A resource scheduling method and base station

Abstract

The present application discloses a resource scheduling method and a base station, which are used to eliminate the transmission time delay between the baseband unit and the remote radio unit, so that resource scheduling can be performed normally, and avoid waste of scheduling resources. The method of this application includes: the radio remote unit receives the new transmission management frame sent by the baseband unit; the radio remote unit decodes the uplink data sent by the terminal to obtain a decoding result; if the radio remote unit After receiving the retransmission management frame sent by the baseband unit, the radio remote unit sends first confirmation information to the terminal according to the decoding result, and the first confirmation information includes the new transmission management frame or the retransmission management frame; if the radio frequency unit does not receive the retransmission management frame, the radio remote unit sends second confirmation information to the terminal, and the second confirmation information is used to indicate the Do not perform resource scheduling for the HARQ process for the first time, and wait for the next resource scheduling.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a resource scheduling method and a base station. Background technique [0002] In the long term evolution (LTE) technology, the base station architecture in the mobile communication network adopts a distributed base station architecture, that is, the base station is divided into a near-end unit and a remote unit, wherein the near-end unit is also called a baseband unit (BBU). ), the remote unit is also called a radio remote unit (radio remote unit, RRU), and the BBU and the RRU are connected through an optical fiber. [0003] During the uplink scheduling process of the base station, when the process starts, the BBU sends the uplink transmission resource scheduling, and sends the scheduling result to the RRU. After the RRU receives the uplink data sent by the user equipment (UE), the RRU performs Decode and obtain the decoding result. After the BBU rece...

Problems solved by technology

[0004] In the above-mentioned uplink scheduling process, if the distance between the BBU and the RRU is relatively long, it will take a long time for the above-mentioned decoding result to be sent by the BBU to the RRU, so that the time when the BBU receives the above-mentioned decoding result is already at the end of the process. After the scheduling time, the scheduling time is missed. In this case, the process scheduling cannot be carried out this time, and it can only be suspended until the next process scheduling. Therefore, the transmission delay between the BBU and the RRU is too large, which will cause hybrid automatic re-starting. The hybrid automatic repeat request (HARQ) process is suspended, and scheduling resources cannot be used for new transmission or retransmission scheduling, resulting in waste of resources
