Claim(s) 6 and 15 is/are rejected under 35 U.S.C. 103 as being unpatentable over Higuchi, US 2010/0304665 A1 (Higuchi here in after), in view of Wentink, US 2005/0094588 A1 (Wentink hereinafter), in view of Kobayashi et al., US 2006/0293061 A1 (Kobayashi hereinafter), as applied to the claims above and further in view of Mehta et al., US 2007/0165581 A1 (Mehta hereinafter).
Here is how the references teach the claims.
Regarding claims 6 and 15, Higuchi, Wentink Kobayashi disclose the communication system according to claim 5 and the communication control method according to claim 14. Higuchi, Wentink and Kobayashi do not explicitly disclose the following features.
Regarding claim 6, wherein the communication control apparatus selects, from among a plurality of the first relay stations, a first relay station, to which a second gain that is larger than a first gain requested of relay stations for relaying of the terminal station has been requested regarding relaying of a terminal station other than the terminal station and the second gain value is closest to the first gain value, as a relay station to be used for the relaying.
Regarding claim 15, wherein the communication control apparatus selects, from among a plurality of the first relay stations, a first relay station, to which a second gain that is larger than a first gain requested of relay stations for relaying of the terminal station has been requested regarding relaying of a terminal station other than the terminal station and the second gain value is closest to the first gain value, as a relay station to be used for the relaying.
In the same field of endeavor (e.g., communication system) Mehta discloses a method related to communicating information in a cooperative relay network of wireless nodes that comprises the following features.
Regarding claim 6, wherein the communication control apparatus selects, from among a plurality of the first relay stations, a first relay station (Mehta, paragraph [0012], The embodiments of the invention provide a method for selecting a subset of relay nodes and for satisfying an outage constraint in a cooperative relay network. The selected relay nodes cooperate to relay data packets from a source node to a destination node in parallel), to which a second gain that is larger than a first gain requested of relay stations for relaying of the terminal station has been requested regarding relaying of a terminal station other than the terminal station and the second gain value is closest to the first gain value, as a relay station to be used for the relaying (Mehta, paragraph [0064], The destination can declare outage when the sum of the relay gains falls below a threshold. Similarly, an alternate relay selection rule selects enough relays so that a sum of relay gains exceeds the threshold. Also paragraph [0153], If M >M*, the destination selects K*(M) relays and does not declares outage 350, unless the condition 340 M=1 is met, in which case, the destination allows the relay to transmit 360 only if its relay gain is above a threshold).
Regarding claim 15, wherein the communication control apparatus selects, from among a plurality of the first relay stations, a first relay station (Mehta, paragraph [0012], The embodiments of the invention provide a method for selecting a subset of relay nodes and for satisfying an outage constraint in a cooperative relay network. The selected relay nodes cooperate to relay data packets from a source node to a destination node in parallel), to which a second gain that is larger than a first gain requested of relay stations for relaying of the terminal station has been requested regarding relaying of a terminal station other than the terminal station and the second gain value is closest to the first gain value, as a relay station to be used for the relaying (Mehta, paragraph [0064], The destination can declare outage when the sum of the relay gains falls below a threshold.

Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the system of Higuchi, Wentink and Kobayasi by using the features, as taught by Mehta, in order to consider the cost of acquiring channel state information (CSI) in relay selection so that the selection process can be optimized, and total power consumption in the network can be minimized (see Mehta, abstract and paragraph [0011]).
Claim(s) 9 and 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Higuchi, US 2010/0304665 A1 (Higuchi here in after), in view of Wentink, US 2005/0094588 A1 (Wentink hereinafter), as applied to the claims above and further in view of Mehta et al., US 2007/0165581 A1 (Mehta hereinafter).
Here is how the references teach the claims.
Regarding claims 9 and 18, Higuchi and Wentink disclose the communication system according to claim 1 and the communication control method according to claim 10. Higuchi and Wentink do not explicitly disclose the following features.
Regarding claim 9, wherein the communication control apparatus transmits to a selected relay station an instruction of the relaying and an instruction to set a gain to be applied for the relaying.
Regarding claim 18, wherein the communication control apparatus transmits to a selected relay station an instruction of the relaying and an instruction to set a gain to be applied for the relaying.
