In the overlapping portion, data is granted for transmission using the first resource at 220.

It should be understood that the method of the embodiment of the present application is not limited to the scenario in which multiple dynamically scheduled resource grants have overlapping, but may also be applied to the following scenario: the resource grant of dynamic scheduling and the resource grant of semi-static scheduling are overlapped, the resource grants of a plurality of semi-static scheduling are overlapped, the resource grant and Uplink Control Information (UCI) are overlapped, the UCI and the UCI are overlapped, the resource grant and MAC Control unit (CE) are overlapped, the data and MAC CE are overlapped, the UCI and the MAC CE are overlapped, and the logical channel and the MAC CE are overlapped.

Wherein the UCI may be at least one of: hybrid Automatic Repeat Request (HARQ) feedback, Channel-State Information Reference Signal (CSI-RI), and Scheduling Request (SR).

In this embodiment of the present application, the resource grant may be an uplink resource grant, where the resource grant is used for uplink data transmission, or may be a downlink resource grant, where the resource grant may be used for downlink data transmission.

Wherein, the multiple resource grants having overlapping parts can be understood as: the plurality of resource grants have overlapping portions in the time domain, the overlapping portions being overlapping portions in the time domain. Alternatively, the plurality of resource grants having an overlapping portion may refer to the plurality of resource grants having an overlapping portion in the frequency domain, the overlapping portion being an overlapping portion in the frequency domain. Or, it may refer to that the plurality of resource grants have an overlapping portion (i.e., a portion where both the time domain and the frequency domain overlap) on the time-frequency domain, which is an overlapping portion on the time-frequency domain.

Having overlapping parts for multiple resource grants can be understood as: the multiple resource grants may overlap in whole or in part.

Optionally, in the overlapping part, the communication device may transmit only data carried on the first resource grant using the first resource grant; or, the first resource authorization may also be utilized to transmit data carried on the first resource authorization and data carried on other resource authorizations besides the first resource authorization; or, if there is no data for transmission of the first resource grant, in the overlapping portion, the first resource grant may be used to transmit data carried on other resource grants. Wherein the other resource grants mentioned in the foregoing belong to the plurality of resource grants. The data carried on the resource grant includes a resource grant allocated by the base station for one or more data transmissions during scheduling. For example, the base station schedules the xth grant to transmit URLLC service, and the base station schedules the yth grant to transmit eMBB service, then the communication device transmits URLLC service and/or eMBB service by using the xth grant.

Optionally, in this embodiment of the present application, Hybrid Automatic Repeat Request (HARQ) process numbers corresponding to each of the multiple resource grants are different.

Optionally, in this embodiment of the present application, Hybrid Automatic Repeat Request (HARQ) process numbers corresponding to at least two resource grants in the multiple resource grants are the same.

In determining the first resource grant, in one implementation, the communication device may randomly select the first resource grant among a plurality of resource grants.

In another implementation, the communication device may determine the resource grant of the first transmission or the resource grant of the last transmission as the first resource grant.

In another implementation, a communication device may determine a first resource grant based on a first condition.

Optionally, the first condition may be specified by a protocol, preset on the terminal device, or may be pre-configured by the network device to the terminal device, for example, the network device may send Radio Resource Control (RRC) signaling to the terminal device, where the RRC signaling indicates the first condition, so that the terminal device may acquire the first condition based on the RRC signaling.

The first condition is explained in detail below.

In the present embodiment, the first condition may include, but is not limited to, at least one of the following conditions: a transmission order of the resource grant, a priority of the resource grant, an attribute of the resource grant, whether the resource grant is used for retransmission, information of a Logical Channel corresponding to the resource grant, scrambling of a physical Channel for scheduling the resource grant, a service borne by the resource grant, scrambling of the resource grant, a Logical Channel priority available for the resource grant, an identifier of the resource grant, a Logical Channel Priority (LCP) restriction, a Logical Channel identifier or Logical Channel group identifier to be transmitted, a Logical Channel priority or Logical Channel group priority to be transmitted, a service identifier or priority to be transmitted, a specific Logical Channel or Logical Channel group identifier, a specific Logical Channel or Logical Channel group priority, a service identifier or priority borne by the resource grant, a Logical Channel group priority restriction of the resource grant, a specific service identifier or priority, a retransmission request, The method comprises the steps of identifying a logical channel identifier or a logical channel group identifier corresponding to resource authorization to be transmitted, a logical channel priority or a logical channel group priority corresponding to resource authorization to be transmitted, a service identifier or a priority corresponding to resource authorization to be transmitted, a specific logical channel or a logical channel group identifier corresponding to resource authorization, a specific logical channel or a logical channel group priority corresponding to resource authorization, a specific service identifier or a priority corresponding to resource authorization, and a service identifier or a priority borne by/corresponding to resource authorization.

Optionally, the level of resource authorization may be preset on the communication device. Alternatively, the level of resource authorization may be network device indicated.

The priority indication information of resource authorization can be understood as: the resource grants themselves are not ranked, and the indication information may indicate which resource grant has a higher priority, so that the indicated resource grant may be determined to have the highest priority based on the indication information. Alternatively, the network device may determine the priority of the plurality of resource grants, and then the network device may transmit indication information indicating the priority of the resource grants to the terminal device. For example, there is no hierarchical division among resource grant 1, resource grant 2, and resource grant 3, and the terminal device receives the indication information indicating that the priority of resource grant 2 is the highest, the terminal device may determine that resource grant 2 has the highest priority among the 3 resource grants.

The specific resource authorization is: and finally receiving and corresponding or matching the resource authorization of the specific logical channel, or finally indicating and corresponding or matching the resource authorization of the specific logical channel, or finally scheduling and corresponding or matching the resource authorization of the specific logical channel, or finally acquiring and corresponding or matching the resource authorization of the specific logical channel, or finally activating and corresponding or matching the resource authorization of the specific logical channel, or finally arriving and corresponding or matching the resource authorization of the specific logical channel.

Optionally, the priority of the resource grant corresponding to the physical layer control information or channel indicating the resource grant, which arrives at the user last, may be higher than the priority of other resource grants in the plurality of resource grants. Or, the priority of the resource grant corresponding to the last physical layer control information or channel indicating the resource grant, which is indicated to the user, may be higher than the priority of other resource grants in the plurality of resource grants.

The resource grant corresponding to the physical layer control information or channel indicating the resource grant may be understood as: if the physical layer control information or the channel indicates the resource grant 1, the physical layer control information or the channel indicating the resource grant 1 corresponds to the resource grant 1.

It should be noted that, if the first condition includes the transmission sequence of the resource grants, the first resource grant may be the resource grant that is received first or obtained first or indicated first or scheduled first or activated first or arrived first among the plurality of resource grants, or the physical layer control information or channel indicating the first resource grant arrives first or indicated first to the user among the physical layer control information or channels indicating the plurality of resource grants.

Alternatively, a particular resource grant of the plurality of resource grants may be a first resource grant. E.g. specific types of resource grants, specific indicated manners of resource grants, resource grants for specific traffic/logical channel transmissions, specific properties of resource grants, specific indicated resource grants. Illustratively, if the particular traffic is URLLC traffic, the first resource grant may be a resource grant for the URLLC traffic among the plurality of resource grants. Wherein the plurality of resource grants may be a plurality of pre-configured resource grants.

It should be understood that, in the embodiment of the present application, if a plurality of dynamically scheduled resource grants have overlapping portions, the communication device may determine, according to the first condition, a first resource grant for transmitting data in the overlapping portions, and may also determine, according to the first condition, a third resource grant for transmitting data in the non-overlapping portions. An implementation of the communication device determining the third resource grant to transmit data in the non-overlapping portion according to the first condition may refer to an implementation of the communication device determining the first resource grant according to the first condition. Here, for the sake of brevity of the contents, no further description is given.

It should also be understood that in the embodiments of the present application, if a plurality of dynamically scheduled resource grants have an overlapping portion, the communication device may determine a resource grant to be used according to the first condition among the plurality of dynamically scheduled resource grants. If resource grant 1 and resource grant 2 overlap, the communication device may determine whether resource grant 1 or resource grant 2 is to be selected based on a first condition.

It should also be understood that in the embodiment of the present application, if there is a resource conflict or collision, the communication device may determine, according to the first condition, the resource authorization to be used among the plurality of conflicted or collided resources. If UCI 1 and UCI 2 collide, the communication device may determine whether UCI 1 or UCI 2 is to be selected according to a first condition.

In a possible embodiment, the communication device may determine the second resource grant, and then send the second resource grant to the HARQ entity by using a Media Access Control (MAC) layer, and in the second resource grant, determine the first resource grant.

Wherein the second resource grant belongs to the plurality of dynamically scheduled resource grants mentioned above, and the second resource grant comprises at least one resource grant.

Alternatively, the second resource grant may be determined at the MAC layer.

In the process that the communication device sends the second resource grant to the HARQ entity by using the MAC layer, as an example, at least one of the second resource grants may be sent to the HARQ entity by using the MAC layer.

Illustratively, the communication device may utilize the MAC layer to transmit all of the second resource grants to the HARQ entity.

For another example, the communication device may send any of the second resource grants to the HARQ entity using the MAC layer. For example, if the communication device determines that the second resource grant is received by the MAC layer, the MAC layer only receives one resource grant, and other resource grants have not yet arrived, the communication device may send the received one resource grant to the HARQ entity by using the MAC layer.

For another example, the communication device may send any of the second resource grants to the HARQ entity using the MAC layer. For example, if the MAC layer receives at least one resource grant, the communication device determines, by using the MAC layer, one or more resource grants among the plurality of resource grants as a second resource grant, and the communication device may send the second resource grant to the HARQ entity by using the MAC layer. Wherein, it can be understood that at least one of the plurality of resource grants received by the MAC layer is transmitted to the HARQ entity.

As another example, if the second resource grant includes only one resource grant at the current time, the MAC layer may not transmit the second resource grant to the HARQ entity.

Optionally, the second resource grant at the current time only includes one resource grant, which may be understood as: the second resource authorization determined by the communication device by using the MAC layer only comprises one resource authorization; or, the communication device receives only one resource authorization by using the MAC layer at the current time, and the other resource authorizations do not arrive yet.

In the process of the communication device determining the second resource grant using the MAC layer, the communication device may randomly select the second resource grant, as an example.

As another example, the communication device may determine all of the plurality of dynamically scheduled resource grants mentioned above as the second resource grant.

As another example, the communication device may determine the second resource grant based on the first condition. It should be understood that the implementation of the communication device determining the second resource authorization according to the first condition may refer to the implementation of the content communication device determining the first resource authorization according to the first condition, which is not described herein too much for the sake of brevity of the content.

The second resource grant may be determined to be the first resource grant if the second resource grant includes one resource grant.

If the second resource grant includes multiple resource grants but only one resource grant is transmitted to the HARQ entity, the transmitted resource grant may be determined to be the first resource grant.

If the second resource grant sent by the communication device to the HARQ entity by using the MAC layer includes at least two resource grants, the communication device may determine the first resource grant in the second resource grant by using the MAC layer or the physical layer.

It should be noted that, the communication device utilizes the MAC layer or the physical layer, and the implementation manner of determining the first resource grant in the second resource grant may refer to the implementation manner of determining the first resource grant by the communication device in the foregoing.

Illustratively, the communication device may determine the last resource grant received by the HARQ process as the first resource grant using the MAC layer or the physical layer.

For another example, the communication device may determine the first resource grant received by the HARQ process as the first resource grant using the MAC layer or the physical layer.

As another example, the communication device may determine the first resource grant among the second resource grants according to a first condition using a MAC layer or a physical layer.

In this embodiment of the application, if the communication device utilizes the physical layer, and determines the first resource grant in the second resource grant according to the first condition, the method 200 may further include: the communication device receives third indication information by using a physical layer, wherein the third indication information is used for indicating a first condition.

Alternatively, the third indication information may come from other protocol layers or network devices.

Optionally, the content included in the first condition may be different from the content included in the first condition in which the communication device determines that the first resource is authorized. For convenience of description, the first condition is referred to herein as a second condition.

For example, the first condition may include a priority of the resource grant and an attribute of the resource grant, and the second condition may include traffic of the resource grant bearer.

For another example, the first condition may include a transmission order of the resource grants and information of logical channels corresponding to the resource grants, and the second condition may include whether the resource grants are used for retransmission and scrambling of the resource grants.

Alternatively, the contents included in the first condition and the second condition are the same, but the conditions that the first condition and the second condition need to satisfy may be different.

For example, the first condition and the second condition both include the property of the resource grant and the scrambling of the resource grant, but the subcarrier spacing set in the first condition is 15KHz and 60KHz, and the subcarrier spacing list set in the second condition is 30 KHz.

For another example, the first condition and the second condition both include scrambling of the resource grant, but the specific RNTI in the first condition is the CS-RNTI, and the specific RNTI in the second condition is the TC-RNTI.

Optionally, in this embodiment of the present application, the communication device may indicate at least one resource grant of the second resource grants to the physical layer by using the MAC layer. For example, all of the second resource grants may be indicated to the physical layer, or any of the second resource grants may be indicated to the physical layer.

In one implementation, if the communication device determines the first resource grant in the second resource grant by using the MAC layer, after the communication device determines the first resource grant by using the MAC layer, in one possible case, the communication device may send first indication information to the physical layer by using the MAC layer, where the first indication information is used to indicate the determined first resource grant.

In another possible scenario, the communication device may send a first resource grant to the physical layer using the MAC layer.

In another implementation, if the communication device determines the first resource grant in the second resource grant by using the physical layer, as an example, the communication device may receive second indication information by using the physical layer, where the second indication information may be used to indicate the first resource grant, and/or the second indication information may be used to assist the physical layer in determining the first resource grant, and then the communication device may determine the first resource grant by using the physical layer based on the second indication information.

Optionally, the second indication information may be from the MAC layer or from the network device.

Optionally, if the second indication information is used to assist the physical layer to determine the first resource authorization, the second indication information may indicate a service that is carried by each resource authorization in the second resource authorization, may also indicate a priority of each resource authorization in the second resource authorization, and may also indicate whether the resource authorization that the communication device receives the resource authorization sent by the HARQ entity at the current time through the physical layer preempts the resource authorization that the HARQ entity sends at the last time, and of course, may also indicate whether the priority that the communication device receives the resource authorization that the HARQ entity sends at the current time through the physical layer is higher than the priority that the resource authorization that the HARQ entity sends at the last time is received.

Alternatively, the second indication information may be the same as the first indication information.

It should be understood that the term "and/or" herein is merely one type of association relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

It should also be understood that, in the embodiments of the present application, "first", "second", and "third" are merely used to distinguish different objects, but do not limit the scope of the embodiments of the present application.

Optionally, in this embodiment of the present application, the method 200 may further include: and determining whether to transmit HARQ information corresponding to the resource grant to the HARQ entity in the overlapping part.

Alternatively, the communication device may utilize the physical layer to randomly select one of the plurality of dynamically scheduled resource grants as the first resource grant.

Alternatively, the communication device may determine, using the physical layer, a first resource grant among the plurality of dynamically scheduled resource grants based on a first condition.

It should be noted that the content included in the first condition may be different from the content included in the first condition in which the communication device determines the first resource authorization. For convenience of description, the first condition herein will be referred to as a third condition.

For example, the first condition may include a priority of the resource grant and an attribute of the resource grant, and the third condition may include whether the resource grant is used for retransmission and scrambling of the resource grant.

Alternatively, the contents included in the first condition and the third condition are the same, but the conditions that the first condition and the third condition need to satisfy may be different.

For example, the first condition and the third condition both include the property of the resource grant and the scrambling of the resource grant, but the subcarrier spacing set in the first condition is 15KHz and 60KHz, and the subcarrier spacing list set in the third condition is 30 KHz.

For another example, the first condition and the third condition both include scrambling of the resource grant, but the specific RNTI in the first condition is the CS-RNTI, and the specific RNTI in the third condition is the TC-RNTI.

Optionally, the third condition may be a default configuration or may be from a network device.

It should be noted that, in this embodiment, the communication device utilizes the physical layer, and the implementation process of determining the first resource grant in the plurality of dynamically scheduled resource grants is not participated in the MAC layer at all times. It should be further noted that, in the embodiment of the present application, the communication device may determine the first resource grant by using the MAC layer and the physical layer simultaneously.

As another possible embodiment, the communication device may determine the first resource grant among a plurality of dynamically scheduled resource grants using a MAC layer.

As an example, the communication device can utilize the MAC layer to randomly select one of the plurality of dynamically scheduled resource grants as the first resource grant.

As another example, the communications device may determine, using the MAC layer, a first resource grant among a plurality of dynamically scheduled resource grants according to a first condition.

It should be noted that the content included in the first condition may be different from the content included in the first condition in which the communication device determines the first resource authorization. For convenience of description, the first condition herein will be referred to as a fourth condition.

For example, the first condition may include an attribute of the resource grant, and the fourth condition may include a transmission order of the resource grant.

Alternatively, the contents included in the first condition and the fourth condition are the same, but the conditions that the first condition and the fourth condition need to satisfy may be different.

For example, the first condition and the fourth condition both include the property of the resource grant and the scrambling of the resource grant, but the subcarrier spacing set in the first condition is 15KHz and 60KHz, and the subcarrier spacing list set in the fourth condition is 30 KHz.

For another example, the first condition and the fourth condition both include scrambling of the resource grant, but the RNTI specified in the first condition is the CS-RNTI, and the RNTI specified in the fourth condition is the TC-RNTI.

Optionally, the fourth condition may be a default configuration or may be from a network device.

Optionally, in this embodiment of the present application, when multiple resource grants have overlapping portions, the communication device may further determine a third resource grant for transmitting data. The communication device authorizes transmission of data with the third resource.

Optionally, the third resource grant may be the same as the first resource grant. At this time, when the plurality of resource grants have overlapping portions, the communication device may transmit data using the first resource grant.

Optionally, the third resource grant may be different from the first resource grant. At this time, when the plurality of resource grants have overlapping portions, the communication device may transmit data with the first resource grant from the overlapping position, or the communication device transmits data using only the first resource grant and does not transmit data in the non-overlapping position, or the communication device transmits data using the first resource grant in the overlapping position and transmits data using the other resource grant in the non-overlapping position.

Wherein the communication device may determine the third resource grant using the physical layer and/or the MAC layer.

As one example, the communication device may randomly select a third resource grant among the plurality of resource grants.

As another example, the communication device may determine the resource grant of the first transmission or the resource grant of the last transmission as the third resource grant.

As another example, the communication device may determine the first scheduled/arriving resource grant or the last scheduled/arriving resource grant as the third resource grant.

As another example, the communication device may determine the third resource grant based on the first condition. The implementation of the communication device determining the third resource grant according to the first condition may refer to the implementation of the communication device determining the first resource grant according to the first condition. Here, for the sake of brevity of the contents, no further description is given.
