BASE STATION, USER EQUIPMENT AND METHOD FOR TRANSMITTING PHYSICAL UPLINK CONTROL INFORMATION

摘要

The present invention discloses a method for transmitting physical uplink control information, a base station (BS) and a user equipment (UE), combining channel information feedback based on non-periodic PUSCH and channel information feedback based on periodic PUCCH. The BS activates reception of one or more downlink Secondary Component Carriers (SCCs) by the UE, and notifies the UE of resources for non-periodic transmission of uplink control information. The UE jointly codes Channel State Indicators (CSIs) for downlink Component Carriers (CCs) including a downlink SCC and/or a downlink Primary Component Carrier (PCC) and transmits them to the BS by using the resources. The BS performs a downlink scheduling based on the CSIs. The UE feeds CSIs for the downlink CCs back to the BS periodically, such that the BS can track variation in the CSIs for the downlink CCs. With the present invention, it is possible to address challenges in designs for transmitting physical uplink control information in the LTE R-10 system.
