Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] The embodiment of the present invention provides a method for sending downlink control information, and the sending method is used in a base station. The method for sending downlink control information in the embodiment of the present invention uses the correspondence between the aggregation level of the downlink control information and / or the number of blind detections corresponding to the aggregation level and the load size of the downlink control info...

Abstract

The present invention provides a method for sending downlink control information, a method for receiving it, and related equipment. The method for receiving includes: using the aggregation level of the downlink control information and / or the correspondence between the number of times of blind detection corresponding to the aggregation level and the load size of the downlink control information Determine the configuration information of the downlink control information to be sent; use the configuration information to configure the downlink control information to be sent; send the downlink control information to be sent to the mobile communication terminal. In the method for sending downlink control information provided by the present invention, the aggregation level of the downlink control information and / or the number of blind detections corresponding to the aggregation level are related to the load size of the downlink control information, which is different from the configuration of the downlink control information in the prior art. The load size of the downlink control information provides a new way of configuring the downlink control information, and improves the flexibility of configuring the downlink control information.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for sending, receiving and related equipment of downlink control information. Background technique [0002] PDCCH (Physical Downlink Shared Channel) can be used to indicate the PDSCH (Physical Downlink Shared Channel) scheduling corresponding to UE (User Equipment), or the PUSCH (Physical Uplink Shared Channel) to be sent , Physical uplink shared channel) scheduling time-frequency resources and transmission parameters, but to obtain this information, the UE needs to detect the PDCCH first. [0003] Since the PDCCH is sent by the base station, and the UE has not received other information except for some system information before, the UE does not know the number and location of the CCE (Control Channel Element) occupied by the PDCCH, and the transmitted DCI ( Downlink Control Information (Downlink Control Information) format, etc., therefore, PDCCH detection ...
