Abstract

A communication method and device. In the method, the terminal device may receive a received paging message of a non-serving beam (e.g., a second beam) in case of camping on the serving beam (e.g., the first beam). Thus, even if the signal quality of the service beam is poor and/or even if the terminal device is in a blocked scene, the terminal device can still successfully receive the paging message from the non-service beam, which is beneficial to improving the success rate of the terminal device for receiving the paging message, namely improving the call-through rate of the terminal device.

Description

Communication method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus. Background In a communication system, when a network device needs to perform data transmission or communication with a terminal device, the network device needs to send a paging message to the terminal device, and the terminal device can establish a wireless link between the network device and the terminal device in response to the paging message, thereby performing data transmission or communication, and the like. However, the problems that the signal of the network device is weak, or the terminal device is affected by the obstruction in the environment may cause that the terminal device cannot successfully receive the paging message, i.e. the success rate of the terminal device receiving the paging message is low. For example, in the case of a call, the user may not be able to successfully receive the paging message, i.e. the call rate is low, and the user experience is affected, because the user may plunger the terminal device or place the terminal device in an environment such as physical shielding, which is affected by a large penetration loss. It can be seen that the success rate of receiving the paging message is to be improved. Disclosure of Invention The application provides a communication method and a communication device, which are used for improving the success rate of receiving paging messages. In a first aspect, an embodiment of the present application provides a communication method. The method can be applied to the first terminal apparatus side. The first terminal device side may be the first terminal device itself, a module in the first terminal device, or a logic module or software capable of realizing all or part of the functions of the first terminal device. The module in the first terminal device is, for example, a software module, a hardware module or a combination of software and hardware module in the first terminal device, where the hardware module in the first terminal device is specifically a processor, a communication module, or a circuit or a chip responsible for communication functions, etc. A chip such as a modem (modem) chip, also known as a baseband (baseband) chip, or a system on chip (SoC) chip or a system in package (SYSTEMIN PACKAGE, SIP) chip containing a modem core, etc. Hereinafter, the first terminal apparatus side is exemplified as the first terminal apparatus. The method includes residing in a first beam, the first beam being a serving beam for a first terminal device, and receiving a paging message from a second beam, the second beam being a non-serving beam for the first terminal device, the paging message being for paging the first terminal device. In the embodiment of the application, the first terminal device can receive the paging message through the non-service beam (such as the second beam), so that even if the signal quality of the service beam is poor and/or the signal of the service beam is blocked, the first terminal device can successfully receive the paging message from the second beam, thereby being beneficial to improving the success rate of the first terminal device for receiving the paging message, being beneficial to smoothly establishing a wireless link between the first terminal device and a network side, being beneficial to carrying out services such as data transmission or conversation, and the like and improving user experience. If the call is in the case of a call, the call rate of the terminal device can be improved by the method provided by the embodiment of the application. In a possible embodiment, the method further comprises receiving a first signal from the second beam, the first signal being used to determine a compensation parameter for achieving downlink synchronization of the second beam with the first terminal device. For example, the first terminal device may implement downlink synchronization with the second beam based on the compensation parameter to receive the paging message from the second beam. Optionally, the first signal is, for example, a synchronization signal or a cell reference signal, etc. In this way, the first terminal device can realize downlink synchronization with the second beam, so as to improve the success rate of the first terminal device receiving the paging message from the second beam. In a possible embodiment, the method further comprises receiving first information from the second beam, the first information indicating a first resource, the first resource being used for the second beam to transmit the paging message. The first information is carried in the system information, for example. In this way, the first terminal device and the second beam are enabled to agree on resources for transmitting paging messages. In a possible implementation, the paging message is received if the first beam satisfies a first condition
