Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a cell from a base station. In some examples, the cell may be deactivated and the base station may configure the cell with one or more base station beams. The UE may receive beam management resources for performing beam management based on the configured base station beams. In some examples, the beam management resources include resources for transmitting or receiving one or more reports indicating a quality of the configured base station beams. The UE may then perform the beam management, while the cell is deactivated, to track one or more UE beams corresponding to the configured base station beams.

Embodiments of the present disclosure provide a scheduling method and a base station. In a cell handover process, a target base station serving a target cell receives a random access request from a terminal, sends a random access response to the terminal according to the random access request, and proactively sends an uplink grant to the terminal after sending the random access response and prior to receiving a handover complete command from the terminal. By proactively sending the uplink grant, the target base station can perform uplink scheduling for UE before cell handover is completed, so as to reduce an uplink transmission latency caused by the cell handover.

An autonomous vehicle having wireless access communications access point equipment is arranged to set up a base station in a coverage hole by scanning to detect transmissions from another wireless communications access point, and determines a direction in which quality of coverage from the other wireless communications access point decreases, and directs the autonomous vehicle to move in the direction of decreasing coverage until it reaches a limit of coverage, at which point it hands over to another base station or, if no further base station is available, sets up as a wireless communications point connecting through the last base station to a backhaul connection.

The present invention relates to a method and a device for supporting a public safety network access in a wireless communication system. The method for supporting a public safety network access in a wireless communication system of the present invention comprises the steps of: transmitting a message comprising public safety net related information to a base station; determining whether a handover command is received from the base station in response to the message; and performing a handover at a frequency band which supports public safety network services.

A random access method includes: determining whether a currently selected beam for transmitting a preamble is identical to one of at least one recorded beam, clearing all previously recorded beams, recording the currently selected beam, and transmitting the preamble at a boosted pilot transmission power when it is determined that a value of a pilot power boost counter does not reach a maximum value.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that the UE is configured to use a two-step random access channel (RACH) procedure. The two-step RACH procedure may include an uplink request message and a downlink response. The UE may transmit the uplink request message as part of the two-step RACH procedure, and the uplink request message may include a preamble portion that is one of a set of predefined sequences and a payload portion that includes a physical uplink shared channel waveform. The UE may receive the downlink response as part of the two-step RACH procedure and in response to the uplink request message.

The application provides a handover processing method and a base station. The method includes: receiving a handover request message sent by a source base station or a core network node; sending a first message, according to the handover request message, to a second target base station to notify the second target base station that a handover of part or all of a service of a user equipment to the second target base station is to be performed; and sending a handover request acknowledge message to the source base station or the core network node to notify the source base station or the core network node to hand over the user equipment to at least one target cell of the first target base station and/or at least one target cell of the second target base station. The present application realizes a multi-cell handover.

There is disclosed a method, and a corresponding apparatus, for maintaining the settings of a user equipment, comprising: monitoring at least one stored setting in the terminal; responsive to a change in said at least one stored setting notifying a controller; and responsive to said notification selectively resetting said at least one stored setting.

A method performed by an apparatus of wireless communications is provided. The method includes receiving a plurality of Random Access (RA) configurations associated with a set of Bandwidth Parts (BWPs), selecting a first BWP from the set of BWPs to perform an RA procedure, and selecting a first Synchronization Signal Block (SSB) associated with the first BWP. The first SSB may be configured with a first RA resource. The method further includes transmitting a first RA preamble using the first RA resource and setting the first BWP as a first-activated BWP when the RA procedure is successfully performed.

A packet routing method is provided according to an embodiment. The method includes: updating a first routing configuration configured to a source node and a second routing configuration configured to a target node in response to a handover of a user equipment (UE) from the source node to the target node; receiving a first packet with a first header reflecting a result of the handover; and transmitting the first packet with the first header according to at least one of the updated first routing configuration and the updated second routing configuration.
