Abstract

The invention provides a receiving processing method and apparatus of random access response RAR. The method comprises the following steps: determining the overlapping state of a first physical downlink control channel PDCCH decoding area of a first terminal and a second PDCCH decoding area of a second terminal; when it is determined that the overlapping state of the first PDCCH decoding area and the second PDCCH decoding area is overlapped, closing an RAR window used for receiving RAR of the first terminal; and when it is determined that the overlapping state of the first PDCCH decoding area and the second PDCCH decoding area is not overlapped, opening the RAR window, and receiving the RAR in the RAR window. According to the receiving processing method and apparatus, the RAR window used for receiving RAR is temporarily closed, thereby avoiding mis-decoding the DCI not belonging to the terminal and saving the power consumption of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for receiving and processing a random access response RAR. Background technique [0002] Machine to Machine (M2M for short) communication is an important subject of current research in the 5th Generation mobile communication technology (5G for short), and is also an important application field of future wireless communication. In the M2M subject, the 3rd Generation Partnership Project (3rd Gederation Partnership Project, referred to as 3GPP) proposed a narrowband Internet of Things (NB-IoT) system for the low-cost and low-throughput characteristics of terminals. The research sub-topic of this project aims to build a system similar to Long-Term Evolution (LTE) in the 200KHz frequency band to provide low-throughput wireless communication services for low-cost terminals. Orthogonal Frequency Division Multiple Access (OFDMA) technology is still used in the downl...
