Abstract

A method, a UE and a communications system for releasing resources are disclosed. When the UE is in a CELL_FACH state, a resource release indication is transmitted from a network equipment to the UE to instruct the UE to release HS-RACH resources on the UE. Upon receiving the resource release indication, the UE releases previously allocate HS-RACH resources on the UE.

First claim

What is claimed is:

1. A user equipment (UE) comprising:
a transmitter configured to send uplink data to a network equipment using allocated high speed random access channel (HS-RACH) resources and transmit an empty buffer status report indicating that the UE has no data for transmission to the network equipment;
a receiver configured to receive a resource release indication from the network equipment, the received release indication being configured to instruct the UE to release the allocated (HS-RACH) resources; and
a processor configured to release the allocated HS-RACH resources of the UE in response to the resource release indication, wherein the UE is in a Cell_Forward Access Channel (CELL_FACH) state.

2. The UE of claim 1 , wherein the resource release indication is included in a media access control (MAC) control packet data unit (PDU) sent to the UE.

3. The UE of claim 1 , wherein the resource release indication is included in a physical layer control signaling sent to the UE.

4. The UE of claim 1 , wherein the empty buffer status report is transmitted to the network equipment through scheduling information (SI).

5. The UE of claim 1 , wherein the empty buffer status report is transmitted to the network equipment through a media access control (MAC) control packet data unit (PDU).

6. A method for releasing resources, comprising:
sending, by a user equipment (UE) in a Cell_Forward Access Channel (CELL_FACH) state, uplink data to a network equipment using allocated high speed random access channel (HS-RACH) resources;
transmitting, by the UE, an empty buffer status report indicating that the UE has no data for transmission to the network equipment;
receiving, by the UE, a resource release indication from the network equipment, the received release indication being configured to instruct the UE to release the allocated HS-RACH resources;
releasing, by the UE, the allocated HS-RACH resources of the UE in response to the received resource release indication.

7. The method of claim 6 , wherein the resource release indication is included in a media access control (MAC) control packet data unit (PDU) sent to the UE.

8. The method of claim 6 , wherein the resource release indication is included in a physical layer control signaling sent to the UE.

9. The method of claim 6 , wherein the empty buffer status report is transmitted to the network equipment through scheduling information (SI).

10. The method of claim 6 , wherein the empty buffer status report is transmitted by the UE through a layer 2 (L 2 ) signaling.

11. A user equipment (UE) comprising:
a transmitter to send uplink data to a network equipment using allocated high speed random access channel (HS-RACH) resources and transmit an empty buffer status report indicating that the UE has no data for transmission to the network equipment;
a receiver to receive a resource release indication from the network equipment, the received release indication instructing the UE to release the allocated HS-RACH resources; and
a processor to release the allocated HS-RACH resources of the UE in response to the resource release indication, wherein the UE is in a Cell_Forward Access Channel (CELL_FACH) state.

12. The UE of claim 11 , wherein the resource release indication is included in a media access control (MAC) control packet data unit (PDU) sent to the UE.

13. The UE of claim 11 , wherein the resource release indication is included in a physical layer control signaling sent to the UE.

14. The UE of claim 11 , wherein the empty buffer status report is transmitted to the network equipment through scheduling information (SI).

15. The UE of claim 11 , wherein the empty buffer status report is transmitted to the network equipment through a media access control (MAC) control packet data unit (PDU).
