Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-4, 6-7, 11, 13, 15-17 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Nam et al. (US 2021/0037503 A1)(“Nam”).

Nam [0082]; In another example, a joint QCL indication may be transmitted to the destination UE (UE1). Specifically, transmission configuration indication (TCI) state/spatial relation can be configured as a combination of one or more QCL source reference signals on different links, such as access link reference signals (AL-RS(s)) and sidelink reference signals (SL-RS(s)). The base station (e.g., BE 802), along with the access link and sidelink grant, may send joint access link-sidelink QCL information to destination UE (e.g., UE1 804). For example, the joint QCL information may indicate the transmission and/or reception beams that the UE may use for access link (first radio link) and sidelink transmission and/or reception (second radio link).

The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG including four consecutive REs in an OFDM symbol. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 (104b= relay) to determine subframe/symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the locations of the aforementioned DM-RS. The physical broadcast channel (PBCH), which carries a master information block (MIB), may be logically grouped with the PSS and SSS to form a synchronization signal (SS)/PBCH block. The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs), and paging messages (the relay device configured to utilize the physical layer).

Chiu [0016]; The base station receives channel state information (CSI) reported by the source UE, the destination UE, and the relay UE. The base station estimates link qualities of all D2D communication pairs according to the CSI, and determines a suitable D2D communication mode from the source UE to the destination UE according to the link qualities, and transmits a resource grant to the source UE to instruct the source UE to transmit data packets to the destination UE in the suitable D2D communication mode.
In view of Chiu Nam is modified such that the device is receiving a CSI report from the at least one second device, the CSI report including the CSI corresponding to the at least one second radio link;
Nam and Chiu are analogous art to the claimed invention because they are in the same field of endeavor, sidelink transmission of data.
It would be obvious before the effective filing date of claimed invention, to a person ordinary skill in the
art to modify Nam in the manner described above to receive the CSI report via the sidelink transmission to determine the quality of sidelink channel to adjust the timing and frequency of the channel.
Claim 27 is rejected under 35 U.S.C. 103 as being unpatentable over Nam in view of Zhou in further view of Fan et al. (US 20150271804 A1)(“Fan”).
Regarding claim 27, The method of claim 20, wherein the receiving of the indication comprises
over the at least one first radio link,
Nam [0038]; The destination UE 104a may have a first access link 120a directly with the base station 102a (one first radio link),
Nam does not teach receiving, an acknowledgment message during a first timeframe of a first predetermined feedback timeline;
Fan teaches receiving, an acknowledgment message during a first timeframe of a first predetermined feedback timeline;
Fan [0056]; In this embodiment, the sending unit 107 sends the code of the HARQ-ACK information of the feedback information and the code of the CQI information of the feedback information to the second base station 104 through the HS-DPCCH channel, and when the second base station 104 receives the feedback information, the second base station 104 needs to separately process the two pieces of HARQ-ACK information carried on the first time slot, in order to avoid that the second base station 104 obtains no HARQ-ACK information within an appointed duration due to time delay.
In view of Fan, Nam is modified such an acknowledgment message is received during a first timeframe of a first predetermined feedback timeline;
Nam and Fan are analogous art to the claimed invention because they are in the same field of endeavor, transmission of data.
It would be obvious before the effective filing date of claimed invention, to a person ordinary skill in the
art to modify Nam in the manner described above to receive the acknowledgment message in the first and second time frame to improve the flexibility of data transmission.
