Title:
WIRELESS COMMUNICATION METHOD, TERMINAL DEVICE, AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/092431
Kind Code:
A1
Abstract:
Provided are a wireless communication method, a terminal device, and a network device. The method comprises: a terminal device receives first DCI, the first DCI being used for scheduling N PDSCHs, and HARQ-ACK information corresponding to M PDSCHs among the N PDSCHs being fed back on the same PUCCH. The M PDSCHs comprise a first PDSCH, the time domain position of the first PDSCH is associated with a first time unit set, and the first time unit set is determined based on at least one of the following information: a feedback time sequence set, a first subcarrier spacing and a second subcarrier spacing of the terminal device. The first subcarrier spacing is a subcarrier spacing of the first PDSCH or a subcarrier spacing of a first carrier where the first PDSCH is located, and the second subcarrier spacing is a subcarrier spacing of a PUCCH or a subcarrier spacing of a second carrier where the PUCCH is located. The described solution considers one or more factors such as the feedback time sequence set, the first subcarrier spacing associated with the PDSCH and the second subcarrier spacing associated with the PUCCH, and helps to implement the scheduling of multiple PDSCHs by one DCI in a multicarrier scenario.
