Abstract: A method for aggregation transmission of multi-user downlink data and an apparatus. A network device performs, based on a specific aggregation rule, bit aggregation on downlink data of a terminal device in a terminal device group, performs channel encoding and modulation on data obtained through the bit aggregation, and sends the data to a plurality of terminal devices participating in aggregation transmission. Each terminal device that receives the downlink data obtains, based on the aggregation rule, respective downlink data from the received data obtained through the bit aggregation. According to this method, the network device performs channel encoding on an aggregated bit sequence, thereby increasing a sequence length before encoding, and improving a coding gain.

Abstract: This application provides a feedback information transmission method and an apparatus. The method includes a terminal device that receives indication information from a network device. The indication information indicates to generate a semi-static codebook. The terminal device detects a first physical downlink shared channel (PDSCH) at M candidate receiving positions in a first time unit. The first PDSCH is a semi-persistent scheduling (SPS) PDSCH or a grant-free PDSCH, and M is a positive integer. The terminal device determines, based on a detection result of the first PDSCH, whether to send first feedback information to the network device. The first feedback information includes acknowledgement (ACK) information or negative acknowledgement (NACK) information indicating whether the first PDSCH detected at the M candidate receiving positions is correctly decoded.

Abstract: This application provides a data transmission method and an apparatus, in which two radio access network devices share a resource. A first radio access network device determines a resource occupation status corresponding to a different status of a second access network device on a shared resource. The first radio access network device indicates the resource occupation status to a terminal device served by the first radio access network device. The terminal device determines an available resource in a shared carrier based on the resource occupation status, and communicates with the first access network device using the available resource. The first radio access network device can perform communication on the shared resource regardless of a status of the second radio access network device on the shared resource, so that the two radio access network devices flexibly and efficiently coexist in the shared carrier. This improves utilization of the shared resource.
