modifying, by the relay device, a subset of the barring parameters associated with an access class barring type; and forwarding, by the relay device, the modified subset of the barring parameters to a remote device. ### Claim 2 (depends on 1) The method of claim 1, wherein the access class barring type is a non-service related type. ### Claim 3 (depends on 2) The method of claim 2, wherein the non-service related type comprises at least one of access class barring or enhanced access class barring. ### Claim 4 (depends on 1) The method of claim 1, wherein the barring parameters are included in system information blocks. ### Claim 5 (depends on 4) The method of claim 4, wherein at least a portion of the subset of the barring parameters are included in at least one of a system information block type 2 (SIB2) or a system information block type 14 (SIB14). ### Claim 6 (depends on 5) The method of claim 5, wherein the subset of the barring parameters is included in the SIB2, and wherein modifying the subset of the barring parameters comprises setting an indication for at least one access class barring type to a false value. ### Claim 7 (depends on 5) The method of claim 5, wherein the subset of the barring parameters is included in the SIB2, and wherein modifying the subset of the barring parameters comprises omitting a field including an indication for at least one connection type. ### Claim 8 (depends on 5) The method of claim 5, wherein the subset of the barring parameters is included in the SIB14, and wherein modifying the subset of the barring parameters comprises setting a barring bitmap to indicate that the access class barring type is not barred. ### Claim 9 (depends on 8) The method of claim 8, wherein modifying the subset of the barring parameters further comprises omitting a per public land mobile network (PLMN) list of barring information. ### Claim 10 A relay device adapted to perform access barring, the relay device comprising: a non-transitory memory storage comprising instructions; and one or more processors in communication with the memory storage, wherein the one or more processors execute the instructions to: receive barring parameters, modify a subset of the barring parameters associated with an access class barring type, and forward the modified subset of the barring parameters to a remote device. ### Claim 11 (depends on 10) The relay device of claim 10, wherein the access class barring type is a non-service related type. ### Claim 12 The relay device of claim ii, wherein the non-service related type comprises at least one of access class barring or enhanced access class barring. ### Claim 13 (depends on 10) The relay device of claim 10, wherein the barring parameters are included in system information blocks. ### Claim 14 (depends on 13) The relay device of claim 13, wherein at least a portion of the subset of the barring parameters are included in at least one of a system information block type 2 (SIB2) or a system information block type 14 (SIB14). ### Claim 15 (depends on 14) The relay device of claim 14, wherein the subset of the barring parameters is included in the SIB2, and wherein the one or more processors executing the instructions to modify the subset of the barring parameters comprises the one or more processors executing the instructions to set an indication for at least one access class barring type to a false value. ### Claim 16 (depends on 14) The relay device of claim 14, wherein the subset of the barring parameters is included in the SIB2, and wherein the one or more processors executing the instructions to modify the subset of the barring parameters comprises the one or more processors executing the instructions to omit a field including an indication for at least one connection type. ### Claim 17 (depends on 14) The relay device of claim 14, wherein the subset of the barring parameters is included in the SIB14, and wherein the one or more processors executing the instructions to modify the subset of the barring parameters comprises the one or more processors executing the instructions to set a barring bitmap to indicate that the access class barring type is not barred. ### Claim 18 (depends on 17) The relay device of claim 17, wherein the one or more processors executing the instructions to modify the subset of the barring parameters comprises the one or more processors executing the instructions to omit a per public land mobile network (PLMN) list of barring information. ### Claim 19 A method for performing access barring, the method comprising: receiving, by a relay device, barring parameters in system information blocks; modifying, by the relay device, a subset of the barring parameters associated with a non-service related access class barring type; and forwarding, by the relay device, the modified subset of the barring parameters to a remote device. ### Claim 20 (depends on 19) The method of claim 19, wherein the non-service related type comprises at least one of access class barring or enhanced access class barring. ### Claim 21 (depends on 19) The method of claim 19, wherein at least a portion of the subset of the barring parameters are included in at least one of a system information block type 2 (SIB2) or a system information block type 14 (SIB14).
