#$%^&*AU2010201714B220120823.pdf#####ABSTRACT A method and a device for allocating downlink resources are provided. The method includes: determining a coverage range of a base station (BS); determining downlink resources to be reserved according to the coverage range; and allocating downlink resources 5 in the BS except for the downlink resources to be reserved to subscribers including ultra far subscribers. The device includes a determining unit, a calculating unit, and an allocating unit. Thus, the problem of correctly receiving downlink signals with the increase of round trip delay (RTD) in ultra far coverage is solved, so as to improve user satisfaction.1/5 Determine a coverage range of a BS101 Determine downlink resources to be reserved 102 according to the coverage range Allocate downlink resources in the BS except 103 for the downlink resources to be reserved to subscribers including ultra far subscribers FIG. 1 Determine a coverage range of a BS 201 according to network planning Determine downlink resources to be 202 reserved according to the coverage range Record a region formed by the downlink 203 resources Allocate the downlink resources in the 204 formed region to a part of or all of nonultra far subscribers Allocate downlink resources in the BS20 except for the downlink resources in the 205 region to other subscribers FIG. 2
