Abstract
A base wireless device includes plural transmission buffers storing plural signals having transmission destinations that are different from each other, a transmission processing unit transmitting the signals to plural remote wireless devices respectively, by transmitting the signals stored in the plural transmission buffers in a predetermined order, regardless of whether or not each transmission has been made successfully, and a storage control unit, wherein when a transmission of a signal stored in one of the transmission buffers has been made successfully, the storage control unit overwrites the one transmission buffer from which the transmission has been made successfully, with another signal to be transmitted to a transmission destination that is different from a transmission destination of a signal stored in a transmission buffer other than the one transmission buffer from which the transmission has been made successfully, among the plural transmission buffers.
Core Innovation
A base wireless device carries out transmission and reception of signals to and from a plurality of remote wireless devices. The device stores a plurality of signals in a plurality of transmission buffers configured for transmission destinations different from each other, where each transmission buffer is nonexclusive for each transmission destination and is capable of storing, one after another, different signals to be transmitted to different transmission destinations. The plurality of transmission buffers are physically distinct from each other.
The device transmits the signals stored in the plurality of transmission buffers to the plurality of remote wireless devices respectively. The transmission processing unit transmits the signals stored in the transmission buffers in a predetermined order regardless of whether or not each transmission has been made successfully. This transmission operation continues without being dependent on per-signal success.
When a transmission of a signal stored in one transmission buffer has been made successfully, a storage control unit overwrites the one transmission buffer from which the successful transmission has been made. The overwriting stores another signal to be transmitted to a transmission destination different from the transmission destination of a signal stored in a transmission buffer other than the one buffer. The overwritten buffer therefore supplies the next signal among the plurality of physically distinct nonexclusive transmission buffers after a success.
Claims Coverage
The independent claims cover a base wireless device and a wireless communication method that use physically distinct, nonexclusive transmission buffers to buffer multiple destination-specific signals, transmit them in a predetermined order regardless of transmission success, and overwrite a successfully-used buffer with a different-destination signal. Across the independent claims, the core inventive structure comprises 3 main inventive feature sets.
Physically distinct nonexclusive transmission buffers for different destinations
A plurality of transmission buffers configured to store a plurality of signals to be transmitted to the plurality of remote wireless devices, the plurality of signals having transmission destinations that are different from each other, wherein each of the plurality of transmission buffers is nonexclusive for each of the transmission destinations and is capable of storing, one after another, different signals to be transmitted to different transmission destinations, and wherein the plurality of transmission buffers are physically distinct from each other.
Predetermined-order transmission regardless of transmission success
A transmission processing unit configured to transmit the signals to the plurality of remote wireless devices respectively, by transmitting the signals stored in the plurality of transmission buffers in a predetermined order, regardless of whether or not each transmission has been made successfully.
Overwrite successful buffer with a different-destination signal
A storage control unit, wherein when a transmission of a signal stored in one of the transmission buffers has been made successfully, the storage control unit is configured to overwrite the one transmission buffer from which the transmission has been made successfully, with another signal to be transmitted to a transmission destination that is different from a transmission destination of a signal stored in a transmission buffer other than the one transmission buffer from which the transmission has been made successfully, among the plurality of transmission buffers.
The independent claims collectively require physically distinct, nonexclusive transmission buffers; predetermined-order transmission regardless of whether each transmission is successful; and overwriting only the transmission buffer corresponding to a successful transmission with another signal whose transmission destination differs from the destinations associated with other buffers.
Stated Advantages
Allows overwriting after a successful transmission so that additional signals can be sent using the buffer that succeeded.
Ensures transmissions are carried out in a predetermined order regardless of whether each transmission has been made successfully.
Documented Applications
Rapid industrial wireless communication in an industrial equipment context using a base wireless device communicating with remote wireless devices.
