Description

System information transmission, processing method and device

Technical field

The present disclosure relates to the field of communications, for example, to a method and apparatus for transmitting and processing system information.

Background technique

Cellular mobile communication technology has entered the 4G era after only a few decades of development, and in order to meet the higher, faster and newer communication needs, the industry has begun to research the future 5G technology. 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 5G technology target is expected to achieve 1000 times of mobile data traffic growth per region. Each user equipment (User Equipment, UE for short) has a throughput increase of 10 to 100 times, and the number of connected devices increases by 10 to 100 times. The device has 10 times longer battery life and a 5x end-to-end delay.

In order to reduce the power consumption of system equipment and provide radio resource utilization, it is already in 3G (Wideband Code Division Multiple Access (WCDMA) & Time Division Synchronous Code Division Multiple Access (Time Division- The system information dissemination mechanism widely used in Synchronized Code Division Multiple Access (TD-SCDMA) and 4G (Long-Term Evolution (LTE)) has been studied. In 3G and 4G mobile communication systems, the transmission mechanism of system information is generally similar, but differs in details; its common features are: each cell transmits complete system information in a broadcast manner. The system information is divided into multiple system information blocks (SIBs) according to features and functions. From the perspective of the configuration of information such as resources and control parameters used for broadcasting, fixed (predefined), pre-configured And dynamic allocation of 3 ways. Among them, fixed (predefined) usually refers to the system clearly defines the configuration information of related resources and control parameters by some form (such as standard specification). Dynamic scheduling usually means that the configuration information of related resources and control parameters is dynamically sent to the receiver through the physical layer channel, and the relevant configuration information is valid only in the time range defined by the dynamic scheduling. Pre-configuration usually means that the relevant resources and control parameters are configurable, and the configuration information is sent to the receiver in the form of Layer 2 and Layer 3 messages. The relevant configuration information is always valid as long as the sender does not update. 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, 4G. The SIB-related resources and control parameters in the combination are fixed and dynamic allocation. The other SIB-related resources and control parameters in 3G and 4G are all or partially pre-configured. These SIB-related pre-configuration methods are adopted. The configuration information includes scheduling information, where 3G scheduling information is sent through the MIB or a dedicated Scheduling Block (SB), and 4G scheduling information is sent through SIB1.

The foregoing scheduling information includes resources and control information related to each SIB broadcast, for example, in the time domain, including a time point (or window) and a sending period of the sending, each SIB will be continuously and periodically periodically according to the scheduling information. Broadcast transmission. From the perspective of UE usage, the effective range of almost all system information is limited to the transmitted cell, 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 transmission blocks for specific new technologies are actually limited in demand, and continuous broadcast of system information of new cells may result in waste of resources and increase power consumption of network-side devices.

detailed description

Embodiments of the present application will be described in detail below with reference to the drawings in conjunction with the embodiments. The embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

The terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not intended to describe a particular order or order.

In view of the above problems, the related art proposes to divide system information into two categories according to the importance degree of information. One type is necessary system information, which is called minimum system information (Minimum SI), and still uses broadcast mechanism to transmit; another type All other system information, including other system information (Other SI), is referred to herein as on-demand and transmitted using dedicated signalling or broadcast or multicast mechanisms. For these two types of system information, similar structures that are divided into multiple system information blocks SIB by feature and/or function are still used; Minimum SI usually includes related critical systems such as cell selection and initial access (including acquisition of Other SI). Information, which is transmitted by means of periodic broadcast, so that the information that needs to be broadcasted is greatly compressed; Other SI is transmitted according to the needs of the user equipment or the network side base station (such as the evolved node, referred to as BNode B). Transmission is performed by dedicated signalling or broadcast or multicast instead of continuous periodic transmission to improve resource utilization efficiency. For other SI broadcast transmission methods, Figure 1 is related. Schematic diagram of the broadcast transmission mechanism of Other SI in the technology, as shown in Figure 1, the basic concepts include:

Based on the SI window, the concept of the SI window is similar to Long Term Evolution (LTE). That is, some periodic SI windows are predefined in the time domain in the scheduling information, and the 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 time and/or a time domain concept such as a radio frame, a subframe, or a time slot. The setting of the sending window includes a starting point and a window length, or a starting point and a ending point, and the window period includes a period length.

Other SI related scheduling information will be sent in Minimum SI, which may also include the mapping between SIB and SI window of Other SI. Minimum SI can also be divided into two parts, such as a part of the MIB in 3G and 4G systems, which are transmitted with fixed resources and control parameters, while other SIBs can be sent in whole or in part with pre-configured resources and control parameters. The relevant scheduling information can be sent in the MIB. In this case, the Other SI related scheduling information will be sent in the other SIBs in the Minimum SI.

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. 2 is a schematic diagram of a scanning array in the related art. As shown in FIG. 2, a concept of a sweeping block (SB) is introduced in a time domain, and 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 scan blocks are called sweeping bursts.

However, beam scanning technology imposes great limitations on the use of resources. For example, because the sweeping of a broadcast channel needs to transmit a beam in a certain direction, although the broadcast channel uses only a small amount of frequency domain resources, other frequency domain resources. It is also restricted to use only in this direction, which will greatly affect the efficiency of the use of spectrum resources, so the beam scanning technology should be used as little as possible to minimize the broadcast transmission of system information. For system information transmitted on demand broadcast, such as the Other SI described above, in order to reduce the broadcast transmission of system information, it can be realized by reducing the demand.

However, when the above system information is broadcasted, the resources for transmitting system information and the energy consumption of the base station device are still relatively large.

The method embodiments provided by the embodiments of the present application may be implemented in a mobile terminal, a computer terminal, or the like.

A variety of functional applications and data processing, that is, to achieve the above method. Memory 304 can include high speed random access memory and can also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid state memory. In some examples, memory 304 can include memory remotely located relative to processor 302, which can be connected to mobile terminal 30 over a network. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The above-described network specific example may include a wireless network provided by a communication provider of the mobile terminal 30. In one example, the transmission device 306 includes a Network Interface Controller (NIC) that can be connected to other network devices through a base station to communicate with the Internet.

The following is an example of the application.

Specific embodiment 1:

On the network side, there is a logical or physical management entity, such as a base station or a network management entity, to manage system information related to multiple cells (cells) or other logical coverage areas or physical coverage areas, including generation, modification, and deletion. For the maintenance operation, the following describes a cell as an example. One of the functions of the management entity is to make the system information blocks sent by all cells in the effective area of one system information block the same, including the same effective area range and version information.

The information of the effective area range may be a Public Land Mobile Network Identity (PLMN ID), a Cell ID, and a Transmission Receive Point Identity (TRP ID). And other defined area identification IDs associated with geographic or logical areas. Wherein, if an area A includes a plurality of areas B, when the information of the effective area range uses the area A, all the areas B belonging to the area A belong to the effective area range. For example, the information of the effective area range of a certain SIB is a PLMN ID. Since one PLMN may include several cells, the SIB is valid in all cells belonging to the PLMN ID.

FIG. 6 is a schematic diagram of network deployment in the embodiment. As shown in FIG. 6 , in a network deployment scenario in which multiple cells are cascaded, each cell sends system information that is to be applied to all or part of the cell. The cell 1/2/3/4 is configured with the same SIBm, including the effective area range and version information, wherein the information of the effective area range is PLMN A, and the cells 1/2/3/4 belong to PLMN A, which is related to the version information. The value tag value is 5. Cell 5/6/7 uses another SIBm with the same configuration, including information of the effective area range and version information, where the information of the effective area range is PLMN B, and is defined as a cell in the form of a cell ID list. 5/6/7, the value tag value associated with the version information is 8.

Optionally, the cell periodically broadcasts, by using the second broadcast channel, a value tag value related to the system information block identifier currently used by the current cell and/or the version information of the system information block. The cell-related identification information, such as the PLMN ID, the cell ID, and the like to which the cell belongs, is periodically broadcasted through the first or second broadcast channel. The corresponding system information block is transmitted periodically or on demand through the second broadcast channel or the third broadcast channel. The system information block includes information of a valid area range, and optionally, a value tag value related to the version information.

7 is a schematic diagram of a broadcast channel in this embodiment. As shown in FIG. 7, when transmitting on the network side, the value tag value related to the SIBm version information is broadcasted in SIB1 through the second broadcast channel (ie, broadcast channel 2). At the same time, the SIBm including the information of the effective area range is broadcasted on demand by the third broadcast channel (ie, the broadcast channel 3) as part of the Other SI, and may also include the value tag value associated with the version information of the SIBm.

Correspondingly, on the UE side: when the UE selects a cell and successfully receives the system information block from the cell, the received system information block is used and saved. As shown in FIG. 6, UE1 selects to camp on cell 3, and receives and saves a plurality of system information blocks and valid area range and version information of the system information blocks from cell 3, including SIBm information blocks, and effective area ranges thereof. Configured as PLMNA with a value tag of 5. UE2 selects to camp on cell 6, receives and saves a plurality of system information blocks from cell 6 and information and version information of valid area ranges of these system information blocks, including SIBm information blocks, whose effective area range is configured as PLMN A cell ID list in B, including cell 5/6/7, and a value tag value of 8.

When the UE moves and reselects to another cell, the UE will first receive part of the system information, and obtain identification information related to the cell, such as a PLMN ID, a cell ID, etc., related to the system information block identifier and its version information currently used by the cell. Value tag. As shown in FIG. 6 and FIG. 7, when UE1 and UE2 are respectively moved from cell 3 and cell 6 and reselected to cell 4, the identification information of cell 4 is first obtained through the first broadcast channel and/or the second broadcast channel: PLMN A And the cell 4, at the same time, obtains the system information block identifier and the value tag value related to the version information, which includes the SIBm, and the value tag is 5, by using the SIB1 on the second broadcast channel. The UE compares the identification information of the new cell (cell4) (corresponding to the predetermined cell, for example, cell3, cell6) and the information of the valid area range of the saved system information block, determines whether the system information block is valid in the new cell, and determines the new cell at the same time. Whether the version information of the system information block is the same as the version information of the saved system information block. When the new cell identifier belongs to the effective area of the system information, and the version information of the system information block of the new cell is the same as the version information of the saved system information block, the UE will continue to use the saved system information block in the new cell; The saved cell information block is not used when the cell identity does not belong to the effective area of the system information, and/or the version information of the system information block of the new cell is different from the version information of the saved system information block. Optionally, when the new cell identifier belongs to the effective area range of the system information, and the version information of the system information block of the new cell is the same as the version information of the saved system information block, the new cell is not requested and/or received. The system information block; when the version information of the system information block of the new cell is different from the version information of the saved system information block, the system information block sent by the cell is requested and/or received in the new cell. As shown in FIG. 6, when UE1 and UE2 are respectively moved from cell 3 and cell 6 and reselected to cell 4, UE1 determines that cell 4 belongs to PLMN A, and cell 4 is within the valid area of the SIBm that it holds, and that the cell is currently The value tag value of the used SIBm and the value tag of the SIBm it holds are both 5, so it is judged that the saved SIBm can continue to be used, and it is not necessary to request and receive the SIBm in the cell 4. The UE2 determines that the cell 4 belongs to the PLMN A, and is different from the PLMN B in the valid area of the SIBm that it holds. Therefore, it is determined that the saved SIBm cannot be used currently. At the same time, UE2 determines that a new SIBm needs to be requested and received at cell 4.

In this embodiment, when the effective area range information is provided, the geographic area or logical area information included in other system information blocks in the system information may be reused or utilized. For example, the system information block related to cell reselection is configured with a co-frequency or inter-frequency neighbor list of the cell, including cell identification list information of one or more co-frequency or inter-frequency neighbor cells. Since the number of bit bits required by the cell identity is relatively large, in order to avoid repeatedly providing the same information, the system information block effective area information can reuse the cell list configuration information as much as possible.

For example, for a plurality of neighboring cells, whether a certain system information block of the current cell is valid in the neighboring cell is configured in the form of a bitmap. If the bitmap bit corresponding to a neighboring cell is configured as 1, an SIB identifying the current cell is still valid in the neighboring cell. On the UE side, the cell identification information may be copied and saved as valid area range information based on the neighbor list information and the bitmap information in the effective area range information of the system information block.

Specific embodiment 2:

Corresponding to the foregoing specific embodiment 1, there is a logical or physical management entity, such as a base station or a network management entity, on the network side to manage system information related to multiple cells or other logical or physical coverage areas, including generation, The maintenance operations such as the modification and the deletion are described in the following example. One of the functions of the entity is to make the system information blocks sent by all cells in the effective area of one system information block the same, and the system information block includes the same effective area range and version information. The information of the effective area range may be a Public Land Mobile Network Identity (PLMN ID), a Cell ID, a Transmission Receive Point (TRP ID), and Other defined area identification IDs associated with geographic or logical areas. Wherein, if an area A includes a plurality of areas B, when the information of the effective area range uses the area A, all the areas B belonging to the area A belong to the effective area range, for example, the effective area range of a certain SIB. The information is a PLMN ID. Since one PLMN may include several cells, the SIB is valid in all cells belonging to the PLMN ID.

8 is a schematic diagram of a macro cell and a base station in this embodiment. As shown in FIG. 8, in a network deployment situation in which a macro cell (cell 1) overlaps with a plurality of small cells (cell 2, cell 3), a macro is included therein. The cell and its associated base station can serve as the above-mentioned management entity, and each small cell transmits system information that will be applied to all or part of the cell. The macro cell 1 and the small cell 2 are configured with the same SIBm, including the valid area range and version information, where the information of the effective area is PLMN A, and the cell 1/2 belongs to the PLMN A, and the value tag associated with the version information Is 5. The small cell cell 3 uses another configured SIBm, including the effective area range and version information, wherein the information of the effective area range is also PLMN A, but the value tag value associated with the version information is 8.

Optionally, the cell periodically broadcasts, by using the first broadcast channel, a value tag value related to the system information block identifier currently used by the current cell and/or the version information of the system information block. The cell-related identification information, such as the PLMN ID, the cell ID, and the like to which the cell belongs, is periodically broadcasted through the first or second broadcast channel. The corresponding system information block is transmitted periodically or on demand through the second broadcast channel or the third broadcast channel. The system information block includes information of a valid area range, and may also include a value tag value related to the version information.

FIG. 9 is a schematic diagram of broadcast transmission in the embodiment. As shown in FIG. 9, when transmitting on the network side, the value tag value related to the SIBm version information is broadcasted in the MIB through the first broadcast channel (ie, broadcast channel 1). At the same time, the SIBm including the information of the effective area range is broadcasted as needed on the third broadcast channel (i.e., the broadcast channel 3) as part of the Other SI, and may also include the value tag value associated with the version information of the SIBm.

Correspondingly, on the UE side: when the UE selects a cell and successfully receives system information from the cell, the received system information is used and saved. As shown in FIG. 8, for example, UE1 and UE2 both choose to camp on cell 1, and receive and save a plurality of system information blocks from cell 1 and valid area range and version information of these system information blocks, including SIBm information blocks, The valid area range of the system information block is configured as PLMN A, and the value tag value is 5.

When the UE moves and reselects to another cell, the UE will first receive part of the system information, and obtain identification information related to the cell, such as a PLMN ID, a cell ID, etc., related to the system information block identifier and its version information currently used by the cell. Value tag. As shown in FIG. 8, when UE1 and UE2 are respectively moved from cell 1 and reselected to cell 2 and cell 3, the identification information of the cell is first obtained by using the first broadcast channel and/or the second broadcast channel respectively: PLMN A/cell 2 And the PLMN A/cell 3, and obtain the value of the system information block identifier and the version information associated with the version information of the cell (cell 2, cell 3), where cell 2 includes S IBm, and cell 2 has a value tag of 5; 3 also includes SIBm, the value tag of cell 3 is 8.

The UE compares the identification information of the new cell with the information of the valid area range of the saved system information block, determines whether the system information block is valid in the new cell, and determines whether the version information of the system information block of the new cell and the pre-saved system information are simultaneously determined. The version information of the block is the same. When the new cell identifier belongs to the effective area of the system information, and the version information of the system information block of the new cell is the same as the version information of the saved system information block, the UE will continue to use the saved system information block in the new cell; The saved cell information block is not used when the cell identity does not belong to the effective area of the system information, and/or the version information of the system information block of the new cell is different from the version information of the saved system information block. Optionally, when the new cell identifier belongs to the effective area range of the system information, and the version information of the system information block of the new cell is the same as the version information of the saved system information block, the system that does not request and/or receive the new cell transmission is not requested. Information block; when the new cell identity does not belong to the effective area of the system information, and/or the version information of the system information block of the new cell is different from the version information of the saved system information block, requesting and/or receiving in the new cell The system information block sent by the cell. As shown in FIG. 8, when UE1 and UE2 are respectively moved from cell 1 and reselected to cell 2 and cell 3, UE1 determines that cell 2 belongs to PLMN A, and is the same as PLMN A in the valid area of the SIBm it holds, so cell 2 is Within the valid area of the saved SIBm, the value tag value of the SIBm currently used by the cell and the value tag of the SIBm stored by the cell are both 5, so it is determined that the saved SIBm can continue to be used, and does not need to be requested in the cell 2 Receive SIBm. The UE2 determines that the cell 3 belongs to the PLMN A, and is the same as the PLMN A in the valid area of the saved SIBm. However, the value tag (5) of the SIBm currently used by the cell 3 is different from the value tag (8) of the SIBm stored therein, so it is determined. The saved SIBm cannot be used in the current cell. At this time, the UE 2 judges that it is necessary to request and receive a new SIBm at the cell 3.

In summary, the method in the foregoing embodiment enables the UE to determine whether to continue to use the system information block according to the saved system information block and its corresponding valid area range and version information when moving and reselecting to a new cell. The new cell is in the effective area and the version information is also valid. The UE requests and receives the corresponding system information block differently, thereby reducing the process of the UE sending the request message and receiving the system information, and also reducing the network side base station sending according to the request. The process of system information. Therefore, on the one hand, the power consumption of the UE and the base station can be reduced, and on the other hand, the access speed of the UE in the new cell can be accelerated.
