Abstract: This application provides a system information redundancy version determining method and apparatus. A communications device determines at least one time-domain resource unit Ux, and determines a redundancy version RVx for system information on the time-domain resource unit Ux according to the time-domain resource unit Ux, where x is an identifier of the time-domain resource unit, the redundancy version RVx satisfies RVx=(Int1(X1/X2*(Int2(x/M) mod K))) mod L, x is a non-negative integer, X1 and X2 are non-zero real numbers, M is a positive real number, K and L are positive integers, mod indicates a modulo operation, Int1 indicates rounding up or rounding down, and Intl indicates rounding up or rounding down.

Abstract: This application discloses a paging method and apparatus. The method includes: receiving, by a network device, a random access preamble from a terminal device, where the random access preamble is used to request a paging message; obtaining, by the network device, a paging identifier associated with the random access preamble; and sending, by the network device, a paging message to the terminal device based on the paging identifier.

Abstract: The present disclosure provides a downlink data transmission method, including: using a time-division multiplexing transmission mode in one transmission time interval; sending, by using a wide beam, a control signal to a user served in the current transmission time interval; and grouping users and sending data signals to different user groups by using different narrow beams. In one transmission time interval, time-division multiplexing is used, and a wide beam and a narrow beam are respectively used to transmit a control signal and a data signal. This can avoid a throughput bottleneck resulting from use of a transmission scheme that is based on frequency-division multiplexing only.
