Background
With the rapid development of the 4G TD-LTE technology, mobile 4G service application has become an increasingly important helper in people's work and life. In the TD-LTE system, because uplink subframes are relatively few (under the condition that the ratio of uplink subframes to downlink subframes in the current TD-LTE network is 1: 3, only 2 uplink subframes are in one radio frame), the uplink service performance is greatly affected, and therefore, the scheduling problem of limited uplink resources is more and more concerned by people.
In the TD-LTE system, if a user terminal has only downlink traffic scheduling and no Uplink traffic scheduling, the user terminal will not be allocated Physical Uplink Shared Channel (PUSCH) resource for transmitting Uplink traffic data in the current subframe, and the user terminal transmits Uplink L1/L2 Control information through a Physical Uplink Control Channel (PUCCH), and performs Hybrid Automatic Repeat request feedback (HARQ ACK/NACK) on the downlink traffic data to occupy PUCCH resource, under the existing technical condition, a fixed resource is generally reserved in the PUCCH for HARQ/ACK NACK, but if there is Uplink traffic scheduling in most user terminals in the cell and downlink traffic scheduling is not performed only, the PUCCH resource reserved for HARQ ACK/NACK is always fixed, uplink resource waste can be caused, and uplink service performance of the TD-LTE system is influenced.
Therefore, how to provide a scheduling method of uplink resources to improve the performance of uplink services is an important issue to be solved in the industry.
