Embodiment Construction

[0086] It should be understood that the terms "first" and "second" in the embodiments of the present application are used to distinguish similar objects, and not necessarily used to describe a specific sequence or sequence. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described.

[0087] First, the nouns involved in the embodiments of the present application are explained:

[0088] Machine type communication (MTC) is a machine-to-machine data communication that does not require human intervention. It has the characteristics of various business models and a large number of terminals. MTC includes core MTC and massive MTC. Among them, the core MTC is mainly used in low-latency, high-reliability application scenarios. Massive MTC is used to meet massive data connections and can be applied to the large-scale Inter...

Abstract

Embodiments of the present application provide a communication method and device, which are applied in the field of paging. The method includes: a terminal device receives first indication information from an access network device; according to the first indication information, the terminal device determines a target BWP from a plurality of initial bandwidth area BWPs, and the initial BWP is used for paging A terminal device that has not established a radio resource control RRC connection with the access network device; the terminal device monitors a paging message on the target BWP. In the communication method provided by the embodiment of the present application, when there are multiple initial BWPs in a communication system, the terminal device can determine the target BWP to camp on, and make the access network device send a paging message to the terminal device on the target BWP, In this way, the load balancing and precise paging of the initial BWP can be realized.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a communication method and device. Background technique [0002] The fifth generation mobile communication system (the 5 th generation (5G) new radio (new radio, NR) frequency band is wider than the long term evolution (long term evolution, LTE) frequency band. Different terminal devices have different radio frequency capabilities, resulting in different bandwidths supported by the terminal devices. Therefore, a concept of bandwidth part (BWP) needs to be introduced, and a part of frequency spectrum is allocated to a terminal device on a bandwidth, so as to adapt to the bandwidth that the terminal device can support. At the same time, by configuring multiple BWPs with different bandwidths for the terminal equipment, flexible scheduling and energy-saving control of the terminal equipment can also be realized. [0003] The initial bandwidth part (initi...
