Embodiment Construction

[0013] In order to solve the technical problems raised in the background technology, the present invention adds an enhanced PDCCH control function to the LTE communication system. This function will be used in conjunction with frequency selective scheduling to improve the quality of DCI data transmission, thereby improving the reliability of PDCCH channel transmission of DCI data. Improve user awareness of downlink data services.

[0014] Such as figure 1 As shown, it is a schematic flow chart of a PDCCH scheduling method proposed by the present invention, including the following steps:

[0015] S101, the base station judges whether the enhanced physical downlink control channel PDCCH switch is turned on.

[0016] When the user performs downlink services, it first determines whether the terminal can perform periodic subband CQI reporting, and if the terminal enables periodic subband CQI reporting, then confirms whether to enable the enhanced PDCCH switch. Specifically, before t

Abstract

The invention discloses a PDCCH dispatching method. The method includes the steps that after an enhancing PDCCH switch is judged to be turned on by a base station, the sub-band of the maximum CQI is selected from all sub-bands of channel quality indicators (CQIs) reported by terminal UE and serves as a resource for bearing a frequency band of downlink control information (DCI), and first five PRBs in a PDSCH resource area where the frequency band starts are taken as frequency resources for fixedly bearing the DCI. The success rate of receiving PDCCHs by a terminal in the presence of disturbance is increased, and a reliable precondition is provided for accurately analyzing PDSCH service data, so that the quality of free-port data transmission is ensured, the handling capacity of a user is improved in comparison with an original implement method in the same environment, and then the maximization of the system capacity of a wireless communication system is ensured.
