CROSS-CARRIER INDICATION METHOD AND USER EQUIPMENT

摘要

The present invention discloses a method for performing cross-carrier indication and corresponding user equipment. The method comprises steps of detecting a PCFICH on a first carrier carrying a PDCCH and acquiring control information symbol number information on the first carrier; detecting the PDCCH on the first carrier and acquiring PDSCH resource block assignment information, carrier indicator and HARQ information according to the control information symbol number information on the first carrier; detecting control information symbol number information on a second carrier carrying a PDSCH indicated by the acquired carrier indicator; and acquiring or not acquiring the PDSCH according to the acquired control information symbol number information on the second carrier and/or the PDSCH resource block assignment information. This method can detect PCFICH errors on a carrier carrying the PDSCH, or improve detection performance for the PCFICH of the carrier, or avoid detection errors for the PCFICH of the carrier so as to be able to solve the HARQ buffer corruption problem caused by PCFICH detection errors.
