摘要： Methods and apparatuses are disclosed for determining a muting pattern of a synchronization signal block (SSB) transmission for Integrated Access and Backhaul (IAB) node measurement. In one embodiment, a network node is configured to indicate a first muting pattern, the indication of the first muting pattern indicating at least one first synchronization signal block, SSB, transmission opportunity associated with SSB transmission configuration, STC, that is mutable by an Integrated Access Backhaul, IAB, node. In one embodiment, a network node is configured to determine a first muting pattern, the first muting pattern indicating at least one SSB transmission opportunity associated with a STC that is mutable by the network node; and mute the at least one first SSB transmission opportunity according to the determined first muting pattern.

摘要： A user equipment is configured with at least two collections of uplink resources to be used for transmitting control information to a communication network. The UE receives an assignment of radio resources to be used for receiving a downlink transmission from a base station of the communication network. The UE receives an acknowledgement resource indication, ARI, indicating one of the configured collections of uplink resources to be used for transmitting control information associated with the DL transmission. Further, the UE transmits the control information to the base station on at least a subset of the indicated collection of UL resources. In example embodiments, the indicated collection of uplink resources comprises a plurality of selectable uplink resource sets. The control information is transmitted on one of the uplink resource sets which corresponds to an operational state of the communication network.

摘要： The invention relates to a technique for performing a random access procedure over a radio interface, for example between a mobile terminal and a radio base station of a mobile network. A method aspect of the invention comprises the steps of transmitting a synchronization request for synchronization information; receiving synchronization information in response to the synchronization request; and transmitting, based on at least one transmission parameter adjusted in accordance with the synchronization information, a resource request for data transmission resources.

摘要： There is disclosed a method of operating an Integrated Access and Backhaul (IAB) node in a radio access network, the IAB node being connected to a first parent IAB node via a first backhaul link, the method including communicating with one or more child nodes based on a downlink timing, the downlink timing being based on a function of one or more values of a first timing parameter, the values of the first timing parameter being indicated by corresponding first timing indicators received from the first parent IAB node and/or one or more values of a second timing parameter, the values of the second timing parameter being indicated by corresponding second timing indicators received from the first parent IAB node. The disclosure also pertains to related methods and devices.

摘要： There is disclosed a user equipment for a Radio Access Network. The user equipment is adapted for communicating utilizing a first transmission timing structure having a first number of symbols, and for communicating utilizing a second transmission timing structure comprising a second number of symbols. The user equipment further is adapted for receiving first signaling based on the first transmission timing structure and for transmitting acknowledgement signaling pertaining to the first signaling based on the second transmission timing structure, wherein the user equipment is adapted to start transmitting the acknowledgement signaling at a starting symbol of the second transmission timing structure, the starting symbol being determined based on a configuration of the user equipment.

摘要： A method, performed by a first node (111). The method is for handling access to a communications network (100) in a multi-hop deployment. The first node receives (305), from a fourth node (114), information. The information indicates a recommendation on which node within radio range to connect to, out of a plurality of candidate parent nodes (120). The plurality comprises a first set (121) and a second set (122) of candidate parent nodes. A third node (113) is enabled to be a donor node in the first set (121). A sixth node (116) is enabled to be a donor node in the second set (122). The first node also determines (307), out of the plurality, a second node (112) to establish a connection with. The determining (307) is based on the received information. The first node then initiates (308) establishment of a connection or re-connection to the network via the second node (112), as first-hop.
