Abstract: This application relates to time frequency synchronization-based positioning methods and apparatuses. In an example method, a first device completes time-frequency synchronization with a second device via a narrowband system, to obtain time-frequency synchronization information. The first device performs positioning between the first device and the second device via a wideband system when the first device determines, at a media access control (MAC) layer, that the time-frequency synchronization information reaches time-frequency precision associated with the wideband system. The first device exchanges a positioning result with the second device via the narrowband system.

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.

Abstract: This application discloses a data transmission method and apparatus, and relates to the field of short-range wireless communication technologies. In this application, a master device transmits data with slave devices based on an event cycle. Each event cycle includes a first sub-cycle and a second sub-cycle. In the first sub-cycle, the master device transmits data to each slave device, and receives indication information fed back by each slave device based on a data receiving status of the slave device. A retransmission slot is dynamically configured for each slave device in the second sub-cycle based on the indication information of the slave device in the first sub-cycle, so that retransmission slots corresponding to all slave devices in the second sub-cycle can be consecutive slots, and remaining slots in the second sub-cycle are also consecutive slots. This helps effectively use the remaining slots and reduce a waste of air interface resources.

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: 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: This application relates to a resource negotiation method and apparatus, a device, a computer-readable storage medium, and a computer program product. In an example method, a first primary device obtains, through a secondary device, resource allocation information provided by a second primary device. The resource allocation information indicates at least a time resource for transmission from the first primary device or the second primary device to the secondary device. The first primary device determines, in an event periodicity based on the obtained resource allocation information, a first time resource for transmission from the first primary device to the secondary 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.
