Embodiment Construction

[0048] The embodiments of the present invention mainly provide a transmission method and a related device that allow the slave device to actively transmit packets without being restricted by the master device. Please note that in this embodiment, unless otherwise specified, the receiving time slots are all regarded as "Master-to-Slave" (Master-to-Slave) time slots, and the transmitting time slots are all regarded as "Slave-to-Master" (Slave-to -Master) time slot.

[0049] Please refer to figure 2 , figure 2 It is a schematic diagram of a process 20 of the present invention. The process 20 is used in a slave device of the Bluetooth system to implement an active transmission function in the field of packet switching (Packet Switched), so as to reduce wireless resource consumption. Process 20 includes the following steps:

[0050] Step 200: start.

[0051] Step 210: Set an active slot window on a communication time.

[0052] Step 220: Convert the receive slots ("master-sl...

Abstract

The invention provides a transmission method capable of reducing radio resource consumption and a related device thereof. The method comprises the following steps of: setting an active time slot window on communication time, wherein the communication time at least comprises a receiving time slot; and converting the receiving time slot in the active time slot window into a transmission time slot. The technical scheme can reduce the radio resource consumption.

Description

technical field [0001] The present invention relates to a transmission method for a bluetooth system and related devices, especially a transmission method and a related device for actively transmitting packets from a slave device in a bluetooth system. Background technique [0002] Bluetooth (Bluetooth) system is a wireless short-range communication system, with Piconet as the smallest network unit, using Time Division Duplexing technology to allow a master device (Master Device) and up to seven slave devices (Slave Device) communicate information to each other. The Bluetooth system divides a plurality of consecutive time slots (time slots) in the communication time of the physical layer channel, and labels the time slots according to the clock pulse of the master device, and even-numbered time slots are used as "Master-to-Slave" (Master-to-Slave) time slots, while odd time slots are used as "slave-to-master" time slots. In terms of transmission timing, the master and slav...
