Described herein are techniques and systems for selectively transitioning communication sessions from TDD to FDD based on service type and uplink quality. The selective transitioning of communication sessions from TDD to FDD can provide higher and more reliable uplink throughput to UEs, as needed. An example process includes determining, during setup of a communication session for a UE using TDD, a type of service associated with the communication session, and determining that the type of service is a predefined service of a set of predefined services. The example process may further include determining a value indicative of a quality associated with an uplink connection established by the UE, determining that the value fails to satisfy a threshold value, and transitioning, based at least in part on the value failing to satisfy the threshold value, the communication session to a target base station to finish the setup using FDD.

Disclosed are an apparatus and a method in a wireless communication system and a computer readable storage medium, the apparatus comprising a processing circuit, and the processing circuit being configured to: configure a measurement cell range of a user device to include adjacent cells of the current serving cell of the user device and cells other than the adjacent cells; and notify the user device of the measurement cell range, such that the user device implements measurement for the measurement cell range. According to at least one aspect of the embodiments of the present disclosure, expanding the measurement cell range for an unmanned aerial vehicle to include cells other than adjacent cells can prevent the occurrence of frequent handover.

A method for reducing temperature for user equipment (UE), includes: receiving a handover request from a source base station, wherein the handover request carries at least one of configuration information expected by the UE and indication information indicating that the UE overheats; and sending first configuration information to the UE based on the handover request, wherein the first configuration information is configured for the UE to update its own radio communication parameter configuration to reduce the temperature of the UE, and the first configuration information is the same as or different from the configuration information expected by the UE.

A Bluetooth communication system is provided, which comprises a Bluetooth host device and a Bluetooth device set. The connections between the Bluetooth host device and the Bluetooth device set complies with the specification of Bluetooth Low Energy Audio technology. The Bluetooth device set comprises at least a first member device and a second member device. The first member device and the second member device may be configured in a first mode wherein uplink audio signal transmission is allowed, and the connections are carried out by isochronous streaming channels respectively. The first member device transmits captured voice data to the Bluetooth host device, while the second member device does not transmit. When an event is triggered, the first member device can notify the second member device through a third-part device, so that the first member device and the second member device can carry out subsequent voice input handover procedures.

An apparatus and a method in a wireless communication system. In the wireless communication system, a master device provides a data forwarding service for one or plural slave devices, a master device side apparatus including: a monitoring unit, configured to monitor a predetermined trigger event relating to a change in state of the master device; a handover pre-measurement control unit, configured to respond to the predetermined trigger event by controlling the handover pre-measurement of the one or plural slave devices; and a handover measurement control unit, configured to control, based on the handover pre-measurement results, the handover measurement of the one or plural slave devices. The apparatus and method can accelerate start time of effective link handover in a dynamic network, reduce unnecessary link handover, and reduce delays and data loss caused by link failure.

Proposed is a method for a first device to perform wireless communication. The method may comprise the steps of: establishing a connection with a second device; and reselecting a cell on the basis that the first device is in a radio resource control (RRC) IDLE state or an RRC INACTIVE state. For example, a priority related to cell reselection can be set such that a cell related to a new radio (NR) has a high priority. For example, cell reselection can be performed first on the cell related to the NR on the basis of the priority related to cell reselection.
