摘要： There is provided mechanisms for assist cell selection or reselection in a relay-assisted wireless network. A method is performed by a network node. The method comprises providing, towards a user equipment that has an end-to-end wireless link composed of a wireless access link and at least one wireless backhaul link between itself and a donor node of the relay-assisted wireless network, backhaul link characteristics of the at least one wireless backhaul link. The backhaul link characteristics assist the user equipment to derive an end-to-end wireless link quality metric for the end-to-end wireless link when performing a cell selection or a reselection procedure.

摘要： For contention free random access (CFRA) with 2-step RA type or 4-step RA type, a network node may configure different physical random access preamble configurations (e.g., different PRACH occasions, preamble index, or preamble format) for different user equipment (UE)/service groups that are associated with different UE priorities, UE types, service priorities, service types, and/or network slices. A UE may select a configuration to use to transmit the random access preamble based on the priority of the UE, the type of the UE, the priority of the service, the type of the service, and/or the network slice. In 2-step RACH, a network node may also configure different msgA PUSCH resources for different UE priorities, UE types, service priorities, service types, and/or network slices.

摘要： There is provided mechanisms for adaptive cell-shaping in a cellular network in which a group of radio access network nodes provide network access. A method is performed by a network node. The method comprises obtaining an indication of combined network performance degradation in a region in which a first radio access network node in the group of radio access network nodes provides network access and increased need for network access for prioritized service and/or prioritized subscribers in this region. The method comprises initiating adjustment of cell- shaping parameters of at least one radio access network node in the group of radio access network nodes. Network access for the prioritized service and/or prioritized subscribers in the region is maintained by this at least one radio access network node in the group of radio access network nodes.

摘要： In wireless device-to-device, D2D, communication data (D) are transmitted directly from a first wireless device (UE Tx) to a second wireless device (UE Rx). In response to the direct transmission of data (D), the second wireless device (UE Rx) transmits feedback data (FB1, FB2) indicating at least one quality of the data (D) received in the second wireless device (UE Rx). More precisely, according to the invention, a radio access network node (BS) controls the direct transmission of data (D) by means 10 of downlink control information (Ctrl1, Ctrl2) to the first and second wireless devices (UE Tx; UE Rx), and the feedback data (FB1, FB2) are received in the radio access network node (BS). The radio access network node (BS) preferably also uses the received feedback (FB1, FB2) to control at least one of the first and second wireless devices (UE Tx; UE Rx).

摘要： It is presented a method performed by a network node of a wireless communication network for scheduling a wireless device in uplink. An uplink signal structure is configured to be used by the wireless device and the network node, wherein the uplink signal structure defines transmission subframes divided into symbol periods. The network node applies a short Transmission Time Interval, sTTI, scheduling interval, wherein each sTTI is shorter in time than a subframe and each sTTI comprises at least one symbol period. The method comprises: transmitting a control information message to the wireless device for an sTTI scheduling interval, the control information message comprising uplink scheduling information assigned to the wireless device, the uplink scheduling information indicating a position and a length for at least one of a reference signal and data in the uplink sTTI.

摘要： Embodiments of the present disclosure provide methods and apparatus for deploying movable base station. The method comprises: collecting (S102), by a data collection module, data about measurements and/or performance metrics relating to at least one terminal device to be served by at least one movable base station; determining (S104), by a model inference module, configuration for deploying the at least one movable base station, based on at least part of the collected data; actuating (S106), by an actor module, the at least one movable base station, based on at least the determined configuration. The determined configuration optimizes at least one of the performances metrics at the at least one terminal device, which may be better than performances metrics when the at least one terminal device is served by the network node. Therefore, a proper decision on the deployment and configuration of the movable base station may be made.
