Description

Technical Field

[0001] [Cross - Reference to Related Applications] This application claims priority to Chinese Patent Application No. 202110507949.0, titled "INFORMATION TRANSMISSION METHOD AND APPARATUS", filed with the China National Intellectual Property Administration on May 10, 2021, and incorporates its entire content by reference.

[0002] [Technical Field] This application relates to the field of communications, and more specifically, to an information transmission method and apparatus.

Background Art

[0003] Terminal devices with different capabilities have different requirements for a mobile communication system. To meet requirements such as low cost and long standby time, generally, a low - capability terminal device supports a smaller channel bandwidth than that of a normal terminal device. For example, in frequency range 1 of a new radio (NR) system, an enhanced mobile broadband (eMBB) terminal device generally supports a maximum channel bandwidth of 100 MHz. However, a low - capability terminal device may support a maximum channel bandwidth of 5 MHz, 20 MHz, or 40 MHz. By reducing the channel bandwidth, the complexity and cost of the terminal device can be reduced.

[0004] Terminal devices with different capabilities coexist in the same communication system. Therefore, how to better support the coexistence of these terminal devices has become an urgent technical problem to be solved.

Summary of the Invention

[0005] This application provides an information transmission method and apparatus for avoiding resource fragmentation, reducing restrictions on resource scheduling, and improving the flexibility of resource allocation.

[0006] According to the first aspect, an information transmission method is provided. The method includes the following. The terminal device determines the number of initial cyclic shift indexes included in the target offset parameter, uplink control channel resource index, physical resource block offset parameter, and initial cyclic shift index set. The terminal device determines a resource block index for uplink control channel transmission based on the number of initial cyclic shift indexes included in the target offset parameter, uplink control channel resource index, physical resource block offset parameter, and initial cyclic shift index set. The terminal device transmits uplink control information to the network device on a resource related to the resource block index.

[0007] According to the information transmission method in this embodiment of this application, the terminal device determines a resource block index for uplink control channel transmission based on the number of initial cyclic shift indexes included in the target offset parameter, uplink control channel resource index, physical resource block offset parameter, and initial cyclic shift index set. The resource related to the resource block index does not cause resource fragmentation of other terminal devices and does not cause the available resources of other terminal devices to be divided into several fragmented frequency domain resource blocks. This does not limit the resource scheduling of other terminal devices. According to the information transmission method in this application, terminal devices with different capabilities can coexist better in the same communication system.

[0008] Referring to the first aspect, in some implementation manners of the first aspect, the uplink control information is transmitted by frequency hopping. The terminal device determining the resource block index includes the following. The terminal device determines a first resource block index corresponding to the p-th hop of the frequency hopping transmission of the uplink control information based on the target offset parameter, the uplink control channel resource index, the physical resource block offset parameter, and the number of initial cyclic shift indexes included in the initial cyclic shift index set, where p is a positive integer, and / or the terminal device determines a second resource block index corresponding to the q-th hop of the frequency hopping transmission of the uplink control channel data based on the target offset parameter, the uplink control channel resource index, the physical resource block offset parameter, the number of initial cyclic shift indexes included in the initial cyclic shift index set, and the first frequency range, where q is a positive integer. The resource related to the resource block index is within the first frequency range.

[0009] The information transmission method in this embodiment of this application may be applied to uplink control information transmission in a scenario with frequency hopping, or may also be applied to uplink control information transmission in a scenario without frequency hopping. It should be noted that, for example, a scenario with frequency hopping includes a p-th hop and a q-th hop. The target offset parameter may include a first sub-offset parameter and a second sub-offset parameter. The first sub-offset parameter and the second sub-offset parameter may be used to determine the positions of the physical uplink control channel resources corresponding to the p-th hop and the q-th hop respectively, and may also be referred to as a first sub-frequency region resource and a second sub-frequency region resource. Then, the first terminal device transmits uplink control information by using the first sub-frequency region resource and the second sub-frequency region resource. The first sub-frequency region resource and the second sub-frequency region resource do not limit resource scheduling within the available frequency range of other terminal devices. This reduces the limitation on the resource scheduling of other terminal devices and improves the flexibility of resource allocation.

[0010] It should be noted that the first frequency range is larger than the maximum channel bandwidth supported by the first terminal device.

[0011] Referring to the first aspect, in some implementation manners of the first aspect, the target offset parameter includes a first sub-offset parameter and a second sub-offset parameter. The first sub-offset parameter is used to determine a first resource block index. The second sub-offset parameter is used to determine a second resource block index.

[0012] In this implementation method, it should be noted that the terminal device may further adjust the target offset parameter based on the number of uplink control channel resources multiplexed by each resource block in the uplink transmission of other terminal devices having resource contention with the terminal device, and the number of cyclic shifts corresponding to the uplink control channel resource set. This is to avoid the case where the resources related to the resource block index conflict with the resources used by other terminal devices to transmit uplink control information. For example, the target offset parameter may be adjusted such that the resources related to the resource block index are allocated to a frequency position adjacent to the resources used by other terminal devices to transmit uplink control information.

[0013] It should be noted that the first sub-offset parameter and the second sub-offset parameter may be the same or different.

[0014] In a possible implementation method, the first sub-offset parameter and the second sub-offset parameter are determined by the first terminal device based on the first configuration information transmitted by the network device.

[0015] In another possible implementation method, the first sub-offset parameter is determined by the first terminal device based on the first configuration information. The second sub-offset parameter (i.e., D2) is determined by the first terminal device based on the first sub-offset parameter (i.e., D1) and the number of resource blocks included in the first frequency range (i.e., N size ).

[0016] By way of example and not limitation, the second sub-offset parameter D2 may be determined as D2 = N size + D1 - N BWP size BWP size where Nis the number of resource blocks included in the second frequency range.

[0017] Referring to the first aspect, in some implementation manners of the first aspect, p = 1 and q = 2, or p = 2 and q = 1.

[0018] Referring to the first aspect, in some implementation manners of the first aspect, the number of initial cyclic shift indexes included in the first resource block index, target offset parameter, uplink control channel resource index, physical resource block offset parameter, and initial cyclic shift index set satisfies the following correspondence.

Number

[0019] X1 is the first resource block index, RB BWP offset is the physical resource block offset parameter, r PUCCH is the uplink control channel resource index, N CS is the number of initial cyclic shift indexes included in the initial cyclic shift index set, D is the target offset parameter, D1 is the first sub-offset parameter used to determine the first resource block index, floor(r PUCCH / 8) indicates the floor of the result of r PUCCH / 8,

Number

[0020] Referring to the first aspect, in some implementation manners of the first aspect, the number of initial cyclic shift indexes included in the second resource block index, target offset parameter, uplink control channel resource index, physical resource block offset parameter, and initial cyclic shift index set satisfies the following corresponding relationship.

Number

[0021] X2 is the second resource block index, and N size is the number of resource blocks included in the first frequency range, and N BWP size is the number of resource blocks included in the second frequency range, and the second frequency range is less than or equal to the maximum channel bandwidth supported by the terminal device, RB BWP offset is the physical resource block offset parameter, and r PUCCH is the uplink control channel resource index, and N CS is the number of initial cyclic shift indexes included in the initial cyclic shift index set, D is the target offset parameter, and D2 is the second sub-offset parameter used to determine the second resource block index.

Number

[0022] In this implementation method, when the first sub-offset parameter is the same as the second sub-offset parameter, both the first sub-offset parameter and the second sub-offset parameter may be represented by the target offset parameter D. When the first sub-offset parameter is different from the second sub-offset parameter, the first sub-offset parameter and the second sub-offset parameter may be represented by D1 and D2 respectively. Alternatively, when the first sub-offset parameter D1 is represented by the target offset parameter D, the second sub-offset parameter may correspondingly be D2 = N size + D1 - N BWP size as represented. N BWP size is the number of resource blocks included in the second frequency range. The second frequency range is less than or equal to the channel bandwidth supported by the terminal device.

[0023] The method for determining the target offset parameter includes, but is not limited to, the following several methods. It should be noted that: (1) The terminal device determines the target offset parameter based on the first position and the second position. The first position is the position of the y-th resource block index within the first frequency range, and the second position is the position of the resource block where the resource block index is z and within the second frequency range. y and z are non-negative integers. The first frequency range is larger than the maximum channel bandwidth supported by the terminal device, and the second frequency range is less than or equal to the maximum channel bandwidth supported by the terminal device. Optionally, y and z may be the same. For example, y = z = 0 may be possible. (2) The terminal device determines the target offset parameter based on the first information, and the first information is received by the terminal device from the network device. For example, the first information is the master information block (MIB), system information block 1 (SIB 1), a field within SIB 1, the downlink control information for scheduling the PDSCH carrying SIB 1, or a field within the downlink control information for scheduling the PDSCH carrying SIB 1. (3) The target offset parameter is a predefined parameter. For example, the terminal device determines the target offset parameter in a predefined manner. The target offset parameter may be a predefined value. (4) The terminal device (which may also be called terminal device #1) determines the target offset parameter according to a predefined rule. For example, based on the frequency position occupied by the PUCCH resource set configured by another terminal device (which may also be called terminal device #2) having resource contention (an example of a predefined rule), the terminal device determines the target offset parameter, so that the frequency domain resource of the PUCCH of terminal device #1 is at a frequency position adjacent to the frequency domain resource of the PUCCH of terminal device #2.

[0024] Referring to the first aspect, in some implementation manners of the first aspect, the value of the target offset parameter is an integer less than 0. Alternatively, the value of the target offset parameter is an integer multiple of K, where K = 2, 3, or 4.

[0025] Referring to the first aspect, in some implementation manners of the first aspect, the terminal device transmits uplink control information without frequency hopping on the resource related to the resource block index.

[0026] Referring to the first aspect, in some implementation manners of the first aspect, before the terminal device determines the target offset parameter, the method further includes the following. The terminal device determines that the subcarrier spacing S corresponding to the terminal device and the number L of symbols of the uplink control channel resource satisfy a first preset condition.

[0027] By way of example and not limitation, the first pre-set condition may be one or more of the following conditions. (1) The minimum value of L is 4 or more. (2) The minimum value of L is determined based on S. (3) The value of L is within a first range of values, and when the value of L is within the first range of values, the uplink control channel is transmitted without frequency hopping, or the uplink control channel is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the first range of values may include {2, 4, 10}. (4) The value of L is within a second range of values, and when the value of L is within the second range of values, the uplink control channel is transmitted with frequency hopping and frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the second range of values may include {14}. (5) The value of S is within a third range of values, and when the value of S is within the third range of values, the uplink control channel is transmitted without frequency hopping, or the uplink control channel is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the third range of values may include 15 kHz, 30 kHz, 60 kHz or a value greater than 60 kHz. (6) The value of S is within a fourth range of values, and when the value of S is within the fourth range of values, the uplink control channel can be transmitted with frequency hopping and frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the fourth range of values may include 15 kHz, 30 kHz or 60 kHz.

[0028] In this implementation method, only when the subcarrier interval S and / or the number L of symbols used for uplink control channel transmission satisfy the first preset condition, the terminal device performs frequency hopping outside the second frequency range, or when S and L do not satisfy the first preset condition, the terminal device does not perform frequency hopping outside the second frequency range. In other words, the terminal device performs frequency hopping only within the second frequency range. This reduces the impact of frequency tuning (or retuning) time on the performance of the frequency domain resources corresponding to the terminal device with a small number L of symbols.

[0029] According to a second aspect, an information transmission method is provided. The method includes the following. A first terminal device (corresponding to the above terminal device) receives first configuration information. The first configuration information instructs the first terminal device to transmit uplink control information by using at least one first frequency domain resource. The first frequency domain resource is within the first frequency range. The first terminal device transmits uplink control information based on the first configuration information.

[0030] It should be noted that before the first terminal device receives the first configuration information, the method further includes the following. The first terminal device receives second configuration information. The second configuration information indicates a second frequency range allocated to the first terminal device by the network device. The second frequency range includes at least one second frequency domain resource. The second frequency domain resource is used for the first terminal device to transmit uplink control information. The second frequency domain resource is within a third frequency domain range allocated to a second terminal device (corresponding to another terminal device having a resource conflict with the above terminal device) by the network device. It should be noted that the first frequency domain resource is outside the third frequency domain range. Alternatively, the first frequency domain resource is located at the edge of the third frequency domain range.

[0031] In a possible implementation manner, the first frequency domain resource may be located at both ends of the carrier, or may be adjacent to the resource (which may be referred to as the third frequency domain resource) used for transmitting uplink control information by the second terminal device.

[0032] In a possible implementation manner, the uplink control information is used by the terminal device to access the network device. For example, the uplink control information may be a hybrid automatic repeat request message fed back by the terminal device for a contention resolution message transmitted by the network device in a random access process.

[0033] According to the information transmission method in this embodiment of this application, the second frequency domain resource determined based on the second configuration information by the first terminal device and used for transmitting uplink control information belongs to the third frequency domain range allocated by the network device to the second terminal device. The second frequency domain resource causes frequency domain fragmentation within the third frequency domain range, and the frequency domain resource is divided into several fragmented frequency domain resources. This limits the resource scheduling of the second terminal device. Based on this, the first terminal device may determine the first frequency domain resource used for transmitting uplink control information based on the first configuration information. The first frequency domain resource is outside the third frequency domain range. Alternatively, the first frequency domain resource is located at the edge part of the third frequency domain range. The first frequency domain resource does not limit the use of resources within the third frequency domain range of the second terminal. This improves the flexibility of resource scheduling.

[0034] It should be noted that the first frequency range is larger than the maximum channel bandwidth supported by the first terminal. The second frequency range is less than or equal to the maximum channel bandwidth supported by the first terminal. The third frequency range is less than or equal to the maximum channel bandwidth supported by the second terminal.

[0035] Referring to the second aspect, in some implementation manners of the second aspect, the first configuration information specifically indicates a target offset parameter. The target offset parameter is an offset parameter between the first frequency domain resource and the second frequency domain resource.

[0036] According to the information transmission method in this embodiment of this application, the first terminal device determines an offset parameter between the first frequency domain resource and the second frequency domain resource based on the first configuration information, determines the position of the first frequency domain resource based on the target offset parameter and the second frequency domain resource, and then may transmit uplink control information by using the first frequency domain resource. This reduces the restrictions on resource scheduling of the second terminal device and improves the flexibility of resource allocation.

[0037] Referring to the second aspect, in some implementation manners of the second aspect, in a scenario where uplink control information is transmitted by frequency hopping, the target offset parameter includes a first sub-offset parameter and a second sub-offset parameter. The first frequency domain resource includes a first sub-frequency domain resource and a second sub-frequency domain resource. The method includes the following. The first terminal device determines the first sub-offset parameter and the second sub-offset parameter. The first terminal device determines the first sub-frequency domain resource and the second sub-frequency domain resource based on the first sub-offset parameter and the second sub-offset parameter respectively. The first sub-frequency domain resource and the second sub-frequency domain resource are outside the third frequency domain range. Alternatively, the first sub-frequency domain resource and the second sub-frequency domain resource are located at the edge portion of the third frequency domain range.

[0038] The information transmission method in this embodiment of this application may be applied to uplink control information transmission in a scenario with frequency hopping, or may also be applied to uplink control information transmission in a scenario without frequency hopping. It should be noted that, for example, a scenario with frequency hopping includes a first hop and a second hop. The target offset parameter may include a first sub-offset parameter and a second sub-offset parameter. The first sub-offset parameter and the second sub-offset parameter may be used to determine the positions of the physical uplink control channel resources corresponding to the first hop and the second hop respectively, that is, the positions of the first sub-frequency region resource and the second sub-frequency region resource. Then, the first terminal device transmits uplink control information by using the first sub-frequency region resource and the second sub-frequency region resource. The first sub-frequency region resource and the second sub-frequency region resource no longer limit resource scheduling within the third frequency range. This reduces the limitation on the resource scheduling of the second terminal device and improves the flexibility of resource allocation.

[0039] Referring to the second aspect, in some implementation manners of the second aspect, the first configuration information includes the number of RBs included in the first frequency range and the indication information of the first sub-offset parameter. The first sub-frequency region resource and the second sub-frequency region resource are within the first frequency range. The method includes the following. The first terminal device determines the first sub-offset parameter based on the first configuration information. The first terminal device determines the second sub-offset parameter based on the first sub-offset parameter and the number of RBs included in the first frequency region range. The first terminal device determines the first sub-frequency region resource and the second sub-frequency region resource based on the first sub-offset parameter and the second sub-offset parameter respectively. The first terminal device transmits uplink control information by using the first sub-frequency region resource and the second sub-frequency region resource.

[0040] It should be noted that the first sub-offset parameter and the second sub-offset parameter may be the same or different.

[0041] Optionally, if the first sub-offset parameter is the same as the second sub-offset parameter, only one offset parameter may be used in the instruction to save resources.

[0042] In a possible implementation, the first sub-offset parameter and the second sub-offset parameter are determined by the first terminal device based on the first configuration information.

[0043] In another possible implementation, the first sub-offset parameter is determined by the first terminal device based on the first configuration information. The second sub-offset parameter (i.e., D2) is determined by the first terminal device based on the first sub-offset parameter (i.e., D1) and the number of resource blocks included in the first frequency range (i.e., N size ).

[0044] By way of example and not limitation, the second sub-offset parameter D2 may be determined as D2 = N size + D1 - N BWP size . N BWP size is the number of resource blocks included in the second frequency range.

[0045] In a possible implementation, the first terminal device may determine a resource block index corresponding to the first sub-frequency region resource (corresponding to the first resource block index) (denoted as X1) based on the target offset parameter according to the following formula.

Equation

[0046] X1 is the first resource block index, RB BWP offset is the physical resource block offset parameter, r PUCCH is the uplink control channel resource index, N CS is the number of initial cyclic shift indices included in the initial cyclic shift index set, D is the target offset parameter, D1 is the first sub-offset parameter, floor(r PUCCH / 8) represents the floor of r PUCCH / 8,

Number

[0047] In a possible implementation manner, the first terminal device may determine a resource block index (corresponding to the second resource block index, denoted as X2) corresponding to the second sub-frequency region resource based on the target offset parameter according to the following formula.

Number

[0048] X2 is the second resource block index, N size is the number of resource blocks included in the first frequency range, N BWP size is the number of resource blocks included in the second frequency range, and the second frequency range is below the maximum channel bandwidth supported by the terminal device, RB BWP offset is the physical resource block offset parameter, r PUCCH is the uplink control channel resource index, N CSis the number of initial cyclic shift indexes included in the initial cyclic shift index set, D is the target offset parameter, D2 is the second sub-offset parameter used to determine the second resource block index,

Number

[0049] Referring to the second aspect, in some implementation manners of the second aspect, the first configuration information includes indication information of the first sub-offset parameter and indication information of the second sub-offset parameter. For the first terminal device to determine the first sub-frequency domain resource and the second sub-frequency domain resource based on the first sub-offset parameter and the second sub-offset parameter respectively includes the following. The first terminal device determines the first sub-offset parameter and the second sub-offset parameter based on the first configuration information. The first terminal device determines the first sub-frequency domain resource and the second sub-frequency domain resource based on the first sub-offset parameter and the second sub-offset parameter respectively. The first terminal device transmits uplink control information by using the first sub-frequency domain resource and the second sub-frequency domain resource.

[0050] In this implementation method, the first sub-offset parameter and the second sub-offset parameter may be the same or different. When the first sub-offset parameter is different from the second sub-offset parameter, the first configuration information includes the indication information of the first sub-offset parameter and the indication information of the second sub-offset parameter. The first terminal device determines the first sub-offset parameter and the second sub-offset parameter respectively based on the indication information of the first sub-offset parameter and the indication information of the second sub-offset parameter, and then determines the first sub-frequency region resource and the second sub-frequency region resource based on the first sub-offset parameter and the second sub-offset parameter. Then, the first terminal device transmits uplink control information by using the first sub-frequency region resource and the second sub-frequency region resource. The first sub-frequency region resource and the second sub-frequency region resource no longer limit resource scheduling within the third frequency range. This reduces the restriction on the resource scheduling of the second terminal device and improves the flexibility of resource allocation.

[0051] Optionally, when the first sub-offset parameter is the same as the second sub-offset parameter, only one piece of indication information may be used for the indication to reduce the resource overhead.

[0052] Referring to the second aspect, in some implementation manners of the second aspect, before the first terminal device determines the target offset parameter, the method further includes the following. The first terminal device determines a first parameter. The first parameter is used to determine the target offset parameter. The first parameter is related to the number of uplink control channel resources multiplexed by each resource block in uplink transmission, or the number of cyclic shifts corresponding to the uplink control channel resource set. The first terminal device determining the target offset parameter includes the following. The first terminal device determines the target offset parameter based on the first parameter.

[0053] In this implementation manner, the first terminal device may further adjust the target offset parameter based on the number of uplink control channel resources multiplexed by each resource block in uplink transmission, or the number of cyclic shifts corresponding to the uplink control channel resource set, and then determine the first frequency domain resource based on the target offset parameter. This avoids competition between the first frequency domain resource and the resources (which may be referred to as the third frequency domain resources) used by the second terminal device to transmit uplink control information and within the third frequency range. For example, the first frequency domain resource may be allocated to a frequency position adjacent to the third frequency domain resource based on the first parameter.

[0054] Referring to the second aspect, in some implementation manners of the second aspect, before the first terminal device determines the target offset parameter, the method further includes the following. The first terminal device determines that the subcarrier spacing S corresponding to the first terminal device and the number L of symbols used for uplink control channel transmission satisfy a first preset condition.

[0055] By way of example and not limitation, the first preset condition may be one or more of the following conditions. (1) The minimum value of L is 4 or more. (2) The minimum value of L is determined based on S. (3) The value of L is within a first range of values, and when the value of L is within the first range of values, the uplink control channel is transmitted without frequency hopping, or the uplink control channel is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the first range of values may include {2, 4, 10}. (4) The value of L is within a second range of values, and when the value of L is within the second range of values, the uplink control channel is transmitted with frequency hopping and frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the second range of values may include {14}. (5) The value of S is within a third range of values, and when the value of S is within the third range of values, the uplink control channel is transmitted without frequency hopping, or the uplink control channel is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the third range of values may include 15 kHz, 30 kHz, 60 kHz or a value greater than 60 kHz. (6) The value of S is within a fourth range of values, and when the value of S is within the fourth range of values, the uplink control channel can be transmitted with frequency hopping and frequency tuning is required between two adjacent hops of the frequency hopping transmission. By way of example and not limitation, the fourth range of values may include 15 kHz, 30 kHz or 60 kHz.

[0056] In this implementation method, the first terminal device performs frequency hopping outside the second frequency range only when the sub-carrier interval S and / or the number L of symbols used for uplink control channel transmission satisfy a first preset condition. When S and L do not satisfy the first preset condition, the first terminal device does not perform frequency hopping outside the second frequency range. In other words, the first terminal device performs frequency hopping only within the second frequency range. This reduces the impact of the readjustment time on the performance of the first frequency region resource corresponding to the first terminal device having a small number L of symbols.

[0057] According to a third aspect, an information transmission method is provided. The method includes the following. A terminal device determines a subcarrier spacing S and / or the number L of symbols used for uplink control channel transmission. L and / or S satisfy at least one of the following conditions: (1) the minimum value of L is 4 or more; (2) the minimum value of L is determined based on S; (3) the value of L is within a first value range, and the uplink control channel is transmitted without frequency hopping within the first value range, or the uplink control channel is transmitted with frequency hopping within the first value range and no frequency tuning is required between two adjacent hops of the frequency hopping transmission; (4) the value of L is within a second value range, and the uplink control channel is transmitted with frequency hopping within the second value range and frequency tuning is required between two adjacent hops of the frequency hopping transmission; (5) the value of S is within a third value range, and the uplink control channel is transmitted without frequency hopping within the third value range, or the uplink control channel is transmitted with frequency hopping within the third value range and no frequency tuning is required between two adjacent hops of the frequency hopping transmission; or (6) the value of S is within a fourth value range, and the uplink control channel can be transmitted with frequency hopping within the fourth value range and frequency tuning is required between two adjacent hops of the frequency hopping transmission. When the above conditions are satisfied, the terminal device transmits the uplink control channel.

[0058] In a possible implementation, when condition (1) is satisfied, the two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. For example, when L = 10, the two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. When condition (2) is satisfied, the two hops of the PUCCH transmission sent by the terminal device are outside or within the second frequency range. For example, when S = 15 kHz, the minimum value of L is 10. Specifically, the two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. For example, when S = 30 kHz, the minimum value of L is 14. Specifically, the two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. For example, when S = 60 kHz, the PUCCH sent by the terminal device is transmitted without frequency hopping, or the PUCCH is transmitted with frequency hopping, and two adjacent hops of the frequency hopping transmission are within the second frequency range. When condition (3) is satisfied, the PUCCH sent by the terminal device is transmitted without frequency hopping, or is transmitted with frequency hopping, and the two hops are within the second frequency range. The range of the first value may also be that L is 4 or less. When condition (4) is satisfied, the two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. The range of the second value may also be that L is greater than 4 or L is 10 or more. When condition (5) is satisfied, the PUCCH sent by the terminal device is transmitted without frequency hopping, or is transmitted with frequency hopping, and the two hops are within the second frequency range. The range of the third value may also be that S is 60 kHz or more, or S is greater than 30 kHz. When condition (6) is satisfied, the two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. The range of the fourth value may also be that S is 30 kHz or less.

[0059] It should be noted that conditions (1) to (6) may be combined with each other. For example, condition (3) may be used together with condition (5). Specifically, when the value of L is within the range of the first value and S is within the range of the third value, PUCCH is transmitted without frequency hopping, or PUCCH is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the frequency hopping transmission. For example, condition (4) may be used together with condition (6). Specifically, when the value of L is within the range of the second value and S is within the range of the fourth value, PUCCH can be transmitted with frequency hopping and frequency tuning is required between two adjacent hops of the frequency hopping transmission.

[0060] In a possible implementation, the terminal device receives second information transmitted by the network device. The second information may indicate whether the uplink control information of the terminal device is transmitted with frequency hopping.

For example, the range of the first type of values may be that S = 15 kHz and L = 2 or 4, or S = 30 kHz or 60 kHz and L = 2, 4 or 10, or S is greater than 60 kHz. The frequency range in which the uplink control channel is transmitted with frequency hopping and frequency tuning is required between two adjacent hops of the transmission by frequency hopping may be referred to as the range of the second type of values.

When this is the case, the network device receives the uplink control information transmitted by the terminal device.

[0079] In a possible implementation manner, when condition (1) is satisfied, the network device may be configured such that two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. For example, when L = 10, the network device may be configured such that two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. When condition (2) is satisfied, the network device may be configured such that two hops of the PUCCH transmission sent by the terminal device are outside or within the second frequency range. For example, when S = 15 kHz, the minimum value of L is 10. Specifically, the network device may be configured such that two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. For example, when S = 30 kHz, the minimum value of L is 14. Specifically, the network device may be configured such that two hops of the PUCCH transmission sent by the terminal device are outside the second frequency range. For example, when S = 60 kHz, the network device may be configured such that the PUCCH sent by the terminal device is transmitted without frequency hopping, or is transmitted with frequency hopping, and two adjacent hops of the transmission by frequency hopping are within the second frequency range. When condition (3) is satisfied, the network device may be configured such that the PUCCH sent by the terminal device is transmitted without frequency hopping, or is transmitted with frequency hopping, and two hops are within the second frequency range. The first value range may also be that L is 4 or less.

Specifically, when the value of L is within the range of the first value and S is within the range of the third value, the PUCCH is transmitted without frequency hopping, or the PUCCH is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the transmission by frequency hopping. For example, condition (4) may be used together with condition (6).

For example, the fourth information and the fifth information may be, respectively, the MIB, SIB 1, DCI for scheduling the PDSCH carrying SIB 1, RRC signaling, or DCI.

[0083] In a possible implementation manner, whether the uplink control channel is transmitted without frequency hopping, or the uplink control channel is transmitted with frequency hopping, and the frequency range that does not require frequency tuning between two adjacent hops of the transmission by frequency hopping may be called the range of the first type of value.

This is not limited in this application. In the embodiments of this application, communication between a terminal device and a network device is used as an example for illustration.

[0126] An example of the system architecture in the embodiments of this application will first be described with reference to FIG. 1. As shown in FIG. 1, the system architecture includes terminal devices and a base station (or referred to as an access network). For example, the terminal devices are terminal device #1 and terminal device #2.

[0129] The terminal devices in this application may be classified into a first type of terminal device and a second type of terminal device. The first type of terminal device is, for example, a reduced capability UE (REDCAP UE). The second type of terminal device may be a legacy UE, for example, an eMBB UE.

[0130] The first type of terminal device and the second type of terminal device have different characteristics. The characteristics include one or more of the following: namely, bandwidth, number of supported or configured resources, number of transmit antenna ports and / or number of receive antenna ports, number of radio frequency channels, number of hybrid automatic repeat request (HARQ) processes, supported peak rate, applicable scenario, delay requirement, processing capacity, protocol version, duplex mode, and service.

[0131] The above characteristics will be described in detail below by using examples.

[0132] Bandwidth or channel bandwidth or maximum channel bandwidth supported or configured by the terminal device: The first type of terminal device and the second type of terminal device have different bandwidths. For example, the bandwidth of the first type of terminal device may be 20 MHz, 10 MHz, or 5 MHz, and the bandwidth of the second type of terminal device may be 100 MHz. With the development of communication technologies, it can be understood that the maximum channel bandwidth supported by the first type of terminal device may no longer be 20 MHz, 10 MHz, or 5 MHz, but may evolve to a wider or narrower bandwidth, for example, 3 MHz, 25 MHz, or 50 MHz.

[0133] Number of supported or configured resources: The number of resources may be the number of resource blocks (RB), time-frequency resource elements (RE), sub-carriers, RB groups, resource element group bundle units (REG bundle), control channel elements, sub-frames, radio frames, slots, mini-slots and / or symbols. The number of resources supported or configured by a first type of terminal device is different from the number of resources supported or configured by a second type of terminal device. For example, the number of resources supported by a first type of terminal device is 48 RBs, and the number of resources supported by a second type of terminal device is 96 RBs.

[0134] Number of transmit antenna ports and / or receive antenna ports: The number of transmit antenna ports and / or receive antenna ports of a first type of terminal device is different from that of a second type of terminal device. For example, the number of transmit antenna ports of a first type of terminal device may be 1, and the number of receive antenna ports of a first type of terminal device may be 2. The number of transmit antenna ports of a second type of terminal device may be 2, and the number of receive antenna ports of a second type of terminal device may be 4.

[0135] Number of radio frequency channels: The number of radio channels of a first type of terminal device is different from that of a second type of terminal device. For example, the number of radio frequency channels of a first type of terminal device may be 1, and the number of radio frequency channels of a second type of terminal device may be 2.

[0136] Number of HARQ processes: The number of HARQ processes supported by a first type of terminal device is different from that supported by a second type of terminal device. For example, the number of HARQ processes of a first type of terminal device may be 8, and the number of HARQ processes of a second type of terminal device may be 16.

[0137] Supported peak rate: The maximum peak rate of the first type of terminal device is different from that of the second type of terminal device. For example, the maximum peak rate supported by the first type of terminal device may be 100 Mbps, and the peak rate supported by the second type of terminal device may be 200 Mbps.

[0138] Applicable scenarios: The first type of terminal device and the second type of terminal device serve different applicable scenarios. For example, the first type of terminal device is applicable to industrial wireless sensing, video surveillance, wearable devices, etc., and the second type of terminal device is applicable to mobile communication, video, Internet access, etc.

[0139] Delay requirements: The first type of terminal device and the second type of terminal device have different transmission delay requirements. For example, the delay requirement of the first type of terminal device may be 500 milliseconds, and the delay requirement of the second type of terminal device may be 100 milliseconds.

[0140] Processing capacity: Under the conditions of different subcarrier spacings (SCS), the first type of terminal device and the second type of terminal device have different processing speeds for channel or data processing time series. For example, the first type of terminal device does not support complex calculations. Complex calculations may include artificial intelligence (AI) and virtual reality (VR) rendering. The second type of terminal device supports complex calculations. Alternatively, it is understood that the processing capacity of the first type of terminal device is lower than that of the second type of terminal device.

[0141] Protocol Version: The first type of terminal device and the second type of terminal device are terminal devices with different protocol versions. For example, the protocol versions supported by the first type of terminal device are Release 17 and protocol versions later than Release 17, and the protocol versions supported by the second type of terminal device are protocol versions earlier than Release 17, for example, Release 15 or Release 16.

[0142] Duplex Mode: The duplex mode includes half-duplex mode and full-duplex mode. The first type of terminal device and the second type of terminal device use different duplex modes. For example, the first type of terminal device operates in half-duplex mode, and the second type of terminal device operates in full-duplex mode.

[0143] Services: Services include, but are not limited to, Internet of Things applications such as video surveillance and mobile broadband (MBB). The first type of terminal device and the second type of terminal device support different services. For example, the service supported by the first type of terminal device is video surveillance, and the service supported by the second type of terminal device is mobile broadband MBB. This is not limited in this embodiment of this application.

[0144] It should be understood that other types of terminal devices or future new types of terminal devices that also support the technical solutions of this application are within the protection scope of this application.

[0145] The first terminal device or terminal device #1 in this application may be an example of the first type of terminal device, and the second terminal device or terminal device #2 may be an example of the second type of terminal device.

[0146] The first frequency range in this application is larger than the maximum channel bandwidth supported by the first type of terminal device, the second frequency range in this application is less than or equal to the maximum channel bandwidth supported by the first type of terminal device, and it should be further noted that the third frequency range in this application is less than or equal to the maximum channel bandwidth supported by the second type of terminal device. The first frequency range and the second frequency range correspond to the first type of terminal device, and the third frequency range corresponds to the second type of terminal device. The first frequency region resource corresponds to the resource that is within the first frequency range and is used by the first type of terminal device to transmit uplink control information. The second frequency region resource corresponds to the resource that is within the second frequency range and is used by the first type of terminal device to transmit uplink control information. The third frequency region resource corresponds to the resource that is within the third frequency range and is used by the second type of terminal device to transmit uplink control information.

[0147] Network device

[0148] The network device in the embodiments of this application is configured to communicate with the terminal device, and may be a radio base station in the network, or may be a network element of a radio access network (RAN), and is responsible for all functions related to the air interface. The functions of the base station include a radio link maintenance function including maintaining a radio link with the terminal and protocol conversion between radio link data and Internet protocol (IP) data, a radio resource management function including radio link establishment and release, radio resource scheduling and allocation, etc., and several mobility management functions including terminal configuration for measurement, terminal radio link quality evaluation, determination of inter-cell handover of the terminal, etc.

[0149] The network device may be an evolved NodeB (eNB or eNodeB) in an LTE system, a base station (gNodeB, gNB) in a 5G network, or a radio controller in a cloud radio Access Network (CRAN) scenario. Alternatively, the network device may be a relay station, an access point, an in-vehicle device, a satellite, a wearable device, a transmitting and receiving point (TRP), a transmitting point (TP), a mobile switching center, or a device that provides base station functionality in Device-to-Device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, and Internet of Things (IoT) communication, or a base station in a future evolved network such as 6G. This is not limited in this embodiment of this application.

[0150] With the continuous development of mobile communication technologies, various terminal devices with different capabilities have emerged. The International Telecommunication Union (ITU) has defined three main application scenarios for 5G mobile communication systems and future mobile communication systems, namely, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (URLLC), and massive machine type communication (mMTC). Typical eMBB services include ultra-high-definition video, augmented reality (AR), and virtual reality (VR). Typical URLLC services include wireless control in industrial manufacturing or production procedures, movement control of unmanned vehicles and unmanned aircraft, and tactile interaction applications such as remote repair and remote surgery. Typical mMTC services include wearables, sensors, video surveillance, smart grid distribution automation, smart cities, etc. These services are mainly characterized by a huge number of connected mMTC terminal devices, a small amount of data transmission, and low data transmission latency requirements. Generally, these mMTC terminal devices need to meet the requirements for low cost and long standby time.

[0151] Furthermore, currently, the 3rd Generation Partnership Project (3GPP) is considering reduced-capability terminal devices. The technology for achieving reduced capability is to reduce the terminal capability by reducing the maximum channel bandwidth supported by the terminal device.

[0152] Based on the above description, terminal devices in different application scenarios may have different capabilities, and it can be easily understood that terminal devices with different capabilities have different requirements for the mobile communication system. Specifically, the maximum channel bandwidth supported by terminal devices with different capabilities may be different. For example, for the frequency range FR1 of the NR system (i.e., the frequency range of 410 MHz to 7125 MHz), the maximum channel bandwidth supported by a normal eMBB terminal device is 100 MHz. For a terminal device with reduced capabilities, in order to reduce the complexity and cost of the terminal device, the maximum channel bandwidth supported by the terminal device may be 5 MHz or 10 MHz or 20 MHz or 40 MHz.

[0153] The above terminal devices with different capabilities may coexist in the same communication system. However, since the maximum channel bandwidths supported by terminal devices with different capabilities are different, the problem of resource fragmentation may be caused. The following can be understood. In a terminal device with a small maximum channel bandwidth, it may cause the frequency domain resources of a terminal device with a large maximum channel bandwidth to be divided into several small frequency domain resources. When the network device allocates resources to the terminal devices providing services, the resources can only be allocated to the terminal devices on several scattered frequency domain resources. There are significant restrictions on the scheduling of the network device, and as a result, the flexibility of resource allocation is reduced.

[0154] Therefore, how to better support the coexistence of terminal devices with different capabilities in the same communication system and avoid the restrictions on resource scheduling caused by resource fragmentation has become an urgent issue to be solved.

[0155] The following further describes the technical problem in this application by way of example using the following, namely, a physical uplink control channel (PUCCH) resource used to transmit a hybrid automatic repeat request (HARQ) for a contention resolution message (i.e., the following Msg4) in a random access process by a terminal device to a network device.

[0156] Random access is a process necessary to establish a radio link between a terminal device and a network device. Normally, data interoperability (normal DL / UL transmission) can be performed between the network device and the terminal device only after random access is completed. The terminal device may realize two basic functions through random access. (1) Uplink synchronization is established to realize uplink synchronization with the network device. (2) A unique terminal identifier, i.e., a cell-radio network temporary identifier (C-RNTI), is established to request the network device to allocate uplink resources.

[0157] The random access process includes a contention-based random access process and a contention-free random access process. In the contention-based random access process, the UE randomly selects a random access preamble and starts a random access process to the network device. Therefore, if multiple UEs use the same preamble to start a random access process simultaneously, a contention may occur and the access may fail. In the contention-free random access process, during access, the UE uses a specific access preamble provided by the network device, thus avoiding contention with other UEs and ensuring the access success rate.

[0158] First, regarding the random access process 100 of the terminal device, with reference to FIG. 2, the contention mode-based four-step random access process will be used as an example and described below.

[0159] S101: The terminal device starts a random access request to the network device on a preconfigured random access channel opportunity (RACH occasion, RO) resource. The random access request may include a first random access preamble or may be Message 1 in the random access process, i.e., Msg1.

[0160] It should be noted that before S101, the random access process further includes the following. The terminal device receives a broadcast message from the network device and randomly selects a random access preamble from some random access preambles in the broadcast message as the first random access preamble.

[0161] It should be understood that multiple terminal devices may send random access requests on the same RO resource, and these terminal devices may be distinguished based on different preambles. However, since the number of preambles in the above broadcast message is limited, multiple UEs may select the same preamble. This problem may be solved in step S104.

[0162] S102: The network device sends a random access response (random access response, RAR) (which may also be called Message 2, i.e., Msg2) to the terminal device.

[0163] Note that the random access response contains uplink grant (UL grant) information. The uplink grant information indicates the resources for the terminal device to transmit Msg3.

[0164] S103: The terminal device transmits message 3 (which may also be referred to as Msg3) to the network device based on the resources indicated by the uplink scheduling information.

[0165] S104: The network device transmits a contention resolution message (a new message 4, which may also be referred to as Msg4) to the terminal device.

[0166] Since the preambles selected by different terminal devices may conflict with each other, multiple terminal devices may select the same preamble. In this step, the network device indicates the terminal devices that have successfully accessed the network.

[0167] After S104, the terminal device performs HARQ feedback on Msg4 received on the PUCCH resource.

[0168] With reference to FIG. 3 and Table 1, the PUCCH resources used by the terminal device to feedback Msg4 will be further described below.

[0169] Note that terminal devices in the NR system usually transmit information in a bandwidth part (BWP) (see FIG. 3). When the terminal device needs to transmit information in a frequency hopping manner within a slot, the PUCCH resources used for the terminal device's frequency hopping are usually located at both ends of the BWP. The resources corresponding to the PUCCH resources used for frequency hopping are continuous in the time domain and discontinuous in the frequency domain.

[0170] It should be understood that frequency hopping may be performed on the PUCCH resources used by the terminal device to feedback Msg4. The optional time-frequency resource positions of the first hop and the second hop may be predefined.

[0171] Table 1 below shows the possible optional resource positions of the first hop and the second hop of the PUCCH resources. The index in the first column indicates the PUCCH resource set. The number of symbols in the fourth column indicates the number of symbols occupied by the PUCCH resource set in the time domain, which may be denoted as L. The physical resource block offset in the fifth column indicates the physical resource block offset parameter corresponding to the PUCCH resource set in the frequency domain, denoted as RB BWP offset and may be denoted as such. The initial cyclic shift in the sixth column indicates the initial cyclic shift index set corresponding to the PUCCH resource set in the frequency domain. The total number of initial cyclic shift indexes included in the initial cyclic shift index set may be denoted as N CS and may be denoted as such. N BWP size is the number of resource blocks RB included in the BWP.

Table 1

[0172] Figure 3 shows the time-frequency distribution of the PUCCH resources within the PUCCH resource set with an index of 0 in Table 1 (Figure 3 shows only 8 PUCCH resources, each PUCCH resource includes the RB corresponding to the first hop and the RB corresponding to the second hop, and the RBs corresponding to the two hops are located at both ends of the BWP).

[0173] The meaning of the parameters in Table 1 is further described with reference to FIG. 3 by using the first row in Table 1 (i.e., the PUCCH resource set indicated by index 0).

[0174] The first row in Table 1 corresponds to the PUCCH resource set with an index of 0. The PUCCH resource set contains 16 PUCCH resources. PUCCH format 0 means that the PUCCH format corresponding to the PUCCH resource set is PUCCH format 0. In the time domain, start symbol 12 means that the start symbol corresponding to the PUCCH resource set is the 12th symbol. The PUCCH resource set occupies two symbols, which means that the PUCCH resource set occupies the 12th and 13th symbols (see FIG. 3). In the frequency domain, PRB offset 0 means that the offset of the resource block where the first PUCCH resource in the PUCCH resource set is located with respect to the RB at the boundary of the BWP (i.e., the resource block with an index of 0 in FIG. 3) is 0. The initial cyclic shift {0, 3} indicates that the total number of initial cyclic shift indices included in the initial cyclic shift index set is 2. Specifically, this means that the initial cyclic shift 0 and the initial cyclic shift 3 can be used by two PUCCH resources respectively to ensure orthogonality. To prevent interference, different cyclic shifts are used by the two PUCCH resources. One PUCCH resource uses cyclic shift 0, and the other PUCCH resource uses cyclic shift 3. 16 PUCCH resources are allocated to both ends of the BWP, and 8 PUCCH resources are allocated to each end.

[0175] It should be noted that the PUCCH resources of the terminal device may be indicated by the network device. For example, the network device may first use a system information block (SIB) (e.g., SIB 1) to indicate the index of the PUCCH resource set, for example, indicate the PUCCH resource set with an index of 0 in Table 1, and then may further indicate the PUCCH resources within the PUCCH resource set. The index of the PUCCH resources within the PUCCH resource set may be represented as r PUCCH For example, the PUCCH resource with r PUCCH =0 may be indicated in the PUCCH resource set with an index of 0 (including 16 resources).

[0176] In FIG. 3, the index of the RB of the resource corresponding to the first hop and used by the terminal device to feedback Msg4, and the index of the RB of the resource corresponding to the second hop and used by the terminal device to feedback Msg4 may be calculated as follows.

[0177] When the PUCCH resource index r PUCCH is 0 to 7, that is, floor(r PUCCH / 8)=0, the index of the RB corresponding to the first hop of the PUCCH within the BWP range (which may be denoted as X1) is

Number

[0178] In this case, the index of the RB corresponding to the second hop of the PUCCH (which may be denoted as X2) is

Number

[0179] The PUCCH resource index is 8 to 15, that is, floor(r PUCCH / 8)=1. In this case, the index of the RB corresponding to the first hop of the PUCCH (which may be denoted as X1) is

Number

[0180] In this case, the index of the RB corresponding to the second hop of the PUCCH (which may be denoted as X2) is

Number

[0181] N BWP size is the number of resource blocks RB included in the BWP in which the terminal device operates. RB BWP offset is the physical resource block offset parameter corresponding to the PUCCH resource set in the frequency domain. r PUCCH is the index value of the PUCCH resource within the PUCCH resource set. N CS is the total number of initial cyclic shift indexes included in the initial cyclic shift index set. floor(r PUCCH / 8) indicates the floor of the result of r PUCCH / 8,

Number

[0182] For example, in FIG. 3 (the index of the corresponding PUCCH resource set is 0), the index of the RB where the first hop of the PUCCH resource with r PUCCH 0 is located is 0 + [0 / 2] = 0, and the index of the RB where the second hop of the PUCCH resource with r PUCCH 0 is located is N BWPsize -1 - 0 - [0 / 2] = N BWP size It is - 1.

[0183] From the perspective of network devices, the resources used by a terminal device (hereinafter may be referred to as terminal device #1) to transmit the first hop and the second hop of PUCCH by frequency hopping cause the frequency resources to be divided, resulting in the problem of resource fragmentation.

[0184] Figure 4 shows the resource positions of two terminals with different capabilities. Terminal device #1 may be a reduced capability user equipment (RedCap UE). Terminal device #2 may be an eMBB terminal device. The maximum channel bandwidth supported by the eMBB terminal device is larger than the maximum channel bandwidth supported by the RedCap UE. When the first hop and the second hop of the PUCCH resources used for HARQ feedback of Msg4 by the RedCap UE are within the BWP range of the eMBB terminal device, the frequency domain resources available for the eMBB terminal device are divided into the resources of three segments indicated by the arrows in Figure 4, and there is a problem of resource fragmentation. When the network device allocates resources to the eMBB terminal device, the resources can only be allocated to the eMBB terminal device on three scattered frequency domain resources (i.e., frequency domain resource #1, frequency domain resource #2, and frequency domain resource #3). There are significant restrictions on the scheduling of the network device, resulting in a reduction in the flexibility of resource allocation.

[0185] In the initial access process of the RedCap UE, it should be understood that the uplink transmission of the RedCap UE needs to be transmitted within the bandwidth of the initial UL BWP configured for the RedCap UE (or within the range of the maximum channel bandwidth supported by the RedCap UE). The first hop and the second hop of the PUCCH resources used for the HARQ feedback of Msg4 by the corresponding RedCap UE also need to be transmitted on the initial UL BWP.

[0186] This embodiment of this application is described by using a reduced-capability terminal device and an eMBB terminal device as examples. It should be further understood that this embodiment of this application is further described by using, for example, the PUCCH resources in frequency hopping used for the HARQ feedback of Msg4 transmitted by the network device in the random access process of the terminal device. This should not constitute a limitation to this application. In fact, regardless of whether frequency hopping is required or not, or regardless of the specific type of terminal device, as long as the channel bandwidths supported by two terminal devices with different capabilities have a part or all of the same frequency range, the terminal device supporting the small maximum channel bandwidth may cause frequency domain resource fragmentation of the terminal device supporting the large maximum channel bandwidth. The technical problem in this scenario can be solved by using the technical solution in this application.

[0187] To solve the above problems, this application provides a communication method for re-determining the PUCCH resources used by terminal device #1 and avoiding resource fragmentation of terminal device #2. The re-determined PUCCH resources used by terminal device #1 are within a first frequency range, and the first frequency range is larger than the BWP in which terminal device #1 operates (or larger than the maximum channel bandwidth supported by terminal device #1). For example, the re-determined PUCCH resources used by terminal device #1 may be located at both ends of the carrier, or may be adjacent to the PUCCH resources of terminal device #2 (which may be understood as being adjacent in frequency to the resources used by terminal device #2 to transmit uplink control information. For example, the resource block where the PUCCH resources of terminal device #1 are located and the resource block where the PUCCH resources of terminal device #2 are located are resource blocks adjacent in frequency).

[0188] Next, the information transmission method 200 in this application will be described in detail with reference to FIG. 5. It should be noted that the terminal device in the following method 200 is the above-mentioned terminal device #1.

[0189] S201: The terminal device determines the number of initial cyclic shift indexes included in the target offset parameter, uplink control channel resource index, physical resource block offset parameter, and initial cyclic shift index set.

[0190] In a possible implementation, the terminal device may determine one of the following parameters, namely, the target offset parameter, uplink control channel resource index, physical resource block offset parameter, and the number of initial cyclic shift indexes included in the initial cyclic shift index set, based on the first configuration information. The first configuration information may be transmitted by the network device to the terminal device.

[0191] By way of example and not limitation, the method for determining the target offset parameter includes, but is not limited to, the following several methods. (1) The terminal device determines the target offset parameter based on a first position and a second position. The first position is the position of the y-th resource block index within a first frequency range, and the second position is the position of the resource block where the resource block index is z within a second frequency range. y and z are non-negative integers. The first frequency range is larger than the maximum channel bandwidth supported by the terminal device, and the second frequency range is less than or equal to the maximum channel bandwidth supported by the terminal device. Optionally, y and z may be the same. For example, y = z = 0 may be possible. (2) The terminal device determines the target offset parameter based on first information, and the first information is received by the terminal device from the network device. For example, the first information is a master information block (MIB), a system information block 1 (SIB 1), a field within SIB 1, downlink control information for scheduling the PDSCH carrying SIB 1, or a field within the DCI for scheduling the PDSCH carrying SIB 1. (3) The target offset parameter is a predefined parameter. For example, the terminal device determines the target offset parameter in a predefined manner. The target offset parameter may be a predefined value. (4) The terminal device (which may also be referred to as terminal device #1) determines the target offset parameter according to a predefined rule. For example, based on the frequency position occupied by a PUCCH resource set configured by another terminal device having resource contention (which may also be referred to as terminal device #2) (an example of a predefined rule), the terminal device determines the target offset parameter, so that the frequency domain resource of the PUCCH of terminal device #1 is at a frequency position adjacent to the frequency domain resource of the PUCCH of terminal device #2.For example, the resource block where the PUCCH resource of terminal device #1 is located and the resource block where the PUCCH resource of terminal device #2 is located are adjacent resource blocks in terms of frequency.

[0192] Optionally, the value of the target offset parameter may be an integer less than 0, or may be an integer multiple of K, where K = 2, 3, or 4.

[0194] When the uplink control channel transmission is transmission by frequency hopping, it should be noted that the target offset parameter may be used to separately determine the first resource block index corresponding to the p-th hop of the transmission by frequency hopping and the second resource block index corresponding to the q-th hop, where p and q are positive integers. Alternatively, the target offset parameter may be used to separately determine the frequency positions corresponding to the p-th hop and the q-th hop of the transmission by frequency hopping.

[0195] Optionally, p = 1 and q = 2, or p = 2 and q = 1.

[0196] When the uplink control channel transmission is transmission by frequency hopping, it should be noted that the target offset parameter may include a first sub-offset parameter and a second sub-offset parameter. The first sub-offset parameter is used to determine the first resource block index. The second sub-offset parameter is used to determine the second resource block index.

[0197] In a possible implementation manner, floor(r PUCCH / 8)=0 is used as an example, and floor(r PUCCH / 8) represents the floor of the result of r PUCCH / 8. The terminal device determines the first resource block index (denoted as X1) based on the following correspondence relationship among the target offset parameter, the uplink control channel resource index, the physical resource block offset parameter, and the number of initial cyclic shift indexes included in the initial cyclic shift index set.

[0203] Optionally, before the terminal device determines the target offset parameter, the terminal device may first determine that the subcarrier spacing (which may be denoted as S) corresponding to the first terminal device and the number of symbols of the uplink control channel resources (which may be denoted as L) satisfy a first preset condition.

[0204] By way of example and not limitation, the first preset condition may be one or more of the following conditions.

[0205] (1) The minimum value of L is 4 or more.

[0206] (2) The minimum value of L is determined based on S.

[0207] (3) The value of L is within the range of the first value, and the uplink control channel is transmitted without frequency hopping within the range of the first value, or the uplink control channel is transmitted with frequency hopping within the range of the first value, and no frequency tuning is required between two adjacent hops of the transmission by frequency hopping.

[0208] By way of example and not limitation, the range of the first value may include {2, 4, 10}.

[0209] (4) The value of L is within the range of the second value, and the uplink control channel is transmitted with frequency hopping within the range of the second value, and frequency tuning is required between two adjacent hops of the transmission by frequency hopping.

[0210] By way of example and not limitation, the range of the second value may include {14}.

[0211] (5) The value of S is within the range of the third value, and the uplink control channel is transmitted without frequency hopping within the range of the third value, or the uplink control channel is transmitted with frequency hopping within the range of the third value, and no frequency tuning is required between two adjacent hops of the transmission by frequency hopping.

[0212] By way of example and not limitation, the range of the third value may include 15 kHz, 30 kHz, 60 kHz, or a value greater than 60 kHz.

[0213] (6) The value of S is within the range of the fourth value, and the uplink control channel can be transmitted with frequency hopping within the range of the fourth value, and frequency tuning is required between two adjacent hops of the transmission by frequency hopping.

[0214] By way of example and not limitation, the range of the fourth value may include 15 kHz, 30 kHz, or 60 kHz.

[0215] S203: The terminal device transmits uplink control information on the resource related to the resource block index.

[0216] It should be noted that the terminal device may transmit uplink control information without frequency hopping on the resource related to the resource block index, or may transmit uplink control information with frequency hopping on the resource related to the resource block index, or may repeatedly transmit uplink control information on the resource related to the resource block index.

[0217] Hereinafter, the information transmission method 300 in this application will be further described with reference to FIG. 6.

[0218] The information transmission method may be understood as follows. The resource #a (corresponding to the second frequency region resource) determined based on the uplink control channel resource index, the physical resource block offset parameter, the number of resource blocks included in the second frequency range (the second frequency range is less than or equal to the maximum channel bandwidth supported by the terminal device), and the number of initial cyclic shift indexes included in the initial cyclic shift index set and used to transmit uplink control information is within the second frequency range. In other words, the resource #a is located in the BWP of the terminal device #1, or the resource #a is within the maximum channel bandwidth supported by the terminal device #1. The resource #a causes fragmentation of the available resources (corresponding to the third frequency range) of the terminal device #2. Here, the resource #a may be determined according to Formulas 1 to 4, and the details will not be described again here. Based on this, the terminal device #1 first determines the first frequency range and the first offset parameter (which may be denoted as Z1), and then determines the resource #b used to transmit uplink control information based on the first offset parameter, the number of resource blocks included in the first frequency range (the first frequency range is greater than the maximum channel bandwidth supported by the terminal device), the uplink control channel resource index, the physical resource block offset parameter, and the number of initial cyclic shift indexes included in the initial cyclic shift index set. The resource #b is within the first frequency range and the resource #b is outside the second frequency range. This improves the frequency hopping gain for transmitting PUCCH, reduces the restrictions on resource allocation for the terminal device #2, reduces resource fragmentation, and improves the flexibility of the available resources of the terminal device #2 from the perspective of the network device.

[0219] It should be noted that the first offset parameter in this embodiment may be understood as the above target offset parameter.

[0220] It should be noted that the first offset parameter may be understood as an offset value between the position of the 0th resource block index within the first frequency range (i.e., the starting RB within the first frequency range) corresponding to the first position and the position of the 0th resource block index within the second frequency range (i.e., the starting RB within the second frequency range) corresponding to the second position. Optionally, the first offset parameter may be in units of RB. The first offset parameter may be a positive value or a negative value, and the positive and negative values respectively correspond to different directions of the first offset parameter. For example, a positive value may indicate an offset in the direction in which the RB index increases, that is, the starting RB within the second frequency range is larger than the starting RB within the first frequency range. A negative value may indicate an offset in the direction in which the RB index decreases, that is, the starting RB within the second frequency range is smaller than the starting RB within the first frequency range. 0 may indicate that the position of the starting RB within the first frequency range coincides with the position of the starting RB within the second frequency range.

[0221] Alternatively, it should be noted that the first offset parameter may be understood as an offset value between the position of the 0th resource block index within the second frequency range (i.e., the starting RB within the second frequency range) corresponding to the second position and the position of the 0th resource block index within the first frequency range (i.e., the starting RB within the first frequency range) corresponding to the first position. Optionally, the first offset parameter may be in units of RBs. The first offset parameter may be a positive value or a negative value, and the positive and negative values respectively correspond to different directions of the first offset parameter. For example, a positive value may indicate an offset in the direction in which the RB index increases, i.e., the starting RB within the second frequency range is smaller than the starting RB within the first frequency range. A negative value may indicate an offset in the direction in which the RB index decreases, i.e., the starting RB within the second frequency range is larger than the starting RB within the first frequency range. 0 may indicate that the position of the starting RB within the first frequency range coincides with the position of the starting RB within the second frequency range.

[0222] It should be further noted that the first frequency range may be a carrier, or a BWP in which the terminal device #2 operates, or any bandwidth larger than the second frequency range within the carrier, or any frequency range in which the bandwidth is larger than the second frequency range (any BWP in which the bandwidth is larger than the second frequency range). This is not limited in this application on the condition that it can be ensured that the resource #b is outside the second frequency range.

[0223] In a possible implementation, resource #b is a resource used by terminal device #1 to transmit (or send) uplink control information by frequency hopping. In this case, the resource corresponding to the first hop and transmitting uplink control information may be denoted as resource #b1. The resource corresponding to the second hop and transmitting uplink control information may be denoted as resource #b2. Resource #b1 and resource #b2 are within the first frequency range. For example, resource #b1 and resource #b2 are located at both ends of the carrier respectively. Alternatively, resource #b1 and resource #b2 are separately adjacent to the PUCCH resource of terminal device #2. Similarly, for the sake of easy explanation, resource #a in a scenario with frequency hopping is also classified into resource #a1 and resource #a2.

[0224] It should be noted that in order to solve the problem of resource fragmentation in the information transmission method, the network device may instruct terminal device #1 to determine the above related parameters of resource #b (or resource #b1 and resource #b2). The methods for determining the first offset parameter include, but are not limited to, the following several methods.

[0225] (1) The network device directly configures the first offset parameter Z1 for terminal device #1. (2) The network device configures the first frequency range for terminal device #1, and terminal device #1 calculates the first offset parameter Z1 based on the start RB within the first frequency range (corresponding to the first position) and the start RB within the second frequency range (corresponding to the second position).

[0226] Optionally, the network device may carry, in the downlink control information for scheduling SIB 1 or the PDSCH carrying SIB 1, the configuration information related to the first offset parameter or the first frequency range in the above method.

[0227] In a possible implementation manner, a scenario of frequency hopping is used as an example. The terminal device #1 may determine the resource #b1 and the resource #b2 as follows. The terminal device #1 may first determine the positions of the resource #a1 and the resource #a2 within the second frequency range. In this case, refer to Equations 1 to 4. Details will not be described again here. Then, the terminal device #1 determines an offset parameter D1 (corresponding to the first sub-offset) between the resource #a1 and the resource #b1 and an offset parameter D2 (corresponding to the second sub-offset) between the resource #a2 and the resource #b2 based on the first offset parameter. For example, D1 may be the first offset parameter, and D2 may be determined based on the first offset parameter and the number of RBs included in the first frequency range.

[0228] FIG. 6 shows three scenarios (a), (b), and (c) in which the terminal device #1 determines the resource #b1 and the resource #b2 in this application. Each scenario corresponds to a different frequency position relationship between the second frequency range (e.g., BWP) and the first frequency range of the terminal device #1 (e.g., RedCap UE). In all the above three scenarios, the frequency resource positions corresponding to the resource #b1 and the resource #b2 may be determined as follows.

[0229] PUCCH resource index r PUCCH When it is 0 to 7, that is, when floor(r PUCCH / 8)=0, the index X1 of the RB corresponding to the resource #b1 within the first frequency range (i.e., the first resource block index) is

Number

[0230] In this case, the index (i.e., the second resource block index) X2 of the RB corresponding to the resource #b2 within the first frequency range is

Number

[0231] PUCCH resource index r PUCCH is 8 to 15, that is, when floor(r PUCCH / 8) = 1, the index X1 of the RB corresponding to the resource #b1 within the first frequency range (i.e., the first resource block index) is

Number

[0232] In this case, the index (i.e., the second resource block index) X2 of the RB corresponding to the resource #b2 within the first frequency range is

Number

[0233] N size is the number of resource blocks included in the first frequency range, N BWP size is the number of resource blocks included in the second frequency range, RB BWP offset is the physical resource block offset parameter, r PUCCH is the uplink control channel resource index, N CS is the number of initial cyclic shift indices included in the initial cyclic shift index set, D1 is the first sub-offset parameter used to determine the first resource block index, D2 is the second sub-offset parameter used to determine the second resource block index, Z1 is the first offset parameter, floor(r PUCCH / 8) indicates the floor of the result of r PUCCH / 8,

Number

[0234] Note that the frequency positions of resource #b1 and resource #b2 are related to the total number of RBs within the first frequency range and the first offset parameter.

[0235] In a possible implementation, before the terminal device #1 determines resource #b (or resource #b1 and resource #b2), the information transmission method may further include the following. The network device determines that the resource #a (or resource #a1 and resource #a2) corresponding to the terminal device #1 does not meet a preset condition #1. The preset condition #1 is used to determine whether the resource #a (or resource #a1 and resource #a2) corresponding to the terminal device #1 causes fragmentation of the available resources of other terminal devices (e.g., terminal device #1). For example, the preset condition #1 may be that the resource #a (or resource #a1 and resource #a2) corresponding to the terminal device #1 is located in the BWP of the terminal device #2. If the preset condition #1 is not met, it may be understood that the BWPs of the terminal device #1 and the terminal device #2 do not overlap in frequency. In other words, there is no problem of resource fragmentation.

[0236] In the above information transmission method, the terminal device #1 may determine that the resource #b (or resource #b1 and resource #b2) outside the second frequency range is used to transmit uplink control information based on the first offset parameter and the first frequency range. The resource #b (or resource #b1 and resource #b2) is within the first frequency range. The resource #b (or resource #b1 and resource #b2) may be located at both ends of the carrier or adjacent to the resource used by the terminal device #2 to transmit uplink control information. This avoids the problem of resource fragmentation.

[0237] The information transmission method 400 in this application will be further described below with reference to FIG. 7.

[0238] The information transmission method may be further understood as follows. The terminal device #1 does not necessarily need to determine resource #a (or resource #a1 and resource #a2), nor does it need to determine offset parameter D1 and offset parameter D2. It only needs to determine resource #b based on the first frequency range, the uplink control channel resource index, the physical resource block offset parameter, and the number of initial cyclic shift indexes included in the initial cyclic shift index set. Resource #b is within the first frequency range and outside the second frequency range. This improves the frequency hopping gain for transmitting PUCCH, reduces the restrictions on resource allocation for the terminal device #2, reduces resource fragmentation, and improves the flexibility of the available resources of the terminal device #2 from the perspective of the network device.

[0239] In a possible implementation, the terminal device #1 determines the frequency resource positions corresponding to resource #b1 and resource #b2 as follows.

[0240] PUCCH resource index r PUCCH When it is 0 to 7, that is, when floor(r PUCCH / 8)=0, the index X1 of the RB corresponding to resource #b1 within the first frequency range is

Number

[0241] In this case, the index X2 of the RB corresponding to resource #b2 within the first frequency range is

Number

[0242] PUCCH resource index rPUCCH When it is 8 to 15, that is, when floor(r PUCCH / 8) = 1, the index X1 of the RB corresponding to the resource #b1 within the first frequency range is

Number

[0243] In this case, the index X2 of the RB where the second hop of the PUCCH is located is

Number

[0244] N size is the number of resource blocks included in the first frequency range, RB BWP offset is the physical resource block offset parameter, r PUCCH is the uplink control channel resource index, N CS is the number of initial cyclic shift indexes included in the initial cyclic shift index set, floor(r PUCCH / 8) indicates the floor of the result of r PUCCH / 8,

Number

[0245] It should be understood that within different frequency region ranges, the same RB index may indicate different frequency region resources. For example, a resource with an RB index of 0 within the first frequency range and a resource with an RB index of 0 within the second frequency range correspond to different frequency region ranges.

[0246] The resource #b (or resource #b1 and resource #b2) determined in the above embodiment of this application can avoid the problem of resource fragmentation from the perspective of network devices. However, the resource #b (or resource #b1 and resource #b2) may conflict with the resource (i.e., the third frequency domain resource) determined by the terminal device #2 and used to transmit uplink control information. To further avoid the conflict between the frequency domain resources of the PUCCH of the terminal device #1 and the terminal device #2 and further improve the flexibility of the frequency positions of the first hop and the second hop corresponding to the frequency domain resource of the PUCCH of the terminal device #1, the network device may further configure an offset parameter (which may be denoted as the second offset parameter N_offset) of the resource #b (or resource #b1 and resource #b2) for the terminal device #1. The terminal device #1 may further adjust the frequency position of the PUCCH based on the second offset parameter to avoid resource conflict. For example, the PUCCH resource of the terminal device #1 may be allocated to a frequency position adjacent to the PUCCH resource of the terminal device #2 based on the second offset parameter.

[0247] Optionally, the second offset parameter may be in units of RB. The second offset parameter may be a positive value or a negative value, and the positive value and the negative value respectively correspond to different directions of the second offset parameter. For example, the positive value may indicate an offset in the direction in which the RB index increases, that is, the starting RB within the second frequency range is larger than the starting RB within the first frequency range. The negative value may indicate an offset in the direction in which the RB index decreases, that is, the starting RB within the second frequency range is smaller than the starting RB within the first frequency range. 0 may indicate that the position of the starting RB within the first frequency range coincides with the position of the starting RB within the second frequency range. For example, the positive value may indicate an offset in the direction in which the RB index increases, that is, the starting RB within the second frequency range is smaller than the starting RB within the first frequency range. The negative value may indicate an offset in the direction in which the RB index decreases, that is, the starting RB within the second frequency range is larger than the starting RB within the first frequency range. 0 may indicate that the position of the starting RB within the first frequency range coincides with the position of the starting RB within the second frequency range.

[0248] In this embodiment, the second offset parameter may be understood as a target offset parameter indicating that the first sub-offset parameter is the same as the second sub-offset parameter.

[0249] As shown in FIG. 7, a scenario with frequency hopping is used as an example. The positions of resource #b1 and resource #b2 may be adjusted based on the second offset parameter (N_offset), and the resources #b1 and #b2 obtained after the position adjustment are denoted as resource #b11 and resource #b22 respectively.

[0250] In a possible implementation manner, the terminal device #1 determines the frequency resource positions corresponding to the resources #b11 and #b22 as follows.

[0251] PUCCH resource index rPUCCH When it is 0 to 7, that is, when floor(r PUCCH / 8) = 0, the index X1 of the RB corresponding to resource #b11 is

[0252] In this case, the index X2 of the RB corresponding to resource #b22 is

Number

[0253] PUCCH resource index r PUCCH When it is 8 to 15, that is, when floor(r PUCCH / 8) = 1, the index X1 of the RB corresponding to resource #b11 is

[0254] In this case, the index X2 of the RB corresponding to resource #b22 is

Number

[0255] In this implementation method, the target offset parameter may be understood to include the second offset parameter.

[0256] Referring to the embodiment corresponding to FIG. 6, the frequency resource positions corresponding to resource #b11 and resource #b22 are determined in other possible ways.

[0257] PUCCH resource index r PUCCH When it is 0 to 7, that is, when floor(r PUCCHWhen (r / 8) = 0, the index X1 of the RB corresponding to resource #b11 (i.e., the first resource block index) is

[0259] PUCCH resource index r PUCCH is 8 to 15, that is, when floor(r PUCCH / 8) = 1, the index X1 of the RB corresponding to resource #b11 (i.e., the first resource block index) is

Number

[0260] In this case, the index X2 of the RB corresponding to resource #22 (i.e., the second resource block index) is

Number

[0261] N_offset is the second offset parameter, N size is the number of resource blocks included in the first frequency range, N BWP size is the number of resource blocks included in the second frequency range, RB BWP offset is the physical resource block offset parameter, r PUCCH is the uplink control channel resource index, N CSis the number of initial cyclic shift indexes included in the initial cyclic shift index set, Z1 is the first offset parameter, floor(r PUCCH / 8) indicates the floor of the result of r PUCCH / 8,

Number

[0262] In this implementation method, the target offset parameter may be understood to include the first offset parameter and the second offset parameter.

[0263] It should be noted that the method by which the terminal device #1 determines the second offset parameter may include the following methods.

[0264] (1) The terminal device determines the second offset parameter by receiving the third information of the network device. For example, the third information may be SIB 1, or a field in SIB 1, or DCI for scheduling the PDSCH carrying SIB 1, or a field in the DCI for scheduling the PDSCH carrying SIB 1, or a field in the uplink control channel configuration information PUCCH-ConfigCommon.

[0265] (2) The terminal device determines the second offset parameter in a predefined manner. For example, the second offset parameter may be a predefined value, an integer multiple of 2, an integer multiple of 3, or an integer multiple of 4, and the unit may be RB.

[0266] (3) The terminal device determines a second offset parameter according to a predefined rule. For example, the second offset parameter is determined based on the frequency position occupied by the PUCCH resource set and assigned to terminal device #2 (an example of a predefined rule), so that the frequency domain resource of the PUCCH of terminal device #1 becomes a frequency position adjacent to the frequency domain resource of the PUCCH of terminal device #2.

Table 2

[0267] In the above information transmission method, terminal device #1 may determine that resource #b (or resource #b1 and resource #b2) is used for transmitting uplink control information based on the first frequency range. Resource #b (or resource #b1 and resource #b2) is within the first frequency range. Resource #b (or resource #b1 and resource #b2) may avoid fragmenting the available frequency domain resources of terminal device #2. In the above information transmission method, terminal device #1 further determines a second offset parameter, determines resource #b11 and resource #b22 based on the second offset parameter, and may avoid conflicts with the frequency resources of the PUCCH of terminal device #2. For example, conflicts between the frequency resources used by terminal device #1 to transmit Msg4 and the frequency resources used by terminal device #2 to transmit Msg4 can be avoided. Optionally, the second offset parameter may be used to make the frequency resources of the PUCCH of terminal device #1 and the frequency resources of the PUCCH of terminal device #2 adjacent in the frequency domain.

[0268] Hereinafter, the information transmission method 500 in this application will be further described with reference to FIG. 8.

[0269] In the above embodiment of this application, in a scenario with frequency hopping, the network device configures an offset parameter for one-hop frequency domain resource of the PUCCH of terminal device #1, and terminal device #1 determines the frequency domain resource of another hop of the PUCCH of terminal device #1 based on the offset parameter. In other possible implementation manners, alternatively, the network device may configure offset parameters for two-hop frequency domain resources of the PUCCH of terminal device #1 respectively. For example, the offset parameter corresponding to the first hop of the frequency domain resource may be called the third offset parameter (which may be denoted as RB_offset1), and the offset parameter corresponding to the second hop of the frequency domain resource is denoted as the fourth offset parameter (which may be denoted as RB_offset2).

[0270] In this embodiment, the target offset parameter includes the third offset parameter (corresponding to the first sub-offset parameter) and the fourth offset parameter (corresponding to the second sub-offset parameter).

[0271] As shown in FIG. 8, in this implementation manner, terminal device #1 determines the positions of resource #b1 and resource #b2 based on the third offset parameter and the fourth offset parameter configured by the network device. Specifically, the frequency position of resource #b1 corresponding to the first hop of the PUCCH of terminal device #1 is determined based on the third offset parameter, and the frequency position of resource #b2 corresponding to the second hop of the PUCCH of terminal device #1 is determined based on the fourth offset parameter, avoiding resource fragmentation of terminal device #2. For example, resource #b1 and resource #b2 may be outside the range of the maximum channel bandwidth supported by terminal device #2, or resource #b1 and resource #b2 may be located at both ends of the range of the maximum channel bandwidth supported by terminal device #2.

[0272] In a possible implementation manner, the terminal device #1 determines the frequency resource positions corresponding to the resource #b1 and the resource #b2 as follows.

[0273] PUCCH resource index r PUCCH When it is 0 to 7, that is, when floor(r PUCCH / 8) = 0, the index X1 of the RB corresponding to the resource #b1 within the first frequency range is

[0274] In this case, the index X2 of the RB corresponding to the resource #b2 within the first frequency range is

[0276] In this case, the index X2 of the RB where the second hop of the PUCCH is located is

[0277] N_offset1 is the third offset parameter, N_offset2 is the fourth offset parameter, and N BWP size is the number of resource blocks included in the second frequency range, RB BWP offsetis a physical resource block offset parameter, r PUCCH is an uplink control channel resource index, N CS is the number of initial cyclic shift indexes included in the initial cyclic shift index set, floor(r PUCCH / 8) indicates the floor of the result of r PUCCH / 8,

Number

[0278] It should be noted that the third offset parameter and the fourth offset parameter may be positive or negative values. Positive and negative values respectively correspond to different moving directions in the frequency domain. For example, a positive value may indicate an offset in the direction in which the RB index increases, and a negative value may indicate an offset in the direction in which the RB index decreases. Optionally, the third offset parameter and the fourth offset parameter may be in units of RB.

[0279] It should be further noted that the range of the third offset parameter and the fourth offset parameter is related to the first frequency range. For example, when the first frequency range is a carrier, the units of the third offset parameter and the fourth offset parameter being RB are used as an example. The range of the third offset parameter and the fourth offset parameter is an integer with values from 0 to 274.

[0280] In a possible implementation, the configuration of the third offset parameter and the fourth offset parameter is related to the configuration information PUCCH-ConfigCommon of the uplink control channel. Each PUCCH resource set corresponds to the configuration of a group of the third offset parameter and the fourth offset parameter. Possible structures include at least the following content.

[0281] In a possible implementation manner, the configurations of the third offset parameter and the fourth offset parameter are related to the configuration of the PUCCH resource set. Each resource set corresponds to the configuration of a group of the third offset parameter and the fourth offset parameter. Possible associations are as follows.

[0282] In the above information transmission method, the network device may indicate the third offset parameter and the fourth offset parameter. The network device may flexibly adjust the frequency positions of the first hop and the second hop of the PUCCH of the terminal device #1 (i.e., resource #b1 and resource #b2) based on the third offset parameter and the fourth offset parameter. Correspondingly, in a scenario with frequency hopping, the terminal device #1 may determine the frequency domain positions of resource #b1 and resource #b2 based on the third offset parameter and the fourth offset parameter respectively, and avoid fragmentation of the available frequency domain resources of the terminal device #2.

[0283] To solve the problem of resource fragmentation, in this application, the first hop of the frequency domain resources of the PUCCH resources of terminal device #1 and / or the second hop of the frequency domain resources are outside the maximum channel bandwidth supported by terminal device #1 (i.e., outside the BWP). Therefore, terminal device #1 needs to perform retuning to transmit the first hop of the PUCCH and / or the second hop of the PUCCH. It can be understood that there is a need for an interval of at least the retuning time (for example, the retuning time is 140 microseconds) between the first hop of the frequency domain resources of the PUCCH resources of terminal device #1 and the second hop of the frequency domain resources. As a result, a plurality of symbols of the first hop of the PUCCH resources and / or the second hop of the PUCCH resources may need to be occupied for frequency tuning, and the transmission performance of terminal device #1 deteriorates. In this case, the orthogonality of the PUCCH resources is further impaired, and interference to other terminal devices may be caused.

[0284] The following further describes the information transmission method in this application regarding the above problem of whether frequency tuning is performed between the first hop and the second hop of PUCCH transmission.

[0285] In a possible implementation, terminal device #1 supports frequency hopping outside the BWP in which terminal device #1 operates only when the subcarrier spacing (which may be denoted as S) and the PUCCH length (which may be represented as L) satisfy a preset condition #2. In other words, terminal device #1 performs frequency hopping only within the BWP in which terminal device #1 operates.

[0286] It should be noted that whether the subcarrier spacing S and the PUCCH length L satisfy the preset condition #2 may be determined by the network device, or may be determined by the terminal device (for example, terminal device #1). This is not limited in this application.

[0287] By way of example and not limitation, the preset condition #2 may be that L and / or S satisfy at least one of the following conditions.

[0288] (1) The minimum value of L is 4 or more.

[0289] (2) The minimum value of L is determined based on S.

[0290] (3) The value of L is within a first value range, and the PUCCH is transmitted without frequency hopping, or the PUCCH is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the frequency hopping transmission.

[0291] (4) The value of L is within a second value range, the PUCCH is transmitted with frequency hopping, and frequency tuning is required between two adjacent hops of the frequency hopping transmission.

[0292] (5) The value of S is within a third value range, and the PUCCH is transmitted without frequency hopping, or the PUCCH is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the frequency hopping transmission.

[0293] (6) The value of S is within a fourth value range, the PUCCH can be transmitted with frequency hopping, and frequency tuning is required between two adjacent hops of the frequency hopping transmission.

[0294] When condition (1) is satisfied, two hops of the PUCCH transmission transmitted by the terminal device are outside the second frequency range. For example, when L = 10, two hops of the PUCCH transmission transmitted by the terminal device are outside the second frequency range.

[0295] When condition (2) is satisfied, the two hops of the PUCCH transmission transmitted by the terminal device are outside the second frequency range or within the second frequency range. For example, when S = 15 kHz, the minimum value of L is 10. Specifically, the two hops of the PUCCH transmission transmitted by the terminal device are outside the second frequency range. For example, when S = 30 kHz, the minimum value of L is 14. Specifically, the two hops of the PUCCH transmission transmitted by the terminal device are outside the second frequency range. For example, when S = 60 kHz, the PUCCH transmitted by the terminal device is transmitted without frequency hopping, or the PUCCH is transmitted with frequency hopping, and two adjacent hops of the transmission by frequency hopping are within the second frequency range.

[0296] When condition (3) is satisfied, the PUCCH transmitted by the terminal device is transmitted without frequency hopping, or is transmitted with frequency hopping, and the two hops are within the second frequency range. The first value range may also be that L is 4 or less.

[0297] When condition (4) is satisfied, the two hops of the PUCCH transmission transmitted by the terminal device are outside the second frequency range. The second value range may also be that L is greater than 4 or L is 10 or more.

[0298] When condition (5) is satisfied, the PUCCH transmitted by the terminal device is transmitted without frequency hopping, or is transmitted with frequency hopping, and the two hops are within the second frequency range. The third value range may also be that S is 60 kHz or more, or S is greater than 30 kHz.

[0299] When condition (6) is satisfied, the two hops of the PUCCH transmission transmitted by the terminal device are outside the second frequency range. The fourth value range may also be that S is 30 kHz or less.

[0300] Conditions (1) to (6) may be combined with each other. For example, Condition (3) may be used together with Condition (5). Specifically, when the value of L is within the range of the first value and S is within the range of the third value, PUCCH is transmitted without frequency hopping, or PUCCH is transmitted with frequency hopping and no frequency tuning is required between two adjacent hops of the transmission by frequency hopping. For example, Condition (4) may be used together with Condition (6). Specifically, when the value of L is within the range of the second value and S is within the range of the fourth value, PUCCH can be transmitted with frequency hopping and frequency tuning is required between two adjacent hops of the transmission by frequency hopping.

[0301] In a possible implementation, the network device may send the second information to the terminal device. The second information may indicate whether the uplink control information of the terminal device is transmitted with frequency hopping. Optionally, when the second information indicates that the uplink control information of the terminal device is transmitted with frequency hopping, the second information may further indicate whether frequency tuning needs to be performed for the transmission of the uplink control information by frequency hopping. In other words, the second information may further indicate that the uplink control information is transmitted with frequency hopping within the second frequency range or the uplink control information is transmitted with frequency hopping outside the second frequency range.

[0302] In a possible implementation, terminal device #1 supports frequency hopping outside the initial uplink BWP of terminal device #1 only when the subcarrier spacing (which may be denoted as S) and the PUCCH length (which may be represented as L) satisfy a preset Condition #2 (i.e., the first preset condition). In other words, terminal device #1 does not perform frequency hopping or performs frequency hopping only within the initial uplink BWP of terminal device #1.

[0303] By way of example and not limitation, the preset condition #2 may be that (1) SCS = 15 kHz and the number of PUCCH symbols is 2 or 4, or (2) SCS = 30 kHz or 60 kHz and the number of PUCCH symbols is 2, 4 or 10, or (3) SCS is greater than 60 kHz.

[0304] When the above implementation method is used, the PUCCH resource sets corresponding to some indexes in the existing PUCCH resource set configuration table (for example, Table 1) are not available to the terminal device #1. For example, in Table 1, the PUCCH resource sets corresponding to indexes 0 to 6 cannot be used as PUCCH frequency hopping resources. For the terminal device #1, different time domain configurations may be used for the resources in the PUCCH resource sets corresponding to these indexes.

[0305] Table 3 shows the possible reconfigurations of Table 1. The reconfigurations of the rows in Table 1 where the number of PUCCH symbols is 2 and 4 are as follows. That is, in the first PUCCH resource set, the corresponding indexes in Table 3 are 0, 1, and 2. The PUCCH of terminal device #1 is transmitted within the first time interval, and the first and second hops of the PUCCH may be outside the BWP. Also, in the second PUCCH resource set, the corresponding indexes in Table 3 are 3, 4, 5, and 6. The PUCCH is transmitted within the second time interval, and the first and second hops of the PUCCH may be outside the BWP. The duration of the first time interval is different from the duration of the second time interval. For example, the first time interval may be 1.5 slots or the number of symbols corresponding to 1.5 slots, and the second time interval may be 2 slots or the number of symbols corresponding to 2 slots. The first time interval and the second time interval may not be reflected in the table, that is, they are determined in a predefined manner. For example, L = 10 corresponds to the first time interval, and L = 14 corresponds to the second time interval. The first time interval and the second time interval can ensure that there is sufficient time between the first hop and the second hop for frequency tuning. The network device may indicate whether the terminal device performs frequency hopping based on the fourth information, and / or whether the terminal device performs frequency hopping within or outside the BWP based on the fifth information. For example, the fourth information and the fifth information may be the MIB, SIB 1, DCI for scheduling the PDSCH carrying SIB 1, RRC signaling, or DCI, respectively.

[0306] In an implementation manner, the network device may indicate that the terminal device applies Table 1 or Table 3 based on the Xth information (1 bit or multiple bits). The Xth information may be the MIB, SIB 1, DCI for scheduling the PDSCH carrying SIB 1, RRC signaling, or DCI.

Table 3

[0307] In the above embodiment, only when the subcarrier spacing and the PUCCH length satisfy the preset condition #2, the terminal device #1 performs frequency hopping outside the initial uplink BWP of the terminal device #1. When the subcarrier spacing and the PUCCH length do not satisfy the preset condition #2, the terminal device #1 does not perform frequency hopping outside the initial uplink BWP of the terminal device #1, or alternatively, the terminal device #1 performs frequency hopping only within the initial uplink BWP of the terminal device #1. This reduces the impact of the retuning time on the performance of the short PUCCH corresponding to the terminal device #1.

[0308] It should be noted that in the above embodiment of this application, in a scenario with frequency hopping, both the first hop (corresponding to resource #b1, resource b#11, or the first sub-frequency region resource) and the second hop (corresponding to resource #b2, resource b#22, or the second sub-frequency region resource) may be outside the second frequency range. Alternatively, the first hop may be within the second frequency range and the second hop may be outside the second frequency range. Alternatively, the first hop may be outside the second frequency range and the second hop may be within the second frequency range. The specific positions of the first hop and the second hop are not limited in this application under the condition that the restrictions on the resource scheduling on the network side can be reduced and the flexibility of the resource configuration can be improved.

[0309] It should be further noted that an example where the RB is a unit of the PUCCH resource is used in the description of this embodiment of this application and does not constitute a limitation to this application. In fact, alternatively, RE, subcarrier, etc. may be used as the unit of the PUCCH resource. This is not limited in this application.
