摘要： A first communication device 100 is configured for device-to-device (D2D) communications with a second communication device 102. A method by the first communication device 100 includes obtaining 300 information on duplex configuration of a radio network node 110 that may affect resource allocation by the first communication device 100 for D2D communication with the second communication device 102. The method further includes deriving 302 a set of resource patterns (RPTs) based on the information, selecting 304 one RPT among the set of RPTs based on scheduler information, and signaling 306 an index that is used to identify the selected RPT to the second communication device 102. Related methods by a communication device to derive resources to be used for D2D reception from another communication device based on a selected RPT are disclosed.

摘要： A method in a communication device for controlling beam-forming (BF) tracking is disclosed. The method comprises switching the communication device from a coarse BF tracking state to a non-BF tracking state when a first timer expires. The communication device transmits pilot signals for BF tracking, feedback information for BF tracking or both the pilot signals and the feedback information more frequently in the coarse BF tracking state than in the non-BF tracking state. Additionally or alternatively, the method comprises switching the communication device from a fine BF tracking state to a coarse BF tracking state or a non-BF tracking state when a second timer expires. The communication device transmits pilot signals for BF tracking, feedback information for BF tracking or both the pilot signals and the feedback information more frequently in the fine BF tracking state than in the coarse BF tracking state.

摘要： The present disclosure relates to a method used in a cluster manager controlling a cluster for a terminal device served by a radio node, and to the associated cluster manager. The cluster manager is under control of a control node and the cluster includes the radio node. The method includes: receiving Layer 1 (L1)/Layer 2 (L2) measurements of the terminal device on the radio node and one or more neighboring radio nodes of the radio node; determining a target radio node, to which the terminal device is to be handed over, based on the L1/L2 measurements; determining whether the target radio node is within the cluster; and if it is determined that the target radio node is within the cluster, determining whether the terminal device is to perform handover from a beam of the radio node to a beam of the target radio node.
