Problems solved by technology

[0003] However, if the terminal device misses the WUS, in the scenario where the PDCCH needs to be monitored, skipping the PDCCH monitoring will cause a large delay in receiving data packets and result in a loss of transmission volume per unit time.

Embodiment Construction

[0068] Embodiments of the present application are described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Those of ordinary skill in the art know that, with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0069] The embodiment of the present application provides a signal transmission method. When the terminal device does not receive the WUS, it can determine whether the network device sends the WUS according to the CSI-RS, so as to reduce the probability of missed detection of the WUS and improve the performance of the system. Each will be described in detail below.

[0070] The terms "first", "second" and the like in the specification and claims of the present application and the above drawings ar...

Abstract

The invention discloses a signal transmission method, which comprises the steps that terminal equipment monitors a wake-up signal WUS and monitors a first channel state information reference signal CSIRS and a second channel state information reference signal CSIRS, the WUS corresponding to the first CSIRS is not sent, and the WUS corresponding to the second CSIRS is sent. When the terminal devicedoes not receive the WUS and the terminal device receives the first CSIRS, the terminal device determines that the WUS is not sent. When the terminal device does not receive the WUS and the terminaldevice receives the second CSIRS, the terminal device determines that the WUS is sent. Through the technical scheme provided by the invention, when the terminal equipment does not receive the WUS, whether the network equipment sends the WUS or not can be determined according to the CSIRS, so that the missed detection probability of the WUS is reduced, and the performance of the system is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a signal transmission method. Background technique [0002] In the third generation partnership project (third generation partnership project, 3GPP) R15 release, for narrowband Internet of things (narrow band internet of things, NB-IoT) and enhanced machine type communication (enhanced Machine Type Communication, eMTC) projects In , a wake upsignaling (WUS) is introduced. Wherein, the WUS is a low power consumption monitoring signal, which is usually placed before the monitoring time of a physical downlink control channel (PDCCH). If the terminal device detects the WUS, it means that it needs to monitor the PDCCH, and if the terminal device does not detect the WUS, it skips the monitoring of the PDCCH. [0003] However, if the terminal device misses the WUS, in the scenario where the PDCCH needs to be monitored, skipping the PDCCH monitoring will cause a la...
