Abstract: The present disclosure relates to information transmission methods and apparatus. In one example method, a terminal obtains first spatial parameter information of a first channel. The terminal receives the first channel based on the first spatial parameter information. The first channel is one of multiple candidate control channels in a first control resource set. The first control resource set is configured by using a master information block (MIB), a system information block type 1 (SIB 1), or a physical downlink control channel (PDCCH) common configuration parameter.

Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

Abstract: The present disclosure relates to data error correction methods and apparatuses. One example method is applied to to-be-corrected data in a storage medium. Column check information is set for the to-be-corrected data, and the column check information includes check data of each column of data in the to-be-corrected data. The example method includes determining that first-row data in to-be-corrected data includes an uncorrected error, and performing error correction on each column of data in the to-be-corrected data based on column check information of the to-be-corrected data, where each column of data includes one bit of data in the first-row data. For each bit of data in the first-row data, if the bit of data is incorrect, after error correction is performed on a column in which the bit of data is located, the bit of data is corrected.
