A method for establishing Random Access between a user agent (UA) and an access device, comprising:

• receiving, by the access device, a IRA message one from the UA, the RA message one indicating a special preamble, wherein the special preamble indicates a request for resource allocation with transmission time interval bundling in a RA message three, wherein the special preamble is selected from a special preamble group signaled by the access device;
• sending, by the access device, a RA message two to the UA, the RA message two providing a resource allocation or uplink grant of a radio resource in response to the RA message one;
• and receiving, by the access device, the RA message three sent by the UA using transmission time interval bundling provided in the RA message two.

A user agent (UA), comprising:

• a component configured such that the UA sends a RA message one indicating a special preamble to an access device and receives a RA message two from the access device, the RA message two providing a resource allocation or uplink grant of a radio resource in response to the RA message one, the component further configured such that the UA sends a RA message three to the access device using transmission time interval bundling provided in the RA message two, wherein the special preamble indicates a request for resource allocation for with transmission time interval bundling in the RA message three, and the special preamble is selected from a special preamble group signaled by the access device.

An access device, comprising:

• a component configured such that the access device signals a special preamble group to the UA indicating special preambles to be used by the UA for requesting resource allocation with transmission time interval bundling, receives a RA message one from a user agent (UA) and sends a RA message two to the UA, the RA message two providing a resource allocation or uplink grant of a radio resource in response to the RA message one, the component further configured such that the access device receives a RA message three sent by the UA using transmission time interval bundling provided in the RA message two, wherein the RA message one indicates a special preamble, wherein the special preamble is selected from the special preamble group signaled by the access device and indicates a request for resource allocation with transmission time interval bundling in the RA message three.
