Description
Technical Field
The present invention relates to wireless communication technologies, and in particular, to a data scheduling method, a terminal, and a system.
Background
In a Long Term Evolution (LTE) system, when a User Equipment (UE) in a connected state has new uplink data to send, a Scheduling Request (SR) process is initiated, and the uplink data is sent after receiving an uplink Scheduling Grant (UL Grant) of a base station.
For the UE in idle state, uplink out of synchronization, or not allocated SR resources by the base station, a contention-based random access procedure needs to be initiated to acquire an UL Grant (allocated in the RAR) to send uplink data. The random access process based on competition can replace the function of SR to apply for uplink resource, and is suitable for the condition of low-density uplink resource request.
In the uplink data scheduling process based on SR and random access, the UE needs to send data after obtaining the UL Grant after a certain waiting time, and this scheduling-based data sending mechanism has the defects of long waiting time, high signaling overhead, and the like. For intermittent small data packet transmission, the mechanism has low data signaling and large data overhead per bit.
