The embodiment of the application provides a control information transmission method which is applied to a terminal. Fig. 2 is a first flowchart illustrating a control information transmission method according to an embodiment of the present application; as shown in fig. 2, the method includes:

step 101: the terminal receives control information for data scheduling.

Step 102: the terminal analyzes the control information based on RNTI, and the RNTI is first RNTI or second RNTI used for scrambling redundant check bits of the control information.

In this embodiment, as an implementation manner, the terminal receives a signal carrying control information and a scrambled redundant check bit, and obtains control information for data scheduling based on the signal; as another implementation, the terminal receives control information carrying scrambled redundancy check bits. Wherein the number of the redundancy check bits corresponding to the control information may be at least one.

In this embodiment, the RNTI used for parsing the control information may be configured to descramble the control information based on the first RNTI and/or the second RNTI or obtain a redundancy check bit based on the descrambled redundancy check bit and perform verification determination, and the first RNTI or the second RNTI corresponding to the redundancy check bit passing the verification is used for parsing the control information.

Wherein the control information is related to the RNTI; different data schedules correspond to different RNTIs and thus to different control information. It is understood that the control information includes a variety of information, and for the configuration information, the first RNTI and the second RNTI correspond to different information, respectively, which includes the number of information and/or the content of the information being different.

Here, the first RNTI and the second RNTI are both used for terminal-specific data scheduling. The terminal obtains a Cyclic Redundancy Check (CRC) code based on the first RNTI or the second RNTI descrambling control information, checks the CRC code, and determines the first RNTI or the second RNTI which passes the Check.

The first RNTI and the second RNTI are any two RNTIs in an RNTI data set; the RNTI data set comprises at least two RNTIs. It is to be understood that there are at least two RNTIs associated with control information for data scheduling, and that different data schedules correspond to different RNTIs, corresponding to different control information.

The first RNTI is a Cell Radio Network Temporary Identifier (C-RNTI).

In this embodiment, the control information includes at least one of the following information: a Downlink Control Information Format (DCI Format), a Redundancy Version (Redundancy Version), a Hybrid Automatic Repeat reQuest Process Number (HARQ Process Number), a Channel state Information reQuest (CSI reQuest), a timing relationship (PDSCH-to-HARQ) corresponding to a physical Downlink shared Channel and HARQ, a physical uplink Control Channel Resource Indicator (PUCCH Resource Indicator), and an offset parameter (beacon offset).

Wherein, when the control information includes at least one of Redundancy Version, HARQ Process Number, CSI request, PDSCH-to-HARQ, PUCCH Resource Indicator, beacon offset, the same kind of information respectively corresponding to the first RNTI and the second RNTI includes different numbers of information and/or different contents of information.

For example, the Redundancy Version and the HARQ Process Number may be included in control information corresponding to the first RNTI and the second RNTI; the Redundancy Version in the control information corresponding to the first RNTI may include four versions 0, 2, 3, 1, and the number corresponding to included information is 4. The Redundancy Version in the control information corresponding to the second RNTI may include two versions of {0, 3} or {0, 2}, and then the number corresponding to the included information is 2; the amount and content of the information contained is different. And the HARQ Process Number in the control information corresponding to the first RNTI may include 16 processes, and the HARQ Process Number in the control information corresponding to the second RNTI may include 4 processes, so that the Number and content of the included information are different.

When the control information includes the DCI Format, the effective lengths of the DCI formats respectively corresponding to the first RNTI and the second RNTI are different, or the domain information contained in the DCI Format is different.

By adopting the technical scheme of the embodiment of the application, the RNTI related to the control information is determined by the network equipment, and then the control information used for data scheduling is determined, namely different RNTIs are determined by different data scheduling, so that data transmission between the terminal and the network equipment based on the control information corresponding to the data scheduling is realized, independent optimized transmission of data according to different service types is realized, the transmission efficiency is greatly improved, and the transmission reliability and delay requirements of the data of different service types are met.

The embodiment of the application also provides a control information transmission method which is applied to network equipment. Fig. 3 is a second flowchart illustrating a control information transmission method according to an embodiment of the present application; as shown in fig. 3, the method includes:

step 201: the method comprises the steps that network equipment determines control information used for data scheduling and RNTI adopted by redundant check bit scrambling of the control information; the control information is related to the RNTI; the RNTI comprises a first RNTI or a second RNTI.

Step 202: and the network equipment sends the control information.

In this embodiment, the network device may determine different RNTIs based on different data scheduling, and further determine control information related to the RNTIs. In practical applications, the network device may determine the RNTI based on the service type, further determine the information included in the control information, and further determine the amount and/or content of the information included in the control information. It is understood that the control information includes a plurality of kinds of information, and the first RNTI and the second RNTI correspond to different information, respectively, for the same kind of information, the different information including the number of information and/or the content of the information being different.

Here, the first RNTI and the second RNTI are any two RNTIs in an RNTI data set; the RNTI data set comprises at least two RNTIs. It is to be understood that there are at least two RNTIs associated with control information for data scheduling, and that different data schedules correspond to different RNTIs, corresponding to different control information. The network device may select the corresponding RNTI based on the current data scheduling, and then determine the corresponding control information.

Here, the network device determines the control information and determines a redundancy check bit corresponding to the control information, where the redundancy check bit may be specifically represented by CRC; and the network equipment scrambles the CRC based on the determined RNTI, performs channel coding modulation on the control information and the scrambled redundant check bits, and maps the control information and the scrambled redundant check bits to time-frequency resources to send.

As an embodiment, the network device signals the control information and the scrambled redundancy check bits; as another implementation, the network device sends control information, where the control information carries the scrambled redundancy check bits.

In this embodiment, the control information includes at least one of the following information: DCI Format, Redundancy Version, HARQ Process Number, CSI request, PDSCH-to-HARQ, PUCCH Resource Indicator, Betaoffset.

When the control information includes at least one of reduction Version, HARQ Process Number, CSI request, PDSCH-to-HARQ, PUCCH Resource Indicator, and Betaoffset, the same type of information respectively corresponding to the first RNTI and the second RNTI in the control information includes different numbers of information and/or different contents of information.

The embodiment of the application also provides a control information transmission method. Fig. 4 is an interaction flow diagram of a control information transmission method according to an embodiment of the present application; as shown in fig. 4, the method includes:

step 301: the network equipment determines control information used for data scheduling and RNTI adopted by redundancy check bit scrambling of the control information.

Step 302: and the network equipment sends the control information.

Step 303: and the terminal analyzes the control information based on RNTI, wherein the RNTI is a first RNTI or a second RNTI used for scrambling redundant check bits of the control information.

The specific implementation process of each step in this embodiment may specifically refer to the foregoing embodiment, and is not described here again.

The control information including each information will be described in detail below.

1、Redundancy Version

As an embodiment, the length of the Redundancy Version in the control information scrambled based on the first RNTI may be 2 bits, and four values of the Redundancy Version correspond to four versions of 0, 2, 3, and 1. The length of the Redundancy Version field in the control information scrambled based on the second RNTI can be 1bit, and two values of the Redundancy Version field correspond to {0, 3} or {0, 2} versions in the Redundancy Version. That is, the number of pieces of information of the Redundancy Version respectively corresponding to the first RNTI and the second RNTI is different, and the content of the information is also different.

In this embodiment, {0, 3} can obtain a sufficient coding diversity gain for data with a low code rate. Therefore, the {0, 3} is configured for dynamic selection, which not only can satisfy sufficient Incremental Redundancy (IR) combining gain, but also can reduce control signaling overhead, and for URLLC service, reduce control signaling overhead, and is also beneficial to the reliability of control signaling. Therefore, for URLLC traffic, the control information may be scrambled based on the second RNTI; for the eMBB, the control information may be scrambled based on the first RNTI.

2、HARQ Process Number

As an implementation manner, the length of the HARQ Process Number in the control information scrambled based on the first RNTI may be 4 bits, and 16 values thereof correspond to 0-15 HARQ processes or 1-16 HARQ processes. The length of the HARQ Process Number in the control information scrambled based on the second RNTI can be 2 bits, and 4 values of the HARQ Process Number correspond to 0-3 HARQ processes or 1-4 HARQ processes.

The HARQ entity and/or HARQ buffer corresponding to the HARQ Process Number in the control information scrambled based on the first RNTI is independent from the HARQ entity and/or HARQ buffer corresponding to the HARQ Process Number in the control information scrambled based on the second RNTI even if the HARQ Process numbers are the same.

As another embodiment, the HARQ entity and/or HARQ buffer corresponding to the HARQ Process Number in the control information scrambled based on the first RNTI and the HARQ entity and/or HARQ buffer corresponding to the HARQ Process Number in the control information scrambled based on the second RNTI are independent of each other even though the HARQ Process numbers are the same.

That is, the Number of pieces of information of HARQ Process numbers respectively corresponding to the first RNTI and the second RNTI is different, and the contents of the information are also different.

In the embodiment, for services or data with a high processing speed, only a few HARQ processes are needed, and no transmission resource waste is caused; reducing HARQ Process, reducing corresponding downlink signaling overhead, and for URLLC service, completing detection (meeting time delay requirement) quickly; therefore, for the URLLC service, the control information can be scrambled based on the second RNTI, and a small number of HARQ Process bits can not only avoid resource waste, but also be beneficial to the reliability of control signaling; for the eMBB, the control information may be scrambled based on the first RNTI.

3、CSI request

As an embodiment, based on the CSI request in the control information scrambled by the first RNTI, the length may be 4 bits, and 16 values thereof correspond to 16 CSI reports (CSI reports). At least one of the 16 CSI reports comprises a longer PUSCH symbol, or is based on multiple non-zero power (NZP) -CSI/Zero Power (ZP) -CSI as a measurement resource to support measurement under various signal and interference conditions. The length of the CSI Request in the control information scrambled based on the second RNTI may be 1bit, and 2 values of the CSI Request correspond to 2 CSI reports. At least one of the 2 CSI ports is based on a Demodulation Reference Signal (DMRS) as a measurement resource and/or a time domain measurement window, and is equal to downlink data, so as to reduce signaling overhead and improve downlink control signaling reliability. That is, the numbers of pieces of information of CSI requests respectively corresponding to the first RNTI and the second RNTI are different, and the contents of the information are also different.

In this embodiment, for the URLLC service, the control information may be scrambled based on the second RNTI; for the eMBB, the control information may be scrambled based on the first RNTI.

4、PDSCH-to-HARQ

As an embodiment, based on the PDSCH-to-HARQ in the control information scrambled by the first RNTI, the length may be 3 bits, and 8 values thereof correspond to {3, 4, 5, 6, 8, 12, 16, 20 }. The length of PDSCH-to-HARQ in the control information scrambled based on the second RNTI can be 1bit, and 2 values of the length correspond to {0, 1 }. That is, the number of pieces of information of PDSCH-to-HARQ respectively corresponding to the first RNTI and the second RNTI is different, and the contents of the information are also different.

In the embodiment, for transmission with harsh delay requirements, the PDSCH-to-HARQ feedback needs to be implemented as soon as possible, otherwise, the HARQ feedback has no meaning and does not need to be fed back. Therefore, PDSCH-to-HARQ may be selected with fewer occasions and with fewer bits, e.g., selecting the second RNTI to scramble the control information corresponding to PDSCH-to-HARQ. For transmission with low delay requirement, the flexibility of uplink and downlink resource allocation and the efficiency of uplink control transmission are considered, a plurality of optional PDSCH-to-HARQ occasions exist, and more bits are needed to improve the system efficiency, for example, the control information scrambled by the first RNTI corresponding to the PDSCH-to-HARQ is selected. In addition, fewer PDSCH-to-HARQ bits are beneficial to improve the reliability of control information transmission.

Therefore, for URLLC traffic, the control information may be scrambled based on the second RNTI; for the eMBB, the control information may be scrambled based on the first RNTI.

5、PUCCH Resource Indicator

As an embodiment, the length of the PUCCH Resource Indicator in the control information scrambled based on the first RNTI may be 3 bits, and 8 values thereof correspond to those shown in table 1. Table 1 includes different lengths/PUCCH formats, different symbol numbers (numbers of symbols), different Physical Resource Block (PRB) offset values (offsets), and different Initial CS index sets (Initial CS index sets), so as to meet the requirement of delay reliability, and meanwhile, the system is paired with other users for transmission, thereby improving the system transmission efficiency. The length of the PUCCH Resource Indicator in the control information scrambled based on the second RNTI may be 3 bits, and 8 values thereof correspond to those shown in table 2. Table 2 includes different Starting symbols (Starting symbols), which improves the flexibility of the time domain resource of the control channel and meets the requirement of low delay.

TABLE 1

TABLE 2

6、Beta_offset

In one embodiment, the length of the { Beta _ offset for HARQ-ACK, Beta _ offset for CSI } set corresponding to Beta _ offset in the control information scrambled based on the first RNTI may be 2 bits, and 4 values thereof correspond to the { Beta _ offset for HARQ-ACK, Beta _ offset for CSI } set shown in table 3. Table 3 contains values for Beta _ offset that are all greater than 1. The length of the { Beta _ offset for HARQ-ACK, Beta _ offset for CSI } set corresponding to Beta _ offset in the control information scrambled based on the second RNTI may be 2 bits, and 4 values thereof correspond to the { Beta _ offset for HARQ-ACK, Beta _ offset for CSI } set shown in table 4. Table 4 contains values for Beta _ offset less than 1. For data with high transmission reliability requirements, the reliability requirements of the control channel with respect to the data are comparable or lower, and therefore it is reasonable to include some smaller values. Otherwise, the transmission efficiency of the control channel is too low, and resources are wasted. Therefore, for URLLC traffic, the control information may be scrambled based on the second RNTI; for the eMBB, the control information may be scrambled based on the first RNTI.

TABLE 3

Beta_offset indicator	Beta_offset for HARQ-ACK	Beta_offset for CSI
			00	1	1.25
01	4	1.75
			10	31	5
11	126	10

TABLE 4

Beta_offset indicator	Beta_offset for HARQ-ACK	Beta_offset for CSI
			00	1	1.25
01	4	1.75
			10	0.5	0.6
11	0.01	0.05

To sum up, in order to meet the service requirement of URLLC, the second RNTI scrambling control information as shown above is used, reducing the bits; the reduced bits may be used to indicate other information, such as a Carrier Indicator (Carrier Indicator), a CSI request, a BandWidth Part (BWP, BandWidth Part) Indicator, or to extend some existing fields, such as Time Domain Resource allocation (Time Domain Resource Assignment), PUCCH Resource Indicator, Downlink Assignment Index (DAI), etc., to improve flexibility of transmission.

7、DCI format

As an embodiment, based on a field value included in control information scrambled by the first RNTI, a Fallback DCI column as shown in table 5 or table 6; a New DCI column as shown in table 5 or table 6 based on a field value contained in control information scrambled by the second RNTI. The New DCI reduces a partial domain compared to the Fallback DCI because it is not necessary for transmission of a specific service or cannot significantly improve transmission efficiency. But some fields are additionally added, such as Carrier Indicator, CSI request, BWP Indicator, or some fields are extended, such as Time Domain Resource Assignment, PUCCH Resource Indicator, DAI, etc., to improve the flexibility of transmission, reduce the transmission delay, and improve the transmission efficiency. Therefore, for URLLC traffic, the control information may be scrambled based on the second RNTI; for the eMBB, the control information may be scrambled based on the first RNTI.
