Abstract: A communication method includes that when there is a data transmission requirement between two slave devices in a short-range wireless communication system, any one of the two slave devices may send a communication request to a master device such that the master device allocates an air interface resource for data transmission between the two slave devices, and the two slave devices can perform data transmission based on the air interface resource allocated by the master device.

Abstract: In a resource allocation method, a master control device establishes a first asynchronous connection link with a first slave device. The master control device establishes a first synchronous connection link with the first slave device based on the first asynchronous connection link. The master control device dynamically allocates a first air interface resource to the first asynchronous connection link based on indication information in a data packet transmitted on the first synchronous connection link. The indication information indicates whether control signaling transmission needs to be performed on the first asynchronous connection link.

Abstract: An electronic device includes a first graphics processing subsystem, a second graphics processing subsystem, and a screen. The first graphics processing subsystem includes a first application processor, a first graphics processing unit, and a first memory. The second graphics processing subsystem includes a second application processor, a second graphics processing unit, and a second memory. The first graphics processing unit renders a first GUI. The screen displays the first GUI. The second graphics processing unit renders a second GUI, and the second GUI and the first GUI belong to different interface types. The screen displays the second GUI. A display processing method applied to the electronic device is also provided, wherein the first graphics processing subsystem can be switched to the second graphics processing subsystem based on complexity of a to-be-displayed GUI.

Abstract: A short-range wireless communication method includes a sending device configured to broadcast a data packet; the sending device performs, at a predetermined time point within a time periodicity associated with the broadcasting of the data packet and in a predetermined frequency range, detection on response information fed back by at least one receiving device based on reception of the data packet, where the response information indicates at least a message that the data packet is not successfully received by any one of the at least one receiving device; and the sending device retransmits the data packet if the response information is obtained through detection.

Abstract: A method and associated apparatus provide for a management node to send to a terminal node, a negotiation request used to update a receiving/sending switching interval to first switching time. The receiving/sending switching interval includes a first receiving/sending switching interval of the management node and a second receiving/sending switching interval of the terminal node. The terminal node receives the negotiation request, feeds back acknowledgment response information to the management node in response to the negotiation request, and updates the second receiving/sending switching interval to the first switching time. The management node receives the acknowledgment response information. The management node updates the first receiving/sending switching interval to the first switching time based on the acknowledgment response information.

Abstract: In a multi-connection scenario, a main control node allocates a first time resource and a second time resource to a first secondary node and a second secondary node, respectively. The first time resource does not overlap the second time resource in a time period. The main control node sends a first resource parameter indicating the first time resource and a second resource parameter indicating the second time resource to the first secondary node and the second secondary node respectively. Based on the received resource parameters, the first secondary node and the second secondary node respectively perform communication in the time period by using the first time resource and the second time resource.
