Detailed Description

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

(1) The network side device is a device for providing a wireless communication function for the terminal, and includes but is not limited to: a gbb in 5G, a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved node B or home node B, HNB), a BaseBand Unit (BBU), a transmission point (TRP), a Transmission Point (TP), a mobile switching center (msc), and the like. The base station in the present application may also be a device that provides the terminal with a wireless communication function in other communication systems that may appear in the future.

(2) A terminal is a device that can provide voice and/or data connectivity to a user. For example, the terminal device includes a handheld device, an in-vehicle device, and the like having a wireless connection function. Currently, the terminal device may be: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like.

The existing Release 15NR has only one downlink SPS configuration or uplink CG configuration within one bandwidth segment (BWP). Therefore, when the downlink SPS configuration or the uplink CG configuration is released, the UE only needs to identify the DCI as the DCI for releasing the downlink SPS configuration or the uplink CG configuration. In the research of Rel-16URLLC, it is necessary to enhance the downlink SPS configuration and uplink CG configuration, and support multiple activated downlink SPS configurations or multiple activated uplink CG configurations within one BWP. The DCI also needs to indicate which downlink SPS configuration or uplink CG configuration is or is not released when the downlink SPS configuration or uplink CG configuration is released.

However, there is no clear scheme for how to indicate the released downlink SPS/uplink CG configuration through DCI, so based on this, a technical scheme for releasing multiple downlink SPS or CG in one bandwidth part is proposed.

For example, in the prior art, the downlink SPS configuration is released through DCI format (format)1_ 0; the uplink CG configuration is released via DCIformat 0_0, as shown in table 1.

Table 1 identifies downlink SPS and uplink CG release bit field settings

The inventor researches and discovers that when a plurality of activated downlink SPS configurations or uplink CG configurations exist in the prior art, if part of the configurations are released, the prior art cannot realize the configuration.

In view of this, the embodiments of the present invention provide a solution. In the process of describing the technical solutions provided in the embodiments of the present application, the implementation of a system formed by a network side device and a terminal side is described to better understand the implementation of the solutions provided in the embodiments of the present invention. Then, examples of the separate implementations of both will also be given separately. However, such an explanation does not mean that the two devices must be implemented in cooperation or separately, and actually, when the terminal and the network device are implemented separately, the problems of the terminal device and the network device are solved separately, and when the two devices are used in combination, a better technical effect is obtained.

It should be noted that, since the behaviors of the network side device and the terminal side are generally corresponding, the system will be mainly described for the sake of simplicity, and a person skilled in the art should be able to understand the implementation of the corresponding side based on common knowledge.

Accordingly, referring to fig. 1, the technical solution provided by the embodiment of the present invention is applied to a communication system, where the system includes a network side device 11 and a terminal 10, and mainly releases downlink SPS configuration or uplink CG configuration through the following technical solution.

In the embodiment of the present invention, when the network side device indicates which downlink SPS configuration/uplink CG configuration is to be released, the terminal may indicate, through different DCI formats, the downlink SPS configuration or uplink CG configuration that needs to be released. In this embodiment of the present invention, the release of the downlink SPS configuration is indicated by using the first DCI format, for example, the DCI format 1_0 is used for the indication. The release of the uplink CG configuration is indicated by the second DCI format, for example, by using DCI format 0_ 0. Of course, it should be noted that, in specific implementation, the first DCI format and the second DCI format may be determined according to actual requirements, which is not limited in this embodiment of the present invention.

When there are multiple downlink SPS configurations or multiple uplink CG configurations in one bandwidth portion, the network side device may indicate which downlink SPS configurations/uplink CG configurations are specifically released through the specified information field of the DCI with the corresponding format. Can be implemented as follows:

the method comprises the steps that network side equipment determines a configuration identifier of configuration to be released, wherein the configuration to be released comprises at least one downlink semi-persistent scheduling (SPS) configuration or at least one uplink configuration authorization (CG) configuration;

the first DCI format and the second DCI format each include the following specific bit fields, including:

hybrid automatic repeat request HARQ process number (HARQ process number);

redundancy version (Redundancy version);

modulation and coding scheme (Modulation and coding scheme), and,

Frequency domain resource allocation field (Frequency domain resource allocation).

Specific configuration of specific bit field of uplink CG configuration is shown in table 2, and specific configuration of specific bit field of downlink SPS configuration is shown in table 3. In table 2, the second DCI format is DCI format 0_0, and the first DCI format is DCI format 1_ 0.

Table 2 DCI format 0_0 bit field setting for identifying uplink CG release

Table 3 DCI format 1_0 bit field setting for identifying downlink SPS release

In one embodiment, in the first DCI format, the designated information field is at least one of:

time domain resource allocation (Time domain resource assignment) -its bit field has 4 bits;

virtual resource block VRB to physical resource block PRB mapping (VRB-to-PRB mapping) -its bit field has 1 bit;

new data indicator (New data indicator) -whose bit field has 1 bit;

downlink allocation sequence number (Downlink assignment index), whose bit field has 2 bits;

scheduling transmit power control (TPC command for scheduled PUCCH) of a physical uplink control channel PUCCH having 2 bits in a bit field;

PUCCH resource indicator (PUCCH resource indicator) -its bit field has 3 bits;

Timing indication (PDSCH-to-HARQ feedback indicator) of the PDSCH-to-HARQ feedback, whose bit field has 3 bits.

Accordingly, in one embodiment, in the second DCI format, the designated information field is at least one of:

frequency hopping flag (Frequency hopping flag) — its bit field has 1 bit;

new data indicator (New data indicator) -whose bit field has 1 bit;

scheduling transmission power control (TPC command for scheduled PUSCH) of a physical uplink shared channel PUSCH, which has 2 bits in a bit field.

In one embodiment, the designated information fields may be one or more of the information fields described above. The specific adoption of which information fields are used as the designated information fields can be realized through protocol convention. The network side device may also indicate the designated information field adopted by the terminal.

The following describes in detail how to indicate which downlink SPS/uplink CG configurations are released by specifying the information field.

It should be noted that, in the embodiments of the present invention, if not specifically stated, the term "configuration" in the following refers to a downlink SPS configuration or an uplink CG configuration. Specifically, how to indicate whether to configure downlink SPS/uplink CG by specifying information fields can be implemented in the following three ways:

And in the first mode, the bit field value of the designated information field is adopted to determine which downlink SPS configuration or uplink CG configuration is released.

That is, the indication information of the configuration identifier is a bit field value of the designated information field. The first mode can be divided into the following three schemes:

scheme 1And the bit domain value and the configuration identifier in the designated information domain have a one-to-one correspondence relationship.

That is, for the downlink SPS configuration, in the corresponding first DCI format, the bit field value in the designated information field and the downlink SPS configuration identifier have a one-to-one correspondence relationship.

For the uplink CG configuration, in the corresponding second DCI format, a bit field value in the designated information field and an uplink CG configuration identifier have a one-to-one correspondence relationship.

Correspondingly, when the terminal releases the downlink SPS configuration or the uplink CG configuration, the terminal may be configured to determine a configuration identifier indicated by the indication information according to a corresponding relationship between the bit field value and the configuration identifier.

This scheme is explained below using an uplink CG configuration example.

Assuming that the protocol supports 16 uplink CG configuration identifiers at most, a 4-bit time domain resource allocation bit field in the protocol agreed DCI format 0_0 is used to indicate a released uplink CG configuration, and 16 different values thereof respectively indicate a released uplink CG configuration identifier, as shown in table 4 below.

Table 4 time domain resource allocation bit field value and configuration identifier corresponding relationship

Time domain resource allocation bit domain value	Uplink CG configuration identification
		0000	Upstream CG configuration 0
0001	Upstream CG configuration 1
		0010	Upstream CG configuration 2
0011	Upstream CG configuration 3
		0100	Upstream CG configuration 4
0101	Upstream CG configuration 5
		0110	Upstream CG configuration 6
0111	Upstream CG configuration 7
		1000	Uplink CG configuration 8
1001	Upstream CG configuration 9
		1010	Upstream CG configuration 10
1011	Upstream CG configuration 11
		1100	Upstream CG configuration 12
1101	Upstream CG configuration 13
		1110	Upstream CG configuration 14
1111	Upstream CG configuration 15

It should be noted that, if the protocol supports fewer uplink CG configuration identifiers, for example, supports at most 8 uplink CG configuration identifiers, 8 different values of the lower 3 bits or the upper 3 bits of the 4-bit time domain resource allocation bit field may be used to respectively indicate a released uplink CG configuration.

The terminal may determine the uplink CG configuration identifier indicated by the indication information according to the correspondence in table 4, thereby performing an operation of releasing the corresponding uplink CG configuration.

In addition, as shown in the embodiment in table 4, if the specified information field is an information field other than the specific bit field, the bit field value is a bit field value in the specified information field;

of course, if the designated information field is at least two information fields other than the specific bit field, the value of the bit field is the value of the bit sequence obtained after the bit fields of the at least two information fields are spliced according to the preset rule.

Such as: when uplink CG configuration release is performed, 3-bit sequence value is required, and a frequency hopping identifier (1 bit) and transmission power control (2 bits) of a scheduling PUSCH can be selected and spliced according to a preset rule to obtain a bit sequence value. For example, the transmission power control of the scheduled PUSCH may be set to the previous hopping flag to obtain a 3-bit sequence after splicing, or the transmission power control of the scheduled PUSCH may be set to the previous hopping flag to obtain a 3-bit sequence after splicing. The arrangement of the designated information field is not specifically limited, and the selected designated information field is not specifically limited as long as the bit sequence with the required bit number, i.e., the value range of the required bit field, can be obtained.

Scheme 2,The bit field value and the configuration identification set have a one-to-one correspondence relationship

For downlink SPS configuration, in a corresponding first DCI format, a bit field value in an appointed information field and a downlink SPS configuration identifier set have a one-to-one correspondence relationship.

For the uplink CG configuration, in the corresponding second DCI format, a bit field value in the designated information field and the uplink CG configuration identifier set have a one-to-one correspondence relationship.

Correspondingly, when the terminal releases the downlink SPS configuration or the uplink CG configuration, the terminal can be executed to determine a configuration identifier set indicated by the indication information according to the corresponding relation between the bit domain value and the configuration identifier; and the bit field value and the configuration identifier set have a one-to-one correspondence relationship.

This scheme is explained below using an uplink CG configuration example.

It is assumed that 16 different values of the 4-bit time domain resource allocation bit field in the DCI format 0_0 respectively correspond to an uplink CG configuration identifier set, as shown in table 5 below.

Table 5 correspondence between time domain resource allocation bit field and configuration identifier set

The terminal may determine the uplink CG configuration identifier set according to the correspondence in table 5, thereby performing an operation of releasing the uplink CG configuration. The configuration contained in the configuration set can be determined by protocol convention, network side notification or configuration parameters. The determination of the configured parameters may be to configure a configuration set with the same value for a specific parameter. For example, the network side configures one HARQ process offset value for each CG, and the UE configures the CGs with the same HARQ process offset value as one configuration set based on the configuration of the network side.

Scheme 3, In the value domain of the bit domain value, part of the bit domain value has a one-to-one correspondence relationship with the configuration identifier, and the other part of the bit domain value has a one-to-one correspondence relationship with the configuration identifier set, wherein the configuration identifier set has at least two configuration identifiers.

For downlink SPS configuration, in a corresponding first DCI format, in a value domain of a bit domain value in an appointed information domain, a part of the bit domain value has a one-to-one correspondence relationship with a configuration identifier, and the other part of the bit domain value has a one-to-one correspondence relationship with a configuration identifier set, wherein the configuration identifier set has at least two configuration identifiers.

For uplink CG configuration, in a corresponding second DCI format, in a value domain of a bit domain value in an assigned information domain, part of the bit domain values and configuration identifiers have a one-to-one correspondence relationship, and another part of the bit domain values and a configuration identifier set have a one-to-one correspondence relationship, where the configuration identifier set has at least two configuration identifiers.

Correspondingly, when the terminal releases the downlink SPS configuration or the uplink CG configuration, the method may be executed to determine at least one configuration identifier indicated by the indication information according to a corresponding relationship between the bit field value and the configuration identifier.

This scheme is explained below using an uplink CG configuration example.

16 different bit domain values of a 4-bit time domain resource allocation bit domain in the DCI format 0_0, wherein a part of the bit domain values respectively correspond to an uplink CG configuration identifier, and the other part of the bit domain values respectively correspond to a configuration identifier set. The corresponding relation can be determined by agreement, or by the notification of the network side equipment to the terminal, or by configured parameters. As shown in table 6 below.

Table 6 correspondence between time domain resource allocation bit field and configuration identifier group

The terminal may determine the uplink CG configuration identifier to be released according to the correspondence in table 6, thereby releasing the corresponding uplink CG configuration.

Mode two, release downlink SPS configuration or uplink CG configuration by bit field bitmap indication

That is, the indication information is a bitmap in the specified information domain, wherein each bit in the bitmap corresponds to one configuration identifier or one configuration identifier set; for each bit in the bitmap, the agreed-upon value of that bit indicates the release configuration.

Scheme 1The bit in the bitmap in the designated information domain and the configuration identifier have a one-to-one correspondence relationship.

That is, for the downlink SPS configuration, in the corresponding first DCI format, each bit in the bit field bitmap in the designated information field has a one-to-one correspondence with the downlink SPS configuration identifier.

For the uplink CG configuration, in the corresponding second DCI format, each bit of the bit field bitmap in the designated information field has a one-to-one correspondence with the uplink CG configuration identifier.

Correspondingly, the terminal releases the downlink SPS configuration and can execute the downlink SPS configuration corresponding to one configuration identifier corresponding to the bit taking the value as the appointed value in the bit domain bitmap if each bit corresponds to one configuration identifier;

the terminal releases the uplink CG configuration and can execute the step of releasing the uplink CG configuration corresponding to one configuration identifier corresponding to the bit with the value being the appointed value in the bit domain bitmap if each bit corresponds to one configuration identifier.

This scheme is explained below using an uplink CG configuration example.

If the total 8 bits of 4 specified information domains are controlled by adopting time domain resource allocation, frequency hopping identification, new data indication and transmission power of a scheduling PUSCH, the form of bitmap can be adopted to indicate that 8 uplink CG configurations are released. The corresponding relation between each bit in the 8-bit bitmap and an uplink CG configuration identifier can be agreed by a protocol, and when the bit corresponding to the uplink CG configuration is set to be 1, the corresponding uplink CG configuration is released. For example, 8 bits correspond to CG configurations 1 to 8 from the lowest bit to the highest bit, respectively, and if the 8-bit bitmap is set to 00010101, it is known that configurations 1, 3, and 5 are released.

If 8 downlink SPS configurations are released, time domain resource allocation, VRB to PRB mapping, new data indication and total 8 bits of 4 information domains of downlink allocation sequence numbers are adopted to indicate and release 8 downlink SPS configurations in a bitmap form; for example, the 16 downlink SPS configurations can be released by adopting time domain resource allocation, VRB-to-PRB mapping, new data indication, downlink allocation sequence number, transmission power control of scheduling PUCCH, PUCCH resource indication, and timing indication from PDSCH to HARQ feedback, and using a bitmap form to indicate 16 bits of 7 information fields.

The terminal can release the corresponding downlink SPS configuration according to the corresponding relation between the bit in the bitmap and the configuration identifier.

Scheme 2The bit domain bitmap in the designated information domain and the configuration identification set have a one-to-one correspondence relationship.

That is, for the downlink SPS configuration, in the corresponding first DCI format, a bit in a bit field bitmap in the designated information field has a one-to-one correspondence relationship with the downlink SPS configuration identifier set.

For the uplink CG configuration, in the corresponding second DCI format, a bit in a bit field bitmap in the designated information field has a one-to-one correspondence with the uplink CG configuration identifier set.

Correspondingly, the terminal releasing the downlink SPS configuration may be executed to release the downlink SPS configuration corresponding to one configuration identifier set corresponding to a bit taking the value as the agreed value in the bit domain bitmap if each bit corresponds to one configuration identifier set.

The terminal releases the uplink CG configuration and can execute the step of releasing the uplink CG configuration corresponding to one configuration identifier set corresponding to the bit with the appointed value in the bit domain bitmap if each bit corresponds to one configuration identifier set.

For example, the predetermined value may be 1, that is, a bit in bitmap with a value of 1 identifies that the corresponding downlink SPS configuration or uplink CG configuration needs to be released.

This scheme is explained below using an uplink CG configuration example.

If 8 bits in total of 4 information fields controlled by time domain resource allocation, frequency hopping identification, new data indication and transmission power of a scheduling PUSCH are adopted, 8 uplink CG configuration identification sets are released by adopting a bitmap form indication, and the protocol appoints the corresponding relation between each bit in the 8-bit bitmap and one uplink CG configuration identification set. For example, a default value indicating that the uplink CG configuration needs to be released is 1, and if the 8-bit bitmap is set to 00010101, the corresponding release configuration identifier set 1, configuration identifier set 3, and configuration identifier set 5 may be known according to the bitmap information, where the configuration identifier set includes a plurality of uplink CG configuration identifiers.

Scheme 3And in the bit domain bitmap, part of bits and the configuration identifications have a one-to-one correspondence relationship, and the other part of bits and the configuration identification set have a one-to-one correspondence relationship, wherein the configuration identification set has at least two configuration identifications.

That is, for the downlink SPS configuration, in the corresponding first DCI format, in the bit field bitmap, a part of bits has a one-to-one correspondence relationship with the configuration identifier, and another part of bits has a one-to-one correspondence relationship with the configuration identifier set, where the configuration identifier set has at least two configuration identifiers, namely, downlink SPS.

For uplink CG configuration, in a corresponding first DCI format, in a bit domain bitmap, a part of bits and configuration identifiers have a one-to-one correspondence, and another part of bits and a configuration identifier set have a one-to-one correspondence, where the configuration identifier set has at least two configuration identifiers.

Accordingly, the terminal releasing the downlink SPS configuration may be performed as:

releasing downlink SPS configuration corresponding to one configuration identifier corresponding to the bit with the value being the appointed value in the bit domain bitmap aiming at the bit of one configuration identifier corresponding to each bit;

The terminal release uplink CG configuration may be performed as:

releasing uplink CG configuration corresponding to a configuration identifier corresponding to a bit with a value being an appointed value in a bit domain bitmap aiming at a bit with a configuration identifier corresponding to each bit;

The terminal can release the configuration according to the corresponding relation between the bitmap and the configuration identifier.

And thirdly, releasing continuous downlink SPS configuration or uplink CG configuration in a joint coding mode.

Specifically, if the network side device releases the specified number of configurations starting from the specified configuration identifier, the indication information is joint encoding of the specified configuration identifier and the specified number, and each joint encoding result corresponds to a group of parameter combinations, where the parameter combinations include the specified configuration identifier and the specified number.

That is, for the downlink SPS configuration, in the corresponding first DCI format, the joint coding result obtained by joint coding in the specified information field and the specified number of consecutive downlink SPS configuration identifiers of the downlink SPS have a one-to-one correspondence relationship.

For the uplink CG configuration, in the corresponding second DCI format, the joint coding result obtained by joint coding in the designated information field and the consecutive uplink CG configuration identifiers of the designated number have a one-to-one correspondence relationship.

Correspondingly, the terminal determines the assigned configuration identification and the assigned quantity corresponding to the joint code; determining a specified number of configuration identifiers in succession from the specified configuration identifier as the configuration identifier indicated by the indication information.

Specifically, joint encoding can be achieved by:

first determining whether the specified number is less than a preset threshold:

if the value is less than or equal to the preset threshold value, obtaining a joint coding result by adopting the following formula (1); wherein the preset threshold is half of the total configuration quantity plus 1;

SLIV＝A(L-1)+S，0<L≤A-S (1)

if the value is larger than the preset threshold value, obtaining a joint coding result by adopting the following formula (2);

SLIV＝A(A-L+1)+(A-1-S)；0<L≤A-S (2)

wherein, in equations (1) and (2), the SLIV represents a joint coding result; the A represents the sum of the configuration quantity of the downlink SPS or the configuration quantity of the uplink CG; the L represents a specified number; the S represents a specific configuration identifier.

In a specific implementation, the configuration identifier may be specified to start from any position, for example, a plurality of consecutive downlink SPS configurations may be released from the configuration identifier 0, or a plurality of consecutive downlink SPS configurations may be released from the configuration identifier 5.

The following description will take the example of releasing the uplink CG configuration flag. Specifically, assuming that the initial uplink CG configuration identifier is D (D is numbered from 0), the designated CG designates the configuration identifier as S, and the designated release number is L, values (SLIV) after joint coding are as follows. For example, for 16 uplink CG configurations (L ≦ 16), it can be known from the above equations (1) and (2) that the SLIV has a value range of 0 to 135, and 8 bits are used for indication. Specifically, for example, if the uplink CG configuration 0-3 is to be released, S is 0, L is 4, and SLIV is 48, the result of the joint coding is set to 00110000, which corresponds to four consecutive configuration identifiers, that is, the configuration identifiers 0 to 3 are released.

If (L-1) is less than or equal to 8,

SLIV＝16(L-1)+S

otherwise

SLIV＝16(16-L+1)+(16-1-S)

Wherein L is more than 0 and less than or equal to 16-S

Taking the uplink CG configuration identifier as an example for explanation, for example, a group of consecutive uplink CG configurations in 8 uplink CG configurations is released by using time domain resource allocation, frequency hopping identifier, and a total 6-bit indication of 3 specified information fields indicated by new data.

If (L-1) is less than or equal to 4,

SLIV＝8(L-1)+S

otherwise

SLIV＝8(8-L+1)+(8-1-S)

Wherein L is more than 0 and less than or equal to 8-S

By adopting the method, one or more uplink CG configuration identifiers can be released, wherein the uplink CG configuration identifiers must be consecutive uplink CG configuration identifiers, such as: the assigned configuration identifiers are 1, the assigned number is 2, and it can be known through calculation that the joint coding result is 9, which corresponds to 001001, and the configuration corresponding to 2 continuous configuration identifiers, from the corresponding release configuration identifier 1 to the configuration identifier 2, is total.

And releasing a group of uplink CG configurations with continuous identifiers in 16 uplink CG configurations by adopting time domain resource allocation, frequency hopping identifiers, new data indication and 8-bit indication of 4 specified information domains for controlling transmission power of a scheduling PUSCH. In this way, one or more uplink CG configurations can be released, where configuration identifiers of the multiple uplink CG configurations must be consecutive uplink CG configuration identifiers.

For example, the downlink SPS configuration identifier is used as an example, for example, a group of downlink SPS configurations with continuous identifiers in 8 downlink SPS configurations is released by using time domain resource allocation, VRB to PRB mapping, and a total 6-bit indication of 3 specified information fields of new data indication. In this way, one or more downlink SPS configurations can be released, wherein the configuration identifier of the multiple downlink SPS configurations must be a continuous downlink SPS.

And releasing a group of downlink SPS configuration identifiers with continuous identifiers in 16 downlink SPS configurations by adopting time domain resource allocation, VRB to PRB mapping, new data indication and 8-bit indication in a 4-bit domain of a downlink allocation sequence number. In this way, one or more downlink SPS configurations can be released, wherein the configuration identifiers of the multiple downlink SPS configurations must be consecutive downlink SPS.

The terminal can determine which downlink SPS configuration or uplink CG configuration is released according to the joint coding result so as to carry out the operation of releasing the corresponding configuration.
