Description
Technical Field
The present invention relates to communications technologies, and in particular, to a method and an apparatus for receiving information, and a computer-readable storage medium.
Background
In 4G and 5G networks, System Information, except for a Master Information Block (MIB) and a System Information Block SIB 1(System Information Block), is carried by System messages (SI). Each SI message contains one or more SIBs with the same scheduling requirements, except for SIB1, which have the same transmission period. For example: the 2 SIBs with transmission periods of 160ms can be placed in the same SI message, but other SIBs with transmission periods of 320ms must be placed in different SI messages, each SI message is transmitted in only one SI window (SI-windows), and the following set rules are satisfied:
1. an SI message is associated with an SI window, and the SI message can only be sent in the SI window and can be repeatedly sent for a plurality of times, but other SI messages can not be sent;
2. the SI windows are close to each other, so that the SI windows are not overlapped and have no gap;
3. the lengths of SI windows of all SI messages are the same;
4. the periods of different SI messages are independent of each other.
As shown in FIG. 1, assume that SIB3 and SIB4 are transmitted in SI-1 with a period of 160 ms; SIB5 and SIB6 are transmitted in SI-2 with a period of 320 ms; SIB7 and SIB8 are transmitted in SI-3 with a period of 640 ms.
In the NR-U, the base station and the UE need to monitor the channel before sending data, and data transmission, including transmission of system information, can be performed only when the channel is idle, and if the NR-U also adopts the system information transmission method used in L TE/NR, the following problems can be caused:
the base station needs to perform channel monitoring before sending each SI message. If the base station detects that the channel is busy in the SI-window corresponding to the SI-1, the base station cannot send the SI-1 in the current SI-window, and if the sending period of the SI-1 is 320ms, the base station needs to wait for 320ms before sending the SI-1, and the base station may still detect that the channel is busy after 320ms, and therefore cannot complete the transmission of the SI-1 in the SI-window. However, the UE cannot receive the SI message for a period of time, which will cause performance such as cell reselection and access control mechanism to be affected.

In combination with the foregoing embodiments, there are provided a total of three alternative ways to indicate broadcast status.
Example one
1. SI-window suitable for all SI messages
Fig. 3 is a flowchart of a method for receiving an SI message according to an embodiment of the present invention, and the following describes the method for receiving an SI message according to the embodiment with reference to fig. 3.
In step S11, the UE receives the system information scheduling information sent by the base station. In this embodiment, a UE is taken as an implementation main body of the information receiving method of this embodiment, and a base station is taken as a network side for example, where the system information scheduling information includes: SI-window configuration information. Wherein the SI-window configuration information indicates the length of the SI-window, assuming 40 ms.
Step S12, the UE receives all SI messages in the first SI-window, and knows that four SI messages SI-1/SI-2/SI-3/SI-4 and the value tags corresponding to the four SI messages are received through the specific information of the SIB/SI message broadcasted this time carried in SI-1. If the UE is interested only in SI-1 and SI-2, there is no need to decode the third and fourth transport blocks (SI messages); or if the UE finds that the value tag of the SI message of interest to itself has not changed, it is also not necessary to decode these received SI messages.
In step S13, when SI-periodicity of SI-1 arrives, that is, SFN is 8, the base station listens to the channel. But the channel is always busy in this SI-window. Therefore, the base station cannot transmit SI-1 in the SI-window.
In step S14, the base station continues to monitor the channel in the following SI-window. And when the channel is monitored to be idle, sending the SI-1 and indicating that the transmission only sends the SI-1.
Alternatively, as shown in fig. 4, the UE may not configure the SI-window length, and directly set it to the smallest period, i.e. 80ms, in the SI message period.
Example two
2. Configuring multiple SI-windows suitable for different SI message groups
Fig. 5 is a flowchart of a method for receiving an SI message according to an embodiment of the present invention, and the following describes the method for receiving an SI message according to the embodiment with reference to fig. 5.
In step S21, the UE receives the system information scheduling information sent by the network side. Here, the system information scheduling information includes: the mapping relation between SIB and SI information, the mapping relation between SI information and SI information group, the mapping relation between SI information group and SI-window, SI-window configuration information, and SI information period.
In step S22, it is assumed that the SI-1 period is 160ms, the SI-2 period is 160ms, the SI-3 period is 320ms, and the SI-4 period is 320 ms. Mapping SI-1 and SI-3 into an SI message group 1, and using a first SI-window; mapping SI-2 and SI-4 to SI message group 2, using a second SI-window; the SI-window length is 80 ms.
At step S23, as indicated by the vertical arrow, SI-1 cannot be transmitted in the configured SI window # 1 because the channel has been busy for the previous time. In order to ensure the timely transmission of the system information, the SI-1 which is not transmitted in time can be sent in the SI window # 2, and only the header needs to indicate that the broadcast broadcasts not only the SI-2 but also the SI-1.
The receiving method of the SI message provided in this embodiment can avoid that the base station occupies the data channel for a long time to send the broadcast message, thereby causing an impact on downlink data transmission and last scheduling.
