Allowable Subject Matter
5. Claims 2-5, 8-11, 14-17 and 20 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.
Conclusion
6. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: US 2023/0353315 discloses [0128] In some aspects, the expansion of the number of ports may be per CDM group to accommodate legacy UE multiplexing. For example, if the legacy UE is assigned one or more ports for a certain CDM group, then it may not be possible to assign other extended ports to that CDM group.
