Abstract

Method for configuring frame structure, user equipment and network equipment are provided. The method includes: configuring a group of time intervals X and generating configuration information of the group of time intervals X according to a channel condition and communication service demand; adding the configuration information of the group of time intervals X to downlink control information which is carried in a predetermined resource unit; and transmitting the predetermined resource unit to a UE, to indicate the UE to perform data transmission with a network based on the group of time intervals X. In this way, the configuration of the frame structure including the time intervals X is indicated, so that the network and the UE can normally communicate with each other.

Dependent claims

A method for configuring a frame structure, comprising:

configuring a group of time intervals X and generating configuration information of the group of time intervals X according to a channel condition and communication service demand;
adding the configuration information of the group of time intervals X to downlink control information which is carried in a predetermined resource unit;
and
transmitting the predetermined resource unit to a user equipment (UE), to indicate the UE to perform data transmission with a network based on the group of time intervals X,
wherein the predetermined resource unit comprises one of a downlink control part, a downlink transmission part and a time interval X, where the downlink transmission part comprises at least one downlink control part, and the time interval X comprises at least one downlink control part,
wherein when length of the time interval X is fixed, configuring the time interval X comprises:
when the time interval X belongs to type 1, configuring length of a downlink transmission part in the time interval X or length of a guard period in the time interval X, where the length of the downlink transmission part is adapted to be configured by a terminal symbol index of the downlink transmission part;
when the time interval X belongs to type 2, configuring length of an uplink transmission part in the time interval X or the length of the guard period in the time interval X, where the length of the uplink transmission part is adapted to be configured by an initial symbol index of the uplink transmission part;
