Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a resource indication method, a resource determination method, a device, a base station, and a terminal.

Background technique

In the LTE (Long Term Evolution) PUCCH (Physical Uplink Control Channel) resource indication, an implicit resource indication is used for a PUCCH carrying an ACK (Acknowledgement or Response)/NACK (no acknowledgement or no response) The method, that is, the PDCCH (Physical Downlink Control Channel) of the PDSCH (Physical Downlink Shared Channel), the minimum CCE (Control Channel Element) corresponding to a specific PUCCH resource, this minimum The CCE is also referred to as a starting CCE, and when the ACK/NACK is fed back, the resources of the PUCCH are used to transmit the ACK/NACK signal. Therefore, at the initial access, the PDCCH scheduling message 4 (message 4) is mapped to one PUCCH resource to carry the ACK/NACK feedback. As shown in FIG. 1, M1-M4 represent four steps of initial access, corresponding to four messages (message1, message2, message3, and message4), and for message4, the ACK/NACK signal is transmitted in the subsequent PUCCH.

In the technical discussion of the 5G NR (5G new air interface), there are two PUCCH resource indication methods, and one is an explicit indication method, which is to first indicate an allocation of the terminal UE by using RRC (Radio Resource Control) signaling. Resource set, and then use the downlink control information DCI to inform the terminal of a specific resource index (index); the other method is implicit resource indication mode, that is, the LTE method is used, and the corresponding minimum of the PDCCH is used. The index number of the CCE is mapped to a specific PUCCH resource. Both methods have advantages and disadvantages, the explicit method is more flexible, and the implicit method can save signaling overhead.

In the initial indication of the PUCCH resource indication of the message 4, there are currently some methods. The basic idea is to use the system information in combination with the DCI (Downlink Control Information) indication, or the random access response message RAR to indicate, but There is no clear indication of how to use the system information, how to use the indication information of the DCI, and how to combine the steps of the implicit indication, so these methods are not complete. If the RAR indication method is adopted, the channel structure of the RAR needs to be greatly adjusted, and only a group of users can be instructed, so this method also has a great defect.

In summary, the related resource method for message 4 does not have the same signaling framework as the RRC connected state method, or the indication information of the RMSI (Remaining minimum system information) is not clear, or the RAR is The channel structure is greatly adjusted, causing significant impact on the standard, so these methods are not effective resource indication methods.

Detailed ways

The technical problems, the technical solutions, and the advantages of the present invention will be more clearly described in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 2, some embodiments of the present disclosure provide a resource indication method, where the method includes steps 21-22.

Step 21: The resource configuration parameter of the target uplink control channel PUCCH resource set is indicated to the terminal by using the system information, where the target PUCCH resource set is used to transmit the uplink acknowledgement ACK/non-acknowledgement NACK feedback of the downlink information in the random access procedure;

In this step, the resource configuration parameter of the target PUCCH resource set includes: a format type of the PUCCH, a start symbol of the PUCCH, a length of the PUCCH, a frequency domain of the PUCCH, a frequency offset, a resource offset value of the PUCCH, and a cyclic shift. The minimum interval, the number of frequency domain resource blocks available for PUCCH transmission, and at least two of the frequency domain resource blocks available for PUCCH transmission.

It should be noted that the foregoing resource configuration parameters need to be able to determine a unique target PUCCH resource set. The above system information may be RMSI (Remaining minimum system information).

Step 22: Instruct the terminal to indicate one PUCCH resource in the target PUCCH resource set by using a downlink control channel PDCCH.

The foregoing embodiment of the present disclosure first uses system information to indicate resource configuration parameters of a target PUCCH resource set, and the terminal can determine one target PUCCH resource set according to the resource configuration parameter; and then use the PDCCH to indicate one PUCCH resource in the target PUCCH resource set. The terminal can use the one PUCCH resource indicated by the PDCCH to transmit the uplink acknowledgement ACK/non-acknowledgement NACK feedback of the downlink information in the random access procedure.

Optionally, step 21 includes:

Step 211: Send system information to the terminal, where the system information carries resource configuration parameters of the target PUCCH resource set; or

Step 212: Send system information to the terminal, where an index of the preset bit field of the system information is used to indicate a resource configuration parameter of the target PUCCH resource set.

Optionally, in the foregoing embodiment of the disclosure, the N bit information field of the system information RMSI is used to indicate a resource configuration parameter of the target PUCCH resource set. N is an integer greater than or equal to 4, and optionally, N is equal to 4.

The format type of the PUCCH (that is, the format type) occupies a 1-bit information field. Since the number of information bits of the ACK/NACK is at most 1 bit in the initial access phase, the PUCCH format type has two options; for example, “0” indicates Format 0; "1" indicates format 1.

In order to limit the number of bits, in some embodiments of the present disclosure, the start symbol of the PUCCH and the length of the PUCCH are indicated together, that is, the start symbol of the PUCCH and the length of the PUCCH occupy a 1-bit information field. For example, for format 0, since the total subframe length is 14 symbols, 13/1 and 12/2 can be used, where 13/1 indicates that the start symbol is 13, and the PUCCH length is 1 symbol; 12/2 indicates The initial symbol is 12 and the PUCCH length is 2 symbols. For format 1, consider the 14/0 and 10/4 options, which have the same meaning as format 0.

The frequency domain of the PUCCH indicates whether the frequency hopping occupies the 1-bit information field. If it is frequency hopping, the PUCCH is generally divided into two parts in the time domain and transmitted in different frequency bands. For example, “0” means no frequency hopping and “1” means frequency hopping.

The resource offset value of the PUCCH occupies a 1-bit information field, where the information is used to indicate a starting offset value of the PUCCH resource; since the PUCCH resource of the initial access user may share resources with other accessed users, in order to reserve other users For the PUCCH resource, the offset value of the PUCCH resource needs to be set; for example, the semi-persistent scheduling SPS user.

The minimum interval of the cyclic shift CS occupies a 1-bit information field or a 2-bit information field, and the information is used to indicate the interval of the cyclic shift CS of different users. For a sequence, the maximum number of CSs available is 12, and the size of the interval determines the number of users supported.

The number of frequency domain resource blocks available for PUCCH transmission or the frequency domain resource blocks available for PUCCH transmission may occupy a 1-bit information field, respectively.

It should be noted that, when there is a 4-bit information field in the system information to indicate the resource configuration parameter, the information included in the resource configuration parameter does not need to be indicated at the same time, so as to ensure that the total information bit field length occupied by the resource configuration parameter does not exceed 4.

Further, in the foregoing embodiment of the present disclosure, when the resource information of the target PUCCH resource set is carried in the system information, each parameter in the resource configuration parameter uses a different bit field indication. That is, different bit fields (also referred to as information fields) are used to indicate different parameters. When the resource information of the target PUCCH resource set is carried in the system information, the use of the 4-bit information field of the system information is as shown in Table 1:

Table 1

As shown in Table 1, the 4-bit information field of the system information is used to carry the resource configuration parameter. The resource configuration parameters carried in the system information 1 include: 1 bit indicates the PUCCH format type, 1 bit indicates the PUCCH start symbol and the PUCCH length, and the 2 bit indicates the loop. The minimum interval of the shift; the resource configuration parameters carried by the system information 2 include: 1 bit indicates the PUCCH format type, 1 bit indicates the PUCCH resource offset value, 2 bits indicates the minimum interval of the cyclic shift, and the resource configuration parameters carried in the system information 3 include: 1 bit Indicates the PUCCH format type, 1 bit indicates the PUCCH start symbol and PUCCH length, 1 bit indicates whether to hop, and 1 bit indicates the minimum interval of cyclic shift.

Further, in the foregoing embodiment of the present disclosure, when the index of the preset bit field of the system information is used to indicate the resource configuration parameter of the target PUCCH resource set, the index of the preset bit field is used to indicate a The group is associated with a resource configuration parameter; it may also be referred to as a joint encoding of at least two parameters included in the resource configuration parameter.

When the index of the preset bit field of the system information is used to indicate the resource configuration parameter of the target PUCCH resource set, since the preset bit field is 4 bits, the preset bit field of the system information has at most 16 different types. Index, if the PUCCH length is 2 characters, the frequency hopping is always on; or if the switch supporting the frequency hopping is needed, it can be realized by reducing the number of minimum intervals of the cyclic shift, for example, setting the minimum of the cyclic shift The interval is 2 or 3. Optionally, the mapping relationship between the index of the preset bit field of the system information (that is, the 4-bit information field) and the resource configuration parameter is as shown in Table 2:

Table 2

As shown in Table 2, when the index of the preset bit field of the system information is “0”, the resource configuration parameters included in the system information are: the PUCCH format is 0, the start symbol is 12, the PUCCH length is 2, and frequency hopping exists. The minimum interval for cyclic shift is 1. The parameters corresponding to other indexes are not enumerated one by one.

Alternatively, the mapping relationship between the index of the preset bit field of the system information (ie, the 4-bit information field) and the resource configuration parameter is as shown in Table 3 (the minimum interval for setting the cyclic shift is 2 or 3):

table 3

As shown in Table 3, when the index of the preset bit field of the system information is "0", the resource configuration parameters included in the system information are: PUCCH format is 0, start symbol is 12, PUCCH length is 2, and the configured frequency domain is The number of resource blocks is 2 PRBs, and the minimum interval of cyclic shift is 2. The parameters corresponding to other indexes are not enumerated one by one.

Further, in the above embodiment of the present disclosure, step 22 includes:

When a specific PUCCH (ie, the first PUCCH resource) is mapped according to the start index or the minimum index of the CCE, if the first PUCCH resource conflicts with other users (for example, occupied by other users), this is a PUCCH that can be carried by the PDCCH. The resource indication field is used to map another resource; or the same PUCCH resource cannot be used between users of different beam beams. In this case, the PUCCH resource indication field carried by the PDCCH is also required to map another resource; that is, step 22 includes:

And indicating, by the PDCCH, a PUCCH resource indication field, where the PUCCH resource indication field is an information field of the downlink control information DCI, to the terminal, so that the terminal can be based on the index of the first PUCCH resource. The offset value determines an index of the second PUCCH resource in the target PUCCH resource set, where a mapping relationship exists between the index of the second PUCCH resource and the configuration parameter of the second PUCCH resource. Optionally, the index of the second PUCCH resource is equal to the index ±offset value of the first PUCCH resource.

Optionally, if the network side is configured with the resource offset value of the PUCCH, the mapping relationship between the start index or the minimum index of the control channel unit CCE and the index of the first PUCCH resource is:

a resource offset value of the PUCCH indicated for the system information;

It should be noted that the PUCCH resource indication field may be indicated by 2 bits, and the specific offset value may be one of {-1, 0, 1, 2} or {8, 4, 2, 0}.

It should be further noted that the index of the first PUCCH resource or the index of the second PUCCH resource corresponds to at least the following parameters: an index of the physical resource block PRB included in the PUCCH, and an index of the time domain orthogonal mask OCC (for format1), The initial cyclic shift CS value, which is equivalent, the index of the first PUCCH resource or the index of the second PUCCH resource points to a set of the above parameter configuration values, which can determine the specific format and physical resource configuration of the PUCCH resource. Further, the index of the first PUCCH resource or the index of the second PUCCH resource can indicate a specific uplink control channel physical resource.

Alternatively, in the above embodiment of the present disclosure, step 22 includes:

And indicating, by the PDCCH, a PUCCH resource indication field, where the PUCCH resource indication field is an information field of the downlink control information DCI, to the terminal, to target a subset of the target PUCCH resource set; wherein the target PUCCH resource set is Divided into a plurality of subsets; if the PUCCH resource indication field is 2 bits, the target PUCCH resource set is divided into 4 subsets, and the PUCCH resource indication field is used to indicate one of the specific subsets (ie, the target subset).

Specifically, the mapping relationship between the start index or the minimum index of the control channel unit CCE and the index of the third PUCCH resource is:

Or, n _PUCCH3 = n _CCE mod N;

Specifically, when the number of PUCCH resources in a target subset is small, the following formula can be used:

The main purpose of mapping is to improve resource utilization and prevent resource conflicts.

Otherwise, when the number of PUCCH resources in a target subset is large or the CCE aggregation level of the user changes greatly, the following formula can be used:

n _PUCCH3 = n _CCE mod N.

For example, when the aggregation levels L=2 and N=2, if the formula: n _PUCCH3 = n _CCE mod N is used, CCE index=0 and CCE index=2 are mapped to the same PUCCH resource, causing resource conflicts.

In summary, the foregoing embodiment of the present disclosure first uses system information to indicate resource configuration parameters of a target PUCCH resource set, and the terminal can determine a target PUCCH resource set according to the resource configuration parameter; and then use the PDCCH to indicate the target PUCCH resource set. For one PUCCH resource, the terminal can use one PUCCH resource indicated by the PDCCH to transmit the uplink acknowledgement ACK/non-acknowledgement NACK feedback of the downlink information in the random access procedure; some embodiments of the present disclosure can simply and explicitly indicate the allocation of the PUCCH resource, and improve the resource. The flexibility of allocation and the signaling overhead of resource allocation.

As shown in FIG. 3, some embodiments of the present disclosure also provide a resource determining method, including steps 31-32.

Step 31: Receive system information, and determine a target PUCCH resource set according to a resource configuration parameter of a target uplink control channel PUCCH resource set indicated by the system information, where the target PUCCH resource set may be used to transmit downlink information in a random access process. Upstream acknowledgement ACK/non-acknowledgement NACK feedback.

In this step, the resource configuration parameter of the target PUCCH resource set includes: a format type of the PUCCH, a start symbol of the PUCCH, a length of the PUCCH, a frequency domain of the PUCCH, a frequency offset, a resource offset value of the PUCCH, and a cyclic shift. At least two of a minimum interval, a number of frequency domain resource blocks available for PUCCH transmission, and an index of frequency domain resource blocks available for PUCCH transmission.

Step 32: Receive a physical downlink control channel PDCCH, and determine one PUCCH resource in the target PUCCH resource set according to the PDCCH.

The foregoing embodiment of the present disclosure first determines one target PUCCH resource set according to the resource configuration parameter of the target PUCCH resource set indicated by the system information; and then determines one PUCCH resource in the target PUCCH resource set according to the indication of the PDCCH, and the terminal can use the PDCCH indication A PUCCH resource transmits uplink acknowledgement ACK/non-acknowledgement NACK feedback of downlink information in a random access procedure.

Optionally, in the foregoing embodiment of the present disclosure, the system information carries a resource configuration parameter of the target PUCCH resource set; or

Further, in the foregoing embodiment of the present disclosure, when the resource information of the target PUCCH resource set is carried in the system information, each parameter in the resource configuration parameter uses a different bit field indication. That is, different bit fields (also referred to as information fields) are used to indicate different parameters. When the resource information of the target PUCCH resource set is carried on the system information, the use of the 4-bit information field of the system information is as shown in Table 1.

When the index of the preset bit field of the system information is used to indicate the resource configuration parameter of the target PUCCH resource set, since the preset bit field is 4 bits, the preset bit field of the system information has at most 16 different types. Index, if the PUCCH length is 2 characters, the frequency hopping is always on; or if the switch supporting the frequency hopping is needed, it can be realized by reducing the number of minimum intervals of the cyclic shift, for example, setting the minimum of the cyclic shift The interval is 2 or 3.
