Problems solved by technology

[0007] 1. If the timeslot is repeated too many times, it will not only waste wireless resources, but also consume terminal power and affect service delay;
[0008] 2. If the number of repeated time slots is too small and the demodulation of the base station fails, it will bring about a second retransmission, which will indirectly waste wireless resources, increase terminal energy consumption, and affect service delay;

Abstract

The invention discloses a 5G uplink coverage enhancement method, which comprises the following steps of: 1, establishing an uplink coverage quality grade table corresponding to a dynamic interval of a reference signal SINR, and establishing a mapping relation table between the uplink coverage quality grade table and time slot repetition times; step 2, determining the uplink coverage quality level of the 5G terminal in the idle state; 3, judging whether the 5G terminal in the inactive state is a mobile terminal or not; step 4, determining the uplink coverage quality grade of the 5G mobile terminal in the inactive state; step 5, determining the uplink coverage quality grade of the 5G non-mobile terminal in the inactive state; according to the invention, the uplink coverage quality level is adaptively determined through the SINR measurement value of the uplink physical signal, the uplink block error rate (BLER) and the power headroom (PHR) reported by the terminal, and the number of time slots needing to be aggregated is obtained through the pre-established mapping table of the uplink coverage quality level and the time slot repetition times, so that the uplink coverage is improved, and wireless resources are saved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for enhancing 5G uplink coverage. Background technique [0002] The three major application scenarios of 5G include eMBB, URLLC, and mMTC. As the technical direction of the Internet of Everything, mMTC mainly focuses on performance indicators such as wide connection, low latency, small packet data transmission, reliability, and wide coverage; at the same time, compared with LTE's Idle (idle) state and connected (connected) state, 5G introduces a new inactive (inactive) state in the RRC state. with; [0003] In mobile communication networks, uplink coverage is generally limited. Especially in 5G mMTC application scenarios, coverage cannot be limited and as many IoT terminals as possible can be accessed, but many terminals may be distributed at the edge of the cell. At this time, the uplink coverage It will face great challenges; in a known network, hardware...
