and sending the resource indication information to the terminal.

By the method, resource indication information used for indicating a terminal to determine a Physical Uplink Control Channel (PUCCH) resource is determined, wherein the resource indication information comprises Downlink Control Information (DCI), and the DCI is used for determining a resource index in a PUCCH resource set; the PUCCH resource set is indicated to a terminal through Residual Minimum System Information (RMSI); and sending the resource indication information to the terminal, so that the PUCCH resource set can be indicated through the RMSI, and the DCI can be fully applied to dynamically indicate the resource index in the PUCCH resource set, thereby realizing a more flexible PUCCH resource indication scheme and avoiding resource conflict and waste.

Therefore, information contents such as PUCCH start symbol, index of PUCCH physical resource block PRB, whether to shift based on designated PUCCH start symbol, whether to shift based on designated physical resource block PRB index, and the like can be indicated by DAI information bits.

Optionally, the set of resources indicated by the RMSI is determined at least by the indicated parameter cyclic shift CS interval or minimum cyclic shift interval, and a PRB offset value; wherein the content of the first and second substances,

Detailed Description

In a New Radio (NR) system of 5G, two scenarios after an initial access phase and Radio Resource Control (RRC) connection need to be considered for Resource allocation of a PUCCH. After RRC connection establishment, a two-level indication method of RRC signaling plus dynamic DCI signaling is usually adopted, where RRC signaling is used to indicate one resource set (resource set) and DCI signaling is used to indicate one resource index (resource index) in the resource set. However, in an initial access stage of User Equipment (UE), there is no indication of RRC signaling, and embodiments of the present application provide a method based on a combination indication of system information RMSI and DCI, so as to notify the UE of a PUCCH resource of message 4 in the initial access stage.

In the 5G NR technical system, two PUCCH resource indication methods can be provided, one is an explicit indication method, namely, RRC signaling is firstly used for indicating one allocated resource set of the UE, and then DCI is used for informing the UE of a specific resource index; another method is an implicit resource indication method, that is, an LTE method is used, and the index of the smallest CCE corresponding to the PDCCH is mapped to a specific PUCCH resource. The two methods have advantages and disadvantages respectively, the dominant method is more flexible, and the recessive method can save signaling overhead.

In the PUCCH resource indication of the initial access message 4, the PUCCH resource set may be indicated by the RMSI information, and then one resource index in the resource set may be indicated by combining the DCI and the implicit indication. For example, the PUCCH resource set includes 14 PUCCH resources, and one PUCCH resource in the PUCCH resource set is determined using an implicit indication of 3 bits plus 1 bit. If the minimum CCE index of the PDCCH is used for implicit indication, in order to distinguish 16 PUCCH resources, the CCE indexes of two UEs cannot be the same or the CCE indexes are parity mapped identically, because 3 bits can only distinguish 8 resource subsets, and the CCE index must complete resource indication in the last resource subset. For more flexible resource indication, a fully explicit 4-bit resource indication can be adopted as a more efficient implementation scheme. The embodiment of the application fully applies DCI to complete dynamic indication, and resource conflict and waste are avoided.

The embodiment of the application provides a method for indicating PUCCH parameters or resources by relying on RMSI. An example is given in table 1 below, where the RMSI indicates that the PUCCH sets include 16 PUCCH sets, each row corresponds to a configuration and a corresponding resource set, and each set includes 16 resources. The PUCCH parameters in each set are determined by a corresponding parameter indication in a row, which may include one or a combination of the following: PUCCH format, PUCCH start symbol, PUCCH symbol number (length), PRB offset (offset value), PUCCH minor cyclic shift gap (minimum cyclic shift interval). The minimum cyclic shift interval can be used to determine the number of resources carried by one PRB, because one PRB contains 12 cyclic shifts CS in total, and if the interval is 3, 4 resources can be reused on one PRB.

TABLE 1

The embodiment of the application provides a PUCCH resource indication and determination method, optionally, the method can be used for resource indication in an initial access phase, and the main principle is to indicate a Physical Uplink Control Channel (PUCCH) resource set including 16 PUCCH resources by using RMSI Information, and then indicate a specific resource index in the resource set by using 4-bit Downlink Control Information (DCI) indication Information.

In the technical solution provided in the embodiment of the present application, a single DCI Information field may be used, or a plurality of DCI Information fields may be used to jointly indicate a PUCCH resource index in a resource set determined by Remaining Minimum System Information (RMSI).

In the technical solution provided in the embodiment of the present application, the resource index of the PUCCH may be combined into a final resource index by the PUCCH resource indication field of the DCI and the 1-bit implicit information indication. For example, 1-bit indication information is used to indicate the hopping patterns of the PUCCH, each hopping pattern corresponds to 8 resource indices, and is indicated by a 3-bit DCI. The bit implicit information is indicated by the minimum CCE index of the PDCCH. The recessive information bit can be at the high order of 4 bits, and also can be at the low order of 4 bits; the implicit information may be used for partial information of the PUCCH alone or jointly indicate a PUCCH resource index.

The technical solution provided in the embodiment of the present application further includes an explicit indication method for DCI indication.

For example, 16 PUCCH resources may be indicated using one single 4-bit DCI information field, with DCI bit information and PUCCH resource indices in a one-to-one correspondence; this separate 4-bit information field may be a dedicated PUCCH information indication field or an information field common to other information time domains.

For another example, 16 PUCCH resource indexes may be jointly indicated using a plurality of DCI information fields including a 3-bit PUCCH specific information field and a 1-bit other information field, or a combination of a plurality of other information fields.

Specific examples of several embodiments are given below:

embodiment 1, the lower bits of 2-bit DAI information are used, or the upper 1 bit and special 3 bits are combined into 4-bit PUCCH resource indication information. In the initial access phase, since this information field of Downlink Assignment Index (DAI) is not used for a specific purpose, it can be used for PUCCH resource indication.

Example 2: the 1-bit information of DAI and the special 3-bit are combined into 4-bit PUCCH resource indication information, and the other 1-bit DAI information is used for indicating the starting position of PUCCH. For example, when the time domain length of the PUCCH is 2 symbols, this bit of DAI information is 1 to indicate that the PUCCH start symbol is 10, and DAI information is 0 to indicate the PUCCH start symbol 12.

Another use of the 1 bit (i.e., DAI) is to indicate whether the PUCCH start symbol is the start symbol corresponding to the PUCCH resource indicated by the 4 bits in DCI, or whether to perform a fixed offset based on the start symbol. For example, if the predetermined fixed offset value is 2, when the starting symbol corresponding to one PUCCH resource among the 16 PUCCH resources indicated by the 4 bits is 12, this extra DAI bit may indicate whether to keep the original starting symbol as 12 or offset by 2 symbols, and if the bit information bit is 1, it indicates that there is an offset, the starting symbol is 12-2 — 10, and of course, the offset may be a forward offset or a backward offset, and may be preset according to actual needs.

The 1-bit (i.e., DAI) is used for another purpose of indicating whether the position of a Physical Resource Block (PRB) of a PUCCH is a PRB itself corresponding to a PUCCH Resource indicated by 4 bits in DCI or a fixed offset is performed based on the PRB. For example, the predetermined fixed offset value is 2, if the PRB corresponding to one of the 16 PUCCH resources indicated by the 4 bits is 2, the 1-bit DAI indicates no offset, the PRB is the PRB numbered 2, and if there are 2 RBs fixedly offset, the PRB is the PRB numbered 2-2 ═ 0.

Example 3: using multiple information fields to indicate 16 PUCCH resource indexes, and using the remaining bits of the information fields to indicate the parameter information of the PUCCH, wherein the parameter information comprises one or the combination of the following contents: cyclic shift (cyclic shift), orthogonal mask (cover code OCC) index, PUCCH start symbol, format (format) of PUCCH, and the like.

Further, if the PUCCH resource set indicated by the RMSI includes more than 16 resources, more DCI information bits are required to indicate the PUCCH resource index. For example, when a resource set includes 32 resources, 5 bits are needed, and a 5-bit indication field is formed by a 3-bit PUCCH dedicated information field and 2-bit DAI information bits; if one resource set contains 64 resources, 6 bits are needed, and a 6-bit indication domain is formed by a 3-bit PUCCH special information domain and 3-bit HARQ information bits; harq (hybrid Automatic Repeat request), hybrid Automatic Repeat request, and an indication field for indicating retransmission process information, which is used for indicating PUCCH at this time.

The technical scheme provided by the embodiment of the application comprises a corresponding method of the PUCCH resource index and the OCC index. For example, when the configured minimum cyclic shift CS interval is 2, the format of PUCCH is format 1, and one PRB may be cyclically shifted by 6 {0, 2, 4, 6, 8, 10 }. Different OCCs may be used for different PUCCH lengths, for example, when the number of PUCCH symbols is 10, the OCC length may be 2 or 3 due to frequency hopping, and when the number of symbols is 14, the OCC length may be 4 or 3. The orthogonal sequences are generated as shown in table 2 below.

In the formula

In, N_SFDenotes the OCC spreading length, m denotes the OCC sequence bit index,

representing the phase value. i denotes an OCC orthogonal mask index. In Table 2

Indicating the spreading length.

Assuming that the number of PUCCH symbols is 10, the minimum OCC length used for reference signal and data of PUCCH is 2, as shown in table 2 above, there are two OCC codes, and in order to minimize interference between users, it is necessary to make adjacent CS indexes correspond to different OCCs, for example, {0, 4, 8} corresponds to OCC code 1, and {2, 6, 10} corresponds to OCC code 2, so that OCCs of two adjacent CSs are orthogonal, and interference between users can be maximally suppressed.

In summary, in a network side, for example, in a base station side, referring to fig. 1, a resource indication method provided in an embodiment of the present application includes:

s101, determining resource indication information for indicating a terminal to determine a Physical Uplink Control Channel (PUCCH) resource, wherein the resource indication information comprises Downlink Control Information (DCI), and the DCI is used for determining a resource index in a PUCCH resource set; the PUCCH resource set is indicated to a terminal through Residual Minimum System Information (RMSI);

More specifically, the terminal first obtains a set indication information containing 16 resources according to the RMSI, and then determines the resource index and the frequency hopping information of the PUCCH according to the DCI or the information indicating the CCE index implicitly through the DCI, where the frequency hopping information may also be a part of the resource index, for example, 16 PUCCH resources in total, where 8 PUCCH resources obey frequency hopping pattern 1 and the other 8 PUCCH resources obey frequency hopping pattern 2. PUCCH resource number NP capable of being carried by one PRB^RU^BCCH is determined by minimum cyclic shift interval, when terminal obtains resource index n of PUCCH_PUCCHAfter the information, the terminal may derive a median value of a PRB index according to the following formula:
