Claim

1. A method for performing, by a user equipment (UE), random access in a wireless communication system, the method comprising:
receiving a first set of random access channel (RACH) resources for a short transmission time interval (TTI) and a second set of RACH resources for a normal TTI from an eNodeB (eNB); and performing random access towards the eNB by using the first set of RACH resources for the short TTI, wherein the first set of RACH resources is configured for a specific carrier, for a specific group of carriers, for a specific cell, for a specific cell group (CG), for a specific timing advance group (TAG), for a specific UE group, for a specific logical channel or for a specific logical channel group (LCG).', 'receiving a first set of random access channel (RACH) resources for a short transmission time interval (TTI) and a second set of RACH resources for a normal TTI from an eNodeB (eNB); and', 'performing random access towards the eNB by using the first set of RACH resources for the short TTI,', 'wherein the first set of RACH resources is configured for a specific carrier, for a specific group of carriers, for a specific cell, for a specific cell group (CG), for a specific timing advance group (TAG), for a specific UE group, for a specific logical channel or for a specific logical channel group (LCG).

2. The method of claim 1, wherein the random access is performed in the short TTI.

3. The method of claim 1, wherein the random access is performed at the specific carrier, at the specific group of carriers, at the specific cell, at the specific CG or at the specific TAG.

4. The method of claim 1, wherein the random access is performed to transmit a scheduling request due to data available for the specific logical channel or for the specific LCG.

5. The method of claim 1, wherein the eNB considers that the UE supports the short TTI.

6. The method of claim 1, further comprising receiving an indication indicating which cell, which CG, which radio bearer, which LCG, which carrier, or which group of carriers is configured for the short TTI from the eNB.

7. The method of claim 6, wherein the indication is received via a radio resource control (RRC) connection reconfiguration.

8. A method for performing, by a user equipment (UE), contention based uplink (UL) transmission in a wireless communication system, the method comprising:
receiving resources for contention based UL (CB-UL) transmission; and performing the CB-UL transmission by using the resources for the CB-UL transmission, wherein the resources for the CB-UL transmission is configured for a specific carrier, for a specific group of carriers, for a specific cell, for a specific cell group (CG), for a specific timing advance group (TAG), for a specific UE group, for a specific logical channel or for a specific logical channel group (LCG).', 'receiving resources for contention based UL (CB-UL) transmission; and', 'performing the CB-UL transmission by using the resources for the CB-UL transmission,', 'wherein the resources for the CB-UL transmission is configured for a specific carrier, for a specific group of carriers, for a specific cell, for a specific cell group (CG), for a specific timing advance group (TAG), for a specific UE group, for a specific logical channel or for a specific logical channel group (LCG).

9. The method of claim 8, wherein the CB-UL transmission is one of a contention based physical uplink shared channel (CB-PUSCH) transmission or a contention based scheduling request (CB-SR) transmission

10. The method of claim 9, wherein the CB-PUSCH transmission comprises transmission of a buffer status report (BSR)

11. The method of claim 9, wherein the CB-UL transmission is performed at the specific carrier, at the specific group of carriers, at the specific cell, at the specific CG or at the specific TAG

12. The method of claim 8, wherein the CB-UL transmission is performed for data available for the specific logical channel or for the specific LCG

13. The method of claim 8, wherein the eNB considers that the UE supports the CB-UL transmission

14. The method of claim 8, further comprising receiving an indication indicating which cell, which CG, which radio bearer, which LCG, which carrier, or which group of carriers is configured for the CB-UL transmission from the eNB

15. The method of claim 14, wherein the indication is received via a radio resource control (RRC) connection reconfiguration.']
