The information determining method and the information indicating method provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.
Referring to fig. 2, fig. 2 is a flowchart of an information determining method provided in an embodiment of the present application, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:
step 21: the terminal determines the first RNTI.
In this embodiment, the first Radio Network Temporary Identifier (RNTI) is different from the second RNTI, and the second RNTI is an RNTI used for DCI scrambling in the related art. That is, the first RNTI is an identity different from the existing RNTI.
Step 22: the terminal detects the first DCI using the first RNTI.
Optionally, when detecting the first DCI, the terminal may first perform a DCI Cyclic Redundancy Check (CRC) according to a second RNTI, where the second RNTI may be at least one of a Cell RNTI (Cell RNTI, C-RNTI), a Modulation and Coding Scheme Cell RNTI (MCS-C-RNTI), and a Configured Scheduling RNTI (CS-RNTI). If DCI CRC is successful, the HARQ process number (HARQ process number) indicated in the first DCI is between 0 and 15, and the HARQ process number scheduled at this time can be determined through the 4-bit HARQ process number indication field in the first DCI. And if the DCI CRC check fails, the HARQ process number indicated in the first DCI may be greater than 16, and the first DCI needs to be detected using the first RNTI. It should be noted that the DCI format corresponding to the search space of the terminal in this embodiment may be selected as any one or more of 0-0,0-1,0-2,1-0,1-1 and 1-2, and the DCI format is not limited in this embodiment. Except for the HARQ process number, the interpretation of other fields of the DCI successfully detected by the terminal through checking the first RNTI is completely the same as the interpretation of the DCI successfully detected by the terminal through checking the second RNTI.
Step 23: when the first DCI is detected, the terminal determines a first HARQ process number indicated by the first DCI according to the first RNTI and the HARQ process number indication field in the first DCI.
It can be understood that when the first DCI is detected by using the first RNTI, it may be indicated that the first HARQ process number indicated by the first DCI is greater than the second HARQ process number indicated by the HARQ process number indication field in the first DCI, and at this time, the first HARQ process number indicated by the first DCI may be determined according to the first RNTI and the HARQ process number indication field in the first DCI.
In one embodiment, the first HARQ process number is greater than or equal to 16, that is, greater than or equal to the number of HARQ processes that can be indicated in the HARQ process number indication field in the current DCI.
In this embodiment of the application, after determining the first RNTI, the terminal may detect the first DCI using the first RNTI, and when the first DCI is detected, determine the first HARQ process number indicated by the first DCI according to the first RNTI and the HARQ process number indication field in the first DCI. Therefore, the number of HARQ processes which can be indicated by the DCI can be increased by means of RNTI scrambling, for example, the number can be increased from 16 to 32, 64, 128 and the like, so that the indication requirement of the DCI on the required HARQ process number can be met on the premise of not increasing the blind detection times.
In this embodiment, the first RNTI may be determined according to protocol predefining and/or configuration information of a network side. Optionally, the determining the first RNTI may include:
the terminal acquires the first information and determines the first RNTI according to the first information.
Wherein the first information may include at least one of:
m first offset values between the first RNTI and the second RNTI;
a second offset value and a first value L; wherein an offset value between the first RNTI and the second RNTI is equal to a second offset value multiplied by L, L being equal to {1,2 \8230;, L }; namely, the offset value between the first RNTI and the second RNTI is in a multiple relation with the second offset value;
a predefined RNTI;
the values of the N highest a bits of the first RNTI.
Note that the first RNTI is an RNTI for the determined HARQ process number. The second RNTI is an RNTI for other functions, such as a conventional RNTI for DCI scrambling, different from the first RNTI. M, L, N and a are integers of 1 or more. In particular, due to the structural form of the RNTI, a is an integer less than or equal to 8.
In this embodiment of the application, according to different determination manners of the first RNTI, that is, according to different first information, the terminal may determine the first HARQ process number indicated by the first DCI in different manners, which is described in detail below.
In a first mode
In this first mode, the first information includes: m first offset values between the first RNTI and the second RNTI. Further, the process of determining the first HARQ process number by the terminal may include: firstly, determining M first RNTIs according to the second RNTI and M first deviation values; then, performing CRC check on the first DCI by using the M first RNTIs, and determining a target RNTI for successfully checking the first DCI; the target RNTI is the nth value of the M first RNTIs, and n is smaller than or equal to M; and finally, when the first DCI is detected, determining a first HARQ process number according to the n and the HARQ process number indication field. In this way, by using the offset value between the first RNTI and the second RNTI, the required first RNTI can be determined based on the existing second RNTI, so as to determine the first HARQ process number indicated by the first DCI.
Optionally, the value of M may be calculated by the following formula: (number of HARQ processes configured by the terminal-first preset value)/first preset value. The first preset value may be selected as the number of HARQ processes that can be indicated in the HARQ process number indication field in the first DCI, for example, 16. For example, the first preset value is 16, the number of HARQ processes configured by the base station for the UE is 32, and the first information includes only one first offset value, where the first offset value may be any one value of 0001-FFF 2. For another example, the first preset value is 16, and the number of HARQ processes configured for the UE by the base station is 64, the first information may include three first offset values, that is, three different values, and the three different values may be arbitrarily selected from 0001-FFF 2. The aforementioned 0001 and FFF2 are expressed by 16.
Optionally, the determining M first RNTIs according to the second RNTI and the M first offset values may include: the terminal determines a first RNTI corresponding to each first offset value by adopting any one of the following modes:
first RNTI = second RNTI + first offset value;
first RNTI = second RNTI — first offset value.
Optionally, the determining the first HARQ process number according to n and the HARQ process number indication field may include:
the terminal calculates the product of n and a first preset value to obtain a second numerical value;
the terminal determines a second HARQ process number indicated by the HARQ process number indication field in the first DCI;
and the terminal calculates the sum of the second numerical value and the second HARQ process number to obtain the first HARQ process number.
The first preset value may be set based on actual requirements, and may be selected as the number of HARQ processes that can be indicated in the HARQ process number indication field in the first DCI, for example, 16.
For example, if the number of HARQ processes that can be indicated by the HARQ process number indication field in a DCI is 16, n is equal to 1, and the HARQ process number indication field in the DCI is 0011, the number of HARQ processes indicated by the DCI is 19, that is, 16 × 1+3=19, and 3 is the HARQ process number indicated by the indication field 0011. Thereby, an indication of a HARQ process number larger than 16 may be achieved.
Mode two
In the second mode, the first information includes: a second offset value and a first value L. Further, the process of determining the first HARQ process number by the terminal may include: firstly, multiplying L by the second offset value to obtain L third offset values; wherein L is equal to {1,2 \8230;, L }, and L first RNTIs are determined according to the second RNTI and L third offset values; then, performing CRC check on the first DCI by using the L first RNTIs, and determining a target RNTI which is successfully checked on the first DCI; the target RNTI is the nth value of the L first RNTIs, and n is smaller than or equal to L; and finally, when the first DCI is detected, determining a first HARQ process number according to the n and the HARQ process number indication field. In this way, by using the offset value between the first RNTI and the second RNTI, the required first RNTI can be determined based on the existing second RNTI, so as to determine the first HARQ process number indicated by the first DCI.
Alternatively, the second offset value may be any one of 0001-FFF 2. The value of L can be calculated by the following formula: (number of terminal-configured HARQ processes-16)/16. For example, if the number of HARQ processes configured by the base station for the UE is 32, L may take the value of 1. For another example, if the number of HARQ processes configured by the base station for the UE is 64, L may take the value of 3.
In one embodiment, assuming that the second offset value is 0004 and l is equal to 3, the obtained 3 third offset values are: 0004. 0008 and 000C. The 0004, 0008 and 000C are expressed by 16.
Optionally, the determining the L first RNTIs according to the second RNTI and the L third offset values may include: the terminal determines, for each third offset value, a first RNTI corresponding to the third offset value in any one of the following manners:
the first RNTI = the second RNTI + the third offset value;
first RNTI = second RNTI — third offset value.
Optionally, the determining the first HARQ process number according to n and the HARQ process number indication field may include:
the terminal calculates the product of n and a first preset value to obtain a second numerical value;
the terminal determines a second HARQ process number indicated by the HARQ process number indication field in the first DCI;
and the terminal calculates the sum of the second numerical value and the second HARQ process number to obtain the first HARQ process number.
The first preset value may be set based on actual requirements, and may be selected as the number of HARQ processes that can be indicated in the HARQ process number indication field in the first DCI, for example, 16.
For example, if the number of HARQ processes that can be indicated by the HARQ process number indication field in a DCI is 16, n is equal to 1, and the HARQ process number indication field in the DCI is 0011, the number of HARQ processes indicated by the DCI is 19, that is, 16 × 1+3=19, and 3 is the HARQ process number indicated by the indication field 0011. Thereby, an indication of a HARQ process number larger than 16 may be achieved.
Mode III
In a third aspect, the first information includes: a predefined RNTI. The predefined RNTI may be one or more RNTIs that are predefined. For example, see table 1 below, which shows three predefined first RNTIs, namely HARQ-C-RNTI, HARQ-MCS-C-RNTI, and HARQ-CS-RNTI. It should be noted that the names of the HARQ-C-RNTI, the HARQ-MCS-C-RNTI, and the HARQ-CS-RNTI are only examples, and other names may be adopted, and the embodiment does not limit this.
TABLE 1
Figure BDA0003008589240000101
Further, the process of determining the first HARQ process number by the terminal may include: firstly, a predefined RNTI is determined as a first RNTI; then, detecting the first DCI by using a predefined RNTI; and finally, when the first DCI is detected, determining a first HARQ process number according to the HARQ process number bit field and a first preset value. In this way, by means of the predefined RNTI, the required first RNTI can be determined easily and conveniently, so as to determine the first HARQ process number.
Note that, the first preset value may be set based on actual requirements, and may be selected as the number of HARQ processes that can be indicated in the HARQ process number indication field in the first DCI, for example, 16. The detecting of the first DCI using the predefined RNTI may detect the first DCI using at least one of an HARQ-C-RNTI, an HARQ-MCS-C-RNTI, and an HARQ-CS-RNTI.
Optionally, the determining the first HARQ process number according to the HARQ process number indication field and the first preset value may include: and the terminal determines a second HARQ process number indicated by the HARQ process number indication field in the first DCI, and calculates the sum of the second HARQ process number and the first preset value to obtain the first HARQ process number.
For example, if the number of HARQ processes that can be indicated by the HARQ process number indication field in a DCI is 16, the HARQ process number indication field in the DCI is 0011, and the first RNTI is a predefined RNTI, the number of HARQ processes indicated by the DCI is 19, that is, 16+3=19, and the 3 is the HARQ process number indicated by the indication field 0011. Thereby, an indication of a HARQ process number larger than 16 may be achieved.
Mode IV
In a fourth aspect, the first information includes: the values of the N highest a bits of the first RNTI. Further, the process of determining the first HARQ process number by the terminal may include: firstly, respectively carrying out combined processing on the values of the N highest a bits and the second RNTI to obtain N first RNTIs; then, performing CRC (cyclic redundancy check) on the first DCI by using the N first RNTIs (radio network temporary identifiers), and determining a target RNTI for successfully verifying the first DCI; the target RNTI is the nth value of the N first RNTIs, and N is smaller than or equal to N; and finally, determining the first HARQ process number according to the n and the HARQ process number indication domain. In this way, by using the obtained value of the highest a bit of the first RNTI, the required first RNTI may be determined based on the existing second RNTI, so as to determine the first HARQ process number indicated by the first DCI.
The above-mentioned combination treatment may be a combination. When the value of the highest a bit of the first RNTI and the second RNTI are jointly processed for joint processing, the obtained first RNTI may be represented as: (value of the highest a-bit, second RNTI). For example, if N is 1, a is 1, the highest 1-bit value of the first RNTI is 1, the value of the second RNTI is F001, and the F001 is in a 16-ary expression form, the first RNTI obtained through the joint processing is: 1F001. For another example, if N is 3, a is 2,3 values of the highest 2 bits are 01, 10, and 11, respectively, the value of the second RNTI is F001, and the F001 is in a 16-ary representation form, then the first RNTIs obtained through the joint processing are: 1F001, 2F001, 3F001.
Optionally, the determining the first HARQ process number according to n and the HARQ process number indication field may include:
the terminal performs joint processing on the nth value of the N values of the highest a bit and the HARQ process number indication domain in the first DCI to obtain a first indication domain;
and the terminal determines the value indicated by the first indication field as a first HARQ process number.
For example, if n is equal to 1, the corresponding 1 st value is 1, and the HARQ process number indication field in the first DCI is 0010, the first indication field after the joint processing is 10010, and the indicated first HARQ process number is 18. For example, if n is equal to 3, the corresponding 3 rd value is 11, and the HARQ process number indication field in the first DCI is 0010, the first indication field after the joint processing is 110010, and the indicated first HARQ process number is 50. Thereby, an indication of a HARQ process number larger than 16 may be achieved.
Optionally, a is an integer greater than or equal to 1 and less than or equal to 8. The above a may be determined using the following formula:
a＝log2(total)-log2 (X)
wherein, the total is the HARQ process number configured by the terminal; x is a first preset value, for example, the number of HARQ processes that can be indicated in the HARQ process number indication field in the DCI.
For example, if the number of HARQ processes configured by the terminal is 32, and the number of HARQ processes that can be indicated in the HARQ process number indication field in the dci is 16, a is equal to 1.
It should be noted that the first information may be obtained based on preconfigured information, and is not issued by the network device, and the terminal may determine the first RNTI according to the first information and the HARQ process number, so that compared with a manner in which the network issues the first information, signaling overhead may be saved.
In an optional implementation manner, the terminal determines the highest a bit of the first RNTI used for DCI CRC check according to the maximum HARQ process number configured by the base station, where the highest a bit is all values that the a bits can represent except 0. For example, the number of HARQ processes that can be indicated by the HARQ process number indication field 4bits in the DCI is 16, if the number of HARQ processes configured by the base station is 32, the number of the HARQ process number indication field configured by the base station is 5, a is 1, and the highest a bit is 1; and if the number of the HARQ processes configured by the base station is 64, the number of the indication fields of the number of the HARQ processes configured by the base station is 6, a is 2, and the highest a bit is 01, 10 or 11.
In this case, the first RNTI is (the highest a-bit, second RNTI). The terminal checks DCI CRC according to the first RNTI and determines a first HARQ process number, which specifically comprises the following steps: the terminal combines the highest a bit with 4bits of the HARQ process number indication domain in the DCI to obtain an (a + 4) indication domain indicating the first HARQ process number, and further determines the first HARQ process number. For example, when the number of HARQ processes is 32, a is 1, and if the HARQ process number indication field 4bit in the DCI is 0010, the indication field of the first HARQ process number is 10010, and the first HARQ process number is 18. For another example, when the number of HARQ processes is 64, a is 11, and if the HARQ process number indication field 4bits in the DCI is 0010, the indication field of the first HARQ process number is 110010, and the first HARQ process number is 50.
In another optional embodiment, the terminal determines the highest a bit of the first RNTI for DCI CRC check according to the maximum HARQ process number configured by the base station, where the highest a bit is all values that can be represented by a bits. For example, the number of HARQ processes that can be indicated by the HARQ process number indication field 4bits in the DCI is 16, if the number of HARQ processes configured by the base station is 32, the number of HARQ processes configured by the base station is 5, a is 1, the highest a bit is 0 or 1,0 corresponds to the HARQ process number of 0-15, and 1 corresponds to the HARQ process number of 16-31; and if the number of the HARQ processes configured by the base station is 64, the number of the indication domain of the number of the HARQ processes configured by the base station is 6, a is 2, the highest a bit is 00, 01, 10 and 11, the number of the HARQ process corresponding to 00 is 0-15, the number of the HARQ process corresponding to 01 is 16-31, the number of the HARQ process corresponding to 10 is 32-47, and the number of the HARQ process corresponding to 11 is 48-63.
In this case, the first RNTI is (the highest a-bit, second RNTI). The terminal checks DCI CRC according to the first RNTI and determines a first HARQ process number, which specifically comprises the following steps: the terminal combines the highest a bit with the 4bits of the HARQ process number indication field in the DCI to obtain the (a + 4) indication field indicating the first HARQ process number, and further determines the first HARQ process number. For example, when the number of HARQ processes is 32, a is 1, if the HARQ process number indication field 4bit in the DCI is 0010, the indication field of the first HARQ process number is 10010, and the first HARQ process number is 18; or, if a is 0, and 4bits of the HARQ process number indication field in the dci is 0010, the indication field of the first HARQ process number is 0010, and the first HARQ process number is 2. For another example, when the number of HARQ processes is 64, a is 11, and if the HARQ process number indication field 4bits in the DCI is 0010, the indication field of the first HARQ process number is 110010, and the first HARQ process number is 50. Thus, compared with the above embodiment, since a takes a value when the HARQ process number is less than 16 and the HARQ process number is greater than or equal to 16, the processing modes of the terminals can be unified, and the number of the highest a bits can be determined according to the first information and the configured HARQ process number, so that the DCI CRC check modes of the HARQ process number less than 16 and the HARQ process number greater than or equal to 16 are unified without using the second RNTI for DCI CRC check.
In this embodiment, the first information may be obtained by the terminal from a network side device, such as a base station. The acquiring of the first information may include:

Optionally, the terminal may determine whether to detect the DCI using the first RNTI according to information acquired from the network side. The method in this embodiment may further include:
and the terminal acquires the second information and determines to detect the first DCI by using the first RNTI according to the second information. Therefore, before the first DCI is detected, the first DCI can be determined to be detected by using the first RNTI with the assistance of the second information, so that the DCI can be detected quickly and accurately.
Wherein the second information may include at least one of:
HARQ configuration information; for example, the HARQ configuration information includes a HARQ process number greater than 16;

In one embodiment, the second information does not include an enabling indication for detecting the DCI with the first RNTI, and the terminal determines whether to detect the DCI with the first RNTI and determines the number of HARQ processes according to the configured number of HARQ processes. For example, when the number of HARQ processes configured through the RRC message is 32, the terminal may determine to detect DCI using the first RNTI without an additional indication.
In another embodiment, the second information includes an enable indication for detecting DCI using the first RNTI, and the terminal root terminal determines to detect DCI using the first RNTI.
Optionally, the terminal may obtain the second information by at least one of:
RRC message, MAC CE.
It should be noted that the first information and the second information may be carried in the same message, such as an RRC message, or may be carried in different messages. Alternatively, the first information and the second information may be carried in the same MAC CE, or may be carried in different MAC CEs.
In the embodiment of the present application, when the network side device configures the HARQ process number for the terminal, the capability and implementation complexity of the terminal need to be considered. Based on this, in order to ensure feasibility of network configuration, the terminal may report a capability indication, where the capability indication is used to indicate the number of HARQ processes supported by the terminal, or the capability indication is used to indicate the HARQ process capability supported by the terminal.
Referring to fig. 3, fig. 3 is a flowchart of an information indication method provided in an embodiment of the present application, where the method is applied to a network side device, and as shown in fig. 3, the method includes the following steps:
step 31: the network side equipment determines a first HARQ process number to be indicated.
In this embodiment, the first HARQ process number may be greater than or equal to 16, that is, greater than or equal to the number of HARQ processes that can be indicated in the HARQ process number indication field in the current DCI.
Step 32: and when the first HARQ process number is larger than the HARQ process number which can be indicated by the HARQ process number indication field in the DCI, the network side equipment determines the first RNTI.
The first RNTI is different from a second RNTI which is used for DCI scrambling in the prior art. That is, the first RNTI is an identity different from the existing RNTI.
Step 33: and the network side equipment scrambles the CRC of the DCI to be transmitted by using the first RNTI to obtain the first DCI.
And the HARQ process number indicated by the first DCI is the first HARQ process number.
Step 34: and the network side equipment transmits the first DCI.
It should be noted that the DCI format scheduled by the network side device in this embodiment may be any one or more of 0-0,0-1, 1-0, and 1-1, which is not limited herein.
In this embodiment of the present application, after determining a first HARQ process number to be indicated, when the first HARQ process number is greater than the HARQ process number that can be indicated by the HARQ process number indication field in the DCI, the network side device may determine a first RNTI, scramble a CRC of the DCI to be transmitted using the first RNTI, obtain the first DCI, and transmit the first DCI. Therefore, the number of HARQ processes which can be indicated by the DCI can be increased by means of RNTI scrambling, for example, the number can be increased from 16 to 32, 64, 128 and the like, so that the indication requirement of the DCI on the number of the required HARQ processes can be met on the premise of not increasing the number of blind detection times.
In this embodiment, the first RNTI may be determined according to protocol predefining and/or configuration information of a network side. Optionally, the determining the first RNTI may include:
the network side equipment acquires the first information and determines the first RNTI according to the first information.
Wherein the first information may include at least one of:
m first offset values between the first RNTI and the second RNTI;
a second offset value and a first value L; the offset value between the first RNTI and the second RNTI is equal to the second offset value multiplied by L, wherein L is equal to {1,2 \8230, L }, namely the offset value between the first RNTI and the second RNTI is in a multiple relation with the second offset value;
a predefined RNTI;
the values of the N highest a bits of the first RNTI.
Note that M, L, N, and a are integers greater than or equal to 1. In particular, due to the structural form of the RNTI, a is an integer less than or equal to 8.
In this embodiment of the application, according to different determination manners of the first RNTI, that is, according to different first information, the network side device may determine the first HARQ process number indicated by the first DCI in different manners, which is described in detail below.
In a first mode
In this first mode, the first information includes: m first offset values between the first RNTI and the second RNTI. Further, the process of the network side device determining the first RNTI may include: firstly, determining a target value n according to a first HARQ process number; n is less than or equal to M; then, the first RNTI is determined according to the nth first offset value of the M first offset values and the second RNTI.
Optionally, the value of M may be calculated by the following formula: (number of terminal-configured HARQ processes-16)/16. For example, if the number of HARQ processes configured by the base station for the UE is 32, the first information includes only one first offset value, and the first offset value may be any one of 0001-FFF 2. For another example, if the number of HARQ processes configured by the base station for the UE is 64, the first information may include three first offset values, that is, three different values, where the three different values may be arbitrarily selected from 0001-FFF 2. The aforementioned 0001 and FFF2 are expressed by 16.
Optionally, the determining the first RNTI according to the nth first offset value of the M first offset values and the second RNTI may include:
the network side equipment determines the first RNTI in any one of the following modes:
the first RNTI = the second RNTI + the nth first offset value;

Optionally, in this manner, the first HARQ process number may be equal to a sum of the third value and the second HARQ process number; the third value is equal to the product of n and the first preset value, and the second HARQ process number is the HARQ process number indicated by the HARQ process number indication field in the first DCI. The first preset value may be set based on actual requirements, and may be selected as the number of HARQ processes that can be indicated in the HARQ process number indication field in the first DCI, for example, 16.
Optionally, the target value n may be determined by: the network side equipment determines a target value n by adopting the following formula:
Figure BDA0003008589240000171
wherein Y denotes a first HARQ process number. b represents the number of HARQ processes that can be indicated in the HARQ process number indication field in the DCI, and is 16, for example.
Figure BDA0003008589240000172
Representing a rounded up symbol.
For example, if the number of the first HARQ process is 17, n has a value of 1, i.e. equal to the rounding-up of (17-16)/16. For another example, if the first HARQ process number is 40, then n has a value of 2, i.e. equal to the rounding-up of (40-16)/16.
For another example, if the first HARQ process number is 20, then n has a value of 1, i.e. equal to the rounding-up of (20-16)/16; in this case, the base station determines the first RNTI according to the 1 st first offset value of the M first offset values and the second RNTI. That is, the first RNTI = second RNTI + 1 st first offset value, or the first RNTI = second RNTI-1 st first offset value.
For another example, if the first HARQ process number is 40, then n has a value of 2, i.e. equal to the rounding-up of (40-16)/16; in this case, the base station determines the first RNTI according to the 2 nd first offset value among the M first offset values and the second RNTI. That is, the first RNTI = second RNTI + 2 nd first offset value, or the first RNTI = second RNTI-2 nd first offset value.
Mode two
In the second mode, the first information includes: a second offset value and a first value L. Further, the process of the network side device determining the first RNTI may include: firstly, determining a target value n according to a first HARQ process number; n is less than or equal to M; then, calculating the product of the second offset value and n to obtain a fourth offset value; and finally, determining the first RNTI according to the fourth offset value and the second RNTI.
Optionally, the determining the first RNTI according to the fourth offset value and the second RNTI may include:
the network side equipment determines the first RNTI in any one of the following modes:
the first RNTI = the second RNTI + a fourth offset value;
first RNTI = second RNTI — fourth offset value.
Optionally, in this way two, the first HARQ process number may be equal to the sum of the third value and the second HARQ process number; and the third numerical value is equal to the product of n and the first preset value, and the second HARQ process number is the HARQ process number indicated by the HARQ process number indication field in the first DCI. The first preset value may be set based on actual requirements, and may be selected as the number of HARQ processes that can be indicated in the HARQ process number indication field in the first DCI, for example, 16.
Note that, the manner of determining the target value n in this manner is the same as the above-mentioned manner, and is not described herein again.
Mode III
In a third aspect, the first information includes: a predefined RNTI, such as shown in table 1 above. The predefined RNTI may be a predefined RNTI or RNTIs. Further, the network side device determines a predefined RNTI as the first RNTI.
Optionally, in this way three, the first HARQ process number may be equal to a sum of the first preset value and the second HARQ process number; and the second HARQ process number is the HARQ process number indicated by the HARQ process number indication field in the first DCI.

Note that the method of determining the target value n in this manner is the same as the above-mentioned method one, and is not described herein again.
For the above first to third modes, the formula for scrambling DCI CRC by using the first RNTI may be:
c k ＝b k ，k＝0,1,2,……,A+6；
c k ＝(b k +x rnti ， k-A-7 )mod 2，k＝A+7,A+8,……,A+23；
wherein the content of the first and second substances,b k the CRC check bits are 24 bits, which indicate the result of CRC action on the load (payload) in the DCI to be transmitted. A denotes the number of bits of a payload in DCI to be transmitted. c. C k Indicates that the first RNTI pair b is used k The result after scrambling, where the first RNTI has 16bits, x rnti，0 、x rnti，1 ……x rnti，15 ，x rnti，0 Represents the Most Significant Bit (MSB); x is a radical of a fluorine atom rnti ， k-A-8+a Representing the bits in the first RNTI for the last 16bits, mod represents the modulo operation symbol.
Mode IV
In a fourth aspect, the first information includes: the values of the N highest a bits of the first RNTI. Further, the process of determining the first RNTI by the network side device may include: firstly, determining a target value n according to a first HARQ process number; n is less than or equal to M; then, the first RNTI is determined according to the value of the nth highest a bit in the values of the N highest a bits and the second RNTI.
Optionally, when the first RNTI is determined, the network side device may perform joint processing on the value of the nth highest a bit and the second RNTI to obtain the first RNTI. The joint processing may be a combination. For example, assuming that the value of the nth highest a bit is 1, the value of the second RNTI is F001, and the F001 is in a 16-ary representation form, the first RNTI obtained after the joint processing is: 1F001. For another example, if the value of the nth most significant a bit is 11, the value of the second RNTI is F101, and the F001 is in 16-ary expression form, the first RNTI obtained after the joint processing is: 3F101.
Optionally, in this fourth mode, the first HARQ process number may be indicated by a first indication field, where the first indication field is obtained by performing joint processing on the nth highest a-bit value and the HARQ process number indication field in the first DCI. For example, if the value of the nth highest a bit is 1, and the harq process number indication field is 0010, the first indication field is 10010. For another example, if the nth highest a bit is 11, the harq process number indication field is 1010, and the first indication field is 111010.
Note that the method of determining the target value n in this manner is the same as the above-mentioned method one, and is not described herein again.
Optionally, in this way four, the network side device may scramble the CRC of the DCI to be transmitted by using the following formula, to obtain the first DCI:
c k ＝b k ，k＝0,1,2,……,A+7-a；
c k ＝(b k +x rnti ， k-A-8+a )mod 2，k＝A+8-a,A+9-a,……,A+23；
wherein, b k And the CRC check bit of the result after the load in the DCI to be transmitted is subjected to CRC is 24 bits. A denotes the number of bits of the payload in the DCI to be transmitted. c. C k Indicates that the first RNTI is used for b k As a result of scrambling, the bits of the first RNTI are 16+ a, i.e. a bits are added before the MSB of the original second RNTI. x is a radical of a fluorine atom rnti ， k-A-8+a The bits in the first RNTI representing the last 16bits, mod the modulo operation symbol.
In this embodiment, the first information may be sent to the terminal by a network side device, such as a base station. That is, after acquiring the first information, the network side device may send the first information to the terminal.
Optionally, the network side device may obtain the first information through at least one of the following:

In the embodiment of the present application, when the network side device configures the HARQ process number for the terminal, the capability and implementation complexity of the terminal need to be considered. Based on this, in order to ensure feasibility of network configuration, the network side device may receive a capability indication reported by the terminal, where the capability indication is used to indicate the number of HARQ processes supported by the terminal, or the capability indication is used to indicate the HARQ process capability supported by the terminal.
For example, the base station may determine whether to send second information to the terminal according to the supportable HARQ process number reported by the terminal, where the second information is used to determine whether to detect DCI using the first RNTI, that is, to detect whether the first DCI is received correctly, and the HARQ process number indicated by the first DCI is greater than or equal to 16.
