The present disclosure relates to transmission methods and devices in wireless communication systems, and in particular to a scheme and a device for measurement in wireless communication.
Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary session decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). The work Item (WI) of NR was approved at the 3GPP RAN #75 plenary session to standardize the NR. Compared with the existing LTE systems, 5G NR has an outstanding feature of supporting more flexible Numerologies, which includes Subcarrier Spacing (SCS) and Cyclic Prefix (CP), and more flexible frame structures, such as of mini-slot, sub-slot and slot aggregation. With such flexible numerologies and frame structures, various new business requirements will be better satisfied, especially in highly diversified vertical industries.
In response to rapidly growing Vehicle-to-Everything (V2X) traffic, 3GPP has started standards setting and research work under the framework of NR. Currently, 3GPP has completed planning work targeting 5G V2X requirements and has included these requirements into standard TS22.886, where 3GPP identifies and defines 4 major Use Case Groups, covering cases of Vehicles Platooning, supporting Extended Sensors, Advanced Driving and Remote Driving. At 3GPP RAN #80 Plenary Session, the technical Study Item (SI) of NR V2X was approved.
A stricter payload balance control is a significant characteristic that differentiates V2X from traditional cellular network, since effective payload control can reduce the probability of business conflicts and improve transmission reliability, which are critical factors for successful V2X. In LTE V2X system, however, a measurement mechanism for payload control is designed based on a single Numerology, namely, 15 kHz SCS, normal length of CP and 1 ms of subframe length, making it impossible to meet the requirement of more flexible Numerology of 5G NR V2X.
In view of the above problem, the present disclosure provides a solution. It should be noted that the embodiments of a User Equipment (UE) in the present disclosure and the characteristics of the embodiments may be applied to a base station if no conflict is incurred, and vice versa. The embodiments of the present disclosure and the characteristics of the embodiments may be mutually combined if no conflict is incurred.
