Definitions
- the present invention relates to wireless communication, and more particularly to a method for opening a channel used in a wireless communication apparatus and a wireless communication system.
- centralized network In wireless communication, there are two main types of networks: “centralized network” and “distributed network”.
- channel time is controlled by a specific control device generally called “master device”.
- master device a specific control device
- slave devices Other devices that rely on the master device for network control other than the master device are commonly referred to as “slave devices”.
- master device a specific control device
- slave devices There are many forms of this centralized network.
- centralized networks there is only one slave device. This type of network is called a “point-to-point network”, “master / slave pair”, or “master / slave network”. In another form of centralized network, there are two or more slave devices that couple to the master device.
- the “polling frame” is sometimes referred to as a “beacon frame”, but here it is referred to as a “polling frame”.
- a polling frame is a special frame transmitted by the master device and is transmitted mainly for the following purposes. -Allow other devices to discover the master device-Provide other devices with a means to synchronize time information with the master device-Provide a means to notify the master devices about network-related information
- the first problem of the second master device (503) is to notify the detected first master device (501) of the presence of the own device. Since the communication procedure between the master-to-master devices in the centralized network is not generally defined, it is difficult for the second master device (503) to communicate with the first master device (501).
- the first master device (501) is first coupled to the second master device (503).
- the first problem can be solved.
- the second master device (703) has the same problem as that shown in FIG. 7
- FIG. 12 shows the frame format of the polling response frame (900a).
- the polling response frame (900a) includes at least a physical layer (PHY) header (901a), a medium access control (MAC) header (902a), and other polling response frame information (904a).
- PHY physical layer
- MAC medium access control
- a “channel release request command” is defined in order for the second master device to request the first master device or slave device in the network of the first master device to release the current channel.
- FIG. 18 shows an example of a frame format (1400) of a channel release request command composed of the following.
- the frame format (1400) includes information such as a physical layer (PHY) header (1401), a medium access control (MAC) header (1402), network identification information of the network of the target device, and a channel if necessary. It consists of a channel release command payload (1403) including the reason for release.
- PHY physical layer
- MAC medium access control
- 1403 a channel release command payload
- an existing frame format for polling or “beacon”
- an existing command frame can be used by embedding information indicating the intention of “channel release request”.
- the timing is calculated based on the timing information in the polling frame timing IE of the master device received last, and the timing information is not based on the time when the last polling frame is received but on the time when the slave device transmits the frame. It shall be adjusted so that it may become relatively.
- the slave device embeds the synchronization information in the frame format (as shown in FIGS. 15 and 16) after the timing IE is determined and before the frame transmission.
- the device When the device receives a certain level of interference after power-on, it starts the channel release request procedure (1801).
- the channel release request procedure After the start of the channel release request procedure (1801), in order to detect the presence / absence of an existing device, it is assumed that the channel is scanned for frame transmission (1802). If there is no received frame transmission (1803: No), the channel release request procedure ends (1812).
- the apparatus checks the type of the transmission source apparatus of the received frame (1804). If the transmission frame transmission source device is the master device, the frame type of the reception frame is confirmed (1805).
- the apparatus If the frame type is not a polling frame, the apparatus returns to the channel rescanning operation (1802). On the other hand, if the frame type is a polling frame, the apparatus transmits a channel release request command frame with the highest contention priority in the CEP (1806).
- the highest contention priority depends on the implementation. For example, if the contention mechanism used in CEP is CSMA / CA with a random backoff selected from an integer value frame from “1” to “7”, the “highest contention priority” is It means the application of a random back-off value “1”, which is the minimum back-off latency.
- the channel release request command frame is transmitted as a broadcast frame. However, in some cases, the receiving side apparatus can transmit the frame as a unicast frame that requests an acknowledgment frame to be returned as necessary.
- the apparatus goes to the channel release request command retransmission operation (1806) in the CEP.
- the process returns to the channel time scanning operation for frame transmission (1802).
- FIG. 21 shows the channel opening request command frame (1504) in the CEP (1502) with the highest priority when the polling frame (1501) transmission by the master device is received during the scan operation process (1802). The network period at the time of transmitting is illustrated.
- the device After the channel scanning operation, if the above-mentioned frame is received from the slave device instead of the master device, the device acquires timing synchronization information from the timing IE field of the received frame (1809). This is possible because all frames transmitted by the slave device embed the timing IE. After acquiring timing synchronization information from the timing IE field of the received frame (1809), the device can determine the timing of the network period of the transmission source slave device, so it can be determined whether or not it is currently a CEP (1810).
- the device can determine that it is currently in the CEP (1703), it can begin broadcasting the channel release request command (1710) during the current CEP (1703).
- FIG. 24 shows a flowchart of the response procedure of the master device for the received channel release request command frame.
- the master device After receiving the channel release request command frame during CEP, the master device enters the start of channel release response procedure (2001), and whether the received channel release command request frame is addressed to the current network belonging to its own device. Is determined (2002).
