Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This invention claims priority to a Chinese patent application filed with the China Patent Office on March 19, 2021, bearing application number 202110297096.2 and titled "Method for determining physical uplink control channel resources, terminal and network side equipment", the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of wireless communication, and in particular to a method for determining physical uplink control channel resources, a terminal, and a network side device. [Background technology]

[0003] Before a Radio Resource Control (RRC) connection is established, the base station cannot configure a Physical Uplink Control Channel (PUCCH) resource set for a User Equipment (UE, also called a terminal) through higher layer RRC signaling, so a method of predefining a PUCCH resource set by a protocol is adopted. At the same time, before an RRC connection is established, the UE's demand for PUCCH is only used to feed back response information of the signaling for establishing an RRC connection. Therefore, the PUCCH resource in the predefined PUCCH resource set only needs to carry 1-2 bits of response information, that is, the PUCCH resource in the predefined PUCCH resource set is only composed of PUCCH format 0 and format 1.

[0004] When a UE accesses the system, the base station can configure one common PUCCH resource set for the UE before all RRC connections are established through system information (System information block type 1, SIB1), which is one of a plurality of predefined sets of PUCCH resource sets, and which is cell-specific, and the UE in the cell determines its PUCCH resource based on this set before the RRC connection is established.

[0024] In the following, the PUCCH resource determination method according to the embodiments of the present application will be described in detail through several embodiments and application scenarios thereof in conjunction with the drawings.

[0025] FIG. 2 shows a flowchart of a method for determining a PUCCH resource according to an embodiment of the present application. As shown in FIG. 2, the method 200 mainly includes the following steps:

[0026] 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 sets of PUCCH resource sets.

[0027] In the embodiment of the present application, a plurality of sets of PUCCH resource sets including only PUCCH format 0 and PUCCH format 1 may be predefined, and each of the predefined plurality of PUCCH resource sets includes a plurality of PUCCH resources, and multi-user multiplexing is performed only by physical resource block (PRB) and cyclic shift. And when interleaving is not supported, the UE turns on the frequency hopping function by default. For example, in Table 1, a plurality of sets of PUCCH resource sets including only PUCCH format 0 and format 1 are predefined. Each of the predefined plurality of PUCCH resource sets includes 16 PUCCH resources.

[0028] [Table 1]

[0029] When a terminal accesses the system, a network side device (e.g., a base station) may indicate the first index in pucch-ResourceCommon in system information (e.g., SIB1) to configure one common PUCCH resource set for the terminal before an RRC connection is established, and this PUCCH resource set may be cell-specific corresponding to a row in Table 1. This PUCCH resource set is a PUCCH resource set before a dedicated PUCCH resource of the terminal is configured, and may be referred to as a common PUCCH resource set.

[0030] S212, the terminal obtains a first target parameter configured for the target PUCCH resource set, where the first target parameter includes one or more elements, and one of the elements indicates a value of the number of physical resource blocks PRB corresponding to the target PUCCH resource set.

[0031] In an embodiment of the present application, one or more elements may be configured for each PUCCH resource set among multiple predefined sets of PUCCH resource sets, each element indicating one candidate value for the number of PRBs in the PUCCH resources in this PUCCH resource set.

[0032] That is, in the embodiment of the present application, each PUCCH resource set of the predefined multiple sets of PUCCH resource sets corresponds to one PRB number value (i.e., one element), and the PRB number is related to the PUCCH format and / or the PUCCH time domain code length. Or, each PUCCH resource set of the predefined multiple sets of PUCCH resource sets may correspond to multiple PRB number values ​​(i.e., multiple said elements).

[0033] In the embodiment of the present application, the value of each of the elements may be obtained by scaling according to the subcarrier spacing (SCS). For example, if the value of one element configured with a 120 kHz SCS is 16, this element is scaled to 4 and 2 for the SCS of 480 kHz and 960 Khz.

[0034] In one possible implementation manner, the terminal may obtain the first target parameter from system information, that is, in this possible implementation manner, the network side device may convey 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 the system information.

[0035] In one possible implementation manner, the first target parameter is a predefined configuration parameter of a target PUCCH resource set, i.e., a definition of the number of PRBs may be added to the predefined sets of PUCCH resource sets. For example, the predefined sets of PUCCH resource sets may be defined in the manner shown in Table 2, and each set of PUCCH resource sets includes a new predefined configuration parameter, i.e., a PRB number set, which may include one or more of the above elements, and the value of each element represents one possible value of the number of PRBs included in the PUCCH resources in the set of PUCCH resource sets.

[0036] [Table 2]

[0037] S214, the terminal determines, according to the first target parameter and pre-defined configuration parameters of the target PUCCH resource set, a target PUCCH resource before radio resource control is established.

[0038] In a specific application, determining a target PUCCH resource is determining a PRB included in the target PUCCH resource, so 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 manner, S214 may include: the terminal determines the number of PRBs included in the target PUCCH resource based on the first target parameter; and the terminal determines a PRB start index of the target PUCCH resource based on the first target parameter and a pre-defined configuration parameter of the target PUCCH resource set.

[0039] In practical application, determining the target PUCCH resource may include determining the number of PRBs included in the target PUCCH resource and the PRB starting index, as well as determining the cyclic shift of the target PUCCH resource.

[0040] If the terminal does not support interleaving, the terminal turns on the frequency hopping function by default, so that the PRB start index includes the PRB start index of the first hop and the PRB start index of the second hop.

[0041] In one possible implementation, the PRB start index of the first hop is independent of the bandwidth of an initial uplink bandwidth part (BWP) where the terminal is located, and is related to the number of PRBs included in the target PUCCH resource. Therefore, in this possible implementation, the terminal determining the PRB start index of the target PUCCH resource based on the first target parameter and the predefined configuration parameters of the target PUCCH resource set may include, when the first target parameter includes one element, the terminal determining the PRB start index of the first hop in the target PUCCH resource based on a third target parameter, and determining the PRB start index of the second hop in the target PUCCH resource based on a fourth target parameter, where the third target parameter is a BWP PRB offset of the target PUCCH resource set.

[0042] In the above possible implementation, the second index r PUCCH may be used to determine the target PUCCH resource, where 0≦r PUCCH ≦15,

[0043] Or, in another possible implementation manner of an embodiment of the present application, the PRB start 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 included in the target PUCCH resource, and the terminal determining the PRB start index of the target PUCCH resource based on the first target parameter and the pre-defined configuration parameters of the target PUCCH resource set may include, when the first target parameter includes one element, the terminal determining the PRB start index of the first hop in the target PUCCH resource based on a fourth target parameter, and determining the PRB start index of the second hop in the target PUCCH resource based on a third target parameter.

[0046] For example, the predefined configuration parameters of each PUCCH resource set of the predefined sets of PUCCH resource sets are 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 a configuration parameter indicating the number of PRBs corresponding to the PUCCH resource set is added to Table 1, where the configuration parameter of the target PUCCH resource set is only one and has a value of 4. Then, by calculating according to the above description, different r PUCCH The target PUCCH resource corresponding to

number

[0047] [Table 3]

[0048] Here, the index of the cyclic shift (CS) of the target PUCCH resource in the cyclic shift set is r PUCCH mod N CS It is.

[0049] On the other hand, if the first target parameter includes multiple elements, i.e., a set of target PUCCH resource sets corresponds to multiple candidate values, and each candidate value indicates the number of one PRB, the terminal needs to determine the number of PRBs included in the target PUCCH resource based on the first target parameter. In one possible implementation manner, determining the number of PRBs included in the target PUCCH resource based on the first target parameter may include the terminal determining a target element from the multiple elements based on a second target parameter, where the second target parameter includes a second index, an SCS of an initial uplink BWP in which the terminal is located, the number of elements in a cyclic shift set of the target PUCCH resource set, and the number of the multiple elements, the second index being an index of the target PUCCH resource in the target PUCCH resource set, and determining that the number of PRBs included in the target PUCCH resource is equal to a value indicated by the target element.

[0050] where the second index is the second index r PUCCH and can be specifically determined by the above method, which will not be described further here.

[0051] In one possible implementation, different sets of PRB numbers may be configured according to different SCSs, that is, the elements included in the first target parameter may be divided into multiple sets, and different SCSs configure different sets, so that the set corresponding to the target PUCCH resource may be determined according to the SCS of the initial uplink BWP where the terminal is located. Of course, the SCSs may not be distinguished, and all SCSs may use the same set.

[0052] For example, taking the predefined multiple sets of PUCCH resource sets shown in Table 2 as an example, if the system information (e.g., SIB1) indicates that the row index of the target PUCCH resource set in Table 2 is 0, the index of the target element (i.e., the target value of the PRB number) corresponding to the target PUCCH resource in the PRB number set in Table 2 is:

number

[0053] In one possible implementation manner, when the PRB start index of the first 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 included in the target PUCCH resource, the terminal determining the PRB start index of the target PUCCH resource based on the first target parameter and the pre-defined configuration parameters of the target PUCCH resource set may include, when the first target parameter includes multiple elements, the terminal determining the PRB start index of the first hop in the target PUCCH resource based on a fifth target parameter and determining the PRB start index of the second hop in the target PUCCH resource based on a sixth target parameter.

[0054] Wherein, the fifth target parameter is a BWP resource block offset of the target PUCCH resource set.

number

number

[0055] Or, in another possible implementation manner, when the PRB start 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 included in the target PUCCH resource, the terminal determining the PRB start index of the target PUCCH resource based on the first target parameter and the pre-defined configuration parameters of the target PUCCH resource set may include, when the first target parameter includes multiple elements, the terminal determining the PRB start index of the first hop in the target PUCCH resource based on a sixth target parameter and determining the PRB start index of the second hop in the target PUCCH resource based on a fifth target parameter.

[0058] Here, the variable in the summation formula is the index, and the PRB number-index Each corresponds to the index-th element in the PRB number set.

number

[0059] For example, taking the predefined multiple sets of PUCCH resource sets shown in Table 2 as an example, if the system information (e.g., SIB1) indicates that the row index of the target PUCCH resource set in Table 2 is 0, calculate according to the above description to obtain different r PUCCH The target PUCCH resources corresponding to

number

[0060] [Table 4]

[0061] Here, the index in the cyclic shift set of the cyclic shift CS of the target PUCCH resource is r PUCCH mod N CS It is.

[0062] In one possible implementation manner of the embodiment of the present application, the first target parameter may further include indication information for indicating a time domain resource, that is, in the embodiment of the present application, the PRBs of the target PUCCH resource may be distributed on different time domain resources.

[0063] In one possible implementation, the terminal obtaining a 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 sets of PUCCH resource sets are predefined, one predefined configuration parameter indicating a time domain resource may be added to each set of PUCCH resource sets.

[0064] In one possible implementation, the indication information indicates a plurality of time domain positions and / or a plurality of time domain Orthogonal Cover Codes (OCCs).

[0065] In one possible implementation manner, determining a target physical uplink control channel (PUCCH) resource before radio resource control is established may further include the terminal determining a time domain location from the multiple time domain locations based on a second index, and determining a time domain resource of the target PUCCH resource according to the determined time domain location, where the second index is an index of the target PUCCH resource in the target PUCCH resource set.

[0066] where the second index is the second index r PUCCH For the specific determination method, please refer to the above description and will not be described further here.

[0067] For example, when configuring multiple candidate combinations of Start Length Indicator Values ​​(SLIVs) for time domain resources of each set of PUCCH resource sets, r PUCCH The time domain resource of the target PUCCH resource may be indicated by:

[0068] For example, the first symbol and the number of symbols in Table 1 are combined into a SLIV candidate combination, and each candidate combination includes two parameters, the position of the first symbol and the number of symbols. A set of PUCCH resource sets may correspond to multiple sets of SLIV candidate combinations, and r PUCCH A candidate combination of target PUCCH resources can be obtained by: For example, if two SLIV candidate combinations (12,2) and (10,2) are included,

number

number

[0069] For example, the row index of the target PUCCH resource set indicated by the system information is 0, and the value of the one element included in the first target parameter is 4, but some configuration parameters of the target PUCCH resource set with row index 0 are shown in Table 5. Then, according to the above method, different r PUCCH The corresponding target PUCCH resource is obtained, as shown in Table 6.

[0070] [Table 5]

[0071] [Table 6]

[0072] Or, in another possible implementation manner, the indication information indicates multiple time-domain orthogonal codes (OCCs), i.e., configure a time-domain OCC set for the time-domain resources of each set of PUCCH resource sets, for example, add one predefined configuration parameter, i.e., OCC index, for each set of PUCCH resource sets in Table 7.

[0073] [Table 7]

[0074] In one possible implementation manner, determining the target PUCCH resource before radio resource control is established may further include the terminal determining one time domain orthogonal code from the multiple time domain orthogonal codes based on a second index, and determining a time domain resource of the target PUCCH resource according to the determined time domain orthogonal code.

[0075] For example, if there are two time domain orthogonal codes in Table 7,

number

number

[0076] For example, if the pre-defined sets 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.

[0077] [Table 8]

[0078] [Table 9]

[0079] In one possible implementation manner, before determining the time domain resource of the target PUCCH resource, the method further includes one of the following:

[0080] (1) The terminal determines according to the indication of the system information that the time domain resource of the target PUCCH resource needs to be determined according to the indication of the indication information. That is, the network side device instructs the terminal that the time domain resource of the target PUCCH resource needs to be determined according to the indication information of the time domain resource, so that the network side device and the terminal can have the same understanding.

[0081] (2) According to the bandwidth and SCS of the initial uplink BWP where the terminal is located, determine that it needs to determine the time domain resource of the target PUCCH resource according to the indication of the indication information.

[0082] For example, the terminal may first obtain the total number of PRBs included in the uplink BWP according to the bandwidth of the initial uplink BWP and the SCS. In a specific application, the radio frequency transmission power cannot exceed the maximum equivalent isotropically radiated power (EIRP), but the radio frequency transmission power can be obtained according to the spectral power density (PSD) and the bandwidth occupied by the PUCCH, where different regions have different regulations for the PSD and the maximum EIRP, and according to the regulatory requirements of the EIRP and PSD of different regions, if the PUCCH resource can be obtained and the maximum EIRP transmission power needs to be reached, the required number of PRBs is as shown in Table 10.

[0083] [Table 10]

[0084] Then, according to the number of PRBs required for each PUCCH resource and the total number of PRBs, the terminal determines that if the time domain resource of the target PUCCH resource is not determined according to the indication of the indication information, the PRB resources of different PUCCH resources cannot meet orthogonality, and determines that the time domain resource of the target PUCCH resource needs to be determined according to the indication of the indication information.For example, in Table 10, for PUCCH resource resource sets with row indexes of 0, 3, 7, and 10 in Table 1, the PRB needs to occupy 8 PRBs, and if it is necessary to ensure the PRB resource orthogonality between different cells, for example, for EIRP=40dBm, PSD=23MHz / dBm, and SCS=480kHz, at least 72 PRBs are required, which exceeds the size of the BWP bandwidth.Therefore, the terminal determines that the time domain resource of the target PUCCH resource needs to be determined according to the indication of the indication information.

[0085] (3) When the bandwidth of the initial uplink BWP is smaller than a threshold bandwidth and / or the SCS is larger than a threshold, it is determined that the time domain resource of the target PUCCH resource needs to be determined based on the indication of the indication information. That is, when the bandwidth of the initial uplink BWP where the terminal is located is smaller than a threshold bandwidth, it is necessary to use multiple time domain locations, and the time domain resource of the target PUCCH resource may be determined based on the indication information of the time domain resource. Or, when the SCS of the initial uplink BWP where the terminal is located is larger than a threshold, it is necessary to use multiple time domain locations, and the time domain resource of the target PUCCH resource may be determined based on the indication information of the time domain resource.
