Abstract

The invention discloses a resource scheduling method and user equipment. The resource scheduling method comprises the following steps that: the user equipment receives an upper-layer signaling transmitted by a network side, wherein the upper-layer signaling is used for indicating the user equipment to enter a TTI bundling mode and a semi-static scheduling mode; and the user equipment activates the TTI bundling mode and the semi-static scheduling mode and communicates with the network side in the semi-static scheduling mode by taking TTI bundling as a unit. Through the method and the user equipment, the capacity of a TDD system can be improved and the signaling cost can be lowered so as to improve the performance of the system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a resource scheduling method and user equipment. Background technique [0002] The long term evolution (referred to as LTE) system uses a dynamic scheduling algorithm and a semi-persistent scheduling (Semi-persistent scheduling, referred to as SPS) algorithm for resource scheduling, wherein the dynamic scheduling algorithm means that both initial transmission and retransmission use A scheduling method for dynamic resources. The semi-static scheduling algorithm refers to a scheduling method that uses static resources for initial transmission and dynamic resources for retransmission. The allocation of dynamic resources needs to cooperate with relevant control signaling. Since the channel for transmitting control signaling is limited, the capacity of the LTE system will be limited by the capacity of the control signaling channel. If the capacity of the control...
