Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
First, a brief description will be given of relevant contents related to the embodiments of the present application.
IIoT scenario: in a 5G (Fifth Generation) IIoT scene, there is a need to support the transmission of services such as Factory Automation, Transport Automation, intelligent Power Distribution (Electrical Power Distribution) in a 5G system. The method has higher requirements on data transmission delay and reliability.
LCP: (Logical Channel priority), when a UE (User Equipment) acquires an uplink resource for new transmission, data transmission is performed according to the priority of the Logical Channel. The UE performs priority processing of logical channels in the following priority order (in order of priority from high to low), and is divided into 7 categories:
1) data of C-RNTI (Cell Radio Network Temporary Identity ) MAC (Media Access Control) CE (Control Unit) or UL-CCCH (Uplink Common Control Channel);
2) configuring an authorized Grant Confirmation (Configured Grant configuration) MAC CE;
3) MAC CE of non-padding BSR (Buffer Status Report);
4) a Single Entry power headroom report (Single Entry PHR) MAC CE or a Multiple Entry power headroom report (Multiple Entry PHR) MAC CE;
5) data of any logical channel other than UL-CCCH;
6) MAC CE of a bitrate recommendation Query (Recommended Bit Rate Query);
7) the MAC CE of the BSR is padded.
RA: the (Random Access) includes CBRA (Contention-Based Random Access) and CFRA (Contention Free Random Access). Among them, CBRA generally comprises the following 4 steps: (1) the UE sends msg1 to the network equipment; (2) the network device sends msg2 (also called RAR (Random Access Response)) to the UE based on msg 1; (3) the UE sends msg3 to the network device based on msg 2; (4) the network device sends msg4 to the UE based on msg 3. As such, it is necessary to determine whether the UE can successfully access the network in a contention manner. CFRA, among others, generally comprises the following 3 steps: (1) the network equipment sends msg0 to the UE for configuring the special resource for the UE; (2) the UE sends msg1 to the network equipment based on msg0, which is equivalent to initiating a random access request to the network equipment; (3) the network device sends msg2 (i.e., RAR) to the UE based on msg 1. In CFRA, since resources such as preamble (preamble) are dedicated to UE by network equipment, UE initiates RA access to the network using dedicated resources, which avoids the need for UE to perform resource contention determination with other UEs.
In the implementation process, after the UE sends msg1, that is, sends preamble, an RAR monitoring window is opened to monitor a 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 the C-RNTI owned by itself, a C-RNTI MAC CE or CCCH (Common Control Channel) SDU (Service Data Unit) is carried in msg 3.
The reasons for triggering RA are the following:
1) initially accessing a network;
2) RRC (Radio Resource Control) connection reestablishment;
3) downlink data arrives, but uplink data is out of step;
4) uplink data arrives, but uplink is out of step or has no uplink resource;
5) an SR (Scheduling Request) has no corresponding transmission resource;
6) switching;
7) BFR (Beam Failure Recovery);
8) requesting to acquire other system information;
9) transition from RRC-INACTIVE state to connected state.
Wherein, the above-mentioned 3), 4), 5), 6) and 7) are triggering events of RA in a connection state.
The information carried in the UL grant (Uplink Scheduling grant) received by the UE may be: only MAC CE, only MAC SDU, or both MAC CE and MAC SDU. When one grant collides with another grant, or the grant collides with UCI, or the grant collides with PUCCH for carrying UCI, how to determine which uplink transmission (related to MAC CE) needs to be transmitted preferentially is a problem to be solved. Therefore, the embodiment of the present application provides a method for solving a transmission collision, which can solve a problem of how to perform preferential transmission on one uplink transmission when a collision occurs between two uplink transmissions related to a MAC CE, and is specifically implemented as follows.
Next, a brief description will be given of an implementation environment related to the embodiments of the present application.
Referring to FIG. 1, FIG. 1 is a schematic diagram illustrating one implementation environment in accordance with an example embodiment. The implementation environment includes at least one terminal 110 and a network device 120, and fig. 1 illustrates a terminal as an example, and the terminal 110 and the network device 120 can perform data communication through a communication network. The terminal 110 and the network device 120 are both equipped with MAC entities to implement data transmission of the MAC layer through the MAC entities, that is, in this embodiment, the terminal may implement the data transmission method through the MAC entities. As an example, the terminal 110 may be a mobile phone, a tablet computer, an industrial sensor, or other devices capable of data communication, such as a UE in IIoT. In addition, the network device may be a device on the network side, 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 perform direct communication through Sidelink (SL).
Referring to fig. 2, fig. 2 is a flow chart illustrating a method for resolving a transmission collision according to an exemplary embodiment of the present application. The embodiment is exemplified by applying the method to user equipment UE of an industrial internet of things IIoT, and 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 a first criterion.
Optionally, the first criterion is a criterion predefined by the communication protocol, and not 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 may be Dynamic Grant (DG) or semi-static Grant (CG); the second Grant may be Dynamic Grant (DG) or semi-static Grant (CG).
In some embodiments, the first uplink transmission is a transmission for transmitting data and the second uplink transmission is a transmission for transmitting data, when there is a collision between "data" and "data" between the two uplink transmissions.
In some embodiments, the first uplink transmission is a transmission for transmitting at least the MAC CE and the second uplink transmission is a transmission for transmitting data, when there is a collision between the "at least the MAC CE" and the "data" between the two uplink transmissions.
In some embodiments, the first uplink transmission is a transmission for transmitting at least a MAC CE and the second uplink transmission is a transmission for transmitting at least a MAC CE, when there is a collision between the two uplink transmissions between "at least a MAC CE" and "at least a MAC CE". In some embodiments, the first uplink transmission is a transmission for transmitting data and the second uplink transmission is a transmission for transmitting control information, when there is a collision between "data" and "control information" between the two uplink transmissions. The Control Information may be understood as Control channel or Uplink Control Information (UCI).
The first uplink transmission is a transmission for transmitting control information, and the second uplink transmission is a transmission for transmitting control information, and there is a collision between the "control information" and the "control information" between the two uplink transmissions.
The collision of the first uplink transmission and the second uplink transmission refers to: the transmission resource carrying the first uplink transmission and the transmission resource carrying the second uplink transmission are completely or partially overlapped on the time domain.
Optionally, the first criterion includes at least one of the following categories of criteria:
-uplink transmission priority transmission carrying a first MAC CE or a first MAC SDU;
-an uplink transmission priority transmission carrying explicit information of higher priority, which may be at least one of LCH and/or MAC CE transmitted in the uplink transmission; or in the uplink transmission carrying the display information, the uplink transmission corresponding to the display information with higher priority is transmitted preferentially;
-determining uplink transmission priority transmissions having higher class priorities in accordance with the order of class priorities.
-determining uplink transmission priority transmissions having higher priority based on the LCP priority.
In summary, according to the method provided in this embodiment, 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, and the first criterion is not a criterion that the UE implements itself, so that it can be avoided that the UE selects the uplink transmission with a lower priority for transmission by itself due to a difference in criteria that each UE implements by itself, thereby ensuring a transmission delay of the uplink transmission with a higher priority, and meeting a delay requirement of a service in an IIoT scenario.
For one 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 containing the first MAC CE or the specific MAC SDU from the first uplink transmission and the second uplink transmission for transmission.
Wherein the first MAC CE includes at least one of the following MAC CEs:
MAC CE with priority not less than PUSCH priority;
a MAC CE having a specific priority;
MAC CE with specific use;
MAC CE with specific trigger cause;
MAC CEs with priority above the threshold.
Wherein, the specific MAC SDU is a MAC SDU corresponding to the specific logical channel. The specific logical channel refers to a logical channel configured or designated by a network, or a logical channel predefined by a communication protocol.
"specific" in this context may be understood as a configuration or designation of the network, or, alternatively, as a predefined communication protocol. The term "specific" is also to be understood as: the meaning of specific LCH priority, specific LCH identity, specific traffic transmission, etc. is not limited in this application.
The "threshold" may be configured by RRC (Radio Resource Control), predefined, or indicated by DCI (Downlink Control Information).
In one example, the MAC CEs having the specific priority include at least one of the following MAC CEs: a MAC CE with a particular priority identification; 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, and the like, which are not limited in the present application.
In one example, the MAC CE with a particular use includes at least one of the following MAC CEs: acknowledgement (Confirmation) MAC CE; CCCH SDU; C-RNTI; BSR MAC CE; PHR MAC CE.
In one example, the MAC CE with the specific trigger cause includes at least one of the following MAC CEs:

the MAC CE is used for confirming the activation or deactivation of the CG corresponding to the URLLC service;
the MAC CE is used for confirming activation or deactivation of the CG corresponding to the URLLC logical channel;
the system is used for reporting the MAC CE triggered by the BSR;

Fig. 3 exemplifies that the present embodiment is applied to a "CG" vs "DG" collision scenario, that is, the first uplink transmission is uplink transmission scheduled by the CG, and the second uplink transmission is uplink transmission scheduled by the DG, but the present embodiment may also be applied to other collision scenarios such as "CG" vs "CG", "DG" vs "DG", "data" vs "UCI", "UCI" vs "UCI", and the like. The transmission resource scheduled by the CG may be a configuration resource on an Uplink (Uplink) or a configuration resource on a SideLink (SL).
Fig. 3 is a flowchart illustrating a method for resolving a transmission collision according to an exemplary embodiment of the present application. The method comprises the following steps:
step 301, a UE receives a semi-persistent scheduling grant, where the semi-persistent scheduling grant is used for scheduling a first uplink transmission on a CG resource;
this semi-persistent scheduling grant is also referred to as a CG configuration. The semi-persistent scheduling grant is configured for a first uplink transmission on a periodically occurring transmission resource.
Step 302, the UE receives DCI, where the DCI is used to schedule a second uplink transmission on a DG resource;
the DCI is used for dynamic scheduling. The dynamic scheduling is configured to perform a second uplink transmission on the transmission resource dynamically configured this time.
Step 303, when the CG resource and the DG resource collide in the time domain, selecting the uplink transmission including the first MAC CE or the first MAC SDU in the first uplink transmission and the second uplink transmission for transmission.
Referring to fig. 4 in combination, 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.
And when the first uplink transmission and the second uplink transmission both comprise the first MAC CE (or the first MAC SDU), selecting one uplink transmission from the first uplink transmission and the second uplink transmission according to a second criterion for preferential transmission.
For example, if the UE determines that the first uplink transmission includes C-RNTI MAC CE and the second uplink transmission does not include the first MAC CE, the UE determines to preferentially transmit the first uplink transmission.
For another example, if the UE determines that the first uplink transmission contains data (or MAC SDU) of the logical channel of the URLLC, and the second uplink transmission does not contain the first MAC SDU, the UE determines to preferentially transmit the first uplink transmission.
In summary, in the method provided in this embodiment, 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, and the first criterion is not a criterion that the UE implements itself, so that it can be avoided that the UE selects an uplink transmission with a lower priority for transmission by itself due to a difference in criteria that each UE implements by itself, thereby ensuring a transmission delay of the uplink transmission including the first MAC CE or the first MAC SDU, and meeting a delay requirement of a service in an IIoT scenario.
Based on the embodiment shown in fig. 3, in an alternative embodiment, selecting one of the first uplink transmission and the second uplink transmission for preferential transmission according to a second criterion includes:
if both CG and DG contain data of the first MAC CE or the first logical channel (or MAC SDU), then the priority of the conflicting resources or information determined by the UE is the same, or it is determined that no resource satisfies the above condition (i.e. both satisfy this condition), then which of the first uplink transmission and the second uplink transmission is transmitted preferentially depends on:
1) UE implementation;
that is, when the UE leaves the factory, the manufacturer or the provider of the UE embeds the second criterion that the UE implements itself, and the UE implementations of different manufacturers or providers may be different.
When the UE performs self-implementation, it may select one of the two uplink transmissions, or select an uplink transmission with a starting time earlier, or select an uplink transmission with a starting time later, or select an uplink transmission with an ending time earlier or later, or select a PUSCH, or a PUCCH, or a PUSCH carrying UCI, and the like, which is not limited in the embodiment of the present application.
2) Priority of PUCCH or PUSCH resources;
in this embodiment, the priority of two PUSCH resources corresponding to the first uplink transmission and the second uplink transmission is referred to.
3) Priority of the MAC CE;
a highest-priority MAC CE among a plurality of MAC CEs included in two uplink transmissions (or transmission resources), or a highest-priority MAC CE among at least one MAC CE among first MAC CEs included in two resources.
4) Preferentially transmitting DGs;
5) the second highest priority LCH.
For another possible implementation of the first criterion, the following embodiments are provided:
when the first uplink transmission conflicts with the second uplink transmission, the UE selects the uplink transmission corresponding to the explicit information with higher priority from the first explicit information and the second explicit information for transmission;
the first explicit information is an LCH and/or MAC CE corresponding to the first uplink transmission, and the second explicit information is an LCH and/or MAC CE corresponding to the second uplink transmission.
Wherein the first explicit information is preconfigured or predefined or network side configured or network side indicated; the second explicit information is pre-configured or pre-defined or network side configured or network side indicated.
In one example, the first uplink transmission corresponds to LCH1, the second uplink transmission corresponds to LCH2, and the first uplink transmission is preferentially transmitted when LCH1 has a higher priority than LCH 2; and when the priority of the LCH1 is lower than that of the LCH2, the second uplink transmission is transmitted preferentially.
In another example, the first uplink transmission corresponds to LCH1, the second uplink transmission corresponds to MAC CE2, and the first uplink transmission is preferentially transmitted when LCH1 has a higher priority than MAC CE 2; and when the priority of the LCH1 is lower than that of the MAC CE2, the second uplink transmission is transmitted preferentially.
In one example, the first uplink transmission corresponds to MAC CE1, the second uplink transmission corresponds to MAC CE2, and the first uplink transmission is preferentially transmitted when the priority of MAC CE1 is higher than the priority of MAC CE 2; when the priority of the MAC CE1 is lower than that of the MAC CE2, the second uplink transmission is transmitted preferentially.
Fig. 5 illustrates the application of the present embodiment to the "data" vs "PDCCH" collision scenario as an example, but the present embodiment may also be applied to other collision scenarios such as "data" vs "data". The transmission resource for transmitting data may be a configuration resource on an Uplink (Uplink) or a configuration resource on a SideLink (SL).
Fig. 5 is a flowchart illustrating a method for resolving a transmission collision according to another exemplary embodiment of the present application. The method comprises the following steps:
step 501, a UE receives a semi-persistent scheduling grant, where the semi-persistent scheduling grant is used for scheduling a first uplink transmission on a CG resource;
this semi-persistent scheduling grant is also referred to as a CG configuration. The semi-persistent scheduling grant is configured for a first uplink transmission on a periodically occurring transmission resource. For example, the first uplink transmission is performed on the PUSCH resource starting at time t 1.
Step 502, the UE receives DCI, where the DCI is used to schedule a second uplink transmission on a DG resource;
the DCI is used for dynamic scheduling. The dynamic scheduling is configured to perform a 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 t 1. Therefore, the PUSCH resource and the PUCCH resource collide.
Step 503, when the CG resource and the DG resource collide in the time domain, the UE selects the uplink transmission corresponding to the explicit information with higher priority from the first explicit information and the second explicit information for transmission;
the first explicit information is an LCH and/or MAC CE corresponding to the first uplink transmission, and the second explicit information is an LCH and/or MAC CE corresponding to the second uplink transmission.
The first criterion includes: and carrying out priority transmission on the uplink transmission containing the explicit information with higher priority. Specifically, at least one LCH and at least one MAC CE are configured with priority values or representations by the network side, or the network side indicates the priority values or identifiers, or predefines the priority values or identifiers.
For example, the priority of each MAC CE is predefined or configured (e.g., C-RNTI MAC CE or CCCH SDU has a priority of a, acknowledgement MAC CE has a priority of b, LCH corresponding to data has a priority of C, BSR MAC CE has a priority of d, PHR MAC CE has a priority of e, PUCCH has a priority of f, etc.)
For example, the priority of each MAC CE is predefined or configured (e.g., C-RNTI MAC CE or CCCH SDU has a priority, acknowledgement MAC CE has b priority, LCH corresponding to URLLC traffic has C priority, LCH corresponding to eMBB traffic has d priority, BSR MAC CE has d priority, PUCCH corresponding to SR has e priority, HARQ-ACK has m priority, etc.).
Specifically, the values of a, b, c, d, e, f and m are all the same or different, and may also be partially the same or different.
When the values of a, b, c, d, e, and m are different, the priority may be considered to be higher in the order of a, b, c, d, and e, or may be considered to be lower in the order of a, b, c, d, and e.
Taking the example that the priority becomes lower according to the order of a, b, c, d, e, if the highest priority in the explicit information (MAC CE and/or MAC SDU) contained in the first uplink transmission is a, the explicit information contained in the second uplink transmission is SR triggered by URLLC, and the priority is b, the UE prioritizes the first uplink transmission, as shown in fig. 6.
In summary, according to the method provided in this embodiment, 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, and the first criterion is not a criterion that the UE implements itself, so that it can be avoided that the UE selects an uplink transmission with a lower priority for transmission by itself due to a difference in criteria that each UE implements by itself, thereby ensuring a transmission delay of the uplink transmission including explicit information with a higher priority, and meeting a delay requirement of a service in an IIoT scenario.
Based on the embodiment shown in fig. 5, in an alternative embodiment, selecting one of the first uplink transmission and the second uplink transmission for preferential transmission according to a second criterion includes:
if the priorities of the first explicit information and the second explicit information are the same, which of the first uplink transmission and the second uplink transmission is preferentially transmitted depends on:
1) UE implementation;
that is, when the UE leaves the factory, the manufacturer or the provider of the UE embeds the second criterion that the UE implements itself, and the UE implementations of different manufacturers or providers may be different.
When the UE performs self-implementation, it may select one of the two uplink transmissions, or select an uplink transmission with a starting time earlier, or select an uplink transmission with a starting time later, or select an uplink transmission with an ending time earlier or later, or select a PUSCH, or a PUCCH, or a PUSCH carrying UCI, and the like, which is not limited in the embodiment of the present application.
2) Priority of PUCCH or PUSCH resources;
in this embodiment, the priority of the PUSCH corresponding to the first uplink transmission and the priority of the PUCCH resource corresponding to the second uplink transmission are referred to. Of course, in other possible embodiments, there may also be a priority of PUSCH and PUSCH, a priority of PUCCH and PUCCH, and so on.
3) Transmitting PUCCH preferentially;
4) and transmitting the PUSCH preferentially.
For another implementation of the first criterion, the following embodiments are provided:
when the first uplink transmission conflicts with the second uplink transmission, the UE selects the uplink transmission corresponding to the category with higher priority from 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.
The priority order of the categories comprises the following seven categories in the priority order from high to low:
C-RNTI MAC CE or UL-CCCH data;
configuring an authorization acknowledgement MAC CE;
MAC CE of non-padding BSR;
a single-entry PHR MAC CE or a multi-entry PHR MAC CE;
data of other logical channels than UL-CCCH;
bit rate recommendation querying MAC CEs;
the MAC CE of the BSR is padded.
In particular, the categories may be determined according to LCP priorities or rules, and/or other forms of prioritization of the categories may be employed.
Fig. 7 illustrates an example in which the present embodiment is applied to a "CG" vs "CG" collision scenario, that is, the first uplink transmission is uplink transmission scheduled by a CG, and the second uplink transmission is uplink transmission scheduled by a CG, but the present embodiment may also be applied to other collision scenarios such as "CG" vs "CG", "DG" vs "DG", and the like. The transmission resource scheduled by the CG or the DG may be a configuration resource on an Uplink (Uplink) or a configuration resource on a SideLink (SL).
Fig. 7 is a flowchart illustrating a method for resolving a transmission collision according to another exemplary embodiment of the present application. The method comprises the following steps:
step 701, the UE receives a semi-persistent scheduling grant, where the semi-persistent scheduling grant is used for scheduling a first uplink transmission on a CG resource;
this semi-persistent scheduling grant is also referred to as a CG configuration. The semi-persistent scheduling grant is configured for a first uplink transmission on a periodically occurring transmission resource. For example, the first uplink transmission is performed on the PUSCH resource starting at time t 1.
Step 702, the UE receives DCI, where the DCI is used to schedule a second uplink transmission on a DG resource;
the DCI is used for dynamic scheduling. The dynamic scheduling is configured to perform a 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 t 1. Therefore, the PUSCH resource and the PUCCH resource collide.
Step 703, when the CG resource and the DG resource collide in the time domain, selecting the uplink transmission corresponding to the category with higher priority from 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.
The UE determines the priority based on the category, with different categories having different priorities. In the first uplink transmission and the second uplink transmission, one uplink transmission including a higher priority class is to be preferentially transmitted.
Illustratively, each row may represent a category, or N rows may represent a category, with the earlier categories having higher priority, N being an integer greater than 1, in the order of the rules of the LCP. For example, in the LCP rule, C-RNTI MAC CE and BSR MAC CE are two categories, and the category of C-RNTI has a high priority.
In one example, the rule order of LCP defines 7 categories, the first category is one of the following 7 categories, the second category is one of the following 7 categories, the following 7 categories are from high to low according to priority:
1. C-RNTI MAC CE or UL-CCCH data;
2. configuring an authorization acknowledgement MAC CE;
3. MAC CE of non-padding BSR;
4. a single-entry PHR MAC CE or a multi-entry PHR MAC CE;
5. data of other logical channels than UL-CCCH;
6. bit rate recommendation querying MAC CEs;
7. the MAC CE of the BSR is padded.
Illustratively, when the class priorities of the first class and the second class are the same, the UE processes according to at least one of the following principles:
-if the highest of the two uplink transmissions is the same, transmitting according to the uplink transmission corresponding to the category with the second highest priority among the other categories;
the other categories include a category except the first category in the first uplink transmission and a category except the second category in the second uplink transmission.
In one example, if the priorities of the first category and the second category are the same, the UE transmits according to uplink transmission corresponding to a category with the second highest priority among other categories. That is, the UE selects uplink transmission corresponding to a category with higher priority from the third category and the fourth category for transmission;
the third category is a category corresponding to the first uplink transmission, and the priority of the first category is higher than that of the third category; the fourth category is a category corresponding to the second uplink transmission, and the priority of the second category is higher than the priority of the fourth category.
-if the highest class in the two uplink transmissions is the same, determining if the intra-class priorities in the two uplink transmissions are the same. The intra-category priority is determined according to the priority of the included LCHs. Or, the priority in the category is determined according to the priority of the MAC CE contained in the uplink transmission. Or, the priority in the category is determined according to the priority of LCH and MAC CE contained in the uplink transmission.
In one example, if the priorities of the first category and the second category are the same, the UE selects uplink transmissions corresponding to a first sub-category of the first category and a second sub-category of the second category for transmission according to the priority order of the sub-categories;
that is, for multiple different items of content in the above LCP category, finer grained subcategories may be partitioned. For example, for a first category of data of "C-RNTI MAC CE or UL-CCCH", a subcategory priority of "C-RNTI MAC CE" may be set higher than a subcategory priority of "data of UL-CCCH". When the first uplink transmission transmits at least 'C-RNTI MAC CE' and the second uplink transmission transmits at least 'data of UL-CCCH', the first uplink transmission is preferentially transmitted. Or for C-RNTI MAC CE and the retransmission MAC CE, assuming that they are of one type and belong to different subcategories, C-RNTI MAC CE is subcategory one, the retransmission MAC CE is subcategory two, the priority of the retransmission MAC CE is lower than that of C-RNTI MAC CE, and if the first uplink transmission transmits at least "C-RNTI MAC CE" and the second uplink transmission transmits at least "retransmission MAC CE", the first uplink transmission is preferentially transmitted.
In one example, if the priorities of the first category and the second category are the same, the UE selects uplink transmission corresponding to an LCH with a higher priority for transmission according to the priorities of the LCHs in the categories;
that is, the UE selects uplink transmission corresponding to the LCH with higher priority from the first LCH and the second LCH for transmission; wherein the first LCH is an LCH within the first category and the second LCH is an LCH within the second category.
-selecting according to a second criterion if the highest class in the two uplink transmissions is the same.
-if the highest class in the two uplink transmissions is the same, determining if the intra-class priorities in the two uplink transmissions are the same. If the priorities within the categories are also the same, the selection is made according to a second criterion.
For example, if the UE determines that the first uplink transmission includes an acknowledgement MAC CE, a BSR MAC CE, and the second uplink transmission includes data, the UE preferentially transmits the first uplink transmission if the priority of the acknowledgement MAC CE is higher than the priority of the data according to the category or LCP rule sequence, as shown in fig. 8.
For another example, if the UE determines that the first uplink transmission includes BSR MAC CE and data 1, and the BSR MAC CE and data 2 included in the second uplink transmission are both BSR MAC CE and the highest priority information included in the two uplink transmissions is the same according to the category or LCP rule order, the UE continues to determine the category of the next priority, and assumes that the data 1 in the first uplink transmission includes LCH of the URLLC service with high priority, and the data 2 in the second uplink transmission includes LCH of the eMBB service with low priority, the UE preferentially transmits the first uplink transmission.
For another example, if the UE determines that the first uplink transmission includes BSR MAC CE and data 1, and the BSR MAC CE and data 2 included in the second uplink transmission are, according to the category or LCP rule order, the highest priority information that may be included in the two uplink transmissions is the same and is BSR MAC CE, the UE continues to determine the priority in the category, and if the BSR MAC CE in the first uplink transmission includes information of LCH of the URLLC service with high priority, and the BSR MAC CE in the second uplink transmission includes information of LCH of the eMBB service with low priority, the priority in the category of the first uplink transmission is higher than the priority in the category of the second uplink transmission, and the UE preferentially transmits the first uplink transmission.
For another example, if 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, then according to the category or LCP rule order, the highest priority information that the two uplink transmissions may include is the same, and both uplink transmissions are BSR MAC CEs, and then the UE considers the priorities of the two uplink transmissions to be the same.
In summary, in the method provided in this embodiment, 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, and the first criterion is not a criterion that the UE implements itself, so that it can be avoided that the UE selects an uplink transmission with a lower priority for transmission by itself due to a difference in criteria that each UE implements by itself, thereby ensuring a transmission delay of the uplink transmission including the first MAC CE or the first MAC SDU, and meeting a delay requirement of a service in an IIoT scenario.
Based on the embodiment shown in fig. 7, in an alternative embodiment, selecting one of the first uplink transmission and the second uplink transmission for preferential transmission according to a second criterion includes:
if the class priorities in CG and DG are the same, which of the first uplink transmission and the second uplink transmission is preferentially transmitted depends on:
1) UE implementation;
that is, when the UE leaves the factory, the manufacturer or the provider of the UE embeds the second criterion that the UE implements itself, and the UE implementations of different manufacturers or providers may be different.
When the UE performs self-implementation, it may select one of the two uplink transmissions, or select an uplink transmission with a starting time earlier, or select an uplink transmission with a starting time later, or select an uplink transmission with an ending time earlier or later, or select a PUSCH, or a PUCCH, or a PUSCH carrying UCI, and the like, which is not limited in the embodiment of the present application.
2) Priority of PUCCH or PUSCH resources;
in this embodiment, the priority of two PUSCH resources corresponding to the first uplink transmission and the second uplink transmission is referred to. Of course, in other possible embodiments, there may also be priorities of PUSCH and PUSCH, priorities of PUCCH and PUCCH, and the like.
3) Priority of MAC CE.
A highest-priority MAC CE among a plurality of MAC CEs included in two uplink transmissions (or transmission resources), or a highest-priority MAC CE among at least one MAC CE among first MAC CEs included in two resources.
4) Preferentially transmitting DGs;
5) priority of LCH.
For another implementation of the first criterion, the following embodiments are provided:
when the first uplink transmission and the second uplink transmission collide, the UE selects an uplink transmission having a higher LCP priority for transmission. In other words, the UE determines uplink transmission priority transmission having higher priority according to the LCP priority.
That is, when there are two PUSCH (Physical Uplink Share Channel) collisions, the PUSCH with the higher LCP priority is selected for preferential transmission according to the above LCP rule or order, or the enhanced LCP rule or order. Wherein the LCP priority is determined according to the MAC CE and/or the LCH in the PUSCH.
On the basis of the above embodiments of the method, to sum up, 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 according to a second criterion for transmission.
In one possible implementation of the second criterion, the second criterion is a UE-implemented criterion.
In another possible implementation of the second criterion, the UE selects uplink transmission corresponding to a resource with higher priority from the first resource and the second resource for transmission; the first resource is a PUCCH or PUSCH resource corresponding to the first uplink transmission, and the second resource is a PUCCH or PUSCH resource corresponding to the second uplink transmission.
Wherein the PUSCH resource is an uplink resource, or, a sidelink resource.
In another possible implementation of the second criterion, the UE selects uplink transmission corresponding to the MAC CE with higher priority from the second MAC CE and the third MAC CE for transmission;
and 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.
