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

The embodiment of the invention provides a communication method and device, and is applied to the field of paging. The method comprises the following steps that: terminal equipment receives first indication information from access network equipment, according to the first indication information, the terminal equipment determines a target BWP from a plurality of initial bandwidth areas BWPs, the initial BWP is used for paging terminal equipment which does not establish radio resource control RRC connection with the access network equipment, and the terminal equipment monitors a paging message on the target BWP. According to the communication method provided by the embodiment of the invention, when a plurality of initial BWPs exist in one communication system, the terminal equipment can determine that the target BWP resides, and the access network equipment sends the paging message to the terminal equipment on the target BWP, so that the load balance and accurate 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...
