Abstract

The invention discloses a method and a device for receiving system messages as well as a method and a device for confirming the position of a sending window, wherein the method for receiving the system messages comprises the following steps: confirming the window offset of SI according to the following ways: window_offset is equal to n-1, wherein n is less than or equal to 5; window_offset is equal to n, wherein n is less than or equal to 6, wherein n is a dispatching sequence of the SI; confirming a beginning radio frame of the window of the SI according to the following ways: SFN percent N is equal to frame_offset plus floor (window_offset / 10), wherein the SFN is a system frame number of the radio frame, the frame_offset is frame offset and is an even number or zero; and confirming a beginning subframe of the window of the SI according to the following ways: subframe is equal to (window_offset) percent 10, wherein the subframe is a sequence number of the radio subframe.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for receiving system messages, and a method and device for determining the position of a sending window. Background technique [0002] In a Long-Term Evolution (LTE for short) system, system messages can be divided into a main system message (MIB), a system message block 1 (SIB1) and general system messages (SI). [0003] Wherein, the MIB is sent on a broadcast channel with a fixed sending cycle of 40 milliseconds, and the MIB is repeatedly sent in the #0 subframe of each radio frame within the sending cycle. System Information Block 1 (SIB1) is sent on the downlink shared channel with a fixed scheduling period of 80 milliseconds. SIB1 satisfies the #5 subframe of the wireless frame with SFN%2=0 within the scheduling period (the subframe number starts from 0) to resend. Other system parameters are included in other system information blocks (SIBs). For othe...
