Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: A service data pushing method is disclosed to prevent message pushing from affecting an operation that is currently performed in a device. The method includes establishing, by a second device, a communication connection with a first device according to triggering of a specified action, when the first device presents service push information; receiving, by the second device, related information of the service push information that is transmitted by the first device; and determining, by the second device, a pushing page corresponding to the service push information according to the related information, and presenting the pushing page to perform a corresponding service operation. The service push information is pushed by using the first device and is viewed by using the second device, so that video information currently played in the first device is not affected.
