It should be noted that, in this embodiment of the present invention, the "reception time period for M data blocks" in the above S202 may be understood as a reception time period for each of the M data blocks. Specifically, when a certain data block includes a paging message, the receiving time period for the data block may be the listening time period of the paging message. When a certain data block includes ETWS information, the receiving time period for the data block may be the receiving time period of the ETWS information, and when a certain data block includes CMAS information, the receiving time period for the data block may be the receiving time period of the CMAS information. The receiving time period, when a certain data block includes data transmitted on the target logical channel, the receiving time period for the data block may be the receiving time period of the data transmitted on the target logical channel.

It can be understood that, in this embodiment of the present invention, when the target data block includes a paging message, in the above S202, the UE receiving the target data block according to the M reception priorities can be understood as the UE monitoring the paging message according to the M reception priorities. Specifically, when the network device pages the UE, the UE can monitor the paging message, and when the network device does not page the UE, the UE cannot monitor the paging message.

The following is an example of the receiving time period for the M data blocks including the receiving time period of the CMAS information and the listening time period of the paging message, and the receiving time period for the M data blocks including the receiving time period of the ETWS information and the CMAS information. For example, with reference to FIG. 3 , the overlapping of the receiving time periods for M data blocks is exemplarily described.

Exemplarily, FIG. 3 is a schematic diagram of overlapping reception time periods for M data blocks according to an embodiment of the present invention. In one case, as shown in (a) in Figure 3, it is assumed that the UE needs to periodically monitor the paging message through the SIM card 1, and needs to receive the CMAS information through the SIM card 2, that is, the M data blocks include the paging message and the CMAS. information. The listening time period 1 of the paging message (that is, the UE can monitor the paging message in the time period 1) does not overlap with the receiving time period 4 of the CMAS information (that is, the listening time period 1 of the paging message and the receiving time of the CMAS information) segment 4 does not conflict), the listening time period 2 of the paging message overlaps with the receiving time period 4 of the CMAS information, and the listening time period 3 of the paging message and the receiving time period 4 of the CMAS information (that is, the listening time period of the paging message 2 conflicts with the reception period 4 of the CMAS information, and the listening period 3 of the paging message conflicts with the reception period 0 of the CMAS information). In this case, if the receiving priority of the CMAS information is higher than the receiving priority of the paging message, the UE can receive the CMAS information preferentially in the receiving period 4, and no longer monitor the paging in the listening period 2 and the listening period 3. information.

In another case, as shown in (b) of FIG. 3 , it is assumed that the UE needs to receive ETWS information through SIM card 1 and CMAS information through SIM card 2, that is, the M data blocks include ETWS information and CMAS information. The receiving time period 5 of the ETWS information overlaps with the receiving time period 6 of the CMAS information (that is, the receiving time period 5 of the ETWS information and the receiving time period 6 of the CMAS information conflict). In this case, if the receiving priority of the ETWS information is higher than the receiving priority of the CMAS information, the UE may receive the ETWS information preferentially.

It should be noted that, in this embodiment of the present invention, among the M pieces of data listed above, since the importance/urgency of the ETWS information is usually the highest, it can be predefined that the receiving priority of the ETWS information is the highest, or the network device can configure or Indicates that ETWS information is received with the highest priority.

Optionally, in this embodiment of the present invention, the receiving priority of the data block may be set according to the same rule. For example, the receiving priority of the data block can be set according to the importance/urgency of the data block. Specifically, the receiving priority of the data block may be predefined according to the importance/urgency of the data block, and the network device may also configure or indicate the receiving priority of the data block for the UE according to the importance/urgency of the data block.

Optionally, in this embodiment of the present invention, the degree of importance/urgency of the data block may be determined according to the content of the data block. It can be understood that, in this embodiment of the present invention, for data blocks with the same or similar content, the importance/urgency may be the same. In this way, the predefined receiving priority, the receiving priority configured or indicated by the network device may be the same. For data blocks with completely different contents, their importance/urgency levels are completely different, so that the predefined receiving priority, the receiving priority configured by the network device or the indicated receiving priority may be different. Specifically, it will be described in detail in the following embodiments, and will not be repeated here.

Exemplarily, the receiving priorities of ETWS information configured by different network devices may be the same, the receiving priorities of CMAS information configured by different network devices may be the same, the receiving priorities of paging messages configured by different network devices may be the same, and the receiving priorities of different network devices may be the same. The receiving priorities of the data blocks transmitted on the logical channels corresponding to the SRBs may be the same, and the receiving priorities of the data blocks transmitted on the logical channels corresponding to the DRBs configured by different network devices may be the same.

It should be noted that the network device may also set different reception priorities for CMAS information with different specific contents, for example, the reception priorities of CMAS information for preventing fire and CMAS information for preventing thieves may be different.

Optionally, in this embodiment of the present invention, since the contents of the ETWS information and the CMAS information are similar, the receiving priorities of the ETWS information and the CMAS information may be the same or different.

In the data transmission method provided by the embodiment of the present invention, since the receiving priority of each data block is predefined, the network device sending the data block is configured by system information or downlink control signaling, or the network device sending the data block Indicated by the paging downlink control information or the paging message, so when the receiving time periods for the M data blocks to be received by the UE overlap, the UE shall receive the M data blocks according to the receiving priorities (that is, the M receiving priorities) Receiving data blocks can ensure that the UE preferentially receives data blocks with high receiving priority. In this way, when the network devices in the networks subscribed by different SIM cards send downlink data to the UE within the same time period, it can be ensured that the UE can receive data with a higher receiving priority, thereby ensuring that the UE receives important data to a certain extent. .

Optionally, in the data transmission method provided by the embodiment of the present invention, the foregoing S202 may be specifically implemented by the following S202a, S202b, or S202c.

S202a. In the case that the receiving time periods for the M pieces of data overlap, the UE receives the first data block, and the receiving priority of the first data block is lower than the receiving priority of the second data block, the UE stops receiving the first data block , and start receiving the second data block.

In the embodiment of the present invention, the first data block and the second data block are different data blocks in the above-mentioned M data blocks, and the transmission time of the first data block is earlier than the transmission time of the second data block. That is to say, the UE is receiving the first data block, the network device sends the second data block to the UE, and within a receiving time period, the UE can only receive one data block among the M data blocks. If the receiving priority is lower than the receiving priority of the second data block, the UE may stop receiving the first data block and start receiving the second data block.

Optionally, in this embodiment of the present invention, the UE may start to receive the second data block at the time when the reception time period of the second data block starts to receive the second data block, and the UE may also start to receive the second data block at the time when the UE stops receiving the first data block. block, which is not specifically limited in this embodiment of the present invention.

It should be noted that, in this embodiment of the present invention, when the UE stops receiving the first data block, the UE may suspend receiving the first data block, and the UE can wait for the completion of receiving the data block with a high receiving priority, and then the UE continues to receive or re-receive the first data block. A data block; if the UE stops receiving the first data block, the UE may cancel receiving the first data block, and the UE may discard part of the data in the received first data block, which is not specifically limited in this embodiment of the present invention.

In this embodiment of the present invention, if the receiving time periods of multiple data blocks overlap, if the UE is receiving a first data block with a lower receiving priority, in the process of receiving the first data block, if the UE needs to receive A second data block. Since the receiving priority of the second data block is higher than that of the first data block, it means that the second data block is more important than the first data block, and the UE stops receiving the first data block. , and start to receive the second data block, so that more important data can be received preferentially, and the UE is prevented from missing important data.

S202b. In the case that the receiving time periods for the M data blocks overlap, the UE receives the third data block according to the above-mentioned M receiving priorities, and abandons receiving the fourth data block.

The third data block is a data block with the highest receiving priority among the M data blocks, and the fourth data block is a data block other than the third data block among the M data blocks.

It should be noted that, in this embodiment of the present invention, the data block with the highest receiving priority may include at least one data block. For example, the third data block includes multiple data blocks with the same receiving priority, and the UE may follow the multiple data blocks. The send time receives the data block with the earliest send time.

It should be noted that, in this embodiment of the present invention, the network device may retransmit the fourth data block if the UE does not receive the fourth data block, and the UE may re-receive the fourth data block if there is no reception conflict.

In this embodiment of the present invention, when the receiving time periods for the M data blocks overlap, the UE may receive the third data block with the highest receiving priority according to the receiving priorities of the M data blocks (that is, the M receiving priorities). data blocks, and give up receiving the data blocks except the third data block among the M data blocks, it can ensure that the UE can receive the data with the highest receiving priority, and thus can ensure that the UE receives important data to a certain extent.

S202c: In the case where the receiving time periods for the M data blocks overlap, the UE sequentially receives at least two of the M data blocks according to the M receiving priorities and in descending order of the M receiving priorities data blocks.

Specifically, the UE may receive the data block with the second highest priority after receiving the data block with the highest priority.

Optionally, as shown in FIG. 4 , in the data transmission method provided by the embodiment of the present invention, before the foregoing S201 , the following S203 may be further included.

S203. The UE acquires M reception priorities.

The M priorities may be predefined, or configured by the network device for the UE, or indicated by the network device for the UE.

In the embodiment of the present invention, the contents of the above-mentioned M data blocks are different, and the manner in which the UE acquires the receiving priority (ie, the receiving priority of the M data blocks) is different. Hereinafter, when the M data blocks include the first type of data block, the second type of data block or the third type of data block, the manner in which the UE obtains the receiving priority will be exemplarily described.

Case 1: The M data blocks include the first type of data blocks

Optionally, in the data transmission method provided by the embodiment of the present invention, in the case that the M data blocks include the first type of data blocks, the above S203 may be specifically implemented by the following S203a.

In this embodiment of the present invention, the receiving priority of the first type of data block may be predefined, or indicated by the first network device (which is a network device in the above at least one network device) through the first paging downlink control information, Or it may be indicated by the first network device through the first paging message, or it may be configured by the first network device through the first system information, and the first network device is a network device that sends the first type of data block.

It can be understood that, before sending the first type of data block, the first network device may send the first paging downlink control information to the UE, or send the first paging message to the UE, or send the first system information to the UE to Indicates the receiving priority of the UE's first type of data block.

Exemplarily, the UE may obtain the receiving priority of the ETWS information or the CMAS information by paging the downlink control information; alternatively, the UE may obtain the receiving priority of the ETWS information or the CMAS information by using the paging message; or the UE may obtain the receiving priority of the ETWS information or the CMAS information through the SIB1 Reception priority of ETWS information or CMAS information.

It should be noted that, if the M data blocks include multiple first-type data blocks, the multiple first-type data blocks may be sent by different network devices.

Optionally, the receiving priority of the first type of data block is indicated by the first network device through the first paging downlink control information or the first paging message.

The first paging downlink control information or the second paging downlink control information includes first indication information, the first indication information is used to indicate that the content of the first type of data block changes, and the second paging downlink control information is scheduling Downlink control information of the first paging message.

For example, when an earthquake or tsunami occurs, the content of the ETWS information changes, the first network device can send the first paging downlink control information to the UE, and the first paging downlink control information can carry the receiving priority 1 and indicate the ETWS The content of the information changes, and the receiving priority 1 is the receiving priority of the UE for receiving the content of the ETWS information. After receiving the first paging downlink control information, the UE can obtain and receive the information through the first paging downlink control information. Priority 1, then the UE receives the ETWS information within the reception time period of the ETWS information based on the reception priority 1.

Based on this solution, when the content of the first type of data block changes, the network device can send the first paging downlink control information indicating the content of the first type of data block to the UE to carry the first type of data whose content has changed The receiving priority of the data block, so that the UE can obtain the receiving priority of the first type of data block through the first paging downlink control information or the first paging message, so that the UE can receive data when the receiving time periods overlap , the data block with higher priority is received first.

The third paging downlink control information includes first indication information, where the first indication information is used to indicate that the content of the first type of data block changes.

For example, when the UE receives the third paging downlink control information sent by the network device, and the third paging downlink control information carries the content indicating that the ETWS information or the CMAS information has changed, the UE can read the configuration in SIB1 sent by the network device. The receiving priority of the ETWS information or the receiving priority of the CMAS information after the changed content.

It can be understood that in the case where the UE does not receive the third paging downlink control information, that is, the content of the first type of data block has not changed, the UE does not need to receive the first type of data block, so the UE does not need to obtain the first type of data. The receive priority of the block.

In this embodiment of the present invention, after the UE receives the third paging downlink control information sent by the network device, the UE can quickly determine that the content of the first type of data block changes according to the third paging downlink control information, and then pass the first The system information acquires the reception priority of the first type of data block, so that data with a higher degree of importance or a higher degree of urgency can be preferentially received according to the reception priority acquired in the first system information.
