Claims17
A method for receiving information, performed by a terminal device, the method comprising:
- receiving first indication signaling sent by a network device, wherein the first indication signaling comprises a first indication field, the first indication field is configured to indicate a transmission mode and a transmission number of a physical downlink control channel (PDCCH), and the transmission number corresponds to candidate number sets for a first number;
- determining a search unit for control channel elements (CCEs) according to the candidate number sets;
- searching for each PDCCH candidate on the PDCCH by using the search unit;
- determining a target PDCCH candidate carrying downlink control information (DCI) to the terminal device, and determining a number of the CCEs occupied by the target PDCCH candidate as the first number, wherein the first number comprises a single value, and the single value is configured to indicate a number of the CCEs occupied respectively by the DCI transmitted in at least two beam directions;
- determining a second number according to the first number and the transmission mode of the PDCCH, wherein the second number is an integer multiple of the single value;
- and
- receiving the DCI according to the first number and the second number.
