Description

Method, device and receiving method, device and terminal for transmitting system message

Technical field

The present disclosure relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, and a receiving method, apparatus, and terminal for transmitting a system message.

Background technique

After a few decades of development, cellular mobile communication technology has entered the era of 4G (fourth generation mobile communication technology), and in order to meet the higher, faster and newer communication needs in the future, the industry has begun to develop the future 5G (the first Five-generation mobile communication technology) research. 5G will conduct further technical research on greater throughput, more user connections, lower latency, higher reliability, lower power consumption, including network-side devices and user terminals. At present, the industry has proposed 5G technology goals: to achieve 1000 times mobile data traffic growth per region by 2020, 10 to 100 times throughput per user equipment (UE, User Equipment), 10 to 100 times the number of connected devices The growth of low-power devices has 10 times longer battery life and a 5x end-to-end delay.

Among them, in order to reduce the power consumption of system equipment and provide radio resource utilization, the system information (SI, System Information) propagation mechanism widely used in 2G (GSM), 3G (WCDMA & TS-SCDMA) and 4G (LTE) is implemented. the study. In 2G, 3G and 4G mobile communication systems, the transmission mechanism of system information is generally similar, but there are some differences in details; the common features are:

Each cell transmits complete system information in a broadcast manner;

System information is divided into multiple system information blocks (SIB) according to features and functions;

From the perspective of the configuration of information such as resources and control parameters used for broadcasting, there are usually three methods: fixed configuration (predefined), pre-configuration, and dynamic allocation. The fixed configuration (predefined) usually refers to the system clearly defining configuration information of related resources and control parameters through some form (such as standard specification); dynamic scheduling generally refers to the configuration information of related resources and control parameters dynamically sent to the receiving through the physical layer channel. The relevant configuration information is valid only in the time range defined by the dynamic scheduling; the pre-configuration usually means that the related resources and control parameters are configurable, and the configuration information is sent to the receiver through the layer 2 and layer 3 messages, as long as The sender does not update and the relevant configuration information is always valid. The configuration information in the pre-configuration mode is usually called scheduling information. In 3G and 4G systems, the resources and control parameters related to the Main Information Block (MIB) are fixed (predefined) configuration mode, SIB1 in 4G. The related resources and control parameters are combined by fixed and dynamic allocation. All other SIB-related resources and control parameters in 3G and 4G are pre-configured in whole or in part. The configuration information of these SIBs in pre-configured mode is used. Both include scheduling information, in which 3G scheduling information is sent through the MIB or a dedicated SB (scheduling block), and 4G scheduling information is sent through SIB1.

The scheduling information includes resources and control information related to each SIB broadcast, such as a time point (or window) and a transmission period, etc., in the time domain, and each SIB will be periodically broadcasted periodically according to the scheduling information. ;

From the perspective of UE usage, the effective range of almost all system information is limited to the cell it transmits, that is, when the UE moves from one cell and reselects to another cell, it needs to completely receive the new cell in the new cell. System information sent.

Under the above system information transmission mechanism, with the continuous introduction of new technologies, the number of transmission blocks is increasing, the content of system information is continuously increasing, and the resources consumed are increasing. Moreover, many of the transport blocks for a particular new technology are actually limited in demand, and continuous broadcast transmission results in wasted resources and increased power consumption of network-side devices.

detailed description

The present disclosure will be further described in detail below in conjunction with the drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the disclosure and are not intended to be limiting.

In the following embodiments, with reference to the prior art concepts and conveniences in the background art, the following concepts are used: the minimum system information is the first system information, the other system information is the second system information, and the main information block MIB is the third system information. The remaining minimum system information is the fourth system information.

In view of the above problems, the embodiment of the present disclosure discloses a new system information transmission method, and the main technical contents are as follows:

As shown in Figure 1, the system information is divided into two categories according to the importance of the information:

One type is the necessary system information. This patent is called Minimum System Information (Minimum SI) and is still transmitted by broadcast mechanism. Minimum SI usually includes related key parameters related to cell selection and initial access (including acquisition of Other SI). System information, which needs to be transmitted by means of periodic broadcast, so that the information that needs to be broadcasted is greatly compressed.

The other category is all system information except the minimum system message. This patent is called Other System Information. The other system information is transmitted according to the requirements of the user equipment (UE) or the network side base station equipment (such as the Node B), and may be transmitted by using dedicated signaling, broadcast, or multicast. Rather than continuously transmitting periodically to improve resource utilization efficiency.

For the above two types of system information, a structure in which a plurality of system information blocks SIB are divided by features and/or functions is still used.

The Minimum SI can be divided into the MIB and the remaining Minimum SI; the MIB, the remaining Minimum SI and the Other SI are respectively transmitted through different broadcast channels, the MIB is transmitted through the first broadcast channel, and the remaining Minimum SI is transmitted through the second broadcast channel, Other SI passes the The three broadcast channels are transmitted; wherein the first, second, and third broadcast channels may be physical channels having the same name but different resources such as the time domain, the frequency domain, and/or the code domain.

The scheduling information of the SIB broadcasted by the other SI on the third broadcast channel is broadcasted on the second broadcast channel by the remaining Minimum SI; that is, the physical channel, the broadcast time, and the like used by the SIB in the Other SI to be transmitted are related to the transmission. The information is broadcast on the second broadcast channel.

Whether the broadcast indication information of any SIB in the other SI broadcast on the third broadcast channel is broadcast on the first broadcast channel through the MIB.

In addition, the scheduling information in the remaining Minimum SI includes one or more configuration information for transmitting the SIB; when there is multiple configuration information, the MIB also includes scheduling information index information of Other SI, which is used to indicate that the cell is being used. Other SI scheduling information.

For the broadcast transmission mode, as shown in Figure 2, the broadcast transmission mechanism of Other SI is as follows:

The concept of the SI window is similar to that of LTE. That is, some periodic SI windows are predefined in the form of scheduling information, and SIBs of Other SI will be broadcast in these SI windows. The SI window includes a transmission window and a window period, and is a period of time defined by a time and/or a radio frame, and a time domain concept such as a subframe or a time slot; wherein the setting of the transmission window includes a starting point and a window length, or a starting point. And the end point, the window period includes the period length.

In the following embodiments of the present patent, the MIB is an independent system information block, and the remaining Minimum SI includes two information blocks SIB1 and SIB2 and one common information block, and the Other SI includes SIB3/4/5/6/7. 5 information blocks. The scheduling information of Other SI may be configured in the range of 1 to 2, where the first configuration includes only one SI window, and all SIBs of SIB3/4/5/6/7 are mapped to the same SI window; The second configuration includes two SI windows, where SIB3/4 is mapped to SI window 1, and SIB5/6/7 is mapped to SI window2. Correspondingly, the Other SI scheduling information index field is optionally included in the MIB to indicate a valid Other SI scheduling information configuration option used by a cell.

It should be noted that the transmission method of the system message in this patent is also applicable to the transmission of multicast messages. In addition, only two configuration examples are given in this patent embodiment, just to illustrate the patent scheme, but it is not limited to the above two examples, and one, two or more SI windows may be configured.

Example 1

As shown in FIG. 3, in the case of network deployment of an independent cell, all system information is broadcast by the cell itself, including: the MIB is sent through the first broadcast channel, and the remaining Minimum SI is sent through the second broadcast channel, and Other SI passes. The third broadcast channel is transmitted, the first and third broadcast channels are indicated by dotted lines, and the second broadcast channel is indicated by a broken line.

The SIB1/SIB2 has only one configuration. In this case, the related fields such as the SI index and the SI index value are not required. Other SI scheduling information configuration only configures the first configuration, that is, only one SI window, SIB3/4/5/6/7 (all SIBs) are mapped to the same SI window; at this time, there is only one configuration , Other SI scheduling information index field in MIB will not be needed.

As shown in FIG. 3, for the independent cell, a method for transmitting a system message includes:

Transmitting the MIB and the remaining Minimum SI through the first broadcast channel and the second broadcast channel, where the MIB includes the broadcast indication information of the Other SI; the Minimum SI includes the scheduling information of the Other SI;

In one embodiment: if (SI) is requested by the (user terminal) to transmit certain SIBs in Other SI, and it is determined to be transmitted by means of broadcast, as shown in FIG. 6, when it is required to transmit SIB3 and SIB5, then other SI in the MIB is set. The indication bit corresponding to SIB3 and SIB5 in the broadcast indication information is 1, and is sent through the first broadcast channel;

According to the scheduling information of Other SI, SIB3 and SIB5 are transmitted through the third broadcast channel in the corresponding SI window.

Receiving system messages for UEs residing on the cell, including:

Receiving MIB information of the cell by using the first broadcast channel of the camping cell;

The remaining Minimum SI information received through the second broadcast channel of the camped cell, including the Other SI scheduling information described above.

The process when the UE needs to detect whether certain SIs of other SI are broadcasting and receiving these SIBs is:

For the terminal that requests the base station to send the system message, according to the scheduling information of Other SI and the SIB of the other SI that it needs, it directly detects and receives through the third broadcast channel in the corresponding SI window.

For other terminals, receiving the MIB on the first broadcast channel, checking whether the indication bit corresponding to the SIB in the Other SI broadcast indication information is 1; if not, sending a request for broadcasting the system message; if yes, according to The other SI scheduling information and the SIB of the Other SI required by it are received through the third broadcast channel in the corresponding SI window.

The broadcast indication information of the Other SI may be in the form of a bitmap (bitmap). As shown in FIG. 6, if a certain SIB is being broadcast, the broadcast indication bit corresponding to the SIB is set to 1, and FIG. 6 shows the SIB3 and SIB5 is broadcasting.

In this embodiment, the SIBs of all Other SIs are mapped to the same SI window, so that SIB3 and SIB5 can be received through the third broadcast channel according to the configuration information of the SI window.

As long as the SI window configuration information does not change, the UE does not need to receive the scheduling information of Other SI in the remaining Minimum SI, and can receive the broadcasted Other SI.

Example 2

As shown in FIG. 4, in the case of network deployment in which multiple co-frequency cells are cascaded, each of the cells transmits MIB and Other SI through respective first/third broadcast channels, and several of them are selected (gray in the figure) The cell in which the base station is located transmits the common remaining Minimum SI in the SFN (Single Frequency Network) mode, including the configuration information of the two groups of SIB1/SIB2, and the Other SI scheduling information includes the configuration of 2: the first type: 1 SI window, all SIBs in SIB3/4/5/6/7 are mapped to the same SI window; second: 2 SI windows, where SIB3/4 is mapped to SI window 1, SIB5/6/7 is mapped to SI window 2.

In order to implement SFN mode broadcast, all base stations used for SFN transmission must send the same remaining Minimum SI. Therefore, the above-mentioned common remaining Minimum SI needs to be sent to all cells used for SFN transmission, as shown in the gray base station in FIG. The cell, or all base stations used for SFN transmission, are configured with the same common remaining Minimum SI.

In a plurality of co-frequency cells, at different times, different cells may need to send different SIBs in Other SI, and may need to select different Other SI scheduling information configurations. As shown in FIG. 4, the cell M selects The first type of Other SI scheduling information is configured, and the cell N selects the second Other SI scheduling information configuration. Therefore, in addition to broadcasting the Other SI broadcast indication information, the MIB on the first broadcast channel of each cell needs to broadcast the selected Other SI scheduling information index information.

As shown in FIG. 4, for a base station on the network side (which may include multiple base stations), the method for transmitting system messages includes:

The respective MIBs are sent by the first broadcast channel of each cell, including the Other SI scheduling information index selected by the cell, for example, the cell M in FIG. 4 selects and sets the first type of Other SI scheduling information index, and the cell N selects and Set the above second Other SI scheduling information index.

Configuring a common remaining Minimum SI, selecting multiple cells, such as the cell where the gray base station is located in FIG. 4, synchronizing the common remaining Minimum SI among the multiple cells (ie, keeping the content the same), and adopting the SFN method in the selected multiple The common remaining Minimum SI is transmitted on the second broadcast channel in the cells, including the scheduling information of the Other SI described above.

If a cell, such as cell M and cell N in FIG. 4, is requested by the (user terminal) to transmit certain SIBs of Other SI, and it is determined to be transmitted by broadcast, as shown in FIG. 6, it is required to transmit SIB3 and SIB5. Then, the cell M and the cell N respectively set the indication bits corresponding to SIB3 and SIB5 in the Other SI broadcast indication information in the respective MIBs to 1, and respectively transmit them through the respective first broadcast channels.

Each cell transmits SIB3 and SIB5 through respective third broadcast channels in the corresponding SI window according to the respective selected Other SI scheduling information and the SIB of the Other SI transmitted by the broadcast. For example, in cell M, SIB3 and SIB5 are transmitted in a unique SI window. In cell N, SIB3 is transmitted in SI window 1, and SIB5 is transmitted in SI window 2.

For UEs residing on a certain cell, receiving system messages includes:

Receiving MIB information of the cell by using the first broadcast channel of the camping cell, where the Other SI scheduling information index is included;

The common remaining Minimum SI is received in the SFN manner through the second broadcast channel, including Other SI scheduling information.

When the UE needs to detect whether the SIBs in some Other SIs are broadcasting and receiving these SIBs, the process is:

For the terminal that requests the base station to send the system message in the camping cell, according to the scheduling information of Other SI and the SIB of the other SI, it is directly detected and received by the third broadcast channel in the corresponding SI window.

or,

For other terminals in the camped cell, the MIB on the first broadcast channel is received, and the indicator bit corresponding to the SIB in the Other SI broadcast indication information is checked, and if not, the base station is requested to deliver the request. System message; if yes, determining Other SI scheduling information selected by the cell according to the Other SI scheduling information index;

According to the Other SI scheduling information selected by the cell and the SIB of the Other SI required by the cell, the resident SI receives the Other SI through the third broadcast channel in the corresponding SI window.

The Other SI broadcast indication information may be indicated by a bitmap. As shown in FIG. 6, if a certain SIB is being broadcast, the broadcast indication bit corresponding to the SIB is set to 1, and FIG. 6 shows that SIB3 and SIB5 are being broadcast.

In this embodiment, as shown in FIG. 4, in the cell M, the UE receives the SIB3 and the SIB5 in the unique SI window; in the cell N, the UE receives the SIB3 in the SI window 1, and receives the SIB5 in the SI window 2. .

Similarly, since a certain cell can select one type of use according to the configured scheduling information of multiple Other SIs, and the change of the SIB included in the broadcasted Other SI does not affect the change of the scheduling information of Other SI in the remaining Minimum SI, The remaining Minimum SI is relatively stable, so that the SFN technology is used to transmit the remaining Minimum SI through the second broadcast channel. For the UE, the UE does not need to receive the remaining Minimum SI as long as the configured scheduling information of the multiple Others does not change. In the scheduling information of Other SI, the different Other SIs that receive the broadcast can be realized.

Example 3

As shown in FIG. 5, in the case of network deployment in which the same frequency/inter-frequency cell overlaps coverage, each of the cells transmits the MIB and Other SI through the respective first/third broadcast channels; and the public residual is transmitted in the macro cell. Minimum SI, including 2 sets of SIB1/SIB2 configuration information, Other SI scheduling information includes 2 configurations: first, 1 SI window, SIB3/4/5/6/7 all SIBs are mapped to the same SI window Second; 2, SI window, where SIB3/4 is mapped to SI window 1, SIB5/6/7 is mapped to SI window 2.

In a plurality of cells, at different times, different cells may need to send different SIBs in Other SI, and may need to select different Other SI scheduling information configurations, as shown in FIG. 5, the small cell 2 selects the first One Other SI scheduling information configuration, and the small cell 3 selects the second Other SI scheduling information configuration. Therefore, in addition to broadcasting the Other SI broadcast indication information, the MIB on the first broadcast channel of each cell needs to broadcast the selected Other SI scheduling information index information.

As shown in FIG. 5, for a base station on the network side (which may include multiple base stations), the system message sending method includes:

The respective MIBs are sent by the first broadcast channel of each cell, including the Other SI scheduling information index selected by the cell, for example, the small cell 2 in FIG. 5 selects and sets the first type of Other SI scheduling information index, and the small cell 3 Selecting and setting the second Other SI scheduling information index;

Configuring a common remaining Minimum SI, and transmitting a common remaining Minimum SI through the second broadcast channel in the macro cell 1, including the foregoing Other SI scheduling information;

If a certain cell, such as small cell 2 and small cell 3 of FIG. 5, is requested to transmit certain SIBs of Other SI and determine broadcast transmission, as shown in FIG. 6, when it is required to transmit SIB3 and SIB5, respectively set respective MIBs. The indication bits corresponding to SIB3 and SIB5 in the other SI broadcast indication information are 1, and are respectively sent through respective first broadcast channels;

Each cell transmits SIB3 and SIB5 through respective third broadcast channels in the corresponding SI window according to the respective selected Other SI scheduling information and the SIB of the Other SI transmitted by the broadcast. For example, in small cell 2, SIB3 and SIB5 are transmitted in a unique SI window, and in small cell 3, SIB3 is transmitted in SI window 1, and SIB5 is transmitted in SI window 2.

For UEs residing on a certain cell, receiving system messages includes:

The common remaining Minimum SI received through the second broadcast channel of the macro cell 1, including Other SI scheduling information.

Then, when the UE needs to detect whether certain SIs of other SI are broadcasting and receiving these SIBs, the process is:

or,

For other terminals in the camped cell, the MIB on the first broadcast channel is received, and the indicator bit corresponding to the SIB in the Other SI broadcast indication information is checked, and if not, the cell is requested to send the required system. a message; if yes, determining Other SI scheduling information selected by the cell according to the Other SI scheduling information index;

In this embodiment, as shown in FIG. 5, in the small cell 2, the UE receives the SIB3 and the SIB5 in the unique SI window; in the small cell 3, the UE receives the SIB3 in the SI window 1, in the SI window 2 Receive SIB5.

Similarly, since a small cell can select one type of use according to the configured scheduling information of multiple Other SIs, and the change of the SIB included in the broadcasted Other SI does not affect the change of the scheduling information of Other SI in the remaining Minimum SI. Therefore, the remaining Minimum SI is relatively stable, so that the common remaining Minimum SI is transmitted through the second broadcast channel of the macro cell 1. For the UE, the UE does not need to go to the macro as long as the scheduling information of the configured multiple SIs does not change. The cell 1 receives the scheduling information of Other SI in the remaining Minimum SI, and can implement different Other SIs that receive the broadcast.

In the above three embodiments, if the broadcast indication information that is being broadcast by a certain SIB in Other SI is also broadcasted through the remaining Minimum SI, when the SIB combination of the Other SI broadcast changes, the change of the remaining Minimum SI is caused; Similarly, if the Other SI scheduling information can be changed without the mechanisms of the multiple Other SI scheduling information configuration in this patent and the Other SI scheduling information index in the MIB, when a cell changes the Other SI scheduling information, it will cause the remaining Minimum SI changes. In the scenario shown in FIG. 4, in the SFN technology, the remaining Minimum SIs of multiple nodes need to be consistent and synchronized. Therefore, when the remaining Minimum SI of a cell changes, the network side needs to adopt a complex synchronization mechanism. The remaining Minimum SI content between multiple nodes of the packet is synchronized, which can cause a large amount of signaling overhead. In the scenario shown in FIG. 5, the UE camping on the small cell is required to go to the second broadcast channel of the macro cell to read the changed remaining Minimum SI, and then return to the small cell to read Other SI on the third broadcast channel. This will cause the UE to perform additional cell reselection procedures, thereby increasing the power consumption of the UE.

Example 4

An important development direction of 5G mobile communication systems is to use large bandwidth high frequency spectrum to carry large amounts of traffic. Considering that the path loss increases with the increase of the frequency when the wireless signal propagates, the coverage of the high-frequency mobile communication technology becomes a fatal problem, that is, if the omnidirectional transmission method is the same as the low frequency, the transmission power is high. Frequency systems often cover only a small area. To overcome this problem, directional transmission techniques using beam forming techniques will be used to perform high frequency wireless signal transmission. The beamforming technology can extend the signal coverage in the longitudinal direction of the radius, but the coverage in the horizontal direction is greatly reduced. Moreover, the number of beams that the network side device base station can simultaneously transmit is often limited, and therefore, for broadcast or multicast. The signal is transmitted while beam sweeping technology is introduced to meet the requirements of lateral signal coverage. Beam scanning techniques can be implemented using time domain and/or frequency domain based methods. As shown in FIG. 7, the concept of a sweeping block is introduced in the time domain. A beam transmitted in one scanning block can cover only a part of cells, and multiple scanning blocks are used to cover the entire cell. The multiple scanning blocks are called It is a sweeping burst.

In the above three embodiments, if the MIB and Other SI broadcasts are both beam scanning technologies, and the beam scanning configuration information of the MIB can be used to uniquely determine the beam scanning configuration information of Other SI, the beam scanning configuration information of Other SI and The beam scanning configuration information of the MIB is the same; the beam scanning configuration information is used to configure the scanning block and the scanning array, and the beam scanning configuration information includes at least: the number of scanning blocks included in one scanning array and/or the identification information of the scanning block, and/ Or the number of beams and/or beam identification information included in one scan block. The SIB broadcast indication information of the same or different Other SI may be broadcasted in each scan block of the MIB. In an embodiment, if the SIB broadcast indication information of the same Other SI is broadcast in each scan block when the MIB broadcast is transmitted, the SIB of the same Other SI is broadcast in each scan block when the Other SI broadcast is transmitted; if the MIB broadcasts When SIB broadcast indication information of different Other SIs is broadcast in each scan block at the time of transmission, the SIBs of different Other SIs are broadcast correspondingly in each scan block when the Other SI broadcasts.

As shown in FIG. 8, the system message is sent to the base station on the network side, including:

Transmitting the MIB and the remaining Minimum SI through the first broadcast channel and the second broadcast channel, where the remaining Minimum SI includes scheduling information of Other SI; at the same time, determining to adopt a beam scanning technology when transmitting the MIB, and determining beam scanning configuration information; In an embodiment, it is determined that the beam scanning technology is also used when transmitting the Other SI, and the beam scanning configuration information sent by the Other SI is determined based on the beam scanning configuration information sent by the MIB, and the information is broadcasted implicitly or explicitly, such as an implicit method. The system pre-defines the two, and the display method includes including relevant configuration information in the remaining Minimum SI. This embodiment will be described in the same way that the beam scanning configuration information of the MIB and Other SI is implicitly configured.

At the same time of a cell, if different UEs request different SIBs of different SIs, the different Other SI broadcast indication information is set in the MIB corresponding to the different scanning blocks and is in the first Broadcast channel transmission, for example, UE1 and UE2 request SIB3 and SIB5 of Other SI in scan block SB#1; UE3 and UE4 request SIB4 and SIB6 of Other SI in scan block SB#n; UE5 requests in scan block SB#M Other SI's SIB7. Then, at the time of MIB beam scanning transmission, SIB3 and SIB5 which broadcast the transmission indication Other SI are being broadcasted in the scanning block SB#1; SIB4 and SIB6 which broadcast the transmission indication Other SI are being broadcasted in the scanning block SB#n; in the scanning block SB#M The broadcast transmission indicates that the SIB7 of Other SI is broadcasting.

Correspondingly, according to the scheduling information of Other SI, the SIBs of different Other SIs are corresponding to different scanning blocks, and are transmitted on the third broadcast channel. Illustratively, at the time of Other SI beam scanning transmission, only SIB3 and SIB5 are broadcasted and transmitted in scanning block SB#1; SIB4 and SIB6 are only broadcasted in scanning block SB#n; SIB7 is only broadcasted in scanning block SB#M.

For UEs residing on this cell, receiving system messages includes:

The MIB information and the remaining Minimum SI information of the cell are received by the first broadcast channel and the second broadcast channel of the cell, including Other SI scheduling information, beam scanning configuration information of the MIB, and beam scanning configuration information of Other SI.

Receiving, at the location where the UE is located, the MIB of the corresponding scan block on the first broadcast channel, checking that the Other SI broadcast indication information indicates which SIBs are being broadcasted; for example, UE1 and UE2 receive the Other SI in the MIB of the scan block SB#1 Broadcast indication information being broadcast by SIB3 and SIB5; UE3 and UE4 receive broadcast indication information that SIB4 and SIB6 of Other SI are broadcasting at the MIB of scan block SB#n; UE5 receives Other SI at MIB of scan block SB#M The broadcast indication information that SIB7 is broadcasting.

Correspondingly, according to the scheduling information of Other SI, UE1 and UE2 receive SIB3 and SIB5 of Other SI in Other SI of scanning block SB#1; UE3 and UE4 receive SIB4 and SIB6 of Other SI in Other SI of scanning block SB#n; The UE 5 receives the SIB7 of Other SI at the Other SI of the scan block SB#M.
