Techniques are provided for informing a network of a timing source outage in a node and reestablishing a synchronized time in the node. An example method for providing a timing source outage notification includes detecting an outage of a timing source, determining one or more impacted nodes, generating one or more notification messages based at least in part on a communication context for each of the one or more impacted nodes, and transmitting the one or more notification messages.

Techniques are provided for handling positioning sessions in response to a timing source outage. An example method for configuring a positioning method based on a timing source outage includes receiving an indication of the timing source outage from a station, determining the positioning method based at least in part on the indication of the timing source outage, and sending an indication of the positioning method to one or more network entities.

An object of the present disclosure is to provide a management apparatus, a communication apparatus, a system, a method, and a program capable of providing a service that meets a targeted KPI. A management apparatus according to the present disclosure includes: KPI management means for acquiring a target Key Performance Indicator (KPI) of a service that is provided to a communication terminal by a business operator; operation state acquisition means for acquiring element data regarding a component necessary for the service, the element data indicating a feature of a control system of the service; KPI prediction means for calculating a predicted KPI which is a predicted value of the KPI of the service based on the element data; and communication performance calculation means for, when the KPI is defined so that a value becomes lower as performance becomes better, detecting the component in which the predicted KPI is equal to or greater than the target KPI.

A communication device constitutes a management node that manages at least one of a first base station and a second base station provided on fronthaul. The communication device includes an acquisition unit that acquires a delay profile of the second base station, a control unit that determines a window parameter used to specify at least one of a Reception window and a Transmission window used in the first base station based on the delay profile of the second base station and a delay parameter defined by the fronthaul, and a notification unit that notifies the first base station of the window parameter.

This application provides a communication method and a communication apparatus. One example method includes: A sending device sends a first physical layer protocol data unit PPDU over a first link, where the first PPDU carries a trigger frame. The sending device sends a second PPDU over a second link, where an end time of sending the second PPDU is not earlier than a first time and not later than a second time, the first time is related to an end time of sending the first PPDU and a state turnaround time in a short interframe space SIFS time, and the second time is related to the end time of sending the first PPDU and the SIFS time.

Provided are a measurement method and apparatus, and devices. The method comprises: a terminal device acquiring a plurality of measurement parameters of a network device; and the terminal device determining a first measurement parameter from the plurality of measurement parameters, and performing measurement on a TN cell according to the first measurement parameter. The communication performance between the terminal device and the network device is improved.

A wireless communication method and device are provided. The method includes: a network device detecting, on the basis of M candidate time positions of a synchronous signal block, whether a carrier on an unlicensed frequency band is idle, the M candidate time positions being at least part of L candidate time positions of the synchronous signal block, the L candidate time positions being all the candidate time positions within a single transmission period of the synchronous signal block; according to a detection result, the network device sending the synchronous signal block at at least one of the M candidate time positions.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a measurement of a wireless signal from a first base station of a network, the measurement comprising one or more of: a Doppler shift of the wireless signal or an angular variation of the wireless signal; determine that a high speed train or tunneling (HSTT) event has occurred based at least in part on the measurement; provide, to the first base station, an indication that the HSTT event has occurred; and receive, from the first base station, configuration information to: configure the UE for a handover to a second base station of the network, configure the UE for beam switching, or cause the UE to change a connection state. Numerous other aspects are provided.

The present disclosure provides a reliability assurance method and a related apparatus. A receiving end device (watchdog) detects a continuous packet loss state, and sends the continuous packet loss state to an access network device, so that the access network device adjusts differentiated scheduling and a reliability assurance policy based on the continuous packet loss state.

This disclosure provides systems, methods, and devices for wireless communication that support enhanced positioning operations using a repeater. In a first aspect, a method of wireless communication includes receiving, by the UE, an instruction from a base station (BS) to perform a first signal measurement at a first time and a second signal measurement at a second time; determining, by the UE and based on the instruction, a first signal characteristic of a first signal during the first time corresponding to a time when a first repeater is repeating the first signal from a base station; determining, by the UE and based on the instruction, a second signal characteristic of a second signal during the second time corresponding to a time when the first repeater is not repeating the second signal; and a location of the UE is determined based on the first signal characteristic and the second signal characteristic.
