Use of the physical uplink control channel in a 3RD generation partnership project communication system

摘要

In a 3 rd Generation Partnership Project communication system a base station (103) comprises a scheduler (105) allocating communication resource of at least one of a Physical Uplink Shared CHannel, PUSCH, and a Physical Downlink Shared CHannel, PDSCH to a User Equipment (UE) (101). The scheduling may either be a dynamic scheduling wherein a resource allocation for a single frame is provided to the UE or a persistent scheduling wherein a resource allocation for multiple frames is provided to the UE. A resource allocator (107) assigns resource of a Physical Uplink Control CHannel, PUCCH, to the UE dependent on whether dynamic scheduling or persistent scheduling is performed by the scheduler for the UE. The UE transmits uplink control data on a physical uplink channel which is selected as the PUCCH or the PUSCH in response to whether persistent scheduling is used for the UE. The invention allows reduced PUCCH loading.
