Embodiment Construction

[0068] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0069] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as a terrestrial communication system, and a non-terrestrial communication system, such as a satellite communication system. Wherein, the satellite communication system can be integrated with the traditional mobile communication system. For example, the mobile communication system may be a 4th Generation (4G) communication system (for example, a long term evolution (LTE) system), a worldwide interoperability for microwave access (WiMAX) communication system , 5th Generation (5th Generation, 5G) communication systems (eg, new radio (new radio, NR) systems), and future mobile communication systems.

Abstract

The present application relates to the technical field of wireless communication, and discloses a communication method and device, which are used to solve the problem that the current terminal accesses network equipment for a long time. The terminal determines the first frequency point for accessing the network device. Then, according to the first frequency point, at least one second frequency point is determined, any second frequency point is different from the first frequency point, and at least two second frequency points are also different. At least two different second frequency points are selected from the first frequency point and at least one second frequency point, and within one time unit in one cycle, the at least two different frequency points are used to respectively receive the SSB from the network device. The terminal accesses the network device according to the received one or more different SSBs. A time unit uses different frequencies to receive different SSBs. The terminal may receive the SSB according to at least two different frequency points. The terminal can also receive the SSB configured by the network device in less time. Thus, the terminal can reduce the time for accessing the network device.

Description

technical field [0001] The embodiments of the present application relate to the field of wireless communication technologies, and in particular, to a communication method and apparatus. Background technique [0002] After the terminal device is powered on, it can receive a synchronization signal block (SSB) sent by the network device, and access the network device according to the SSB. The specific process can be as follows: [0003] Frequency points of multiple cells are configured in the network device, for example figure 1 As shown, the frequency point for accessing the cell is fc. It should be noted that the frequency point fc here actually refers to the SSB bandwidth of the frequency band with fc as the center frequency point, and the frequency band is abbreviated as frequency point fc here. The SSB bandwidth is a part of the cell bandwidth (Cell bandwidth). The network device uses the frequency point fc to transmit different SSBs in different time units. For examp...
