Power determination method and device

Abstract

The invention provides a power determination method and device. The power determination method comprises: a terminal device determines a first NR power according to a first AMPR, and the first AMPR iscalculated according to first resource allocation information and NR scheduling information, and the terminal device accesses to a first access device through an LTE access technology and accesses toa second access device through an NR access technology; the terminal device determines LTE power according to the second AMPR, and the second AMPR is obtained through calculation according to the LTEscheduling information and the second resource allocation information; and when the sum of the first NR power and the LTE power is greater than the maximum transmitting power of the terminal equipment, on all or part of the overlapped time domain resources, the terminal device sends LTE information to the first access device by using the LTE power and sends information to the second access deviceby using second NR power or does not send the NR information, and the second NR power is smaller than the first NR power. According to the scheme, the condition that the transmitting power exceeds the maximum dual-connection transmitting power when the terminal device transmits the signals to the two pieces of access device at the same time can be avoided.

Description

technical field [0001] The present application relates to the communication field, and in particular to a power determination method and device. Background technique [0002] A dual connectivity (DC) communication system is a communication system in which two network devices communicate with terminal devices at the same time. Compared with a communication system using carrier aggregation, an advantage of a DC communication system is that it allows different network devices to communicate with each other. The system time of the cell is not synchronized. [0003] The above two network devices are, for example, a primary base station and a secondary base station, where the primary base station may be a base station (eNB) in a long term evolution (longterm evolution, LTE) system, and the secondary base station may be a base station in a new radio (new radio, NR) system Base station (gNB), since the DC communication system allows the system time of the corresponding cells of eNB...

Problems solved by technology

[0003] The above two network devices are, for example, a primary base station and a secondary base station, where the primary base station may be a base station (eNB) in a long term evolution (longterm evolution, LTE) system, and the secondary base station may be a base station in a new radio (new radio, NR) system Base station (gNB), since the DC communication system allows the system time of the corresponding cells of eNB and gNB to be out of sync, and NR has different numerology, the terminal equipment that forms the DC communication system with eNB and gNB may have transmission time during transmission The problem of overlapping, if the above-mentioned terminal equipment transmits information to eNB and gNB at the same time in a frequency band (band), the maximum transmission power of the terminal equipment may be exceeded, resulting in communication failure
