Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0061] In the embodiment of the present invention, the method for sending and obtaining system information can be applied to a system in which multiple BWPs are configured in the system bandwidth, such as eLTE, 4G or 5G systems. Specifically, the method for acquiring system information is applied to mobile communication terminals in the system, and the method for sending system information is applied to network devices in the system. The mobile communi...

Abstract

The invention provides a system information transmitting method and obtaining method and a related device. The system information transmitting method comprises the steps: receiving a system information request message sent by a mobile communication terminal; transmitting the system information on a first target BWP (bandwidth portion) of a plurality of BWPs forming a system bandwidth and / or a PDCCH (physical downlink control channel) indicating the resource location of the system information. The method standardizes the transmission and obtaining of the system information in one or more BWPs forming the system bandwidth.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for sending and acquiring system information and related equipment. Background technique [0002] In the mobile communication system, the maximum system bandwidth of 400MHz supported by the future communication system such as the fifth generation (5th-Generation, 5G) mobile communication system is much larger than that supported by the Long Term Evolution (LTE) system. The maximum system bandwidth is 20MHz to support greater system and user throughput. [0003] On the other hand, the 5G mobile communication system supports dynamic bandwidth allocation, and divides the system bandwidth into multiple bandwidth parts (Bandwidth Part, referred to as BWP) to support narrowband mobile communication terminals, or mobile communication terminals in energy-saving mode are only part of the system work on bandwidth. In addition, the 5G mobile communication system al...
