Abstract: This application provides a terminal device and a communication method. The terminal device is in a dual-connectivity network including a long term evolution (LTE) link and a new radio (NR) link, and when the terminal device detects that the terminal device is in a power saving mode, and/or when the terminal device detects that battery power of the terminal device is less than or equal to a first preset value, and/or when the terminal device detects that temperature of a rear cover of the terminal device is greater than or equal to a second preset value, the terminal device releases the NR link, and uses the LTE link for communication.

Abstract: Embodiments of this application provide a method for adjusting a quantity of data streams, a terminal, and a MIMO system. In this method, the terminal may actively negotiate the quantity of transport layers used in a downlink data transmission process with a network device based on an operation status of the terminal, so as to adaptively and dynamically adjust the quantity of data streams in the downlink data transmission process. This may reduce power consumption of the terminal and prolong a standby time of the terminal without affecting user experience while meeting requirements for a data transmission rate of the terminal.

Abstract: This application provides a terminal device and a wireless communications method. When the terminal device is in a dual connectivity network including an LTE link and an NR link, the terminal device determines, based on a service transmission rate related to an actual transmission rate, whether to disconnect the NR link. If the service transmission rate is relatively low, the terminal device disconnects the NR link. If the service transmission rate is relatively high, the terminal device does not disconnect a first link, and uses both the NR link and the LTE link for communication. In this way, power consumption of the terminal device can be effectively reduced without affecting the user experience on transmission rate, the user experience on power consumption is improved, and the user experiences on transmission rate and power consumption are balanced to some extent.
