The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 1-4, 10-14 and 18-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Pang (CN116017385A) in view of Bardini (U.S. PG-PUB NO. 2003/0169687) and further in view of Choi (U.S. PATENT NO. 6963540).
-Regarding claim 1, Pang discloses a BLE broadcast communication method applied to a master device configured to perform a broadcast communication with one or more slave devices in a plurality of consecutive isochronous intervals based on an isochronous channel, the isochronous interval provided with a data broadcast time slot (Bluetooth LE Audio defines a time-dependent data transmission channel and transmission strategy. LE Audio broadcast synchronous channel (BIG/BIS) is based on the periodic advertising (Periodic Advertising) technology of low-power Bluetooth, and realizes audio transmission on the broadcast isochronous channel (BIG/BIS), paragraph 29-31), the method comprising: broadcasting the BIS packet in the data broadcast time slot (broadcast synchronous channel, based on Bluetooth LE Audio broadcast synchronous channel (BIG/BIS) characteristics by Bluetooth 5.x, paragraph 29-31).
Pang is silent to teaching that a shared reverse control time slot being a time slot that is occupiable by any one of the slave devices when transmitting a reverse control packet;
configuring a reverse communication enable instruction in a BIS packet to be broadcast, the reverse communication enable instruction being used to indicate whether a reverse communication is permitted in the current isochronous interval; and receiving based on the isochronous channel in the shared reverse control time slot of the current isochronous interval to obtain the reverse control packet transmitted by one of the slave devices when the reverse communication enable instruction indicates that the reverse communication is permitted in the current isochronous interval under the condition that each slave device is not required to be allocated with an exclusive time slot for the reverse communication. However, the claimed limitation is well known in the art as evidenced by Bardini and Choi.
In the same field of endeavor, Bardini teaches a reverse control time slot being a time slot that is occupiable by any one of the slave devices when transmitting a reverse control packet (receiving device creates and outputs the isochronous back channel packet with control instructions for the transmitting device, paragraph 68); configuring a reverse communication enable instruction in a packet to be broadcast, the reverse communication enable instruction being used to indicate whether a reverse communication is permitted in the current isochronous interval (The enable field is set to indicate whether or not the plug is configured for non real-time A/V content transmission/reception, paragraph 57); and receiving based on the isochronous channel in the reverse control time slot of the current isochronous interval to obtain the reverse control packet transmitted by one of the slave devices when the reverse communication enable instruction indicates that the reverse communication is permitted in the current isochronous interval under the condition (The control field of the isochronous back channel packet is read to determine if the transmitting device is to retransmit, hold off transmission, or resume transmission, paragraph 76).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to combine the teaching of Pang with the teaching of Bardini in order to avoid an overflow condition.

-Regarding claim 2, the combination further discloses said configuring a reverse communication enable instruction in a BIS packet to be broadcast comprises: configuring a control sub-event transmission flag in the BIS packet to be broadcast, the control sub-event transmission flag being used to indicate whether the master device transmits a control packet in the current isochronous interval (Bardini, Other values can be defined for the control field to indicate various other control instructions, paragraph 71).
-Regarding claim 3, the combination further discloses the isochronous interval is further provided with a control time slot for the master device to broadcast the control packet; the method further comprises: entering the control time slot after the data broadcast time slot of the current isochronous interval and broadcasting the control packet based on the isochronous channel in the control time slot when the control sub-event transmission flag indicates that the master device transmits the control packet in the current isochronous interval (Bardini, an isochronous data packet is transmitted only during the isochronous period, paragraph 11; Choi, The access slot is a reference slot for transmitting and receiving the AP and AP_AICH in the W-CDMA system, and 15 access slots are provided for a 20 ms frame as shown by reference numeral 411, col. 12).

-Regarding claim 10, Pang discloses a BLE broadcast communication method applied to a slave device configured to perform a broadcast communication with a master device in a plurality of consecutive isochronous intervals based on an isochronous channel, the isochronous interval provided with a data broadcast time slot (Bluetooth LE Audio defines a time-dependent data transmission channel and transmission strategy. LE Audio broadcast synchronous channel (BIG/BIS) is based on the periodic advertising (Periodic Advertising) technology of low-power Bluetooth, and realizes audio transmission on the broadcast isochronous channel (BIG/BIS), paragraph 29-31), the method comprising: receiving a BIS packet broadcast by the master device in the data broadcast time slot (broadcast synchronous channel, based on Bluetooth LE Audio broadcast synchronous channel (BIG/BIS) characteristics by Bluetooth 5.x, paragraph 29-31).

However, the claimed limitation is well known in the art as evidenced by Bardini and Choi.
In the same field of endeavor, Bardini teaches a reverse control time slot being a time slot that is occupiable by any one of the slave devices when transmitting a reverse control packet (receiving device creates and outputs the isochronous back channel packet with control instructions for the transmitting device, paragraph 68) and obtaining a reverse communication enable instruction carried in the packet, the reverse communication enable instruction being used to indicate whether a reverse communication is permitted in the current isochronous interval (The enable field is set to indicate whether or not the plug is configured for non real-time A/V content transmission/reception, paragraph 57); and transmitting a reverse control packet based on the isochronous channel in the reverse control time slot when the reverse communication enable instruction indicates that the reverse communication is permitted in the current isochronous interval and the slave device determines that the reverse communication is required under the condition (The control field of the isochronous back channel packet is read to determine if the transmitting device is to retransmit, hold off transmission, or resume transmission, paragraph 76).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to combine the teaching of Pang with the teaching of Bardini in order to provide avoid an overflow condition.
The combination is silent to teaching that shared and that this slave device is not required to be allocated with an exclusive time slot for the reverse communication. However, the claimed limitation is well known in the art as evidenced by Choi.
