The system message transmission method, device and storage medium provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

Fig. 2 is a flowchart of a system message transmission method provided by an embodiment of the present disclosure, where the method is performed by a first type of terminal device, and as shown in fig. 2, the system message transmission method may include the following steps:

step 201, a first broadcast message sent by a network device is obtained.

In one embodiment of the present disclosure, the first type of terminal device may be an eRedcap UE.

In an embodiment of the present disclosure, the first broadcast message may be dedicated for use by the first type of terminal device, that is, the first broadcast message is only sent to the first type of terminal device, and the physical resource of the channel corresponding to the first broadcast message is less than or equal to the maximum resource capability supported by the first type of terminal device. Specifically, the physical resource capacity of the channel corresponding to the first broadcast message is less than or equal to the maximum resource capacity supported by the first class of terminal devices may include at least one of the following:

The bandwidth of the channel corresponding to the first broadcast message is smaller than or equal to the maximum bandwidth (namely 5 MHz) supported by the data channel of the first type of terminal equipment;

the number of PRBs of the channel corresponding to the first broadcast message is smaller than or equal to the number of PRBs supported by the maximum data channel of the first type of terminal equipment;

the TBS (transport block size ) of the first broadcast message is less than or equal to the TBS maximally supported by the first class of terminal devices.

Further, in one embodiment of the present disclosure, at least one of SIBs (System Information Blocks ) may be included in the first broadcast message. That is, the first broadcast message may include all SIBs, or the first broadcast message includes only part of the SIBs, e.g., the first broadcast message may include only SIB2 and/or SIB3 (including only SIB2 or only SIB3 or both SIB2 and SIB 3), then this means: the network device configures only SIB2 and/or SIB3 used exclusively for the first type of terminal device, and does not configure other SIBs used exclusively for the first type of terminal device, and at this time, when the first type of terminal device is to acquire SIB2 and/or SIB3, SIB2 and/or SIB3 may be acquired by acquiring the first broadcast message.

In summary, in the system message transmission method provided in the embodiments of the present disclosure, the first broadcast message adapted to the resource capability of the first type of terminal device is configured separately, where the first broadcast message is dedicated for use by the first type of terminal device and includes at least one of the system messages. Therefore, the first type terminal equipment can acquire the system information by receiving the first broadcast information sent by the network equipment, and the system information is not required to be acquired in a mode of limiting the resources occupied by the corresponding channels of the system information shared by all terminals, so that the flexibility of scheduling the system information is ensured not to be reduced while the first type terminal equipment can successfully receive the system information.

Fig. 3 is a flowchart of a system message transmission method provided by an embodiment of the present disclosure, where the method is performed by a first type of terminal device, and as shown in fig. 3, the system message transmission method may include the following steps:

step 301, acquiring a first broadcast message sent by a network device.

The detailed description of step 301 may be described with reference to the above embodiments, which are not repeated herein.

Step 302, obtaining a second broadcast message sent by the network device, where the second broadcast message is shared by the first type of terminal device and the second type of terminal device, and a transmission resource occupied by a channel corresponding to the second broadcast message is less than or equal to a maximum resource capability supported by the first type of terminal device.

In one embodiment of the present disclosure, the capability of the second type of terminal device is stronger than the capability of the first type of terminal device, which is specifically at least one of the following:

the bandwidth of the data channel of the first type of terminal equipment is smaller than that of the second type of terminal equipment, such as the RF (Radio Frequency) bandwidth of the data channel of the first type of terminal equipment is smaller than that of the data channel of the second type of terminal equipment, and/or the processing bandwidth of the baseband of the data channel of the first type of terminal equipment is smaller than that of the baseband of the data channel of the second type of terminal equipment; the RF bandwidth herein refers to the maximum frequency bandwidth that the terminal can receive. The processing bandwidth of the baseband refers to the maximum bandwidth that can be processed when the terminal performs baseband processing, for example, performing corresponding FFI (fast fourier transform)/IFFT (inverse fast fourier transform), and demodulating data. The baseband processing bandwidth may be equal to or less than the RF bandwidth.

The number of PRBs supported by the first type of terminal equipment data channels is smaller than the maximum number of PRBs supported by the second type of terminal equipment data channels.

For example, the first type of terminal device may be an eRedCap terminal, and the second type of terminal device may be a RedCap terminal or a normal NR terminal and LTE terminal.

And, it should be noted that, in one embodiment of the present disclosure, the second broadcast message includes a plurality of SIBs, where, for other SIBs not included in the first broadcast message, the first type terminal device may acquire the other SIBs by acquiring the second broadcast message, and, for example, assuming that only SIB1 is included in the first broadcast message, when the first type terminal device is to acquire SIB2, SIB2 may be acquired by acquiring the second broadcast message.

Further, in one embodiment of the present disclosure, in order to ensure that the first type of terminal device can successfully receive the other SIB, the transmission resource occupied by the channel corresponding to the second broadcast message should be less than or equal to the maximum resource capability supported by the first type of terminal device. For example, the bandwidth of the channel corresponding to the second broadcast message is less than or equal to the maximum bandwidth (i.e. 5 MHz) supported by the data channel of the first class of terminal equipment; and/or the number of PRBs of the channel corresponding to the second broadcast message is smaller than or equal to the number of PRBs supported by the maximum data channel of the first type of terminal equipment; and/or the TBS number of the second broadcast message is smaller than or equal to the TBS supported by the first type terminal equipment.

Further, in one embodiment of the present disclosure, the first broadcast message and the second broadcast message include at least one of the following differences:

The RNTIs (radio network temporary identifier, radio network temporary identities) used are different;

the search spaces used for the corresponding control channels are different;

CORESET (Control Resource SET, set of control resources) for the corresponding control channels are different;

the timing of the transmission is different.

In summary, in the system message transmission method provided in the embodiments of the present disclosure, a first broadcast message adapted to the resource capability of the first type of terminal device is configured separately, where the first broadcast message is dedicated for use by the first type of terminal device and includes at least one of the system messages. Therefore, the first type terminal equipment can acquire the system information by receiving the first broadcast information sent by the network equipment, and the system information is not required to be acquired in a mode of limiting the resources occupied by the corresponding channels of the system information shared by all terminals, so that the flexibility of scheduling the system information is ensured not to be reduced while the first type terminal equipment can successfully receive the system information.

Fig. 4 is a flowchart of a system message transmission method provided by an embodiment of the present disclosure, where the method is performed by a first type of terminal device, and as shown in fig. 4, the system message transmission method may include the following steps:

Step 401, acquiring a first broadcast message sent by a network device.

The detailed description of step 401 may be described with reference to the above embodiments, which are not repeated herein.

And step 402, receiving partial content of the second broadcast message in response to the transmission resource occupied by the second broadcast message being greater than the maximum resource capacity supported by the first type of terminal equipment, wherein the second broadcast message is shared by the first type of terminal equipment and the second type of terminal equipment.

the bandwidth of the data channel of the first type of terminal equipment is smaller than that of the second type of terminal equipment, for example, the RF bandwidth of the data channel of the first type of terminal equipment is smaller than that of the data channel of the second type of terminal equipment, and/or the processing bandwidth of the baseband of the data channel of the first type of terminal equipment is smaller than that of the baseband of the data channel of the second type of terminal equipment; for example, the first type of terminal device may be an eRedCap terminal, and the second type of terminal device may be a RedCap terminal or a normal NR terminal, LTE terminal; the number of PRBs supported by the first type of terminal equipment data channels is smaller than the maximum number of PRBs supported by the second type of terminal equipment data channels.

It should be noted that, in one embodiment of the present disclosure, for other SIBs not included in the first broadcast message, the first type terminal device may acquire the other SIBs by acquiring the second broadcast message, and, for example, assuming that only SIB1 is included in the first broadcast message, when the first type terminal device is to acquire SIB2, SIB2 may be acquired by acquiring the second broadcast message.

Further, in one embodiment of the present disclosure, when the transmission resource occupied by the second broadcast message is greater than the maximum resource capability supported by the first type of terminal device, in order to ensure that the first type of terminal device can successfully receive the other SIB, the first type of terminal device may only receive part of the content of the second broadcast message for demodulation. Wherein the portion of the content should match the reception capability supported by the first type of terminal device to be successfully received by the first type of terminal device.

And, it should be noted that, because the robustness of the system message is large, even if only part of the content of the second broadcast message is accepted, the accuracy of the system message acquisition is not affected.

The RNTIs used are different;

the search spaces used for the corresponding control channels are different;

CORESET of the corresponding control channel is different;

the timing of the transmission is different.

Furthermore, it should be noted that, in an embodiment of the present disclosure, when the SIB included in the first broadcast message is indicated, physical resources corresponding to the SIB included in the first broadcast message may also be indicated at the same time, so that the first type of terminal device may receive the SIB that is specifically used by the first type of terminal device based on the physical resources.
