Method for scheduling communication resource, terminal device and base station

A method for scheduling communication resource, comprising:

• receiving an access request message from a terminal, wherein the access request message indicates that the terminal has a demand on transmitting data with a short time delay;
• generating and transmitting a first allocation message to the terminal based on the access request message, wherein the first allocation message comprises information of a first scheduling request resource that is used for transmitting a scheduling request of the data with the short time delay, and information of a second scheduling request resource that is used for transmitting a scheduling request of common data;
• receiving a scheduling request from the terminal;
• if it is determined that the scheduling request is transmitted using the first scheduling request resource, allocating a resource for transmitting the data with the short time delay to the terminal, and generating a second allocation message comprising the allocated resource for transmitting the data with the short time delay;
• and transmitting the second allocation message to the terminal;
• and
• if it is determined that the scheduling request received from the terminal is transmitted using the second scheduling request resource, generating and transmitting a third allocation message to the terminal, wherein the third allocation message comprises information of a resource for transmitting a Buffer Status Report (BSR).

A terminal device, comprising:

• a first transmitting circuitry configured to transmit an access request message to a base station, wherein the access request message indicates that the terminal device has a demand on transmitting data with a short time delay;
• a first receiving circuitry configured to receive a first allocation message from the base station, wherein the first allocation message is generated based on the access request message and comprises information of a first scheduling request resource and information of a second scheduling request resource, wherein the first scheduling request resource is used for transmitting a scheduling request of the data with the short time delay, and the second scheduling request resource is used for transmitting a scheduling request of common data;
• a determining circuitry configured to determine whether data to be transmitted is the data with the short time delay or the common data;
• a second transmitting circuitry configured to:
• if it is determined that the data to be transmitted is the data with the short time delay, transmit a scheduling request of the data with the short time delay to the base station using the first scheduling request resources and if it is determined that the data to be transmitted is the common data, transmit a scheduling request of the common data to the base station using the second scheduling request resource;
• a second receiving circuitry configured to receive a second allocation message from the base station, wherein the second allocation message comprises information of a resource for transmitting the data with the short time delay which is allocated by the base station, and is generated depending only on the base station determining that the first scheduling request resource has been used to transmit the scheduling request by the terminal;
• and
• a third transmitting circuitry configured to transmit the data with the short time delay based on the resource allocated in the second allocation message.

A base station, comprising:

• a first receiving circuitry configured to receive an access request message from a terminal, wherein the access request message indicates that the terminal has a demand on transmitting data with a short time delay;
• a first processing circuitry configured to generate a first allocation message based on the access request message, wherein the first allocation message comprises information of a first scheduling request resource that is used for transmitting a scheduling request of the data with the short time delay, and information of a second scheduling request resource that is used for transmitting a scheduling request of common data;
• a first transmitting circuitry configured to transmit the first allocation message to the terminal;
• a second receiving circuitry configured to receive a scheduling request from the terminal;
• a determining circuitry configured to determine whether the scheduling request is transmitted using the first scheduling request resource;
• a second processing circuitry configured to:
• if it is determined that the scheduling request is transmitted using the first scheduling request resource, allocate a resource for transmitting the data with the short time delay to the terminal, and generate a second allocation message comprising the allocated resource for transmitting the data with the short time delay;
• a second transmitting circuitry configured to transmit the second allocation message to the terminal;
• a third processing circuitry configured to:
• if it is determined that the scheduling request received from the terminal is transmitted using the second scheduling request resource, generate a third allocation message comprising information of a resource for transmitting a Buffer Status Report (BSR);
• and
• a third transmitting circuitry configured to transmit the third allocation message to the terminal.
