Provided by the present disclosure are data transmission method and device. In an embodiment of the present disclosure, data transmission conditions of each serving cell among at least two serving cells is detected by means of a terminal so that the terminal may, according to the data transmission conditions of each serving cell, execute random access on a serving cell experiencing wave beam failure so as to update a service beam of the serving cell. Thus, when the terminal experiences wave beam failure in a serving cell in a carrier aggregation (CA) scenario, reliable data transmission may be achieved, and the reliability of data transmission may be effectively ensured.

This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

A processor-implemented method includes integrating telecommunication network provider performance analytics with vendor testing automation such that specific data from vendor user equipment (UE) testing can be filtered out and the performance data results represent true service performance for the desired UEs. A network device associated with the network provider may establish an application programming interface (API) with a vendor device associated with the vendor to receive vendor testing information used to identify UEs undergoing vendor testing. The network device may identify the vendor UEs undergoing vendor testing when performing measurements on a group of UEs, such as key performance indicator (KPI) measurements.

A monitoring device includes: an acquisition unit for acquiring a clock signal output from a communication circuit that outputs the clock signal; and a monitoring unit for analyzing the waveform of the clock signal acquired by the acquisition unit, based on a predetermined reference clock signal having a period equal to or shorter than a period of the clock signal to thereby determine whether or not there is a sign of malfunction in the communication circuit.

Disclosed is a pre-5G or 5G communication system for supporting higher data rates beyond 4G communication system such as LTE. An electronic device including a plurality of antenna modules in a wireless communication system is provided. The electronic device includes a transceiver and a processor configured to identify a first RSRP value and a second RSRP value by using a first antenna module of the plurality of antenna modules; determine to monitor a second antenna module of the plurality of antenna modules based on the first RSRP value or the second RSRP value; and, in response to determining to monitor the second antenna module, monitor the second antenna module. The first RSRP value is measured from a first reference signal of a serving cell, and the second RSRP value is measured from a second reference signal of a neighboring cell.
