Radio resource configuration method, base station and user equipment

A radio resource configuration method applied for a UE, comprising:

• acquiring an arrival time, the arrival time being a time when the downlink data packet arrives at the PDCP layer of the UE from an RLC layer of the UE and is placed into a reordering window;
• acquiring a delivery time, the delivery time being a time when the downlink data packet is transmitted from the PDCP layer of the UE to a high-layer protocol entity;
• calculating, based on the arrival time and the delivery time, a proportion of data packets whose delay is greater than a predetermined delay threshold within a certain time period, the delay of the data packets being a reordering delay of downlink data packets at the PDCP layer of the UE, the proportion comprising one or more of a proportion in data packets for the UE, a proportion in data packets on a same RB, a proportion in data packets in a same QoS flow, a proportion in data packets received on a same split bearer and through a same path, a proportion in data packets received on a same duplicate bearer and through a same path, a proportion in data packets in a same cell group, and a proportion in data packets of a same bearer type;
• and
• transmitting the calculated proportion to a base station, so that the base station performs the radio resource configuration based on the proportion;
• wherein the downlink data packets for the calculation of the proportion comprise:
• the downlink data packets received within the time period and located in the reordering window, and the downlink data packets located within the reordering window but ignored due to the expiration of the reordering timer at the PDCP layer, wherein a reordering delay of the ignored downlink data packet is a time value of the reordering timer, and the reordering window is a data packet sequence window.
