The present disclosure relates to a communication technique for converging a 5G communication system, which is provided to support a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related service, or the like) based on the 5G communication technology and the IoT related technology. The disclosure relates to a method for recovering a beam into a correct beam according to a position of a terminal using a non-contention-based and contention-based beam failure recovery method in order to recover a beam failure in which communication is disconnected due to movement of a terminal or the like in a wireless communication system performing beam-based communication services.

A method and base station for distributing wireless device traffic load in a wireless communication system having a plurality of base stations are provided. A method includes determining a wireless device traffic load on a serving base station of the plurality of base stations. The method also includes determining a priority for each of a plurality of target base stations of the plurality of base stations, the priority being based at least in part on a number of wireless devices being served by the serving base station that receive a signal from a corresponding target base station that exceeds a threshold. The method further includes determining whether to change the load of the serving base station and sending a load change request to a target base station having a highest priority based on a comparison of the load on the serving base station to a load change threshold.

The present application at least describes a non-transitory computer readable medium including program instructions capable of being executed by a processor. The program instructions upon execution by the processor may cause the processor to detect a first group of radio resources on a first apparatus. Another program instruction may include detecting a second group of radio resources on a second apparatus. Even another program instruction may include determining capacity information of each radio resource in the first and second groups. Yet even another program instruction may include selecting a dedicated radio resource from the determined capacity information of the radio resources in the first and second groups. Even a further program instruction may include controlling the dedicated radio resource to communicate with a third apparatus.

When a downlink bandwidth part (BWP) is switched from a first BWP to a second BWP without a change of a cell defining synchronization signal block (SSB), if a reference signal type for Radio Link Monitoring (RLM) is set to an SSB type, a radio terminal (12) continues to use for RLM measurements a first SSB associated with the first BWP after switching of the downlink BWP to the second BWP. This for example enables the radio terminal to monitor a suitable Reference Signal (RS) for RLM measurements after switching of the DL active BWP.

A bearer modification method and an access network device. The method includes determining, by an access network device, that a terminal device completes a complete registration procedure, or determining that the terminal device does not complete the complete registration procedure, and waiting for the terminal device to complete the complete registration procedure, and modifying, by the access network device, a radio access bearer of the terminal device.

The present disclosure provides a frequency band switching method, an apparatus, a terminal device, a communication node and a computer-readable storage medium. The frequency band switching method comprises: determining a need for switching a frequency band of an uplink operation according to transmission power information of a terminal device when the uplink operation of the terminal device is performed in a first frequency band; performing, by the terminal device, a beam scanning for a second frequency band to switched to; and switching, by the terminal device, to the second frequency band according to a beam scanning result.

The present invention relates to a wireless communication system, specifically, to a method and an apparatus therefor, the method comprising: receiving BWP switching information from a first BWP; switching from the first BWP to a second BWP on the basis of the BWP switching information; switching to a third BWP different from the second BWP on the basis of transmission failure of a first uplink from the second BWP; and transmitting a second uplink from the third BWP, wherein the third BWP is one from among the first BWP, an initially activated BWP used for initial access, and a previously configured BWP.
