Description

Technical Field

[0001] The present application belongs to the field of wireless communication technology, and specifically relates to a method for determining physical uplink control channel resources, a terminal, and a network-side device. Background Art

[0002] Before a Radio Resource Control (RRC) connection is established, the base station cannot configure physical uplink control channel (PUCCH) resource sets for user equipment (UE, also known as a terminal) through high-level RRC signaling. Therefore, a protocol-predefined PUCCH resource set is used. At the same time, before the RRC connection is established, the UE's demand for PUCCH is only for feedback of the response information for the signaling establishing the RRC connection. Therefore, the PUCCH resources in the predefined PUCCH resource set only need to carry 1-2 bits of response information, that is, the PUCCH resources in the predefined PUCCH resource set only consist of PUCCH format 0 and format 1.

[0003] When a UE accesses the system, the base station can configure a common PUCCH resource set for all UEs before RRC connection establishment through system information (SIB1). This set is one of multiple predefined PUCCH resource sets. This set is cell-specific. Before RRC connection is established, the UE in the cell determines its PUCCH resource based on this set.

[0030] The following describes in detail the PUCCH resource determination scheme provided in the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0031] Figure 2 A flow chart showing a method for determining PUCCH resources provided by an embodiment of the present application is shown as follows: Figure 2 As shown, the method 200 mainly includes the following steps.

[0032] S210: The terminal receives system information, where the system information includes a first index, and the first index is used to indicate a target PUCCH resource set among a plurality of predefined PUCCH resource sets.

[0033] In an embodiment of the present application, multiple groups of PUCCH resource sets containing only PUCCH format 0 and PUCCH format 1 can be predefined, and each group of PUCCH resource sets in the predefined multiple groups of PUCCH resource sets contains multiple PUCCH resources, and multi-user multiplexing is performed only through physical resource blocks (PRBs) and cyclic shifts. In addition, when interlace is not supported, the UE turns on the frequency hopping function by default. For example, multiple groups of PUCCH resource sets containing only PUCCH format 0 and format 1 are predefined in Table 1. Each group of PUCCH resource sets in the predefined multiple groups of PUCCH resource sets contains 16 PUCCH resources.

[0034] Table 1.

[0035]

[0036] When the terminal accesses the system, the network-side device (e.g., base station) may indicate the first index in the pucch-ResourceCommon field of the system information (e.g., SIB1) to configure a common PUCCH resource set for the terminal before the RRC connection is established. The PUCCH resource set may be cell-specific, corresponding to a row in Table 1. The PUCCH resource set is the PUCCH resource set before the dedicated PUCCH resource of the terminal is configured, and may be referred to as a common PUCCH resource set.

[0037] S212, the terminal obtains a first target parameter configured for the target PUCCH resource set, wherein the first target parameter includes: one or more elements, one of the elements indicating a value of the number of physical resource blocks PRBs corresponding to the target PUCCH resource set.

[0038] In an embodiment of the present application, one or more elements may be configured for each of the predefined multiple PUCCH resource sets, and each element indicates a candidate value for the number of PRBs in the PUCCH resources in the PUCCH resource set.

[0039] That is, in the embodiment of the present application, each of the predefined multiple PUCCH resource sets corresponds to a value of one PRB number (i.e., one element), and the PRB number is related to the PUCCH format and / or the time-domain symbol length of the PUCCH. Alternatively, each of the predefined multiple PUCCH resource sets may correspond to multiple PRB number values ​​(i.e., multiple elements).

[0040] In the embodiment of the present application, the value of each element can be obtained by scaling according to the subcarrier spacing (SCS). For example, if the value of one element configured for a 120kHz SCS is 16, then the value of the element is scaled to 4 and 2 for 480kHz and 960kHz SCSs.

[0041] In one possible implementation, the terminal may obtain the first target parameter from system information. That is, in this possible implementation, the network-side device may carry the number of PRBs corresponding to the target PUCCH resource set corresponding to the first index (i.e., the number of PRBs included in the PUCCH resources in the target PUCCH resource set) through system information.

[0042] In one possible implementation, the first target parameter may also be used as a predefined configuration parameter of the target PUCCH resource set, that is, a definition of the number of PRBs may be added to the predefined multiple groups of PUCCH resource sets. For example, the predefined multiple groups of PUCCH resource sets may be defined in the manner shown in Table 2, where each group of PUCCH resource sets includes a new predefined configuration parameter: a PRB number set, which may include one or more elements, and the value of each element represents a possible value of the number of PRBs included in the PUCCH resources in the group of PUCCH resource sets.

[0043] Table 2.

[0044]

[0045] S214: The terminal determines a target PUCCH resource before radio resource control is established according to the first target parameter and a predefined configuration parameter of the target PUCCH resource set.

[0046] In a specific application, determining the target PUCCH resource is to determine the PRBs included in the target PUCCH resource. Therefore, the target PUCCH resource can be determined by determining the number of PRBs included in the target PUCCH resource and the PRB start index of the target PUCCH resource. Therefore, in one possible implementation, S214 may include: the terminal determining the number of PRBs included in the target PUCCH resource based on the first target parameter; and the terminal determining the PRB start index of the target PUCCH resource based on the first target parameter and a predefined configuration parameter of the target PUCCH resource set.

[0047] In practical applications, in addition to determining the number of PRBs included in the target PUCCH resource and the PRB start index, the cyclic shift of the target PUCCH resource may also be determined.

[0048] In the case of not supporting interlace, the terminal turns on the frequency hopping function by default. Therefore, the PRB start index includes the PRB start index of the first hop and the PRB start index of the second hop.

[0049] In one possible implementation, the PRB start index of the first hop is independent of the bandwidth of the initial uplink BWP where the terminal is located, but is related to the number of PRBs contained in the target PUCCH resource. Therefore, in this possible implementation, the terminal determines the PRB start index of the target PUCCH resource according to the first target parameter and the predefined configuration parameters of the target PUCCH resource set, which may include: when the first target parameter includes one element, the terminal determines the PRB start index of the first hop in the target PUCCH resource according to the third target parameter, and determines the PRB start index of the second hop in the target PUCCH resource according to the fourth target parameter; wherein the third target parameter includes: the BWP PRB offset of the target PUCCH resource set (For example, in Tables 1 and 2 It indicates the offset of the PRB where the target PUCCH resource in the target PUCCH resource set is located compared to the minimum PRB index of the BWP where the terminal is located), the second index, the number of elements in the cyclic shift set of the target PUCCH resource set (that is, the cyclic shift set in Table 1 and Table 2), and the elements included in the first target parameter, the second index is the index of the target PUCCH resource in the target PUCCH resource set; the fourth target parameter includes: the bandwidth of the initial uplink BWP where the terminal is located, the BWP resource block offset of the target PUCCH resource set The second index, the number of elements in the cyclic shift set of the target PUCCH resource set, and the elements included in the first target parameter.

[0050] In the above possible implementation, the second index r PUCCH Can be used to determine the target PUCCH resource, 0≤r PUCCH ≤15, Among them, Δ PRI N is the PUCCH resource index indication field in the downlink control information (DCI) received by the UE. CCEThe number of control channel elements (CCEs) in the control resource set (CORESET) of the physical downlink control channel (PDCCH) where the DCI received by the UE is located, n CCE,0 The first CCE index of PDCCH.

[0051] Alternatively, in another possible implementation of an embodiment of the present application, the PRB starting index of the second hop is independent of the bandwidth of the initial uplink BWP in which the terminal is located, and is related to the number of PRBs contained in the target PUCCH resource. The terminal determines the PRB starting index of the target PUCCH resource based on the first target parameter and the predefined configuration parameters of the target PUCCH resource set, which may include: when the first target parameter includes one element, the terminal determines the PRB starting index of the first hop in the target PUCCH resource based on the fourth target parameter, and determines the PRB starting index of the second hop in the target PUCCH resource based on the third target parameter.

[0052] For example, if The UE determines the PRB index of the first hop as The PRB index of the second hop is The target PUCCH resource set For example, the target PUCCH resource set corresponding to Table 1 or Table 2 N CS is the total number of cyclic shift sequences in the cyclic shift sequence set corresponding to the target PUCCH resource set, that is, the total number of cyclic shift sequences in the cyclic shift sequence set in the last column of a row corresponding to the target PUCCH resource set in Table 1 or Table 2, is the bandwidth of the initial uplink BWP where the terminal is located, PRB number The number of PRBs included in the target PUCCH resource, that is, the value of the one element in the first target parameter.

[0053] And if The UE determines the PRB index of the first hop as The PRB index of the second hop is N CSis the total number of cyclic shift sequences in the cyclic shift sequence set corresponding to the target PUCCH resource set, that is, the total number of cyclic shift sequences in the cyclic shift sequence set in the last column of a row corresponding to the target PUCCH resource set in Table 1 or Table 2.

[0054] For example, assuming that the predefined configuration parameters of each of the predefined multiple PUCCH resource sets are as shown in Table 1, the system information indicates that the row index (i.e., the first index) of the target PUCCH resource set in Table 1 is 0, and the value of the one element in the first target parameter included in the received system information is 4, that is, the number of PRBs included in the target PUCCH resource is 4, or there may be an additional configuration parameter in Table 1 indicating the number of PRBs corresponding to the PUCCH resource set, wherein there is only one configuration parameter for the target PUCCH resource set, and the value is 4. Then, according to the above description, calculations are performed to obtain different r PUCCH The corresponding target PUCCH resources are shown in Table 3.

[0055] Table 3.

[0056]

[0057] The index of the cyclic shift CS of the target PUCCH resource in the cyclic shift set is r PUCCH mod N CS .

[0058] If the first target parameter includes multiple elements, that is, a set of target PUCCH resource sets corresponds to multiple candidate values, and each candidate value indicates the number of PRBs, then the terminal needs to determine the number of PRBs contained in the target PUCCH resources based on the first target parameter. In one possible implementation, determining the number of PRBs contained in the target PUCCH resources based on the first target parameter may include: the terminal determining the target element from the multiple elements based on a second target parameter, wherein the second target parameter includes: a second index, the SCS of the initial uplink BWP where the terminal is located, the number of elements in the cyclic shift set of the target PUCCH resource set, and the number of the multiple elements, and the second index is the index of the target PUCCH resource in the target PUCCH resource set; determining that the number of PRBs contained in the target PUCCH resource is equal to the value indicated by the target element.

[0059] Among them, the second index is the second index r mentioned above PUCCH , which can be determined by the above method, will not be described here.

[0060] In one possible implementation, different sets of PRB numbers can be configured according to different SCSs. That is, the multiple elements included in the first target parameter can be divided into multiple sets, and different SCSs configure different sets. Therefore, the set corresponding to the target PUCCH resource can be determined according to the SCS of the initial uplink BWP in which the terminal is located. Of course, it is also possible not to distinguish between SCSs, and all SCSs use the same set.

[0061] For example, taking the predefined multiple groups of PUCCH resource sets shown in Table 2 as an example, when the system information (e.g., SIB1) indicates that the row index of the target PUCCH resource set in Table 2 is 0, the target element corresponding to the target PUCCH resource (i.e., the target value of the number of PRBs) in the PRB number set in Table 2 is indexed as follows:

[0062]

[0063] Among them, N PRB It is the number of elements included in the PRB number set of the target PUCCH resource set, for example, the number of elements included in the first target parameter.

[0064] In one possible implementation, the PRB starting index of the first hop is independent of the bandwidth of the initial uplink BWP where the terminal is located, but is related to the number of PRBs contained in the target PUCCH resource. The terminal determines the PRB starting index of the target PUCCH resource based on the first target parameter and the predefined configuration parameters of the target PUCCH resource set, which may include: when the first target parameter includes multiple elements, the terminal determines the PRB starting index of the first hop in the target PUCCH resource based on the fifth target parameter, and determines the PRB starting index of the second hop in the target PUCCH resource based on the sixth target parameter.

[0065] The fifth target parameter includes: the BWP resource block offset of the target PUCCH resource set a second index, the number of elements in a cyclic shift set of the target PUCCH resource set, and each element included in the first target parameter, wherein the second index is an index of the target PUCCH resource in the target PUCCH resource set;

[0066] The sixth target parameter includes: the bandwidth of the initial uplink BWP where the terminal is located, the BWP resource block offset of the target PUCCH resource set The second index, the number of elements in the cyclic shift set of the target PUCCH resource set, and each element included in the first target parameter.

[0067] Alternatively, in another possible implementation, the PRB starting index of the second hop is independent of the bandwidth of the initial uplink BWP in which the terminal is located, but is related to the number of PRBs contained in the target PUCCH resource. The terminal determines the PRB starting index of the target PUCCH resource based on the first target parameter and the predefined configuration parameters of the target PUCCH resource set, which may include: when the first target parameter includes multiple elements, the terminal determines the PRB starting index of the first hop in the target PUCCH resource based on the sixth target parameter, and determines the PRB starting index of the second hop in the target PUCCH resource based on the fifth target parameter.

[0068] For example, if The UE determines the PRB index of the first hop as The PRB index of the second hop is NCS is the total number of cyclic shift sequences in the cyclic shift sequence set in the last column of the table.

[0069] if The UE determines the PRB index of the first hop as The PRB index of the second hop is N CS is the total number of cyclic shift sequences in the cyclic shift sequence set in the last column of the table.

[0070] Among them, the variables in the summation formula are index, PRB number-index They correspond to the index-th element in the PRB number set. It means from The PRB corresponding to the index number-index Accumulate, that is, accumulate the number of PRBs in the set from 0 to The values ​​of each element of .

[0071] For example, taking the predefined multiple PUCCH resource sets shown in Table 2 as an example, when the system information (such as SIB1) indicates that the row index of the target PUCCH resource set in Table 2 is 0, the calculation is performed according to the above description to obtain different r PUCCH The corresponding target PUCCH resources are shown in Table 4.

[0072] Table 4.

[0073]

[0074] The index of the cyclic shift CS of the target PUCCH resource in the cyclic shift set is r PUCCH mod N CS .

[0075] In a possible implementation of the embodiment of the present application, the first target parameter may further include: indication information indicating time domain resources. That is, in the embodiment of the present application, the PRBs of the target PUCCH resources may be distributed on different time domain resources.

[0076] In one possible implementation, the terminal obtaining the first target parameter configured for the target PUCCH resource set may further include: the terminal obtaining the indication information from a predefined configuration parameter of the target PUCCH resource set. That is, in this possible implementation, when multiple groups of PUCCH resource sets are predefined, a predefined configuration parameter indicating a time domain resource may be added for each group of PUCCH resource sets.

[0077] In a possible implementation manner, the indication information indicates multiple time domain positions and / or multiple time domain orthogonal codes (OCCs).

[0078] In one possible implementation, determining the target physical uplink control channel PUCCH resource before wireless resource control is established may also include: the terminal determines a time domain position from the multiple time domain positions based on a second index, and determines the time domain resource of the target PUCCH resource according to the determined time domain position, wherein the second index is the index of the target PUCCH resource in the target PUCCH resource set.

[0079] Among them, the second index is the second index r mentioned above PUCCH The specific determination method can be found in the above description and will not be repeated here.

[0080] For example, multiple candidate combinations of start length indicator values ​​(SLIV) are configured for the time domain resources of each group of PUCCH resource sets, which can be obtained by r PUCCH Indicates the time domain resource of the target PUCCH resource.

[0081] For example, the first symbol and the number of symbols in Table 1 are combined into candidate combinations of SLIV, and each candidate combination includes two parameters: the position of the first symbol and the number of symbols. A set of PUCCH resource sets can correspond to multiple sets of candidate combinations of SLIV, through r PUCCH The candidate combination of the target PUCCH resource can be obtained. For example, if the candidate combination of two SLIVs (12, 2) and (10, 2) is included, then if Then SLIV_index=0, that is, the time domain resource of the target PUCCH resource is the first SLIV candidate combination (12, 2); if Then SLIV index=1, that is, the time domain resource of the target PUCCH resource is the second SLIV candidate combination (10, 2).

[0082] For example, assuming that the row index of the target PUCCH resource set indicated by the system information is 0, the value of the one element included in the first target parameter is 4, and some configuration parameters of the target PUCCH resource set with row index 0 are shown in Table 5, then different r PUCCH The corresponding target PUCCH resources are shown in Table 6.

[0083] Table 5.

[0084]

[0085] Table 6.

[0086]

[0087] Alternatively, in another possible implementation, the indication information indicates multiple time-domain orthogonal codes (OCCs). That is, a time-domain OCC set is configured for the time-domain resources of each PUCCH resource set. For example, in Table 7, a predefined configuration parameter is added for each PUCCH resource set: the OCC index.

[0088] Table 7.

[0089]

[0090] In one possible implementation, determining the target PUCCH resource before wireless resource control is established may also include: the terminal determines a time domain orthogonal code from the multiple time domain orthogonal codes based on the second index, and determines the time domain resource of the target PUCCH resource according to the determined time domain orthogonal code.

[0091] For example, in Table 7, there are 2 time domain orthogonal codes. If occ_index=0, that is, the target PUCCH resource corresponds to the first time domain orthogonal code, and if occ_index=1, that is, the target PUCCH resource corresponds to the second time domain orthogonal code.

[0092] For example, if the predefined multiple groups of PUCCH resource sets adopt the configuration parameters shown in Table 8, the target PUCCH resources obtained according to the above solution are shown in Table 9.

[0093] Table 8.

[0094]

[0095] Table 9.

[0096]

[0097]

[0098] In one possible implementation, before determining the time domain resource of the target PUCCH resource, the method further includes one of the following:

[0099] (1) The terminal determines, based on the indication of the system information, that it needs to determine the time domain resource of the target PUCCH resource based on the indication of the indication information. In other words, the network-side device instructs the terminal to determine the time domain resource of the target PUCCH resource based on the indication of the time domain resource, so that the network-side device and the terminal have the same understanding.

[0100] (2) The terminal determines the time domain resource of the target PUCCH resource according to the bandwidth of its initial uplink BWP and SCS and the indication of the indication information.

[0101] For example, the terminal may first obtain the total number of PRBs included in the uplink BWP based on the bandwidth of the initial uplink BWP and the SCS. In specific applications, the RF transmit power cannot exceed the maximum equivalent isotropically radiated power density (EIRP), and the RF transmit power can be obtained by the spectral power density (PSD) and the bandwidth occupied by the PUCCH. Different regions have different regulations on PSD and maximum EIRP. Based on the regulatory requirements of EIRP and PSD in different regions, the PUCCH resources can be obtained. If the maximum EIRP transmit power is required, the required number of PRBs is shown in Table 10.

[0102] Table 10.

[0103]

[0104] Then, based on the number of PRBs required for each PUCCH resource and the total number of PRBs, it is determined that if the time domain resources of the target PUCCH resources are not determined according to the indication of the indication information, the PRB resources of different PUCCH resources cannot meet the orthogonality, and it is determined that the time domain resources of the target PUCCH resources need to be determined according to the indication of the indication information. For example, in Table 10, for the PUCCH resource set with row indexes 0, 3, 7, and 10 in Table 1, the PRB needs to occupy 8 PRBs. If it is necessary to ensure the orthogonality of PRB resources between different cells, for example, for EIRP = 40 dBm, PSD = 23 MHz / dBm, SCS = 480 kHz, at least 72 PRBs are required, which exceeds the BWP bandwidth size. Therefore, the terminal determines that it needs to determine the time domain resources of the target PUCCH resources according to the indication of the indication information.

[0105] (3) When the bandwidth of the initial uplink BWP is less than the threshold bandwidth and / or the SCS is greater than the threshold, it is determined that the time domain resource of the target PUCCH resource needs to be determined according to the indication of the indication information. That is, if the bandwidth of the initial uplink BWP where the terminal is located is less than the threshold bandwidth, multiple time domain positions need to be used, and the time domain resource of the target PUCCH resource can be determined according to the indication information of the time domain resource. Alternatively, if the SCS of the initial uplink BWP where the terminal is located is greater than the threshold, multiple time domain positions need to be used, and the time domain resource of the target PUCCH resource can be determined according to the indication information of the time domain resource.

[0106] The technical solution provided by the embodiments of the present application configures a parameter indicating the number of PRBs for a predefined public PUCCH resource set, thereby enabling the determination of target PUCCH resources when PUCCH format 0 and / or PUCCH format 1 support resource allocation for multiple PRBs. Furthermore, a configuration parameter indicating time domain resources is configured for the public PUCCH resource set, thereby ensuring good frequency domain orthogonality of the predefined public PUCCH resources when the BWP bandwidth is insufficient.
