The starting position of the (Control Resource Set, CORESET) is divided into a precoding resource block group (Precoding Resource Block Group, PRG). After the terminal obtains the RMSI, the division of the PRG takes the starting reference point of the CC as the starting point.

The network device configures a set of SIB1 on the initial BWP to share with different terminals. However, since the terminal updating the system information has obtained the RMSI, the division of the PRG is based on the starting reference of CC. point as the starting point, and the terminal that performs initial access has not obtained the RMSI, and its PRG division is based on the starting position of the CORESET scheduled by broadcast information to divide the PRG, so that these terminals will not be able to share SIB1.

It should be noted that in the embodiment of the present invention, only the base station in the NR system is used as an example, but the specific type.

The base stations may communicate with the terminal 11 under the control of a base station controller, which in various examples may be part of a core network or some base station. Some base stations may communicate control information or user data with the core network through the backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. Wireless communication systems may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on these multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies.

UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions.

An embodiment of the present invention provides a system information configuration method, which is applied to a communication device. The communication device may be a terminal or a network device. As shown in FIG. 2 , the method includes the following steps:

Step 21: In the case of scheduling the system information block by activating the bandwidth part BWP, transmit the system information block according to the starting position of the precoding resource block group PRG in the activated BWP. Wherein, the starting position of the PRG is related to at least one of the target control resource set CORESET and the update indication information of the system information block, and the activated BWP overlaps with at least part of the frequency domain resources of the initial BWP.

The activated BWP is one of multiple BWPs supported by the network device and the terminal, and the initial BWP is the default BWP of the system, that is, the BWP used by default when the terminal does not access the system. The overlapping of at least part of the frequency domain resources of the activated BWP and the initial BWP means that the frequency domain resources of the activated BWP and the initial BWP overlap. For example, as shown in Figure 3, the frequency domain resources of the activated BWP completely overlap with the frequency domain resources of the initial BWP; or, as shown in Figure 4, the starting position of the frequency domain resources of the activated BWP and the starting position of the frequency domain resources of the initial BWP The start position is aligned; or, the end position of the frequency domain resource of the activated BWP not shown in the figure is aligned with the end position of the frequency domain resource of the initial BWP; or, as shown in Figure 5, the frequency domain resource of the activated BWP contains the initial BWP complete frequency domain resources. It should be noted that the target CORESET may refer to a control resource set whose frequency domain resources overlap with the frequency domain resources of the initial BWP.

The system information block mentioned here may refer to SIB1. When the network device schedules the SIB1 for the terminal by activating the BWP, the network device may send the SIB1 according to the starting position of the PRG in the activated BWP. Correspondingly, the terminal receives SIB1 according to the starting position of the PRG in the activated BWP. In the traditional technology, the starting position of the PRG in the activated BWP is related to the component carrier CC where the activated BWP is located. In this way, when other terminals perform initial access through the initial BWP that overlaps the frequency domain of the activated BWP, the initial BWP The starting position of the PRG is related to the control resource set CORESET, so that on the same frequency domain resource, terminals in different states consider the starting position of the PRG to be different, and the division result of the PRG may also be different. In order to avoid the above problem, the starting position of the PRG can be determined according to at least one of the target CORESET and the update indication information of the system information block, so as to avoid the interference problem of the network equipment configuring the system information block for different terminals.

Wherein, the embodiments of the present invention include but are not limited to the following ways of determining the starting position of the PRG:

Mode 1: The starting position of the PRG in the activated BWP is related to the target CORESET.

In this way, when the current activated BWP of the terminal overlaps with at least part of the frequency domain resources of the initial BWP, if the terminal receives the update instruction information for updating the system information block, it determines the starting position of the PRG in the activated BWP according to the target CORESET, Thereby, the division result of the PRG in the activated BWP is determined, and the system message block sent by the network device is received according to the division result of the PRG.

Specifically, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET. The minimum resource block index of the target CORESET is scheduled or indicated by a physical broadcast channel (Physical Broadcast Channel, PBCH). The minimum resource block index of the target CORESET may be 0, then the starting position of the PRG in the activated BWP may be determined according to CORESET0. As shown in Figures 3 to 5, the starting position of the PRG in the activated BWP may be the starting position of CORESET0, wherein the target CORESET is the set of all control resources in the initial BWP, and the starting point in the frequency domain of CORESET0 may be the same as the frequency domain of the initial BWP. The starting point is the same.

That is to say, in the case where the frequency domain resources of the terminal's activated BWP and the initial BWP overlap, if the network device indicates that the terminal needs to update the system information, after the terminal obtains the update instruction information for updating the system information, it is assumed that the PRGs in the activated BWP are divided. The starting position is the starting point of CORESET0.

Mode 2: The starting position of the PRG in the activated BWP is related to the update indication information of the target CORESET and the system information block.

In this way, scenario 1, when at least part of the update indication information is configured on the target CORESET, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET. Specifically, when the current activated BWP of the terminal overlaps with at least part of the frequency domain resources of the initial BWP, if the terminal receives the update instruction information for updating the system information block, indicating that at least part of the system information block is configured on the target CORESET, the terminal according to the target CORESET The starting position of the PRG in the activated BWP is determined, so as to determine the division result of the PRG in the activated BWP, and the system message block sent by the network device is received according to the division result of the PRG.

Specifically, in this scenario, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET, such as CORESET0. As shown in FIGS. 3 to 5 , the starting position of the PRG in the activated BWP may be the starting position of CORESET0, and the starting point in the frequency domain of CORESET0 may be the same as the starting point in the frequency domain of the initial BWP.

That is to say, in the case where the frequency domain resources of the terminal's activated BWP and the initial BWP overlap, if the network device indicates that the terminal needs to update the system information, after the terminal obtains the update instruction information for updating the system information, if the update instruction information indicates that the system information At least part of the block is configured on the target CORESET, then the terminal assumes that the starting position of the PRG division in the activated BWP is the starting point of CORESET0.

On the other hand, in the second scenario, when the update indication information is not configured on the target CORESET, the starting position of the PRG is determined according to the component carrier CC where the activated BWP is located. Specifically, when the current activated BWP of the terminal overlaps with at least part of the frequency domain resources of the initial BWP, if the terminal receives the update instruction information for updating the system information block, indicating that the system information block is not configured on the target CORESET, the terminal will determine the location of the activated BWP according to the location of the target CORESET. The CC determines the starting position of the PRG in the activated BWP, thereby determining the PRG division result in the activated BWP, and receives the system message block sent by the network device according to the PRG division result.

Specifically, in the second scenario, the starting position of the PRG is determined according to the minimum resource block index of the CC. As shown in FIG. 6 , when the activated BWP is BWP1, BWP2, BWP3 or BWP4, the starting position of the PRG in the activated BWP may be the starting position of CC1.

That is to say, in the case where the frequency domain resources of the terminal's activated BWP and the initial BWP overlap, if the network device indicates that the terminal needs to update the system information, after the terminal obtains the update instruction information for updating the system information, if the update instruction information indicates that the system information If the block is not configured on the target CORESET, the terminal assumes that the starting position of the PRG division in the activated BWP is the starting position of the CC where the activated BWP is located.

The starting position of the PRG in the activated BWP is briefly described above with respect to the first mode and the second mode respectively. The following embodiment will further introduce the relevant description of updating the line update indication information of the system information block.

The update indication information in the embodiment of the present invention is carried in a Physical Downlink Control Channel (PDCCH), that is, the network device indicates through the PDCCH that the terminal needs to update the system information.

Further, the PRG in the activated BWP is the PRG of the activated physical downlink shared channel (Physical Downlink Share Channel, PDSCH) on the BWP, and the PDSCH is scheduled by the PDCCH.

Taking mode 1 as an example, in the case where the frequency domain resources of the terminal's activated BWP and the initial BWP overlap, if the network device indicates through the PDCCH that the terminal needs to update the system information, after the terminal receives the PDCCH, it is assumed that the PDCCH schedule carries the system information. The starting point of the PRG division of the PDSCH of the block is from the minimum resource block index of the CORESET indicated by the PBCH (that is, starting from the starting point of CORESET 0).

Taking mode 2 as an example, in the case where the frequency domain resources of the terminal's activated BWP and the initial BWP overlap, if the network device indicates through the PDCCH that the terminal needs to update the system information, after the terminal receives the PDCCH, if the PDCCH indicates at least the system information block. If the part is configured on the target CORESET, the terminal assumes that the starting point of the PRG division of the PDSCH carrying the system information block scheduled by the PDCCH starts from the minimum resource block index of the CORESET indicated by the PBCH (that is, the starting point of CORESET 0). If the PDCCH indicates that the system information block is not configured on the target CORESET, the terminal assumes that the starting point of the PRG division of the PDSCH carrying the system information block scheduled by the PDCCH starts from the minimum resource block index of the CC where the BWP is activated.

In the system transmission method of the embodiment of the present invention, the network device or terminal transmits the system information block according to the starting position of the PRG in the activated BWP, and the starting position of the PRG is related to the indication information of the target CORESET and the system information block, so that the overlapping frequency domain is used. Different terminals of the resource can share the system information block.

The above embodiments respectively introduce the system information transmission methods in different scenarios in detail, and the corresponding communication devices thereof will be further described in this embodiment below with reference to the accompanying drawings.

As shown in FIG. 7 , the communication device 700 according to the embodiment of the present invention can realize that in the case of scheduling the system information block by activating the bandwidth part BWP in the above embodiment, according to the starting position of the precoding resource block group PRG in the activated BWP, The details of the method for transmitting the system information block, and achieve the same effect, wherein the starting position of the PRG is related to at least one of the target control resource set CORESET and the update indication information of the system information block, and the activated BWP and at least part of the initial BWP are related.

The starting position of the PRG is determined according to the minimum resource block index of the target CORESET.

Wherein, when at least part of the update indication information is configured on the target CORESET, the starting position of the PRG is determined according to the minimum resource block index of the target CORESET;

Wherein, when the update indication information is not configured on the target CORESET, the starting position of the PRG is determined according to the component carrier CC where the activated BWP is located.

Wherein, the communication device is a network device or a terminal.
