Abstract

A node of a radio access network comprises processor circuitry (30) and transmitter circuitry (34). The processor circuitry (30) generates a synchronization signal block comprising a Physical Broadcast Channel (PBCH) and a demodulation reference signal for the Physical Broadcast Channel (PBCH) from which demodulation reference signal a parameter of the radio access network can be determined. The transmitter circuitry transmits the synchronization signal block and the demodulation reference signal over a radio interface (24).

Description

[0001] This application claims priority and benefit to U.S. Provisional Patent 62 / 520,434, entitled "METHOD AND APPARATUS FORGENERATING AND USING REFERENCE SIGNAL PHYSICAL FOR BROADCAST CHANNEL FORRADIO SYSTEM," filed June 15, 2017 and incorporated by reference in its entirety Incorporated into this article. technical field [0002] The present technology relates to wireless communications, and in particular to methods and apparatus for generating and using reference signals, and in particular, demodulation reference signals for physical broadcast channels (PBCH). Background technique [0003] In a wireless communication system, a radio access network typically includes one or more access nodes, such as base stations, that communicate with a plurality of wireless terminals over a radio channel over a radio or air interface. In some technologies, such wireless terminals are also referred to as user equipment (UE). A group known as the 3rd Generation Partnership Project ("3GP...
