Abstract: A chip system includes a chip package body and an electromagnetic shielding enclosure. The chip package body is electrically connected to a circuit board through a first connection part. The chip package body includes a package substrate and at least one chip that are electrically connected. The electromagnetic shielding enclosure includes a conductive first shielding structure and a conductive second shielding structure. The first shielding structure is connected to the package substrate. A first cavity included in the first shielding structure is configured to accommodate at least one chip. A first end of the second shielding structure is connected to the circuit board or a solder pad of the circuit board; or a second end of the second shielding structure is connected to the first shielding structure to form a second cavity.

Abstract: This application relates to the field of communications technologies, and in particular, to uplink data sending and receiving methods, an apparatus, and a system. A sending method includes: receiving, by a terminal device, control information sent by a network device, where the control information is used to indicate the terminal device to send first data on a first resource: and when the first resource and a second resource to be used by the terminal device to send second data overlap in a first time domain range in time domain, stopping sending, by the terminal device on the first resource, the first data in the first time domain range, where a frequency domain range corresponding to the first resource belongs to a first carrier, and a frequency domain range corresponding to the second resource belongs to a second carrier. According to the foregoing technical solution, uplink data sending of the terminal device that does not support simultaneous data sending on resources of different carriers is effectively supported, and this helps avoid a conflict in the uplink data sending.

Abstract: This application provides a control information transmission method, and relates to the field of wireless communications. The method includes: determining, by a terminal device, whether to monitor an uplink preemption indication (PI) based on whether a time-frequency resource used to transmit uplink data overlaps a reference uplink resource (RUR), to effectively avoid blind detection performed on the uplink PI by terminal devices that do not need to receive the uplink PI, and reduce overheads of blind detection performed on the uplink PI by the terminal devices.

Abstract: An information transmission method and a related apparatus are provided. The method includes: transmitting, by a first device, a TB to a second device; and transmitting, to the second device before a feedback time corresponding to the TB, original data of a first CB included in the TB, where the first CB is a CB that meets a condition necessary for system bits being occupied. In this case, a waiting time for the first device to transmit the first CB is effectively shortened, and feedback overheads are reduced. Alternatively, the first device may directly transmit first indication information to the second device, and in this case, according to the first indication information, the second device may not directly transmit feedback information of the first CB, thereby effectively reducing feedback overheads. Alternatively, the first device may transmit original data of the first CB and first indication information to the second device, so that the first device can transmit the first CB to the second device in time, thereby further ensuring that feedback overheads are effectively reduced.
