Problems solved by technology

However, for UEs at the enhanced coverage level, this does not give full play to their capabilities, resulting in longer transmission times for uplink channels that could have been successfully transmitted in a short period of time.
This not only wastes resources, but also greatly harms the power consumption of the UE.

Abstract

The invention discloses a semi-static resource scheduling method, which comprises the steps of: monitoring downlink channel control information DCI of a first format group format, and activating semi-static scheduling SPS according to the indication of the DCI of the first format group format; and monitoring DCI of a second format group format, releasing SPS according to the indication of the DCIof the second format group format, wherein the DCI format load size of the second format group format is smaller than that of the first format group format. Compared with the prior art, the scheduledDCI format load size after SPS activation is smaller than that of SPS activation, the power consumption of monitoring and detecting the DCI by means of UE is reduced, the downlink channel scheduling overhead of the SPS is decreased, the service time delay is reduced, and the efficiency of resource utilization is significantly improved. In addition, the invention further discloses user equipment used for semi-static resource scheduling.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a semi-static resource scheduling method, a power control method and corresponding user equipment. Background technique [0002] NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) is an important branch of the Internet of Everything. NB-IoT can be deployed in cellular networks of GSM, UMTS or LTE. For NB-IoT deployed in the LTE network, in order to support the enhanced coverage scenarios of eMTC (enhanced machine type communication) or mMTC (massive machine type communication) applications, and to meet the requirements of high reliability (such as URLLC), it is necessary The transmission is carried out by repetition. Repeated transmission needs to occupy more channel resources of the PDCCH channel (downlink control channel), so reducing the overhead of downlink channel resources is the key to designing high-efficiency NB-IoT. ...
