Claim of US Patent No. 11,071,117


1. A resource determination method performed by a mobile station, comprising:determining a first mobile station group to which a mobile station belongs from a plurality of mobile station groups corresponding to a base station to which the mobile station is connected;
obtaining a first resource configuration and a resource offset set used for uplink transmission for the first mobile station group;
selecting a first time resource candidate offset from a plurality of resource candidate offsets included in the resource offset set;
determining uplink transmission resources of the mobile station according to the first resource configuration and the first resource candidate offset;
transmitting information to the base station according to the determined uplink transmission resources; and
determining a resource configuration used for uplink transmission for each mobile station group in a plurality of mobile station groups corresponding to the base station according to a channel state corresponding to the mobile station group,
wherein, determining the first mobile station group to which a mobile station belongs from a plurality of mobile station groups corresponding to a base station to which the mobile station is connected comprises:determining the channel state of the mobile station according to a path loss, and further
determining the first mobile station group to which the mobile station belongs according to the channel states, and

wherein, when a path loss of the first mobile station group is smaller than a path loss of a second mobile station group in the plurality of mobile station groups, first time resources indicated by the first resource configuration are less than second time resources indicated by a second resource configuration used for uplink transmission for the first mobile station group, and first frequency resources indicated by the first resource configuration are more than the second frequency resources indicated by the second resource configuration.
