Embodiment Construction

[0081] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0082] In order to reduce the number of repetitions of the downlink control information of the MTC UE under coverage enhancement, thereby improving the utilization rate of radio resources and reducing the power consumption of the MTC UE, one way is to reduce the DCI (Downlink Control Information, downlink control information) of the MTC UE. The number of bits, especially the number of bits occupied by the resource allocation field in the DCI. The embodiment of the present invention provides a method for determining the narrowband of the physical channel. Through the method in...

Abstract

The invention discloses an information transmission method, and the method is used for a user terminal. The method comprises the steps: determining a narrow band of a physical channel; and transmitting or receiving the information on the physical channel according to the narrow band of the physical channel. The method can reduce the resource distribution cost, and saves the power consumption of the user terminal.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for transmitting information. Background technique [0002] Machine Type Communication (MTC for short) user equipment (User Equipment, short for user equipment or user terminal), also known as Machine to Machine (M2M for short) user equipment, is currently the main application form of the Internet of Things . [0003] In recent years, due to the high spectrum efficiency of Long-Term Evolution (LTE for short) / Long-Term Evolution Advance (LTE-Advance or LTE-A for short) Suppliers choose LTE / LTE-A as the evolution direction of broadband wireless communication systems. MTC multi-type data services based on LTE / LTE-A will also be more attractive. [0004] The MTC device is generally a low-cost device, and has the characteristics of a relatively small supported radio frequency (Radio Frequency, RF) bandwidth and a single receiving antenna, ...
