Abstract

Disclosed by the present application are a data transmission method, device and apparatus, the method comprising: a terminal transmitting data to a base station by means of normal resources; when the base station adjusts the configuration of the normal resources so that the terminal transmits data when the normal resources are unavailable, or when the normal resources cannot complete a configured number of repeated transmissions, data is transmitted to the base station on potential resources, wherein the normal resources and the potential resources are resources used for transmitting data which are semi-statically configured for the terminal by the base station; and when the normal resources are unavailable and the potential resources do not serve as a third type of resource for other terminals, the base station and the terminal determine a potential resource for transmitting data that needs to be used according to the same mode.

Claims20

Dependent claims

A method for data transmission, comprising:

transmitting, by a terminal, data to a base station on one or more normal resources;
and
transmitting, by the terminal, the data to the base station on one or more potential resources, in response to that the base station adjusts a configuration for the normal resources and thus the normal resources are unable to be used for data transmission, or in response to that repeated transmissions with a configured quantity is unable to be completed on the normal resources;
wherein:
the normal resources and the potential resources are resources which are used for data transmission and semi-statically configured for the terminal by the base station, the potential resources are also a third type of resources between the base station and other terminals, and the third type of resources refers to resources dynamically scheduled by the base station to the other terminals;
and in response to that the normal resources are unavailable and the potential resources are not used by other terminals as the third type of resources, the terminal determines the potential resources to be used for data transmission in a same manner as the base station.

3 more elements

A terminal, comprising:

a processor configured to read a program in a memory to:
process data according to requirements of a transceiver;
and
the transceiver configured to receive and transmit the data under control of the processor, and configured to:
transmit the data to a base station on one or more normal resources;
and
transmit the data to the base station on one or more potential resources, in response to that the base station adjusts a configuration for the normal resources and thus the normal resources are unable to be used for data transmission, or in response to that repeated transmissions with a configured quantity is unable to be completed on the normal resources;
wherein the normal resources and the potential resources are resources which are used for data transmission and semi-statically configured for the terminal by the base station, and the potential resources are also resources between the base station and other terminals;
and in response to that the normal resources are unavailable and the potential resources are not used by other terminals as a third type of resources, the base station and the terminal determine the potential resources to be used for data transmission in the same manner, and the third type of resources refers to resources dynamically scheduled by the base station to the other terminals.
