METHOD AND APPARATUS FOR PUCCH RESOURCE MAPPING

摘要

A method for PUCCH resource mapping is provided, which includes in a traffic adaptive TDD system, classifying downlink sub-frames within a binding window into sub-frames of a first category and sub-frames of a second category, when feeding back HARQ-ACK (Hybrid Automatic Repeat request- Acknowledgement) for a downlink sub-frame, performing PUCCH (Physical Uplink Control Channel) resource mapping for a sub-frame of the first category in accordance with LTE/LTE-A, and performing PUCCH resource mapping for a sub-frame of the second category according to a specified order of sub-frames.

1. A method for PUCCH (Physical Uplink Control Channel) resource mapping, applied in a wireless communication system where PUCCH in sub-frame n carries HARQ-ACK (Hybrid Automatic Repeat reQuest-ACKnowledgement) information, comprising:
classifying PUCCH resources in sub-frame n into two categories; loading HARQ-ACK information of a sub-frame from a first category into a field belonging to resources of the first category; and mapping HARQ-ACK information corresponding to all of downlink data of sub-frames from a second category onto a field belonging to resources of the second category in a descending order of scheduling probability, with downlink data of high scheduling probability mapped onto PUCCH resources located far from PUSCH resources.
