| 发明名称 | Method and apparatus for allocating control channel in wireless communication system | ||
| 摘要 | Provided are a method and an apparatus for allocating a control channel in a wireless communication system. A base station allocates an enhanced physical downlink control channel (e-PDCCH) to a localized region within a physical downlink shared channel (PDSCH) region, allocates the e-PDCCH to a distributed region within the PDSCH region, and transmits a scheduling assignment via the allocated e-PDCCH. | ||

| 主权项 | 1. A method for allocating a control channel in a wireless communication system, the method comprising: allocating an enhanced physical downlink control channel (e-PDCCH); and transmitting a scheduling assignment through the allocated e-PDCCH, wherein the allocating the e-PDCCH comprises: when an enhanced control channel element (CCE) aggregation level of a corresponding e-PDCCH format is below a predetermined value, allocating the e-PDCCH to a localized region which is contiguously configured in a frequency domain, or a distributed region which is dispersedly configured in the frequency domain; andwhen the e-CCE aggregation level is not below the predetermined value, allocating the e-PDCCH to only to the distributed region. | ||
