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.
Claims 6-9, 14-15, 21-24, and 29-30 are rejected under 35 U.S.C. 103 as being unpatentable over Lim et al. in view of Jang et al. (U.S. Publication US 2023/0081649 A1).
With respect to claims 6 and 21, Lim et al. does not specifically disclose wherein the one or more processors are further configured to cause the first wireless communication device to: obtain M-RU capability information associated with the second wireless communication device, wherein transmitting the indication that specifies activation of the M-RU MU communications is based at least in part on the M-RU capability information.
With respect to claims 7 and 22, Lim et al. does not specifically disclose wherein the M-RU capability information indicates the second wireless communication device supports the M-RU MU communications.
With respect to claims 8 and 23, Lim et al. does not specifically disclose wherein the one or more processors are further configured to cause the first wireless communication device to: select a number of RUs associated with the second MU transmission to allocate to the second wireless communication device based at least in part on the M-RU capability information.
With respect to claims 9 and 24, Lim et al. does not specifically disclose wherein the M-RU capability information indicates device capabilities associated with at least one of: duplicate transmission support, a maximum number of decodable physical layer service data units (PSDUs), or a performance condition.
With further respect to claims 6-9 and 21-24, Jang et al., in the field of communications, discloses an AP receiving an indication of a MRU capability of a STA indicating whether or not the STA has the MRU capability, such that the AP allocates multiple RUs to a STA having the MRU capability and does not allocate multiple RUs to a STA not having the MRU capability thereby selecting a number of RUs allocated to the STA based on the MRU capability, wherein the MRU capability further indicates a transmission capability when a RU of the multiple RUs is in a busy state, which is a performance condition (See paragraphs 355-361 and Figure 36 of Jang et al.). Using an indicated MRU capability of a STA to determine RU allocation of the STA has the advantage of only allowing allocation of MRUs to stations capability of communicating via MRUs. Thus, it would have been obvious for one of ordinary skill in the art at the time of effective filing, when presented with the work of Jang et al., to combine using an indicated MRU capability of a STA to determine RU allocation of the STA, as suggested by Jang et al., within the system and method of Lim et al., with the motivation being to only allow allocation of MRUs to stations capability of communicating via MRUs.
With respect to claims 14 and 29, Lim et al. does not specifically disclose wherein the one or more processors are further configured to cause the second wireless communication device to: transmit M-RU capability information that indicates support for the M-RU MU communications.
With respect to claims 15 and 30, Lim et al. does not specifically disclose wherein the M-RU capability information indicates device capabilities associated with at least one of: duplicate transmission support, a maximum number of decodable physical layer service data units (PSDUs), or a performance condition.
With further respect to claims 14-15 and 29-30, Jang et al., in the field of communications, discloses a STA transmitting an indication of a MRU capability of the STA to the AP indicating whether or not the STA has the MRU capability, such that the AP allocates multiple RUs to a STA having the MRU capability and does not allocate multiple RUs to a STA not having the MRU capability, wherein the MRU capability further indicates a transmission capability when a RU of the multiple RUs is in a busy state, which is a performance condition (See paragraphs 355-361 and Figure 36 of Jang et al.). Using an indicated MRU capability of a STA to determine RU allocation of the STA has the advantage of only allowing allocation of MRUs to stations capability of communicating via MRUs. Thus, it would have been obvious for one of ordinary skill in the art at the time of effective filing, when presented with the work of Jang et al., to combine using an indicated MRU capability of a STA to determine RU allocation of the STA, as suggested by Jang et al., within the system and method of Lim et al., with the motivation being to only allow allocation of MRUs to stations capability of communicating via MRUs.
Allowable Subject Matter
Claims 4, 12, 19, and 27 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: Claims 4, 12, 19, and 27 would be allowable since the prior art of record fails to disclose or render obvious enabling multi-link operations with based at least in part on the deactivation of the M-RU MU communication, as claimed. The closest prior art of record is Lin et al. (U.S. Publication US 2026/0025867 A1), which discloses multiple resource unit allocation used in a system wherein an Enhanced Multi-Link Multi-Radio mode may be enabled or disabled in a set of EMLMR links (See paragraph 2 of Lin et al.); however, Lin et al. does not disclose or render obvious the claimed enabling multi-link operations with based at least in part on the deactivation of the M-RU MU communication.
