Abstract

A method of allocating resources and signatures of a random access resource (RACH) ( 200 ) that includes dedicated ( 202 ) and non-dedicated ( 204 ) resources or sub-resources is disclosed. The network device determines if the dedicated resource is available for allocation. If the dedicated resource is available, the network device allocates the dedicated resource. If the dedicated resource is blocked, the network device allocates one of the non-dedicated resources. A message can be sent that indicates that allocated non-dedicated resource is being allocated as a dedicated resource.

Claims (38)

1. A method comprising:

determining if a dedicated resource of a random access channel used in communications between network equipment and a first user equipment is available for allocation;

allocating the dedicated resource for the first user equipment when the dedicated resource is available;

allocating a non-dedicated resource of the random access channel used in the communications between network equipment and the first user equipment when the dedicated resource is blocked, and

sending a message indicating that the allocated non-dedicated resource is allocated as a dedicated resource when the allocated non-dedicated resources is requested as a non-dedicated resource by a second user equipment.

2. The method of claim 1 further comprising sending a message indicating that the allocated non-dedicated resource is allocated as a dedicated resource.

3. The method of claim 1 further comprising determining if activity is associated with the non-dedicated resource allocated as a dedicated resource.

4. The method of claim 3 further comprising sending a message when it is determined that activity is associated with the non-dedicated resource allocated as a dedicated resource.

5. The method of claim 4 further comprising sending an identifier when it is determined that activity is associated with the non-dedicated channel allocated as a dedicated channel.

6. The method of claim 1 further comprising allocating another non-dedicated resource when it is determined that the non-dedicated resource is allocated as the dedicated resources.

7. The method of claim 1 further comprising reallocating the non-dedicated resource allocated as a dedicated resource as a non-dedicated resource.

8. A method comprising:

receiving an assignment for a dedicated resource of a random access channel used in communications between network equipment and a first user equipment when the dedicated resource is available

receiving an assignment for non-dedicated resource of a random access channel used in communications between network equipment and the first user equipment when the dedicated resource is blocked;

sending a message on one of the assigned dedicated resource and non-dedicated when the dedicated resource is blocked;

receiving a message indicating that a requested non-dedicated resource is allocated as a dedicated resource by a second user equipment.

9. The method of claim 8 further comprising receiving an identifier indicating that assigned non-dedicated resource is used as a dedicated resource.

10. The method of claim 9 further comprising sending a second message wherein the sending a second message is being associated with the message associated with the non-dedicated resource allocated as a dedicated resource.

11. The method of claim 9 further comprising calculating transmit opportunity to transmit on the assigned non-dedicated resource as dedicated resource when the identifier is not received.

12. The method of claim 11 further comprising sending a second message associated with the sending of the message on non-dedicated resource allocated as a dedicated resource when the identifier is received.

13. The method of claim 8 further comprising:

selecting a non-dedicated resource;

transmitting on the selected non-dedicated resource, when one of a dedicated resource and a non-dedicated resource allocated as dedicated is not assigned;

determining if an identifier is received in response to the sending on a selected non-dedicated resource to determine if it is used as a dedicated resource, and

calculating transmit opportunity to select and transmit on another non-dedicated resource when the identifier is received.

14. The method of claim 13 further comprising sending message associated with the transmission of the message on the non-dedicated resource when the identifier is not received.

15. The method of claim 8 wherein the random access channel includes a first region associated with the dedicated resource and a second region associated the non-dedicated resource.

16. The method of claim 9 further comprising:

determining a second identifier is received;

sending a message when the second identifier is not received, and

waiting for another opportunity to transmit on one of the assigned dedicated resource and the non-dedicated resources allocated as a dedicated resource.

17. The method of claim 16 further comprising sending a message associated with the transmission of the message on one of the assigned dedicated resource and the assigned non-dedicated resource allocated as dedicated resource.

18. A method comprising:

dividing a resource into a set of dedicated resources and a set of non-dedicated resources wherein the dedicated and non-dedicated resources are a part of a random access channel used in communications between network equipment and a first user equipment;

allocating one of the set of dedicated resources to one of the network equipment and the first user equipment when the dedicated resource is available;

allocating one of the set of non-dedicated sub-resources to one of the network equipment and the first user equipment requesting a non-dedicated sub-resource;

allocating one of the set of non-dedicated sub-resources to one of the network equipment and user equipment as the set of dedicated resources when the dedicated resources are blocked, and

sending a message indicating that the allocated one of the set of non-dedicated sub-resources is allocated as the set of dedicated resources when the non-dedicated resources is requested as a non-dedicated resource by a second user equipment.
