Technical field

The present invention relates to the field of communications technologies, and in particular, to a blind detection method, a system information transmission method, and a device.

Background technique

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access techniques capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power). Examples of such multiple access techniques include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, and Frequency Division Multiple Access (FDMA) systems. Orthogonal Division Multiple Access (OFDMA) system, Single-carrier Frequency-Division Multiple Access (SC-FDMA) system.

These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the city, national, regional, and even global levels. An example of an emerging telecommunication standard is Long Term Evolution (LTE/LTE-A). LTE/LTE-A is an enhanced set of Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the Third Generation Partnership Project (3GPP). LTE/LTE-A is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing cost, improving service, utilizing new spectrum, and using orthogonal frequency division on the downlink (DL) Orthogonal Division Multiple Access (OFDMA), single-carrier frequency-division multiple access (SC-FDMA) on the uplink (UL), and multi-input multiple-output (Multi) Input Multi Output, MIMO) Other open standards for antenna technology for better integration. However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in LTE technology. Preferably, these improvements should apply to other multiple access technologies and telecommunications standards that employ these technologies.

The terms "network" and "system" are often used interchangeably. A CDMA network may implement a wireless technology such as Universal Telecommunication Radio Access (UTRA), Telecommunications Industry Association (TIA).

UTRA and E-UTRA technologies are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE-A) are newer versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). UMB is described in documents from an organization called "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used for the wireless networks and wireless access technologies mentioned above, as well as other wireless networks and wireless access technologies. For clarity, certain aspects of the technology are described below for LTE or LTE-A (or collectively referred to as "LTE/-A"), and such LTE/-A terminology is used in many of the descriptions below.

It should be noted that the wireless communication network may include multiple base stations capable of supporting communication of multiple user equipments. The user equipment can communicate with the base station over the downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the user equipment, and the uplink (or reverse link) refers to the communication link from the user equipment to the base station.

A user equipment UE (e.g., a cellular telephone or a smart phone) can utilize a wireless communication system to transmit and receive data for two-way communication. The user equipment may include a transmitter for data transmission and a receiver for data reception. For data transmission, the transmitter can modulate the transmit Local Oscillator (LO) signal with data to obtain a modulated Radio Frequency (RF) signal, and amplify the modulated RF signal to obtain proper transmission. The RF signal is output at the power level and the output RF signal is transmitted to the base station via the antenna. For data reception, the receiver can obtain the received RF signal via an antenna, amplify and downconvert the received RF signal with the received LO signal, and process the downconverted signal to recover the data transmitted by the base station.

The user equipment can support communication with multiple wireless systems of different Radio Access Technology (RAT) (eg, LTE/LTE-A and NR). Each wireless system may have certain characteristics and requirements to efficiently support simultaneous communication of wireless systems utilizing different RATs. User equipment may include mobile stations, terminals, access terminals, subscriber units, stations, and the like. The user equipment can also be a cellular phone, a smart phone, a tablet computer, a wireless modem, a personal digital assistant (PDA), a handheld device, a laptop computer, a smartbook, a netbook, a cordless phone, a wireless local loop (wireless Local loop, WLL) site, Bluetooth device, and more. The user equipment may be capable of communicating with the wireless system, and may also be capable of receiving signals from a broadcast station, one or more satellites in a Global Navigation Satellite System (GNSS), or the like. The user equipment may support one or more RATs for wireless communication, such as GSM, WCDMA, CDMA2000, LTE/LTE-A, 802.11, and the like. The terms "radio access technology", "RAT", "radio technology", "air interface" and "standard" are often used interchangeably.

It should be noted that in the LTE/LTE-A system, the uplink/downlink carriers adopt Single-Carrier Frequency-Division Multiple Access (SC-FDMA)/OFDM and Cyclic Prefix (CP) respectively. ). In the 5G (eg, NR) standard, for example, the uplink and downlink carriers may be unified, that is, both uplink and downlink adopt OFDM and CP. In another example, the RB in the 5G may be configured as follows, one resource block includes 12 subcarriers, the subcarrier spacing is based on 15 kHz, and the subcarrier spacing may be N (N=2^n) times of 15 kHz, or It can also be fixed to a subcarrier spacing of 75 kHz. Specifically, the bandwidth of the traditional LTE cell working in the frequency band is composed of RBs, and the RBs have fixed subcarrier spacing and symbol length respectively. For example, under normal CP, the size in the frequency domain is 180 kHz (ie, 12 15 kHz subcarriers). Interval), including 7 symbols in the time domain, the length of one symbol is approximately equal to 71.5us. In the next generation of 5G mobile communication technologies (for example, in the NR system), different subcarriers may no longer have a fixed subcarrier spacing and a fixed symbol length (which may be dynamically changed) based on the traffic type. In order to distinguish it from the RB concept in the traditional LTE system, the NR system newly defines the concept of "numerology" (reference value), which mainly includes subcarrier spacing, CP length, and TTI (Transmission Time Interval) length. Currently, the NR system defines three service types, namely eMBB, URLLC, and mMTC. The "numerology" types of different service types may also be different, meaning that different types of subcarrier spacing, CP length, or TTI length may be different. Illustratively, it can be defined that next generation mobile communications will support a single carrier bandwidth of up to 100 MHz. The size of one resource block RB in the frequency domain becomes 900 KHz (ie, 12 75 KHz subcarrier intervals), and 0.1 ms is supported in the time domain. The length of one radio frame is 10 ms, but consists of 50 subframes, each of which has a length of 0.2 ms. It should be noted that the signal type applicable to the NR service described in this document may refer to a configuration including at least one of related parameters such as a carrier interval, a CP length, and a TTI length.

It should be noted that the description of a specific network architecture in the following embodiments of the present invention is only an example (for example, LTE/LTE-A), and should not be construed as limiting. The method and apparatus disclosed by the present invention are equally applicable to a network architecture of a subsequent evolution (e.g., next generation 5G). Exemplarily, the description of each network element and interface is as follows:

Mobility Management Entity (MME)/Serving GateWay (S-GW): The MME is a key control node in the 3GPP (3rd Generation Partnership Project) LTE, belonging to the core network. The element or core network device is mainly responsible for the signaling processing part, that is, the control plane function, including access control, mobility management, attach and detach, session management function, and gateway selection. The S-GW is an important network element of the core network in the 3GPP LTE. It is mainly responsible for user plane data transmission, user plane functions such as user data forwarding and route switching, that is, routing and forwarding of data packets under the control of the MME. eNB: an eNodeB (eNB) may be a station that communicates with a user equipment UE, and may also be referred to as a base station, a Node B, an access point, and an interface. Network access equipment, etc. Each eNB can provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to such a particular geographic coverage area of an eNB and/or such a particular geographic coverage area of an eNB subsystem serving the coverage area, depending on the context in which the term is used. The eNB is mainly responsible for radio resource management, quality of service (QoS) management, data compression, and encryption on the air interface side. To the core network side, the eNB is mainly responsible for forwarding control plane signaling to the MME and forwarding user plane service data to the S-GW. The eNB may provide communication coverage for macro cells, pico cells, femto cells, and/or other types of cells. A macro cell typically covers a relatively large geographic area (e.g., a range of several kilometers in radius) and may allow unrestricted access by UEs having subscriptions to services of the network provider. A pico cell typically covers a relatively small geographic area and may allow unrestricted access by UEs having subscriptions to services of the network provider. A femto cell typically also covers a relatively small geographic area (eg, a home) and may provide restricted access (eg, a closed user group) with UEs associated with the femto cell in addition to unrestricted access. (UE in the Closed Subscriber Group, CSG), UE of the user in the home, etc.). The eNB of the macro cell may be referred to as a macro eNB. An eNB of a pico cell may be referred to as a pico eNB. And, the eNB of the femto cell may be referred to as a femto eNB or a home eNB. It should be noted that the eNB may support one or more (eg, three) cells (which are also referred to as sectors).

UE: The UE is a device that accesses the network side through the eNB in LTE, and may be, for example, a handheld terminal, a notebook computer, or other device that can access the network. When the UE needs to transmit uplink data on a specific channel (for example, physical uplink shared channel, English: Physical Uplink Shared Channel, PUSCH for short), the UE needs to inform the eNB that the uplink data needs to be transmitted, and the eNB knows that the UE needs to transmit. After the upper and lower data, uplink data scheduling is performed for the UE.

S1 interface: is a standard interface between the eNB and the core network. The eNB is connected to the MME through the S1-MME interface, and is used for control signaling transmission; the eNB is connected to the S-GW through the S1-U interface, and is used for transmission of user data. The S1-MME interface and the S1-U interface are collectively referred to as an S1 interface.

The X2 interface is a standard interface between the eNB and the eNB, and is used to implement interworking between the base stations.

Uu interface: The Uu interface is a radio interface between the UE and the base station eNB, and the UE accesses the LTE network through the Uu interface.

According to the protocol specification 3GPP TS36.331: Long Term Evolution (Long Term Evolution, LTE) The system messages between the base station and the terminal device in the air interface are divided into three categories, namely:

The first type is the Master Information Block (MIB). The MIB includes a limited number of the most important and frequent system parameters. The MIB is carried on a dedicated Physical Broadcast Channel (PBCH). Both the time domain and the frequency domain are fixed, with a period of 40 ms, and repeated transmissions during this period.

The second type: System Information Block Type 1 (SIB1), the scheduling mode of SIB1 is fixed in the time domain, with a period of 80ms, and repeats broadcasting within 80ms.

The third category: the remaining System Information Block (SIB), mainly SIB2 ~ SIB13. SIB2 to SIB13 need to be mapped to System Information (SI) for dynamic scheduling. That is, these SIB2 to SIB13 are all carried by the SI. The mapping from SIB to SI can be flexibly configured through the scheduling list (Scheduling Info-List) included in SIB1. .

SIB1 and all SIs are transmitted on a Downlink Shared Channel (DL-SCH).

It should be particularly noted that the definition of various information blocks in the above protocol specification 3GPP TS 36.331 does not only use the LTE system, but can also be used in the NR system in various embodiments of the present invention.

The embodiment of the present invention provides a blind detection method, as shown in FIG. 1 , please refer to FIG. 5 together, including:

101: After detecting the downlink working carrier of the cell, the terminal device initiates random access.

The terminal device performs downlink synchronization signal acquisition before initiating random access, thereby detecting the downlink working carrier of the cell, and if the random access is unsuccessful, the downlink synchronization signal is captured and then random access is initiated.

After receiving the random access, the system information and the configuration indication information of the downlink working carrier are received on the frequency domain channel of the downlink working carrier; the configuration indication information specifies a service type corresponding to the system information;

The foregoing configuration indication information may be in the MIB or in the SIB, which mainly depends on the size of the configuration indication information, or the information carrying capacity of the MIB and the SIB. force. The configuration indication information specifies the service type corresponding to the system information, and can be understood as the information indicating the service type corresponding to the system information by the configuration indication information, for example, whether the information of all the service types of the SIB is carried, or whether the information of one service type is carried by the SIB. As shown in FIG. 2 and FIG. 3, in FIG. 2, SI1 carries information of three service types: eMBB, URLLC, and mMTC. As shown in FIG. 3, SI1 to SI3 respectively carry eMBB, URLLC, and mMTC.

103: Obtain configuration information of the frequency domain channel of the downlink working carrier from the system information, and perform blind detection according to the configuration information and the configuration indication information.

In this embodiment, since the configuration indication information has been notified to the service type corresponding to the system information, as shown in FIG. 2 or 3, when the terminal device performs blind detection, the physical downlink control channel (Physical Downlink Control Channel, PDCCH) performs blind detection. If it is the first type in the process of blind detection, and assumes the URLLC of the service type required by the terminal device, all the service types of SI1 are detected, and the configuration information of the URLLC is found. If it is Figure 3, then you can know that the URLLC is in SI2, and only the URLLC is used for detection. There is no need to blindly check other service types.

In the embodiment of the present invention, by configuring the indication information to inform the service type corresponding to the system information of the terminal device, the delay of the number of blind detections of the terminal device can be reduced, and the NR can be adapted to include multiple service types.

Used for blind inspection.

The foregoing configuration indication information may be in the MIB or in the SIB, which mainly depends on the size of the configuration indication information, or the information carrying capacity of the MIB and the SIB. The configuration indication information specifies the service type corresponding to the system information, and can be understood as the information indicating the service type corresponding to the system information by the configuration indication information, for example, whether the information of all the service types of the SIB is carried, or whether the information of one service type is carried by the SIB. As shown in FIG. 2 and FIG. 3, in FIG. 2, SI1 carries information of three service types: eMBB, URLLC, and mMTC. As shown in FIG. 3, SI1 to SI3 respectively carry eMBB, URLLC, and mMTC.

The other is that the system information of the three service types is different on a specific subcarrier, corresponding to the situation shown in FIG.

First, as shown in Figure 6, the details are as follows:

601: The network side device selects a specific downlink working carrier for the cell, and configures system information for the downlink working carrier.

602: The network side device sends the configured system information and the configuration indication information together on the downlink carrier.

The foregoing “configuration indication information” may be an indication of all service types, or an indication of a uniform number of a numerical parameter type supported by different service types.

The specific process of configuring system information is as follows:

(1) The network side device generates a main information block according to the bandwidth of the downlink working carrier, the cell frame number, and the frequency domain channel of the downlink working carrier, for example, a Physical Hybrid-ARQ Indicator Channel (PHICH) configuration. (Master Information Block, MIB);

(2) The network side device generates SIB1 according to whether the downlink working carrier allows terminal access and system information blocks 3 to 11 of the downlink working carrier;

(3) The network side device generates SIB2 according to the radio resource configuration parameter of the downlink working carrier;

(4) The network side device configures SIB3 to SIB11 according to the cell and the entire network (the mobility of the terminal, the load of the cell, the bandwidth, the service type, and the information that the terminal device wants to acquire).

The location of the configuration instructions is as follows:

If the configuration indication information has a small number of occupied bits, the configuration indication information may be placed in the MIB. If the configuration indication information occupyes a large bit, the configuration indication information may be placed in the SIB.

603: The network side device determines whether there is a downlink working carrier that does not have system information configured.

(1) The network side device sends the main system information block on the frequency domain channel (such as PBCH, Physical Broadcast Channel, physical broadcast channel) of the downlink working carrier.

(2) The network side device sends the SIB1-SIB11 on the frequency domain channel (such as PDSCH, Physical Downlink Shared Channel, physical downlink shared channel) of the downlink working carrier, and because of the frequency domain channel (such as PDSCH, Physical Downlink) Shared Channel, downlink shared physical channel) by frequency domain channel (such as PDCCH, Physical Downlink) The control channel (physical downlink control channel) is used to indicate that the cell has a special relationship with the SI (such as SI-RNTI, System Information Radio Network Temporary Identifier, system information radio network temporary identifier). A frequency domain channel (such as a PDCCH) of a frequency domain channel (such as a PDSCH) of system information.

604: If yes, skip to 602, otherwise end.

As shown in Figure 7, the flow chart on the terminal side is as follows:

701: The terminal detects a downlink working carrier of the cell by using the downlink synchronization signal, and initiates random access. If the random access is successful, the process goes to step 702, otherwise it jumps back to step 701.

702: The terminal receives the primary system information block of the downlink working carrier on the frequency domain channel (such as the PBCH) of the downlink working carrier, and obtains the bandwidth of the downlink working carrier and the configuration information of the frequency domain channel (such as PHICH), the frame of the cell. number.

Optionally, if the configuration indication information is smaller, the terminal may obtain the configuration indication information. Otherwise, the terminal obtains the configuration indication information in the SIB. The terminal can determine, according to the detected “configuration indication information”, whether the SI transmitted on the specific carrier is an SI of all service types or an SI of a different service type.

703: The terminal performs blind detection on a frequency domain channel (such as a PDCCH) of a specific carrier in a specified frequency domain according to the configuration information of the downlink working carrier frequency domain channel (such as a PHICH, Physical Hybrid ARQ Indicator Channel) and the configuration indication information. When a frequency domain channel (such as a PDCCH) of a specific carrier is detected to have a special relationship (such as an SI-RNTI), the frequency domain channel (such as a PDSCH) corresponding to the frequency domain channel (such as a PDCCH) is parsed. ), that is, parsing system information, including the following steps:

(a) Since the transmission position of the SIB1 is fixed, the terminal first parses the SIB1 to obtain information on whether to allow the terminal to access the downlink working carrier and the downlink working carrier and other system information block scheduling information.

If terminal access is not allowed, the terminal proceeds to step 701; otherwise, it proceeds to the following step (b).

(b) The terminal acquires other SIB1s according to other system information block scheduling information on the SIB1 and obtains corresponding SIs.

704: The terminal determines whether it is required to acquire the SI of the other downlink working carrier.

The system information of the terminal to determine whether it needs to obtain other downlink working carriers includes the following two types. Any of the situations:

When the terminal determines that it is necessary to acquire the SI of the other downlink working carrier, go to step 701 to repeat the process of synchronization, interception, and parsing;

When the terminal determines that it is not necessary to acquire the SI of the other downlink working carrier, the process ends.

Second, you can still refer to the example shown in 6, as follows:

Step 1: The network side device selects a specific downlink working carrier for the cell, and configures system information for the downlink working carrier.

Step 2: The network side device sends the configured system information and the configuration indication information together on the downlink carrier.

The foregoing “configuration indication information” may be an indication of a number of different service types, or an indication of a different numerical parameter (numerology) type, or an indication of a different subframe configuration.

The specific process of configuring system information is as follows:

The location of the configuration instructions is as follows:

(1) The network side device transmits the main system information block on the PBCH (Physical Broadcast Channel) of the downlink working carrier.

(2) The network side device sends the SIB1-SIB11 on the frequency domain channel (such as PDSCH, Physical Downlink Shared Channel, physical downlink shared channel) of the downlink working carrier, and the frequency domain channel (such as PDSCH) is frequency-transmitted. Domain channel (PDCCH) to indicate, Therefore, the indication that the cell has a special relationship with the SI (such as SI-RNTI) is carried on a frequency domain channel (such as a PDCCH) for indicating a frequency domain channel (such as a PDSCH) carrying system information.

604: If yes, skip to 601, otherwise end.

At the same time, if the configuration indicator information is small, the terminal can also obtain the configuration indication information. Otherwise, the terminal obtains the configuration indication information in the SIB. The terminal can determine, according to the detected “configuration indication information”, whether the SI transmitted on the specific carrier is an SI of all service types or an SI of a different service type.

703: The terminal performs blind detection on a frequency domain channel (such as a PDCCH) of a specific carrier in a specified frequency domain according to the configuration information of the downlink working carrier frequency domain channel (such as PHICH) and the “configuration indication information”, and the schematic diagram is as follows: Shown. When a frequency domain channel (such as a PDCCH) of a specific carrier is detected to have a special relationship (such as an SI-RNTI), the frequency domain channel (such as a PDSCH) corresponding to the frequency domain channel (such as a PDCCH) is parsed. ), that is, parsing system information, including the following steps:

(a) Since the sending position of the SIB1 is fixed, the terminal first parses the SIB1 to obtain information on whether to allow the terminal to access the downlink working carrier and other system information block scheduling information of the downlink working carrier.

The system information that the terminal determines whether it needs to obtain other downlink working carriers specifically includes any one of the following two situations:
