A machine-to-machine (M2M) device for receiving persistent scheduling information in a wireless communication system includes a receiver configured to receive, from a BS, a message comprising allocation period information including a persistent allocation period for the M2M device, wherein the message further comprises de-allocation information that indicates whether the de-allocation corresponds to a permanent de-allocation or one-time de-allocation when the allocation period information indicates a de-allocation, and wherein the message does not comprise information about HARQ feedback allocation when the de-allocation information indicates the one-time de-allocation. ## Claims ### Claim 1 A method of transmitting uplink persistent allocation information at a base station (BS) in a wireless communication system, the method comprising: transmitting, to a machine-to-machine (M2M) device, the uplink persistent allocation information for the M2M device, the uplink persistent allocation information comprising de-allocation information, wherein when the de-allocation information indicates a de-allocation corresponds to a permanent de-allocation, the uplink persistent allocation information further comprises information related to hybrid automatic repeat request (HARQ) feedback allocation for acknowledging receipt of the uplink persistent allocation information, and wherein when the de-allocation information indicates the de-allocation corresponds to a one-time de-allocation, the uplink persistent allocation information does not comprise the information related to the HARQ feedback allocation for acknowledging receipt of the uplink persistent allocation information. ### Claim 2 (depends on 1) The method according to claim 1, wherein when the de-allocation information indicates the one-time de-allocation, a resource indicated by the uplink persistent allocation information is de-allocated in a corresponding uplink subframe and a related persistent allocation is retained. ### Claim 3 (depends on 1) The method according to claim 1, wherein a related persistent allocation is terminated when the de-allocation information indicates the permanent de-allocation. ### Claim 4 (depends on 1) The method according to claim 1, wherein the uplink persistent allocation information further comprises an uplink M2M persistent allocation A-MAP IE (Information Element) message. ### Claim 5 A method of receiving uplink persistent allocation information at a machine-to-machine (M2M) device in a wireless communication system, the method comprising: receiving, from a base station (BS), the uplink persistent allocation information for the M2M device, the uplink persistent allocation information comprising de-allocation information, wherein when the de-allocation information indicates a de-allocation corresponds to a permanent de-allocation, the uplink persistent allocation information further comprises information related to hybrid automatic repeat request (HARQ) feedback allocation for acknowledging receipt of the uplink persistent allocation information, and wherein when the de-allocation information indicates the de-allocation corresponds to a one-time de-allocation, the uplink persistent allocation information does not comprise the information related to the HARQ feedback allocation for acknowledging receipt of the uplink persistent allocation information. ### Claim 6 (depends on 5) The method according to claim 5, wherein when the de-allocation information indicates the one-time de-allocation, a resource indicated by the uplink persistent allocation information is de-allocated in a corresponding uplink subframe and a related persistent allocation is retained. ### Claim 7 (depends on 5) The method according to claim 5, wherein a related persistent allocation is terminated when the de-allocation information indicates the permanent de-allocation. ### Claim 8 (depends on 5) The method according to claim 5, wherein the M2M device does not transmit an HARQ feedback for receipt of the uplink persistent allocation information when the de-allocation corresponds to the one-time de-allocation. ### Claim 9 (depends on 5) The method according to claim 5, wherein the uplink persistent allocation information further comprises an uplink M2M persistent allocation A-MAP IE (Information Element) message. ### Claim 10 A base station (BS) for transmitting uplink persistent allocation information in a wireless communication system, the BS comprising: a transmitter; and a processor configured to control: the transmitter to transmit, to a machine-to-machine (M2M) device, the uplink persistent allocation information for the M2M device, the uplink persistent allocation information comprising de-allocation information, wherein when the de-allocation information indicates the de-allocation corresponds to a permanent de-allocation, the uplink persistent allocation information further comprises information related to hybrid automatic repeat request (HARQ) feedback allocation for acknowledging receipt of the uplink persistent allocation information, and wherein when the de-allocation information indicates the de-allocation corresponds to a one-time de-allocation, the uplink persistent allocation information does not comprise the information related to the HARQ feedback allocation for acknowledging receipt of the uplink persistent allocation information. ### Claim 11 A machine-to-machine (M2M) device for receiving uplink persistent allocation information in a wireless communication system, the M2M device comprising: a receiver; and a processor configured to control: the receiver to receive, from a base station (BS), the uplink persistent allocation information for the M2M device, the uplink persistent allocation information comprising de-allocation information, wherein when the de-allocation information indicates a de-allocation corresponds to a permanent de-allocation, the uplink persistent allocation information further comprises information related to hybrid automatic repeat request (HARQ) feedback allocation for acknowledging receipt of the uplink persistent allocation information, and wherein when the de-allocation information indicates the de-allocation corresponds to a one-time de-allocation, the uplink persistent allocation information does not comprise the information related to the HARQ feedback allocation for acknowledging receipt of the uplink persistent allocation information. ### Claim 12 (depends on 11) The M2M device according to claim 11, wherein the processor is further configured to control: the transmitter not to transmit an HARQ feedback for receipt of the uplink persistent allocation information when the de-allocation corresponds to the one-time de-allocation. ### Claim 13 (depends on 11) The M2M device according to claim 11, wherein when the de-allocation information indicates the one-time de-allocation, a resource indicated by the uplink persistent allocation information is de-allocated in a corresponding uplink subframe, and wherein the processor is further configured to retain a related persistent allocation. ### Claim 14 (depends on 11) The M2M device according to claim 11, wherein the processor is further configured to terminate a related persistent allocation when the de-allocation information indicates the permanent de-allocation.
