Problems solved by technology

However, due to the transmission failure caused by the channel, signal, and unpredictable interference as mentioned above, the ACK or WtACK sent by the receiving end cannot be received by the sending end, which will affect subsequent transmissions.
There is currently no solution to this problem

Abstract

The invention provides an indication method, network equipment and user equipment. The network equipment displays or implicitly indicates the receiving response of one or more downlink transmission unit sets to be received by the network equipment through indication information (including but not limited to a bit map, information indicating the number Wt and information indicating the index) carried on one or more downlink transmission units; in this way, it is indicated that the UE needs to send the receiving response of one or more downlink transmission unit sets to the network device, so that the UE can correctly send the receiving response of the downlink transmission unit set sent by the network device on the correct uplink transmission unit. Therefore, errors are reduced, unnecessaryretransmission is avoided, the service quality is ensured, and the communication efficiency is improved. Especially on an unlicensed uplink transmission unit (channel) which is firstly monitored andthen sent, the error rate of the whole communication system can be further reduced, and the communication quality and efficiency are improved.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to an indication method, network equipment and user equipment. Background technique [0002] In a cellular communication system, due to the time-varying characteristics of wireless channels and the impact of multipath fading on signal transmission, as well as some unpredictable interference, signal transmission will fail. Therefore, an indication method such as a hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat reQuest) mechanism or an automatic repeat request (ARQ, Automatic Repeat-reQuest) can generally be used for error control. When the data arrives at the receiving end, the receiving end performs error detection on it, and returns a positive acknowledgment (Acknowledgment, ACK) if it is received correctly, and returns a negative acknowledgment (Negative Acknowledgment, NACK) if it is wrong. However, due to the aforementioned channel, signal, and unpre...
