Embodiment Construction

[0060] In order to facilitate understanding, some descriptions of concepts related to the present application are given by way of example for reference. As follows:

[0061] BWP: refers to part of the frequency domain resources within the carrier bandwidth allocated by the base station to the terminal. The size of the BWP is less than or equal to the bandwidth capability of the terminal, that is, the maximum bandwidth supported by the terminal. And the BWP can be a continuous frequency domain resource, for example, the BWP can include multiple continuous subcarriers, such as Figure 1A As shown, each subband (subband 0 or subband 1 or subband 2) can be a BWP. For another example, the BWP may include multiple consecutive physical resource blocks (physical resource blocks, PRBs). The terminal can support multiple BWPs, that is, the base station can configure multiple BWPs for the terminal. When multiple BWPs are configured, the BWPs may or may not overlap. On the downlink, t...

Abstract

The embodiment of the invention discloses a method for detecting downlink control information, terminal equipment and network equipment, relates to the field of communication, and can solve the problem of poor service experience caused by blind detection of DCI (Downlink Control Information) under a plurality of activated BWP (Broadband Wireless Premise) scenes in the prior art. The method comprises that: a terminal device receives detection related information of a network device for detecting downlink control information (DCI) of each BWP, the detection related information is determined by the network device according to resource load of a control resource set of each BWP, and the terminal device detects each DCI according to the detection related information. The embodiment of the invention is used for detecting the DCI of a plurality of BWPs.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201710996490.9 and the application title "A Method for Detecting Downlink Control Information" submitted to the China Patent Office on October 24, 2017, the entire contents of which are incorporated by reference in this application middle. technical field [0002] The present application relates to the communication field, and in particular to a method for detecting downlink control information, a terminal device and a network device. Background technique [0003] In order to better meet the growing demand for service types, new access technologies, such as New Radio (NR) technology can support multiple service types, and each service type is specific to systems such as subcarrier spacing, symbol length, and time units. The requirements for parameters are different, so flexible carrier spacing, symbol length, and time unit configuration of system parameters are considere...
