102, base station scrambles time window configuration information.
Base station is by the time window configuration information of configuration with new radio network temporary identifier (radio network tempory identity, RNTI it) is scrambled, the new RNTI is used for identified time window configuration information, wherein, new RNTI can be understood as a scramble sequence, base station scrambles time window configuration information, the time window configuration information is interfered with a scramble sequence, change the time window configuration information, only being descrambled using identical scramble sequence could restore, therefore time window configuration information is scrambled by new RNTI for base station so that terminal can distinguish the time window configuration information.
103, base station sends first message to terminal.
After base station scrambles time window configuration information, terminal is sent by first message by the time window configuration information, wherein, the first message can be semi-persistent scheduling signaling, such as wireless heterogeneous networks (radio resource control, RRC) signaling, or be medium access control (media access control, MAC) CE signaling, specifically herein without limitation.
Wherein, in the embodiment of the present application, terminal can be referred to as user equipment (User Equipment again, UE), it can be a kind of equipment for providing a user voice and/or data connectivity, for example, handheld device, mobile unit etc. with wireless connecting function.Common terminal for example, mobile phone, tablet computer, laptop, palm PC, mobile internet device (mobile internet device, MID), wearable device, such as smartwatch, Intelligent bracelet, pedometer etc..
