Problems solved by technology

[0006] If all information with large payload size is carried in PSBCH, this will lead to excessive payload size of PSBCH
So far, there is no mature implementation on how to reduce the payload size of the message

Embodiment Construction

[0023] With reference to the following drawings, the technical contents, structural features, realized goals and effects of the embodiments of the present disclosure are described in detail. In particular, the terms in the embodiments of the present disclosure are only used for the purpose of describing specific embodiments, rather than limiting the present disclosure.

[0024] In some embodiments, a Physical Sidelink Broadcast Channel (PSBCH) (eg New Wireless Vehicle to Everything PSBCH, NR-V2X PSBCH) is used to indicate information (eg Time Division Duplex configuration, TDD configuration). For a partial coverage scenario, a user equipment (ICUE) located within the coverage of a cell may send a PSBCH carrying information configured by a network node (eg, a base station) to an out-of-coverage UE (OCCUE). Information configured by a network node (such as TDD configuration) is implemented through Radio Resource Control (RRC) signaling or System Information Block (SIB).

Abstract

An apparatus and method for transmitting or receiving a physical sidelink broadcast channel (PSBCH) are provided. The method for sending the PSBCH of the first user equipment comprises the step of sending the PSBCH carrying information to one or more pieces of second user equipment, wherein the information carried in the PSBCH is used for determining a period and the number of time slots. This may reduce the payload size of information carried in the PSBCH.

Description

[0001] public background technical field [0002] The present disclosure relates to the field of communication systems, and more particularly, to apparatus and methods for transmitting or receiving a Physical Sidelink Broadcast Channel (PSBCH). Background technique [0003] Sidelink (SL) technology developed under the 3rd Generation Partnership Project (3GPP) for device-to-device (D2D) wireless communication directly from one user equipment (UE) to another UE, traditionally designed Mission-critical communications for public safety (PS) services and vehicle-to-everything (V2X) communications for intelligent transportation systems (ITS), including road safety use cases. In these applications and services, an important goal is to provide a reliable sidelink (SL) communication system, since the safety of PS personnel and road users such as drivers, riders and pedestrians is at risk. In order to ensure their safety and provide a reliable D2D system, the design of SL communicati...
