Claim Rejections - 35 USC § 103
6. 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.
Claim(s) 3-7, 10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Uchiyama and further in view of Cheng et al. (US 20240007922 A1) hereinafter Cheng

Uchiyama teaches wherein the communicating includes: communicating between the first mobile device and the host device using the main channel; ; ([0065] Fig. 1, terminal apparatus 300 form a link to perform uplink and downlink wireless communication with the base station apparatus 100 e.g., direct link )
Uchiyama does not teach determining a likelihood of disconnection to the main channel; and communicating with the host device using the sub channel, when the likelihood of disconnection has a value greater than or equal to a reference value.
Cheng teaches determining a likelihood of disconnection to the main channel;([0051] a user equipment (UE) may be outside the coverage area of a base station or may otherwise experience a poor channel quality (e.g., below a channel quality threshold) associated with direct communications with base station e.g., determine likely to fail connection))
and communicating with the host device using the sub channel,([0051] the UE may communicate with the base station via a relay UE e.g., use sub-channel)
when the likelihood of disconnection has a value greater than or equal to a reference value. ([0097] Fig. 1, If the channel metric for the current relay connection fails to satisfy the threshold value (e.g., a sidelink RSRP for the serving relay UE 115-e is below a threshold RSRP value), a channel metric for the current relay connection failing to satisfy a first threshold value and a channel metric for a candidate relay satisfying a second threshold value (e.g., a candidate relay sidelink RSRP is greater than or equal to the second threshold value).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Cheng with the teaching of Uchiyama because Cheng teaches that switching the relay paths may allow the device to transmit with a higher code rate, perform fewer retransmissions, thereby channel overhead.(Cheng [0126])
As to claim 4. Uchiyama does not teach , further comprising: setting a connection boosting mode supporting the sub channel.

The UE 115 may discover a relay UE and may use the relay UE as a UE-to-network relay. The UE 115 may transmit messages to the selected relay UE, and the relay UE 115 may relay the messages to a base station 105/connection enhancement mode).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Cheng with the teaching of Uchiyama because Cheng teaches that switching the relay paths may allow the device to transmit with a higher code rate, perform fewer retransmissions, thereby channel overhead.(Cheng [0126])

The UE 115 may discover a relay UE and may use the relay UE as a UE-to-network relay. The UE 115 may transmit messages to the selected relay UE, and the relay UE 115 may relay the messages to a base station 105/connection enhancement mode).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Cheng with the teaching of Uchiyama because Cheng teaches that switching the relay paths may allow the device to transmit with a higher code rate, perform fewer retransmissions, thereby channel overhead.(Cheng [0126])
As to claim 6. The combination of Uchiyama and Cheng specifically Uchiyama teaches determining whether a signal strength level of a signal transmitted from the main channel has a value less than a reference value. ([0187] Fig. 1, terminal apparatus may determine its own position on the basis of, for example, RSRP (Reference Signal Received Power) from the base station apparatus 100; may determine to be positioned at a cell edge in a case where the RSRP is smaller than the threshold value).
As to claim 7. The combination of Uchiyama and Cheng specifically Cheng teaches, wherein the communicating includes communicating with the host device using the sub channel, when the signal strength level of the signal has the value less than the reference value. ([0084] Fig. 1, UE 115 may be a remote UE or the UE 115 may experience relatively poor channel conditions (e.g., below one or more channel quality metrics) between the UE 115 and a base station 105. The UE 115 may discover a relay UE and may use the relay UE as a UE-to-network relay. The UE 115 may transmit messages to the selected relay UE, and the relay UE 115 may relay the messages to a base station 105 e.g., when s/connection enhancement mode).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Cheng with the teaching of Uchiyama because Cheng teaches that switching the relay paths may allow the device to transmit with a higher code rate, perform fewer retransmissions, thereby channel overhead.(Cheng [0126])
As to claim 10. The combination of Uchiyama and Cheng specifically Uchiyama teaches wherein communication is performed using one of the main channel ([0065] Fig. 1, terminal apparatus 300 form a link to perform uplink and downlink wireless communication with the base station apparatus 100 e.g., direct link )and the sub channel, ;([0066] Fig. 1, UE communicate with base station 100 via relay UE 200, by establishing sidelink to Relay UE 200 and a backhaul link to base station 100 )

([0084] Fig. 1, UE 115 may be a remote UE or the UE 115 may experience relatively poor channel conditions (e.g., below one or more channel quality metrics) between the UE 115 and a base station 105. The UE 115 may discover a relay UE and may use the relay UE as a UE-to-network relay. The UE 115 may transmit messages to the selected relay UE, and the relay UE 115 may relay the messages to a base station 105/connection enhancement mode).
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filling date of the claimed invention to combine teaching of Cheng with the teaching of Uchiyama because Cheng teaches that switching the relay paths may allow the device to transmit with a higher code rate, perform fewer retransmissions, thereby channel overhead.(Cheng [0126])
