Priority scheduling method, user equipment, and base station

A priority scheduling method, comprising:

• receiving an enhanced BSR reported by supporting user equipment (S-UE), wherein the enhanced BSR carries buffer data status information of multiple B-UEs buffered by the S-UE;
• determining, according to the buffer data status information, priorities of performing data transmission on the multiple B-UEs;
• sending uplink scheduling information to the S-UE, wherein the uplink scheduling information carries the priorities of performing data transmission on the multiple B-UEs, so that the S-UE encapsulates some or all of currently buffered data of the multiple B-UEs into one MAC PDU according to the priorities of performing data transmission on the multiple B-UEs;
• and
• receiving the MAC PDU transmitted by the S-UE.

User equipment, comprising:

• a status report generating unit, configured to generate an enhanced buffer status report (BSR) according to buffered data information of multiple B-UEs;
• a status report reporting unit, configured to report, to a base station eNB, the enhanced BSR generated by the status report generating unit, wherein the enhanced BSR carries buffer data status information of each B-UE, so that the eNB determines, according to the buffer data status information, priorities of performing data transmission on the multiple B-UEs;
• a scheduling information receiving unit, configured to:
• after the status report reporting unit reports the enhanced BSR, receive uplink scheduling information delivered by the eNB, wherein the uplink scheduling information carries the priorities of performing data transmission on the multiple B-UEs;
• a data packaging unit, configured to encapsulate some or all of currently buffered data of the multiple B-UEs into one MAC PDU according to the priorities, received by the scheduling information receiving unit, of performing data transmission on the multiple B-UEs;
• and
• a data sending unit, configured to transmit, to the eNB, the MAC PDU obtained by packaging by the data packaging unit.

A base station, comprising:

• a device information receiving unit, configured to receive an enhanced BSR reported by supporting user equipment (S-UE), wherein the enhanced BSR carries buffer data status information of multiple B-UEs buffered by the S-UE;
• a priority determining unit, configured to determine, according to the buffer data status information received by the device information receiving unit, priorities of performing data transmission on the multiple B-UEs;
• a scheduling information sending unit, configured to send uplink scheduling information to the S-UE, wherein the uplink scheduling information carries the priorities, determined by the priority determining unit, of performing data transmission on the multiple B-UEs, so that the S-UE encapsulates some or all of currently buffered data of the multiple B-UEs into one MAC PDU according to the priorities of performing data transmission on the multiple B-UEs;
• and
• a data receiving unit, configured to receive the MAC PDU transmitted by the S-UE.
