Embodiment Construction

[0086] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0087] Such as figure 1 As shown, the embodiment of the present invention provides a method for receiving a downlink control channel

[0088] Step 101: If the terminal does not receive the slow DCI, it receives the fast DCI according to a predefined method;

[0089] Step 102: The terminal transmits data according to the received fast DCI.

[0090] Optionally, the terminal receives the slow DCI in the Legacy Control Region, and receive...

Abstract

The invention discloses downlink control channel receiving and sending methods and devices. The downlink control channel receiving method provided in the embodiment of the invention comprises the steps that: a terminal receives fast DCI according to a predefined mode while not receiving slow DCI; and the terminal performs data transmission according to the received fast DCI. The terminal in the embodiment of the invention can continue receiving the fast DCI according to the predefined mode while not receiving the slow DCI, and further receive data according to the fast DCI; and thus, by meansof the embodiment of the invention, the fact that the terminal can continue receiving the fast DCI while not receiving the slow DCI and complete data transmission can be ensured.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for receiving and sending a downlink control channel. Background technique [0002] With the continuous emergence and enrichment of new business requirements such as augmented reality, virtual reality, ultra-high-definition video, and mobile cloud, higher performance requirements are put forward for future mobile communication systems, such as higher peak rates and better user experience. Speed, smaller delay, higher reliability, higher spectrum efficiency and higher energy efficiency, etc., and need to support more user access and use of various business types. In order to support a huge number of various terminal connections and different types of services, the flexible configuration of uplink and downlink resources has become a major trend in technology development. Future system resources can be divided into different subbands according to di...
