example 1

[0104] Example 1, using method 1 to determine the carrier / narrowband position of the indication information, the indication information is used to indicate whether to detect the PDSCH carrying the paging message on one or more POs, and / or the downlink control channel indicating its scheduling information (the following example Both are PDCCH). Specifically, such as image 3 As shown, each UE acquires configuration information of a paging carrier or a paging narrowband, and determines that the indication information is transmitted on a predefined carrier 1 (for example, carrier 1 is an anchor carrier). At this time, each UE will monitor the indication information 1 and the indication information 2 corresponding to the next period on the carrier 1 . If the indication information 1 indicates that there is PDCCH or PDSCH transmission in the corresponding PO, the UE continues to monitor the PDCCH or try to decode the PDSCH according to the rules of the PO. If the indication infor...

Abstract

The disclosure discloses a method for detecting indication information, comprising the following steps: determining a carrier / narrowband location and a time domain location where the indication information is located, wherein the indication information is used to indicate whether the UE monitors a paging message or a downlink control channel indicating the paging message at one or a plurality of paging moments POs; detecting the indication information on the determined carrier / narrowband location and time domain location, and determining, according to the indication information, whether to monitor the paging message or the downlink control channel on the one or a plurality of Pos. By applying the application, the power saving of the terminal can be effectively realized.

Description

technical field [0001] The present invention relates to a wireless communication system, and more specifically relates to a detection method and equipment for indication information. Background technique [0002] For IoT (Internet of things) terminals, power consumption and battery life are very important. In the narrowband Internet of Things NB-IoT (narrow band IoT) or enhanced machine type communication eMTC (enhanced machine type communication) system, you can configure the power saving mode PSM (power saving mode) or extended discontinuous reception eDRX (extended DRX) to To achieve power saving of terminal equipment. However, during sleep periods in PSM or eDRX mode, the UE cannot listen to paging messages. For some IoT applications, it is required that the UE can establish communication with the network within a certain period of time after receiving a network command. Then the UE with these requirements will not be able to be configured in the PSM or eDRX mode with...
