AI Technical Summary

Problems solved by technology

However, considering factors such as the limitation of the shape of the terminal battery (such as a button battery) in the M2M application field of NB-IoT, the power of the terminal is limited, the transmission power of this type of terminal is low, and the uplink coverage capability is poor, so it can be called low power class UE
If the parameters used by regular UEs are still configured for low-power class UEs, it may cause low-power class UEs to be unable to access the network or perform normal communication

Embodiment Construction

[0316] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0317] In the NB-IoT system, the maximum transmission power of a conventional NB-IoT terminal is 20dBm or 23dBm, and the maximum transmission power of a UE is represented by the UE Power Class (UE Power Class). For example, if the maximum transmission power of a UE is 20dBm, the UE Power Class 3; UE Power Class 5 corresponds to UE maximum transmit power of 23dBm. However, in the M2M application field of NB-IoT, the maximum transmit power of the terminal may be as low as 14dbm, and corresponding parameters need to be configured for low-power UEs to enable them to access the network.

[0318]For low-power UEs, the maximum uplink coverage is smaller than the maximum coverage of high-power UEs. For multi-band networks, the lower the frequency, the greater the wireless coverage. ...
