Description

Mobile communication uplink information scheduling method, terminal, network equipment and system

Technical Field

The present application relates to the field of mobile communications, and in particular, to a method, a device, and a system for scheduling uplink information in mobile communications.

Background

In a new generation wireless communication (NR) system, a Physical Uplink Shared Channel (PUSCH) may carry an uplink shared channel (UL-SCH) and/or Uplink Control Information (UCI) transmitted by a terminal device. The terminal equipment determines whether the sent physical uplink shared channel only comprises an uplink shared channel, only comprises aperiodic channel state information (A-CSI) or comprises both the uplink shared channel and the aperiodic channel state information according to uplink scheduling grant (UL grant) information sent by the network equipment on Downlink Control Information (DCI). If the terminal equipment needs to send information such as hybrid automatic repeat request (HARQ) acknowledgement messages, periodic channel state messages and the like in a Physical Uplink Control Channel (PUCCH) within the time for sending the physical uplink shared channel, and the physical uplink control channel and the physical uplink shared channel are not continuous in a frequency domain, the terminal equipment sends uplink control information which is sent in the physical uplink control channel to the base station through the physical uplink shared channel. And the terminal equipment determines whether the transmitted physical uplink shared channel comprises the aperiodic channel state information or not according to a channel state information request (CSI request) field in the uplink scheduling authorization.

The physical uplink shared channel sent by the terminal device may be divided into two types: the first type is that the physical uplink shared channel does not include the uplink shared channel, and only includes aperiodic channel state information and possibly other uplink control information corresponding to the physical uplink control channel; the second type is that the physical uplink shared channel includes an uplink shared channel. The uplink shared channel usually carries service data information from the terminal device to the network device. In order to ensure the transmission reliability of the service data information, the uplink shared channel transmission uses a hybrid automatic retransmission mechanism.

According to the prior art, the terminal device determines which of the two types of scheduled physical uplink shared channel is according to the 1-bit dedicated information in the uplink scheduling grant information. The terminal equipment also indexes (I) according to the modulation coding scheme in the uplink scheduling authorization_MCS) Determining the modulation order Q of the physical uplink shared channel_mAnd determining whether the transmitted physical uplink shared channel comprises aperiodic channel state information or not through channel state information request information in the uplink scheduling authorization.

Since the first type occurs less, the use of a 1-bit dedicated field in the uplink scheduling grant to distinguish the two types of physical uplink shared channels according to the prior art would bring about a load burden of the uplink scheduling grant, affecting the coverage of the network device and the transmission efficiency of the control information.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The scheme of the invention distinguishes different types of the physical uplink shared channel scheduled through the non-periodic channel state information, the modulation coding scheme and the specific state combination of the redundancy version in the uplink scheduling authorization sent by the network equipment, wherein the different types comprise that the physical uplink shared channel comprises the uplink shared channel, and the physical uplink shared channel does not comprise the uplink shared channel and only comprises uplink control information. When it is determined that the scheduled physical uplink shared channel does not include the uplink shared channel and only includes uplink control information through the combination of the aperiodic channel state information, the modulation coding scheme and the specific state of the redundancy version in the uplink scheduling grant, determining the modulation order of the physical uplink shared channel through the information of the hybrid automatic repeat request process number in the uplink scheduling; when the scheduled physical uplink shared channel comprises the uplink shared channel according to the non-periodic channel state information, the modulation coding scheme and the specific state combination of the redundancy version in the uplink scheduling authorization, the hybrid automatic repeat request process number of the uplink shared channel transmission block is determined according to the information of the hybrid automatic repeat request process number in the uplink scheduling.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 shows a first embodiment of the working flow of the terminal device according to the method of the present invention. An embodiment of the present application provides a method for scheduling uplink information of mobile communication, including the following steps:

step 101, a terminal device receives uplink scheduling authorization information, wherein the uplink scheduling authorization information comprises a channel state information request and also comprises a modulation coding scheme index value and/or a redundancy version index value;

step 102, the terminal device makes the following judgments: when the channel state information request indicates to send aperiodic channel state information, if the modulation coding scheme index value is a first predetermined value and/or the redundancy version index value is a second predetermined value, the terminal device does not include an uplink shared channel in the sent physical uplink shared channel.

In this step, the terminal device sends the physical uplink shared channel according to the uplink scheduling grant information sent by the network device. For example, the uplink scheduling grant information includes time-frequency resources of the physical uplink shared channel, a timing relationship between the scheduling grant information and the physical uplink shared channel, a modulation coding scheme used by the physical uplink shared channel, a coding redundancy version of the physical uplink shared channel, a precoding matrix, and other information. The terminal equipment can determine the resource, form, content and the like of the physical uplink shared channel according to the scheduling authorization.

It should be noted that when the physical uplink shared channel scheduled by the uplink scheduling grant does not include the uplink shared channel, the physical uplink shared channel must include aperiodic channel state information. Otherwise, on the premise that there is no uplink shared channel transmission block and there is no transmission of aperiodic channel state information, the network device does not need to schedule the terminal device to send the physical uplink shared channel through the scheduling grant. In this embodiment, the first field includes a "channel state information request" for indicating whether aperiodic channel state information is triggered and a set of triggered aperiodic channel state information if the terminal device is triggered to transmit the aperiodic channel state information.

It should be noted that, throughout the present document, a combination of the csi request indication, the mcs index value, and/or the redundancy version index value is referred to as a first field, and the first field includes one of the following cases:

channel state information request indication, modulation coding scheme index value;

channel state information request indication, redundancy version index value;

a channel state information request indication, a modulation coding scheme index value, a redundancy version index value.

The method comprises the steps that a physical uplink shared channel sent by terminal equipment is subjected to rate matching in a coding process to generate 4 redundancy versions, and the generation modes of the 4 redundancy versions are determined by RV 0, RV 1, RV 2 and RV 3 respectively. The redundancy version index field in the scheduling grant is used to determine which redundancy version the terminal device determines to use for the transmitted uplink shared channel. The modulation coding scheme index is used to determine a modulation order (Q)_m) And a target coding rate (R).

The first state is called as a first state, and the first state includes three situations:

the first case: the channel state information request indicates that the aperiodic channel state information is sent and the index value of the modulation coding scheme is a first preset value;

the second case: the channel state information request indicates that the non-periodic channel state information and the redundancy version index value are sent as a second preset value;

the third situation: the channel state information request indicates that aperiodic channel state information is transmitted, the modulation and coding scheme index value is a first predetermined value, and the redundancy version index value is a second predetermined value.

Of the states represented by the first field, the states other than the first state are referred to as second states. According to the scheme of the invention, the terminal equipment determines the scheduled physical uplink shared channel to be of one of two types according to the state indicated by the first field in the uplink scheduling authorization: when the first field indicates the first state, the physical uplink shared channel scheduled by the scheduling grant is of the first type, that is, the physical uplink shared channel does not include the uplink shared channel, and only includes aperiodic channel state information and possibly some other uplink control information corresponding to the physical uplink control channel; when the first field indicates the second state, the physical uplink shared channel scheduled by the scheduling grant is of the second type, i.e. the physical uplink shared channel includes an uplink shared channel. For the second type, the physical uplink shared channel may further include aperiodic channel state information and/or other uplink control information corresponding to the physical uplink control channel, or may not include the uplink control information.

In order to avoid using a special field in the uplink scheduling authorization, the invention distinguishes two types of the scheduled PUSCH through the first state and the second state of the first field in the uplink scheduling authorization, and the scheduling flexibility when the PUSCH transmits the UL-SCH is influenced. That is, the network device cannot use the scheduling for the second type of PUSCH corresponding to the first state of the first field. However, if the second type of PUSCH scheduling is less likely to use the situation corresponding to the first state of the first field, the impact on scheduling flexibility of the PUSCH is small. Compared with the prior art that the special field is used in the uplink scheduling authorization, the scheme of the invention can avoid the load burden of the uplink scheduling authorization and improve the coverage of the network equipment and the transmission efficiency of the control information.

In this embodiment, if the first field includes a channel state information request indication and a modulation and coding scheme index value, when the first field indicates the first state, that is, the channel state information request indication indicates to transmit aperiodic channel state information and the modulation and coding scheme index value is a first predetermined value, the terminal device does not include an uplink shared channel in the transmitted physical uplink shared channel. If the first segment indicates that the physical uplink shared channel is not in the first state, the terminal device includes the uplink shared channel in the transmitted physical uplink shared channel, that is, the transport block size of the uplink shared channel is greater than zero. Compared with the prior art that a dedicated field is used in the uplink scheduling grant, the scheme of this embodiment is used, as long as the network device does not use the modulation and coding scheme corresponding to the first predetermined value when the scheduling terminal device sends the physical uplink shared channel and the physical uplink shared channel includes the uplink shared channel and the aperiodic channel state information. For example, the csi request indicates that aperiodic csi is transmitted, and the mcs index is a first predetermined value (e.g. 31), which is the first state, and the ue does not include the physical uplink shared channel in the transmitted physical uplink shared channel. In contrast, when the channel state information request indicates that the aperiodic channel state information is not transmitted or the modulation and coding scheme index value is not the first predetermined value (for example, 31), the state is the second state, and at this time, the terminal device includes the uplink shared channel in the transmitted physical uplink shared channel. That is, if the first field includes a channel state information request indication and a modulation and coding scheme index value, when the modulation and coding scheme index value is not the first predetermined value or when the channel state information request indication does not send aperiodic channel state information, the terminal device includes an uplink shared channel in a sent physical uplink shared channel. If the terminal equipment contains the uplink shared channel in the transmitted physical uplink shared channel, the terminal equipment determines whether the non-periodic channel state information is included outside the uplink shared channel in the physical uplink shared channel according to the channel state information request indication in the first field, and determines the modulation and coding scheme used for transmitting the uplink shared channel according to the modulation and coding scheme index value in the first field.

In this embodiment, if the first field includes a channel state information request indication and a redundancy version index value, when the first field indicates the first state, that is, the channel state information request indication indicates to send aperiodic channel state information and the redundancy version index value is a second predetermined value, the terminal device does not include an uplink shared channel in the sent physical uplink shared channel. If the indication of the first segment is not the first state, the terminal device includes the uplink shared channel in the transmitted physical uplink shared channel, that is, the transport block size of the uplink shared channel is greater than zero. Compared with the prior art that a dedicated field is used in the uplink scheduling grant, the scheme of this embodiment is used, as long as the network device does not use the redundancy version corresponding to the second predetermined value when the scheduling terminal device sends the physical uplink shared channel and the physical uplink shared channel includes the uplink shared channel and the aperiodic channel state information. The scheme of the embodiment has small influence on the scheduling flexibility of the PUSCH, avoids the load burden of uplink scheduling authorization, and can improve the coverage of network equipment and the transmission efficiency of control information. For example, the channel state information request indicates that aperiodic channel state information is transmitted, and when the redundancy version index value is a second predetermined value (e.g., 1), the state is the first state, and at this time, the terminal device does not include the uplink shared channel in the transmitted physical uplink shared channel. In contrast, when the channel state information request indicates that the aperiodic channel state information is not transmitted or the redundancy version index value is not a second predetermined value (e.g., 1), the state is the second state, and in this case, the terminal device includes the uplink shared channel in the transmitted physical uplink shared channel. That is, if the first field includes a channel state information request indication and a redundancy version index value, when the redundancy version index value is not the second predetermined value or when the channel state information request indication does not send aperiodic channel state information, the terminal device includes an uplink shared channel in the sent physical uplink shared channel. If the terminal equipment contains the uplink shared channel in the transmitted physical uplink shared channel, the terminal equipment determines whether the non-periodic channel state information is included outside the uplink shared channel in the physical uplink shared channel according to the channel state information request indication in the first field, and determines the modulation and coding scheme used for transmitting the uplink shared channel according to the modulation and coding scheme in the first field. If the terminal equipment contains the uplink shared channel in the transmitted physical uplink shared channel, the terminal equipment determines whether the non-periodic channel state information is included outside the uplink shared channel in the physical uplink shared channel according to the channel state information request indication in the first field, and determines the redundancy version used for transmitting the uplink shared channel according to the redundancy version index value in the first field.

In the present embodiment, if the first field includes a channel state information request indication, a modulation coding scheme index value, and a redundancy version index value. When the first field indicates the first state, that is, the channel state information request indicates that aperiodic channel state information is transmitted, the modulation and coding scheme index value is the first predetermined value, and the redundancy version index value is the second predetermined value, the terminal device does not include the uplink shared channel in the transmitted physical uplink shared channel. If the indication of the first segment is not the first state, the terminal device includes the uplink shared channel in the transmitted physical uplink shared channel, that is, the transport block size of the uplink shared channel is greater than zero. Compared with the prior art that a dedicated field is used in the uplink scheduling grant, the scheme of this embodiment is used, as long as the network device does not use the modulation and coding scheme corresponding to the first predetermined value and the redundancy version corresponding to the second predetermined value at the same time when the scheduling terminal device sends the physical uplink shared channel, and the physical uplink shared channel includes the uplink shared channel and includes the aperiodic channel state information. The scheme of the embodiment has small influence on the scheduling flexibility of the PUSCH, avoids the load burden of uplink scheduling authorization, and can improve the coverage of network equipment and the transmission efficiency of control information. For example, the csi request indicates that aperiodic csi is transmitted, and when the mcs index is a first predetermined value (e.g., a fixed value 29, or any integer value from 28 to 31) and the redundancy version index is a second predetermined value (e.g., 1), the csi is in the first state, and at this time, the ue does not include an uplink shared channel in the transmitted physical uplink shared channel. In contrast, the channel state information request indicates that the aperiodic channel state information is not transmitted, or the modulation and coding scheme index value is not a first predetermined value (for example, a fixed value 29, or any integer value from 28 to 31), or the redundancy version index value is not a second predetermined value (for example, 1), and in this case, the terminal device includes the uplink shared channel in the transmitted physical uplink shared channel. That is, if the first field includes a channel state information request indication, a modulation and coding scheme index value and a redundancy version index value, when at least one of that the modulation and coding scheme index value is not the first predetermined value and that the redundancy version index value is not the second predetermined value and that the channel state information request indication does not send aperiodic channel state information is satisfied, the terminal device includes an uplink shared channel in a sent physical uplink shared channel. If the terminal equipment contains the uplink shared channel in the transmitted physical uplink shared channel, the terminal equipment determines whether the non-periodic channel state information is included outside the uplink shared channel in the physical uplink shared channel according to the channel state information request indication in the first field, determines a modulation coding scheme used for transmitting the uplink shared channel according to a modulation coding scheme index value in the first field, and determines a redundancy version used for transmitting the uplink shared channel according to a redundancy version index value in the first field.

In the present embodiment, the first field includes a redundancy version index (RV ID), a modulation coding scheme index (I) in addition to channel state information request (CSI request) information_MCS) At least one of (1).

Fig. 2 shows a second embodiment of the working flow of the terminal device in the method of the present invention. An embodiment of the present application further provides a method for scheduling uplink information of mobile communication, including the following steps:

step 201, a terminal device receives uplink scheduling authorization information, wherein the uplink scheduling authorization information contains an index value of a hybrid automatic repeat request process;

it should be noted that the scheduling grant information includes a second field, and in this embodiment, the second field is a hybrid automatic repeat request process index (HARQ process number) value in the scheduling grant;

further, the uplink scheduling grant information includes the first field, that is, the channel state information request, the modulation and coding scheme index value, and the redundancy version index value;

a hybrid automatic repeat request process refers to a process of performing data transmission once and then receiving HARQ-ACK information corresponding to the process data. N concurrent hybrid automatic repeat request processes may be used in a wireless communication system. Wherein N is an integer of 1 or more. Respective hybrid automatic repeat request processes are identified for both communicating parties. And respectively numbering and indexing N hybrid automatic repeat processes which are transmitted in parallel, and identifying the information of the index value of the scheduled hybrid automatic repeat process and the index value information of the hybrid automatic repeat process in uplink scheduling authorization.

Step 202, the terminal device makes the following judgments: when the terminal device does not include the uplink shared channel in the transmitted physical uplink shared channel, the terminal device uses the hybrid automatic repeat request process index value to identify at least one of a modulation order, a target coding rate and a spectral efficiency of the physical uplink shared channel.

As an embodiment of further optimization in step 202, the uplink scheduling grant information includes a first field. If the first field is in a first state, then: when the channel state information request indicates to send aperiodic channel state information, if the modulation coding scheme index value is a first predetermined value and/or the redundancy version index value is a second predetermined value, the terminal device identifies at least one of a modulation order, a target coding rate and spectral efficiency of the physical uplink shared channel by using a hybrid automatic repeat request process index value. It should be noted that, if the first field is in the second state, the terminal device determines, according to the second field, a hybrid automatic repeat request process number corresponding to the transport block of the uplink shared channel.

When the physical uplink shared channel scheduled by the uplink scheduling grant is of the first type, the physical uplink shared channel has no transmission block of the uplink shared channel, and the hybrid automatic repeat request process index in the uplink scheduling grant is idle. I.e. the terminal device does not need to use the hybrid automatic repeat request process index. In this case, in the present embodiment, the hybrid automatic repeat request process index may be used to indicate a modulation order of the first type physical uplink shared channel. For example, the harq process index includes 4 bits, and the modulation order of the first type of physical uplink shared channel includes at least one of the 4 types: QPSK, 16QAM, 64QAM and 256 QAM. The terminal device may use the top 2 bits of the hybrid automatic repeat request process index to indicate the modulation order of the first type physical uplink shared channel. For example, "00" indicates that the modulation order of the first type physical uplink shared channel is 2, i.e. QPSK, "01" indicates that the modulation order of the first type physical uplink shared channel is 4, i.e. 16QAM, "10" indicates that the modulation scheme order of the first type physical uplink shared channel is 6, i.e. 64QAM, and "11" indicates that the modulation order of the first type physical uplink shared channel is 8, i.e. 256 QAM. Or the lowest 2 bits of the hybrid automatic repeat request process index are used for representing the modulation order of the first type physical uplink shared channel. In this embodiment, a specific implementation manner of the second field indicating the modulation order of the first type physical uplink shared channel is not limited. Some or all of the information bits of the second field may be used to indicate a modulation order of the first type physical uplink shared channel.

Or, when the physical uplink shared channel scheduled by the uplink scheduling grant is of the first type, there is no transport block of the uplink shared channel in the physical uplink shared channel, and only the uplink control information including the aperiodic channel state information is included in the physical uplink shared channel, the harq process index may be used to indicate at least one of a modulation order, a coding rate, and a spectrum efficiency of the physical uplink shared channel of the first type. In this case, the network device and the terminal device are preset with a correspondence between the harq process index and at least one of a modulation order, a coding rate, and a spectrum efficiency. And the terminal equipment determines at least one of the modulation order, the coding rate and the spectral efficiency of the first type physical uplink shared channel according to the hybrid automatic retransmission process index and the preset corresponding relation. In this embodiment, a specific implementation manner that the second field indicates at least one of a modulation order, a coding rate, and a spectrum efficiency of the first type physical uplink shared channel is not limited. Some or all information bits of the second field may be used to indicate at least one of a modulation order, a coding rate, and a spectral efficiency of the first type physical uplink shared channel.

In this embodiment, when the physical uplink shared channel sent by the terminal device does not include the uplink shared channel, the harq process index in the uplink scheduling grant is used to instruct the terminal device to send at least one of the modulation order, the coding rate, and the spectral efficiency of the uplink shared channel, and when the physical uplink shared channel sent by the terminal device includes the uplink shared channel, the harq process index in the uplink scheduling grant is used to instruct the terminal device to send the harq process number of the transport block corresponding to the uplink shared channel, which may improve the transmission efficiency of the control information of the network device.

it should be noted that the uplink scheduling grant information includes a second field, and in this embodiment, the second field is a hybrid automatic repeat request process index value in the uplink scheduling grant.

Step 302, the terminal device makes the following judgments: when the channel state information request indicates to send aperiodic channel state information, if the modulation coding scheme index value is a first predetermined value and/or the redundancy version index value is a second predetermined value, the terminal device does not include an uplink shared channel in the sent physical uplink shared channel;

step 303, the terminal device makes the following judgments: when the terminal device does not include the uplink shared channel in the transmitted physical uplink shared channel, the terminal device uses the hybrid automatic repeat request process index value to identify at least one of a modulation order, a target coding rate and a spectrum efficiency of the physical uplink shared channel.

It should be further noted that, if the terminal device determines that the transmitted physical uplink shared channel includes the uplink shared channel according to the state of the first field, the terminal device determines whether non-periodic channel state information is included outside the uplink shared channel in the physical uplink shared channel according to the channel state information request indication in the first field, determines a modulation and coding scheme used for transmitting the uplink shared channel according to the modulation and coding scheme index value in the first field, and determines a redundancy version used for transmitting the uplink shared channel according to the redundancy version index value in the first field. And the terminal equipment determines a hybrid automatic repeat request process number corresponding to the transmission block of the uplink shared channel according to the second field.

The embodiment has less influence on the scheduling flexibility of the physical uplink shared channel, and avoids the load burden of uplink scheduling authorization to distinguish whether the sent physical uplink shared channel comprises the uplink shared channel, so that the coverage of the network equipment and the transmission efficiency of the control information can be improved. And, when the physical uplink shared channel sent by the terminal device does not include the uplink shared channel, the hybrid automatic repeat request process index in the uplink scheduling grant is used to instruct the terminal device to send at least one of the modulation order, the coding rate and the spectrum efficiency of the uplink shared channel, and when the physical uplink shared channel sent by the terminal device includes the uplink shared channel, the hybrid automatic repeat request process index in the uplink scheduling grant is used to instruct the terminal device to send the hybrid automatic repeat request process number of the transport block corresponding to the uplink shared channel, so that the transmission efficiency of the control information of the network device can be improved.

Fig. 4 shows a first embodiment of the network device workflow of the method of the present invention. An embodiment of the present application further provides a method for scheduling uplink information of mobile communication, including the following steps:

step 401, a network device sends uplink scheduling authorization information, where the uplink scheduling authorization information includes a channel state information request, and also includes a modulation and coding scheme index value and/or a redundancy version index value;

Step 402, the network device makes the following judgments: when the channel state information request indicates sending aperiodic channel state information, if the modulation coding scheme index value is a first predetermined value and/or the redundancy version index value is a second predetermined value, the network device does not include an uplink shared channel in the received physical uplink shared channel.

The first state corresponding to the first field includes three cases, specifically, for example:

the first situation is that: the channel state information request indicates that the aperiodic channel state information is sent and the index value of the modulation coding scheme is a first preset value;

the second case: the channel state information request indicates that the non-periodic channel state information and the redundancy version index value are sent to be a second preset value;

Of the states represented by the first field, the states other than the first state are referred to as second states.

The first situation is that: the channel state information request indicates that aperiodic channel state information is transmitted, and the modulation and coding scheme index value is a first predetermined value (e.g. 31), which is the first state, at this time, the network device does not include the uplink shared channel in the received physical uplink shared channel. In contrast, when the channel state information request indicates that the aperiodic channel state information is not transmitted or the modulation and coding scheme index value is not the first predetermined value (e.g. 31), the state is the second state, and in this case, the network device includes the uplink shared channel in the received physical uplink shared channel.

The second situation is that: the channel state information request indicates that aperiodic channel state information is sent, and when the redundancy version index value is a second predetermined value (for example, 1), the state is the first state, and at this time, the network device does not include the uplink shared channel in the received physical uplink shared channel. On the contrary, when the csi request indicates not to transmit the aperiodic csi or the redundancy version index value is not the second predetermined value (for example, 1), the csi is in the second state, and at this time, the network device includes the uplink shared channel in the received physical uplink shared channel.

The second situation is that: the csi request indicates to send aperiodic csi, and when the modulation and coding scheme index is a first predetermined value (e.g., a fixed value 29, or any integer value from 28 to 31) and the redundancy version index is a second predetermined value (e.g., 1), the csi is in a first state, and at this time, the network device does not include an uplink shared channel in the received physical uplink shared channel. On the contrary, the channel state information request indicates that the aperiodic channel state information is not transmitted, or the modulation and coding scheme index value is not a first predetermined value (for example, a fixed value 29, or any integer value from 28 to 31), or the redundancy version index value is not a second predetermined value (for example, 1), and in this case, the network device includes the uplink shared channel in the received physical uplink shared channel.

As an embodiment of further optimization in step 502, the uplink scheduling grant information includes a first field. If the first field is in the first state, then: when the channel state information request indicates to send aperiodic channel state information, if the modulation coding scheme index value is a first predetermined value and/or the redundancy version index value is a second predetermined value, the network device identifies at least one of a modulation order, a target coding rate and a spectral efficiency of the physical uplink shared channel by using a hybrid automatic repeat request process index value.

It should be noted that, if the first field is in the second state, the network device uses the second field to identify a harq process number corresponding to the transport block of the uplink shared channel.

Step 502 in this embodiment corresponds to step 202 in the first embodiment, where when the physical uplink shared channel sent by the terminal device does not include the uplink shared channel, the hybrid automatic repeat request process index in the uplink scheduling grant is used to instruct the terminal device to send at least one of the modulation order, the coding rate, and the spectrum efficiency of the uplink shared channel, and when the physical uplink shared channel sent by the terminal device includes the uplink shared channel, the hybrid automatic repeat request process index in the uplink scheduling grant is used to instruct the terminal device to send the hybrid automatic repeat request field number of the transport block corresponding to the uplink shared channel, which may improve the transmission efficiency of the control information of the network device.

The PUSCH sent by the terminal equipment generates 4 redundancies by rate matching in the coding process, the RVID0/3 can carry out self-decoding, and the performance of RVID 2 is better than that of RVID1, so the probability of selecting to use RVID1 is lower.

In Table 1, if 0. ltoreq.I_MCSLess than or equal to 28, the terminal equipment is according to I_MCSThe indication of (2) determines a modulation and coding scheme used for transmitting the physical uplink shared channel. And determining the size of the uplink shared channel transmission block according to the resource allocation information in the uplink scheduling grant. If 29. ltoreq.I_MCSIf the size of the uplink shared channel transmission block sent by the terminal equipment is less than or equal to 31, the transmission block is scheduled for the last time, and I is more than or equal to 0_MCSAnd determining the uplink scheduling grant less than or equal to 28. I is more than or equal to 0_MCSLess than or equal to 28For initial transmission or retransmission of uplink shared channel transmission block, but I is more than or equal to 29_MCS≦ 31 is typically used for retransmission of the uplink shared channel transport block.

Also, in tables 2 and 3, 0. ltoreq.I_MCSLess than or equal to 27 is used for initial transmission or retransmission of the uplink shared channel transmission block, and I is more than or equal to 28_MCS≦ 31 is typically used for retransmission of the uplink shared channel transport block.

To avoid using a dedicated field in the uplink scheduling grant,

in the method, apparatus or system according to any of the embodiments of the present invention, the first predetermined value is any integer value from 28 to 31. Specifically, when the physical uplink shared channel is the transmission block modulation coding mode I of the uplink shared channel _MCSThe first predetermined value is any one of integer values 29 to 31 as determined using table 1; modulation coding mode I of transmission block of uplink shared channel in physical uplink shared channel_MCSThe first predetermined value is any one of integer values 28 to 31 as determined using table 2 or table 3.

For example, the first preset value is any one integer value from 28 to 31. If the terminal device or the network device determines that the physical uplink shared channel does not contain the uplink shared channel according to the fact that the modulation coding scheme index value in the uplink scheduling grant is the first preset value and the channel state information request indication sends the aperiodic channel state information; the modulation coding scheme index value and other states indicated by the channel state information request determine that the physical uplink shared channel includes the uplink shared channel, and when the physical uplink shared channel includes the uplink shared channel and the physical uplink shared channel includes the aperiodic channel state information, the modulation coding scheme corresponding to the first predetermined value is not used in the retransmission process of the transmission block of the uplink shared channel. In these cases, the probability that the modulation and coding scheme needs to use any integer value from 28 to 31 is very small, so the scheme has a small impact on the scheduling flexibility of the uplink shared channel, and avoids the load burden of uplink scheduling grant to distinguish whether the sent physical uplink shared channel includes the uplink shared channel, which can improve the coverage of the network device and the transmission efficiency of the control information.

In the method, apparatus or system according to any one of the embodiments of the present invention, the first predetermined value is an integer value, for example, 29, which is greater than or equal to 28 and smaller than or equal to 31. If the terminal equipment or the network equipment determines that the physical uplink shared channel does not contain the uplink shared channel according to the condition that the modulation coding scheme index value in the uplink scheduling authorization is a first preset value and the channel state information request indication sends the aperiodic channel state information; the modulation coding scheme index value and other states indicated by the channel state information request determine that the physical uplink shared channel includes the uplink shared channel, and when the physical uplink shared channel includes the uplink shared channel and the physical uplink shared channel includes the aperiodic channel state information, the modulation coding scheme corresponding to the first predetermined value is not used in the retransmission process of the transmission block of the uplink shared channel. The probability that the modulation coding scheme needs to use any one of the integer values of 29 in these cases is small. Any integer value from 28 to 31 compared to said first predetermined value. The first preset value of 29 is used for causing less influence on the scheduling flexibility of the physical uplink shared channel, and the load burden of uplink scheduling authorization is avoided for distinguishing whether the sent physical uplink shared channel comprises the uplink shared channel, so that the coverage of the network equipment and the transmission efficiency of the control information can be improved. Specifically, the first predetermined value is equal to 28, 29, 30, or 31.

Preferably, in the method, apparatus or system according to any embodiment of the present invention, the first predetermined value is equal to 31.

Modulation coding mode I of transmission block of uplink shared channel in physical uplink shared channel_MCSWhen tables 1 and 3 are used for determination, the modulation order corresponding to the first predetermined value of 31 is 6, namely 64 QAM; modulation coding mode I of transmission block of uplink shared channel in physical uplink shared channel_MCSAs determined using table 2, a modulation order of 8, i.e., 256QAM, corresponds to a first predetermined value of 31. Considering the physical uplink shared channel as an uplink shared channel, and the retransmission uses high-order modulation, such as 64QAM, 2The probability of 56QAM is low, the scheme has little influence on the scheduling flexibility of the physical uplink shared channel, and avoids the load burden of uplink scheduling authorization to distinguish whether the sent physical uplink shared channel comprises the uplink shared channel, thereby improving the coverage of network equipment and the transmission efficiency of control information.
