摘要： A method and system for carrier aggregation scheduling in a communication system are disclosed. According to one aspect, a method for carrier aggregation scheduling includes selecting a set of at least one component carrier from a group of candidate component carriers upon which to transmit data in a queue. The selecting of all component carriers in the set is performed prior to determining an amount of data to be assigned to any one of the component carriers in the set. Blocks of data from the queue are assigned to at least one of the component carriers in the set of selected component carriers based at least in part on an estimated amount of data that can be carried by each component carrier in the set.

摘要： A method is disclosed for handling a radio communication of a malicious user equipment, UE, in a wireless communication network. The method is performed by at least one network node in the wireless communication network. The method includes obtaining information identifying the malicious UE attached to the wireless communication network. The method includes performing at least one action to deter or delay serving the malicious UE without terminating the radio communication of the malicious UE with the wireless communication network. Further, the method includes controlling allocation of resources to the malicious UE to allow the malicious UE to retain the radio communication with the wireless communication network. Corresponding network node, and computer program products are also disclosed.

摘要： Methods and systems for dynamically selecting a link adaptation policy, LAP. In some embodiments, the method includes using channel quality information, additional information, and a machine learning, ML, model to select a LAP from a set of predefined LAPs, the set of predefined LAPs comprising a first LAP and a second LAP. In some embodiments, the additional information comprises: neighbor cell information about a second cell served by a second TRP, distance information indicating a distance between a UE and a first TRP, and/or gain information indicating a radio propagation gain between the UE and the serving node. The method further includes the first TRP transmitting data to the UE using the selected LAP.

摘要： A method performed by a network node for managing transmission of Cell Reference Symbols, CRS, wherein the network node 110 operates one or more cells and the network node 110 is configured to transmit the CRS in a first bandwidth mode. When the network node 110 has identified a cell 130 which is not actively serving any UEs 120, also referred to as an empty cell, the network node 110 applies (302) a reduced CRS bandwidth mode in the first cell 130 in relation to the first bandwidth mode. By applying (302) a reduced CRS bandwidth mode in the empty cell 130, the overall interference of the CRS from the empty cell 130 is reduced, thereby enhancing the performance in cells actively serving UEs 120.

摘要： A method for allocating space for a plurality of control sets for Hybrid Automatic Repeat Request (HARQ), wherein each control set comprising elements for carrying HARQ indicators. The method is performed in a network node and comprises determining a largest set size, in number of resources, of any one of the plurality of control sets; determining a target size, in number of resources, to be allocated for HARQ; allocating a HARQ space, wherein the HARQ space having a size, in number of resources, being a maximum of the largest set size and the target size; and spreading the plurality of control sets within the HARQ space. The HARQ space can be used in the uplink, for providing HARQ feedback on downlink information.

摘要： It is presented a method for determining a position of a wireless device, the method being performed in a network node connected to a plurality of remote radio heads via a combiner. The method comprises the steps of: adjusting a weighting of an uplink signal for at least one of the remote radio heads; measuring a signal quality of a combined uplink signal received via the combiner; repeating the steps of adjusting and measuring until an exit condition is true; and determining a position of the wireless device based on how the measured signal quality differs for adjustments of weighting of the uplink signal for different remote radio heads.

摘要： A method for determining whether a radio unit in a shared cell configuration is hearable by a user equipment is provided. Transmission of a probe message to the user equipment by the radio unit is caused. The probe message invokes a probe response from the user equipment if the radio unit is hearable by the user equipment on a downlink channel. The radio unit is hearable by the user equipment if the downlink channel performance between the radio unit and the user equipment meets a predetermined signal criteria. An uplink channel associated with the user equipment is monitored for the probe response from the user equipment after transmission of the probe message. Hearability data associated with the user equipment is determined based on the monitored uplink channel. The hearability data indicates whether the radio unit is hearable by the user equipment the downlink channel.

摘要： According to some embodiments, a method in a wireless device comprises: receiving a control channel (e.g., physical downlink control channel (PDCCH)) that includes control information that indicates a set of time and frequency resources allocated for the wireless device to receive a data transmission; determining that the set of time and frequency resources allocated for data transmission overlaps with a control resource region (e.g., control resource set (CORESET)); and receiving the data transmission in the set of time and frequency resources allocated for data transmission. The control information may include a bitmap that indicates at one or more groups of time and frequency resources excluded/included for the data transmission region.
