A first user equipment (UE) can determine a slot, from a resource pool including a plurality of slots allocated for sidelink communications, for providing hybrid automatic repeat request (HARQ) feedback to a second UE via a sidelink channel. The determination may be based on a physical slot index or a logical slot index. The first UE may send the HARQ feedback on the sidelink channel in the slot, or refrain from sending the HARQ feedback, based on the determination. The first UE may determine the slot has a first slot index that is at least a preconfigured number of slots after a slot scheduled for sidelink data transmission having a second slot index.

A terminal includes a security subsystem, a baseband processor, and a first bidirectional bus coupled between the security subsystem and the baseband processor. The security subsystem is configured to manage at least one of data related to a user identity or data related to network security in wireless communication, and exchange the data with the baseband processor by using the first bidirectional bus. The baseband processor is configured to exchange the data with the security subsystem by using the first bidirectional bus, and implement wireless communication by using the data. The security subsystem and the baseband processor are in the same hierarchy. The security subsystem may proactively perform data transmission by using the first bidirectional bus.

A control method that is achieved by a refrigerator application installed in portable terminal (110), the control method including the steps of instructing an operating system (OS) of portable terminal (110) to connect to a refrigerator in operation in a software access point mode, and sending a service set identifier (SSID) of an access point and a password for connecting to the access point to the refrigerator. An SSID of the refrigerator that operates in the software access point mode, and a password for connecting to the refrigerator that operates in the software access point mode are incorporated in the refrigerator application in advance.
