  • Network node, a wireless device and methods therein for handling automatic repeat requests (ARQ) feedback information
    Patent number: 10469213
    Abstract: Embodiments herein relate to a method performed by a network node (110) in a wireless communications network (100) for handling Automatic Repeat reQuest, ARQ, feedback information from a wireless device (121) relating to downlink transmissions from the network node (110). The network node (110) obtains an indication of a downlink processing delay for the ARQ feedback information from the wireless device (121). Then, the network node (110) considers the ARQ feedback information relating to a downlink transmission from the wireless device (121) to be invalid when, according to the obtained indication of a downlink processing delay, the downlink transmission has not been processed by the wireless device (121). Embodiments of the network node (110) are also described.

  • Identification of potentially neighboring network nodes in a wireless communication network
    Patent number: 10349258
    Abstract: Identification of network nodes (110a-c) of a first Radio Access Technology, “RAT”, and of a wireless communication network (100), which network nodes (110a-c) are at least potentially neighboring each other. Multiple information sets associated with multiple communication devices (120a-c), respectively, are obtained (204a-b; 401). Each communication device (120a-c) supports both the first RAT and another, second RAT. Each information set, thus associated with a communication device (120a), identifies a network node (110a) of the first RAT, and one or more network nodes (111a) of the second RAT that have been identified by the communication device (120a) when the communication device (120a) was associated with a communicative connection to said identified network node (110a) of the first RAT. The network nodes (110a-b) of the first RAT that are at least potentially neighboring each other are then identified (205; 402) based on the obtained multiple information sets.

  • IDENTIFICATION OF NEIGHBORING NETWORK NODES IN A WIRELESS COMMUNICATION NETWORK
    Publication number: 20190208431
    Abstract: Methods, nodes and arrangements for supporting identification of one or more neighboring network nodes comprised in a wireless communication network. A communication device is associated with a communicative connection to a first network node, e.g. a serving base station. The communication device obtains a first identifier identifying the first network node, and transmits the obtained first identifier in an uplink so that the first identifier is receivable by one or more other, second network nodes, e.g. non-serving base stations. Receipt of the first identifier by a second network node enables identification of the first radio network node as neighboring said second radio network node. The second network node obtains, based on the first identifier, an address of the first network node, and/or a second identifier uniquely identifying the first network node, in the wireless communication network.
