摘要
A user device for transmitting and receiving data to and from an infrastructure equipment via a wireless access interface. The user device is configured to receive an indication from the infrastructure equipment of a location and duration of a temporal response window for receiving response messages, the response messages being received in response to access request messages and the location and duration of the temporal response window having been determined by the infrastructure equipment. The user device is configured to transmit an access request message for requesting access to the wireless access interface to the infrastructure equipment, and to receive a response message in response to the access request message from the infrastructure equipment, wherein the user device is configured to receive the response message in the temporal response window.

The invention claimed is:1. A wireless user device comprising:circuitry configured to: receive a duration of a temporal response window from an infrastructure equipment; transmit an access request message for requesting access to the infrastructure equipment over a relay path, the relay path including a plurality of nodes used to relay the access request message from the wireless user device to the infrastructure equipment; in response to the access request message, receive a response message within the duration of the temporal response window from the infrastructure equipment; receive the response message in one or more of a plurality of temporal response windows, the plurality of temporal response windows separated in time, durations of the temporal response windows having been determined by the infrastructure equipment; and receive a duration of at least one of the temporal response windows from the infrastructure equipment. 2. The wireless user device according to claim 1 , wherein the circuitry is further configured to receive the duration of at least one of the temporal response windows from the infrastructure equipment prior to the transmission of the access request message. 3. The wireless user device according to claim 1 , wherein the circuitry is further configured to enter a reduced power state during the time separating the temporal response windows. 4. The wireless user device according to claim 1 , wherein the circuitry is further configured to receive the duration of at least one of the temporal response windows from the infrastructure equipment in one of the temporal response windows. 5. The wireless user device according to claim 1 , wherein the circuitry is further configured to determine the duration of the at least one of the temporal response windows based on an identifier of the wireless user device and a predetermined rule. 6. The wireless user device according to claim 5 , wherein the circuitry is further configured to receive the duration of at least one of the temporal response windows from the infrastructure equipment that determines the duration of at least one of the temporal response windows based upon the identifier of the wireless user device and the predetermined rule. 7. The wireless user device according to claim 1 , wherein the wireless user device is a 3GPP LTE compliant device. 8. The wireless user device according to claim 1 , wherein the access request message includes a random access preamble and the response message is a random access response. 9. A method for a wireless user device, the method comprising:receiving a duration of a temporal response window from an infrastructure equipment; transmitting an access request message for requesting access to the infrastructure equipment over a relay path, the relay path including a plurality of nodes used to relay the access request message from the wireless user device to the infrastructure equipment; in response to the access request message, receiving a response message within the duration of the temporal response window from the infrastructure equipment; receiving the response message in one or more of a plurality of temporal response windows, the plurality of temporal response windows separated in time, durations of the temporal response windows having been determined by the infrastructure equipment; and receiving a duration of at least one of the temporal response windows from the infrastructure equipment. 10. The method according to claim 9 , the method further comprising:receiving the duration of at least one of the temporal response windows from the infrastructure equipment prior to the transmission of the access request message. 11. The method according to claim 9 , the method further comprising: entering a reduced power state during the time separating the temporal response windows. 12. The method according to claim 9 , the method further comprising:receiving the duration of at least one of the temporal response windows from the infrastructure equipment in one of the temporal response windows. 13. The method according to claim 9 , the method further comprising:determining the duration of the at least one of the temporal response windows based on an identifier of the wireless user device and a predetermined rule. 14. The method according to claim 13 , the method further comprising:receiving the duration of at least one of the temporal response windows from the infrastructure equipment that determines the duration of at least one of the temporal response windows based upon the identifier of the wireless user device and the predetermined rule. 15. The method according to claim 9 , the method further comprising:transmitting and receiving data to and from the wireless user device according to a 3GPP LTE protocol. 16. The method according to claim 9 , the method further comprising:transmitting the access request message including a random access preamble for requesting access to the infrastructure equipment; and receiving the response message, which is a random access response, within the duration of the temporal response window from the infrastructure equipment.
