The present application provides a transmission conflict solving method and apparatus, a terminal, and a storage medium, belonging to the field of mobile communications. The method comprises: selecting, according to a first criterion, one of the first uplink transmission and the second uplink transmission for transmission. As the first criterion is not a criterion implemented by UE itself, it can be avoided that, due to a difference in the criterion implemented by each UE itself, the UE itself may select an uplink transmission having a lower priority for transmission, thereby ensuring a transmission delay of the uplink transmission containing a first MAC CE or a first MAC SDU, and satisfying delay requirements of a service in an IIoT scenario.

Detailed ways

In order to make the objectives, technical solutions, and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below with reference to the accompanying drawings.

First, a brief introduction is made to the relevant content involved in the embodiments of the present application.

IIoT scenario: The 5G (Fifth Generation) IIoT scenario needs to support the transmission of services such as Industrial Automation (Factory Automation), Transport Industry (Transport Industry), and Intelligent Power (Electrical Power Distribution) in the 5G system. It has higher requirements for data transmission delay and reliability.

LCP: (Logical Channel prioritization, logical channel priority), when UE (User Equipment) acquires uplink resources for new transmission, data transmission is performed according to the priority of the logical channel. When the UE performs the priority processing of the logical channel, it follows the following priority order (arranged in the order of priority from high to low), and is divided into 7 categories:

1) C-RNTI (Cell Radio Network Temporary Identity) MAC (Media Access Control) CE (Control Unit) or UL-CCCH (Uplink Common Control Channel), uplink common control Channel) data;

2) Configured Grant Confirmation MAC CE;

3) MAC CE of non-filled BSR (Buffer Status Report);

4) Single entry power headroom report (Single Entry PHR) MAC CE or multiple entry power headroom report (Multiple Entry PHR) MAC CE;

5) Data of any logical channel except UL-CCCH;

6) MAC CE of Recommended Bit Rate Query;

7) Fill the MAC CE of the BSR.

RA: (Random Access) includes CBRA (Contention-Based Random Access, contention-based random access) and CFRA (Contention Free Random Access, non-competition-based random access). Among them, CBRA usually includes the following four steps: (1) the UE sends msg1 to the network device; (2) the network device sends msg2 to the UE based on msg1 (also known as RAR (Random Access Response)); 3) The UE sends msg3 to the network device based on msg2; (4) The network device sends msg4 to the UE based on msg3. In this way, it is necessary to determine whether the UE can successfully access the network by means of competition. Among them, CFRA usually includes the following three steps: (1) The network device sends msg0 to the UE to configure dedicated resources for the UE; (2) The UE sends msg1 to the network device based on msg0, which is equivalent to initiating a random access request to the network device ; (3) The network device sends msg2 (namely RAR) to the UE based on msg1. In CFRA, because resources such as preamble (preamble) are dedicated to the UE by network equipment, the UE uses dedicated resources to initiate RA access to the network, avoiding the need for the UE and other UEs to perform resource competition judgments.

In the foregoing implementation process, when the UE sends msg1, that is, after sending the preamble, the RAR monitoring window is opened to monitor PDCCH (Physical Downlink Control Channel) to obtain msg2 (RAR). For CBRA, when the UE determines that the C-RNTI used to scramble the PDCCH matches its own C-RNTI, it carries the C-RNTI MAC CE or CCCH (Common Control Channel) SDU ( Service Data Unit, service data unit).

There are several reasons for triggering RA:

1) Initial access to the network;

2) RRC (Radio Resource Control, radio resource control) connection re-establishment;

3) The downlink data arrives, but the uplink is out of synchronization;

4) The uplink data arrives, but the uplink is out of synchronization or there is no uplink resource;

5) SR (Scheduling Request) has no corresponding transmission resources;

6) Switch;

7) BFR (Beam Failure Recovery, beam failure recovery);

8) Request other system information;

9) Transition from the RRC-INACTIVE (inactive) state to the connected state.

Among them, the above 3), 4), 5), 6) and 7) are the trigger events of the connected RA.

The information carried in the UL grant (Uplink Scheduling grant) received by the UE may be: only MAC CE, or only MAC SDU, or both MAC CE and MAC SDU. When a grant conflicts with another grant, or the grant conflicts with UCI, or the grant conflicts with the PUCCH used to carry UCI, how to determine which uplink transmission (involving MAC CE) needs priority transmission? solved problem. To this end, the embodiments of the present application provide a method for solving transmission conflicts. When a conflict occurs between two uplink transmissions involving MAC CE, the method can give priority to the problem of how to transmit one of the uplink transmissions. The specific implementation is as follows As stated in the text.

Next, the implementation environment involved in the embodiments of the present application will be briefly introduced.

Referring to Fig. 1, Fig. 1 is a schematic diagram showing an implementation environment according to an exemplary embodiment. The implementation environment includes at least one terminal 110 and a network device 120. FIG. 1 uses a terminal as an example for illustration. The terminal 110 and the network device 120 can communicate data through a communication network. The terminal 110 and the network device 120 are both equipped with a MAC entity, so as to realize the data transmission of the MAC layer through the MAC entity, that is, in the embodiment of the present application, the terminal may realize the data transmission method through the MAC entity. As an example, the terminal 110 may be a device that can be used for data communication such as a mobile phone, a tablet computer, or an industrial sensor, such as a UE in the IIoT. In addition, the network device may be a network side device such as a base station, an access network device, or a core network device.

If there are multiple terminals 110, the two terminals 110 may also communicate directly through a side link (Sidelink, SL).

Referring to FIG. 2, FIG. 2 is a flowchart showing a method for resolving transmission conflicts according to an exemplary embodiment of the present application. In this embodiment, the method is applied to the user equipment UE of the Industrial Internet of Things (IIoT) as an example. The method includes:

Step 202: When the first uplink transmission and the second uplink transmission collide, one of the first uplink transmission and the second uplink transmission is selected for transmission according to the first criterion.

Optionally, the first criterion is a criterion predefined by the communication protocol, rather than a criterion implemented by the UE itself.

Optionally, the first uplink transmission is an uplink transmission scheduled by the first Grant, and the second uplink transmission is an uplink transmission scheduled by the second Grant. The first Grant can be dynamic scheduling (Dynamic Grant, DG) or semi-static scheduling (Configuration Grant, CG); the second grant can be dynamic scheduling (Dynamic Grant, DG) or semi-static scheduling (Configuration Grant) , CG).

In some embodiments, the first uplink transmission is a transmission used to transmit data, and the second uplink transmission is a transmission used to transmit data. At this time, there is a conflict between "data" and "data" between the two uplink transmissions. .

In some embodiments, the first uplink transmission is used to transmit at least MAC CE, and the second uplink transmission is used to transmit data. At this time, the two uplink transmissions are at least MAC CE and data. Conflict between.

In some embodiments, the first uplink transmission is used to transmit at least MAC CE, and the second uplink transmission is used to transmit at least MAC CE. In this case, the two uplink transmissions are at least MAC CE and "At least MAC CE". At least MAC CE" conflicts. In some embodiments, the first uplink transmission is used to transmit data, and the second uplink transmission is used to transmit control information. At this time, the two uplink transmissions are between "data" and "control information". Conflict. Control information can be understood as a control channel or uplink control information (Uplink Control Information, UCI).

The first uplink transmission is a transmission used to transmit control information, and the second uplink transmission is a transmission used to transmit control information. At this time, there is a conflict between "control information" and "control information" between the two uplink transmissions.

The conflict between the first uplink transmission and the second uplink transmission means that the transmission resource carrying the first uplink transmission and the transmission resource carrying the second uplink transmission completely overlap or partially overlap in the time domain.

Optionally, the first criterion includes at least one of the following types of criteria:

-The uplink transmission carrying the first MAC CE or the first MAC SDU is transmitted preferentially;

-The uplink transmission that carries explicit information with higher priority is preferentially transmitted. The explicit information can be at least one of the LCH and/or MAC CE transmitted in the uplink transmission; or in the uplink transmission that carries the display information , The uplink transmission corresponding to the higher priority display information is transmitted first;

-According to the order of the category priority, it is determined that the uplink transmission with the higher category priority is transmitted first.

-According to the LCP priority, it is determined that the upstream transmission with higher priority is transmitted first.

In summary, the method provided in this embodiment selects one of the first uplink transmission and the second uplink transmission for transmission according to the first criterion when the first uplink transmission and the second uplink transmission collide. The criterion is not a criterion implemented by the UE itself. Therefore, it can be avoided that due to differences in the criterion implemented by each UE, the UE may select a lower priority uplink transmission for transmission by itself, thereby ensuring the higher priority uplink transmission. Transmission delay meets the delay requirements of services in the IIoT scenario.

For a possible implementation of the first criterion, the following embodiments are provided:

When the first uplink transmission and the second uplink transmission conflict, the UE selects the first uplink transmission and the second uplink transmission, which includes the first MAC CE or the specific MAC SDU, for transmission.

Among them, the first MAC CE includes at least one of the following MAC CEs:

MAC CE with priority not less than PUSCH priority;

MAC CE with specific priority;

MAC CE with a specific purpose;

MAC CE with a specific trigger reason;

MAC CE with a priority higher than the threshold.

Among them, the specific MAC SDU is the MAC SDU corresponding to the specific logical channel. A specific logical channel refers to a logical channel configured or designated by the network, or a logical channel predefined by a communication protocol.

"Specific" in this document can be understood as network configuration or designation, or pre-defined by the communication protocol. The “specific” can also be understood as meaning: specific LCH priority, specific LCH identifier, specific service transmission, etc., which is not limited in this application.

The aforementioned "threshold" may be configured by RRC (Radio Resource Control, radio resource control), or pre-defined, or indicated by DCI (Downlink Control Information, downlink control information).

In an example, the MAC CE with a specific priority includes at least one of the following MAC CEs: a MAC CE with a specific priority identifier; and a MAC CE with a specific value.

For example, the MAC CE with the highest priority identifier, the MAC CE with the priority value of 00, etc., are not limited in this application.

In an example, a MAC CE with a specific purpose includes at least one of the following MAC CEs: Confirmation MAC CE; CCCH SDU; C-RNTI; BSR MAC CE; PHR MAC CE.

In one example, the MAC CE with a specific trigger reason includes at least one of the following MAC CEs:

BFR RA;

Used to confirm the MAC CE triggered by the activation or deactivation of the authorized CG;

Used to confirm the MAC CE triggered by the activation or deactivation of the CG corresponding to the URLLC service;

Used to confirm the MAC CE triggered by the activation or deactivation of the CG corresponding to the URLLC logical channel;

Used to report MAC CE triggered by BSR;

Used to report the MAC CE triggered by the activation or deactivation of the BSR corresponding to the URLLC service;

Used to report the MAC CE triggered by the activation or deactivation of the BSR corresponding to the URLLC logical channel;

PHR MAC CE triggered by path loss change;

PHR MAC CE triggered by the timeout of the PHR cycle timer;

The primary and secondary cell (Master Secondary Cell, PScell) adds the triggered PHR MAC CE.

Figure 3 takes the application of this embodiment in the "CG" vs. "DG" conflict scenario as an example, that is, the first uplink transmission is CG-scheduled uplink transmission, and the second uplink transmission is DG-scheduled uplink transmission as an example, but this embodiment It can also be applied to other conflict scenarios such as "CG" vs "CG", "DG" vs "DG", "Data" vs "UCI", "UCI" vs "UCI". The transmission resource scheduled by the CG may be a configuration resource on the uplink (Uplink) or a configuration resource on the side link (SideLink, SL).

Fig. 3 shows a flowchart of a method for resolving transmission conflicts provided by an exemplary embodiment of the present application. The method includes:

Step 301: The UE receives a semi-persistent scheduling grant, where the semi-persistent scheduling grant is used to schedule the first uplink transmission on the CG resource;

This semi-persistent scheduling authorization is also called CG configuration. The semi-persistent scheduling grant is used to configure the first uplink transmission on transmission resources that appear periodically.

Step 302: The UE receives DCI, where the DCI is used to schedule a second uplink transmission on the DG resource.

The DCI is used for dynamic scheduling. The dynamic scheduling is used to configure the second uplink transmission on the transmission resource dynamically configured this time.

Step 303: When the CG resource and the DG resource conflict in the time domain, select the first uplink transmission and the second uplink transmission, including the first MAC CE or the first MAC SDU uplink transmission for transmission.

With reference to FIG. 4, when the first uplink transmission includes the first MAC CE (or the first MAC SDU) and the second uplink transmission does not include the first MAC CE (or the first MAC SDU), the first uplink transmission is preferentially transmitted.

When the first uplink transmission does not include the first MAC CE (or the first MAC SDU) and the second uplink transmission includes the first MAC CE (or the first MAC SDU), the second uplink transmission is preferentially transmitted.

When both the first uplink transmission and the second uplink transmission include the first MAC CE (or the first MAC SDU), according to the second criterion, one of the first uplink transmission and the second uplink transmission is selected for priority transmission.

For example, if the UE determines that the first uplink transmission includes the C-RNTI MAC CE, and the second uplink transmission does not include the first MAC CE, the UE determines to transmit the first uplink transmission first.

For another example, if the UE determines that the first uplink transmission includes data (or MAC SDU) of the logical channel of URLLC, and the second uplink transmission does not include the first MAC SDU, the UE determines to transmit the first uplink transmission first.

In summary, the method provided in this embodiment selects one of the first uplink transmission and the second uplink transmission for transmission according to the first criterion when the first uplink transmission and the second uplink transmission collide. The criteria are not implemented by the UE itself. Therefore, it can be avoided that due to the differences in the criteria implemented by each UE, the UE may select a lower priority uplink transmission for transmission, thereby ensuring that the first MAC CE or the first MAC is included. The transmission delay of the uplink transmission of the MAC SDU meets the delay requirements of the service in the IIoT scenario.

Based on the embodiment shown in FIG. 3, in an optional embodiment, selecting one of the first uplink transmission and the second uplink transmission for priority transmission according to the second criterion includes:

If both CG and DG contain the data of the first MAC CE or the first logical channel (or MAC SDU), the conflicting resources or information determined by the UE have the same priority, or it is determined that no resource meets the above conditions (that is, both This condition), then which of the first uplink transmission and the second uplink transmission is transmitted first depends on:

1), UE implementation;

That is, the second criterion implemented by the UE itself is built-in by the manufacturer or supplier of the UE when the UE leaves the factory, and the UE implementation of different manufacturers or suppliers may be different.

When the UE implements it by itself, it can choose one of the two uplink transmissions, or choose the uplink transmission with the start time earlier, or the uplink transmission with the start time later, or choose the end time earlier or later. For uplink transmission, either PUSCH, or PUCCH, or PUSCH carrying UCI, etc. are selected, which is not limited in the embodiment of the present application.

2) The priority of PUCCH or PUSCH resources;

In this embodiment, it refers to the priority of the two PUSCH resources corresponding to the first uplink transmission and the second uplink transmission.

3) Priority of MAC CE;

The MAC CE with the highest priority among the multiple MAC CEs included in the two uplink transmissions (or transmission resources), or the highest priority MAC CE among the first MAC CE included in the two resources MAC CE.

4) Priority transmission of DG;

5) The second highest priority LCH.

For another possible implementation of the first criterion, the following embodiments are provided:

When the first uplink transmission and the second uplink transmission conflict, the UE selects the uplink transmission corresponding to the explicit information with higher priority among the first explicit information and the second explicit information for transmission;

The first explicit information is the LCH and/or MAC CE corresponding to the first uplink transmission, and the second explicit information is the LCH and/or MAC CE corresponding to the second uplink transmission.

The first explicit information is preconfigured or predefined or configured on the network side or indicated by the network side; the second explicit information is preconfigured or predefined or configured on the network side or indicated by the network side.

In an example, the first uplink transmission corresponds to LCH1 and the second uplink transmission corresponds to LCH2. When the priority of LCH1 is higher than the priority of LCH2, the first uplink transmission is transmitted first; when the priority of LCH1 is lower than the priority of LCH2, Prioritize the second uplink transmission.

In another example, the first uplink transmission corresponds to LCH1 and the second uplink transmission corresponds to MAC CE2. When the priority of LCH1 is higher than the priority of MAC CE2, the first uplink transmission is transmitted first; the priority of LCH1 is lower than that of MAC CE2. In the case of priority, the second uplink transmission is transmitted first.

In an example, the first uplink transmission corresponds to MAC CE1, and the second uplink transmission corresponds to MAC CE2. When the priority of MAC CE1 is higher than the priority of MAC CE2, the first uplink transmission is transmitted first; MAC CE1 has a lower priority than MAC When the priority of CE2 is set, the second uplink transmission is transmitted first.

Fig. 5 takes the application of this embodiment in a "data" vs. "PDCCH" conflict scenario as an example, but this embodiment can also be applied to other conflict scenarios such as "data" vs. "data". The transmission resource for transmitting data may be a configuration resource on the uplink (Uplink) or a configuration resource on the side link (SideLink, SL).

FIG. 5 shows a flowchart of a method for resolving transmission conflicts according to another exemplary embodiment of the present application. The method includes:

Step 501: The UE receives a semi-persistent scheduling grant, where the semi-persistent scheduling grant is used to schedule the first uplink transmission on the CG resource;

This semi-persistent scheduling authorization is also called CG configuration. The semi-persistent scheduling grant is used to configure the first uplink transmission on transmission resources that appear periodically. For example, the first uplink transmission is performed on the PUSCH resource starting at time t1.

Step 502: The UE receives DCI, which is used to schedule the second uplink transmission on the DG resource.

The DCI is used for dynamic scheduling. The dynamic scheduling is used to configure the second uplink transmission on the transmission resource dynamically configured this time. For example, the HARQ-ACK is fed back to the base station on the PUCCH resource starting at time t1. Therefore, PUSCH resources and PUCCH resources conflict.

Step 503: When the CG resource and the DG resource conflict in the time domain, the UE selects the first explicit information and the second explicit information, the uplink transmission corresponding to the explicit information with a higher priority for transmission;

The first criterion includes: Prioritize transmission of uplink transmissions containing higher priority explicit information. Specifically, for at least one LCH and at least one MAC CE, the network side configures the priority value or indication, or the network side indicates the priority value or identifier, or the predefined priority value or identifier.

For example, pre-define or configure the priority of each MAC CE (for example, the priority of C-RNTI MAC CE or CCCH SDU is a, confirm that the priority of MAC CE is b, the priority of the LCH corresponding to the data is c, and The priority corresponding to BSR MAC CE is d, the priority corresponding to PHR MAC CE is e, the priority corresponding to PUCCH is f, etc.)

For another example, pre-define or configure the priority of each MAC CE (for example, the priority of C-RNTI MAC CE or CCCH SDU is a, confirm that the priority of MAC CE is b, and the priority of LCH corresponding to the URLLC service is c , The priority of the LCH corresponding to the eMBB service is d, the priority corresponding to the BSR MAC CE is d, the priority corresponding to the PUCCH of the SR is e, and the priority corresponding to the HARQ-ACK is m, etc.).

Specifically, the values of a, b, c, d, e, f, and m are all the same or different, and some of them may be the same or different.

When the values of a, b, c, d, e, .., m are different, it can be considered that the priority is higher in the order of a, b, c, d, and e, or it can be considered that the priority is higher in the order of a, b, c, d, and e. The priority of the order of d and e becomes lower.

Taking the lower priority in the order of a, b, c, d, and e as an example, if the highest priority in the explicit information (MAC CE and/or MAC SDU) included in the first uplink transmission is a, and the first The explicit information contained in the second uplink transmission is the SR triggered by the URLLC, and the priority is b, and the UE has priority in the first uplink transmission, as shown in FIG. 6.

In summary, the method provided in this embodiment selects one of the first uplink transmission and the second uplink transmission for transmission according to the first criterion when the first uplink transmission and the second uplink transmission collide. The criterion is not a criterion implemented by the UE itself. Therefore, it can avoid that due to the difference in the criterion implemented by each UE, the UE may select a lower priority uplink transmission for transmission, thereby ensuring that the display with a higher priority is included. The transmission delay of the uplink transmission of the type information meets the delay requirements of the business in the IIoT scenario.

Based on the embodiment shown in FIG. 5, in an optional embodiment, selecting one of the first uplink transmission and the second uplink transmission for priority transmission according to the second criterion includes:

If the priorities of the first explicit information and the second explicit information are the same, which uplink transmission of the first uplink transmission and the second uplink transmission is transmitted first depends on:

1), UE implementation;

2) The priority of PUCCH or PUSCH resources;

In this embodiment, it refers to the priority of the PUSCH corresponding to the first uplink transmission and the PUCCH resource corresponding to the second uplink transmission. Of course, in other possible embodiments, it may also be the priority of PUSCH and PUSCH, the priority of PUCCH and PUCCH, and so on.

3) Preferential transmission of PUCCH;

4) PUSCH is transmitted preferentially.

For another implementation of the first criterion, the following embodiments are provided:

When the first uplink transmission and the second uplink transmission conflict, the UE selects the uplink transmission corresponding to the higher priority category among the first category and the second category for transmission;

The first category is a category corresponding to the first uplink transmission, and the second category is a category corresponding to the second uplink transmission.

Among them, the priority order of the categories includes the following seven categories in descending order of priority:

C-RNTI MAC CE or UL-CCCH data;

Configure authorization confirmation MAC CE;

MAC CE of non-filled BSR;

Single-entry PHR MAC CE or multi-entry PHR MAC CE;

Data of other logical channels except UL-CCCH;

It is recommended to query MAC CE for bit rate;

Fill in the MAC CE of the BSR.

Specifically, the category can be determined according to the LCP priority or rules, and/or other forms of category priority can be adopted.

Figure 7 takes the application of this embodiment in the "CG" vs. "CG" conflict scenario as an example, that is, the first uplink transmission is CG-scheduled uplink transmission, and the second uplink transmission is CG-scheduled uplink transmission as an example, but this embodiment It can also be applied to other conflict scenarios such as "CG" vs. "CG", "DG" vs. "DG". The transmission resources scheduled by the CG or DG may be configured resources on the uplink (Uplink) or configured resources on the side link (SideLink, SL).

FIG. 7 shows a flowchart of a method for resolving transmission conflicts according to another exemplary embodiment of the present application. The method includes:

Step 701: The UE receives a semi-persistent scheduling grant, where the semi-persistent scheduling grant is used to schedule the first uplink transmission on the CG resource;

Step 702: The UE receives DCI, which is used to schedule the second uplink transmission on the DG resource.

Step 703: When the CG resource and the DG resource conflict in the time domain, the uplink transmission corresponding to the higher priority category of the first category and the second category is selected for transmission;

The UE determines the priority based on the category, and different categories have different priorities. In the first uplink transmission and the second uplink transmission, an uplink transmission containing a higher priority category will be transmitted first.

Exemplarily, according to the LCP rule order, each row represents a category, or N rows represent a category, the higher the priority of the category, the higher the priority, and N is an integer greater than 1. For example, in the LCP rules, C-RNTI MAC CE and BSR MAC CE are two categories, and the C-RNTI category has a higher priority.

In an example, the rule order of LCP defines 7 categories. The first category is one of the following 7 categories, and the second category is one of the following 7 categories. The following 7 categories are determined by priority. High to low:

1. C-RNTI MAC CE or UL-CCCH data;

2. Configure the authorization confirmation MAC CE;

3. MAC CE of non-filled BSR;

4. Single-entry PHR MAC CE or multi-entry PHR MAC CE;

5. Data of other logical channels except UL-CCCH;

6. It is recommended to query MAC CE for bit rate;

7. Fill in the MAC CE of the BSR.

Exemplarily, when the category priorities of the first category and the second category are the same, the UE processes according to at least one of the following principles:

-If the highest category of the two uplink transmissions is the same, the transmission is performed according to the uplink transmission corresponding to the category with the second highest priority among the other categories;

Among them, the other categories include categories other than the first category in the first uplink transmission, and categories other than the second category in the second uplink transmission.

In an example, if the priorities of the first category and the second category are the same, the UE performs transmission according to the uplink transmission corresponding to the category with the second highest priority among the other categories. That is, the UE selects the uplink transmission corresponding to the higher priority category among the third category and the fourth category for transmission;

Among them, the third category is the category corresponding to the first uplink transmission, and the priority of the first category is higher than the priority of the third category; the fourth category is the category corresponding to the second uplink transmission, and the priority of the second category is higher Priority in the fourth category.

-If the highest categories in the two uplink transmissions are the same, then determine whether the priorities within the categories in the two uplink transmissions are the same. The priority within the category is determined according to the priority of the included LCH. Or, the priority within the category is determined according to the priority of the MAC CE included in the uplink transmission. Or, the priority within the category is determined according to the priority of the LCH and MAC CE included in the uplink transmission.

In an example, if the priorities of the first category and the second category are the same, the UE selects the corresponding one of the first subcategory of the first category and the second subcategory of the second category according to the priority order of the subcategories Uplink transmission for transmission;

That is, when there are multiple different contents in the above-mentioned LCP categories, more fine-grained subcategories can be divided. For example, for the first category "C-RNTI MAC CE or UL-CCCH data", the sub-category priority of "C-RNTI MAC CE" can be set higher than the sub-category priority of "UL-CCCH data". When the first uplink transmission transmits at least "C-RNTI MAC CE" and the second uplink transmission transmits at least "UL-CCCH data", the first uplink transmission is transmitted first. Or for C-RNTI MAC CE and confirmation MAC CE, suppose they are of one type and belong to different sub-categories. C-RNTI MAC CE is sub-category 1, confirmation MAC CE is sub-category 2, and confirmation MAC CE has a lower priority C-RNTI MAC CE, if the first uplink transmission transmits at least "C-RNTI MAC CE" and the second uplink transmission transmits at least "confirmation MAC CE", the first uplink transmission is transmitted first.

In an example, if the priorities of the first category and the second category are the same, the UE selects the uplink transmission corresponding to the LCH with the higher priority for transmission according to the priority of the LCH in the category;

That is, the UE selects the uplink transmission corresponding to the LCH with higher priority among the first LCH and the second LCH for transmission; wherein, the first LCH is the LCH in the first category, and the second LCH is the LCH in the second category. LCH.

-If the highest categories in the two uplink transmissions are the same, the selection is made according to the second criterion.

-If the highest categories in the two uplink transmissions are the same, then determine whether the priorities within the categories in the two uplink transmissions are the same. If the priority within the category is also the same, the selection is made according to the second criterion.

For example, if the UE determines that the first uplink transmission includes the confirmation MAC CE, BSR MAC CE, and the second uplink transmission includes data, it will confirm that the MAC CE priority is higher than the priority of the data according to the category or LCP rule order, and the UE has priority The first uplink transmission is transmitted, as shown in Figure 8.

For another example, the UE determines that the first uplink transmission includes BSR MAC CE and data 1, and the second uplink transmission includes BSR MAC CE and data 2, according to the category or LCP rule order, the highest priority that can be included in the two uplink transmissions Level information is the same, both are BSR MAC CE, then continue to determine the next priority category, assuming that the data 1 in the first uplink transmission contains the LCH of the high-priority URLLC service, and the data 2 in the second uplink transmission contains For the LCH of the low-priority eMBB service, the UE preferentially transmits the first uplink transmission.

For another example, the UE determines that the first uplink transmission includes BSR MAC CE and data 1, and the second uplink transmission includes BSR MAC CE and data 2, according to the category or LCP rule order, the highest priority that can be included in the two uplink transmissions Level information is the same, both are BSR MAC CE, then continue to determine the priority in this category, assuming that the BSR MAC CE in the first uplink transmission contains the information of the LCH of the high-priority URLLC service, and the BSR in the second uplink transmission The MAC CE contains the LCH information of the low-priority eMBB service, and the first uplink transmission has a higher intra-class priority than the second uplink transmission, and the UE transmits the first uplink transmission first.

-For another example, the UE determines that the first uplink transmission includes BSR MAC CE and data 1, and the second uplink transmission includes BSR MAC CE and data 2, according to the category or LCP rule order, the two uplink transmissions can contain the highest The priority information is the same, and both are BSR MAC CE, and the UE considers the priority of the two uplink transmissions to be the same.

Based on the embodiment shown in FIG. 7, in an optional embodiment, selecting one of the first uplink transmission and the second uplink transmission for priority transmission according to the second criterion includes:

If the category priorities in CG and DG are the same, which of the first uplink transmission and the second uplink transmission is transmitted first depends on:

1), UE implementation;

In other words, the second criterion implemented by the UE itself is built-in by the manufacturer or supplier of the UE when the UE leaves the factory, and the implementation of the UE by different manufacturers or suppliers may be different.

2) The priority of PUCCH or PUSCH resources;

In this embodiment, it refers to the priority of the two PUSCH resources corresponding to the first uplink transmission and the second uplink transmission. Of course, in other possible embodiments, it may also be the priority of PUSCH and PUSCH, the priority of PUCCH and PUCCH, and so on.

3), MAC CE priority.

4) Priority transmission of DG;

5) Priority of LCH.

When the first uplink transmission and the second uplink transmission conflict, the UE selects an uplink transmission with a higher LCP priority for transmission. In other words, according to the LCP priority, the UE determines that the uplink transmission with a higher priority is transmitted first.

That is, when two PUSCHs (Physical Uplink Share Channel, physical uplink control channel) conflict, according to the foregoing LCP rule or sequence, or the enhanced LCP rule or sequence, the PUSCH with higher LCP priority is selected for preferential transmission. Among them, the LCP priority is determined according to the MAC CE and/or LCH in the PUSCH.

On the basis of the foregoing method embodiments, in summary, the method further includes:

When the selection fails according to the first criterion, the UE selects one of the first uplink transmission and the second uplink transmission for transmission according to the second criterion.

In one possible implementation of the second criterion, the second criterion is a criterion implemented by the UE.

In another possible implementation of the second criterion, the UE selects the uplink transmission corresponding to the resource with higher priority among the first resource and the second resource for transmission; the first resource is the PUCCH or PUSCH corresponding to the first uplink transmission Resource, the second resource is a PUCCH or PUSCH resource corresponding to the second uplink transmission.

Among them, PUSCH resources are uplink resources, or side link resources.

In another possible implementation of the second criterion, the UE selects the uplink transmission corresponding to the MAC CE with the higher priority among the second MAC CE and the third MAC CE for transmission;

Among them, the second MAC CE is the MAC CE corresponding to the first uplink transmission, and the third MAC CE is the MAC CE corresponding to the second uplink transmission.
