摘要： A method for evaluating cell quality includes obtaining cell quality information and determining, based on the cell quality information, a first number, X, of beams whose qualities are above a threshold, T, for a first cell and a second number, Y, of beams whose qualities are above the threshold, T, for a second cell. The method includes complementing a third number, M, of fictive beams to offset a difference between the first number, X, of beams and the second number, Y, of beams, and measuring a first average beam quality, Q 1 , for the first cell and a second average beam quality, Q 2 , for the second cell. The method may include a certain number fictive beams with assigned beam quality when calculating cell qualities for cells which are included in comparison.

摘要： The present disclosure relates to methods and arrangements in a private address resolving node of a personal area network deploying Bluetooth low energy, BLE and in particular to methods and arrangements for proactively resolving periodically updated private addresses. When performed in a private address resolving node of a personal area network deploying Bluetooth low energy, BLE, a method comprises resolving a periodically updated private address of a private address generating node connected to the private address resolving node. The private address is used in addressing messages from the private address resolving node to the private address generating nodes. The method comprises receiving (S41), from a private address generating node in the personal area network, an Identity Resolving Key, IRK, the IRK being received over an encrypted link established between the private address resolving node and the private address generating node and receiving (S43), from the private address generating node, private address update information defining when and how to update the private address of the private address generating node. Based on the received IRK and the received private address update information, an updated private address to be used when addressing a next message to the private address generating node is determined (S45).

摘要： A user equipment (UE) operates to select and/or re-select among radio cells provided by access nodes of a wireless communication system. The UE measures quality of beams detected from each of the cells. For each of the cells, the UE derives cell quality based on the quality of the beams from the cell. For each of the cells, the UE determines the number of good beams among the beams from the cell based on a cell quality threshold received via system information. The UE ranks the cells in a ranking list relative to each other based on the number of good beams associated with respective ones of the cells and the cell quality. The UE controls, based on the ranking of the cells in the ranking list and based on conditions of the number of good beams and the cell quality, selection and/or re-selection of a cell among the cells that is to be used for UE radio communications.

摘要： Method performed by a first node (111) in a Bluetooth Mesh network. The first node (111) generates (501) a first address and/or a first key, which enable any node in the 5 network to determine whether or not a message belongs to the network by inspecting an advertising address in the message. The advertising address is based on the first address and/or the first key. The first address and/or the first key also enable any node in the network to, after a primary advertising extension indication on a primary advertising channel is detected, only tune to a secondary advertising channel associated with the 10 primary advertising channel, when the advertising address comprised in the received message matches the first address and/or the first key. The first node (111) then provides (502) the generated first address and/or the first key to a second node (112) in the network.
