Problems solved by technology

If the wake-up signal mechanism in NR copies the wake-up signal mechanism in LTE, it will consume a lot of time resources in the time domain
Considering the shortage of NR resources, it is difficult to find enough idle downlink time-domain resources to transmit the wake-up signal, so the transmission of the wake-up signal may cause resource collision between the wake-up signal and the Synchronization Signal and physical broadcast channel Block (SSB), or the wake-up signal and the PO resource collision occurs, or wakeup signals associated with different POs collide with each other

Embodiment Construction

[0036] As mentioned in the background art, each PO in LTE is configured with a wake-up signal using different time-domain resources, and the time-domain resource overhead is large, so it is difficult to be directly applied to NR communication.

[0037] Specifically, the radio resource control idle state (Radio Resource Control-IDLE, RRC-IDLE for short) terminal performs the measurement process of cell reselection and monitors the paging PDCCH detection process to consume a lot of power. Among them, the power consumption used for monitoring the paging PDCCH accounts for a larger proportion. For this reason, LTE introduces a Wake Up Signal (Wake Up Signal) with low power consumption for the power consumption of Machine-Type Communication (MTC) terminals and Narrow Band Internet of Things (NB-IoT) terminals. , referred to as WUS), to indicate whether the terminal monitors the PDCCH.

[0038] Those skilled in the art understand that the idle state (ie RRC-IDLE) terminal mainly mo...

Abstract

The invention discloses a method and a device for determining and indicating wake-up signal resources, a terminal and a base station. The determination method comprises the following steps: receivinga wake-up signal indication parameter sent by a network side, wherein the wake-up signal indication parameter indicates one or more of the following information: the paging occasion number contained in paging occasion units and the type of an association relationship between the wake-up signal and each paging occasion in each paging occasion unit, and the type of the association relationship is that the wake-up signal and the paging occasion are associated in a one-to-one correspondence manner or the wake-up signal and the paging occasion are associated in a one-to-many correspondence manner;and extracting the value of the wake-up signal indication parameter to determine resources configured by the wake-up signal. Through the technical scheme provided by the invention, the time domain resource overhead of the wake-up signal can be reduced, and the resource collision probability is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for determining and indicating wake-up signal resources, a terminal, and a base station. Background technique [0002] With the rise of smart terminals, terminal functions are becoming more and more powerful, and terminal power consumption is increasingly affecting user experience, resulting in increasingly strong user demand for terminal energy saving. [0003] For this reason, in the fifth-generation mobile communications (The Fifth-Generation mobile communications, referred to as 5G) new radio (New Radio, referred to as NR, also known as new air interface) technology, the paging mechanism introduces a wake-up signal (Wake Up Signal, Abbreviated as WUS) mechanism to save energy consumption. Since the power consumption of detecting the wake-up signal is far lower than that of detecting the Physical Downlink Control Channel (PDCCH for s...
