Problems solved by technology

However, multiple UEs with different wireless channel qualities will be connected to an LTE base station, and there may be multiple UEs that have uplink data to send at the same time. These uplink data include large data packets, more bursty data and small data. In the prior art, regardless of whether it is a large data packet or a small data packet, the UE is scheduled according to the UE's scheduling request and the UE's channel quality, and its uplink transmission efficiency is low.

Abstract

The embodiment of the invention discloses a resource scheduling method and device. The method in the embodiment of the present invention includes: receiving the uplink scheduling request sent by the user equipment UE, obtaining the MCS value of the modulation and coding strategy, and sending the MCS value to the UE, so that the UE sends uplink data and sends a buffer status report according to the MCS value, if The received buffer status report indicates that the UE still has to send data, and it is determined that the number of adjustments of the MCS value does not exceed the preset threshold, then obtain the MCS value, and adjust the MCS value upward; send the adjusted MCS value to the UE. The UE is made to send uplink data according to the adjusted MCS value, which effectively improves the uplink transmission efficiency of the UE.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource scheduling method and device. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) system, the link through which the user equipment UE sends data to the base station side is called an uplink. When the UE has data to send, the base station side first allocates radio resources for the UE (including The number of radio beacons (RB, Radio Beacon) and the value of the modulation and coding strategy (MCS, Modulation and CodingScheme), where the number of RBs and the MCS value together determine the size of the transmission block), and then send the scheduling information to the UE , the UE sends a transport block of a corresponding size to the UE within a pre-agreed time window according to the indication of the scheduling information, thus completing an uplink transmission. [0003] According to the principle of wireless communication, the ...
