This patent application is a 35 USC § 371 U.S. national stage of International Application No. PCT/CN2018/100429 filed on Aug. 14, 2018, which claims priority to Chinese Patent Application No. 201710813749.1 filed on Sep. 11, 2017, which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of communications technologies, and in particular, to a transmission control method, a related device and system.
The interference problem has always existed in communication technology, and the interference has seriously affected the communication performance of the User Equipment (UE). The common interferences include the interference between different terminals, interference between different systems, etc. However, with the development of communication technology and increasing people's requirements for the performance of UEs, another type of interference, i.e., an intra-UE interference has been paid more and more attention by the people. The intra-UE interference refers to that the interference generated by the signal transmitted by the UE itself affects the received signal of the UE. For example, the uplink signal transmitted by the UE interferes with the downlink signal of the UE. Due to the intra-UE interference, the transmission performance of UEs is poor.
In a first aspect, a transmission control method is provided in the embodiments of the present disclosure, applied to a UE, including:
