Currently, the standard protocol-related discussion of NR systems is as follows:

Agreements:

·Support configurable size for“PDSCH-to-HARQ_feedback timing indicator(0or 1or 2or 3bits)”for the new DCI format for DL scheduling。

·New RRC parameter is introduced to for the configuration。

Agreements:

·Support configurable size for“beta offset indicator(0or 1or 2bits)”for the new DCI format for UL scheduling。

·New RRC parameter is introduced to for the configuration。

in the existing elementary, it is determined that the bit number of a field with a part of indication fields can be configured to be 0bit, which causes configuration information loss, and causes system efficiency reduction or incapability of working. Different bit numbers can be configured for the bit number of part of the indication fields, the different bit numbers correspond to different values, and how to take the values is not specified.

Based on the above technical background, embodiments of the present application provide a parameter determining method, which is described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a schematic flow chart of a parameter determining method according to an embodiment of the present application, and as shown in the figure, the method includes:

step 201, a network device sends first configuration information to a terminal device, where the first configuration information is used for the terminal device to determine a bit number of a first information field of a first downlink control information format DCI format, and the bit number of the first information field is associated with a first set, where the first set includes at least one piece of optional information; the bit number of the first information field is used for the terminal equipment to determine the first information indicated by the first information field.

Wherein the first DCI format may be a new DCI format. For example DCI format 0_ 2.

The first information is information in the first set, the information is also called an element, and the naming is not limited uniquely.

The first configuration information may be configured through a high-layer signaling, such as a Radio Resource Control (RRC) signaling.

The terminal equipment determines first information indicated by the first information domain, wherein the preset information only comprises the bit number of the first information domain; or, the preset information includes the bit number of the first information field and at least one of the following: a value of the first information field, the first set.

Step 202, a terminal device receives first configuration information, where the first configuration information is used by the terminal device to determine a bit number of a first information field of a first DCI format, and the bit number of the first information field is associated with a first set, where the first set includes at least one piece of optional information;

step 203, the terminal device determines the first information indicated by the first information field according to the bit number of the first information field.

In a specific implementation, the determining, by the terminal device, first information indicated by the first information field according to the bit number of the first information field includes: the terminal equipment determines first information indicated by the first information domain according to preset information, wherein the preset information only comprises the bit number of the first information domain; or, the preset information includes the bit number of the first information field and at least one of the following: a value of the first information field, the first set.

In one possible example, the first configuration information includes information for configuring the first set, the method further comprising: and the terminal equipment determines the bit number of the first information domain according to the information for configuring the first set. Correspondingly, the first configuration information includes information for configuring the first set, and the information for configuring the first set is used by the terminal device to determine the bit number of the first information field.

Wherein the first set is used for implicitly configuring the bit number of the first information field. In particular, the agreement may agree on a correspondence between the number of elements of the first set and the number of bits of the first information field.

For example, if there are 1 or 2 elements in the first set, the number of bits of the first information field is 1bit, if there are 3 or 4 elements in the set, the number of bits of the first information field is 2bit, and so on.

As can be seen, in this example, the bit number of the first information field is implicitly configured by the first set, and no additional information is required for indication, so that data redundancy is reduced, and system efficiency is improved.

In one possible example, the first configuration information includes information indicating a number of bits of the first information field.

The information of the bit number of the first information field may be implemented by configuring 1 or more bit bits, the specific bit number may be determined according to the type of the bit number supported by the first information field, for example, if the first information field supports 0/1/2/3 four configurations, the bit number may be indicated by 2 bits, where 00 indicates that the bit number of the first information field is 0, 01 indicates that the bit number of the first information field is 1, 10 indicates that the bit number of the first information field is 2, and 11 indicates that the bit number of the first information field is 3.

The information of the bit number of the first information field may also be configured by a method directly indicating, such as directly indicating an integer, for example 0/1/2/3.

As can be seen, in this example, the first configuration information may include information directly indicating the number of bits of the first information field, which is concise and efficient.

In one possible example, the first information field is a PDSCH-to-HARQ _ feedback timing indicator field for a hybrid automatic repeat request feedback of a physical downlink shared channel.

In this possible example, the bit number of the feedback delay indication field of the harq feedback is 0.

In this possible example, the first information is a preset feedback delay agreed by the protocol.

The preset feedback delay may be pre-stored at the terminal device side (for example, the network side indicates configuration, or the protocol convention), and is triggered to be used when the bit number of the first information field is 0.

The preset feedback delay may be information of dedicated configuration other than the first set, and is not limited herein.

In this example, the preset information specifically includes only the bit number of the first information field.

It can be seen that, in this example, when the bit number of the feedback delay indication field of the harq is 0, the preset feedback delay may be triggered to be used, so as to ensure system stability.

In this possible example, the first information is a feedback delay agreed by the protocols in the first set.

Wherein the first set may be configured by higher layer signaling.

The feedback delay agreed by the protocols in the first set may be specifically a first element in the first set.

In this example, the preset information specifically includes the number of bits in the first information field and the first set.

As can be seen, in this example, when the bit number of the feedback delay indication field of the harq is 0, the specific feedback delay in the first set may be triggered to be used, so as to ensure system stability.

In one possible example, the number of bits in the feedback delay indicator field of the pdcch hybrid automatic repeat request is an integer greater than 0.

When the bit number of the feedback delay indication field of the pdcch hybrid automatic repeat request is greater than 0, the bit number may be 1/2/3 bits.

In this possible example, the first information is feedback delay in the first set indicated by the pdcch harq feedback delay indication field.

Wherein the first set is a feedback delay set. The elements in the feedback delay set may be arranged in a preset order, such as from small to large or from large to small.

The first elements of the feedback delay set can be configured to be shorter feedback delay, and when the bit number configuration of the physical downlink shared channel hybrid automatic repeat request feedback delay indication domain is less, the elements in the front of the feedback delay set can be selected.

In this example, the preset information specifically includes a bit number of a first information field, a value of the first information field, and the first set.

As can be seen, in this example, when the bit number of the PDSCH-to-HARQ _ feedback timing indicator field is greater than 0, the first information may be determined by the indication information of the HARQ feedback delay indication field and the first set.

In one possible example, the first set configures an indicated set for a first set of feedback delays of a plurality of feedback delay set configurations;

the multiple feedback delay set configurations correspond to multiple DCI formats, and each feedback delay set configuration corresponds to each DCI format one-to-one, where the multiple DCI formats include the first DCI format.

The DCI formats include DCI format _1, DCI format _2, new DCI format, and the like, which are not limited herein.

In specific implementation, the number of bits in the feedback delay indication field of the hybrid automatic repeat request of different physical downlink shared channels is different from the number of elements in the corresponding set.

If the bit number of the feedback delay indication field of the hybrid automatic repeat request of the physical downlink shared channel is 1bit, the feedback delay set may have no more than 2 elements.

If the bit number of the feedback delay indication field of the hybrid automatic repeat request of the physical downlink shared channel is 2 bits, the feedback delay set may have no more than 4 elements.

If the bit number of the feedback delay indication field of the physical downlink shared channel hybrid automatic repeat request is 3 bits, the feedback delay set may have no more than 8 elements.

For example, a smaller feedback delay is configured for Ultra-high Reliable and Ultra-low latency Communication (URLLC), so that Hybrid Automatic Repeat Request (HARQ) feedback corresponding to a Physical Downlink Shared Channel (PDSCH) can be transmitted as soon as possible, a requirement of a short delay is ensured, and a transmission rate is ensured by configuring a mass Machine Type Communication (eMBB).

In addition, when the DCI format _1 is not configured with the feedback delay set, the DCI format _2 is configured with the feedback delay set independently, and does not depend on the feedback delay set of the DCI format _1, thereby improving system stability.

In this example, the preset information specifically includes a bit number of the first information field, a value of the first information field, and the first set.

As can be seen, in this example, a feedback delay set is configured for the DCI format independently, so that different service adjustment transmission strategies can be adapted, service requirements are met, and a transmission rate is guaranteed.

In one possible example, the first set is a set indicated by a (single) feedback delay set configuration, the first set corresponds to a plurality of DCI formats, the plurality of DCI formats includes the first DCI format;

the bit number of the first information field is n, the first information field corresponds to the first 2^ n information in the first set, the ordering of the optional information in the first set is a preset sequence, and n is a positive integer.

The preset sequence is from small to large or from large to small, and is not limited uniquely here.

The value of n may be 1/2/3/4, etc., and is not limited herein.

For example, if n is 3, the bit number 3 of the first information field corresponds to the first 8 pieces of information in the first set, and if n is 2, the bit number 2 of the first information field corresponds to the first 4 pieces of information in the first set.

In specific implementation, if n is 1 and there are 8 pieces of information in the feedback delay set, when the feedback delay indication field of the hybrid automatic repeat request of the physical downlink shared channel is configured to be 1bit, the value thereof may be 0 and 1, where 0 is used to indicate the first piece of information in the feedback delay set and 1 is used to indicate the second piece of information in the feedback delay set;

assuming that n is 2 and there are 8 pieces of information in the feedback delay set, when the harq feedback delay indication field is configured to be 2 bits, the value thereof may be 00, 01, 10, 11, 00 to indicate the first piece of information in the feedback delay set, 01 to indicate the second piece of information in the feedback delay set, 10 to indicate the third piece of information in the feedback delay set, and 11 to indicate the fourth piece of information in the feedback delay set.

As can be seen, in this example, different DCI formats use the same feedback delay set, share RRC signaling, and reduce signaling overhead.

In one possible example, the first information field is a beta offset indication beta offset indicator field.

The beta offset indication field is also called a beta offset indication field, a beta offset value indication field, etc.

In one possible example, the number of bits of the beta offset indication field is 0.

In this possible example, the first message is a default beta offset agreed by the protocol.

The preset beta offset can be pre-stored at the terminal device side (for example, the network side indicates configuration, or the protocol convention), and is triggered to be used when the bit number of the first information field is 0.

The preset beta offset may be information of an exclusive configuration other than the first set, and is not limited herein.

As can be seen, in this example, when the bit number of the beta offset indication field is 0, the preset beta offset may be triggered to be used, so as to ensure system stability.

In this possible example, the first information is a beta offset agreed by protocols in the first set.

Wherein the first set may be configured by higher layer signaling.

The beta offset specified by the protocol in the first set may be specifically a first element in the first set.

It can be seen that, in this example, when the bit number of the beta offset indication field is 0, it may be triggered to use a specific beta offset in the first set, so as to ensure system stability.

In this possible example, the number of bits of the beta offset indication field is an integer greater than 0.

When the bit number of the beta offset indication field is greater than 0, the bit number may be 1/2 bits.

In this possible example, the first information is beta offsets in the first set indicated by the beta offset indication field.

The first set is a beta offset set, and elements in the beta offset set may be arranged in a preset order, for example, in an order from small to large or from large to small.

The first elements of the beta offset set can be configured with larger beta offsets, and when the bit number of the beta offset indication field is configured to be less, the elements in front of the beta offset set can be selected.

It can be seen that, in this example, when the bit number of the beta offset indication field is greater than 0, the first information may be determined by the indication information of the beta offset indication field and the first set.

In this possible example, the first set is the set indicated by a first beta offset set configuration of a plurality of beta offset set configurations;

the multiple beta offset set configurations correspond to multiple DCI formats, each beta offset set configuration corresponds to each DCI format, and the multiple DCI formats include the first DCI format.

If the bit number of the feedback delay indication field of the hybrid automatic repeat request of the physical downlink shared channel is 1bit, the number of the elements in the beta offset set may not exceed 2.

If the bit number of the feedback delay indication field of the hybrid automatic repeat request of the physical downlink shared channel is 2 bits, the beta offset set can have no more than 4 elements.

If the bit number of the feedback delay indication field of the hybrid automatic repeat request of the physical downlink shared channel is 3 bits, the beta offset set can have no more than 8 elements.

For example, bit error rate requirements of URLLC and eMBB for a Physical Uplink Shared Channel (PUSCH) are different, and bit error rate requirements of URLLC for PUSCH are higher and reach 10e-5, so a larger beta offset can be used, and bit error rate requirements of eMBB for PUSCH are lower than that of URLLC, so a smaller beta offset is required, so that transmission accuracy of PUSCH can be ensured under the condition of ensuring UCI requirements.

In addition, when the DCI format _1 is not configured with the beta offset set, the DCI format _2 is configured with the beta offset set independently, and does not depend on the beta offset set of the DCI format _1, thereby improving system stability.

As can be seen, in this example, the beta offset set is configured for the DCI format independently, so that different service adjustment transmission policies can be adapted, service requirements are met, and a transmission rate is guaranteed.

In this possible example, the first set is a set indicated by a beta offset set configuration, the first set corresponds to a plurality of DCI formats, and the plurality of DCI formats includes the first DCI format;

the bit number of the first information field is n, the first information field corresponds to the first 2^ n information in the first set, the sequence of the optional information in the first set is a preset sequence, and n is a positive integer.

The value of n may be 1/2/3/4, etc., and is not limited herein.

In a specific implementation, if n is 1 and there are 8 pieces of information in the beta offset set, when the beta offset indication field is configured to be 1bit, its value may be 0 and 1, 0 is used to indicate the first information in the beta offset set, and 1 is used to indicate the second information in the beta offset set;

assuming that n is 2 and there are 8 pieces of information in the beta offset set, when the beta offset indication field is configured to be 2 bits, its value may be 00, 01, 10, 11, 00 to indicate the first information in the beta offset set, 01 to indicate the second information in the beta offset set, 10 to indicate the third information in the beta offset set, and 11 to indicate the fourth information in the beta offset set.

As can be seen, in this example, different DCI formats use the same set of beta offsets, RRC signaling is shared, and signaling overhead is reduced.

In one possible example, the first information field is a Downlink Assignment Index (DAI) field.

In this possible example, the bit number of the downlink allocation index field is 0.

In this possible example, the first information is an index value assigned to a preset downlink agreed by the protocol.

In the specific implementation, in the uplink scheduling DCI, if the downlink allocation index field is 0bit, the new DCI format uses the same processing mode as that of DCI format 0_1, the HARQ acknowledgement HARQ-ACK codebook does not include 2 sub-codebooks, and the parameter corresponding to the downlink allocation index uses a default value of 0.

In the downlink scheduling DCI, if the downlink allocation index field is 0bit, the new DCI format uses the same processing mode as the DCI format 1_1, and the HARQ-ACK codebook does not use the dynamic codebook.

The preset downlink assignment index value may be pre-stored at the terminal device side (for example, the network side indicates configuration, or the protocol convention), and is triggered to be used when the bit number of the first information field is 0.

The predetermined downlink assignment index value may be configured exclusively except for the first set, and is not limited herein.

As can be seen, in this example, when the bit number of the downlink assignment index field is 0, the preset downlink assignment index value may be triggered to be used, so as to ensure system stability.

In this possible example, the first information allocates an index value to a downlink agreed by a protocol in the first set.

Wherein the first set may be configured by higher layer signaling.

The downlink assignment index value agreed by the protocol in the first set may be specifically a first element in the first set.

As can be seen, in this example, when the bit number of the downlink assignment index field is 0, the specific downlink assignment index value in the first set may be triggered to be used, so as to ensure system stability.

In one possible example, the number of bits of the downlink allocation index field is an integer greater than 0.

When the bit number of the downlink assignment index field is greater than 0, the bit number may be 1/2/3 bits.

In this possible example, the first information is an index value of a downlink allocation in the first set indicated by the downlink allocation index field.

Wherein, the first set is a downlink distribution index value set. The elements in the downlink assignment index value set may be arranged in a preset order, for example, in an order from small to large or from large to small.

The first elements of the downlink assignment index value set can be configured as smaller downlink assignment index values, and the elements in front of the downlink assignment index value set can be selected when the bit number configuration of the downlink assignment index field is smaller.

As can be seen, in this example, when the bit number of the downlink allocation index field is greater than 0, the first information may be determined by the indication information of the downlink allocation index field and the first set.

In one possible example, the first set configures the indicated set for a first downlink assigned index value set of a plurality of downlink assigned index value set configurations;

the plurality of downlink assignment index value set configurations correspond to a plurality of DCI formats, each downlink assignment index value set configuration corresponds to each DCI format one to one, and the plurality of DCI formats include the first DCI format.

The DCI formats include DCI format _1, DCI format _2, new DCI format, and the like, which are not limited herein. When the DCI format _1 is not configured with the downlink allocation index value set, the DCI format _2 is configured with the downlink allocation index value set independently, and the downlink allocation index value set of the DCI format _1 is not depended on, so that the system stability is improved.

In specific implementation, the number of bits of different downlink allocation index fields is different from the number of elements in corresponding sets.

If the bit number of the downlink allocation index field is 1bit, there may be no more than 2 elements in the downlink allocation index value set.

If the bit number of the downlink allocation index field is 2 bits, there may be no more than 4 elements in the downlink allocation index value set.

If the bit number of the downlink allocation index field is 3 bits, there may be no more than 8 elements in the downlink allocation index value set.

In one possible example, the first set configures an indicated set for a (single) downlink assignment index value set, where the first set corresponds to a plurality of DCI formats, and the plurality of DCI formats includes the first DCI format;

The value of n may be 1/2/3/4, etc., and is not limited herein.

In a specific implementation, if n is 1 and there are 8 pieces of information in the downlink assignment index value set, when the downlink assignment index field is configured to be 1bit, the value thereof may be 0 and 1, 0 is used to indicate the first information in the downlink assignment index value set, and 1 is used to indicate the second information in the downlink assignment index value set;

assuming that n is 2 and there are 8 pieces of information in the downlink assignment index value set, when the downlink assignment index field is configured to be 2 bits, its value may be 00, 01, 10, 11, 00 to indicate the first piece of information in the downlink assignment index value set, 01 to indicate the second piece of information in the downlink assignment index value set, 10 to indicate the third piece of information in the downlink assignment index value set, and 11 to indicate the fourth piece of information in the downlink assignment index value set.

As can be seen, in this example, different DCI formats use the same downlink assignment index value set to share RRC signaling, thereby reducing signaling overhead.
