Abstract:
Systems, methods, apparatuses, and computer program products for user equipment (UE) configuration for accessing at least one cell are provided. For instance, an IAB donor centralized unit (CU) may transmit configuration information for controlling accessing the at least one cell in a dedicated time period in case an operation and management (O&M) or the CU allocates a new physical layer cell identity (PCI) to a IAB-node serving the UE. The message may be directed to UEs served by the IAB-node. In a second scenario, the message may be directed to the mobile terminal (MT) of an IAB node to configure a target parent cell for the case of backhaul radio link failure (RLF).

Various example embodiments relate to signaling and execution of a handover based on an enhanced measurement report. A measurement report comprising an additional information element may be used by a network to make better and urgent decisions concerning handover procedures. Apparatuses, methods, and computer programs are disclosed.
Abstract:
It is provided a method comprising monitoring if a source cell intends performing a radio reconfiguration of a terminal configured with a conditional handover from the source cell to a target cell; determining a determined category among plural predetermined categories; wherein the radio reconfiguration is associated to the determined category; for each category a respective predetermined sequence of one or more operations is defined; the respective predetermined of one of the categories is different from the respective predetermined sequence of another one of the categories; and the method further comprises inhibiting the performing of the radio reconfiguration of the terminal unless the predetermined sequence of one or more operations of the determined category is performed along with the performing of the radio reconfiguration if the source cell intends performing the radio reconfiguration of the terminal.
Abstract:
According to an example embodiment, a method may include determining, by a first base station associated with a first cell based on a synchronization signal block (SSB) configuration indicating one or more resources on which a synchronization signal block (SSB) may be transmitted by a second cell, one or more interference protected resources on which the first cell will reduce interference towards the second cell; and sending, by the first base station associated with the first cell to a second base station associated with the second cell, information identifying the one or more interference protected resources on which the first cell will reduce interference towards the second cell.
Abstract:
It is provided a method, comprising monitoring if a first cell receives one or more scheduling mode indications including a first scheduling mode indication for at least one of a downlink transmission of the first cell and an uplink transmission to the first cell, wherein the first scheduling mode indication comprises forbidding to schedule a respective resource for the at least one of the downlink transmission and the uplink transmission; and the method further comprises forbidding, for the first scheduling mode indication, a scheduler of the first cell to schedule the respective resource for the at least one of the downlink transmission and the uplink transmission if the one or more scheduling mode indications are received.
Abstract:
When a given user equipment (UE) has a plurality K of cells currently serving it, in various embodiments there is an algorithm for triggering the UE to wirelessly send a cell measurement report. The algorithm utilizes a parameter whose value is dependent on the number K of cells currently in the UE's active set. The UE updates K anytime a new cell is added to, or a serving cell is removed from, the UE's active set. In various examples the parameter is an offset that operates such that for adding a new cell increasing values of K make it more difficult to satisfy the algorithm. One example has the offset's value computed using a slope value provided by the network and a default offset value; another has the offset's value computed using maximum and minimum allowable values of both K and the offset which are provided by the network.
Abstract:
A multi-panel mobile apparatus may be configured to perform, periodically during a scan time, downlink quality measurements on a serving cell and on at least one neighboring cell; determine, in a first mode, a first distribution of a scan time between a plurality of antenna panels, based on measurement results of a serving antenna panel on the serving cell; determine, in a second mode, a second distribution of the scan time between a subset of the plurality of antenna panels, based on a first difference between measurement results on the serving cell and measurement results on one or more candidate target cells for a handover procedure; and determine, in a third mode, a third distribution of the scan time between a further subset of the plurality of antenna panels, based on a second difference between measurement results on the serving cell and measurement results on a target cell.

Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of interruption time reduction. The method comprises receiving, at a terminal device and from a centralized network device, a configuration at least indicating that a L1 measurement for cell change is to be reported by the terminal device with an indication of interruption free TA acquisition for a cell associated with the cell change, or per a panel indication of the terminal device; and transmitting, to a distributed network device, a report of the L1 measurement based on the configuration.
Abstract:
There are provided measures for beam failure recovery enhancement. Such measures exemplarily comprise, at a terminal, identifying a beam failure with respect to a radio beam provided by a serving cell of said terminal, and deciding, in response to an identified beam failure, to perform beam failure recovery attempts including at least a first beam failure recovery attempt and a second beam failure recovery attempt with respect to said serving cell of said terminal and at least one non-serving cell of said terminal.
