and the first fallback action code indicates that when the UE is configured, at the first subcarrier spacing, with more than the maximum number of CCs, it will support the first capability only on ⌊ M × N cell , feature μ - N C ⁢ e ⁢ l ⁢ l μ M - 1 ⌋ ⁢ ⁢ CCs , wherein M is the number of TRPs, Ncell,featureμ is the first maximum number of CCs, and NCellμ is the number of CCs with which the UE is configured, at the first subcarrier spacing. ### Claim 11 (depends on 5) The method of claim 5, wherein: the first capability is out of order (OoO) reception; and the first fallback action code indicates that when the UE is configured, at the first subcarrier spacing, with more than the maximum number of CCs, it will support the first capability only on ⌊ M × N cell , feature μ - N C ⁢ e ⁢ l ⁢ l μ M - 1 ⌋ ⁢ ⁢ CCs , wherein M is the maximum possible number of overlapping or OoO PDSCHs with different priorities, Ncell,featureμ is the first maximum number of CCs, and NCellμ is the number of CCs with which the UE is configured, at the first subcarrier spacing. ### Claim 12 (depends on 5) The method of claim 5, wherein the first report further comprises: a second maximum number of CCs for which, at a second subcarrier spacing, the user equipment supports the first capability of the one or more capabilities, and a second fallback action code, the second fallback action code specifying the behavior of the UE when configured, at the second subcarrier spacing, with more than the second maximum number of CCs. ### Claim 13 (depends on 12) The method of claim 12, wherein the first report further comprises: a third maximum number of CCs for which, at the first subcarrier spacing, the user equipment supports a second capability of the one or more capabilities, and a third fallback action code, the third fallback action code specifying the behavior of the UE when configured, at the first subcarrier spacing, with more than the third maximum number of CCs. ### Claim 14 A method comprising: receiving, by a network, from a user equipment (UE), a first report, comprising a report of one or more capabilities selected from the group consisting of: reports of capabilities in support of multi-transmission and reception point (M-TRP) schemes, reports of capabilities in support of uRLLC service, and reports of capabilities in support of out of order (OoO) processing; and responsive to receiving the first report, implementing a response protocol suitable for a UE having the one or more capabilities. ### Claim 15 (depends on 14) The method of claim 14, wherein the first report further comprises an identification of a component carrier (CC), and the first report applies to the component carrier. ### Claim 16 (depends on 14) The method of claim 14, wherein the first report further comprises an identification of a band, and the first report apples to component carriers (CCs) in the band. ### Claim 17 (depends on 14) The method of claim 14, wherein the first report further comprises an identification of a combination of bands, and the first report apples to component carriers (CCs) in the combination of bands. ### Claim 18 (depends on 14) The method of claim 14, wherein the first report further comprises: a first maximum number of CCs for which, at a first subcarrier spacing, the user equipment supports a first capability of the one or more capabilities, and a first fallback action code, the first fallback action code specifying the behavior of the UE when configured, at the first subcarrier spacing, with more than the first maximum number of CCs. ### Claim 19 (depends on 18) The method of claim 18, wherein the first fallback action code indicates that when the UE is configured, at the first subcarrier spacing, with more than the first maximum number of CCs, it will not support the first capability. ### Claim 20 A user equipment comprising: a processing circuit, the processing circuit being configured to sending, to a network, a first report, comprising a one or more of capabilities selected from the group consisting of: reports of capabilities in support of multi-transmission and reception point (M-TRP) schemes, reports of capabilities in support of uRLLC service, and reports of capabilities in support of out of order (OoO) processing.
