Abstract

The present application provides a method and device for determining a detection range of a control channel in a multi-beam system. The method includes: a network device sends configuration information to a terminal device, where the configuration information is used by the terminal device to determine a target downlink period according to the configuration information Time domain resources that need to perform control channel detection within the time domain resources include multiple time domain scheduling units. In the method for determining the detection range of a control channel in a multi-beam system according to the embodiment of the present application, the terminal device only needs to detect the control channel on the time domain resources determined according to the configuration information, and for those control channels that are determined not to exist in the current beam Time domain resources (such as the time domain scheduling unit where other beam synchronization signals or broadcast signals are located) can be excluded through the configuration information, so that the terminal can avoid detecting this part of the time domain resources, thereby reducing the complexity of the terminal equipment and battery. power consumption.

Description

[0001] This application is a divisional application of an application with an application date of March 23, 2017, an application number of 2017800886207, and an invention titled "Method and device for determining the detection range of a control channel in a multi-beam system". " technical field [0002] The embodiments of the present application relate to the communication field, and more specifically, to a method and device for determining a detection range of a control channel in a multi-beam system. Background technique [0003] In the Long Term Evolution (LTE) system, the time domain position of the Physical Downlink Control Channel (PDCCH) is completely fixed, and it is located at the first few symbols of each 1ms subframe. The PDCCH can be received by performing blind detection within a few symbols. [0004] While future communication systems (for example, 5 th Generation, 5G) will introduce multi-beam (multi-beam) technology in the high-frequency band (>6GHz), ...
