Abstract: A method includes: a second terminal apparatus receives first indication information from a first terminal apparatus, where the first indication information indicates that the first terminal apparatus requests to send data to a network device. The second terminal apparatus may further send second indication information to the network device, where the second indication information may indicate that the first terminal apparatus sends the data to the network device. Therefore, the network device may learn, based on the second indication information from the second terminal apparatus, that the first terminal apparatus is to send uplink data, to avoid blind detection performed by the network device due to uncertainty about whether there is uplink transmission of the first terminal apparatus, so that receiving performance of the network device can be improved, and processing complexity of the network device can be reduced.

Abstract: An antenna and a mobile terminal are provided. At least two slots are disposed in a metal bezel of the mobile terminal, and the two slots divide the metal bezel into three metal sections. A radiating element of the antenna includes a second metal section located between the two slots, a first conductor, and a second conductor. The first conductor and the second conductor are separately connected to the second metal section. A feed point is connected to the first conductor by using a matching network. A ground point is connected to the second conductor to form a loop antenna. An electrical length path of a current from the feed point to the second metal section is not equal to an electrical length path of a current from the ground point to the second metal section.
