Abstract

The present disclosure provides a data transmission method and a communications device. The method includes: determining a first transmission manner of a first physical channel, where the first transmission manner is a manner in which data transmission is performed on the first physical channel; and determining a second transmission manner of a second physical channel according to the first transmission manner, where the second transmission manner is a manner in which data transmission is performed on the second physical channel. It is implemented that a transmission manner of a physical channel different from the first physical channel is determined according to the transmission manner of the first physical channel, and therefore it is implemented that different transmission manners are applied to different channels.

Claims

1. A method at a user equipment, comprising:

receiving a physical downlink control channel from a base station;

determining an index of a repetition number of the physical downlink control channel; and

determining a repetition number of a physical downlink shared channel that bears broadcast or multicast data according to the index of the repetition number of the physical downlink control channel, wherein the determining the repetition number comprises;

determining the repetition number of the physical downlink shared channel that bears broadcast or multicast data is (n1) times if the index of the repetition number of the physical downlink control channel indicates an (n1+k1+1)-times repetition of the physical downlink control channel, wherein k1 is an integer and n1 is a positive integer;

wherein if a frame structure type is frequency division duplex or half-frequency division duplex, and a category of the UE is a nonzero value, k1 is 0; and

wherein if the category of the UE is 0 and the frame structure type is time division duplex, k1 is −

2; and

wherein the method further comprises receiving the physical downlink shared channel from the base station based on the repetition number of the physical downlink shared channel.
