The third generation partnership project conference document R1-150429 (proposed by sony corporation) discloses a time-frequency structure in which a legacy mobile terminal (legacy UE) and a narrowband mobile terminal (narrowband UE, the specific definitions of which are well known to those skilled in the art and are not described in detail by the applicant, and the specific definitions of which can be known by searching the prior art) coexist. The time-frequency structure specifies that control information for legacy UEs is transmitted in a legacy control region (i.e., the frequency domain is the system bandwidth, and the time domain is the first three (or two) symbols of a subframe), and control information for narrowband mobile terminals is transmitted on ePDCCH, and the prior art specifies how to allocate PDSCH frequency resources (e.g., the light green segment in fig. 1 of this document is a PDSCH region dedicated to narrowband mobile terminals, and the region dedicated to narrowband mobile terminal control and data becomes a narrowband region). The inventor finds that the prior art has a problem of wasting power consumption, and when the time-frequency resource partitioning strategy is used, the conventional mobile terminal does not receive control information on the narrowband region and does not receive data messages on the narrowband region, so DMRS and CRS transmitted in the narrowband region are useless for the conventional mobile terminal. For example, CRS may be used to estimate CQI, but since legacy UEs do not communicate in the narrowband region, it makes no sense for legacy UEs to estimate CQI for this portion of the band, and the CQI for this portion of the band will interfere with the CQI estimation that is actually used for legacy UEs. In order to not monitor the reference signal on the narrowband, the legacy UE needs to know the position of the narrowband, and needs to know the position of the narrowband, so that the legacy UE is required to blindly detect the ePDCCH channel on the narrowband, which causes power consumption of the legacy UE. Furthermore, the latter 4G (B4G) and 5G era began to propose the concept of URLLC transmission, and URLLC class mobile terminals may need to occupy resources already allocated to other mobile terminals to achieve short TTI scheduling, flexible scheduling, and timely scheduling, thereby reducing latency (this aspect of technology often focuses on the design of "preemption indicators"). For example, CN201580025563.9 discloses a method for transmitting a preemption indicator on a "thin" control channel (the thin control channel is an ePDCCH channel, but the term is not specified enough since the document is older), but this method does not solve the problem of a conventional mobile terminal and a narrowband mobile terminal, for example, the conventional mobile terminal does not listen to a narrowband portion, and the narrowband mobile terminal must not listen to another additional thin control channel, which causes difficulties and contradictions in using this patent technology in conjunction with the aforementioned R1-150429.
