Adaptive two stage downlink control channel structure for code block group based fifth generation (5g) or other next generation systems

摘要

An adaptive two-stage downlink control channel structure is utilized for control channel transmission using code block group (CBG) retransmissions for 5G and other next generation radio systems. In one aspect, the first stage of the two-stage downlink control channel structure utilizes a defined format (eg, has a fixed length) and the length and / or coding scheme of the second stage. Provide information that is available to ask. In another aspect, the second stage of the two-stage downlink control channel structure utilizes a variable length / size indicating a CBG that is scheduled to be retransmitted (eg, by utilizing a variable length bitmap). .. As an example, the length / size varies based on the length / size of the transport block from which the CBG is generated. [Selection diagram] Fig. 1
