Embodiment Construction

[0088] As mentioned above, the current PDCCH transmission method has the problem of low reliability, and cannot meet the reliability requirements of the three major scenarios of 5G, especially the URLLC scenario.

[0089] In order to solve the above problems, an embodiment of the present invention provides a method for sending a physical downlink control channel. In the method, the base station configures the physical downlink control channel for multiple repeated transmissions, and the user equipment correspondingly multiple times according to the configuration information Repeatedly receiving the physical downlink control channel, and then combining the repeatedly received physical downlink control channels as the receiving result of the physical downlink control channel. Since the physical downlink control channel can be received multiple times, and the multiple received physical downlink control channels are mutually compensated for reference, the reception reliability of t...

Abstract

The invention discloses a sending and receiving method and device of a physical downlink control channel, equipment and a base station. The sending method comprises the following steps: receiving configuration information of the physical downlink control channel by the base station, wherein the configuration information comprises that the base station configures the physical downlink control channel for transmission with the maximum repetition frequency N, N is a positive integer, and N is greater than or equal to 2; correspondingly and repeatedly receiving the physical downlink control channel for multiple times according to the configuration information; and combining the repeatedly received physical downlink control channels for multiple times to serve as receiving results of the physical downlink control channels. By adopting the scheme, the transmission reliability of the physical downlink control channel can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method, device, device and base station for sending and receiving a physical downlink control channel. Background technique [0002] The 3GPP meeting defined three major scenarios of 5G: enhanced mobile broadband (Enhance Mobile Broadband, eMBB) business scenario, massive machine type of communication (mMTC) and low-latency, high-reliability communication (Ultra Reliable&Low Latency Communication) , URLLC). eMBB mainly corresponds to 3D / ultra-high-definition video and other high-traffic mobile broadband services; mMTC, which completely overlaps with NB-IOT applications, serves low-consumption and large-connection network services; URLLC mainly serves low-latency services such as unmanned driving and industrial automation , Highly reliable connected intelligent network services. [0003] Currently, in a New Radio (NR) system, before a user equipment (Us...
