Abstract

本申请实施例提供一种传输方法及装置，该方法包括：根据用于指示下行控制信息的资源的第一标识，确定第二标识，其中，第二标识为HARQ码本所对应的高层配置的标识，HARQ码本为下行控制信息对应的PDSCH的HARQ反馈所使用的码本。通过根据指示下行控制信息的资源的第一标识，确定HARQ码本所对应的CORSET Pool Index的第二标识，从而可以根据第二标识生成HARQ码本，避免了PDSCH在反馈时无法确定应该按照哪个CORSET PoolIndex的CORESET来生成HARQ码本的问题。

Embodiments of the present application provide a transmission method and apparatus, the method includes: determining a second identifier according to a first identifier used to indicate a resource of downlink control information, where the second identifier is an identifier configured by a higher layer corresponding to a HARQ codebook Identifier, the HARQ codebook is a codebook used for HARQ feedback of the PDSCH corresponding to the downlink control information. By determining the second identifier of the CORSET Pool Index corresponding to the HARQ codebook according to the first identifier of the resource indicating the downlink control information, the HARQ codebook can be generated according to the second identifier, and it is avoided that the PDSCH cannot determine which should be followed during feedback. CORESET of CORSET PoolIndex to generate HARQ codebook problem.
