    Abstract: A terminal receives downlink scheduling information of a downlink subframe F(i, j), where a set M of preconfigured downlink subframes in which the downlink subframe F(i, j) is located is divided into N subsets of preconfigured downlink subframes, a bit quantity of a hybrid automatic repeat request-acknowledgement HARQ-ACK that needs to be fed back for each downlink subframe in one subset of preconfigured downlink subframes is a predetermined value, and bit quantities of HARQ-ACKs that need to be fed back for any downlink subframes in different subsets of preconfigured downlink subframes are different. The terminal generates a HARQ-ACK codebook according to a receiving status of downlink data. And the terminal generates uplink control information after encoding the HARQ-ACK codebook; and a sending module sends the uplink control information.

    Abstract: This application provides a parameter determining method, a monitoring method, and a communications apparatus. The method includes: configuring, by a network device, a plurality of serving cells for a terminal, where at least two of the plurality of serving cells have different subcarrier spacings; and determining, by the network device based on at least one of subcarrier spacings of the plurality of serving cells, a maximum number of physical downlink control channel PDCCH candidates monitored by the terminal in a unit time. According to this application, a maximum number of PDCCH candidates monitored by a terminal in one time unit can be determined when carriers for carrier aggregation correspond to different subcarrier spacings.

    Abstract: The present disclosure provides a wireless network coverage enhancement method, apparatus, and system. The method includes: receiving, by a terminal, a downlink signal sent by a network device; determining, by the terminal, a first coverage level of the terminal according to the downlink signal; determining, by the terminal, an uplink communications parameter according to the first coverage level; and sending, by the terminal, an uplink signal to the network device according to the uplink communications parameter. According to the method in embodiments of the present invention, a probability of successfully receiving the uplink signal is improved. Therefore, the network device does not need to send a NACK to the terminal, so that overheads of an air interface between the terminal and the network device are reduced, a period in which the terminal performs coverage enhancement is shortened, and power consumption of the terminal is reduced.

    Abstract: This application provides a secondary cell control method and an apparatus. The method includes: A terminal device receives control information in a time unit n, where the control information may include an activation command for a first secondary cell or a deactivation command for a first secondary cell. When the control information includes the activation command for the first secondary cell, first information of the first secondary cell is sent in a time unit n+k, where k is determined based on a first frame structure parameter configured for the terminal device, and both n and k are positive integers. The first information may be a CSI report.
