    Abstract: This application provides a resource indication method, a terminal device, and a network device. The method includes: determining time domain positions of demodulation reference signals (DMRSs) based on the mapping type of the physical shared channel and with reference to a position index of the last symbol occupied by the physical shared channel or a quantity of symbols occupied by the physical shared channel in the resource unit, where the position index of the last symbol occupied by the physical shared channel in the resource unit corresponds to the first type, and the quantity of symbols occupied by the physical shared channel in the resource unit corresponds to the second type.

    Abstract: This disclosure provides an information transmission method and a communications device. The method includes: when determining that higher layer signaling is not configured with a scrambling identifier, scrambling or descrambling, by a communications device, data by using a second initial scrambling value, where the scrambling identifier is used by the communications device to determine a first initial scrambling value used for data scrambling or descrambling, and the second initial scrambling value is related to at least one or two of a cell identifier, a radio network temporary identifier, and a reserved bit. Therefore, in the embodiments of this disclosure, when determining that the higher layer is not configured with the scrambling identifier, the communications device scrambles or descrambles the data by using the second initial scrambling value. This resolves a problem in the prior art that a terminal device cannot determine an initial scrambling value used for data scrambling.

    Abstract: The present disclosure relates to a method for sending cell common control reference information. In one example method, before common control information needs to be sent, a base station having M antenna ports generates the cell control reference information used to detect the common control information. The base station maps the common control information and the cell control reference information to one or more resource units (RUs) of N antenna ports. The N antenna ports are a subset of the M antenna ports. The base station uses the one or more RUs to send the common control information and the cell control reference information used to detect the common control information to a user equipment (UE) within a coverage area of the base station.

    Abstract: This application relates to the field of communications technologies, and discloses a transport block generation method and apparatus. The method includes: determining a TBS based on an MCS of a receiving device, a resource characteristic of an RB allocated to the receiving device, and a quantity of symbols, where the quantity of symbols is a quantity of symbols included in each RB, and each RB includes a same quantity of symbols; and generating a TB based on a TBS. TBS is determined based on the MCS of the receiving device, a quantity of RBs allocated to the receiving device, and the quantity of symbols included in the RB, and the TB is generated based on the determined TBS. The quantity of symbols included in the RB is considered in determining the TBS. Therefore, the determined TBS may vary with the quantity of symbols included in the RB.

    Abstract: This application describes a channel information feedback method and a communication apparatus. The method includes a terminal device that receives configuration information sent by a network device, where the configuration information is used to configure a feedback mode of channel information. The terminal device may feed back current channel information to the network device when the feedback mode configured by using the configuration information is a first mode. The terminal device may alternatively feeds back predicted channel information to the network device when the feedback mode configured by using the configuration information is a second mode. System performance is therefore improved by the method described in this application because channel information feedback requirements in different scenarios can be met. In particular, a problem that data transmission performance deteriorates because channel information expires in a moving scenario can be resolved by feeding back the predicted channel information.
