Provided by the present disclosure are data transmission method and device. In an embodiment of the present disclosure, data transmission conditions of each serving cell among at least two serving cells is detected by means of a terminal so that the terminal may, according to the data transmission conditions of each serving cell, execute random access on a serving cell experiencing wave beam failure so as to update a service beam of the serving cell. Thus, when the terminal experiences wave beam failure in a serving cell in a carrier aggregation (CA) scenario, reliable data transmission may be achieved, and the reliability of data transmission may be effectively ensured.

Wireless network operations can choose a long-term evolution (LTE) and 5G new radio (NR) dual connectivity deployment architecture using LTE as the anchor radio access network (RAN) node and adding mmWave NR as a secondary node when available. However, dual LTE/NR radios can consume more power and contribute more heat, thus degrading performance of radio frequency components. The overheating can be addressed by the user equipment (UE) sending an information message to indicate areas in which it requests to operate with reduced capability. Consequently, the network can determine whether to grant the request, or the UE can switch between NR to LTE depending on NR downlink channel quality.

In a data packet transmission method disclosed herein, a capability information value indicating an amount of data that can be supported by a data transmission end is determined. In response to determining that a data packet is not received correctly, a data packet to be retransmitted is determined and is retransmitted according to the capability information value.

A search space monitoring method and a device are disclosed. The method is executed by a terminal device, and a plurality of transmission objects are configured for the terminal device. The method includes: obtaining scheduling configuration information; and monitoring an SS based on the scheduling configuration information, where the SS includes an SS in which at least two transmission objects schedule one transmission object.

Techniques for performing data exchanges during voice call sessions is described. In one example, a network server may facilitate a voice call session between user devices and associate a unique session number (USN) to each of the voice call sessions. The USN may be used as a reference when toggling between voice call sessions. In one example, when a particular voice call session is toggled to an active state, the network server may limit recipients of sensitive financial information to be between transacting parties in the active voice call session. By isolating other user devices that are not privy to transactions in the active voice call session, the chances for a transacting party in the active voice call session to accidentally send payments, for example, to an unintended recipient can be substantially minimized.
