Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] A wireless communication network may include a number of base stations capable of supporting communication for a number of wireless user devices. A wireless user device can communicate with a base station via downlinks and uplinks. The downlink (or forward link) refers to the communication link from a base station to a wireless user device, and the uplink ...

Abstract

The invention discloses an uplink-grant-free resource allocation method, user equipment and a base station. The resource allocation method in an embodiment includes: the user equipment acquires resource pool information pre-allocated by the base station, wherein the resource pool includes a plurality of time-frequency domain resources; before uplink grant is received, the user equipment selects one or more time-frequency resources from the resource pool to realize uplink data transmission. Time delay can be effectively reduced while data transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource configuration method free of uplink scheduling permission, user equipment and a base station. Background technique [0002] In the case of traditional LTE (Long Term Evolution), both uplink and downlink transmissions are based on base station scheduling. Before uplink transmission, the user equipment (UE) needs to send a scheduling request (Scheduling Request, SR for short) to the base station, and then the base station sends downlink control information (DCI for short) containing the uplink scheduling (UL grant) to indicate the uplink Time-frequency resources for transmission, modulation and coding schemes, hybrid automatic repeat request (Hybrid Automatic RepeatreQuest, HARQ for short) timing, and the like. [0003] Ultra-Reliable and Low Latency Communications (URLLC) services in the new wireless technology (New Radio, NR for short), because of its h...
