Description

MCS configuration method, device and system

Technical Field

The present application relates to the field of communication technology, and in particular to an MCS configuration method, device and system.

Background Art

In the 5th Generation (5G) communication system, the terminal can transmit uplink periodic service data through uplink configured grant (CG) resources. At present, the scheduling process of uplink CG resources is as follows: the base station configures the relevant parameters of the CG resources, such as the CG period, through the radio resource control layer (RRC) signaling, and activates the CG resources through RRC signaling or downlink control information (DCI), and then the terminal can periodically reuse the activated CG resources for uplink transmission according to the received CG configuration.

With the development of communication technology, in order to adapt to some services that require higher uplink transmission rates, such as augmented reality (AR) services in extended reality (eXtended Reality, XR), a solution to enhance uplink CG transmission has been proposed. For example, for unlicensed frequency bands, it is allowed to configure multiple consecutive uplink CG transmission opportunities within one CG cycle, such as configuring multiple physical uplink shared channels (PUSCH).

However, there is currently no modulation and coding scheme (MCS) configuration method for the scenario where there are multiple CG transmission opportunities within a CG cycle. If the existing MCS configuration method is used to configure the MCS of multiple CG transmission opportunities within the CG cycle, the flexibility is low.

Summary of the invention

The embodiments of the present application provide an MCS configuration method, device and system for improving the flexibility of configuring the MCS for multiple CG transmission opportunities within a CG cycle period.

To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

In the first aspect, an MCS configuration method is provided, which can be executed by a terminal or by a module (such as a processor, a chip, or a chip system, etc.) applied to the terminal. The following is an example of a terminal executing the method, and the method includes: the terminal obtains first configuration information and first indication information, the first configuration information is used to configure the modulation coding strategy MCS, and the first indication information is used to indicate that the MCS is applied to configure multiple CG transmission opportunities in the authorized CG cycle period. Then, the terminal transmits data on the CG transmission opportunity within the CG cycle period according to the MCS.

Based on the MCS configuration method provided in the embodiment of the present application, the MCS can be configured through the first configuration information, and the configured MCS can be applied to multiple CG transmission opportunities within the CG cycle period indicated by the first indication information. Compared with the existing solution that multiple CG transmission opportunities within the CG cycle period can only correspond to the same pre-configured MCS, the first configuration information can configure the MCS according to actual needs, for example, one or more different MCSs can be configured. Therefore, this solution can improve the flexibility of configuring the MCS corresponding to multiple CG transmission opportunities within the CG cycle period.

In combination with the above-mentioned first aspect, in a possible design, the terminal transmits data at the CG transmission opportunity within the CG cycle period according to the MCS, including: the terminal transmits data at the CG transmission opportunity within the CG cycle period according to one MCS among multiple MCSs.

Based on this solution, the first configuration information can configure multiple MCSs, and the CG transmission timing within the CG cycle period can correspond to one of the multiple MCSs, thereby improving the flexibility of configuring the MCS.

In a second aspect, an MCS configuration method is provided, which can be executed by a RAN node or by a module (such as a processor, a chip, or a chip system, etc.) applied to the RAN node. The following takes the execution of the method by the RAN node as an example for explanation, and the method includes: the RAN node sends first configuration information and first indication information, the first configuration information is used to configure the modulation coding strategy MCS, and the first indication information indicates that the MCS is applied to configure multiple CG transmission opportunities in the authorized CG cycle period. Then, the RAN node receives data on the CG transmission opportunity within the CG cycle period according to the MCS.

Based on the communication method provided in the embodiment of the present application, the MCS can be configured through the first configuration information, and the configured MCS can be applied to multiple CG transmission opportunities within the CG cycle period indicated by the first indication information. Compared with the existing solution that multiple CG transmission opportunities within the CG cycle period can only correspond to the same pre-configured MCS, the first configuration information can configure one or more different MCSs according to actual needs. Therefore, this solution can improve the flexibility of configuring the MCS corresponding to multiple CG transmission opportunities within the CG cycle period.

In combination with the second aspect above, in a possible design, the RAN node receives data at the CG transmission opportunity within the CG cycle period according to the MCS, including: the RAN node receives data at the CG transmission opportunity within the CG cycle period according to one MCS among multiple MCSs.

Based on this solution, the first configuration information can configure multiple MCSs, and the CG transmission timing within the CG cycle period can correspond to one of the multiple MCSs, thereby improving the flexibility of configuring the MCS.

In combination with the first aspect or the second aspect, in a possible design, at least two CG transmission opportunities within the CG cycle period correspond to a first common MCS among multiple MCSs. Based on this solution, the flexibility of configuring the MCS corresponding to multiple CG transmission opportunities within the CG cycle period can be improved.

In combination with the first aspect or the second aspect above, in a possible design, within the CG cycle period, CG transmission opportunities other than at least two CG transmission opportunities correspond to MCSs other than the first common MCS in multiple MCSs. Based on this solution, the flexibility of configuring the MCSs corresponding to multiple CG transmission opportunities within the CG cycle period can be improved.

In combination with the first aspect or the second aspect above, in a possible design, in the CG cycle period, in addition to at least two CG transmission opportunities, at least two CG transmission opportunities correspond to a second common MCS among multiple MCSs. Based on this solution, the flexibility of configuring the MCS corresponding to multiple CG transmission opportunities within the CG cycle period can be improved.

In combination with the first aspect or the second aspect above, in a possible design, multiple CG transmission opportunities within the CG cycle period correspond one-to-one to multiple MCSs.

Based on this solution, multiple CG transmission opportunities within the CG cycle period can correspond to multiple MCSs respectively, and the configuration of MCS is more independent and flexible.

In combination with the above-mentioned first aspect or second aspect, in a possible design, the first configuration information configures indexes of multiple MCSs.

Based on this solution, the first configuration information can directly configure the indexes of multiple MCSs to configure the MCS. Compared with the existing protocol, the changes are relatively small, and it can be better applied to the existing communication system, while improving the flexibility of MCS configuration.

In combination with the above-mentioned first aspect or second aspect, in a possible design, the first configuration information configures the index of a first MCS among multiple MCSs, and the offset of the indexes of other MCSs among the multiple MCSs relative to the index of the first MCS.

Based on this solution, the first configuration information can configure the index of other MCSs by configuring an offset relative to the index of the first MCS, which can reduce signaling overhead.

DETAILED DESCRIPTION

In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is first given as follows.

1. MCS:

MCS defines the modulation scheme and coding scheme corresponding to the transmission resource. There are currently 32 MCSs, which are distinguished by different indexes and pre-configured in the terminal in the form of a table. The specific form can refer to the existing protocol. The network side can indicate the index of the MCS through the 5-bit mcsAndTBS field in the DCI, thereby configuring the MCS corresponding to the transmission resource. For example, assuming that the bit sequence of the mcsAndTBS field is 00001, it means that the MCS with an index of 1 is configured for the transmission resource.

2. Uplink CG transmission:

Uplink CG transmission is suitable for transmitting periodic uplink service data. The base station only needs to schedule CG resources once, and the terminal can perform uplink transmission periodically based on the scheduled CG resources.

Currently, there are two types of CG: type 1 and type 2. For uplink transmission, type 1 CG includes the following steps:

1. The base station configures relevant parameters of CG resources, such as CG period, specific time-frequency domain resources, etc. through RRC signaling. Optionally, the base station can configure parameters of multiple CG resources (such as different CG periods).

2. The media access control (MAC) entity of the terminal determines the periodic transmission occasion (occasion) (hereinafter referred to as CG transmission occasion) corresponding to the CG resource according to the obtained CG configuration, such as the periodic time slot or symbol, and transmits uplink data at the CG transmission occasion.

It should be noted that in the embodiments of the present application, the CG transmission opportunity can also be understood as a CG uplink resource, such as a CGPUSCH resource (or called a CGPUSCH transmission opportunity), etc. In the following introduction, the CG transmission opportunity and the CG uplink resource can be replaced with each other.

3. After the service transmission is completed, the base station sends DCI to deactivate the CG configuration and release the CG resources.

For uplink transmission, the CG scheduling process of type 2 includes the following steps:

1. The base station configures relevant parameters of CG resources, such as CG period, etc. through RRC signaling. Optionally, the base station can configure parameters of multiple CG resources (such as different CG periods).

2. The base station activates CG transmission through DCI and indicates specific time-frequency domain resources through the resource allocation field in DCI, that is, activates the corresponding CG resources through DCI.

3. The MAC entity of the terminal determines the CG transmission timing corresponding to the activated CG resources based on the acquired CG configuration, and transmits uplink data at the CG transmission timing.

4. After the service transmission is completed, the base station sends DCI to deactivate the CG configuration and release the CG resources.

3. Enhanced solution for uplink CG transmission:

In order to meet the needs of some periodic services with large data volumes, a solution to enhance CG transmission is currently proposed, which allows multiple CG transmission opportunities to be configured within a CG cycle period. For example, as shown in Figure 1, multiple PUSCHs can be configured within a CG cycle period. The duration of the CG cycle period is equal to the CG cycle.

However, the existing MCS configuration method can only indicate one of the pre-configured MCSs. That is to say, if the existing MCS configuration method is applied to multiple CG transmission opportunities within a CG cycle period, these multiple CG transmission opportunities will correspond to the same pre-configured MCS, which greatly reduces the flexibility. Based on this problem, the embodiments of the present application provide a communication method, device and system, which can improve the flexibility of configuring the MCS of multiple CG transmission opportunities within the same CG cycle period.

The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. Among them, in the description of the present application, unless otherwise specified, "/" indicates that the objects associated before and after are in an "or" relationship, for example, A/B can represent A or B; "and/or" in the present application is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and/or B, which can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. And, in the description of the present application, unless otherwise specified, "multiple" refers to two or more than two. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c can represent: a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, c can be single or multiple. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with substantially the same functions and effects. Those skilled in the art will understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily limit the differences. At the same time, in the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design solutions. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner for ease of understanding.

FIG2 is a possible, non-limiting system schematic diagram provided by an embodiment of the present application. As shown in FIG2 , a communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (such as 110a and 110b in FIG2 , collectively referred to as 110) and at least one terminal (such as 120a-120j in FIG2 , collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay equipment and/or wireless backhaul equipment (not shown in FIG2 ). Terminal 120 is connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 wirelessly or by wire. The core network device in core network 200 and RAN node 110 in RAN 100 may be different physical devices, or may be the same physical device integrating core network logical functions and radio access network logical functions.

RAN 100 may be a cellular system related to the 3rd Generation Partnership Project (3GPP), for example, a long term evolution (LTE) system, a 5th generation mobile communication technology (5G) system, or a future-oriented evolution system (e.g., a 6G mobile communication system). RAN 100 may also be an open access network (openRAN, O-RAN or ORAN), a cloud radio access network (CRAN), or a wireless fidelity (WiFi) system. RAN 100 may also be a communication system that is a fusion of two or more of the above systems. In addition, the term "system" may be interchangeable with "network".

It should be noted that the network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

Taking the interaction between the RAN node 110 and any terminal 120 shown in Figure 2 as an example, in the communication method provided in the embodiment of the present application, the RAN node 110 sends first configuration information and first indication information to the terminal 120, the first configuration information is used to configure the MCS, and the first indication information indicates that the MCS is applied to multiple CG transmission opportunities in the CG cycle period. After the terminal 120 obtains the first configuration information and the first indication information, it transmits data at the CG transmission opportunity within the CG cycle period according to the MCS. Correspondingly, the RAN node transmits data at the CG transmission opportunity within the CG cycle period according to the MCS. The specific implementation and technical effects of this scheme will be described in detail in the subsequent method embodiments and will not be repeated here.

The RAN node 110 in the embodiment of the present application may sometimes also be referred to as an access network device, a RAN entity or an access node, etc., and constitutes a part of the communication system to help the terminal achieve wireless access. The multiple RAN nodes 110 in the communication system 10 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative. For example, the network element 120i in FIG. 2 may be a helicopter or a drone, which may be configured as a mobile base station. For the terminal 120j that accesses the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b in FIG. 2 may be understood as communication devices with base station functions, and the network elements 120a-120j may be understood as communication devices with terminal functions.

In one possible scenario, the RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The RAN node may be a macro base station (such as 110a in FIG. 2 ), a micro base station or an indoor station (such as 110b in FIG. 2 ), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an onboard device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node in the present application may also be a logical node, a logical module or software that can implement all or part of the RAN node functions.

In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

The terminal in the embodiments of the present application may also be referred to as a terminal device, user equipment (UE), a mobile station, a mobile terminal, etc. The terminal can be widely used in various scenarios, for example, vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of things (IoT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

The memory 303 is used to store computer-executable instructions for executing the solution of the present application, and the execution is controlled by the processor 301. The processor 301 is used to execute the computer-executable instructions stored in the memory 303, thereby implementing the method provided in the following embodiments of the present application.

The first configuration information is used to configure MCS; the first indication information is used to indicate that the MCS is applied to multiple CG transmission opportunities in the CG cycle period.

S402, the terminal transmits data at the CG transmission opportunity within the CG cycle period according to the MCS. Correspondingly, the RAN node receives data at the CG transmission opportunity within the CG cycle period according to the MCS.

It should be noted that in the embodiments of the present application, "sending information to the terminal" in the present application or the related illustrations in the accompanying drawings can be understood as the destination end of the information is the terminal. It can include sending information to the terminal directly or indirectly. "Receiving information from the terminal" or "receiving information from the terminal", or the related illustrations in the accompanying drawings can be understood as the source end of the information is the terminal, which can include receiving information from the terminal directly or indirectly. The information may be processed as necessary between the source end and the destination end of the information transmission, such as format changes, etc., but the destination end can understand the valid information from the source end. Similar expressions in the present application can be understood similarly, such as "sending information to the RAN node" or "receiving information from the RAN node" or "receiving information from the RAN node", etc., which will not be repeated here.

It should be noted that in the embodiments of the present application, "the RAN node sends information" can be the RAN node sending information to another device, or the logical module of the RAN node sending information to other logical modules of the RAN node. Further, combined with the above explanation of "sending information to the terminal", the step of "the RAN node sending information to the terminal" can be understood as the source of the information is the RAN node, and the destination of the information is the terminal. The RAN node can send information directly to the terminal, or the logical module of the RAN node can send information to the terminal through other logical modules of the RAN node (indirectly). Similar expressions in this application can be understood similarly and will not be repeated here.

The following is a detailed description of steps S401-S402.

In S401, the first configuration information may configure one or more MCSs. If the first configuration information configures multiple MCSs, the multiple MCSs may be different or the same.

Wherein, different MCS means that at least one of the modulation scheme and the coding scheme included in the MCS is different. Same MCS means that the modulation scheme and the coding scheme included in the MCS are the same.

Optionally, the first configuration information may configure an index of the MCS, and may also configure a modulation scheme and a coding scheme included in the MCS.

Optionally, the index of the MCS configured by the first configuration information may be the index of a preconfigured MCS. For example, if the terminal preconfigures 4 different MCSs, the first configuration information may configure the indexes of these 4 MCSs. Alternatively, the index of the MCS configured by the first configuration information may also be the index of the MCS configured by the first configuration information itself. For example, the first configuration information configures the modulation schemes and coding schemes respectively included in the 3 MCSs, and configures the indexes of the 3 MCSs respectively.

In a possible implementation, the first configuration information may configure the index of each MCS. For example, assuming that the first configuration information configures two MCSs, the first configuration information may configure the index of one of the MCSs to be 1 and the index of the other MCS to be 2.

In another possible implementation, the first configuration information may configure the index of the first MCS, and configure the offset of the indexes of other MCSs in multiple MCSs relative to the index of the first MCS. The first MCS may be any MCS in multiple MCSs. Optionally, multiple MCSs may be divided into one or more groups, the index of the first MCS in each group may be configured, and the offset of the indexes of other MCSs in each group except the first MCS may be configured relative to the index of the first MCS. The offset may also be replaced by a step size.

Optionally, the first configuration information may respectively configure the offset of the index of other MCSs except the first MCS in each group relative to the index of the first MCS.

Exemplarily, assume that the first configuration information configures 6 MCSs: MCS1, MCS2, MCS3, MCS4, MCS5, and MCS6. Among them, MCS1, MCS2, MCS3, and MCS4 are in the same group, and the first MCS in the group is MCS1. MCS5 and MCS6 are in the same group, and the first MCS in the group is MCS5. For the first group, the first configuration information can configure the index of MCS1 to be 1, and configure the offset of the index of MCS2 relative to the index of MCS1 to be 1, configure the offset of the index of MCS3 relative to the index of MCS1 to be 2, and configure the offset of the index of MCS4 relative to the index of MCS1 to be 3. For the second group, the first configuration information can configure the index of MCS5 to be 2, and configure the offset of the index of MCS6 relative to the index of MCS5 to be 4.

Optionally, if multiple MCSs are divided into multiple groups, and there are at least groups with the same number of MCSs, in at least two groups with the same number of MCSs, the offsets of the indices of other MCSs except the first MCS relative to the index of the first MCS may be unified. In a possible implementation, for at least two groups with the same number of MCSs, the first configuration information may configure the offsets of the indices of other MCSs except the first MCS relative to the index of the first MCS in any one of the groups, and in the group with the same number of MCSs as the group, the offsets of the indices of other MCSs except the first MCS relative to the index of the first MCS in the group may be kept consistent with the group through signaling indication (for example, through the first configuration information or other information indication) or in a predefined manner.

Exemplarily, assume that the first configuration information configures 6 MCSs: MCS1, MCS2, MCS3, MCS4, MCS5 and MCS6. Among them, MCS1, MCS2 and MCS3 are in the same group, and the first MCS in the group is MCS1. MCS4, MCS5 and MCS6 are in the same group, and the first MCS in the group is MCS4. For the first group, the first configuration information can configure the index of MCS1 to be 1, and configure the offset of the index of MCS2 relative to the index of MCS1 to be 1, and configure the offset of the index of MCS3 relative to the index of MCS1 to be 2. For the second group, the first configuration information can configure the index of MCS4 to be 2, and indicate the offset of the index of other MCSs in the second group except MCS4 relative to the index of MCS4, which is unified with the first group, that is, the offset of the index of MCS5 relative to the index of MCS4 is 1, and the offset of the index of MCS6 relative to the index of MCS4 is 2.

In particular, for a group including two MCSs, the offset of the index of another MCS other than the first MCS in each group relative to the index of the first MCS may be the same. For example, assume that the first configuration information configures 4 MCSs: MCS1, MCS2, MCS3, and MCS4. Among them, MCS1 and MCS2 are in the same group, and the first MCS in the group is MCS1. MCS3 and MCS4 are in the same group, and the first MCS in the group is MCS3. In these two groups, the offset of the index of MCS2 relative to the index of MCS1, and the offset of the index of MCS4 relative to the index of MCS3, can both be configured to be 1.

Of course, for groups with the same number of MCSs, the offsets of the index configurations of other MCSs except the first MCS in each group relative to the index of the first MCS in the group may also be different, and the embodiments of the present application do not limit this.

In another possible implementation, multiple MCSs may be divided into one or more groups, the MCSs in each group may be arranged in a certain order, the index of the first MCS in each group may be configured, and the index of the other MCSs other than the first MCS may be configured to be offset from the index of the previous MCS. In this implementation, the first MCS is the first MCS in each group.

Optionally, except for the first MCS in a group, the offsets of the indexes of other MCSs compared to the index of the previous MCS may be the same, or may be increased or decreased in sequence.

For example, assuming that among the MCSs configured by the first configuration information, MCS1, MCS2, MCS3 and MCS4 are in the same group, where MCS1 is the first MCS of the group. The first configuration information configures the index of MCS1 to be 1, and configures the offsets of the indexes of other MCSs relative to the index of the previous MCS to be 1, so the index of MCS2 is 2, the index of MCS3 is 3, and the index of MCS4 is 4. Alternatively, the first configuration information can configure the offsets of the indexes of other MCSs relative to the index of the previous MCS, starting from 1 and increasing by 1 in sequence, so the offset of the index of MCS2 relative to the index of MCS1 is 1, the index of MCS2 is 2, the offset of the index of MCS3 relative to the index of MCS2 is 2, the index of MCS3 is 4, the offset of the index of MCS4 relative to the index of MCS3 is 3, and the index of MCS4 is 7.

Optionally, the first configuration information may configure the MCS in the form of a table. In this scheme, in the table configured by the first configuration information, each row may correspond to one or more MCSs. Exemplarily, it is assumed that the first configuration information configures a table of two rows and two columns, wherein the first column corresponding to the first row may be used to configure MCS1, for example, to configure the index of MCS1 or the modulation and coding scheme included in MCS1, the second column corresponding to the first row is idle (or has no information), and the two columns corresponding to the second row may be used to configure MCS2 and MCS3, for example, the first column corresponding to the second row may be used to configure the index of MCS2 or the modulation and coding scheme included in MCS2, and the second column corresponding to the second row may be used to configure the index of MCS3 or the modulation and coding scheme included in MCS3.

Optionally, if the first configuration information configures the MCS in the form of a table, the maximum number of MCSs corresponding to a row in the table, or the number of columns in the table, may be the maximum number of CG transmission opportunities within the CG cycle period.

Optionally, if the first configuration information configures the MCS in the form of a table, each row in the table may be identified by an index (or referred to as a sequence number).

Optionally, if the first configuration information configures the MCS in the form of a table, each row in the table can be understood as a group of MCSs. Furthermore, each row in the table can be understood as a group of MCSs including a first MCS. The first configuration information can configure the index of the first MCS in each row, and configure the offset of the indexes of other MCSs except the first MCS in each row relative to the index of the first MCS. Alternatively, in each row in the table, the MCS corresponding to the first column can be understood as the first MCS in a group of MCSs (i.e., the first MCS), and the first configuration information can configure the index of the first MCS in each row, and configure the offset of the indexes of other MCSs except the first MCS compared to the index of the previous MCS.

It should be noted that the above is introduced by taking the offset of the index of other MCSs other than the first MCS configured by the first configuration information relative to the index of the first MCS as an example. In the embodiment of the present application, the offset of the index of other MCSs other than the first MCS relative to the index of the first MCS may also be configured by other information, or may be predefined. Similarly, the offset of the index of other MCSs other than the first MCS compared to the index of the previous MCS may also be configured by other information, or may be predefined.

For example, the offset may be configured by other information in the signaling carrying the first configuration information, or may be indicated by the DCI. Optionally, in a type 1 CG scenario, the offset may be configured by the first configuration information or other information in the signaling carrying the first configuration information. In a type 2 CG scenario, the offset may be indicated by the DCI.

In S401, the terminal can determine the MCS configured by the first configuration information based on the first indication information, which can be applied to multiple CG transmission opportunities within the CG cycle period.

Among them, multiple CG transmission opportunities within the CG cycle period can be determined by the terminal based on the CG configuration sent by the RAN node.

Optionally, the first configuration information and the first indication information may be carried in the same signaling. For example, the first configuration information and the first indication information may be carried in the same RRC signaling. Alternatively, the first configuration information and the first indication information may also be carried in different signalings. For example, the first configuration information may be carried in the RRC signaling, and the first indication information may be carried in the DCI.

Optionally, the first indication information may be newly defined information that is different from the existing information. Alternatively, the first indication information may also be existing information with extended functions. For example, the first indication information may be the mcsAndTBS field carried in the DCI, and the function of the field is extended from indicating the index of the pre-configured MCS to indicating that the MCS configured by the first configuration information is applied to multiple CG transmission opportunities in the CG cycle period.

Optionally, the first configuration information may be newly defined information different from existing information. For example, the first configuration information may be a new field in RRC signaling, and an exemplary name of the field may be the mcsAndTBSList field. Alternatively, the first indication information may also be existing information after the function is extended.

It can be understood that, based on the indication of the first indication information, when the first configuration information configures an MCS, multiple CG transmission opportunities within the CG cycle period correspond to this MCS.

In the case where the first configuration information configures multiple MCSs, the multiple MCSs configured by the first configuration information can be fully or partially applied to multiple CG transmission opportunities within the CG cycle period. Based on the indication of the first indication information, one of the multiple MCSs configured by the first configuration information can correspond to one or more CG transmission opportunities in the CG cycle period. Specifically, the terminal can determine which MCSs among the multiple MCSs configured by the first configuration information are applied to multiple CG transmission opportunities within the CG cycle period based on the first indication information, and determine the correspondence between the applied MCS and the multiple CG transmission opportunities within the CG cycle period.

In a possible implementation, the first indication information may directly indicate the index of the MCS applied to the CG cycle period. For example, assuming that the first configuration information configures 5 MCSs, the indexes of these 5 MCSs are 1, 2, 3, 4, and 5. The first indication information indicates index 1 and index 2, which means that among these 5 MCSs, the MCSs with index 1 and index 2 can be applied to multiple CG transmission opportunities within the CG cycle period.

In another possible implementation, the first indication information may indicate the index of a group of MCSs applied to the CG cycle period. In this implementation, the multiple MCSs configured by the first configuration information may be divided into one or more groups, each with a corresponding index. For example, assuming that the first configuration information configures 6 MCSs in a table format, the table includes 3 rows, and the indexes of the 3 rows are 1, 2, and 3. The first indication information indicates index 1, which means that the MCS corresponding to the first row in the table can be applied to multiple CG transmission opportunities within the CG cycle period.

According to the above two situations, based on the indication of the first indication information, one or more MCSs may be applied to multiple transmission opportunities within the CG cycle period. The following introduces the possible correspondence between multiple MCSs and multiple CG transmission opportunities within the CG cycle period when multiple MCSs are applied to the CG cycle period.

Scenario 1: Multiple CG transmission opportunities within the CG cycle period correspond one-to-one to multiple MCSs.

It can be understood that in this scenario, the number of CG transmission opportunities within the CG cycle period is the same as the number of MCSs applied to the CG cycle period.

Optionally, when it is determined that the number of MCSs applied to the CG cycle period is the same as the number of CG transmission opportunities within the CG cycle period, the terminal may further determine a plurality of CG transmission opportunities within the CG cycle period, corresponding one-to-one to the plurality of applied MCSs.

Optionally, in this scenario, the terminal can determine the MCS corresponding to each CG transmission opportunity based on the time domain order of multiple CG transmission opportunities in the CG cycle period and the size order of the indexes of multiple MCSs. For example, assuming that there are 3 CG transmission opportunities in the CG cycle period, and the terminal determines that among the multiple MCSs configured by the first configuration information, 3 MCSs with indices of 1, 4, and 5 are applied to the CG cycle period, then the terminal can determine that the MCS with an index of 1 corresponds to the first CG transmission opportunity in the CG cycle period, the MCS with an index of 4 corresponds to the second CG transmission opportunity in the CG cycle period, and the MCS with an index of 5 corresponds to the third CG transmission opportunity in the CG cycle period based on the index size order of these 3 MCSs.

Optionally, in this scenario, if the first indication information indicates the index of a group of MCSs applied to the CG cycle period, the terminal can determine the MCS corresponding to each CG transmission opportunity based on the time domain order of multiple CG transmission opportunities within the CG cycle period and the order of multiple MCSs in the group.

Exemplarily, it is assumed that the first configuration information configures multiple MCSs in a table format, and the table has 32 rows, which are respectively identified by indexes from 0 to 31. A possible format of the table is shown in Table 1:

Table 1

0 MCS index MCS index MCS index MCS index 1 MCS index MCS index MCS index … 31 MCS index

In Table 1, MCS index is the value of the MCS index. Multiple MCS indices corresponding to a row may be the same or different.

Assuming that the first indication information indicates index 0, the terminal determines, based on the first indication information, that the four MCSs corresponding to the row with index 0 in Table 1 are applied to the four CG transmission opportunities within the CG cycle period, and further determines that the MCS corresponding to the first column is the MCS corresponding to the first CG transmission opportunity within the CG cycle period, the MCS corresponding to the second column is the MCS corresponding to the second CG transmission opportunity within the CG cycle period, the MCS corresponding to the third column is the MCS corresponding to the third CG transmission opportunity within the CG cycle period, and the MCS corresponding to the fourth column is the MCS corresponding to the third CG transmission opportunity within the CG cycle period.

Assuming that the MCS index of the first column corresponding to the row with index 0 is 0, the MCS index of the second column is 1, the MCS index of the third column is 2, and the MCS index of the fourth column is 3, the terminal determines that the index of the MCS corresponding to the first CG transmission opportunity in the CG cycle period is 0, the index of the MCS corresponding to the second CG transmission opportunity in the CG cycle period is 1, the index of the MCS corresponding to the third CG transmission opportunity in the CG cycle period is 2, and the index of the MCS corresponding to the fourth CG transmission opportunity in the CG cycle period is 3.

Optionally, in this example, after the terminal determines the index of the MCS corresponding to the 4 CG transmission opportunities within the CG cycle period, the terminal can determine the MCS corresponding to the 4 CG transmission opportunities within the CG cycle period in combination with the pre-configured MCS indexed 0-31. Alternatively, the first configuration information itself can configure the modulation scheme and coding scheme respectively included in the MCS indexed 0-31, and configure the index of the MCS as shown in Table 1. After the terminal finds the index of the MCS corresponding to the 4 CG transmission opportunities within the CG cycle period in Table 1 according to the first indication information, it can determine the MCS corresponding to the 4 CG transmission opportunities within the CG cycle period in combination with the MCS configured by the first configuration information.

Scenario 2: At least two CG transmission opportunities within the CG cycle period correspond to the first common MCS among multiple MCSs.

Among them, public MCS is an exemplary name provided by the embodiment of the present application for the MCS shared by at least two CG transmission opportunities. It can also be called shared MCS, common MCS, etc. The embodiment of the present application does not limit the specific name.

It can be understood that in this scenario, the number of MCSs applied to the CG cycle period is less than the number of CG transmission opportunities within the CG cycle period.

Optionally, in scenario 2, within the CG cycle period, CG transmission opportunities other than the at least two CG transmission opportunities corresponding to the first public MCS mentioned above may correspond to MCSs other than the first public MCS in multiple MCSs, respectively. That is, except for the multiple CG transmission opportunities corresponding to the first public MCS, other CG transmission opportunities correspond one-to-one to MCSs other than the first public MCS in multiple MCSs. Among them, the number of CG transmission opportunities other than the at least two CG transmission opportunities corresponding to the first public MCS may be one or more.

Alternatively, in scenario 2, during the CG cycle period, in addition to the at least two CG transmission opportunities corresponding to the first common MCS, at least two CG transmission opportunities may correspond to the second common MCS among multiple MCSs. That is, among the multiple MCSs, there are at least two common MCSs corresponding to multiple CG transmission opportunities.

Optionally, in this scenario, the terminal can determine the MCS corresponding to each CG transmission opportunity within the CG cycle period based on a predefined mapping relationship.

The following is an introduction to the implementation of the MCS corresponding to each CG transmission opportunity within the CG cycle period by the terminal in scenario two, in combination with several exemplary mapping relationships provided in the embodiments of the present application.

In a possible implementation, if the number of MCSs applied to the CG cycle period (hereinafter referred to as M) is less than the number of CG transmission opportunities in the CG cycle period (hereinafter referred to as N), that is, M<N, and N is an integer multiple of M, the MCS corresponding to the CG transmission opportunity in the CG cycle period can satisfy the following relationship:

In the above mapping relationship, n represents the index/serial number of the CG transmission opportunity within the CG cycle period, that is, the nth CG transmission opportunity within the CG cycle period. X is used to indicate the index of the MCS corresponding to the nth CG transmission opportunity within the CG cycle period.

Exemplarily, it is assumed that the first configuration information configures multiple MCSs in a table format of 32 rows×8 columns (for details, please refer to Table 1). Then in the above mapping relationship, X represents the Xth column in the table.

Assuming that the CG cycle period includes 6 CG transmission opportunities, N = 6. The first indication information indicates that in the table configured by the first configuration information, the MCS corresponding to the row with index 1 is applied to the CG cycle period. According to the first indication information, the terminal determines that in the row with index 1, the first and second columns have corresponding MCS indexes, and the remaining columns have no corresponding MCS indexes, then M = 2. It can be understood that in this case, X is a maximum of 2.

According to the above mapping relationship, the terminal determines that when n=1, n=2, and n=3, n∈[1,N/M] is satisfied, corresponding to 1, and the index of the MCS corresponding to the first CG transmission opportunity, the second CG transmission opportunity, and the third CG transmission opportunity in the CG cycle period is determined to be the MSC index corresponding to the first column in the row with index 1. According to the above mapping relationship, the terminal determines that when n=4, n=5, and n=6, n∈[N/M+1,2*N/M] is satisfied, corresponding to 2, and the index of the MCS corresponding to the fourth CG transmission opportunity, the fifth CG transmission opportunity, and the sixth CG transmission opportunity in the CG cycle period is determined to be the MSC index corresponding to the second column in the row with index 1.

Assuming that the MSC index corresponding to the first column in a row with index 1 is 10, and the MSC index corresponding to the second column is 11, the terminal can determine that the MCS corresponding to the first CG transmission opportunity, the second CG transmission opportunity and the third CG transmission opportunity in the CG cycle period is the MCS with index 10, and the MCS corresponding to the fourth CG transmission opportunity, the fifth CG transmission opportunity and the sixth CG transmission opportunity in the CG cycle period is the MCS with index 11.

In another possible implementation, if M<N, and N cannot be divided by M, the MCS corresponding to each CG transmission opportunity in the CG cycle period can satisfy the following relationship:

Alternatively, the terminal can determine the MCS corresponding to each CG transmission opportunity within the CG cycle period based on the following mapping relationship.

In the above mapping relationship, n represents the index/serial number of the CG transmission opportunity within the CG cycle period, that is, the nth CG transmission opportunity within the CG cycle period. X is used to indicate the index of the MCS corresponding to the nth CG transmission opportunity within the CG cycle period. Indicates rounding up, for example Indicates rounding N/M upwards. Indicates rounding down, for example Indicates that N/M is rounded down.

Exemplarily, it is assumed that the first configuration information configures multiple MCSs in a table format of 32 rows×8 columns (for details, please refer to Table 1). Then in the above mapping relationship, X represents the Xth column in the table.

Assuming that the CG cycle period includes 7 CG transmission opportunities, N = 7. The first indication information indicates that in the table configured by the first configuration information, the MCS corresponding to the row with index 2 is applied to the CG cycle period. Based on the first indication information, the terminal determines that in the row with index 2, the first column, the second column, and the third column have corresponding MCS indexes, and the remaining columns have no corresponding MCS indexes, then M = 3. It can be understood that in this case, X is a maximum of 3.

If the terminal determines that n=1, n=2, and n=3 satisfy the condition according to the mapping relationship rounded up in the above mapping relationship, Corresponding to 1, the index of the MCS corresponding to the first CG transmission opportunity, the second CG transmission opportunity and the third CG transmission opportunity in the CG cycle period is the MSC index corresponding to the first column in the row with index 2. The terminal determines that n=4, n=5, and n=6 meet the following conditions based on the mapping relationship: Corresponding to 2, the index of the MCS corresponding to the 4th CG transmission opportunity, the 5th CG transmission opportunity and the 6th CG transmission opportunity in the CG cycle period is determined to be the MSC index corresponding to the second column in the row with index 1. The terminal determines that n=7 satisfies the mapping relationship. Corresponding to 3, the index of the MCS corresponding to the 7th CG transmission opportunity in the CG cycle period is determined as the MSC index corresponding to the third column in the row with index 1.

Assuming that the MSC index corresponding to the first column in a row with index 2 is 10, the MSC index corresponding to the second column is 11, and the MSC index corresponding to the third column is 12, the terminal can determine that the MCS corresponding to the first CG transmission opportunity, the second CG transmission opportunity and the third CG transmission opportunity in the CG cycle period is the MCS with index 10, and the MCS corresponding to the fourth CG transmission opportunity, the fifth CG transmission opportunity and the sixth CG transmission opportunity in the CG cycle period is the MCS with index 11. The MCS corresponding to the seventh CG transmission opportunity is the MCS with index 11.

The terminal determines the specific implementation of the MCS corresponding to the 7 CG transmission opportunities included in the CG cycle period according to the mapping relationship that is rounded down in the above mapping relationship. You can refer to the terminal's specific implementation of the MCS corresponding to the 7 CG transmission opportunities included in the CG cycle period according to the mapping relationship that is rounded up in the above mapping relationship, which will not be repeated here.

In another possible implementation, if the terminal determines that M<N, the terminal may correspond the first Y CG transmission opportunities within the CG cycle period to the same MCS, and the remaining N-Y CG transmission opportunities to other MCSs respectively.

Optionally, Y may be a fixed value predefined or indicated by a RAN node (e.g., configured by RRC signaling or indicated by DCI). Alternatively, Y may be a value of an expression predefined or indicated by a RAN node that is related to N or M. For example, Y may be equal to N-M+1, in which case the last M-1 CG transmission opportunities in the CG cycle period correspond to other MCSs respectively.

In this implementation, the MCS corresponding to the first Y CG transmission opportunities in the CG cycle period, and the MCS corresponding to the last N-Y CG transmission opportunities, can be determined by the terminal based on a preset mapping relationship.

Exemplarily, it is assumed that the first configuration information configures multiple MCSs in the form of a table of 32 rows × 8 columns (for details, please refer to Table 1). The first indication information indicates that in the table configured by the first configuration information, the MCS corresponding to the row with index 2 is applied to the CG cycle period. According to the first indication information, the terminal determines that in the row with index 2, the first column, the second column, and the third column have corresponding MCS indexes, and the remaining columns have no corresponding MCS indexes, then M=3.

Assuming that the CG cycle period includes 6 CG transmission opportunities, then N = 6. Assuming Y = N-M+1, the MCS corresponding to each CG transmission opportunity in the CG cycle period can satisfy the following relationship:

In the above mapping relationship, n represents the index/serial number of the CG transmission opportunity in the CG cycle period, that is, the nth CG transmission opportunity in the CG cycle period. X represents the Xth column in the table. It can be understood that, since M=3, in this case, X is a maximum of 3.

According to the above mapping relationship, the terminal determines that when n=1, n=2, n=3, and n=4, n∈[1,N-M+1] is satisfied, corresponding to 1. Then, the index of the MCS corresponding to the first 4 CG transmission opportunities in the CG cycle period is determined, which is the MSC index corresponding to the first column in the row with index 2.

According to the above mapping relationship, the terminal determines that when n=5, n=N-M+2 is satisfied, corresponding to 2, and then determines that the index of the MCS corresponding to the fifth CG transmission opportunity in the CG cycle period is the MSC index corresponding to the second column in the row with index 2. According to the mapping relationship, the terminal determines that when n=6, n=N is satisfied, corresponding to 3, and then determines that the index of the MCS corresponding to the sixth CG transmission opportunity in the CG cycle period is the MSC index corresponding to the third column in the row with index 1.

In another possible implementation, if the terminal determines that M=2 and M<N, the terminal may correspond the first N-Z CG transmission opportunities within the CG cycle period to the same MCS and the last Z CG transmission opportunities to another MCS.

Optionally, Z may be a fixed value predefined or indicated by the RAN node. For example, Z may be equal to 1.

Optionally, in this implementation, the index of the MCS corresponding to the first N-Z CG transmission opportunities, and/or the index of another MCS corresponding to the last Z CG transmission opportunities, may be predefined. Alternatively, it may be indicated to the terminal by the RAN node through the first indication information.

Exemplarily, the index of the MCS corresponding to the first N-Z CG transmission opportunities may be predefined as 1, and the index of the MCS corresponding to the last Z CG transmission opportunities may be predefined as 2. For another example, assuming that the first configuration information configures multiple MCSs in a table form (see Table 1 for details), the index of the MCS corresponding to the first N-Z CG transmission opportunities may be predefined as the MCS index corresponding to the first column in a row in the table indicated by the first indication information, and the index of the MCS corresponding to the last Z CG transmission opportunities may be the MCS index corresponding to the second column in a row in the table indicated by the first indication information.

The above introduces the specific implementation of the terminal determining the MCS corresponding to the CG transmission opportunity within the CG cycle period. It can be understood that in order to correctly receive the data transmitted by the terminal at the CG transmission opportunity, the RAN node can pre-agree with the terminal on the same scheme for determining the MCS corresponding to the CG transmission opportunity within the CG cycle period, and determine the MCS corresponding to the CG transmission opportunity within the CG cycle period according to the pre-agreement scheme.

In S402, for a CG transmission opportunity within the CG cycle period, the terminal can transmit data at the CG transmission opportunity according to the MCS corresponding to the CG transmission opportunity.

Among them, transmitting data according to the MCS corresponding to the CG transmission timing means transmitting data according to the modulation scheme and coding scheme defined by the MCS corresponding to the CG transmission timing.

Correspondingly, the RAN node receives data transmitted by the terminal at the CG transmission opportunity according to the MCS corresponding to the CG transmission opportunity. Receiving data according to the MCS corresponding to the CG transmission opportunity means receiving data according to a demodulation scheme and a decoding scheme corresponding to the modulation scheme and the coding scheme defined by the MCS.

Based on the communication method provided in the embodiment of the present application, the MCS can be configured through the first configuration information, and the configured MCS can be applied to multiple CG transmission opportunities within the CG cycle period indicated by the first indication information. Compared with the existing solution that multiple CG transmission opportunities within the CG cycle period can only correspond to the same pre-configured MCS, the first configuration information can configure one or more different MCSs according to actual needs. Therefore, this solution can improve the flexibility of configuring the MCS corresponding to multiple CG transmission opportunities within the CG cycle period.

The actions of the terminal or RAN node in the above steps S401 to S402 may be performed by the processor 301 shown in FIG. 3 calling the application code stored in the memory 303 to instruct the terminal or RAN node to execute.

The above mainly introduces the solution provided by the embodiment of the present application from the perspective of interaction between various network elements. Accordingly, the embodiment of the present application also provides a communication device, which is used to implement the above various methods.
