configuration is associated with a respective group of wireless communication devices adapted to transmit data associated with the second latency requirement. Each of the plurality of configurations comprises a respective radio resource for potential transmission by the wireless communication devices of the respective group, and the selection is based on a probability of interference between the potential transmissions by the wireless communication devices of the group associated with the selected configuration. The method also comprises transmitting configuration information to the wireless communication device regarding the radio resource of the selected configuration. Corresponding computer program product, arrangement and network node are also disclosed.

摘要： A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

摘要： The present disclosure relates to methods and devices for improved cell detection. In particular the disclosure relates to cell detection within a group of cells with high requirements of low latency. The disclosure also relates to corresponding computer program. The disclosure proposes a method, performed in a wireless device, for cell detection within a group of cells. The method comprises detecting a first synchronization signal of a first cell in the group, wherein the detecting comprises searching for any of a set of predefined synchronization signals. The method further comprises obtaining, based on the detected first synchronization signal, information defining a subset of the predefined synchronization signals, wherein the subset defines synchronization signals that are possible within the group of cells. The method also comprises decoding one or more further synchronization signals of cells in the group of cells using the obtained information.

摘要： A method and a first node (700) for handling a feedback procedure requiring transmission of feedback messages indicating either an acknowledgement, ACK, or a non-acknowledgement, NACK, of correct reception of data transmitted on a forward link in a radio communication with a second node (702) in a radio network. The first node (700) obtains (300) a latency requirement of the radio communication corresponding to the time from transmission of the data until the data becomes outdated. The first node (700) further applies (304) a first transmission mode employing said feedback procedure when the latency requirement is above a latency threshold, and applies (306) a second transmission mode omitting said feed back procedure when the latency requirement is below the latency threshold.
