Description

Method for reporting radio frequency capability, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method, a terminal device, and a network device for reporting radio frequency capability.

Background

With the pursuit of people for speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of services in future life.

For this reason, The international standards organization for The third Generation Partnership Project (3 GPP) began to develop a fifth Generation mobile communication technology (5-Generation, 5G). The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), Low-Latency and high-reliability Communication (URLLC), and massive machine type Communication (mMTC).

When New Radio (NR) is deployed in an early stage, complete NR coverage is difficult to obtain, so typical network coverage is Long Term Evolution (LTE) coverage in a wide area and an islanding coverage mode of NR. Also, since a large amount of LTE is deployed below 6 gigahertz (GHz), the below 6GHz spectrum available for 5G is rare. Therefore, NR must be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading.

In the prior art, in order to protect the LTE investment of a mobile operator in an early stage, a tight interworking (light interworking) working mode between LTE and NR is proposed. Specifically, the data transmission is supported by bandwidth (band) combination to support LTE-NR Dual Connectivity (DC), thereby improving system throughput.

However, since the radio frequency design of the mobile phone is designed according to a frequency band (band), after the mobile phone accesses the network, the mobile phone reports its radio frequency capability based on the band, which results in high complexity and cost of the terminal device.
