    Abstract: According to an example implementation, a method may include transmitting, by a user device to a base station in a wireless network, a system information request for on-demand system information during a random access procedure, where the system information request is a request for one or more parameters that enable the user device to communicate in the wireless network, receiving, by the user device from the base station, an indication of a wait period in which the user device waits before obtaining the on-demand system information, waiting, by the user device, a time duration during the wait period, and monitoring, by the user device after expiration of the wait period, a system information window in which a system information message having the on-demand system information is broadcasted by the base station.

    Abstract: Techniques for performing efficient L1/L2 mobility are provided. For example, a method in a user equipment (UE) connected to a serving cell, is provided. The method comprises receiving, from a first network node, a first reconfiguration message including a first base configuration common to a plurality of first cells served by the first network node and a plurality of first cell-specific configurations each related to one of the plurality of first cells to enable execution of a mobility procedure; and applying, upon execution of the mobility procedure, at least a cell-specific configuration for a first target cell from among the plurality of first cell-specific configurations to connect the UE to the first target cell.

    Abstract: An apparatus, method and computer program is described comprising: obtaining signal measurements from a plurality of antenna panels of a user device at respective first sampling rates corresponding to each of the plurality of antenna panels, wherein a rate at which each of the plurality of antenna panels perform signal measurements is determined based on the respective first sampling rates; determining whether a first condition is satisfied or whether a second condition is satisfied, wherein at least one of the first condition or the second condition relates to a probability of an inbound handover; and increasing at least one of the respective first sampling rates to one or more respective second sampling rates in response to determining that the first condition is satisfied, or decreasing at least one of the first sampling rates to one or more respective third sampling rates in response to determining that the second condition is satisfied.

    Abstract: A method detecting at least one of a mobility failure and a respective successful handover; determining a type of the mobility failure, wherein the type of the mobility failure is determined in response to the detected mobility failure; generating mobility failure information indicative of one or more parameters associated with the type of mobility failure, wherein the mobility failure information is generated, at least in part, based on the determined type of the mobility failure; and providing the mobility failure information and/or successful handover information including, at least in part, one or more parameters associated with the respective successful handover, wherein mobility failure information and/or successful handover information enable a network to determine whether a root cause associated with at least one of a respective mobility failure information and a respective successful handover information is a misconfiguration of one or more parameters controlling L3 handover procedures or L1/2 inter-cell mobility.

    IPC: H04W36/00

    Abstract: A method including receiving, from a second cell, a paging message associated with a network slice supported by a first cell, wherein the paging message includes at least an indication indicating to wait for a command indicative of performing a re-direction or a handover from the second cell to the first cell before transmitting a service request to a network associated with the first cell and the second cell; performing, by the terminal device, the re-direction or the handover from the second cell to the first cell upon receiving the command; and transmitting, through the first cell, the service request upon completing the re-direction or the handover from the second cell to the first cell, wherein the service request indicates a request for establishing a protocol data unit session associated with the network slice.

    Abstract: Systems, methods, apparatuses, and computer program products for a recovery mechanism for single active protocol stack handover. A method may include performing a random access procedure with a target base station. The method may also include receiving, during the random access procedure, a random access response from the target base station. A timer may be started for a predefined duration upon receiving the random access response. The method may further include, when a random access complete message is not sent to a source base station, or a radio resource control connection reconfiguration message is not received from the source base station within the predefined duration, informing the target base station about the failure to send the random access complete message to the source base station, or the failure to receive the radio resource control connection reconfiguration message from the source base station. Handover may be completed to the target base station upon expiration of the timer.
