Title:
METHOD, APPARATUS, AND BASE STATION FOR DATA SCHEDULING IN LTE-TDD SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/107195
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention is a method for data scheduling in an LTE-TDD system, the method comprising: a base station implements resource allocation for a first terminal UE, the resource allocation comprising nulling a preset number of uplink sub-frames after a specific sub-frame, and the first UE being located outside a preset distance range from the base station; and, on the basis of the resource allocation results, the base station implements scheduling of the uplink data frames from the first UE. The base station in the present invention nulls the preset number of sub-frames following the specific sub-frame by means of not scheduling the preset number of uplink sub-frames following a specific sub-frame from the terminal, thereby extending the time slot occupied by the specific sub-frame, enabling the system to accommodate a longer time advance TA, and achieving the objective of supporting long-distance coverage.
