Abstract
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.
Claims25
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.
An apparatus for PUCCH (Physical Uplink Control Channel) resource mapping, applied in a wireless communication system where PUCCH in sub-frame n carries HARQ-ACK information, comprising:
- a controller which classifies PUCCH resources in sub-frame n into two categories, loads HARQ-ACK (Hybrid Automatic Repeat Request-Acknowledgement) information of a sub-frame from first category into a field belonging to resources of a first category, and maps 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.
