Embodiments of the present invention disclose a measurement method, including: acquiring, by user equipment, a status of using a target unlicensed frequency band by a target radio access technology RAT; and selecting, by the user equipment, a corresponding measurement mode according to the usage status to measure a radio condition of the target unlicensed frequency band. The embodiments of the present invention further disclose user equipment, a network device, and a system.

A terminal includes a receiver that receives information regarding a measurement to be performed in a first serving cell using a synchronization signal block (SSB) and a processor that performs the measurement according to the information and determines whether transmission or reception can be performed using a second serving cell, at a specified timing, based on at least one of an SSB-based measurement timing configuration (SMTC) window duration and an SSB to be measured in regard to the first serving cell. In other aspects, a radio communication method for a terminal, a base station and a system are also disclosed.

Methods and apparatuses in a wireless communication system. A method of operating a user equipment (UE) includes storing a previous layer 3 (L3) filtered measurement result; receiving L3 filtering configuration information including a first filter coefficient value (k) and a first filtering window value; identifying a generation time instance of the previous L3 filtered measurement result; identifying the first filter coefficient value (k) and the first filtering window value included in the L3 filtering configuration information; in response to receiving a latest measurement result from a lower layer, determining whether the generation time instance of the previous L3 filtered measurement result was obtained within a time window that is a function of a first time instance and a second time instance; and performing an L3 filtering operation to trigger a measurement report based on a result of the determination.

A wireless device (18) detects a failure associated with a first cell group among multiple cell groups (14A, 14B) that are respectively provided by multiple radio network nodes (12A, 12B) to which the wireless device (18) simultaneously connects in multi-connectivity operation. The wireless device (18) transmits a report (20) that reports the detected failure. The report (20) includes information about a conditional configuration (16) stored at the wireless device (18).

Provided are a measurement method and apparatus, and a terminal device. The method comprises: a terminal device receiving first instruction information sent by a network device, wherein the first instruction information is used to instruct an SCG to enter a first state, and the first state is different from an active state; and the terminal device executing measurement according to a first measurement behavior after the SCG enters the first state.

Embodiments of the present application provide a non terrestrial communication network NTN handover method, a device, and a storage medium; and the method includes: a terminal device measuring channel measurement parameters and location measurement parameters of a current serving cell and at least one first adjacent cell; the terminal device sending the measurement results of the current serving cell and at least one second adjacent cell to a network device; where the second adjacent cell is an adjacent cell which satisfies a measurement reporting condition; where the measurement results are configured to instruct the network device to determine a target cell to be handed over for the terminal device; and the terminal device performs handover according to a handover command received, where the handover command is configured to instruct the terminal device to perform handover from the current serving cell to the target cell.

The present disclosure discloses a method and device in UE and base station used for wireless communications. A UE transmits a first radio signal, the first radio signal indicating a first reference signal out of M reference signals; and monitors a first signaling in each of W time-frequency resource block(s). Herein, at least one reference signal of the M reference signals is transmitted by a first serving cell, and the first serving cell is not added by the UE; the UE assumes that a transmission antenna port of the first signaling is Quasi-Co-Located with a transmission antenna port of the first reference signal; W is a positive integer, and M is a positive integer greater than 1. Such method can be employed to avoid delay and service interruption brought about by cell handover.

The disclosure generally relates to various methods to increase network coverage for a Voice-over-Internet Protocol (VoIP) session between a first user equipment (UE) and a second UE. In an aspect, a first and second UEs negotiate a codec configuration to use in the VoIP session, transmits, to the second UE, a maximum end-to-end packet loss rate (PLR) that the first UE can tolerate for received media given the negotiated codec configuration, receives, from the second UE, a maximum end-to-end PLR that the second UE can tolerate for received media given the negotiated codec configuration, and determines a distribution of the maximum end-to-end PLRs among respective uplinks and downlinks at the first UE and the second UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a beam measurement report associated with a serving beam of the UE. The UE may determine that a timer, relative to transmission of the beam measurement report, has expired. The UE may perform a measurement of one or more neighbor beams based at least in part on determining that the timer has expired. Numerous other aspects are provided.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.
