Method, system and device for triggering scheduling information reporting

A method for triggering scheduling information reporting, the method comprising:

• receiving, by a Base Station (BS), scheduling information reporting triggered by a terminal, determining whether state transition occurs at the terminal or determining whether an Enhanced Dedicated Channel (E-DCH) Radio Network Temporary Identifier (E-RNTI) changes, according to the scheduling information reported;
• when determining the state transition occurs at the terminal or the E-RNTI changes, determining, by the BS, a new data transmission format or a new E-RNTI for the terminal;
• wherein determining by the BS the state transition occurs at the terminal or the E-RNTI changes, according to the scheduling information reported, comprises,
• when the terminal reports the scheduling information via an Enhanced Random Uplink Control Channel (E-RUCCH), detecting, by the BS, the E-RNTI carried in the E-RUCCH;
• when detecting the E-RNTI is a new E-RNTI, determining the E-RNTI of the terminal changes, and
• when the terminal reports the scheduling information with a new grant, determining, by the BS, whether there is an ongoing uplink data transmission of the terminal, by detecting new resources, and when determining there is an ongoing uplink data transmission of the terminal by detecting the new resources, determining the state transition occurs at the terminal, and determining the new data transmission format for the terminal.

A terminal, comprising a determining module and a triggering module;

• wherein
• the determining module is to determine whether state transition occurs at the terminal or whether an Enhanced Dedicated Channel (E-DCH) Radio Network Temporary Identifier (E-RNTI) changes;
• and
• the triggering module is to adopt reconfigured resources or a new E-RNTI to trigger scheduling information reporting, when the state transition occurs at the terminal or the E-RNTI changes;
• wherein the triggering module is to select different carrying modes of the scheduling information to report the scheduling information, according to whether there is a grant for sending new data within current sub-frame or extended window;
• wherein the triggering module is to send the scheduling information about grant request type via an Enhanced Random Uplink Control Channel (E-RUCCH), when there is no available grant for sending the new data within current sub-frame or extended window;
• and
• the triggering module is to send the scheduling information about scheduling request type with the grant, when there is the available grant within current sub-frame or extended window.

A Base Station (BS), comprising a receiving module and a state determining module, wherein

• the receiving module is to receive scheduling information reported by a terminal;
• and
• the state determining module is to determine whether state transition occurs at the terminal or an Enhanced Dedicated Channel (E-DCH) Radio Network Temporary Identifier (E-RNTI) changes, according to the scheduling information reported;
• when the terminal reports the scheduling information via an Enhanced Random Uplink Control Channel (E-RUCCH), the state determining module is to detect the E-RNTI carried by the E-RUCCH, when determining the E-RNTI is a new E-RNTI, the state determining module is to determine the E-RNTI of the terminal changes;
• and
• when the terminal reports the scheduling information with a new grant, the state determining module is to detect whether there is an ongoing uplink data transmission of the terminal from new resources, when determining there is an ongoing uplink data transmission of the terminal from the new resources, the state determining module is to determine the state transition occurs at the terminal.
