Abstract:
A communication method, a communication device for a dual-SIM card-dual-call, DSDC, terminal, and the DSDC terminal are provided. The DSDC terminal includes a first radio frequency subsystem for initiating Packet Switching, PS, service and a second radio frequency subsystem for initiating Circuit Switching, CS, service. The transmission power for the PS service of the first radio frequency subsystem is controlled to be under a predetermined value during a reception timeslot for the CS service of the second radio frequency subsystem, thereby overcoming the problem caused by the interference between two radio frequency subsystems of the DSDC terminal.
Abstract:
Handling a frequency error (FEQ) of a terminal which includes a plurality of modems using a same clock source includes: obtaining the FEQ, which is a difference between a carrier frequency of a received signal and a nominal frequency for each modem; obtaining a FEQ threshold of the received signal in a current service based on the FEQ; obtaining an adjusted value of the clock source corresponding to each modem based on the FEQ and the FEQ threshold; obtaining a synthesized adjusted value of the clock source based on the adjusted values of all the moderns; and adjusting the frequency of the clock source based on the synthesized adjusted value of the clock source. The FEQ of the mobile communication terminal can be quickly corrected by adjusting the clock source's frequency, and, by considering the FEQ of all the modems, the modems' performances may be balanced.
