ADAPTATION OF CONTROL SIGNALING TRANSMISSIONS TO VARIATIONS IN RESPECTIVE RESOURCES

摘要

A method and an apparatus for a User Equipment (UE) to receive a first type of a Physical Downlink Control CHannel (PDCCH) or a second type of a PDCCH in a Transmission Time Interval (TTI) are provided whereby the first type of PDCCH and the second type of PDCCH convey respective Downlink Control Information (DCI) formats containing Cyclic Redundancy Check (CRC) bits scrambled with a Radio Network Temporary Identifier (RNTI). The method includes receiving by the UE a first bitmap associated with a number of TTIs equal to the first bitmap size, wherein each element of the first bitmap indicates whether a TTI is of a first type or of a second type, decoding by the UE only PDCCH of the first type if the TTI is of the first type, and decoding by the UE only PDCCH of the second type if the TTI is of the second type.
