Abstract

A method and a device for transmitting or receiving scheduling information are described. In the method for transmitting scheduling information, information about a scheduling result of resources to be occupied by one or more User Equipment (UEs) is acquired; and scheduling information including a first type of scheduling information and a second type of scheduling information is transmitted to the one or more UEs according to the information about the scheduling result. The first type of scheduling information includes information for parsing the second type of scheduling information, and the scheduling information determines a resource scheduling condition of the user.

7. The method as claimed in claim 1, wherein the first type of scheduling information further comprises a group number, wherein the group number is used to indicate a group to which the one or more UEs that are currently scheduled belong.

8. The method as claimed in claim 7, wherein grouping of the one or more UEs is implemented in at least one of the following manners:

determining a remainder after dividing an Association Identifier (AID) of each UE by the number of groups, and putting one or more UEs with the same remainders into the same group; and

putting one or more UEs whose predefined UE IDs begin with the same digits, the number of the digits being a predetermined number, into the same group.

9. The method as claimed in claim 1, wherein the second type of scheduling information comprises at least one of the following information:

user identifier information and resource position indicator information of user data;

wherein the user identifier information comprises AID and/or user Partial Association Identifier (PAID), and the resource position indicator information of the user data comprises frequency domain indicator information and/or time domain indicator information.
