摘要: A system (300) of a wireless communication network (100) comprising a first network node (110) arranged for wireless communication with a wireless communication device (130). A message is triggered to be sent from the first network node (110) to and received by the wireless communication device (130). The message comprises instructions related to measurements by the wireless communication device (130) on a signal from a network node (110; 120) of the wireless communication network (100). The instructions comprising a first measurement condition and a second measurement condition and that both the first measurement condition and the second measurement condition have to be fulfilled for the wireless communication device (130) to report at least one of the measurements to the wireless communication network (100).

摘要: In some embodiments, a network node (e.g., a base station) collects information pertaining to components that form a Maximum Received Timing Difference (MRTD). For instance, the network node determines TAE. The network node then evaluates, for a particular UE, whether a certain MRTD requirement (MRTDR) for a specific coordinated service (CS) can be fulfilled. If the requirement can be met, then the network node may initiate the specific CS for the UE (or continue providing the CS), and if the requirement cannot be met, then the network node may stop or modify the CS for the UE.

摘要: According to certain embodiments, a method for allocating TEIDs by a CU-CP of a network node includes receiving, from a CU-UP, at least one uplink TEID (UL TEID) associated with a DRB. The at least one UL TEID is sent to a distributed unit (DU). At least one downlink TEID (DL TEID) associated with the DRB is received from the DU. The at least one DL TEID associated with the DRB is then sent to the CU-UP.

摘要: A method for arranging transmission of SSBs comprises transmitting (S1), from a first TRXP of a cellular telecommunication system, of first SSBs at a carrier. The first SSBs define a first cell. The first cell is unique for the first 5TRXP. The method further comprises transmitting (S2), from the first TRXP, of second SSBs at the carrier. The second SSBs define a second cell. The second cell is a combined cell of the first TRXP and at least one neighbouring, second TRXP. A method for cell assignment based on multiple SSBs is also disclosed, as well as TRXPs and network nodes for implementing the methods.

摘要: Some embodiments herein relate to a method performed by a wireless communication device for managing communication in a wireless communications network. The wireless communication device obtains an indicator indicating a model and one or more trained model parameters for the model, wherein the model is related to an event being one of the following events: a handover procedure, a cell reselection procedure, and a beam reselection procedure. The wireless communication device further selects the model based on the obtained indicator. The wireless communication device executes the selected model using the obtained one or more trained model parameters; and triggers a process, being associated with the event, based on an output of the executed model.

摘要: A method performed by a network node for managing power of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first power mode. When the network node identifies a first cell which is not actively serving any UEs, which cell is also referred to as an empty cell, the network node reduces the power of the CRS in the first cell in relation to the first power mode. By reducing the power of the CRS, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.

摘要: A method is disclosed performed by a first network node (110) of a wireless communication system (100) for handling of a UE (150) connected to the first network node (110), wherein a second network node (120) of the communication system (100) has a first transmission resource (130) for wireless transmission using a first access technology and a second transmission resource (140) for wireless transmission using a second access technology. The first and the second transmission resources (130, 140) are collocated. The method comprises receiving, from the UE (150), an indication of fulfilled transmission condition for transmission from the second transmission resource (140) to the UE (150), the indication being based on a transmission quality measurement performed by the UE (150) on a wireless signal transmitted by the first transmission resource (130), and determining whether the UE (150) is to be served by the second access technology transmission resource (140) of the second network node (120). The method further comprises, sending, based on the result of the determining, an instruction to the UE (150) to prepare for receiving data in a carrier bandwidth of the second access technology, and sending an instruction to the second network node (120) to prepare for transmitting data from the second access technology transmission resource (140) at the carrier bandwidth of the second access technology.

摘要: In a method for adapting a mobile network, a terminal is connected to a first access node of the mobile network via a first connection and to a second access node via a second connection. The first access node controls a data transmission for the terminal and the second access node assists in the data transmission for the terminal. The method comprises determining whether a quality of at least one of the first connection and the second connection is degraded, acquiring quality degradation information about the degradation of the quality of at least one of the first connection and the second connection based on the step of determining, and adapting the mobile network based on the step of acquiring.
