Abstract

The present application discloses a group feedback method for coded blocks in downlink control information, which is used in a mobile communication system. The downlink control information includes second information, and the second information includes ACK / NACK feedback information for uplink data channel data; The second information further includes third information and or fourth information, the third information includes data block feedback information, and the fourth information includes coding block group feedback information. This application also includes network devices, terminal devices and systems that reference it. The present application solves the problem that a network device feeds back multiple HARQ processes of an uplink data channel.

Description

technical field [0001] The present application relates to the field of mobile communication technologies, and in particular, to a method and device for grouping feedback of coded blocks in downlink control information. Background technique [0002] With the completion of the first version of the 5G New Radio (NR) standard, 5G will gradually expand to different fields. One of the important directions is the use of unlicensed frequency bands. Compared with the licensed frequency band, the unlicensed frequency band needs to consider the coexistence of different systems, such as the Wifi system and the LTE-based LAA system. In order to enable various systems to coexist harmoniously, regulatory agencies in various countries adopt the mandatory listen-before-transmit (LBT) technique for the use of unlicensed frequency bands, that is, data transmission can only be performed when it is detected that the current channel is not occupied. The problem with this mechanism is that some ...
