Embodiment 1

[0108] In this embodiment, a method for feeding back confirmation information running on the above-mentioned network architecture is provided, figure 1 is a flowchart of a method for feedbacking confirmation information according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0109] Step S102, the receiving end device determines the mode of feedback confirmation information according to the decoding situation of the received transport block or code block group, wherein the confirmation information includes first confirmation information and second confirmation information;

[0110] Step S104, when it is determined that the transport block or the code block group is correctly decoded or neither is correctly decoded, the receiving end device generates first confirmation information based on the transport block, and transmits the first confirmation information in the first resource; Or, in a case where it is dete...

specific Embodiment 2

[0171] For a transmission, when the receiving end device correctly decodes all received CBGs or the receiving end device correctly decodes the received transport block TB, the receiving end device forms corresponding ACK / NACK information based on TB (each TB forms a 1-bit ACK / NACK information) and transmit it by punching or rate-matching the receiving device's own PUSCH. Otherwise, the receiver device forms the corresponding ACK / NACK information based on the CBG (each CBG forms a 1-bit ACK / NACK information) and transmits it in resource 2 using format 2. Resource 2 is configured by the base station for the UE.

[0172] Wherein, format 2 is used to transmit UCI information larger than 2 bits. Uplink control information (abbreviated as UCI) includes ACK / NACK information and other uplink feedback information (for other uplink feedback information, refer to the definition in the NR system).

[0173] For a UE1, there is a high probability of transmitting ACK / NACK based on TB throu...

specific Embodiment 1

[0184] For a receiver device, it is configured to form and send acknowledgment information ACK / NACK information allocation resource 1 based on the transmission block TB; it is configured to form and send ACK / NACK information allocation resource 2 based on the code block group CBG; for a transmission, when After the receiving end device correctly decodes all the received CBGs or the receiving end device correctly decodes the received transport block TB, the receiving end device forms the corresponding ACK / NACK information based on the TB (each TB forms a 1-bit ACK / NACK information) and uses the format 1 transmits it in resource 1. Otherwise, the receiver device forms the corresponding ACK / NACK information based on the CBG (each CBG forms a 1-bit ACK / NACK information) and transmits it in resource 2 using format 2.

[0185] Among them, format 1 is used for the transmission of 1-2 bits of uplink control information UCI information, and generally, it adopts higher reliability. For...

Abstract

The invention provides a feedback method and a feedback device of a confirmation message, and a receiving method and a receiving device of the confirmation message. The feedback method of the confirmation message comprises the steps as follows: receiving terminal equipment determines a mode for feeding back the confirmation message according to the decoding condition of received transmission blocks or received code block groups; under the condition of confirming that the transmission blocks or code block groups are correctly decoded or not correctly decoded, the receiving terminal equipment generates a first confirmation message based on the transmission blocks and transmits the first confirmation message in a first resource; or under the condition of confirming that not all transmission blocks or code block groups are correctly decoded, the receiving terminal equipment generates a second confirmation message based on the code block groups, and transmits the second confirmation messagein a second resource. By using the technical scheme provided by the invention, the problem that in related technologies how to more accurately and efficiently feed back the confirmation message is solved, and the receiving terminal equipment generates different confirmation messages according to the different decoding conditions, and accurately and efficiently feeds back the decoding condition ofthe receiving terminal equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to a confirmation information feedback method and device, and a confirmation information receiving method and device. Background technique [0002] Among the related technologies, the new generation mobile communication system NR (New Radio) under research is one of the current 3GPP work priorities. [0003] Among the NR systems that can be determined at present, there will be three typical service types in the future. Common services include: enhanced mobile bandwidth eMBB (enhanced Mobile BroadBand), ultra-reliable and ultra-low latency communication URLLC (Ultra-Reliable and Low Latency Communications), and large-scale IoT mMTC (massive MachineType Communications). These services have different requirements on delay, coverage and reliability. For example, for eMBB, high peak transmission rate is mainly emphasized, the requirement for delay is not high (there is no requirement ...
