The method includes: performing a plurality of first operations on a plurality of resources, where the first operation includes at least one of the following: radio link monitoring RLM, beam failure detection BFD, and radio resource management RRM; and performing measurement adjustment for measurement of the first operation in a case that a preset condition is satisfied; where the preset condition is determined based on at least one of the following: measurement results of a plurality of resources and states of the plurality of resources; and the measurement adjustment includes at least one of measurement relaxation, measurement enhancement, and normal measurement.

Systems, methods, and non-transitory media are provided for low latency handovers. An example method can include receiving, by a user terminal associated with a cell served by a satellite, a schedule of communications between the user terminal and one or more satellites; requesting, based on the schedule, a handover from a beam of the satellite to a different beam of one of the satellite or a different satellite; processing packets transmitted over the beam of the satellite and/or the different beam of the one of the satellite or the different satellite; performing the handover from the beam of the satellite to the different beam of the one of the satellite or the different satellite; and after the handover, transmitting, by the user terminal, one or more packets via the different beam of the one of the satellite or the different satellite.

The present application discloses a method and a device in a node for wireless communications. A first node receives a first reference signal group to determine a first-type received quality group; maintains a second counter according to the first-type received quality group; and transmits a first signal. The first signal indicates a first reference signal; when a first counter is no larger than a first threshold, the first reference signal belongs to a first reference signal subset; when the first counter is larger than the first threshold, the first reference signal belongs to a second reference signal subset; a reference signal in the second reference signal subset does not belong to the first reference signal subset; as a response to a first condition set being satisfied, the first signal is triggered. The method above achieves rapid cross-cell beam switch, thus guaranteeing the service quality and avoiding ping-pong effect.

Disclosed is a method comprising transmitting a beam switch request from a first distributed unit to a second distributed unit. The first distributed unit then receives a beam switch acknowledgment from the second distributed unit. The first distributed unit transmits a beam switch notification to a central unit, wherein the first distributed unit and the second distributed unit are at least partly controlled by the central unit. The first distributed unit further transmits a beam switch command to a terminal device.

The method for beam footprint handover performed by a terminal comprises the following steps: receiving a first signaling, wherein the first signaling is used for instructing the terminal to hand over from a first beam footprint to a second beam footprint; handing over from the first beam footprint to the second beam footprint in response to the first signaling; wherein a beam footprint is a coverage range of the downlink beamforming signals, the first beam footprint and the second beam footprint belong to a same cell, and downlink signals in the first beam footprint are transmitted with the first beam, while downlink signals in the second beam footprint are transmitted with the second beam.

Apparatus and methods are provided for TA maintenance and acquisition for mobility with inter-cell beam management. In one novel aspect, the source TAG is maintained with the associated TAT running when cell switch is performed to switch from the source cell to a target cell and skips the RA procedure when a valid target TAG exists. In one embodiment, the target TAG is valid when there is the target TAG exists and a TAT of the target TAG is running. The UE performs a RA to the target when the UE determines that there is no TAG associated with the target or when a TAT of the target TAG expires. The source cell and the target cell belong to the same cell group or different cell group. In one embodiment, the UE performs a partial MAC reset and maintaining a TAT associated with the source cell.
