摘要： A wireless communication device, WCD, transmits one or more uplink transmissions, obtains backscattering measurements for the one or more uplink transmissions, and reports the backscattering measurements to a wireless communication network. A network node in the wireless communication network receives the backscattering measurements, and estimates an environment of the WCD based on the backscattering measurements. The one or more uplink transmissions may for example include a sounding reference signal, SRS. The network node may for example schedule a transmission, select beamforming, or adapt a positioning reference signal configuration based on the estimated environment of the WCD. The network node may for example receive positioning measurements and estimate a position of the WCD based on the positioning measurements. The estimation of a position of the WCD and the estimation of an environment of the WCD may for example be performed jointly via simultaneous localization and mapping, SLAM.

摘要： A computer-implemented method (1400) performed in a radio access network (1510) for secondary carrier prediction is provided. The method includes obtaining (1402) an uplink channel impulse response based on a reference signal transmitted by a user equipment (UE) (104) over a primary carrier link to a serving network node (102) in a primary cell (102) currently serving the UE (104). The method includes extracting (1404) one or more features from the uplink channel impulse response. The method includes predicting (1406) an existence or non-existence of a secondary carrier link between the UE (104) and a target network node in a secondary cell (106) based on the extracted one or more features. The method includes determining (1408) whether to perform a handover procedure of the UE (104) from the serving network node in the primary cell (102) to the target network node in the secondary network cell (106) based on the predicting.

摘要： The present disclosure provides relates to methods and apparatus for handover optimization in a 5G context using reinforcement learning (RL). In contrast to the conventional handover methods, handovers between base-stations (BSs) are controlled using a centralized RL-based machine learning (ML) agent. This ML agent handles the radio measurement reports from the UEs and chooses appropriate handover actions in accordance with the RL machine learning framework to maximize a long-term utility.

摘要： A computer implemented method for managing radio resources used by UEs in a cellular communication network. The communication network includes a plurality of radio resources, each radio resource defining a dimension of a multidimensional radio space over which the communication network extends. The method is performed by a management node and includes determining that a UE fulfils a location condition with respect to a region of the communication network, and providing to the UE a distributed resource management model for the region of the communication network, the distributed resource management model having a radio coverage model including defining radio characteristics of radio zones in the region. The distributed resource management model is operable for use, by the UE, to identify a radio resource action for execution by the UE. Also disclosed are a method performed by a UE, a management node, a UE and a computer readable storage medium.
