Problems solved by technology
In order to ensure that all types of information can be correctly decoded, the user equipment must use higher transmission power and calculations to process the information with different error rate requirements, thus causing transmission power and calculations to be wasted on error rate requirements. Lower information (e.g. channel state information)

Embodiment Construction
[0016] Embodiments of the present invention will be described below in conjunction with related drawings. In the drawings, the same reference numerals represent the same or similar elements or method flows.
[0017] In this specification, the framework of the third generation partnership project long term evolution technology (Third Generation Partnership Project Long Term Evolution, 3GPP LTE) is used as an embodiment for description. However, the present invention is not limited to the LTE architecture of the 3rd Generation Partnership Project, and the embodiments disclosed in this specification can also be applied to other communication systems.
[0018] When the user equipment receives a signal transmitted from the network, the user equipment needs to transmit corresponding confirmation information to the network to show whether the user equipment has received the signal. For example, an acknowledgment (ACK) indicates that the packet transmitted by the network has been suc...

The present invention proposes a communication device for uplink transmission of coded information and a related communication method. The communication device includes: a demultiplexing circuit, a code vector selection circuit, a sorting circuit, and a Reed-Muller coding circuit. The demultiplexing circuit generates a first information bit group and a second information bit group according to the first type of information and the second type of information. The code vector selection circuit selects a code vector from a preset vector set according to the first information bit group and the second information bit group. The sorting circuit sorts the code vectors according to the first information bit group and the second information bit group. The Reed-Muller encoding circuit encodes the first information bit group, the second information bit group and the sorted code vectors to provide different levels of protection. The aforementioned architecture can provide different levels of protection correspondingly according to different types of information, and can effectively reduce transmission power and calculation load.
Description
technical field [0001] The present invention relates to uplink transmission of coded information in mobile communication, in particular to a communication device for uplink transmission of coded information and a related communication method. Background technique [0002] The convenience brought by mobile communication makes it an indispensable role in modern life. Many people are used to performing more and more work on mobile communication devices, such as surfing the Internet, watching videos, and making voice calls. Therefore, in response to users' demands for higher-speed mobile communications, many technologies for increasing the transmission rate of mobile communications have been proposed and adopted. For example, carrier aggregation technology (carrier aggregation) can be used to aggregate the bandwidth of multiple component carriers (component carriers) to increase the data transmission rate. In addition, by effectively utilizing the channel state information (CS...
