Abstract: An uplink transmission method and a terminal applied to the field of communications technologies to resolve a signal transmission problem that arises when a short-duration physical uplink control channel carrying only a scheduling request (SR) collides with another uplink channel on a same time domain resource. The method includes transmitting a scheduling request on a first uplink channel using a first time domain resource a first transmit power, where the first uplink channel comprises a first time domain resource and transmitting information on a second uplink channel using a second transmit power, where the second uplink channel comprises the first time domain resource, and where the first time domain resource represents some or all time domain resources in the second uplink channel.

Abstract: A communication method includes that, when a terminal device receives indication information used by a network device to indicate the terminal device to work on a non-dormant bandwidth part (BWP) in a secondary cell, the terminal device can determine a specific BWP on which the terminal device is to work, and perform a corresponding operation. A network device generates indication information, and sends the indication information to a terminal device, where the indication information is used to indicate the terminal device to work on a non-dormant BWP in a first secondary cell. Then, the terminal device enables, according to the indication information, the terminal device to work on a first BWP, where the first BWP is the non-dormant BWP in the first secondary cell.

Abstract: A data transmission method includes transmitting, by a first communications apparatus, first data with a second communications apparatus on a first frequency resource. The method also includes sending, by the first communications apparatus, control information to the second communications apparatus. The control information is used to schedule a part or all of the first data transmitted between the first communications apparatus and the second communications apparatus on a second frequency resource. A first transmission mode supported by the first frequency resource is different from a second transmission mode supported by the second frequency resource. Alternatively, the first transmission mode is the same as the second transmission mode, and a first feedback quantity supported by the first frequency resource is different from a second feedback quantity supported by the second frequency resource.
