Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a data transmission method and device.

Background

With the development of mobile communication technology, more and more User Equipment (User Equipment) may install a plurality of subscriber identity modules (Subscriber Identification Module, SIM) cards, and the UE may access networks subscribed to these SIM cards.

Generally, due to hardware limitation of the UE, the UE may not be able to receive data from networks subscribed by multiple SIM cards at the same time, and thus the UE may generally receive data from networks subscribed by multiple SIM cards in a time division multiplexing manner. In this way, when the network device in the network subscribed by the plurality of SIM cards sends downlink data to the UE in the same time period, the UE may only receive data from the network subscribed by one SIM card in the time period, so that the UE cannot receive data from the network subscribed by the other SIM card in the time period, which may further cause that the UE cannot receive some important data.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In this context "/" means "or" for example, a/B may mean a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. "plurality" means two or more than two.

The terms first and second and the like in the description and in the claims, are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order of the objects. For example, the first paging message and the second paging message, etc., are used to distinguish between different paging messages, and are not used to describe a particular order of paging messages.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

Some terms/nouns involved in embodiments of the invention are explained below.

1. System information (System Information, SI)

SI transmitted by a network device may be divided into a plurality of system information blocks (System Information Block, SIB), e.g., SIB1, SIB6, SIB7, SIB8, etc., according to the purpose and content. SIB1 is used for indicating whether the UE is allowed to access a scheduling information block of a cell and other SIBs, SIB6 includes primary information of an earthquake tsunami warning system (Earthquake and Tsunami Warning System, ETWS), SIB7 includes secondary information of the ETWS, and SIB8 includes commercial mobile warning service (Commercial Mobile Alert Service, CMAS) information. In addition to SIB1, each SIB is transmitted in a corresponding transmission period, e.g., 80ms, 160ms, 320ms, etc., which may be configured and may be notified to the UE by the network device. The network device may transmit SIB composition SI messages (SI messages) of the same transmission period.

2. System information change

In general, an idle or inactive UE may periodically listen for paging messages (paging) according to a network device configuration. When the system information is changed, the network device may send an indication message for indicating the system information change to the UE, carried in paging downlink control information (paging Downlink Control Information, paging DCI), so as to notify the UE of the system information change. After the UE determines that the system information is changed, the UE may acquire the changed system information in the agreed receiving period. Typically, 2 bits (bits) are defined in the paging DCI to indicate system information changes, one bit to indicate other system information changes than SIB6 to SIB8, and another bit to indicate system information changes of SIB6 to SIB 8.

In the embodiment of the present invention, in general, when the ETWS information or CMAS information is not changed, the network device may use the bit position used for indicating SIB6 to SIB8 in the paging DCI as 0, so as to indicate that the content of SIB6 to SIB8 is not changed. When the ETWS information or CMAS information is changed, the network device may set a bit position in the paging DCI for indicating SIB6 to SIB8 to be 1, so as to indicate that the content of SIB6 to SIB8 is changed.

3. Network equipment corresponding to SIM card

The network device corresponding to one SIM card may refer to a set of network devices accessed by the UE that carries the SIM card. Specifically, the network devices corresponding to the plurality of SIM cards may refer to one set of network devices or a plurality of sets of network devices accessed by the UE that carries the plurality of SIM cards. For example, in the case where multiple SIM cards sign up for the same operator's network, the UE may access network devices in the same network where the multiple SIM cards sign up; in case of multiple SIM cards signing up for networks of different operators, the UE may access network devices in different networks of the multiple SIM card signing up.

According to the data transmission method and device provided by the embodiment of the invention, since the receiving priority of each data block is predefined, the network device sending the data block is configured through the system information or the downlink control signaling, or the network device sending the data block is indicated through the paging downlink control information or the paging information, when the receiving time periods of the M data blocks to be received by the UE are overlapped, the UE receives the data blocks according to the receiving priority (namely M receiving priorities) of the M data blocks, and the UE can be ensured to receive the data blocks with high receiving priority preferentially. Therefore, when network equipment in networks signed by different SIM cards sends downlink data to the UE in the same time period, the UE can be ensured to receive the data with higher receiving priority, so that the UE can be ensured to receive important data to a certain extent.

Wherein, the paging downlink control information may be paging downlink control information indicating that system information is changed; paging downlink control information for scheduling paging messages; the paging downlink control information may be paging control information that indicates that the system information is changed and that schedules the paging message. The method can be specifically determined according to actual use requirements, and the embodiment of the invention is not limited.

The technical scheme provided by the invention can be applied to various communication systems, such as a 5G communication system, a future evolution system, or various communication fusion systems and the like. Various application scenarios may be included, such as machine-to-machine (Machine to Machine, M2M), D2M, macro-micro communication, enhanced mobile internet (enhance Mobile Broadband, eMBB), ultra-high reliability and ultra-low latency communication (ultra-low latency & Low Latency Communication, uilllc), and mass internet of things communication (Massive Machine Type Communication, mctc). These scenarios include, but are not limited to: in the context of communication between UEs, or between a network device and a network device, or between a network device and a UE. The embodiment of the invention can be applied to communication between network equipment and UE in a 5G communication system, or communication between UE and UE, or communication between network equipment and network equipment.

Fig. 1 shows a schematic diagram of one possible architecture of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system includes at least one network device 100 (only one is illustrated in fig. 1) and one or more UEs 200 (only one is illustrated in fig. 1) to which each network device 100 is connected, one UE 200 may be connected to at least one network device 100, and one UE 200 may be mounted with at least 2 SIM cards.

The network device 100 may be a base station, a core network device, a transmitting and receiving node (Transmission and Reception Point, TRP), a relay station, an access point, or the like. The network device 100 may be a base transceiver station (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communication, GSM) or code division multiple access (Code Division Multiple Access, CDMA) network, an NB (NodeB) in wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), or an eNB or eNodeB (evolutional NodeB) in LTE. The network device 100 may also be a wireless controller in the context of a cloud wireless access network (Cloud Radio Access Network, CRAN). The network device 100 may also be a network device in a 5G communication system or a network device in a future evolution network. The words are not to be interpreted as limiting the invention.

UE 200 may be a wireless UE, which may be a device that provides voice and/or other traffic data connectivity to a user, a handheld device, computing device, or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a UE in a future 5G network, or a UE in a future evolved PLMN network, etc. The wireless UE may communicate with one or more core networks via a radio access network (Radio Access Network, RAN), which may be a Mobile UE, such as a Mobile phone (or "cellular" phone) and a computer with a Mobile UE, e.g., a portable, pocket, hand-held, computer-built-in or car-mounted Mobile device that exchanges voice and/or data with the radio access network, as well as personal communication service (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiation Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistant (Personal Digital Assistant, PDA) and the like, as well as Mobile devices, terminal devices, access Terminal devices, wireless communication devices, terminal device units, terminal device stations, mobile stations (Mobile stations), remote stations (Remote stations), remote Terminal devices (Remote terminals), subscriber units (Subscriber units), subscriber stations (Subscriber Station), user Agent devices, terminal Agent devices and the like. As an example, in the embodiment of the present invention, fig. 1 illustrates that the UE is a mobile phone.

The network device 100 and the UE 200 shown in fig. 1 will be described in detail in the following method embodiments and apparatus embodiments, which are not described herein.

The data transmission method according to the embodiment of the present invention is described below with reference to fig. 2. Fig. 2 is a flow chart of a data transmission method according to an embodiment of the present invention, and as shown in fig. 2, the data transmission method may include the following S201 and S202.

S201, at least one network device sends M data blocks to the UE.

Wherein a data block may correspond to one or a set of time-frequency resources on which the network device may transmit a data block. When a data block corresponds to a group of time-frequency resources, the network device can complete the initial transmission and retransmission of the data block on different time-frequency resources in the group of time-frequency resources, so as to improve the probability of correctly receiving the data.

Optionally, in the embodiment of the present invention, the at least one network device may be a network device in a network to which at least two SIM cards in the UE belong respectively.

For example, taking at least two SIM cards including the SIM card 1 and the SIM card 2 as an example, the network device in the network to which the SIM card 1 belongs and the network device in the network to which the SIM card 2 belongs may be the same network device (i.e., the SIM card 1 and the SIM card 2 are SIM cards subscribed to the same operator), or may be different network devices (i.e., the SIM card 1 and the SIM card 2 are SIM cards subscribed to different operators).

S202, in a case where reception periods for M data blocks overlap, the UE receives the target data block according to M reception priorities.

The target data block may be at least one data block of the M data blocks, where M is an integer greater than 1.

In the embodiment of the present invention, the M data blocks may be sent to the UE by at least one network device. Specifically, the M data blocks may be sent to the UE by at least one network device through M SIM cards, that is, each data block in the M data blocks may be sent to the UE by one network device through one SIM card.

In the embodiment of the invention, the UE only allows to receive one data block in M data blocks in one receiving time period. I.e. during the same reception period, the UE can only receive the data block sent by the network device through one SIM card.

In the embodiment of the present invention, the M receiving priorities are in one-to-one correspondence with the M data blocks, and the receiving priority of one data block is any one of the following: the predefined network device transmitting the one data block is configured through system information or downlink control signaling, and the network device transmitting the one data block is indicated through paging downlink control information (paging DCI) or paging message (paging message).

For example, the paging downlink control information may be transmitted through a physical downlink control channel (Physical Downlink control Channel, PDCCH). The paging message may be transmitted over a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).

Optionally, the overlapping of the receiving periods in the embodiment of the present invention may be that the receiving periods partially overlap, or may be that the receiving periods completely overlap.

The above-mentioned reception period may be, for example, a reception window. Specifically, the receiving time periods of the data blocks may overlap with each other, or the receiving windows of the data blocks may overlap with each other partially or entirely.

Optionally, in the embodiment of the present invention, in the case that the receiving priorities of the multiple data blocks in the M data blocks are the same, the UE may receive the multiple data blocks according to the sending time of the multiple data blocks, for example, the UE may preferentially receive the data block sent earliest in the multiple data blocks. If the reception priorities of the plurality of data blocks are the same and the transmission times of the plurality of data blocks are also the same, the UE may receive any one of the plurality of data blocks, for example, the UE may randomly receive any one of the plurality of data blocks.

Optionally, in an embodiment of the present invention, the M data blocks may include any one of the following: first class data blocks, first class data blocks and second class data blocks, first class data blocks and third class data blocks.

Wherein, each data block in the first type of data block can comprise ETWS information or CMAS information; each of the second class of data blocks may include a paging message; each data block in the third class of data blocks may include data transmitted on a target logical channel, which may include at least one of: logical channels corresponding to signaling radio bearers (Signalling Radio Bearer, SRB), logical channels corresponding to data radio bearers (Data Radio Bearer, DRB).

The M data blocks may specifically be any one of the following:

(1) The M data blocks include ETWS information.

(2) The M data blocks include CMAS information.

(3) The M data blocks include ETWS information and CMAS information.

(4) The M data blocks include ETWS information and paging messages.

(5) The M data blocks include CMAS information and paging messages.

(6) The M data blocks include ETWS information, CMAS information, and paging messages.

(7) The M data blocks comprise ETWS information and data transmitted on a logic channel corresponding to the SRB.

(8) The M data blocks comprise ETWS information and data transmitted on a logic channel corresponding to the DRB.

(9) The M data blocks include CMAS information and data transmitted on logical channels corresponding to SRBs.

(10) The M data blocks comprise CMAS information and data transmitted on a logical channel corresponding to the DRB.

(11) The M data blocks comprise ETWS information, CMAS information and data transmitted on a logic channel corresponding to the DRB.

(12) The M data blocks comprise ETWS information, CMAS information and data transmitted on a logic channel corresponding to the SRB.

(13) The M data blocks comprise ETWS information, data transmitted on a logical channel corresponding to the DRB and data transmitted on a logical channel corresponding to the SRB.

(14) The M data blocks comprise CMAS information, data transmitted on a logical channel corresponding to the DRB and data transmitted on a logical channel corresponding to the SRB.

(15) The M data blocks comprise ETWS information, CMAS information, data transmitted on a logic channel corresponding to the DRB and data transmitted on a logic channel corresponding to the SRB.

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

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

In the following, an example of the reception period for M data blocks including the reception period of CMAS information and the listening period of paging messages, and an example of the reception period for M data blocks including the reception period of ETWS information and the reception period of CMAS information are described with reference to fig. 3.

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

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

It should be noted that, in the above-listed M data in the embodiment of the present invention, since the importance degree/emergency degree of the ETWS information is generally the highest, the receiving priority of the ETWS information may be predefined to be the highest, or the network device may configure or indicate that the receiving priority of the ETWS information is the highest.

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

Optionally, in the embodiment of the present invention, the importance degree/urgency degree of the data block may be determined according to the content of the data block. It will be appreciated that in embodiments of the present invention, the importance/urgency of a data block representing the same or similar content may be the same, such that the predefined reception priority, network device configured or indicated reception priority may be the same. For data blocks of disparate content, representing their degree of importance/urgency, the predefined reception priority, network device configured or indicated reception priority may be disparate. Specifically, the following embodiments will be described in detail, and will not be described here.

For example, the receiving priorities of the ETWS information of different network device configurations may be the same, the receiving priorities of the CMAS information of different network device configurations may be the same, the receiving priorities of the paging messages of different network device configurations may be the same, the receiving priorities of the data blocks transmitted on the logical channels corresponding to the SRBs of different network device configurations may be the same, and the receiving priorities of the data blocks transmitted on the logical channels corresponding to the DRBs of different network device configurations may be the same.

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

Alternatively, in the embodiment of the present invention, because the content of the ETWS information and the CMAS information is similar, the reception priorities of the ETWS information and the CMAS information may be the same or different.

According to the data transmission method provided by the embodiment of the invention, since the receiving priority of each data block is predefined, the network equipment for transmitting the data block is configured through the system information or the downlink control signaling, or the network equipment for transmitting the data block is indicated through the paging downlink control information or the paging information, when the receiving time periods of the M data blocks to be received by the UE overlap, the UE receives the data blocks according to the receiving priorities (namely M receiving priorities) of the M data blocks, and the UE can be ensured to receive the data blocks with high receiving priorities preferentially. Therefore, when network equipment in networks signed by different SIM cards sends downlink data to the UE in the same time period, the UE can be ensured to receive the data with higher receiving priority, so that the UE can be ensured to receive important data to a certain extent.

Optionally, in the data transmission method provided in the embodiment of the present invention, S202 may be specifically implemented through S202a, S202b, or S202c described below.

S202a, in a case where reception periods for M data overlap, the UE receives the first data block, and the reception priority of the first data block is lower than that of the second data block, the UE stops receiving the first data block, and starts 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 M data blocks, and the sending time of the first data block is earlier than the sending time of the second data block. That is, the UE is receiving the first data block, the network device sends the second data block to the UE, and the UE can only receive one data block of the M data blocks in a reception period, and if the reception priority of the first data block is lower than the reception priority of the second data block, the UE can stop receiving the first data block and start receiving the second data block.

Optionally, in the embodiment of the present invention, the UE may start to receive the second data block at the start time of the receiving period of the second data block, and the UE may also start to receive the second data block at the time of stopping to receive the first data block.

In the embodiment of the present invention, the UE stopping receiving the first data block may suspend receiving the first data block for the UE, and the UE may wait for the reception of the data block with the high reception priority to be completed, and then continue to receive or re-receive the first data block; the UE may stop receiving the first data block, or cancel receiving the first data block for the UE, and the UE may discard a part of data in the received first data block.

In the embodiment of the invention, if the receiving time periods of the plurality of 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, because the receiving priority of the second data block is higher than that of the first data block, the second data block is more important than the first data block, the UE stops receiving the first data block and starts to receive the second data block, so that more important data is preferentially received, and missing important data of the UE is avoided.

S202b, when the reception periods for the M data blocks overlap, the UE receives the third data block according to the M reception priorities, and discards receiving the fourth data block.

The third data block is the data block with the highest receiving priority in the M data blocks, and the fourth data block is the data block except the third data block in the M data blocks.

It should be noted that, in the 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 a plurality of data blocks with the same receiving priority, and then the UE may receive the data block with the earliest sending time according to the sending time of the plurality of data blocks.

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

In the embodiment of the invention, under the condition that the receiving time periods of the M data blocks overlap, the UE can receive the third data block with the highest receiving priority according to the receiving priority (namely M receiving priorities) of the M data blocks and discard to receive the data blocks except the third data block in the M data blocks, so that the UE can be ensured to receive the data with the highest receiving priority, and the UE can be ensured to receive important data to a certain extent.

S202c, when the reception periods for the M data blocks overlap, the UE sequentially receives at least two data blocks from the M data blocks in order of the M reception priorities from high to low according to the M reception priorities.

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

It is understood that the UE may receive the top N data blocks of the priority rank in order of priority from high to low, N being an integer greater than or equal to 2 and less than or equal to M.

In the embodiment of the invention, when the receiving time periods of the M data blocks overlap, the UE can sequentially receive at least two data blocks in the M data blocks according to the M receiving priorities corresponding to the M data blocks one by one and the order of the M receiving priorities from top to bottom, and when the first several data blocks with higher priority are important, the UE can receive the data block with the highest priority and then receive the data block with the highest priority, so that the situation that the important data are received by the UE when the receiving time periods of the data blocks overlap can be avoided, and the UE can select more receiving modes to receive the data block when the receiving time periods of the data blocks overlap.

Optionally, as shown in fig. 4, in the data transmission method provided in the embodiment of the present invention, S203 described below may be further included before S201.

S203, the UE acquires M receiving priorities.

Wherein the M priorities may be predefined, or configured for the network device to be UE, or indicated for the network device to be UE.

In the embodiment of the present invention, the content of the M data blocks is different, and the manner in which the UE obtains the reception priority (i.e., the reception priority of the M data blocks) is different. The manner in which the UE obtains the reception priority when the M data blocks include the first class data block, the second class data block, or the third class data block, respectively, is described as follows.

First case: the M data blocks comprise a first type data block

Optionally, in the data transmission method provided in the embodiment of the present invention, in a case where the M data blocks include a first type of data block, S203 may be specifically implemented through S203a described below.

And S203a, the UE acquires the receiving priority of the first type data block.

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

It will be appreciated that the first network device may send the first paging downlink control information to the UE, or the first paging message to the UE, or the first system information to the UE, before sending the first type of data block, to indicate the reception priority of the UE first type of data block.

For example, the UE may acquire reception priority of the ETWS information or CMAS information through paging the downlink control information; or, the UE can acquire the receiving priority of the ETWS information or the CMAS information through the paging message; alternatively, the UE may acquire reception priority of the ETWS information or CMAS information through SIB 1.

It should be noted that, if the M data blocks include a plurality of first type data blocks, the plurality of 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 comprises first indication information, the first indication information is used for indicating that the content of the first type of data block changes, and the second paging downlink control information is downlink control information for scheduling the first paging message.

For example, when an earthquake or tsunami occurs, the content of the ETWS information changes, the first network device may send first paging downlink control information to the UE, where the first paging downlink control information may carry a reception priority 1 and indicate that the content of the ETWS information changes, where the reception priority 1 is a reception priority of the content of the ETWS information received by the UE, and after receiving the first paging downlink control information, the UE may obtain the reception priority 1 through the first paging downlink control information, and then receive the ETWS information in a reception period of the ETWS information based on the reception priority 1 by the UE.

Based on the scheme, the network device can send the first paging downlink control information indicating the content of the first type data block to the UE under the condition that the content of the first type data block is changed, wherein the first paging downlink control information carries the receiving priority of the first type data block with the changed content, so that the UE can acquire the receiving priority of the first type data block through the first paging downlink control information or the first paging message, and the UE can preferentially receive the data block with higher priority under the condition that the receiving time periods of the received data are overlapped.

Optionally, the receiving priority of the first type of data block may be configured by the first network device through the first system information; in the data transmission method provided in the embodiment of the present invention, S203a described above may be specifically implemented by S203a1 described below.

And S203a1, under the condition that third paging downlink control information sent by the first network equipment is received, the UE acquires the receiving priority of the first type data block.

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 data block changes.

For example, when the UE receives third paging downlink control information sent by the network device, where the third paging downlink control information carries information indicating that the content of the ETWS information or the CMAS information is changed, the UE may read the reception priority of the ETWS information or the reception priority of the CMAS information after the content is changed, which is configured in SIB1 sent by the network device.

It can be appreciated that in the case that the UE does not receive the third paging downlink control information, that is, the content of the first type data block is not changed, the UE does not need to receive the first type data block, and therefore, the UE does not need to acquire the reception priority of the first type data block.

In the embodiment of the invention, after receiving the third paging downlink control information sent by the network equipment, the UE can quickly determine that the content of the first type data block changes according to the third paging downlink control information, and then acquire the receiving priority of the first type data block through the first system information, so that the UE can receive the data with higher importance or higher emergency degree preferentially according to the receiving priority acquired in the first system information.

Second case: the M data blocks comprise the second type data block

Optionally, in the data transmission method provided by the embodiment of the present invention, where the M data blocks include the second class data block, S203 may be specifically implemented through S203b described below.

And S203b, the UE acquires the receiving priority of the second class data block.

Wherein the receiving priority of the second class data block is predefined, or the second network device (which is the network device in the at least one network device) is configured through the second system information, and the second network device is the network device that sends the second class data block.

Optionally, in the embodiment of the present invention, different second class data blocks in the M data blocks may be sent by different network devices, or may be sent by the same network device.

It should be noted that the UE may determine the priority of the second class of data blocks according to the protocol specification (i.e. predefined).

Third case: the M data blocks comprise data blocks of a third type

Optionally, in the data transmission method provided in the embodiment of the present invention, in a case where the M data blocks include a third type of data block, S203 described above may be specifically implemented through S203c described below.

And S203c, the UE acquires the receiving priority of the third class data block.

Wherein the receiving priority of the third class of data block may be predefined (e.g. specified by a protocol), or may be configured by the first downlink control signaling for a third network device (being a network device of the at least one network device) that is a network device that transmits the third class of data block; the first downlink control signaling may include a reception priority of the third type of data block, or may include a quality of service requirement of the target logical channel for the UE to determine the reception priority of the third type of data block.

Optionally, in an embodiment of the present invention, the third data block may include at least one of data transmitted on a logical channel corresponding to the SRB and data transmitted on a logical channel corresponding to the DRB.

Optionally, in the embodiment of the present invention, the service quality requirement carried in the first downlink control signaling may be a service quality (Quality of Service, qoS) or a 5G QoS identifier (5G QoS Identifier,5QI). The UE may query, through QOS or 5QI, a correspondence between the service quality requirement and the reception priority stored in the UE, to obtain the reception priority of the third class of data block.

Specifically, the first downlink control signaling may be radio resource control (Radio Resource Control, RRC) signaling.

When the UE receives the third class data block, the third class data block may include a plurality of service data (i.e., a plurality of logical channels), and the UE may use a reception priority with the highest reception priority among the plurality of service data as the reception priority of the third data block.

In the embodiment of the invention, the UE can acquire the priorities of different types of data in different manners, and in the case that the M data blocks include the first type of data blocks, the UE can acquire the receiving priority of the first type of data blocks from the first paging information passed by the first network device, or the UE can acquire the receiving priority of the first type of data blocks from the first system information sent by the first network device. In the case that the M data blocks include the second class data block, the UE may acquire a reception priority of the second class data block through a predefined priority, and the UE may also acquire the reception priority of the second class data block from second system information sent by the second network device; in the case that the M data blocks include the third class data block, the UE may acquire the receiving priority of the third class data block according to the predefined receiving priority of the third class data block or according to the third class network device through the first downlink control signaling, so that the UE may flexibly and accurately acquire the receiving priority of each data block in the M data blocks by adopting different acquiring manners.

In the embodiment of the present invention, the above three cases are respectively exemplified by the case that the M data blocks include one type of data block (for example, include a first type of data block, a second type of data block, or a third type of data block), and the method for acquiring the reception priority of each data block is described in an exemplary manner.

It should be noted that, in the embodiment of the present invention, the above description of the classification of the M data blocks is only for clearly describing the manner of obtaining the reception priority of the data blocks, which is not limited in any way. Specifically, the receiving priority of each type of data block in the M data blocks is obtained in different manners, for example, the receiving priority of the first type of data block may be obtained through paging message or system information; the receiving priority of the second class data block can be obtained through predefined information or system information; the receiving priority of the third class data block can be obtained through predefined information or downlink control signaling. It can be understood that the receiving priority of each data block in each class of data blocks is obtained in the same manner, for example, the receiving priority of each data block in the first class of data blocks is obtained in the same manner, the receiving priority of each data block in the second class of data blocks is obtained in the same manner, and the receiving priority of each data block in the third class of data blocks is obtained in the same manner.

Optionally, in the case where the reception priority of the M data blocks is configured or indicated by the network device for the UE, in the embodiment of the present invention, before the UE obtains the M reception priorities of the M data blocks, the network device (i.e. at least one network device described above) configures or indicates the reception priority of the M data blocks for the UE. The method in which one network device configures or indicates the reception priority of one data block (for example, a first target data block described below) among M data blocks for the UE will be described below as an example.

Optionally, as shown in fig. 5, in the data transmission method provided in the embodiment of the present invention, S204 described below may be further included before S203.

S204, the network device configures or indicates, for the UE, a reception priority of the first target data block to be transmitted.

The receiving priority of the first target data block may be configured through system information or downlink control signaling, or the receiving priority of the first target data block may be indicated through a paging message. The reception priority of the first target data block may be used for the UE to receive the data blocks with overlapping reception periods for M data blocks, M being an integer greater than 1, including the first target data block.

Optionally, the first target data block includes any one of the following: ETWS information, CMAS information, paging messages, data transmitted on the target logical channel.

Wherein the target logical channel may comprise at least one of: logical channels corresponding to SRB and logical channels corresponding to DRB.

According to the data transmission method provided by the embodiment of the invention, the network equipment can configure or indicate the receiving priority of the first target data block to be transmitted for the UE, and can configure the receiving priority of the first target data through the system information or through the downlink control signaling, so that the UE can receive the data block by combining the receiving priority under the condition that the receiving time periods of the M data blocks overlap, and therefore important data can be prevented from being missed when the UE receives the data.

In the embodiment of the present invention, the manner in which the network device configures or indicates the reception priority (i.e., the reception priority of M data blocks) for the UE may be different for the data blocks of different contents. The following describes exemplary ways in which the network device configures or indicates the reception priority for the UE when the first target data block includes the ETWS information, CMAS information, paging information, or data transmitted on the target logical channel, respectively.

The first way is: the first target data block comprises ETWS information or CMAS information

Optionally, in the case that the first target data block includes the ETWS information or the CMAS information, S204 in the data transmission method provided in the embodiment of the present invention may be specifically implemented through S204a, S204b, or S204 c.

And S204a, the network equipment indicates the receiving priority of the first target data block to the UE through the first paging downlink control information.

For example, with the first target data as the ETWS information, before the network device sends the ETWS information to the UE, the paging DCI transmitted through the PDCCH may indicate the reception priority of the ETWS information to the UE, and the paging DCI may also indicate the resource for sending the paging message.

And S204b, the network equipment indicates the receiving priority of the first target data block to the UE through the first paging message.

For example, before sending the ETWS information to the UE, the network device may indicate the reception priority of the ETWS information to the UE through a paging message, and before sending the CMAS information, the network device may also indicate the reception priority of the CMAS information to the UE through the paging message. Of course, the network device may carry the reception priority of both the ETWS information and the CMAS information in the paging message.

Alternatively, the first paging message may be one of paging messages sent by the network device in a paging cycle, or may be a paging message sent immediately, which is not limited in particular in the embodiment of the present invention.

In the embodiment of the present invention, when the first target data block includes the ETWS information or the CMAS information, the network device may indicate, to the UE, the reception priority of the first target data block through the first paging message, so that the UE may acquire, through the first paging message, the reception priority of the first target data block.

Optionally, the first paging downlink control information or the second paging downlink control information includes first indication information, where the first indication information is used to indicate that the content of the first target data block changes, and the second paging downlink control information is downlink control information for scheduling the first paging message.

For example, in case that the content of the ETWS information is changed, the network device may carry the reception priority of the content-changed ETWS information in a paging message indicating the content change of the ETWS information, and transmit the paging message to the UE.

In the embodiment of the invention, the network equipment can carry the receiving priority indicating the first target data block in the paging message indicating the content of the first target data block to be changed, and the receiving priority of the first target data block can be sent without using a paging message additionally, thereby avoiding the waste of paging resources.

S204c, the network equipment configures the receiving priority of the first target data block for the UE through the first system information.

For example, the network device may carry the reception priority of the first target data block in SIB1 and transmit SIB1 carrying the reception priority of the first target data block to the UE in a transmission period of SIB1.

Specifically, in the data transmission method provided in the embodiment of the present invention, the above S204c may be specifically implemented by the following S204c 1.

S204c1, when the content of the first target data block changes, the network device configures, for the UE, a reception priority of the first target data block according to the first system information.

It should be noted that, because the change of the content of the ETWS information or the CMAS information may indicate that there is an earthquake, tsunami, or the like, the network device needs to prompt, through the UE, to the user that the ETWS information or the CMAS information has changed in time, so that, in the case that the content of the first target data block changes, the network device may configure, through the first system information, the receiving priority of the first target data block for the UE.

In the embodiment of the invention, the network device can configure the receiving priority of the first target data block for the UE through the first system information under the condition that the content of the first target data block is changed.

The second way is: the first target data block includes a paging message

Optionally, in the embodiment of the present invention, in the case that the first target data block includes the paging message, the data transmission method provided in the embodiment of the present invention, S204 may be specifically implemented through S204d described below.

S204d, the network equipment configures the receiving priority of the first target data block for the UE through the second system information.

For example, the network device may notify the receiving priority of the paging message of the UE in the coverage area by broadcasting a system message, and after the UE enters the coverage area of one network device, the UE may acquire the receiving priority of the paging message by using system information broadcasted by the network device, where the system information may include configuration information such as a receiving time and a receiving priority of the paging message.

Of course, if the network device needs to reconfigure the reception priority of the paging message, the network device may carry the reception priority of the reselection configuration in the second system information.

In the embodiment of the invention, if the network equipment needs to send the paging message to the UE, the network equipment can configure the receiving priority of the paging message for the UE through the second system information.

Third mode: the first target data block includes data transmitted on a target logical channel

Optionally, in the embodiment of the present invention, in the case that the first target data block includes data transmitted on the target logical channel, the data transmission method provided in the embodiment of the present invention, S204 may be specifically implemented through S204e described below.

S204e, the network equipment configures the receiving priority of the first target data block for the UE through the first downlink control signaling.

The first downlink control signaling may include a reception priority of the first target data block, or may include a quality of service requirement of a target logical channel, which may be used by the UE to determine the reception priority of the first target data block.

For example, the first downlink control signaling may be RRC signaling. The network device may configure the reception priority of the first target data block for the UE through RRC signaling in case of establishing the RRC connection.

In the embodiment of the present invention, when the UE requests the network device to send service data, the network device sends the service requested by the UE to the core network device, and the core network device may determine a service quality requirement for the service requested by the UE and send the service quality requirement to the network device (e.g., an access network device to which the UE is connected), where the network device may send the service quality requirement to the UE through a downlink control signaling, and the network device may also query a receiving priority corresponding to the service quality requirement according to the service quality requirement, and then send a priority corresponding to the service instruction requirement to the UE through a downlink control signaling.

It should be noted that, in the embodiment of the present invention, if the UE requests multiple services, the network device may configure, for the UE, the reception priority of the data block transmitted on multiple logical channels when the service data is transmitted to the UE on the multiple logical channels. Wherein, the services are different, and the receiving priority of the data blocks of the corresponding services can be the same or different.

In the embodiment of the present invention, the network device may configure or indicate the reception priority for the UE in different manners when the first target data block includes different contents. For example, in the case that the first target data block includes the ETWS information or the CMAS information, the network device indicates the reception priority of the first target data block for the UE through the first paging downlink control information or the first paging message, and the network device may also configure the reception priority of the first target data block for the UE through the first system information; in the case that the first target data block includes a paging message, the network device may configure the UE with a reception priority of the first target data block through the second system information; in the case that the first target data block includes data transmitted on the target logical channel, the network device may configure the reception priority of the data block transmitted on the target logical channel for the UE through the first downlink control signaling. Therefore, the network equipment can flexibly configure or indicate the receiving priority for the data blocks to be sent in different modes according to different data, and the configuration or indication of the receiving priority can be more flexible and accurate.

In the embodiment of the present invention, the above three cases are respectively exemplified by one data block (for example, including the ETWS information or the CMAS information, the paging message, and the data block transmitted on the target logical channel), and the configuration or indication method of the receiving priority of each of the M data blocks by the network device is exemplified.
