In this specification, the specific meaning of "the preconfigured resource on one frequency band resource generates collision" means that a plurality of sets of preconfigured resource on one frequency band resource overlap in time domain.

The data transmission method provided by the embodiment of the invention obtains at least two sets of pre-configured resources on a frequency band resource configured for the terminal by communication equipment; when the pre-configured resources on one frequency band resource generate conflict, if the terminal can not use the pre-configured resources generating conflict to transmit data at the time of conflict, determining a set of pre-configured resources from the pre-configured resources generating conflict to transmit uplink data; the problem of how to select which pre-configured resource to use when the terminal only supports transmission of one TB on one BWP at the same time and when a plurality of sets of pre-configured resources exist at the same time and the time domain has collision can be solved; therefore, the correct transmission of the data is ensured, and the problem that the data transmission cannot be correctly carried out after a plurality of sets of pre-configured resources on one BWP conflict in the prior art is well solved.

Wherein, determining a set of pre-configured resources from the pre-configured resources generating the collision for data transmission comprises: in the first case, a set of pre-configured resources are determined from the pre-configured resources with conflicts to carry out uplink data transmission; or in case two, according to the appointed information between the communication equipment and the terminal, determining a set of pre-configured resources from the pre-configured resources generating conflict to perform uplink data transmission; or in the third case, according to the indication information sent by the communication device, a set of pre-configured resources is determined from the pre-configured resources in which the collision occurs, and the uplink data is sent.

Specifically, determining a set of pre-configured resources from the pre-configured resources generating the collision to perform uplink data transmission includes at least one of the following: selecting a pre-configured resource with the minimum period from the pre-configured resources generating the conflict to carry out uplink data transmission; selecting pre-configured resources capable of containing most data from the pre-configured resources generating the conflict to carry out uplink data transmission; selecting a pre-configured resource from the pre-configured resources generating the conflict to carry out uplink data transmission according to the service quality requirement of the current service of the terminal; if conflict is generated between the pre-configured resource configured with the authorization type1 and the pre-configured resource configured with the authorization type2, selecting the pre-configured resource configured with the authorization type2 or selecting the pre-configured resource configured with the authorization type1 to transmit uplink data;

For case three, the indication information is identification information of a pre-configured resource required to be used when a collision occurs to the pre-configured resource configured by the terminal on one frequency band resource (embodiment form one); or the indication information is a priority usage order of pre-configured resources configured for the terminal and conflicting when the pre-configured resources on one frequency band resource conflict (embodiment two).

When the indication information is transmitted, radio resource control RRC signaling (mode one), medium access control element MAC CE (mode two), or physical layer control signaling (mode three) is used.

For the first mode, the RRC signaling is RRC signaling carrying preconfigured resources, or the RRC signaling is RRC signaling carrying logical channel configuration information.

When the RRC signaling is the RRC signaling carrying the logical channel configuration information and the pre-configured resources on one frequency band resource conflict with respect to different logical channels, the pre-configured resources required to be used by different logical channels are the same or different; or when the RRC signaling is the RRC signaling carrying the logical channel configuration information, and when the preconfigured resources on one band resource conflict with respect to different logical channels, the priority usage orders of the preconfigured resources that conflict with each other corresponding to different logical channels are the same or different.

For the second mode, if the MAC CE is used during the transmission of the indication information, the MAC CE is identified by using a dedicated logical channel identifier LCID. Wherein "dedicated LCID" refers to an unused LCID that has been defined; or a newly defined LCID, which is not limited herein.

For the first embodiment, if the indication information is identification information of a pre-configured resource that needs to be used when a collision occurs to a pre-configured resource configured by the terminal on one frequency band resource, then: the MAC subheader at least comprises an LCID indication domain; the MAC CE only carries identification information of one pre-configured resource, and the rest bits are reserved domains; or the MAC subheader at least comprises an LCID indication domain; and the MAC CE at least comprises a logical channel identifier and identifier information of the pre-configured resource which is used when the pre-configured resource on one frequency band resource corresponding to the logical channel generates conflict, and the rest bits are reserved fields.

The MAC subheader also comprises a length indication field, and the rest bits are reserved fields.

For embodiment two, if the indication information is a priority usage order of pre-configured resources configured for the terminal and conflicting when the pre-configured resources on one frequency band resource conflict, then: the MAC subheader at least comprises an LCID indication domain; and the MAC CE carries the priority indication information corresponding to the identifiers of the pre-configured resources which generate the conflict in sequence according to the sequence of the identifiers of the pre-configured resources, and the rest bits are reserved domains.

Wherein the set of pre-configured resources that generate the collision may be a maximum set of pre-configured resources that the communication device is allowed to configure for the terminal.

Further, the MAC subheader further includes a length indication field, and the remaining bits are reserved fields. The pre-configured resource that generates the collision may be a pre-configured resource actually configured by the communication device for the terminal.

For embodiment two, if the indication information is a priority usage order of pre-configured resources configured for the terminal and conflicting when the pre-configured resources on one frequency band resource conflict, then: the MAC subheader at least comprises an LCID indication domain and a length indication domain, and the rest bits are reserved domains; the MAC CE comprises a bit mapping bitmap indication domain and priority indication information of the preconfigured resources with bitmap indication of 1, and the rest bits are reserved domains; wherein, the bitmap indication field comprises at least two bits, each bit is used for indicating whether the current MAC CE comprises the priority indication information of the pre-configured resource associated with the bit; or

For the third mode, if the physical layer control signaling is used when the indication information is transmitted, the indication information is carried in the Physical Downlink Control Channel (PDCCH) signaling activated by the preconfigured resource; or adopting a separate physical layer control signaling to carry the indication information.

Further, before determining a set of pre-configured resources from the pre-configured resources generating the collision for uplink data transmission according to the indication information sent by the communication device, the method further includes: reporting the capability indication information of the terminal to the communication equipment; receiving indication information issued by the communication equipment according to the capability indication information; the capability indication information is used for indicating whether the terminal can simultaneously transmit data on at least two sets of pre-configured resources on the same frequency band resource at the same time.

In this embodiment of the present invention, the indication manner of the frequency band resource includes: the frequency point and the bandwidth where the frequency band resource is located; or the band combination identification information of the band resource.

Specifically, the communication device may be a network device or other terminal that communicates with the terminal.

The uplink data transmission method provided in the embodiment of the present invention is further described below with reference to a terminal side and a communication device side, where the bandwidth resource is BWP as an example, and the communication device is a network device as an example.

In view of the above technical problems, an embodiment of the present invention provides an uplink data transmission method, including a method for resolving a conflict between at least two sets of preconfigured resources; mainly relates to: if the terminal has at least two sets of pre-configured resources at the same time and the terminal capability does not support simultaneous transmission on the at least two sets of pre-configured resources, the terminal selects one set of pre-configured resources from the at least two sets of pre-configured resources generating the conflict at the conflict time according to a pre-specified principle to send uplink data.

Specifically, the specific principle may be any of the following:

and Option 1, the terminal determines the pre-configured resources specifically used at the conflict moment by itself based on the terminal implementation.

The specific principle can be one of the following or a combination of partial principles:

(1) the terminal always selects the pre-configured resource with the minimum period;

(2) the terminal always selects a pre-configured resource capable of accommodating the most data;

(3) the terminal selects a pre-configured resource according to the QoS requirement of the current service;

(4) if there is a conflict between the Type1 (configuration grant Type1 described above) and Type2 (configuration grant Type2 described above) resources, the terminal always selects Type2 or always selects Type 1.

And Option 2, the terminal determines the pre-configured resources specifically used at the conflict moment according to the appointed information of the network equipment.

For example, the selection principle of the terminal if the terminal has at least two sets of pre-configured resources conflicting is agreed in the protocol. The specific principles in Option 1 may be included.

And Option 3, the terminal determines the pre-configured resources specifically used at the conflict moment according to the indication information of the network equipment (which can be a base station, a centralized unit CU or a distribution unit DU).

The content of the indication information can be in two forms:

alt (attribute) 1, pre-configured resource identification information to be used specifically when the indication information is a conflict, such as a pre-configured resource number;

and Alt 2, indicating the priority sequence among the pre-configured resources with the information generating conflict for the conflict moment.

The signaling bearer format of the indication information (signaling used in transmission of the indication information) may be as follows:

option 3.1 RRC Signaling

The indication information may be specifically carried in:

(1) carrying RRC signaling of pre-configured resources;

(2) and carrying the RRC signaling of the logical channel configuration information.

If the logical channel is the same as the logical channel, the pre-configured resources selected by different logical channels in case of conflict or the pre-configured resources corresponding to different logical channels in case of conflict may have the same or different priority usage order.

And Option 3.2: media access control unit (MAC CE)

In order to identify the MAC CE, a dedicated logical channel identification LCID needs to be introduced (i.e., the new LCID used identifies the MAC CE). "dedicated LCID" refers to an unused LCID that has been defined; or a newly defined LCID.

(1) When the indication information is the pre-configured resource identification information to be used specifically when the indication information is in conflict, the MAC CE is specifically designed with several possibilities:

MAC CE design method 1:

MAC sub-header: at least containing LCID indication field, redundant (residual) bit position can be set as reserved field R; and is

MAC CE: only one pre-configured resource identification information is carried, and redundant bit positions can be set as a reserved field R.

MAC CE design method 2:

MAC sub-header: at least comprises an LCID indication field, optionally an L field (length indication field), and redundant bit positions can be set as a reserved field R; and is

MAC CE: at least comprises logical channel identification and pre-configuration resource identification information needed to be used when the logical channel corresponds to the conflict. The redundant bit positions may be set to the reserved field R.

(2) When the indication information is a priority order between the pre-configured resources which conflict at the moment of conflict, the MAC CE is specifically designed with several possibilities:

MAC CE design method 1:

MAC sub-header: at least containing LCID indication domain, setting redundant bit position as reserved domain R, optionally, also containing L domain, then setting redundant bit position as reserved domain R;

MAC CE: according to the order of the preconfigured resource identifiers (such as the order of the preconfigured resource indexes), priority indication information (the indication information) corresponding to the preconfigured resource identifiers which generate the collision is sequentially carried, and redundant bit positions can be set as a reserved field R. The pre-configured resource causing the collision may be a pre-configured resource actually configured by the network device for the terminal (at this time, the MAC subheader needs to include the L field), or a maximum number of pre-configured resource sets allowed to be configured for the terminal by the network device (at this time, the MAC subheader does not need to carry the L field).

MAC CE design method 2:

MAC sub-header: at least comprises an LCID indication domain and a length indication domain L domain, and the position of redundant bits can be set as a reserved domain R;

MAC CE: the method comprises a bitmap indication domain of bit mapping and priority indication information of the pre-configured resource with bitmap indication of 1, and redundant bit positions can be set as a reserved domain R; the bitmap indication field is used to indicate which sets of priority indication information of the preconfigured resources are included in the current MAC CE (specifically, the bitmap indication field includes at least two bits, and each bit is used to indicate whether the current MAC CE includes the priority indication information of the preconfigured resources associated with the bit).

MAC CE design method 3:

MAC sub-header: MAC sub-header: at least comprises an LCID indication domain and a length indication domain L domain, and the position of redundant bits can be set as a reserved domain R;

MAC CE: for example, for logical channel 1, the corresponding pre-configured resource priority is that pre-configured resource 1 has the highest priority, and pre-configured resource 2 has the next highest priority, and for logical channel 2, the corresponding pre-configured resource priority is that pre-configured resource 2 has the highest priority, and pre-configured resource 1 has the next highest priority. Therefore, in the MAC CE, a logical channel identifier, a bitmap indication field corresponding to the logical channel, and priority indication information of the preconfigured resource whose bitmap indication is 1 need to be configured for each logical channel, and redundant bit positions may be set as a reserved field R; the bitmap indication field corresponding to the logical channel is used to indicate which sets of priority indication information of the preconfigured resources are included in the current MAC CE for the logical channel (specifically, the bitmap indication field corresponding to the logical channel includes at least two bits, and each bit is used to indicate whether the current MAC CE includes the priority indication information of the preconfigured resources associated with the bit for the logical channel).

And Option 3.3: physical layer control signaling

The indication information is carried in a Physical Downlink Control Channel (PDCCH) signaling activated by a pre-configured resource; or adopting a separate physical layer control signaling to carry the indication information. Specific examples thereof are:

if there are only preconfigured resources of Type2, the indication information may be carried in PDCCH signaling activated by the preconfigured resources (each set of preconfigured resources corresponds to one PDCCH signaling, and in the embodiment of the present invention, one set of preconfigured resources is selected for use). However, if the preconfigured resources include both Type1 preconfigured resources and Type2 preconfigured resources, then it is preferable to introduce a separate physical layer control signaling to carry the indication information.

For Option 3, the terminal needs to report capability indication information to the network device, indicating whether the terminal transmits simultaneously on the same BWP at the same time (the network device determines whether to configure the selection of the pre-configuration information). The BWP may be embodied in the form of BWP or in the form of bandcombination (that is, the bandcombination includes only one band, that is, the band where the BWP is located). The BWP can directly indicate the frequency point and the bandwidth of the BWP during signaling design; the indication may be a band combination identifier, which is only the band identifier where the BWP is located, according to the existing bandcombination manner. It is understood that the indication manner of BWP includes: frequency point and bandwidth of BWP; or band combination identification information of the band where the BWP is located.

The above-described scheme provided by the embodiments of the present invention is exemplified below.

Example 1: for the above Option 1;

network equipment side:

and configuring at least two sets of pre-configured resources for the terminal based on the current service characteristics of the terminal.

A terminal side:

if the terminal has at least two sets of pre-configured resources at the same time and the terminal capability does not support simultaneous transmission on the at least two sets of pre-configured resources, the terminal selects one set of pre-configured resources from the at least two sets of pre-configured resources generating the conflict at the conflict time according to a pre-specified principle to send uplink data.

In this example, the terminal determines the pre-configured resource specifically used at the collision time by itself based on the terminal implementation, and the specific principle may be one of the following principles or a combination of some of the principles:

the terminal always selects the pre-configured resource with the minimum period;

the terminal always selects a pre-configured resource capable of accommodating the most data; for example, the maximum data to accommodate may be determined according to TB size (transport block size) supported by the pre-configured resource.

The terminal selects a pre-configured resource according to the QoS requirement of the current service; for example, the terminal selects according to the QoS requirements of the current logical channels having data to transmit.

If there is a conflict between Type1 and Type2 resources, the terminal always selects Type2 or always selects Type 1.

In this example, the network device does not need to know the pre-configured resource determined by the terminal, and performs blind detection on the resources that may be used by all terminals.

Example 2: for the Option 2;

network equipment side:

If the terminal has at least two sets of pre-configured resources at the same time and the terminal capability does not support simultaneous transmission on the at least two sets of pre-configured resources, the network device side determines which set of configured resources the terminal specifically selects at the time of the collision to transmit uplink data according to a pre-specified principle (the appointed information between the terminal and the network device side), and other terminals do not use the resources, and the network device side can dispatch the resources to other terminals so as to avoid resource waste.

A terminal side:

In this example, the terminal determines the pre-configured resources specifically used at the time of the conflict according to the agreed information with the base station, for example, the selection principle of the terminal is agreed in the protocol if the terminal has at least two sets of pre-configured resources conflicting.

Such as:

always using the pre-configured resource with the smallest number;

the pre-configured resource with the shortest period is always used.

Example 3: for the above Option 3.1;

network equipment side:

If the terminal has at least two sets of pre-configured resources at the same time and the terminal capability does not support simultaneous transmission on the at least two sets of pre-configured resources, the network device side sends indication information to the terminal and informs the terminal to determine the pre-configured resources specifically used at the conflict time according to the indication information of the network device.

The indication information may use RRC signaling, and the content of the indication information may have two forms:

the indication information is pre-configured resource identification information to be used specifically when the information conflicts, such as a pre-configured resource number;

A terminal side:

the terminal needs to report capability indication information to the network device to indicate whether the terminal transmits simultaneously on the same BWP at the same time. The BWP may be embodied in the form of BWP or in the form of bandcombination (that is, the bandcombination includes only one band, that is, the band where the BWP is located).

In this example, the terminal determines the pre-configured resource specifically used at the time of the collision according to the indication information of the network device. The specific signaling format may be RRC signaling. Specifically, the indication information of the network device side may specifically have two carrying modes:

(1) carried in the RRC signaling carrying the pre-configured resource;

(2) is carried in RRC signaling carrying logical channel configuration information.

Example 4: for the above Option 3.2;

network equipment side:

The indication information may use MAC signaling, i.e., MAC CE. The content of the indication information can be in two forms:

A terminal side:

In this example, the terminal determines the pre-configured resource specifically used at the time of the collision according to the indication information of the network device. The specific signaling format may be MAC signaling, i.e., MAC CE.

To identify the MAC CE, a new LCID needs to be introduced. Specific MAC CE format designs may include the following:

MAC CE design method 1:

The specific format of the MAC CE may be as shown in fig. 3, but is not limited thereto.

MAC CE design method 2:

MAC sub-header: at least comprises an LCID indication field, optionally an L field, and redundant bit positions can be set as a reserved field R; and is

For a specific format example of the MAC CE, taking an example that the terminal has at most three logical channels to support using the preconfigured resources, the specific format example can be shown in fig. 4, but is not limited thereto.

MAC CE design method 1:

MAC CE: and carrying priority indication information corresponding to the conflicted pre-configured resource identifiers in sequence according to the sequence of the pre-configured resource identifiers, wherein redundant bit positions can be set as a reserved domain R. The pre-configured resource causing the collision may be a pre-configured resource actually configured by the network device for the terminal (at this time, the MAC subheader needs to include the L field), or a maximum number of pre-configured resource sets allowed to be configured for the terminal by the network device (at this time, the MAC subheader does not need to carry the L field).

As for the specific format of the MAC CE, the terminal can support at most 8 sets of preconfigured resources as shown in fig. 5, but not limited thereto.

MAC CE design method 2:

Regarding the specific format of the MAC CE, taking as an example that the terminal supports at most 8 sets of preconfigured resources, an 8-bit bitmap can be used, as shown in fig. 6, where CG is shown in the figure_iIdentifying the ith set of preconfigured resources, assuming CG₃And CG₇For the pre-configured resource configured for the terminal at present, the CG in bitmap₃And CG₇Corresponding CG_iMay be set to 1 and the rest to 0. Where CG represents a configuration granted Configured grant.

MAC CE design method 3:

MAC CE: it is necessary to prioritize the logical channels respectively configuring different pre-configured resources. Therefore, in the MAC CE, a logical channel identifier, a bitmap indication field corresponding to the logical channel, and priority indication information of the preconfigured resource whose bitmap indication is 1 need to be configured for each logical channel, and redundant bit positions may be set as a reserved field R; the bitmap indication field corresponding to the logical channel is used to indicate which sets of priority indication information of the preconfigured resources are included in the current MAC CE for the logical channel (specifically, the bitmap indication field corresponding to the logical channel includes at least two bits, and each bit is used to indicate whether the current MAC CE includes the priority indication information of the preconfigured resources associated with the bit for the logical channel).

For the specific format of MAC CE, the terminal is the mostFor example, multiple sets of 8 preconfigured resources are supported, and an 8-bit bitmap can be used, as shown in fig. 7, where CG is shown in the figure_iIdentifying the ith set of preconfigured resources, and assuming that there are two sets of preconfigured resources currently, CG₀And CG₃For the pre-configured resource configured for the terminal at present, the CG in bitmap₀And CG₃Corresponding CG_iMay be set to 1 and the rest to 0. For LCID₀For example, the priority of two sets of pre-configured resources, such as CG, is configured₀And CG₃Are 000 and 001, respectively; for LCID₁For example, CG configures priorities of two sets of pre-configured resources corresponding to the two sets of pre-configured resources respectively₀And CG₃Are 001 and 000, respectively.

Example 5: for Option 3.3 above;

network equipment side:

The indication information can use physical layer signaling, and the content of the indication information can have two forms:

A terminal side:

In this example, the terminal determines the pre-configured resource specifically used at the time of the collision according to the indication information of the network device. The specific signaling format may be physical layer control signaling.

If there is only a Type2 Type of preconfigured resource, the indication information may be carried in PDCCH signaling activated by the preconfigured resource. However, if the preconfigured resources include both Type1 preconfigured resources and Type2 preconfigured resources, then it is preferable to introduce a separate physical layer control signaling to carry the indication information.

As can be seen from the above, the solution provided in the embodiment of the present invention can solve the problem of how the terminal selects which set of pre-configured resources is specifically used when there are at least two sets of pre-configured resources at the same time and there is a collision in the time domain for the terminal that supports only one TB transmission on one BWP at the same time.

step 81: at least two sets of pre-configured resources configured on one frequency band resource for the terminal;

Specifically, the indication information is identification information of a pre-configured resource that needs to be used when a collision occurs to a pre-configured resource configured by the terminal on one frequency band resource (embodiment form one); or the indication information is a priority usage order of pre-configured resources configured for the terminal and conflicting when the pre-configured resources on one frequency band resource conflict (embodiment two).
