Problems solved by technology

[0006] In an existing static scheduling technology, the judgment strategy adopted is to always select the static scheduling resource with the smallest serial number (Index). However, the static scheduling resource with the smallest serial number may not be able to meet the URLLC delay requirements, and may also cause EMMB throughput. drop, slow down

Embodiment Construction

[0035] In the prior art, scenarios where the MAC layer in the UE needs to determine the uplink priority include conflicts between dynamic scheduling and static scheduling, conflicts between SR and dynamic scheduling / static scheduling, and conflicts between multiple static scheduling, etc. Condition. Among them, when there is a conflict between multiple static schedules, that is, when multiple phy-PriorityIndex-r16s are the same and there are overlapping uplink transmission opportunities, there is no specification in the UE protocol how to resolve this conflict, and how to determine the value of each static schedule Final priority. In an existing static scheduling technology, the judgment strategy adopted is to always select the static scheduling resource with the smallest serial number. However, the static scheduling resource with the smallest serial number may not be able to meet the URLLC delay requirements, and may also cause the EMMB throughput rate to drop, and the rate ...

Abstract

The invention discloses a static scheduling method and device, a readable storage medium and a terminal. The method comprises the steps: determining the type of data which can be borne by each static scheduling resource when a plurality of static scheduling resources are the same in priority and have conflicts; and in the plurality of static scheduling resources with conflicts, if only one static scheduling resource can bear the URLLC data type, sending data to be sent by adopting the static scheduling resource. According to the method, the type of the data which can be borne by the static scheduling resource is firstly judged, and then the static scheduling resource bearing the URLLC data is preferentially selected to send the to-be-sent data by utilizing the characteristics of relatively small time delay and relatively high reliability of the URLLC data.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a static scheduling method and device, a readable storage medium, and a terminal. Background technique [0002] Wireless communication systems have been widely deployed for daily voice, video, data and short message services. After several stages of development in 2G, 3G and 4G, mobile communication has entered the stage of research and development and deployment of 5G New Radio (NR). The 3rd Generation Partnership Project (3GPP) defines Enhanced Mobile Broadband (EMBB) and Ultra-reliable and Low Latency Communications (URLLC) for 5G. [0003] In order to meet the needs of URLLC services with higher requirements (such as factory automation, transportation, power distribution systems, etc.) ) R16 introduces an uplink cancellation indication (Cancellation indication in UL, CI-RNTI); for the uplink priority within the UE, 5G R16 adds a new UE capability item lch...
