Embodiment 1

[0135] See figure 1 , the embodiment of the present invention provides a method for determining whether to continue to detect the downlink control channel, which can be applied to the terminal, wherein the process of the method can be described as follows:

[0136] S10: The terminal obtains first downlink control information DCI;

[0137] S20: The terminal determines whether to continue detecting the downlink control channel based on the first DCI.

[0138] In S10, the terminal may obtain the first DCI from the base station, where the first DCI may be carried by a downlink control channel, and the downlink control information DCI may include uplink and downlink resource allocation, hybrid automatic repeatrequest (Hybrid Automatic RepeatreQuest, HARQ), power control and other information.

[0139] Optionally, the terminal may obtain the first DCI from the base station in but not limited to the following two ways.

[0140] Manner 1: The terminal may obtain the first DCI on a ...

Embodiment 2

[0189] See Figure 4 , the embodiment of the present invention also provides a method for determining whether to continue to detect the downlink control channel, the process of the method can be described as follows:

[0190] S100: Based on the third blind detection indication information carried in the high-level signaling, the terminal determines the number of DCIs in the second preset downlink control information format DCI format that needs to be received within each monitoring oassion;

[0191] S200: After successfully receiving a DCI in the second preset DCI format, the terminal judges whether to continue to detect the downlink control channel in the same monitoring opassion according to the second preset DCI format. In this method, the terminal knows the number of DCIs in the DCI format that it needs to receive before performing blind detection on the downlink control channel.

[0192] That is, the third blind detection indication information carried in the high-level ...

Embodiment 3

[0202] Based on the same inventive concept, an embodiment of the present invention also provides a method for determining whether to continue detecting the downlink control channel, which is applied to a base station, and the method includes:

[0203] The base station sends the first downlink control information DCI to the terminal, so that the terminal determines whether to continue detecting the downlink control channel based on the first DCI after obtaining the first DCI.

[0204] Optionally, if the base station sends the first DCI to the terminal through a common downlink control channel or a group of common downlink control channels, the first DCI carries at least one blind detection indication information, and the at least one blind detection Each piece of blind detection indication information in the indication information is used to indicate the number of DCIs that need to be received by the preset DCI format of the corresponding terminal in the UE-specific search space...

Abstract

The embodiment of the invention provides a method for determining whether to continuously detect a downlink control channel, a terminal and a base station so as to solve the technical problem how to determine whether to continuously carry out blind test according to a specified DCI (Downlink Control Information) format after DCI of the specified DCI format is successfully received and the technical problem of no definite scheme in the prior art. The method for determining whether to continuously detect the downlink control channel comprises the steps that: the terminal acquires first DCI; andthe terminal determines whether to continuously detect the downlink control channel on the basis of the first DCI.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for determining whether to continue detecting downlink control channels, a terminal and a base station. Background technique [0002] The mobile Internet is subverting the traditional mobile communication business model, providing users with unprecedented experience, and profoundly affecting all aspects of people's work and life. The mobile Internet will promote the further upgrading of information interaction methods in human society, and provide users with richer business experiences such as augmented reality, virtual reality, ultra-high-definition (3D) video, and mobile cloud. The further development of the mobile Internet will bring about a thousand-fold increase in mobile traffic in the future, and promote a new round of changes in mobile communication technology and industry. The Internet of Things expands the service scope of mobile communication, extending from human-t...
