Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to an uplink control channel resource configuration method and apparatus. Background Art

[0002] In the field of wireless communication, in the unlicensed spectrum of the 52.6 GHz to 71 GHz frequency band, since using a single RB (Resource Block) resource for the PUCCH (Physical Uplink Control Channel) will result in limited transmission power, it is allowed to occupy physical resources of multiple RBs (Resource Blocks) in the frequency domain. Since the number of RBs may change according to the required transmission power, the base station and the terminal need to signal to notify the number of RBs configured for the PUCCH. The notification method can be a high-layer RRC (Radio Resource Control) signaling, a physical-layer DCI (Downlink Control Information) signaling independent indication, and a physical-layer PRI indication.

[0003] In R17, in the PUCCH PF0 / 1 / 4 (PUCCH Format) enhancement project of 52.6 GHz to 71 GHz, it is supported to obtain greater power under the PSD (Power Spectral Density) limit of the shared spectrum by increasing the number of RBs (N RB ). The minimum number of RBs supported is 1, and the maximum number of RBs is calculated by the PSD limit of the transmitted signal, the EIRP (Equivalent Isotropic Radiated Power) limit, the antenna shaping gain of the UE (User Equipment), and the CM (Cubic Metric) value. Since the number of transmitted RBs of the PUCCH is not a fixed value but a range from 1 to , it is necessary to determine the available values of the number of RBs supported in the system.

[0004] In the prior art, currently, PUCCH PF0 / 1 / 4 is transmitted using 1 RB and does not require configuration of the number of RBs. In the existing solutions during the standard advancement process, the granularity of the number of RBs is 1, that is, the step size is 1, so the RB values are all possible integers. If DCI signaling is used to independently indicate the number of RBs, a relatively large number of bits are required, resulting in a large overhead of control signaling. In addition, since DFT (Discrete Fourier Transform) pre-transformation is required during the symbol processing of PUCCH format 4, PUCCH format 4 also needs to additionally satisfy where α2, α3, α5 are non-negative integers. In the prior art, for PUCCH PF2 / 3, multiple RBs can be used for transmission. The method of resource configuration is to configure the resource set of PUCCH through RRC signaling. The number of RBs corresponding to each resource set is a fixed value, ranging from 1 to 16, and is configured through RRC parameters. If the base station needs to adjust the value range of the number of RBs, it is necessary to re-inform the user of the entire set of RBs, thus increasing the system burden. Summary of the Invention

[0119] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. These three situations. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0120] In the embodiments of the present application, the term "a plurality" refers to two or more, and other quantifiers are similar.

[0121] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0122] Figure 1 is one of the schematic flowcharts of the uplink control channel resource configuration method provided by the embodiments of the present application. As Figure 1 shown, the embodiments of the present application provide an uplink control channel resource configuration method, and its execution subject may be a terminal, such as a mobile phone, etc. The method includes:

[0123] Step 101, receive the configuration information of the uplink control channel resource sent by the network-side device, where the configuration information at least includes the resource start position;

[0124] Specifically, in the embodiments of the present application, the terminal first receives the configuration information of the Physical Uplink Control Channel (PUCCH) resource sent by the network-side device. And the configuration information includes the resource start position, and may also include the first number of Resource Blocks (RBs) occupied by the uplink control channel, the uplink control channel resource identification number, etc. Among them, the resource start position is the start position of the RB resource block. The RB resource block may be a Physical Resource Block (PRB) or a Virtual Resource Block (VRB), which is not limited in the present application.

[0125] Then, the terminal determines the uplink control channel resource required by the terminal according to the received resource start position and in combination with the first number of RBs occupied by the uplink control channel.

[0126] Step 102, receive the Downlink Control Information (DCI) sent by the network-side device, and determine a parameter index based on the DCI. The parameter index is used to determine the first number of RBs occupied by the uplink control channel in a first resource set; where the first resource set includes multiple elements, the parameter index corresponding to each element is the index of each element in the first resource set, and each element corresponds to the number of RBs occupied by the uplink control channel; the multiple elements included in the first resource set are determined based on the value range of the RBs corresponding to the current Subcarrier Spacing (SCS); where the resource start position and the first number of RBs occupied by the uplink control channel are used to determine the uplink control channel resource.

[0127] Specifically, in the embodiments of the present application, the corresponding RB value range is determined according to the current sub - carrier SCS. For example, when the current sub - carrier SCS = 120KHZ, the corresponding RB value range is [1, 8]. Then, the number of elements included in the first resource set is determined through the RB value range. For example, when the current RB value range is [1, 8], the first resource set contains at most 8 elements and at least 1 element. The value of each element represents the number of RBs occupied by the uplink control channel.

[0128] The terminal receives the downlink control information DCI sent by the network - side device, and then determines the parameter index of the number of RBs of the uplink control channel according to the DCI. In the present application, it is simply referred to as the parameter index. Among them, there is a one - to - one relationship between the parameter index and the number of RBs of the uplink control channel. Through this index, the number of RBs of the uplink control channel corresponding to this terminal, that is, the first quantity, can be found. For example, when the value of the number of RBs (nrofPRBs) is 8, its corresponding parameter index index is 7.

[0129] The uplink control channel resource configuration method provided by the embodiments of the present application pre - configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network - side, and determines the matching first resource set in the configuration information through the downlink control information sent by the network - side, and then determines the number of RBs in the uplink control channel that need to be occupied for access. And the first resource set is determined based on the RB value range corresponding to the current sub - carrier SCS.

[0130] Optionally, the configuration method of the first resource set includes any one of the following:

[0131] Method 1: Configure the first resource set based on the RRC signaling, and indicate it in an enumeration manner;

[0132] Method 2: Obtain the first resource set based on the RB value range corresponding to the current sub - carrier spacing SCS and the pre - set calculation rule.

[0133] Specifically, when the configuration method adopts Method 1, the configuration of the first resource set can be directly configured based on the RRC signaling in an enumeration manner.

[0134] There is an implementation scenario. For example, when SCS = 120 kHz, the number of RBs of the PUCCH channel is represented by nrofPRBs. Taking PRB as an example, the corresponding values of the first resource set can be {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32}; the parameter index of the number of PRBs (nrofPRBs) is the index of the elements in the set. For example, when index = 0, it corresponds to nrofPRBs1; when index = 1, it corresponds to nrofPRBs2.

[0135] Another implementation scenario All integers within the range. Among them is the minimum number of RBs configurable for PUCCH under a certain SCS value is the maximum number of RBs configurable for PUCCH under a certain SCS value.

[0136] When the configuration method adopts Method 2, based on the value range of the RBs corresponding to the current subcarrier spacing SCS and the preset calculation rule, the first resource set is obtained.

[0137] There are various values for the current subcarrier spacing SCS, such as 120KHZ, 480KHZ, 960KHZ, etc. According to different SCS values, the corresponding different RB value ranges are determined, and based on the preset calculation rule, the first resource set is further calculated.

[0138] Among them, there are mainly two preset calculation rules: the first calculation formula and the second calculation formula.

[0139] The first calculation formula is:

[0140]

[0141] Among them, nrofPRBs(index) is the element in the first resource set, and index is the parameter index corresponding to each element is the minimum number of RBs configurable for PUCCH under the current subcarrier spacing SCS value is the maximum number of RBs configurable for PUCCH under the current subcarrier spacing SCS value, and N is the number of bits required to indicate the number of PUCCH RBs.

[0142] The second calculation formula is:

[0145] The uplink control channel resource configuration method provided by the embodiments of this application calculates the configurable value of the PUCCH channel resource granularity by directly notifying the enumerated set of the number of RBs of PUCCH, or by setting the calculation formula for the number of RBs of PUCCH and notifying the relevant parameters to determine the set of the number of RBs of PUCCH, and determines the channel RB number of PUCCH through DCI indication, so as to be able to flexibly configure the number of RBs of PUCCH.

[0146] Optionally, the configuration information further includes the parameter index and the channel resource identification number.

[0147] The DCI includes the channel resource identification number, and the determining the parameter index based on the DCI includes:

[0148] Based on the channel resource identification number included in the DCI, obtain the configuration information including the channel resource identification number, and confirm the parameter index and the resource start position therefrom.

[0149] Specifically, the configuration information received by the terminal from the network side device includes: the resource start position startingPRB, the parameter index index, and the channel resource identification number (pucch-ResourceId). This configuration information corresponds to Scheme A.

[0150] Among them, the parameter index index represents the index for determining the number of PUCCH channel RBs (nrofPRBs). When the index is different, the determined nrofPRBs may have discontinuous values.

[0151] A network-side device, such as a base station, indicates the pucch-ResourceId to the terminal UE through the PRI (Physical Resource Indicator) in the scheduling signaling DCI. The terminal UE determines the nrofPRBs and the startingPRB according to the pucch-ResourceId and the configuration information. Furthermore, the PUCCH frequency-domain resource position is determined based on the above parameters.

[0152] Optionally, the number of RBs occupied by the uplink control channel represented by each element in the first resource set indicated in an enumerated manner is a series of discontinuous values.

[0153] After the terminal receives the configuration information corresponding to Scheme A, each element in its first resource set is a discontinuous value, and each element represents the number of RBs occupied by the uplink control channel, thereby realizing the configuration of the uplink control channel resources in discontinuous intervals and enabling flexible configuration of the uplink control channel resources.

[0154] The method for configuring uplink control channel resources provided by the embodiments of the present application pre-configures the uplink control channel resources through the configuration information sent by the network side. When the configuration information includes a parameter index, the number of RBs of the configured PUCCH channel is discontinuous. And the first resource set is determined in the configuration information through the downlink control information sent by the network side, and then the number of RBs that need to be occupied by the uplink control channel for access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS.

[0155] Optionally, the configuration information further includes a channel resource identification number; the DCI includes the channel resource identification number, and the channel resource identification number is used to determine the resource starting position in the configuration information;

[0156] The determining the parameter index based on the DCI includes:

[0157] Determining the parameter index based on the explicit indication or implicit indication parameter index method adopted by the DCI.

[0158] Specifically, the configuration information received by the terminal from the network-side device includes: the resource starting position startingPRB and the channel resource identification number (pucch-ResourceId). This configuration information corresponds to Scheme B. Among them, there is no parameter index (index) in the configuration information

[0159] The terminal receives the downlink control information DCI sent by a network-side device (such as a base station), determines the indication information corresponding to the pucch-ResourceId according to the PRI in the DCI, the terminal UE finds the matching starting PRB in the configuration information according to the pucch-ResourceId, determines the parameter index according to the DCI, and then determines the number of PUCCH channel RBs (nrofPRBs), and further determines the PUCCH frequency-domain resource location.

[0160] Determining the parameter index based on the DCI includes: determining the parameter index based on the explicit indication or implicit indication parameter index method adopted by the DCI.

[0161] Specifically, the method for the DCI to determine the parameter index can be explicit indication or implicit indication. When using explicit indication, it can be directly included in the parameters corresponding to the downlink control information DCI; when using implicit indication, it is determined by other parameters indirectly associated with the downlink control information DCI.

[0162] Optionally, the determining the parameter index based on the DCI using the explicit indication parameter index method includes:

[0163] Determining the parameter index based on the bit field in the DCI;

[0164] The determining the parameter index based on the DCI using the implicit indication parameter index method includes:

[0165] Determining the parameter index based on the number of CCEs carried by the DCI.

[0166] Specifically, in the case where the DCI uses explicit indication, the parameter index is determined based on the bit field in the DCI. That is, the parameter index for determining the number of PUCCH channel PRBs (nrofPRBs) is indicated by the bit field in the DCI;

[0167] In the case where the DCI uses implicit indication, the parameter index is determined based on the number of CCEs carried by the DCI. That is, the parameter index for determining the number of PUCCH channel RBs (nrofPRBs) is indicated by the number of CCEs (Control Channel Elements) carried by the DCI. The larger the number of CCEs, the more the corresponding number of RBs.

[0168] The uplink control channel resource configuration method provided by the embodiments of this application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side. When the parameter index is not included in the configuration information, the parameter index can be determined by the explicit indication or implicit indication of the parameter index adopted by the DCI. And the first resource set that matches is determined from the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel occupied by the access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, flexible configuration of the uplink control channel resources is achieved.

[0169] Optionally, determining the parameter index based on the bit field in the DCI includes:

[0170] Determining the value of the parameter index based on the value of the bit field in the DCI;

[0171] The bit width of the bit field in the DCI is determined based on the value of the current subcarrier spacing SCS.

[0172] Specifically, the range of the parameter index is determined according to the bit width corresponding to the bit field in the DCI. For example, if the bit width of the DCI bit field is N, the value range of the index of the corresponding number of RBs (nrofPRBs) can be [0, 2 N -1]. And the value of the parameter index is determined according to the value of the bit field in the DCI, and the bit width of the bit field in the DCI is determined according to the value of the current subcarrier SCS. For example, if the bit width of the bit field is 3 and the value of the bit field is 101, that is, the value of the bit field is 5, then the corresponding value of the parameter index is 5.

[0173] The uplink control channel resource configuration method provided by the embodiments of this application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side. When the parameter index is not included in the configuration information, the parameter index can be determined by the explicit indication or implicit indication of the parameter index adopted by the DCI. And the first resource set that matches is determined from the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel occupied by the access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, flexible configuration of the uplink control channel resources is achieved.

[0174] Optionally, the number of RBs occupied by the uplink control channel represented by each element in the first resource set indicated in an enumeration manner is a series of discontinuous values or a series of continuous values.

[0175] Specifically, when the terminal receives the configuration information corresponding to Solution B sent by the network side, the number of resource blocks (RB numbers) occupied by the uplink control channel indicated by each element in the first resource set indicated in an enumeration manner can be flexibly configured as discontinuous data or consecutive values.

[0176] The uplink control channel resource configuration method provided by the embodiments of this application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side. When the parameter index is not included in the configuration information, the parameter index can be determined by means of explicit indication or implicit indication of the parameter index adopted by the DCI. The corresponding resources can be consecutive or discontinuous. And the first resource set that matches is determined from the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel that need to be occupied for access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier spacing (SCS). Thus, flexible configuration of the uplink control channel resources is achieved.

[0177] Optionally, when the target subcarrier spacing (SCS) is an integer multiple of the current subcarrier spacing (SCS), the second resource set determined based on the RB value range corresponding to the target subcarrier spacing (SCS) is a subset of the first resource set.

[0178] Specifically, when the target subcarrier spacing (SCS) is an integer multiple of the current subcarrier spacing (SCS), for example, when the current subcarrier spacing (SCS) = 120 KHz, the corresponding first resource set can be {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32}, and when the target subcarrier spacing (SCS) = 480 KHz, the corresponding second resource set is a subset of the first resource set, such as {nrofPRBs1, nrofPRBs2, nrofPRBs4} or {nrofPRBs1, nrofPRBs4, nrofPRBs16, nrofPRBs20, nrofPRBs24} or {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24}. The above is only an exemplary illustration.

[0179] The uplink control channel resource configuration method provided by the embodiment of the present application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side, and determines a matching first resource set in the configuration information through the downlink control information sent by the network side, and further determines the number of RBs in the uplink control channel that need to be occupied for access. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, flexible configuration of the uplink control channel resources is achieved.

[0180] Optionally, the method further includes:

[0181] When the parameter index is not correctly obtained or the number of RBs calculated based on the parameter index exceeds the RB value range corresponding to the current subcarrier spacing SCS, the default value of the number of RBs corresponding to different subcarrier spacings SCS preset by the network side device is used as the number of RBs occupied by the uplink control channel.

[0182] Specifically, the network side device will pre-define the number of RBs corresponding to different subcarrier spacings SCS. When the terminal encounters an abnormal situation, it can also continue the next step according to the default value. The abnormal situation may include: when the terminal receives the configuration information and cannot normally parse the parameter index in the configuration information, or the number of RBs calculated according to the parameter index exceeds the RB value range corresponding to the current subcarrier spacing SCS. At this time, the default number of RBs is used as the number of RBs occupied by the uplink control channel.

[0183] The uplink control channel resource configuration method provided by the embodiment of the present application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side, and determines a matching first resource set in the configuration information through the downlink control information sent by the network side, and further determines the number of RBs in the uplink control channel that need to be occupied for access. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, flexible configuration of the uplink control channel resources is achieved.

[0184] Figure 2 It is the second flow diagram of the uplink control channel resource configuration method provided by the embodiment of the present application; as Figure 2 shown, the embodiment of the present application provides an uplink control channel resource configuration method, which is applied to a network side device and includes:

[0185] Step 201: Send configuration information of uplink control channel resources to the terminal, where the configuration information at least includes a resource start position;

[0186] Specifically, in the embodiments of the present application, a network-side device, such as an access network device, a base station, sends configuration information of uplink control channel resources to a terminal, and the configuration information includes a resource start position, and may further include a first quantity of resource blocks (RBs) occupied by the uplink control channel, an uplink control channel resource identification number, etc. Among them, the resource start position is the start position of the RB resource block. The RB resource block may be a PRB (Physical Resource Block) or a VRB (Virtual Resource Block), which is not limited in the present application.

[0187] Then, the terminal determines the uplink control channel resources required by the terminal according to the resource start position sent by the network-side device and in combination with the first quantity of resource blocks (RBs) occupied by the uplink control channel.

[0188] Step 202: Send downlink control information (DCI) to the terminal, where the DCI is used to indicate a parameter index, and the parameter index is used to determine a first quantity of resource blocks (RBs) occupied by the uplink control channel in a first resource set; where the first resource set includes multiple elements, the parameter index corresponding to each element is the index of each element in the first resource set, and each element corresponds to the quantity of RBs occupied by the uplink control channel; the multiple elements included in the first resource set are determined based on the value range of RBs corresponding to the current subcarrier spacing (SCS); where the resource start position and the first quantity of resource blocks (RBs) occupied by the uplink control channel are used to determine the uplink control channel resources.

[0189] Specifically, in the embodiments of the present application, the corresponding RB value range is determined according to the current subcarrier SCS. For example, when the current subcarrier SCS = 120 KHZ, the corresponding RB value range is [1, 8]. Furthermore, the number of elements included in the first resource set is determined through the RB value range. For example, when the current RB value range is [1, 8], the first resource set contains at most 8 elements and at least 1 element. The value of each element represents the quantity of RBs occupied by the uplink control channel.

[0190] The network-side device sends downlink control information (DCI) to the terminal. After the terminal receives the DCI, it determines the parameter index for the number of RBs of the uplink control channel according to the DCI. In the present application, it is simply referred to as the parameter index. There is a one-to-one relationship between this parameter index and the number of RBs of the uplink control channel. Through this index, the number of RBs of the uplink control channel corresponding to this terminal, that is, the first quantity, can be found. For example, when the value of the number of RBs (nrofPRBs) is 8, the corresponding parameter index index is 7.

[0191] The uplink control channel resource configuration method provided by the embodiments of this application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side, and determines a matching first resource set in the configuration information through the downlink control information sent by the network side, and then determines the number of RBs in the uplink control channel that need to be occupied for access. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS.

[0192] Optionally, the configuration method of the first resource set includes any one of the following:

[0193] Method 1: Configure the first resource set based on RRC signaling and indicate it in an enumerated manner;

[0194] Method 2: Obtain the first resource set based on the RB value range corresponding to the current subcarrier spacing SCS and a pre-set calculation rule.

[0195] Specifically, when the configuration method adopts Method 1, the configuration of the first resource set can be in an enumerated manner and directly configured based on RRC signaling.

[0196] There is an implementation scenario. For example, when SCS = 120 kHz, the number of PUCCH channel RBs is represented by nrofPRBs, and the corresponding first resource set values can be {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32}; the parameter index of the number of PRBs (nrofPRBs) is the index of the elements in the set. For example, index = 0 corresponds to nrofPRBs1; index = 1 corresponds to nrofPRBs2.

[0197] Another implementation scenario All integers within the range. Where is the minimum number of RBs configurable for PUCCH under a certain SCS value, is the maximum number of RBs configurable for PUCCH under a certain SCS value.

[0198] When the configuration method adopts Method 2, the first resource set is obtained based on the RB value range corresponding to the current subcarrier spacing SCS and a pre-set calculation rule.

[0199] There are multiple values for the current subcarrier spacing SCS, such as 120 KHZ, 480 KHZ, 960 KHZ, etc. According to different SCS values, the corresponding different RB value ranges are determined, and based on the pre-set calculation rules, the first resource set is further calculated and obtained.

[0200] Among them, there are mainly two pre-set calculation rules: the first calculation formula and the second calculation formula.

[0201] The first calculation formula is:

[0202]

[0203] Among them, nrofPRBs(index) is an element in the first resource set, and index is the parameter index corresponding to each element. is the minimum number of RBs configurable for PUCCH under the current subcarrier spacing SCS value. is the maximum number of RBs configurable for PUCCH under the current subcarrier spacing SCS value, and N is the number of bits required to indicate the PUCCH RB number.

[0204] The network side device determines the corresponding minimum number of RBs configurable for PUCCH according to the current subcarrier spacing SCS. and the maximum number of RBs. And obtains the number of bits N required to indicate the PUCCH RB number through RRC signaling, and determines each element in the first resource set based on the first calculation formula.

[0205] The second calculation formula is:

[0206]

[0207] Among them, nrofPRBs(index) is an element in the first resource set, and index is the parameter index corresponding to each element. is the minimum number of RBs configurable for PUCCH under the current subcarrier spacing SCS value. is the maximum number of RBs configurable for PUCCH under the current subcarrier spacing SCS value, and k(dB) is the granularity of the PUCCH transmit power adjustment, that is, the step size of the PUCCH transmit power adjustment.

[0208] The network side device determines the corresponding minimum number of RBs configurable for PUCCH according to the current subcarrier spacing SCS. and the maximum number of RBs. And sets the granularity k(dB) of the PUCCH transmit power adjustment, and determines each element in the first resource set based on the second calculation formula.

[0209] The uplink control channel resource configuration method provided by the embodiments of the present application calculates the configurable value of the PUCCH channel resource granularity by directly notifying the enumeration set of the number of RBs of the PUCCH, or by setting the calculation formula of the number of RBs of the PUCCH and notifying the relevant parameters to determine the set of the number of RBs of the PUCCH, and determines the number of channel RBs of the PUCCH through DCI indication, so as to be able to flexibly configure the number of RBs of the PUCCH.

[0210] Optionally, the configuration information further includes the parameter index and the channel resource identification number;

[0211] The DCI includes the channel resource identification number, and the channel resource identification number is used to determine the parameter index and the resource start position.

[0212] Specifically, the configuration information sent by the network side device includes: the resource start position startingPRB, the parameter index index, and the channel resource identification number (pucch-ResourceId). This configuration information corresponds to Scheme A.

[0213] Wherein the parameter index index represents the index for determining the number of RBs (nrofPRBs) of the PUCCH channel. When the index is different, the determined nrofPRBs may have discontinuous values.

[0214] The network side device, such as a base station, sends downlink control information DCI to the terminal, and provides an indication of pucch-ResourceId to the terminal UE through the PRI parameter in the DCI, so that the terminal UE can determine nrofPRBs and startingPRB according to pucch-ResourceId and the configuration information. Furthermore, the PUCCH frequency domain resource position of the terminal is determined according to the above parameters.

[0215] Optionally, the number of RBs occupied by the uplink control channel represented by each element in the first resource set indicated in an enumeration manner is a series of discontinuous values.

[0216] The network side device sends the configuration information corresponding to Scheme A, and the elements in the first resource set are discontinuous values, and each element represents the number of RBs occupied by the uplink control channel, so as to realize the configuration of the uplink control channel resource in a discontinuous interval and enable flexible configuration of the uplink control channel resource.

[0217] The uplink control channel resource configuration method provided by the embodiments of the present application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side. When the configuration information includes a parameter index, the number of PUCCH channel RBs configured is discontinuous. And a first resource set that matches is determined from the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel that need to be occupied for access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS.

[0218] Optionally, the configuration information further includes a channel resource identification number; the DCI includes the channel resource identification number, and the channel resource identification number is used to determine the starting position of the resource in the configuration information;

[0219] The DCI uses an explicit indication or an implicit indication method to indicate the parameter index.

[0220] Specifically, the configuration information sent by the network side device includes: the starting PRB of the resource and the channel resource identification number (pucch-ResourceId). This corresponds to Scheme B in the configuration information. Among them, there is no parameter index (index) in the configuration information

[0221] The network side device, such as a base station, indicates the pucch-ResourceId to the UE through the PRI in the scheduling signaling DCI. The UE determines the starting PRB according to the pucch-ResourceId and the configuration information, and determines the parameter index according to the DCI, and then determines the number of PUCCH channel RBs (nrofPRBs), and then determines the PUCCH frequency domain resource position.

[0222] Determining the parameter index based on the DCI includes: determining the parameter index based on the explicit indication or implicit indication method of the parameter index adopted by the DCI.

[0223] Specifically, the method for the DCI to determine the parameter index can be explicit indication or implicit indication. When using explicit indication, it can be directly included in the parameters corresponding to the downlink control information DCI; when using implicit indication, it is determined by other parameters indirectly associated with the downlink control information DCI.

[0224] Optionally, the method for the DCI to indicate the parameter index using the explicit indication method includes:

[0225] Indicating the parameter index based on the bit field in the DCI;

[0226] The method for the DCI to indicate the parameter index using the implicit indication method includes:

[0227] The parameter index is indicated based on the number of CCEs carried by the DCI.

[0228] Specifically, in the case where the DCI uses explicit indication, the network device sends downlink control information DCI to the terminal, and the terminal determines the parameter index based on the bit field in the DCI. That is, the parameter index for determining the number of PUCCH channel RBs (nrofPRBs) is indicated through the bit field in the DCI.

[0229] In the case where the DCI uses implicit indication, the network device sends downlink control information DCI to the terminal, and the terminal determines the parameter index based on the number of CCEs carried by the DCI. That is, the parameter index for determining the number of PUCCH channel RBs (nrofPRBs) is indicated through the number of CCEs (Control Channel Elements) carried by the DCI. The larger the number of CCEs, the more RBs correspond to it.

[0230] The method for configuring uplink control channel resources provided by the embodiments of the present application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side. When the parameter index is not included in the configuration information, the parameter index can be determined by the explicit indication or implicit indication parameter index method adopted by the DCI. And the matching first resource set is determined in the configuration information through the downlink control information sent by the network side, and then the number of RBs that need to be occupied in the uplink control channel for access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, the flexible configuration of the uplink control channel resources is realized.

[0231] Determining the parameter index based on the bit field in the DCI includes:

[0232] Determining the value of the parameter index based on the value of the bit field in the DCI;

[0233] The bit width of the bit field in the DCI is determined based on the value of the current subcarrier spacing SCS.

[0234] Specifically, according to the bit width corresponding to the bit field in the DCI, the range of the parameter index is determined. For example, if the bit width of the DCI bit field is N, the value range of the index of the corresponding number of RBs (nrofPRBs) can be [0, 2 N -1]. And the value of the parameter index is determined according to the value of the bit field in the DCI, and the bit width of the bit field in the DCI is determined according to the value of the current subcarrier SCS. For example, if the bit width of the bit field is 3 and the value of the bit field is 101, that is, the value of the bit field is 5, then the corresponding value of the parameter index is 5.

[0235] The uplink control channel resource configuration method provided by the embodiments of the present application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side. When the configuration information does not include a parameter index, the parameter index can be determined by the explicit indication or implicit indication of the parameter index adopted by the DCI. And the first resource set that matches is determined from the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel occupied by the access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, flexible configuration of the uplink control channel resources is achieved.

[0236] Optionally, the number of RBs occupied by the uplink control channel represented by each element in the first resource set indicated in an enumeration manner is a series of discontinuous values or a series of continuous values.

[0237] Specifically, when the configuration information corresponding to solution B sent by the network side is received, the number of resource blocks (number of RBs) occupied by the uplink control channel represented by each element in the first resource set indicated in an enumeration manner can be flexibly configured as discontinuous data or continuous values.

[0238] The uplink control channel resource configuration method provided by the embodiments of the present application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side. When the configuration information does not include a parameter index, the parameter index can be determined by the explicit indication or implicit indication of the parameter index adopted by the DCI. The corresponding resources can be continuous or discontinuous. And the first resource set that matches is determined from the configuration information through the downlink control information sent by the network side, and then the number of RBs in the uplink control channel occupied by the access is determined. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, flexible configuration of the uplink control channel resources is achieved.

[0239] Optionally, in the case where the target subcarrier spacing SCS is an integer multiple of the current subcarrier spacing SCS, the second resource set determined based on the RB value range corresponding to the target subcarrier spacing SCS is a subset of the first resource set.

[0240] Specifically, when the target subcarrier spacing SCS is an integer multiple of the current subcarrier spacing SCS, for example, when the current subcarrier spacing SCS = 120 KHz, the corresponding first resource set can be {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24} or {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs24, nrofPRBs32}, and when the target subcarrier spacing SCS = 480 KHz, the corresponding second resource set is a subset of the first resource set, such as {nrofPRBs1, nrofPRBs2, nrofPRBs4} or {nrofPRBs1, nrofPRBs4, nrofPRBs16, nrofPRBs20, nrofPRBs24} or {nrofPRBs1, nrofPRBs2, nrofPRBs4, nrofPRBs8, nrofPRBs12, nrofPRBs16, nrofPRBs20, nrofPRBs24}. The above is only an exemplary illustration.

[0241] The uplink control channel resource configuration method provided by the embodiments of this application pre-configures the uplink control channel resources through the configuration information of the uplink control channel resources sent by the network side, determines the matching first resource set in the configuration information through the downlink control information sent by the network side, and then determines the number of RBs in the uplink control channel that need to be occupied for access. And the first resource set is determined based on the RB value range corresponding to the current subcarrier SCS. Thus, flexible configuration of the uplink control channel resources is achieved.

[0242] Optionally, the method further includes:
