Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of mitigation of performance degradation for improved system performance. The method comprises determining receive timing difference between a serving cell of the first device and a target cell, the serving cell being located on a first carrier, the target cell being located in a second carrier; and determining to report an indication associated with the receive timing difference to the second device. In this way, the network may be aware of experience performance degradation of the UE due to a large RTD without increasing the network complexity. Meanwhile, the TP performance of the UE may be improved.

Abstract: Example embodiments of the present disclosure relate to timing adjustment for uplink transmission, particularly in a high-speed scenario. A first device receives, from a second device, offset information indicating a difference in propagation delays between the first device and a third device experienced by the second device. The offset information is determined based on a time shifting value for a range of the difference in propagation delays. The time shifting value is associated with a switch from a beam associated with the first device to a beam associated with the third device. The third device is different from the first device. The first device transmits, to the second device, timing information indicating an amount of timing advance for transmission from the second device to the third device. The timing information is determined based on the time shifting value. Through this solution. UL transmission will be timing aligned.

Abstract: Systems, methods, apparatuses, and computer program products for enhanced handling time alignment timer at transmission configuration indicator state switch are provided. For example, a method can include performing a transmission configuration indicator state switch to a network element. The method can also include determining whether an uplink timing is aligned with respect to the network element. The method can further include determining whether a random access channel procedure is needed to adjust uplink timing in response to the determining that the uplink timing is not aligned. The method can additionally include adjusting the uplink transmit timing in response to a result of the determining whether random access channel procedure is needed to adjust uplink timing.

Abstract: Systems, methods, apparatuses, and computer program products for beam tracking to reduce latency. A method may include receiving from a network node, a radio resource control reconfiguration message. The method may also include sending a radio resource control reconfiguration complete message in response to the radio resource control reconfiguration message. The method may further include performing radio resource management measurements according to information contained in the radio resource control reconfiguration message. In addition, the method may include preparing a measurement report based on the radio resource management measurements. Further, the method may include sending the measurement report to the network node. The method may also include maintaining a spatial relation with a cell or a carrier that is identified in the measurement report, as indicated in the radio resource control reconfiguration message.
