Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to communication methods and communication devices, as well as computer-readable storage media.

Background Art

[0002] The Physical Uplink Control Channel (PUCCH) is an uplink physical channel in a New Radio (NR) system and is used to carry uplink control information (UCI).

[0003] In an uplink subframe, to maximize the frequency diversity of control signaling, the PUCCH is placed on both the high side and the low side of a bandwidth part (BWP), or at the edge of the frequency band. The PUCCH uses physical resource block (PRB) pairs as a basic unit, that is, two PRBs in a PRB pair are placed at the edge of the frequency band. For example, FIG. 1 is a schematic diagram showing the positions of PRB pairs according to an embodiment of the present application. As shown in FIG. 1, two PRBs corresponding to each of the PUCCH0 resource, the PUCCH1 resource, and the PUCCH2 resource are respectively placed at the edge of the BWP.

[0004] Before the radio resource control (RRC) layer is established, the base station cannot configure dedicated PUCCH resources for the UE by using signaling, and the PUCCH resources are pre-defined in the protocol. The specific method is as follows. That is, the base station uses the system information block 1 (SIB1) to configure a common PUCCH resource set for all UEs before the establishment of RRC. The PUCCH resources in the PUCCH resource set need to transmit only 1-bit or 2-bit acknowledgment response information, that is, it needs to include only PUCCH format 0 and PUCCH format 1. Therefore, the transmission of each PUCCH resource occupies one physical resource block (PRB). As shown in FIG. 1, the frequency domain frequency hopping distances of some PUCCH resources are different. For example, the frequency domain frequency hopping distance of PUCCH0 is larger than that of PUCCH2. The PUCCH resource whose frequency domain position is farther from the edge of the BWP has a shorter frequency domain frequency hopping distance, which indicates that the frequency hopping gain is smaller. As a result, a certain degree of coverage degradation occurs. Therefore, how to relax the limitation of the frequency hopping gain of the PUCCH resources and how to expand the coverage are urgent problems to be solved. Summary of the Invention

[0005] Embodiments of the present application provide a communication method, a communication device, and a computer-readable storage medium for relaxing the limitation of the frequency hopping gain of PUCCH resources and expanding the coverage.

[0006] According to a first aspect, the present application provides a communication method. This communication method can be applied to a terminal device or to a module (e.g., a chip, etc.) in a terminal device. For the sake of explanation, an example where this communication method is applied to a terminal is used below. The method may include the following. That is, a step of receiving first indication information from a network device, where the first indication information is used to determine a frequency domain position to which a physical uplink control channel PUCCH resource is mapped. And a step of transmitting information to the network device during a first period by using the PUCCH resource, where the frequency domain positions to which the PUCCH resource is mapped in at least two consecutive time units during the first period are different.

[0007] In the solution provided in the present application, during a specific consecutive time period when a terminal device transmits information by using the PUCCH, the frequency domain position to which the PUCCH resource is mapped changes with time. This is different from that in the prior art where the frequency domain position to which the PUCCH resource is mapped remains unchanged in each slot of the PUCCH transmission. In the present embodiment of the present application, the frequency domain position to which the PUCCH resource is mapped changes, whereby the frequency domain frequency hopping distances of all PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0008] In a possible implementation, when the network device does not configure the frequency domain position to which a dedicated PUCCH resource is mapped for the terminal device, the frequency domain position to which the PUCCH resource is mapped is determined based on a PRB offset and an initial cyclic shift index set.

[0009] In the solution provided in this application, when the terminal device accesses the network, the network device can configure dedicated PUCCH resources for the terminal device by using dedicated RRC signaling. However, before the establishment of RRC, the network device cannot configure dedicated PUCCH resources for the terminal device by using dedicated RRC signaling, and the PUCCH resources are pre-defined in the protocol. Specifically, the network device configures a common PUCCH resource set for all terminal devices before the establishment of RRC by using SIB1. The terminal device can determine the frequency domain position where the PUCCH resource is mapped based on the PRB offset and the initial cyclic shift index set in the resource set. During a specific continuous time period during PUCCH transmission in the terminal device, the frequency domain position where the used PUCCH resource is mapped changes with time, so that the frequency domain hopping distance of all PUCCH resources can be the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0010] In a possible implementation, the frequency domain position where the PUCCH resource is mapped includes the starting PRB index of the PUCCH resource at the first mapping position, the starting PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource. That the frequency domain position where the PUCCH resource is mapped is determined based on the PRB offset and the initial cyclic shift index set

[0011]

Number

[0012] is the case, the starting PRB index of the PUCCH resource at the first mapping position is

[0013]

Number

[0014] and the starting PRB index of the PUCCH resource at the second mapping position is

[0015]

Number

[0016] and the initial cyclic shift index of the PUCCH resource is r PUCCH mod N CS or

[0017]

[0018] if so, the starting PRB index of the PUCCH resource at the first mapping position is

[0019]

Number

[0020] and the starting PRB index of the PUCCH resource at the second mapping position is

[0021]

Number

[0022] and the initial cyclic shift index of the PUCCH resource is (r PUCCH -8) mod N CS including that.

[0023]

Number

[0024] is the PRB offset, r PUCCH is the index of the PUCCH resource, N CS is the total number of initial cyclic shift indices in the initial cyclic shift index set,

[0025]

Number

[0026] is the number of PRBs occupied by the bandwidth part BWP, N is the number of PRBs occupied by the PUCCH resource, and N is a positive integer greater than or equal to 1.

[0027] Before the establishment of RRC, the network device cannot configure dedicated PUCCH resources for the UE by using signaling, and the PUCCH resources are pre-defined in the protocol. The specific method is as follows. That is, the network device uses SIB1 to configure a common PUCCH resource set for all terminal devices before the establishment of RRC. The PUCCH resources in the PUCCH resource set only need to transmit 1-bit or 2-bit acknowledgment response information, that is, only include PUCCH format 0 and PUCCH format 1. Therefore, the transmission of each PUCCH resource occupies one PRB. In the solution provided in this application, the transmission of each PUCCH resource can occupy one or more PRBs. The first possible determination mode for the terminal device to determine the frequency domain position where the PUCCH resource is mapped is different from that in the prior art. According to the above formula and based on frequency division multiplexing, the step is to determine the start PRB index of the PUCCH resource at the first mapping position, the start PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource. In this mode of determining the frequency hopping pattern, the possibility that different PUCCH resources overlap in the frequency domain can be reduced. Since the transmission of each PUCCH resource occupies multiple PRBs, the transmission coverage of PUCCH can be improved when the constraints of the maximum transmission power and the power spectral density are met.

[0028] In a possible implementation, the frequency domain position where the PUCCH resource is mapped includes the start PRB index of the PUCCH resource at the first mapping position, the start PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource. That the frequency domain position where the PUCCH resource is mapped is determined based on the PRB offset and the initial cyclic shift index set is

[0029]

Number

[0030] If it is the case, the starting PRB index of the PUCCH resource at the first mapping position is

[0031]

Number

[0032] and the starting PRB index of the PUCCH resource at the second mapping position is

[0033]

Number

[0034] and the initial cyclic shift index of the PUCCH resource is r PUCCH mod N CS or

[0035]

Number

[0036] If it is the case, the starting PRB index of the PUCCH resource at the first mapping position is

[0037]

Number

[0038] and the starting PRB index of the PUCCH resource at the second mapping position is

[0039]

Number

[0040] and the initial cyclic shift index of the PUCCH resource is (r PUCCH - 8) mod N CS including that

[0041] [Number]

[0042] is the PRB offset, r PUCCH is the index of the PUCCH resource, N CS is the total number of initial cyclic shift indexes in the initial cyclic shift index set,

[0043] [Number]

[0044] is the number of PRBs occupied by the bandwidth part BWP, N is the number of PRBs occupied by the PUCCH resource, and N is a positive integer of 1 or more.

[0045] In the solution provided in this application, the transmission of each PUCCH resource may occupy one or more PRBs. For the first possible determination mode in which the terminal device determines the frequency domain position where the PUCCH resource is mapped, alternatively, according to a formula different from that in the prior art, it may be to determine the start PRB index of the PUCCH resource at the first mapping position, the start PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource.

[0046] [Number]

[0047] Accordingly, a modulo operation is performed on the result of N times the RB offset, so that the PUCCH frequency domain resource index does not exceed the BWP range due to an overly large RB offset of the PUCCH resource. This can mitigate the RB shortage problem. Also, more combinations of configurations in the PUCCH resource set and N can be added. Since the transmission of each PUCCH resource occupies multiple PRBs, the transmission coverage of the PUCCH can be improved when the constraints on the maximum transmission power value and the power spectral density are satisfied.

[0048] In a possible implementation, the frequency domain position where the PUCCH resource is mapped includes the starting PRB index of the PUCCH resource at the first mapping position, the starting PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource.

For the first possible determination mode in which the terminal device determines the frequency domain position where the PUCCH resource is mapped, alternatively, according to the above formula, the starting PRB index of the PUCCH resource at the first mapping position, the starting PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource can be determined. The modulo position of the calculation formula is adjusted, so that the initial RB position of the PUCCH resource does not exceed the BWP range. This can reduce the RB shortage problem. In addition, more combinations of configurations in the PUCCH resource set and N can be added. Since the transmission of each PUCCH resource occupies multiple PRBs, the transmission coverage of the PUCCH can be improved when the constraints of the maximum transmission power and the power spectral density are satisfied.

[0109] is. Since the maximum value of N is 16, the scaling degree of the RB offset is restricted by using a certain formula, and the RB offset does not increase linearly with the increase of N.

[0176] Before the establishment of RRC, the network device cannot configure dedicated PUCCH resources for the UE by using signaling, and the PUCCH resources are predefined in the protocol. The specific method is as follows. That is, the network device configures a common PUCCH resource set for all terminal devices before the establishment of RRC by using SIB1. The PUCCH resources in the PUCCH resource set only need to transmit confirmation response information of 1 bit or 2 bits, that is, only PUCCH format 0 and PUCCH format 1 need to be included. Therefore, the transmission of each PUCCH resource occupies one PRB. In the solution provided in this application, the transmission of each PUCCH resource may occupy one or more PRBs, and the second possible determination manner for the terminal device to determine the frequency domain position where the PUCCH resource is mapped is to determine the start PRB index of the PUCCH resource at the first mapping position, the start PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource according to the above formula. Since the transmission of each PUCCH resource occupies a plurality of PRBs, the transmission coverage of PUCCH can be improved when the constraints of the maximum transmission power and the power spectral density are satisfied. Also, the first PUCCH resource is closest to the ends on both sides of the BWP, thereby ensuring the maximum coverage capability. Each PUCCH resource of the second PUCCH resource has the same frequency domain position distance, and thereby each PUCCH resource of the second PUCCH resource has the same frequency hopping gain. This can reduce the degradation of the coverage.

[0177] In a possible implementation, the fact that the frequency domain positions where the PUCCH resource is mapped in at least two consecutive time units in the first period are different includes the following. That is, in at least two consecutive time units,

[0178]

Number

[0179] When it is the case, the starting PRB index of the PUCCH resource at the first mapping position is periodically shifted by only N PRBs in ascending order of the PRB index, and the starting PRB index of the PUCCH resource at the second mapping position is periodically shifted by only N PRBs in descending order of the PRB index, or

[0180]

Number

[0181] When it is the case, the starting PRB index of the PUCCH resource at the first mapping position is periodically shifted by only N PRBs in descending order of the PRB index, and the starting PRB index of the PUCCH resource at the second mapping position is periodically shifted by only N PRBs in ascending order of the PRB index. Alternatively, in at least two consecutive time units,

[0182]

Number

[0183] When it is the case, the starting PRB index of the PUCCH resource at the first mapping position is periodically shifted by only N PRBs in descending order of the PRB index, and the starting PRB index of the PUCCH resource at the second mapping position is periodically shifted by only N PRBs in ascending order of the PRB index, or

[0184]

Number

[0185] When it is the case, the starting PRB index of the PUCCH resource at the first mapping position is periodically shifted by only N PRBs in ascending order of the PRB index, and the starting PRB index of the PUCCH resource at the second mapping position is periodically shifted by only N PRBs in descending order of the PRB index.

[0186] In the solution provided in this application, in the first aspect where the terminal device determines the frequency domain position where the PUCCH resource is mapped, after the frequency domain position where the PUCCH resource is mapped is determined, the terminal device can transmit information to the network device within a specific period by using the PUCCH resource. In at least two consecutive time units within this period, the frequency domain position where the PUCCH resource is mapped may change with the time unit. The starting PRB index of the PUCCH resource at the first mapping position and the starting PRB index of the PUCCH resource at the second mapping position can be periodically shifted by only N PRBs from both sides of the BWP to the middle of the BWP, or can be periodically shifted by only N PRBs from the middle of the BWP to both sides of the BWP. Since the frequency domain position where the PUCCH resource is mapped changes, in this way, the frequency domain hopping distance of all PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0187] In a possible implementation, the fact that the frequency domain positions where the PUCCH resource is mapped are different in at least two consecutive time units in the first period includes the following. That is, in the M-th time unit among at least two consecutive time units,

[0199] where K is a fixed time domain cyclic offset and M is an integer greater than or equal to 1.

[0200] In the solution provided in this application, in the first aspect where the terminal device determines the frequency domain position to which the PUCCH resource is mapped, after the frequency domain position to which the PUCCH resource is mapped is determined, the terminal device can transmit information to the network device within a specific period by using the PUCCH resource. In at least two consecutive time units during this period, the frequency domain position to which the PUCCH resource is mapped may change with the time unit. The start PRB index of the PUCCH resource at the first mapping position and the start PRB index of the PUCCH resource at the second mapping position can be periodically shifted by N PRBs from both sides of the BWP to the middle of the BWP, or can be periodically shifted by N PRBs from the middle of the BWP to both sides of the BWP. Since the frequency domain position to which the PUCCH resource is mapped changes, in this way, the frequency domain hopping distance of all PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0218] In the solution provided in this application, in the second aspect where the terminal device determines the frequency domain position where the PUCCH resource is mapped, after the frequency domain position where the PUCCH resource is mapped is determined, the terminal device can transmit information to the network device within a specific period by using the PUCCH resource. In at least two consecutive time units within this period, the frequency domain position where the PUCCH resource is mapped may change with the time unit. The start PRB index of all PUCCH resources at the first mapping position and the start PRB index of the second PUCCH resource at the second mapping position can be periodically shifted by N PRBs from both sides of the BWP to the middle of the BWP, or can be periodically shifted by N PRBs from the middle of the BWP to both sides of the BWP. The frequency domain position where the PUCCH resource is mapped changes, so that the frequency domain hopping distance of all PUCCH resources can be averaged to be the same in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0245] In the solution provided in this application, in the second aspect where the terminal device determines the frequency domain position to which the PUCCH resource is mapped, after the frequency domain position to which the PUCCH resource is mapped is determined, the terminal device can transmit information to the network device within a specific period by using the PUCCH resource. In at least two consecutive time units during this period, the frequency domain position to which the PUCCH resource is mapped may change with the time unit. The start PRB index of all PUCCH resources at the first mapping position and the start PRB index of the second PUCCH resource at the second mapping position can be periodically shifted by N PRBs from both sides of the BWP to the middle of the BWP, or can be periodically shifted by N PRBs from the middle of the BWP to both sides of the BWP. The frequency domain position to which the PUCCH resource is mapped changes, whereby the frequency domain hopping distance of all PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0246] In a possible implementation, the fact that the frequency domain positions to which the PUCCH resource is mapped are different in at least two consecutive time units in the first period includes the following. That is, in at least two consecutive time units,

[0263] In the solution provided in this application, in the second aspect where the terminal device determines the frequency domain position to which the PUCCH resource is mapped, after the frequency domain position to which the PUCCH resource is mapped is determined, the terminal device can transmit information to the network device within a specific period by using the PUCCH resource. In at least two consecutive time units within this period, the frequency domain position to which the PUCCH resource is mapped may change with the time unit. The start PRB index of all PUCCH resources at the first mapping position is periodically shifted by N PRBs from both sides of the BWP to the middle of the BWP, and the start PRB index at the second mapping position is periodically shifted by N PRBs from the middle of the BWP to both sides of the BWP, or the start PRB index of all PUCCH resources at the first mapping position is periodically shifted by N PRBs from the middle of the BWP to both sides of the BWP, and the start PRB index at the second mapping position is periodically shifted by N PRBs from both sides of the BWP to the middle of the BWP. The frequency domain position to which the PUCCH resource is mapped changes, so that the frequency domain frequency hopping distance of all PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0264] In a possible implementation, the frequency domain positions where PUCCH resources are mapped include the starting PRB index of the PUCCH resources at the first mapping position and the starting PRB index of the PUCCH resources at the second mapping position. When the network device configures the frequency domain positions where dedicated PUCCH resources are mapped for the terminal device, the fact that the frequency domain positions where the PUCCH resources are mapped in at least two consecutive time units in the first period are different includes the following. That is, in at least two consecutive time units, the starting PRB index of the PUCCH resources at the first mapping position and the starting PRB index of the PUCCH resources at the second mapping position are periodically shifted by a first offset on the physical resource block PRB of the bandwidth part BWP.

[0265] In the solution provided in this application, when the terminal device accesses the network, the network device can configure dedicated PUCCH resources for the terminal device by using dedicated RRC signaling. During a specific consecutive time period during the transmission of the configured dedicated PUCCH in the terminal device, the frequency domain positions where the used dedicated PUCCH resources are mapped change with time, so that the frequency domain frequency hopping distances of all dedicated PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resources and expand the coverage.

[0266] In a possible implementation, the frequency domain positions where PUCCH resources are mapped include the starting PRB index of the PUCCH resources at the first mapping position and the starting PRB index of the PUCCH resources at the second mapping position. When the network device configures for the terminal device the frequency domain positions where dedicated PUCCH resources are mapped, the fact that the frequency domain positions where the PUCCH resources are mapped in at least two consecutive time units in the first period are different includes the following. That is, in at least two consecutive time units, the starting PRB index of the PUCCH resources at the first mapping position and the starting PRB index of the PUCCH resources at the second mapping position are each periodically shifted by a first offset and a second offset on the physical resource block (PRB) of the bandwidth part (BWP).

[0267] In the solution provided in this application, when the terminal device accesses the network, the network device can configure dedicated PUCCH resources for the terminal device by using dedicated RRC signaling. During a specific consecutive time period during the transmission of the configured dedicated PUCCH in the terminal device, the frequency domain positions where the used dedicated PUCCH resources are mapped change with time, so that the frequency domain frequency hopping distances of all the dedicated PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resources and expand the coverage.

[0268] In a possible implementation, the first offset is configured according to the network device by using the dedicated radio resource control (RRC) layer.

[0269] In a possible implementation, the second offset is configured according to the network device by using the dedicated radio resource control (RRC) layer.

[0270] In a possible implementation, the method further includes a step of receiving second indication information from a network device, where the second indication information indicates that the start time unit of at least two consecutive time units is the time unit when the terminal device first uses the PUCCH resource.

[0271] In the solution provided in this application, the network device can indicate the start time unit by using the indication information, and the frequency domain position where the PUCCH resource is mapped changes starting from the start time unit.

[0272] In a possible implementation, the method further includes a step of receiving second indication information from a network device, where the second indication information includes a time period offset, and the second indication information indicates that the start time unit of at least two consecutive time units is the time unit obtained by adding the time period offset to the time unit when the terminal device receives the second indication information.

[0273] In a possible implementation, the method further includes a step of receiving second indication information from a network device, where the second indication information includes a time unit index value, and the second indication information indicates that the start time unit of at least two consecutive time units is the time unit corresponding to the time unit index value.

[0274] According to a second aspect, the present application provides a communication method. This method can be applied to a network device or to a module (such as a chip, etc.) in a network device. For the sake of explanation, an example where this method is applied to a network device is used below. This method may include the following. That is, a step of transmitting first indication information to a terminal device, where the first indication information is used to determine a frequency domain position to which a physical uplink control channel PUCCH resource is mapped. And a step of receiving information from the terminal device during a first period, where the frequency domain positions to which the PUCCH resource is mapped in at least two consecutive time units during the first period are different.

[0275] In the solution provided by the present application, in a specific consecutive time period during which a network device receives information transmitted by a terminal device by using PUCCH, the frequency domain position to which the PUCCH resource is mapped changes with time. Different from that in the prior art, the frequency domain position to which the PUCCH resource is mapped remains unchanged in each slot of PUCCH transmission. In the present embodiment of the present application, the frequency domain position to which the PUCCH resource is mapped changes, so that the frequency domain frequency hopping distances of all PUCCH resources can be averaged to be the same in the time dimension. In this way, the frequency hopping gain is the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resource and expand the coverage.

[0276] It should be understood that when the second aspect is executed by a network device and the specific content in the second aspect corresponds to the content in the first aspect. For the corresponding features of the second aspect and the beneficial effects achieved in the second aspect, please refer to the description of the first aspect. To avoid repetition, in this specification, the detailed description is appropriately omitted as appropriate.

[0277] In a possible implementation, when a network device does not configure for a terminal device the frequency domain position where a dedicated PUCCH resource is mapped, the frequency domain position where the PUCCH resource is mapped is determined based on a PRB offset and an initial cyclic shift index set. A specific implementation where the frequency domain position where the PUCCH resource is mapped is determined based on a PRB offset and an initial cyclic shift index set corresponds to a specific implementation in the first aspect. For details, refer to the description of the first aspect. To avoid repetition, in this specification, detailed descriptions are appropriately omitted.

Embodiments for Carrying Out the Invention

[0964] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings in the embodiments of the present application.

[0965] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application and are not intended to limit the present application.

[0966] First, definitions of technical terms that may be used in the embodiments of the present application are provided.

[0967] (1) Frequency Hopping Spread Spectrum (FHSS)

[0968] Frequency Hopping Spread Spectrum is one of the most commonly used spread spectrum methods in wireless communication. Frequency Hopping Spread Spectrum is a communication method in which the carrier frequency used for wireless signal transmission between a transmitting device and a receiving device changes discretely according to a preset algorithm or rule. In other words, the carrier frequency used for wireless communication randomly jumps under the control of a pseudo-random variable code. From the perspective of the implementation of communication technology, Frequency Hopping Spread Spectrum is a communication method in which multiple frequency shift keying is performed by using a code sequence, and it is also a code-controlled carrier frequency hopping communication system. From the perspective of the time domain, a frequency hopping signal is a multiple frequency shift keying signal. From the perspective of the frequency domain, the frequency spectrum of a frequency hopping signal randomly shifts at unequal intervals over an extremely wide frequency band.

[0969] (2) Circular Shift

[0970] Circular shift is an operation of rearranging an element group by placing the last element at the position of the first element and moving each of the other elements to the next position. For example, (a, b, c, d), (d, a, b, c), (c, d, a, b), (b, c, d, a), (a, b, c, d)... and so on. Alternatively, circular shift may be an operation that is the reverse of the above-described operation.

[0971] To support uplink data transmission, in a communication system, it is necessary to design uplink control signaling. The PUCCH is the basis for uplink control signaling transmission. The PUCCH can be used to transmit uplink control information. When a user equipment (UE) is not scheduled, in other words, when uplink shared channel (ULSCH) resources are not allocated, the UE uses the PUCCH, which includes hybrid automatic repeat request acknowledgment (HARQ-ACK), channel state information (CSI), and scheduling request (SR), to transfer layer 1 or layer 2 (L1 / L2) uplink control information (UCI). Various formats of the PUCCH can be used to transmit the UCI.

[0972] When the UE accesses the network, the base station can configure dedicated PUCCH resources for the UE by using dedicated RRC signaling. Specifically, the physical downlink shared channel (PDSCH) and the PDSCH-to-PUCCH slot index difference set dl-DataToUL-ACK are configured for the UE by using RRC signaling, and the PDSCH-to-PUCCH slot index difference set dl-DataToUL-ACK is used to determine the difference between the slot index for the UE to receive the PDSCH and the slot index for the UE to feedback the PUCCH. The PDSCH-to-HARQ_feedback timing indicator field in the DCI is used to indicate which slot index difference in the set is used. However, before and after the establishment of the RRC, the method of determining the resource set is different.

[0973] Before the establishment of RRC, the base station cannot configure dedicated PUCCH resources for the UE by using signaling, and the PUCCH resources are pre-defined in the protocol. Specifically, the base station configures a common PUCCH resource set for all UEs before the establishment of RRC by using SIB1. The PUCCH resources in the pre-defined PUCCH resource set need to transmit only 1-bit or 2-bit acknowledgment response information, that is, it needs to include only PUCCH format 0 and PUCCH format 1. Therefore, the transmission of each PUCCH resource occupies one PRB. The dedicated PUCCH resources are not configured for the UE in the PUCCH-ResourceSet of PUCCH-Config. The UE transmits HARQ-ACK information in the initial UL BWP by using the PUCCH resources configured in the PUCCH resource set of pucch-ResourceCommon. The UE can determine the PUCCH resources based on the parameter pucch-ResourceCommon configured in SIB1 and Table 1.

[0974]

Table 1

[0975] Specifically, the UE determines the PUCCH resources based on the parameter pucch-ResourceCommon configured in SIB1 and Table 1. Figure 2 is a schematic flowchart of determining PUCCH resources by the UE according to the prior art. As shown in Figure 2, determining PUCCH resources by the UE may include the following steps.

[0976] S201: The base station transmits SIB1 to the UE, and SIB1 carries the parameter pucch-ResourceCommon. The parameter pucch-ResourceCommon is an indication field in the RRC message. The hierarchy of the parameters defined in 38.331 is as follows. That is, SIB1 → ServingCellConfigCommonSIB → UplinkConfigCommonSIB → BWP-UplinkCommon → PUCCH-ConfigCommon → pucch-ResourceCommon.

[0977] S202: The UE determines a PUCCH resource set based on SIB1. After the UE receives SIB1 from the base station, the PUCCH resource set is configured based on the parameter pucch-ResourceCommon, and the value of the parameter is one of 0 to 15. The value of the parameter pucch-ResourceCommon corresponds to the index value in Table 1, and the UE determines the row in Table 1 as the configuration of the PUCCH resource set.

[0978] S203: The base station transmits PDCCH to the UE, and PDCCH contains downlink control information (DCI), and DCI indicates the modulation and coding scheme of the PDSCH.

[0979] S204: The UE determines each PUCCH resource in the PUCCH resource set based on the configuration of the PUCCH resource set. Specifically, in the NR R16 standard, one PUCCH resource set contains 16 PUCCH resources. Each PUCCH resource is determined based on the corresponding PUCCH format, the first symbol, the number of symbols, the physical resource block offset, and the cyclic shift index set for PUCCH transmission. The UE uses the index r PUCCH to indicate each PUCCH resource among the 16 PUCCH resources included in one PUCCH resource set. Here, 0 ≦ r PUCCH ≦ 15,

[0980]

Number

[0981] and N CCE is the number of control channel elements (CCEs) in the control resource set (CORESET) for PDCCH reception, and n CCE,0 is the index of the first CCE in the PDCCH, and Δ PRI is the value in the PUCCH resource indicator field in the DCI.

[0982]

Number

[0983] if it is, the UE determines that the PRB index for PUCCH transmission at the first mapping position is

[0984]

Number

[0985] and determines that the PRB index for PUCCH transmission at the second mapping position is

[0986]

Number

[0987] and determines that

[0988]

Number

[0989] is the number of RBs occupied by the BWP,

[0990]

Number

[0991] is the PRB offset, and N CS is the total number of initial cyclic shift indexes in the initial cyclic shift index set. The UE determines that the initial cyclic shift index for PUCCH transmission is r PUCCH mod N CS and decides that it is so.

[0992]

Number

[0993] If it is the case that, the UE determines that the PRB index for PUCCH transmission at the first mapping position is

[0994]

Number

[0995] and decides that the PRB index for PUCCH transmission at the second mapping position is

[0996]

Number

[0997] and decides that it is so. The UE determines that the initial cyclic shift index for PUCCH transmission is (r PUCCH -8) mod N CS and decides that it is so.

[0998] For example, when the parameter pucch-ResourceCommon is 1, it corresponds to the configuration of the PUCCH resource set whose index is 1 in Table 1. That is, the PUCCH resource set indicated by that row contains 16 PUCCH resources. Those 16 PUCCH resources use PUCCH format_0, the first symbol is 12, the number of symbols is 2, the PRB offset value is 0, the initial cyclic shift index set is {0, 4, 8}, and the total number of initial cyclic shift indices in the initial cyclic shift index set is N CS = 3.

[0999] r PUCCH = 0, 1,..., 7, the condition

[1000]

Number

[1001] is satisfied, and the corresponding 8 PUCCH resources are shown in Table 2. Each PUCCH resource is determined based on the physical resource block index and the initial cyclic shift index.

[1002]

Table 2

[1003] r PUCCH = 8, 9,..., 15, the condition

[1004]

Number

[1005] is satisfied, and the corresponding 8 PUCCH resources are shown in Table 3. Each PUCCH resource is determined based on the physical resource block index and the initial cyclic shift index.

[1006]

Table 3

[1007] FIG. 3 is a schematic diagram showing the time-frequency position of PUCCH resources according to the prior art. As shown in FIG. 3, based on the configuration of the PUCCH resource set whose index is 1 in Table 1, the time-domain resource position of the PUCCH resource occupies two symbols starting from the first symbol 12 in a time unit (slot). PUCCH resource r PUCCH =0, 1, 2, 8, 9, 10, the frequency-domain frequency hopping distance is

[1008]

Number

[1009] and for PUCCH resource r PUCCH =3, 4, 5, 11, 12, 13, the frequency-domain frequency hopping distance is

[1010]

Number

[1011] and for PUCCH resource r PUCCH =6, 7, 14, 15, the frequency-domain frequency hopping distance is

[1012]

Number

[1013] is.

[1014] S205: The base station transmits PDSCH to the UE.

[1015] S206: The UE performs PUCCH transmission based on the PDSCH. For example, the UE may provide HARQ-ACK information during PUCCH transmission.

[1016] The value of the PUCCH transmission power is related to coverage. Specifically, the larger the transmission power, the longer the transmission distance. As can be seen from FIG. 3, each PUCCH resource occupies only one PRB. Under the condition that the maximum transmission power and the power spectral density are limited, the transmission power of one PRB is relatively small, and therefore, the coverage is relatively small. As can be further seen from FIG. 3, the frequency domain frequency hopping distances in some PUCCH resources are different. For example, the frequency domain frequency hopping distance of PUCCH resources r PUCCH = 0, 1, 2, 8, 9, 10 is larger than the frequency domain frequency hopping distance of PUCCH resources r PUCCH = 6, 7, 14, 15. For PUCCH resources whose frequency domain position is farther from the edge of the BWP, the shorter the frequency domain frequency hopping distance, the smaller the frequency hopping gain. As a result, coverage degradation occurs to a certain extent. Therefore, how to relax the limitation of the frequency hopping gain of PUCCH resources and how to expand the coverage are urgent problems to be solved.

[1017] In the prior art, in order to improve the PUCCH transmission coverage, it has been proposed that each PUCCH resource may occupy a plurality of PRBs. When the constraint conditions of the maximum transmission power and the power spectral density are satisfied, the transmission power of a plurality of PRBs may be larger than the power of one PRB. Therefore, the PUCCH transmission coverage is improved. However, since each PUCCH resource may occupy a plurality of PRBs, for PUCCHs whose frequency domain position is farther from the edge of the BWP, the frequency hopping distance of the PUCCH becomes shorter, and the frequency hopping gain is more limited. As a result, the coverage degradation becomes more severe.

[1018] FIG. 4 is a schematic diagram showing the time-domain position of another PUCCH resource according to the prior art. As shown in FIG. 4, it is assumed that one PUCCH resource occupies two RBs. The frequency hopping distance of all PUCCH resources is

[1019]

Number

[1020] equal to. The 16 PUCCH resources have the same frequency-domain frequency hopping distance and the same frequency hopping gain, but the PUCCH resources may be fragmented. For example, when only PUCCH resource r PUCCH = 1 is used for transmission, there are some idle spectra remaining between the end of the BWP and the second mapping position of r PUCCH = 1, and spectral fragmentation may occur. Also, as can be seen from FIG. 4, r PUCCH = 0, 1, 2 are not at the ends on both sides of the BWP. Therefore, due to the time-domain position of the PUCCH resources in this method, the maximum frequency hopping gain is limited, and there is the most serious coverage degradation problem.

[1021] The technical problems to be solved in the embodiments of the present application may include the following. That is, in the embodiments of the present application, the frequency-domain position where the PUCCH resources are mapped changes in consecutive time units, so that the frequency-domain frequency hopping distance of all PUCCH resources can be made the same on average in the time dimension. In this way, the frequency hopping gain becomes the same on average in the time dimension. This can relax the limitation of the frequency hopping gain of the PUCCH resources and expand the coverage.

[1022] Based on the above description, in order to better understand the communication method and related apparatus provided in the present application, the network architecture to which the embodiments of the present application are applied will be described first below.

[1023] FIG. 5 is a schematic diagram showing a network architecture according to an embodiment of the present application. As shown in FIG. 5, the network architecture may include a network device 501 and a terminal device 502. The terminal device 502 may be connected to the network device 501 in a wireless manner and access the core network by using the network device 501. The terminal device 502 may be arranged at a fixed position or may be movable.

[1024] The network device 501 may be an entity for transmitting or receiving signals, or may be a device for communicating with the terminal device. This network device may be a base transceiver station (BTS) in a global system for mobile communications (GSM) or a code division multiple access (CDMA) system, or may be a Node B (NB) in a wideband code division multiple access (WCDMA) system, or may be an evolved Node B (eNB or eNodeB) in an LTE system, or may be a radio controller in a cloud radio access network (CRAN) scenario. Alternatively, the network device may be a relay node, an access point, an in-vehicle device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN network, etc. In the present embodiment of the present application, it is not limited thereto. The network device may be a device in a wireless network, for example, a radio access network (RAN) node that enables a terminal to access the wireless network. Currently, the RAN node is, for example, a Node B, a next-generation Node B gNB, a transmission and reception point (TRP), an evolved Node B (eNB), a home Node B, a baseband unit (BBU), or an access point (AP) in a Wi-Fi system. In the network structure, the network device may include a central unit (CU) node, or a distributed unit (DU) node, or a RAN device including the CU node and the DU node.

[1025] The terminal device 502 is an entity on the user side for receiving or transmitting signals, for example, a user device, an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile console, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus.

[1026] By way of example and not limitation, in the present embodiment of the present application, the terminal may alternatively be a wearable device. A wearable device, sometimes referred to as a wearable intelligent device, is a general term for a wearable device that is intelligently designed and developed for daily wear by using wearable technologies such as glasses, gloves, watches, clothing, and shoes. This wearable device is a portable device that can be directly worn on the body or incorporated into the user's clothing or accessories. A wearable device is not only a hardware device but also implements powerful functions through software support, data exchange, and cloud interaction. General wearable smart devices include, for example, fully equipped and large devices such as smartwatches or smart glasses that can implement complete or partial functions without relying on a smartphone, and devices such as various smart bands or smart jewelry for monitoring physical symptoms that focus only on one type of application function and need to cooperate with other devices such as smartphones. Alternatively, in the present embodiment of the present application, the terminal may be a terminal in an Internet of Things (IoT) system. The IoT is an important component of the future development of information technology and has the main technical feature of connecting things to a network by using communication technology to realize an intelligent network for the interconnection of people and machines and the interconnection of things and things. In the present embodiment of the present application, the IoT technology may realize large-scale connection, detailed coverage, and power saving of the terminal by using, for example, narrowband (NB) technology. Also, in the present embodiment of the present application, the terminal may further include sensors such as, for example, an intelligent printer, a train detector, or a gas station. The main functions of the terminal include (for some terminals) data collection, reception of control information and downlink data from network devices, transmission of electromagnetic waves, and uplink data transmission to network devices.

[1027] The technical solution in the present embodiment of this application can be applied to various communication systems, such as Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), LTE system, LTE Frequency Division Duplexing (FDD) system, LTE Time Division Duplexing (TDD) system, Universal Mobile Telecommunications System (UMTS), GSM Enhanced Data Rates for GSM Evolution (EDGE) system, and Worldwide Interoperability for Microwave Access (WiMAX) system, etc. The technical solution in the present embodiment of this application can be further applied to other communication systems, such as Public Land Mobile Network (PLMN) system, Long Term Evolution Advanced (LTE-A) system, Fifth Generation (5G) mobile communication system, New Radio (NR) system, Machine-to-Machine (M2M) communication system, or other future evolved communication systems. In the present embodiment of this application, it is not limited thereto.

[1028] In the present embodiment of this application, the terminal device or network device includes a hardware layer, an operating system layer operating above the hardware layer, and an application layer operating above the operating system layer. The hardware layer includes hardware such as a Central Processing Unit (CPU), a Memory Management Unit (MMU), and a memory (also called main memory). The operating system is any one or more types of computer operating systems that implement service processing through processing, such as Linux (Registered Trademark) operating system, Unix (Registered Trademark) operating system, Android (Registered Trademark) operating system, iOS (Registered Trademark) operating system, or Windows (Registered Trademark)It may be an operating system. The application layer includes applications such as a browser, an address book, word processing software, and instant messaging software. Also, if a program that records the code of the method provided in the embodiments of the present application can be executed to perform communication according to the method provided in the embodiments of the present application, the specific structure in the execution entity of the method provided in the embodiments of the present application is not particularly limited in the present embodiments of the present application. For example, the execution entity of the method provided in the embodiments of the present application may be a terminal device or a network device, or a functional module that is within the terminal device or the network device and can call and execute the program.

[1029] It should be noted that the quantity and types of terminals included in the network architecture shown in FIG. 5 are merely examples, and the present embodiments of the present application are not limited thereto. For example, the number of terminals communicating with the network device may include more or fewer. For simplicity, details are not described in the accompanying drawings. Also, in the network architecture shown in FIG. 5, the network device and the terminals are illustrated, but the scenarios of the present application are not limited to the network device and the terminals. For example, it may further include a core network node or a device configured to undertake virtualized network functions. This is obvious to those skilled in the art and details are not described in this specification.

[1030] With reference to the above network architecture, the communication method provided in the embodiments of the present application will be described below. FIG. 6 is a schematic flowchart showing a communication method according to an embodiment of the present application. The functions executed by the terminal device in this embodiment may alternatively be executed by a module (such as a chip, etc.) in the terminal device. The functions executed by the network device in the present application may alternatively be executed by a module (such as a chip, etc.) in the network device. As shown in FIG. 6, the present communication method may include the following steps.

[1031] Step S601: The network device transmits first indication information used to determine the frequency domain position where the PUCCH resource is mapped to the terminal device. Correspondingly, the terminal device receives the first indication information used to determine the frequency domain position where the PUCCH resource is mapped from the network device.

[1032] After receiving the first indication information from the network device, the terminal device determines the frequency domain position where the PUCCH resource is mapped based on the first indication information, and there may be the following two cases.

[1033] In the first case, the network device does not configure dedicated PUCCH resources for the terminal device. When the PUCCH resources of the terminal device are provided by using the parameter pucch-ResourceCommon, it can be understood that the first indication information may include SIB1 and DCI. SIB1 carries the parameter pucch-ResourceCommon. The parameter pucch-ResourceCommon is an indication field in the RRC message. The parameter hierarchy in 38.331 is SIB1 → ServingCellConfigCommonSIB → UplinkConfigCommonSIB → BWP-UplinkCommon → PUCCH-ConfigCommon → pucch-ResourceCommon. The value of the parameter pucch-ResourceCommon is one of 0 to 15. The terminal device determines a PUCCH resource set based on the parameter pucch-ResourceCommon. The value of the parameter pucch-ResourceCommon corresponds to the index value in Table 1, that is, the rows in Table 1 are determined as the configuration of the PUCCH resource set. The terminal device determines each PUCCH resource in the PUCCH resource set based on the configuration of the PUCCH resource set. The UE uses an index r PUCCH to indicate each PUCCH resource among the 16 PUCCH resources included in one PUCCH resource set. Here, 0 ≤ r PUCCH ≤ 15,

[1034]

Number

[1035] and N CCE is the number of control channel elements (CCEs) in the control resource set (CORESET) for PDCCH reception, and n CCE,0 is the index of the first CCE on the PDCCH, and Δ PRIis a value in the PUCCH resource indicator field in DCI.

[1036] The frequency domain position where the PUCCH resource is mapped includes the starting PRB index of the PUCCH resource at the first mapping position, the starting PRB index of the PUCCH resource at the second mapping position, and the initial cyclic shift index of the PUCCH resource. The frequency domain position where the PUCCH resource is mapped can satisfy any one of the following rules.

[1037] Rule 1:

[1038] Method 1: For PUCCH resource set indices from 0 to 15, based on Table 1,

[1039]

Number

[1040] if it is the case, the starting PRB index of the PUCCH resource at the first mapping position is

[1041]

Number

[1042] and the starting PRB index of the PUCCH resource at the second mapping position is

[1043]

Number

[1044] and the initial cyclic shift index of the PUCCH resource is r PUCCH mod N CS is.

[1045]

Number

[1046] If it is the case, the starting PRB index of the PUCCH resource at the first mapping position is

[1047] [Number]

[1048] and the starting PRB index of the PUCCH resource at the second mapping position is

[1049] [Number]

[1050] and the initial cyclic shift index of the PUCCH resource is (r PUCCH -8) mod N CS where

[1051] [Number]

[1052] is the PRB offset, r PUCCH is the index of the PUCCH resource, N CS is the total number of initial cyclic shift indices in the initial cyclic shift index set,

[1053] [Number]

[1054] is the number of PRBs occupied by the bandwidth part BWP, N is the number of PRBs occupied by the PUCCH resource, and N is a positive integer of 1 or more.

[1055] For example, assuming N = 1, that is, the number of RBs transmitted on each PUCCH is 1 and the parameter pucch-ResourceCommon = 1, the frequency domain position where the PUCCH resource is mapped is as shown in FIG. 3. As shown in FIG. 3, based on the configuration of the PUCCH resource set whose index is 1 in Table 1, the time domain resource position of the PUCCH resource occupies 2 symbols starting from the first symbol 12. The starting PRB index of the PUCCH resource r PUCCH = 0, 1, 2 at the first mapping position is PRB0, and the starting PRB index at the second mapping position is PRB

[1056]

Number

[1057] at the first mapping position is PRB PUCCH = 3, 4, 5 at the first mapping position is PRB1, and the starting PRB index at the second mapping position is PRB

[1058]

Number

[1059] at the first mapping position is PRB PUCCH = 6, 7 at the first mapping position is PRB2, and the starting PRB index at the second mapping position is PRB

[1060]

Number

[1061] at the first mapping position is PRB PUCCH = 8, 9, 10 at the first mapping position is PRB

[1062]

Number

[1063] and the starting PRB index at the second mapping position is PRB0, and the PUCCH resource r at the first mapping position PUCCH = 11, 12, 13, the starting PRB index is PRB

[1064]

Number

[1065] and the starting PRB index at the second mapping position is PRB1, and the PUCCH resource r at the first mapping position PUCCH = 14, 15, the starting PRB index is PRB

[1066]

Number

[1067] and the starting PRB index at the second mapping position is PRB2.

[1068] As another example, when N > 1, that is, when the number of RBs transmitted on each PUCCH is greater than 1, it is assumed that the parameter pucch-ResourceCommon is 1. FIG. 7 is a schematic diagram showing the time-frequency position of the PUCCH resource according to an embodiment of the present application. As shown in FIG. 7, based on the configuration of the PUCCH resource set whose index is 1 in Table 1, the time-domain resource position of the PUCCH resource occupies 2 symbols starting from the first symbol 12. The PUCCH resource r at the first mapping position PUCCH = 0, 1, 2, the starting PRB index is PRB0, and the starting PRB index at the second mapping position is PRB

[1069]

Number

[1070] is such that the starting PRB index for PUCCH resource r at the first mapping position PUCCH =3, 4, 5 is PRB N, and the starting PRB index at the second mapping position is PRB

[1071]

Number

[1072] is such that the starting PRB index for PUCCH resource r at the first mapping position PUCCH =6, 7 is PRB 2N, and the starting PRB index at the second mapping position is PRB

[1073]

Number

[1074] is such that the starting PRB index for PUCCH resource r at the first mapping position PUCCH =8, 9, 10 is PRB

[1075]

Number

[1076] is such that the starting PRB index at the second mapping position is PRB0, and the starting PRB index for PUCCH resource r at the first mapping position PUCCH =11, 12, 13 is PRB

[1077]

Number

[1078] and the starting PRB index at the second mapping position is PRB N, and the starting PRB indices of PUCCH resource r PUCCH = 14, 15 are PRB

[1079]

Number

[1080] and the starting PRB index at the second mapping position is PRB 2N.

[1081] It can be understood that the frequency domain positions where PUCCH resources are mapped, determined based on frequency division multiplexing in Mode 1, can reduce the possibility of different PUCCH resources overlapping in the frequency domain.

[1082] Furthermore, according to the regulatory constraints in various countries and regions, including effective isotropic radiated power (EIRP) constraints and / or power spectral density (PSD) constraints, the maximum number of PRBs occupied by the transmission resources of PUCCH format 0 / 1 / 4 varies according to the subcarrier spacing (SCS).

[1083] When the SCS is 120 kHz, the maximum number of PRBs occupied by the resources of PUCCH format 0 / 1 / 4 is 32.

[1084] When the SCS is 480 kHz, the maximum number of PRBs occupied by the resources of PUCCH format 0 / 1 / 4 is 8.

[1085] When the SCS is 960 kHz, the maximum number of PRBs occupied by the resources of PUCCH format 0 / 1 / 4 is 4.

[1086] Currently, for the 120 / 480 / 960 kHz SCS, the maximum number of PRBs occupied by the resources of PUCCH format 0 / 1 / 4 is the same, specifically 16.

[1087] For the 120 / 480 / 960 kHz SCS, since the maximum number of PRBs occupied by the resources of PUCCH format 0 / 1 / 4 is 16, there may be a shortage of RBs in various configurations in Table 1.

[1088] In the case of RB shortage, the frequency domain position where the PUCCH resource is mapped can be determined to be any one of Method 2 to Method 6.

[1089] Method 2: It is assumed that the PUCCH resource set index configured for the terminal device is 15, and the number of available RBs for the configured PUCCH format 0 / 1 / 4 is below the threshold. For example, the value of T is 3.

[1090] If it is assumed that the PUCCH resource set index configured for the terminal device is 15 and the number of available RBs N for the configured PUCCH format 0 / 1 / 4 is greater than the threshold T, it can be understood that some RBs in the PUCCH resource may exceed the maximum range of the initial uplink bandwidth part (UL BWP). For example, N = 4, and the first hop frequency domain resource index of r PUCCH = 0, 1, 2, 3 determined by using Method 1 is

[1091]

Number

[1092] is. Furthermore,

[1093]

Number

[1094] When it is PUCCH = 0, 1, 2, or 3, the first hop frequency region resource index is 100 to 103, which exceeds the UL BWP range and it is assumed that there are no available PUCCH resources. In other words, there is a shortage of RBs.

[1095] The number of available RBs for the configured PUCCH format 0 / 1 / 4 is restricted to be below a threshold, thereby avoiding the case where there are no available PUCCH resources, in other words, when there is a shortage of RBs. In a configuration where the PUCCH resource set index is 15, when the number of RBs occupied by the PUCCH resource is 2, the corresponding 16 PUCCH resources are explained by using Table (a) as an example.

[1096] [Table 4]

[1097] [Table 5]

[1098] In a configuration where the PUCCH resource set index is 15, when the number of RBs occupied by the PUCCH resource is 3, the corresponding 16 PUCCH resources are explained by using Table (b) as an example.

[1099] [Table 6]

[1100] [Table 7]

[1101] By using Method 2, determining the frequency domain position where the PUCCH resource is mapped can avoid the problem of RB shortage that occurs when the PUCCH resource set index configured for the terminal device is 15 and the number of RBs N occupied by the resources of PUCCH format 0 / 1 / 4 is configured to be relatively large.

[1266] For example, assume that the parameter pucch-ResourceCommon is 1. FIG. 8 is a schematic diagram showing the time-frequency position of another PUCCH resource according to an embodiment of the present application. As shown in FIG. 8, based on the configuration of the PUCCH resource set where the index is 1 in Table 1, the time-domain resource position of the PUCCH resource starts from the first symbol 12 and occupies two symbols. The start PRB index of the first PUCCH resource r PUCCH =0, 1, 2 is PRB 0, and the start PRB index at the second mapping position is PRB

[1278] and the starting PRB index at the second mapping position is PRB N.

[1279] In the second case, the network device configures dedicated PUCCH resources for the terminal device, which can be understood as the network device configuring dedicated PUCCH resources by using dedicated RRC signaling. The first indication information may include one or more PUCCH resources dedicated to the terminal device, and may further include a PUCCH frequency hopping indication indicating to the terminal device that it should perform frequency hopping. In one embodiment, the first indication information may be PUCCH-Config, and PUCCH-Config is used to configure dedicated PUCCH resources for the terminal device, and PUCCH-Config is an indication field in dedicated RRC signaling.

[1280] In the case of frequency hopping, the number of PRBs occupied by the PUCCH resource is N, and N is a positive integer greater than or equal to 1. The frequency domain position where the PUCCH resource is mapped may include the starting PRB index of the PUCCH resource at the first mapping position and the starting PRB index of the PUCCH resource at the second mapping position.

[1281] When the transmission of a PUCCH resource occupies one PRB, the starting PRB index of the PUCCH resource at the first mapping position may also be referred to as the PRB index of the PUCCH resource at the first mapping position, and the starting PRB index of the PUCCH resource at the second mapping position may also be referred to as the PRB index of the PUCCH resource at the second mapping position. In one embodiment, the PRB index of the PUCCH resource at the first mapping position may be represented by the first hop PRB, and the PRB index of the PUCCH resource at the second mapping position may be represented by the second hop PRB.

[1282] When the transmission of a PUCCH resource occupies multiple PRBs, in one embodiment, the starting PRB index of the PUCCH resource at the first mapping position may be represented by the first hop starting PRB, and the starting PRB index of the PUCCH resource at the second mapping position may be represented by the second hop starting PRB. In another embodiment, the ending PRB index of the PUCCH resource at the first mapping position may be represented by the first hop ending PRB, and the ending PRB index of the PUCCH resource at the second mapping position may be represented by the second hop ending PRB.

[1283] For example, FIG. 9 is a schematic diagram showing the time-frequency position of yet another PUCCH resource according to an embodiment of the present application. As shown in FIG. 9, the PRB index of the PUCCH resource at the first mapping position may be represented by the first hop PRB, and the PRB index of the PUCCH resource at the second mapping position may be represented by the second hop PRB. The PRB index of the PUCCH resource at the first mapping position is from PRB N to PRB 2N - 1, and the PRB index of the PUCCH resource at the second mapping position is PRB

[1284]

Number

[1285] or PRB

[1286] [Number]

[1287] is.

[1288] Optionally, the frequency domain position where the PUCCH resource is mapped satisfies Rule 2 only when any one of the following conditions is met.

[1289] Condition 1: N is greater than or equal to (or exceeds) a first threshold, and the first threshold is a positive integer greater than 1.

[1290] Condition 2: The bandwidth of the BWP is less than or equal to (or less than) a second threshold, and the second threshold is a positive integer. For example, when the subcarrier spacing (SCS) is 120K, the bandwidth of the BWP is less than X; when the SCS is 480K, the bandwidth of the BWP is less than X / 4; when the SCS is 960K, the bandwidth of the BWP is less than X / 8; or when the SCS is 1920K, the bandwidth of the BWP is less than X / 16. In one embodiment, X = 400. When the bandwidth of the BWP is less than 400, the frequency hopping gains of different PUCCH resources are significantly different. When the bandwidth of the BWP tends to be a larger value (e.g., exceeding 400), different PUCCH resources have different frequency hopping distances, but it can be understood that they can obtain the main frequency hopping gain and have little impact on coverage.

[1291] In this embodiment of the present application, the PUCCH resource can be understood as the PUCCH transmission resource in the standard specification. The first mapping position of the PUCCH resource can be understood as the first hop in the standard specification. It should be noted that the starting PRB index can be understood as the lowest PRB index, and the ending PRB index can be understood as the highest PRB index. For example, when the PRB index corresponding to the PUCCH resource is from PRB 0 to PRB n-1, the starting PRB index is PRB 0, and the ending PRB index is PRB n-1. This is described in a unified manner in this specification and will not be elaborated later.

[1292] Step S602: The terminal device transmits information to the network device in the first period by using the PUCCH resource, and the frequency domain positions where the PUCCH resource is mapped in at least two consecutive time units in the first period are different.

[1293] After determining the frequency domain position where the PUCCH resource is mapped based on the first indication information, the terminal device can transmit information to the network device within the first period by using the PUCCH resource. In at least two consecutive time units in the first period, the frequency domain positions where the PUCCH resource is mapped change with the time unit. The information may be the uplink control information of the PUCCH resource and may include HARQ-ACK information, SR information, CSI, etc.

[1294] It should be noted that the first mapping position and the second mapping position included in the frequency domain position where the PUCCH resource is mapped are at different time domain positions in the same time unit. The time unit can be a frame, a subframe, a slot, a symbol, etc. For example, the first mapping position and the second mapping position are respectively on two different symbols in a slot.

[1295] Optionally, the frequency domain positions where PUCCH resources are mapped in at least two consecutive time units in the first period are different only if any one of the following conditions is satisfied.

[1296] Condition 1: N is greater than or equal to (or exceeds) a first threshold, and the first threshold is a positive integer greater than 1.

[1297] Condition 2: The bandwidth of the BWP is less than or equal to (or less than) a second threshold, and the second threshold is a positive integer. For example, when the subcarrier spacing (SCS) is 120K, the bandwidth of the BWP is less than X; when the SCS is 480K, the bandwidth of the BWP is less than X / 4; when the SCS is 960K, the bandwidth of the BWP is less than X / 8; or when the SCS is 1920K, the bandwidth of the BWP is less than X / 16. In one embodiment, X = 400.

[1298] The start time unit in at least two consecutive time units can be determined in any one of the following ways.

[1299] Way 1: The start time unit is determined according to the default specification of the protocol without signaling indication.

[1300] Way 2: The terminal device receives second indication information from the network device and determines the start time unit based on the second indication information. The second indication information may indicate that the start time unit is the time unit when the terminal device first uses the PUCCH resource. Alternatively, the second indication information may include a time period offset indicating that the start time unit is the time unit obtained by adding the time period offset to the time unit when the terminal device receives the second indication information. For example, the terminal device receives the second indication information in slot 1, and the time period offset is 3. In this case, the start time unit is slot 4. Alternatively, the second indication information may include a time unit index value indicating that the start time unit is the time unit corresponding to the time unit index value.

[1301] The frequency domain positions to which PUCCH resources are mapped are in at least two consecutive time units and change with the time units starting from the start time unit. The details are as follows.

[1302] In step S601, for the frequency domain positions to which PUCCH resources are mapped, which are determined according to rule 1 in the first case, the fact that the frequency domain positions to which PUCCH resources are mapped are different in at least two consecutive time units may satisfy any one of the following implementations.

[1303] In the first implementation, the start PRB index of the PUCCH resource at the first mapping position and the start PRB index of the PUCCH resource at the second mapping position are periodically shifted by N PRBs from both sides of the BWP to the middle of the BWP. Specifically, in at least two consecutive time units,

[1304]

Number

[1305] If it is, the start PRB index of the PUCCH resource at the first mapping position is periodically shifted by N PRBs in ascending order of the PRB index, and the start PRB index of the PUCCH resource at the second mapping position is periodically shifted by N PRBs in descending order of the PRB index, or

[1306]

Number

[1307] When it is the case, the starting PRB index of the PUCCH resource at the first mapping position is periodically shifted by only N PRBs in descending order of the PRB index, and the starting PRB index of the PUCCH resource at the second mapping position is periodically shifted by only N PRBs in ascending order of the PRB index.

[1308] For example, FIGS. 10A to 10C are schematic diagrams showing different frequency region positions to which PUCCH resources are mapped according to embodiments of the present application. As shown in FIGS. 10A to 10C, in the starting time unit (the first time unit), with respect to the frequency region position to which the PUCCH resource shown in FIG. 7 is mapped, the frequency region position to which the PUCCH resource is mapped is different starting from the first time unit in consecutive time units. As an example for explanation, PUCCH resources r PUCCH = 0, 1, 2 are used. In the first time unit, the second time unit, and the third time unit, the starting PRB indices of the PUCCH resources r PUCCH = 0, 1, 2 at the first mapping position are PRB 0, PRB N, and PRB 2N, respectively, and the starting PRB indices of the PUCCH resources r PUCCH = 0, 1, 2 at the second mapping position are PRB

Number

[1332] is. After these three time units, the time-domain average value of all PUCCH resource frequency hopping distances is,

[1333]

Number

[1334] is.

[1335] The time-domain change period of the PUCCH resource frequency hopping distance is N CSIt should be noted that it can be determined based on this. According to the configuration of Table 1, for example, when N CS = 2, the time-domain change period of the PUCCH resource frequency hopping distance is a period of 4-hour units, and when N CS = 3, the time-domain change period of the PUCCH resource frequency hopping distance is a period of 3-hour units, and when N CS = 4, the time-domain change period of the PUCCH resource frequency hopping distance is a period of 2-hour units. FIGS. 10A to 10C are examples described by using the frequency-domain position where the PUCCH resource in FIG. 7 is mapped as the start time unit. FIG. 7 shows the frequency-domain position where the PUCCH resource is mapped, which is determined based on the configuration of the PUCCH resource set with index 1 in Table 1, and N CS = 3. Therefore, the time-domain change period of FIGS. 10A to 10C is a period of 3-hour units. The following embodiments are the same and will be described in a unified manner in this specification. Details will not be described hereinafter.

[1336] In the second implementation, the start PRB index of the PUCCH resource at the first mapping position and the start PRB index of the PUCCH resource at the second mapping position are periodically shifted by N PRBs from the middle of the BWP to both sides of the BWP.
