[0045] Such as figure 2 As shown, the embodiment of the present invention provides a system message transmission method, which specifically includes the following steps:

[0046] Step 21: Obtain the scheduling information sent by the network device.

[0047] Wherein, the scheduling information refers to scheduling information of a downlink transmission channel, and the downlink transmission channel may be a downlink transmission channel for transmitting downlink data signals, such as: PDSCH, or may be a downlink transmission channel for transmitting downlink control signals, such as PDCCH or ePDCCH. Wherein, the scheduling information is transmitted in a downlink control channel (PDCCH or ePDCCH), and the scheduling information carries information such as resource positions occupied by the network equipment for the scheduled downlink transmission channel. Wherein, the scheduling information may be transmitted in the DCI bearing the DL grant.

[0055] Such as image 3 As shown, the second embodiment of the present invention provides a system message transmission method, which specifically includes the following steps:

[0056] Step 31: Obtain the scheduling information sent by the network device.

[0057] Step 32: Perform descrambling analysis on the scheduling information through the wireless network temporary identification information, and determine the transmission subframes scheduled by the network device for the first system message and the second system message.

[0058] When the UE performs blind detection on the scheduling information, it conducts descrambling analysis through Radio Network Temporary Identity (RNTI, Radio Network Temporary Identity), so as to determine the eSIB and SI transmission subframes. It should be pointed out that when the UE determines that the current transmission subframe is a DRS subframe according to the detected DRS, the eSIB will be transmitted in the DRS subframe by default. ...

[0064] Such as Figure 4 As shown, the third embodiment of the present invention provides a system message transmission method, which specifically includes the following steps:

[0065] Step 41: Obtain the scheduling information sent by the network device.

[0066] Step 42: Obtain the value of a specific field in the scheduling information.

[0067] Step 43: According to the value of the specific field, determine whether the transmission subframes scheduled by the network device for the first system message and the second system message are the same.

[0068] Wherein, obtaining the value of a specific field in the DCI where the scheduling information is located can be realized by performing descrambling analysis on the DCI through the temporary identification information of the wireless network. Specifically, a preset RNTI (such as SI-RNTI) is used to descramble the DCI, and the value of a specific field in the DCI can be obtained after the descrambling is successful. When ...

Abstract

The present invention provides a system message transmission method, device, user terminal and network equipment. The method includes: acquiring scheduling information sent by the network equipment; and determining the network equipment as the first system message and the second system message according to the scheduling information The scheduled transmission subframe; wherein, the first system message is a first type of system message; the second system message is a second type of system message; receiving the first system message and / or the second system message sent by the network device using the transmission subframe Two system messages. The present invention determines the transmission subframes scheduled by the network equipment for the first system message and the second system message through the scheduling information, thereby indicating whether the first system message and the second system message use the same transmission subframe for transmission, and can increase one transmission The transmission quantity of the system message in the subframe, thereby reducing the impact caused by the increase of the sending period of the system message caused by the failure of the LBT.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a system message transmission method, device, user terminal and network equipment. Background technique [0002] A mobile communication system refers to a system in which operators provide communication services for user terminals (such as mobile phones) by deploying wireless access network equipment (such as network equipment) and core network equipment (such as Home Location Register, HLR), etc. system. Mobile communication has experienced the first generation, second generation, third generation, and fourth generation. The first generation of mobile communication refers to the initial analog, voice-only cell phone standard, which mainly uses analog technology and frequency division multiple access (FDMA) access method; the second generation of mobile communication introduces Digital technology has increased network capacity, improved voice quality and confiden...
