摘要： Systems and methods for landscape sensing using radio signals are provided. In some embodiments, a base station configured to communicate with a User Equipment (UE) comprises a radio interface and processing circuitry configured to: obtain a plurality of channel measurements relating to the UE; and determine a landscape type in which the UE is operating based on the plurality of channel measurements. In this way, the base station can infer the UE's landscape without the need for any new sensor or radar infrastructure requirements. In this way, the signaling need between BSs can be reduced. In some embodiments, smaller dimension input features will reduce the computational complexity so that it can be implemented on an embedded BS hardware.

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： Embodiments include methods for downlink (DL) transmission by a network node in an integrated access backhaul (IAB) network. Such methods include receiving, from an upstream node in the network, first timing offset information related to communications between the network node and the upstream node. Such methods include transmitting a DL signal or channel, to one or more downstream nodes, based on a DL transmission timing for the network node. The DL transmission timing is determined from the network node's DL reception timing of signals or channels transmitted by the upstream node and a second function of the first timing offset information, which is determined based on a first function of the first timing offset information (when the first function is greater than a threshold) or on an alternate timing offset (when the first function is not greater than the threshold). Embodiments also include network nodes configured to perform such methods.

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.

The User Equipment receives, from a network node (160), an indication of a measurement object, MO, pointing to a frequency location of a primary SSB. The UE (120) further performs measurements on the primary SSB based on the indicated MO. Embodiments herein further relate to a method, performed by a network node (160), for handling RRM measurements for the UE (200), on a carrier comprising a plurality of SSBs. The network node (160) determines a primary SSB out of the plurality of SSBs on the carrier. The network node (160) further sends, to the UE (200), an indication of a MO pointing to a frequency location of the primary SSB.
