Problems solved by technology

[0004] On the other hand, however, larger list sizes imply high complexity, which consumes more storage space and causes greater power loss
In particular, for terminal devices performing mMTC type communication, since a large number of blind detections need to be performed when receiving control channels, if a large list size is used, the power consumption of terminal devices will increase sharply, resulting in the inability to meet Low Power Requirements for mMTC Type Communications

Abstract

The embodiment of the invention relates to a communication method and a communication device. A communication method implemented at a first device is provided, and the communication method comprises the following steps: determining amount of information of a unit in control information; based on the amount of information of the unit and reliability of a subchannel used for bearing the control information, mapping the unit to the subchannel; and sending the control information to a second device through the subchannel. The invention also provides a communication method implemented at the seconddevice and the corresponding first device and second device.

Description

technical field [0001] Embodiments of the present disclosure generally relate to communication technologies, and more specifically, relate to a communication method implemented on a communication device and a corresponding communication device. Background technique [0002] Currently, polar coding has been proposed to be applied to the enhanced mobile broadband (eMBB) control channel of 5G networks, massive machine type communication (mMTC), etc. Compared with other coding schemes, polar coding schemes can bring advantages such as reduced complexity and increased capacity to communication systems. [0003] The decoding scheme corresponding to the polar coding scheme is usually list decoding, such as cyclic redundancy check (CRC) assisted list decoding. Typically, to achieve high performance, it is desirable to use a larger list size (eg, 32) for decoding. The complexity of polar coding is proportional to the list size, for example, the complexity of polar coding can be exp...
