Description
The present invention relates to the field of communications, and in particular, to a method for reporting a spectrum, a terminal device, and a network device.
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 the early stage, complete NR coverage is difficult to obtain, so typical network coverage is domain Long Term Evolution (LTE) coverage and NR islanding coverage mode, and since a large amount of LTE is deployed below 6 gigahertz (GHz), the spectrum below 6GHz available for 5G is very small.
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.
