Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular, to a communication method, apparatus, storage medium, and program product. Background Art

[0002] With the development of communication technologies, the interactions between communication devices (such as terminals, base stations, etc.) have become increasingly frequent, and the management requirements for the communication states between communication devices have also become higher. For example, a terminal can send uplink control information (UCI) to a base station through a physical uplink control channel (PUCCH) to feedback channel states, confirm reception states, or request resource scheduling, etc.

[0003] However, during the process of transmitting UCI through PUCCH, the transmission resources in the PUCCH resources between the terminal and the base station for transmitting UCI are determined based on the number of UCI bits carried by the PUCCH. As the channel environment between the terminal and the base station deteriorates (such as deep channel fading, time offset, or frequency offset, etc.), the number of UCI bits carried by the PUCCH will also decrease synchronously, resulting in a reduction in the transmission resources for transmitting UCI, and reducing the demodulation performance of the base station for the PUCCH.

[0004] Therefore, how to manage the transmission resources in the PUCCH resources for transmitting UCI and improve the demodulation performance of the PUCCH has become an urgent technical problem to be solved. Summary of the Invention

[0024] Next, the technical solutions in the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0025] It should be noted that in the present disclosure, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present disclosure should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" aims to present relevant concepts in a specific manner.

[0026] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] In the description of the present disclosure, unless otherwise specified, " / " means "or". For example, A / B may represent A or B. "And / or" herein is merely a relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, "at least one" means one or more, and "a plurality of" means two or more.

[0028] In the related art, the user equipment (UE) side can transmit UCI to the base station side through PUCCH, and the UCI can include a scheduling request (SR), a hybrid automatic repeat request acknowledgment / negative acknowledgment (HARQ-ACK / NACK), channel state information (CSI), and a cyclic redundancy check (CRC), etc.

[0029] For ease of description, some technical terms are as follows:

[0030] The number of PUCCH transmission resources actually transmitted on the UE side finally obtained through the related art or other technologies or methods described in the embodiments of the present disclosure is collectively referred to as the number of PUCCH effective transmission resources.

[0031] The effective transmission resources for transmitting UCI in the PUCCH resources may include physical resource blocks (RBs), subcarriers, and orthogonal frequency division multiplexing (OFDM) symbols. Hereinafter, the effective transmission resources are described by taking the effective resource block RB as an example, and the subcarrier or the OFDM symbol can replace the resource block RB in the description.

[0032] The number of PUCCH RBs (i.e., idle available RBs) configured in the PUCCH resources can be represented by and the number of RBs used for transmitting UCI among the available RBs of the PUCCH resources can be calculated through the following Formula 1 and Formula 2.

[0033] For example, when the bit length of the UCI carried by the PUCCH satisfies Formula 1, the UE side will select the smallest number of RBs that is less than or equal to and satisfies Formula 2 The number of PUCCH RBs for final transmission (i.e., the RBs for transmitting UCI).

[0034]

[0035] where, O ACK represents the bit length of HARQ-ACK in UCI, O SR represents the bit length of SR in UCI, O CSI represents the bit length of CSI in UCI, O CRC represents the bit length of CRC in UCI, and (O ACK + O SR + O CSI + O CRC ) can represent the bit length of UCI, represents the number of subcarriers (sc) actually carrying UCI in each RB of the PUCCH format, represents the number of remaining PUCCH symbols in a time slot after deducting the symbols for transmitting the demodulation reference signal (DMRS), O m represents the modulation order corresponding to different modulation schemes, and r represents the code rate (as shown in Table 1).

[0036] Table 1 Code Rate (r) Corresponding to the maxCodeRate Value

[0037] maxCodeRate Code rater 0 0.08 1 0.15 2 0.25 3 0.35 4 0.45 5 0.60 6 0.80 7 Reserved

[0038] In addition, in the related art, the base station side can also specify the PUCCH resources used by the UE side by configuring the PUCCH resource indicator parameter in the downlink control information (DCI) format for the UE side. The specific corresponding relationship is shown in Table 2.

[0039] Table 2 Mapping Relationship between PUCCH resource indicator and PUCCH resource

[0040]

[0041]

[0042] For example, when the UE schedules the new radio (NR) PUCCH format 2, the number of PUCCH RBs configured in the PUCCH resource Q m = 2, r = 0.08, and when the UCI is (O ACK + O SR + O CSI ) is from 3 to 11, the number of effective PUCCH RBs that can be calculated based on Formula 2 is shown in Table 3 below.

[0043] Table 3 Example of the number of effective RBs of PUCCH format 2

[0044]

[0045]

[0046] For another example, when the UE schedules the NR PUCCH format 3, the number of PUCCH RBs configured in the PUCCH resource O CRC = 0, Q m = 2, r = 0.08, and when the UCI is (O ACK + O SR + O CSI ) is from 3 to 11, the number of effective PUCCH RBs that can be calculated based on Formula 2 is shown in Table 4 below.

[0047] Table 4 Example of the number of effective RBs of PUCCH format 3

[0048] <![CDATA[O ACK +O SR +O CSI +O CRC > Number of valid RBs for PUCCH 3 1 4 1 5 1 6 1 7 1 8 2 9 2 10 2 11 2

[0049] Based on Table 3 and Table 4, it can be seen that when the number of UCI bits carried by the PUCCH is small, even when the minimum code rate r = 0.08 in Table 1 is used, the number of effective PUCCH RBs that can actually be scheduled by the UE side is still very small compared to the number of PUCCH RBs that can be configured in the PUCCH resource. Especially for the NR PUCCH format 3, as the number of configured PUCCH time-domain symbols increases and the number of UCI bits scheduled is small (such as the UCI bit length of 3 to 11 listed in the above example), the number of effective PUCCH RBs that can actually be scheduled by the UE side further decreases.

[0050] In the scenarios of the fifth generation mobile communication technology (5G), the future evolution of the fifth generation mobile communication technology (5G-A), and even the evolution of the sixth generation mobile communication technology (6G), there will be the following scenarios:

[0051] (1) In scenarios such as 200 megabits (Mbps, M) and 400M in the frequency domain bandwidth and high frequency and large bandwidth, the frequency domain resources are relatively abundant. When deep channel fading of individual RBs in the frequency domain is caused by multipath fading, the number of UCI bits carried by the PUCCH is small, and the number of effective PUCCH RBs actually transmitted by the UE obtained based on Formula 1 and Formula 2 under the relevant technology is small (as shown in Table 3 and Table 4), resulting in a waste of frequency domain resources and a limitation on the ability of the base station side to resist deep channel fading.

[0052] (2) In scenarios such as network controlled repeater (NCR) site switching, a large time offset will be generated. When the length of the UCI bit carried by the PUCCH is small, the number of effective PUCCH RBs actually transmitted by the UE side under the relevant technology is small, resulting in insufficient time offset estimation accuracy of the PUCCH itself on the base station side, which ultimately leads to a decrease in the PUCCH demodulation performance on the base station side.

[0053] (3) In high-speed scenarios such as high-speed rail where UEs move at high speeds, due to real-time requirements, the PUCCH on the base station side is also required to estimate and compensate for frequency offset based on its own DMRS. Similarly, when the number of UCI bits carried by the PUCCH is small, the number of effective PUCCH RBs actually transmitted by the UE side under the relevant technology is small, resulting in insufficient accuracy in the frequency offset estimation of the PUCCH itself, which in turn leads to a decrease in the PUCCH demodulation performance on the base station side.

[0054] Therefore, how to manage the number of effective RBs for transmitting UCI in PUCCH resources and improve the demodulation performance of PUCCH has become a technical problem that needs to be solved urgently.

[0055] Based on this, to solve the above technical problems, embodiments of the present disclosure provide a communication method, which is applied to the scenario of transmitting UCI via PUCCH. In the scenario where the terminal uploads UCI to the base station via PUCCH, in order to make full use of the available RBs under the PUCCH resource configuration as the effective RBs for carrying and transmitting UCI, the terminal side can correct the conventional parameters for determining the number of effective RBs according to the parameters dynamically indicated by the base station side, so that the number of effective PUCCH RBs actually transmitted by the terminal side can meet the accuracy requirements of the base station side for PUCCH time offset and frequency offset estimation and the ability to cope with deep channel fading, and improve the demodulation performance of the base station side for PUCCH.

[0056] In embodiments of the present disclosure, the network architecture of a mobile communication network (including but not limited to 2G, 3G, 4G, 5G, and future mobile communication networks (such as the evolution of future fifth-generation mobile communication technology (5th generation mobile communication technology advanced, 5G-A), sixth-generation mobile communication technology (6th generation mobile communication technology, 6G)), seventh-generation mobile communication technology (7th generation mobile communication technology, 7G))) may at least include a first communication node and a second communication node, and the first communication node and the second communication node may be abbreviated as the first node and the second node respectively.

[0057] Exemplarily, as Figure 1 shown, it is a schematic diagram of a communication system provided by embodiments of the present disclosure. The communication system may include: a first node 101 and a second node 102.

[0058] Among them, the first node 101 is used to send PUCCH to the second node 102 and carry and transmit UCI via PUCCH during the process of sending PUCCH. The second node 102 can obtain the UCI carried on the PUCCH by receiving the PUCCH sent by the first node 101.

[0059] In embodiments of the present disclosure, during the process of the first node 101 transmitting UCI via PUCCH, the number of effective RBs used for transmitting UCI in the PUCCH can be dynamically adjusted, and the second node 102 can also synchronize the dynamic adjustment of the number of effective RBs by the first node 101, so that the number of effective RBs in the PUCCH resources of the first node 101 and the second node 102 remains consistent.

[0060] In this way, the available RBs under the PUCCH resource configuration can be fully utilized as the effective RBs for carrying and transmitting UCI, so that the number of effective PUCCH RBs actually transmitted by the first node 101 can meet the accuracy requirements of the second node 102 for PUCCH time offset and frequency offset estimation and the ability to cope with deep channel fading, and improve the demodulation performance of the second node 102 for PUCCH.

[0061] It should be noted that the first node 101 may be a user equipment node, such as a passive Internet of Things device, a tag, or a terminal, etc. The second node 102 may be a network equipment node, such as a base station, an auxiliary node, or an intermediate node, etc.

[0062] Among them, a base station (BS) may be a base station in LTE, Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station device (gNB) in a 5G network, or a base station in a future communication system, etc. The base station may include various macro base stations, micro base stations, home base stations, remote radio heads, reconfigurable intelligent surfaces (RISs), routers, relay stations, transmission and reception points (TRPs), receivers, access points (APs), wireless fidelity (WIFI) devices, and other various network-side devices. Sometimes the base station may also be referred to as a reader or a transceiver for communicating with a terminal.

[0063] The terminal can be a device with wireless transceiver functions. The terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver functions, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and so on. The embodiments of the present disclosure do not limit the application scenarios. Sometimes, the terminal can also be referred to as a user, a user equipment (UE), an A-IoT device, an access terminal, a UE unit, a UE station, a mobile station, a mobile platform, a remote station, a transmitter, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent, or a UE device, etc. The embodiments of the present disclosure do not limit this.

[0064] It should be noted that Figure 1 is only an exemplary framework diagram, Figure 1 the number of devices included in it, the names of each device are not restricted, and in addition to Figure 1 the devices shown, the communication system may also include other devices, such as core network devices.

[0065] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and service scenarios described in the embodiments of the present disclosure are for more clearly explaining the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0066] Figure 2 shows a schematic flowchart of a communication method. As Figure 2 shown, this communication method is applied to a first node and includes:

[0067] S201. Receive the configuration information of the physical uplink control channel sent by the second node.

[0068] In the embodiments of the present disclosure, the configuration information of the PUCCH is used to determine the effective transmission resources for transmitting UCI in the PUCCH resources.

[0069] Among them, the effective transmission resources may include at least one of the following: RBs, subcarriers, and OFDM symbols.

[0070] It should be noted that an RB, a subcarrier, or an OFDM symbol can all be used as an effective transmission resource to transmit UCI, that is, the RBs, subcarriers, and OFDM symbols in the effective transmission resources can be replaced with each other.

[0071] In the following embodiments, the effective transmission resource is an RB (i.e., an effective RB) as an example to illustrate the embodiments of the present disclosure.

[0072] In the embodiments of the present disclosure, the configuration information of PUCCH may include the following conventional parameters shown in 1.1-1.6:

[0073] 1.1. The first number of available RBs in the PUCCH resource (i.e., the ) shown in the above formula (1);

[0074] 1.2. The second number of subcarriers used to carry UCI in each available RB of the PUCCH resource (i.e., the ) shown in the above formula (1) and formula (2);

[0075] 1.3. The third number of PUCCH symbols remaining after deducting the symbols used to transmit DMRS in one time slot (i.e., the ) shown in the above formula (1) and formula (2);

[0076] 1.4. The first code rate (i.e., r shown in the above formula (1) and formula (2));

[0077] 1.5. The modulation order (i.e., Q m ) shown in the above formula (1) and formula (2);

[0078] 1.6. The bit length of UCI (i.e., (O ACK + O SR + O CSI + O CRC )) shown in the above formula (1) and formula (2).

[0079] As a possible implementation, the first node may determine a plurality of effective RBs for transmitting UCI from the PUCCH resource according to the configuration information of the PUCCH.

[0080] In the existing related technologies, the first node may substitute the conventional parameters shown in 1.1-1.6 into the above formula (1) and formula (2) to calculate the number of effective RBs, and determine a plurality of effective RBs in the PUCCH resource in combination with the starting RB index.

[0081] It should be noted that the starting RB index can be configured by the second node for the first node through signaling. Alternatively, the starting RB index can be pre-agreed between the first node and the second node. Or, the starting RB index can be determined independently by the first node.

[0082] Among them, when the starting RB index is determined independently by the first node, the first node can send fourth indication information for indicating the starting RB index determined independently by the first node to the second node before sending UCI to the second node subsequently, so that the second node can synchronously determine multiple valid RBs for transmitting UCI in the PUCCH resource.

[0083] In some embodiments, the first code rate shown in 1.4 above is the code rate indicated by the code rate index configured by the second node in the PUCCH code rate table, and the PUCCH code rate table includes new code rate configurations extended and supplemented by the second node for the first node.

[0084] That is to say, by expanding more code rate configurations for the existing PUCCH code rate table (such as Table 1 above), the requirements for transmitting different numbers of PUCCH valid RBs can be met.

[0085] Exemplarily, for the PUCCH code rate table under the existing mechanism shown in Table 1, more maxCodeRate values and corresponding code rates r are expanded, as shown in Table 5. In Table 5, maxCodeRate = 0 to 6 are the code rate configurations described in the related art, and maxCodeRate = 7 to 9 are the newly added code rate configurations.

[0088]

[0089] S202. Send uplink control information to the second node on the effective transmission resource.

[0090] It can be understood that in the scenario where the terminal side uploads UCI to the base station side through the PUCCH, in order to make full use of the available transmission resources under the PUCCH resource configuration as the effective transmission resources for carrying and transmitting UCI, the terminal side can correct and determine the conventional parameters of the effective transmission resources according to the parameters dynamically indicated by the base station side, so that the actually transmitted PUCCH effective transmission resources on the terminal side can meet the accuracy requirements of the base station side for PUCCH time offset and frequency offset estimation and the ability to cope with deep channel fading, and improve the demodulation performance of the base station side for the PUCCH.

[0091] In some embodiments, the configuration information of the PUCCH may further include at least one of the dynamic parameters shown in 2.1-2.3 below:

[0092] 2.1. The number parameter of the effective transmission resources (such as effective RBs) configured by the second node;

[0093] 2.2. The configuration condition of the number of effective transmission resources (such as effective RBs);

[0094] 2.3. The usage mode of the effective transmission resources (such as effective RBs);

[0095] It should be noted that the configuration information of the PUCCH including the conventional parameters shown in 1.1-1.6 above and the dynamic parameters shown in any one of 2.1-2.3 can be configured by the second node through radio resource control (RRC) signaling, or by the second node through downlink control information (DCI), or by the second node through a medium access control control element (MAC CE).

[0096] In some embodiments, for the dynamic parameter shown in 2.1 above, the number parameter of the effective RBs may be a new RRC parameter in the RRC signaling sent by the second node to the first node, and is used to determine the number of effective RBs for transmitting UCI.

[0097] The following takes the new RRC parameter in the RRC signaling to indicate the number of effective RBs of the PUCCH as an example for illustration.

[0098] When the configuration information of the PUCCH includes the number parameter of the effective RBs configured by the second node, in the process that the first node determines multiple effective resource blocks for transmitting the uplink control information from the physical uplink control channel resources according to the configuration information of the physical uplink control channel, the first node may use the first number indicated by the number parameter of the effective RBs as the multiple effective RBs for the available RBs in the PUCCH resources.

[0099] That is to say, when the configuration information of the PUCCH includes the number parameter of the effective transmission resources and the number parameter of the effective transmission resources is the first number, the effective transmission resources may include the first number of available transmission resources in the PUCCH resources.

[0100] Exemplarily, if the quantity parameter of the valid RBs is 2, the first node may determine that the first quantity of the valid RBs is 2. If all available RBs in the PUCCH resource include: RB1, RB2, and RB3, the first node may use both RB2 and RB3 as valid RBs.

[0101] Among them, in the process that the first node uses the first quantity of available RBs in the PUCCH resource as multiple valid RBs according to the first quantity indicated by the quantity parameter of the valid RBs, the first node may compare the first quantity with the quantity of all available RBs, and when the first quantity is less than or equal to the quantity of all available RBs, use the first quantity of available RBs in the PUCCH resource as multiple valid RBs.

[0102] In addition, when the first quantity indicated by the quantity parameter of the valid RBs is greater than the quantity of all available RBs in the PUCCH resource, the first node may use all available RBs in the PUCCH resource as multiple valid RBs.

[0103] That is to say, when the first quantity is greater than the quantity of available transmission resources in the PUCCH resource, the valid transmission resources may include all available transmission resources in the PUCCH resource.

[0104] Thus, taking the RRC signaling as an example, when a corresponding new parameter is configured in the RRC signaling and the UE side determines the number of valid PUCCH RBs for actual transmission, it no longer uses the related technical methods described by the above formula 1 and formula 2, but directly determines the number of valid PUCCH RBs according to this parameter. When the value of this parameter exceeds the number of PUCCH RBs that the corresponding UE can actually schedule, the UE follows all the PUCCH RBs that it can actually schedule for transmission.

[0105] It should be noted that in the embodiments of the present disclosure, the quantity parameter of the valid transmission resources (such as valid RBs) may be a quantity parameter at the uplink bandwidth part (UL BWP) level. Or, the quantity parameter of the valid transmission resources (such as valid RBs) may be a quantity parameter at the PUCCH priority level. Or, the quantity parameter of the valid transmission resources (such as valid RBs) may be a quantity parameter at the cell level. Or, the quantity parameter of the valid transmission resources (such as valid RBs) may be a quantity parameter at the PUCCH resource level. Or, the quantity parameter of the valid transmission resources (such as valid RBs) may be a quantity parameter at the PUCCH format level.

[0106] Exemplarily, taking the number parameter of valid RBs at the UL BWP level as an example, for each UL BWP, an RRC parameter is newly added to indicate the number of valid RBs of PUCCH. This parameter can be the specific number of RBs, or it can be an index for obtaining the specific number of RBs based on a table.

[0107] Alternatively, taking the number parameter of valid RBs at the PUCCH priority level as an example, the number of valid RBs of PUCCH can be configured or not configured separately for different priorities of PUCCH. For example, a PUCCH priority index set {0, 1} can be configured to configure different priorities of the number of valid RBs. For the PUCCH priority index 0, a PUCCH valid RB number parameter (denoted as configuration parameter 0) is configured, and for all UEs subordinate to the PUCCH priority index 0, the number of valid RBs of PUCCH is determined according to configuration parameter 0; for the PUCCH priority index 1, another PUCCH valid RB number parameter (denoted as configuration parameter 1) can be configured or not configured, and for all UEs subordinate to the PUCCH priority index 1, the number of valid RBs of PUCCH is determined according to configuration parameter 1. If no PUCCH valid RB number parameter is configured for the PUCCH priority index 1, the number of valid RBs of PUCCH transmitted on the UE side is determined according to the related technology (i.e., the above formula 1 and formula 2).

[0108] Or, taking the number parameter of valid RBs at the cell level as an example, when this parameter is configured at the cell level, it takes effect for all UEs under this cell. For example, when configuring the PUCCH valid RB number parameter at the cell level, when the number of PUCCH RBs indicated by this parameter is greater than or equal to the number of PUCCH RBs configured in the corresponding PUCCH resource, the transmission is directly carried out according to the number of RBs in this PUCCH resource; when the number of PUCCH RBs indicated by this parameter is less than the number of PUCCH RBs configured in the corresponding PUCCH resource, the transmission is directly carried out according to the number of PUCCH RBs indicated by this parameter.

[0109] Or, taking the number parameter of valid RBs at the PUCCH resource level as an example, for each PUCCH resource within the BWP, a PUCCH valid RB number parameter is configured. When the UE configures the corresponding PUCCH resource, the number of valid RBs of PUCCH transmitted on the UE side is determined according to the indication of this parameter.

[0110] As another possible implementation, the number parameter of valid RBs can be a newly added parameter in the DCI sent by the second node to the first node, which is used to determine the number of valid RBs for transmitting UCI.

[0111] That is to say, by dynamically indicating the number of valid PUCCH RBs transmitted on the UE side through the newly added parameters of DCI, the related technical methods described in Formula 1 and Formula 2 above can no longer be used to determine the number of valid PUCCH RBs.

[0112] In addition, when the value of this parameter exceeds the number of PUCCH RBs that the corresponding UE can actually schedule, the UE transmits all the PUCCH RBs that it can actually schedule.

[0113] It should be noted that the method of newly introducing parameters in DCI may specifically include:

[0114] (1) The number of valid PUCCH RBs can be indicated by adding new parameters to the PUCCH resource indicator in DCI format. In the related technology, as shown in Table 2, the maximum length of the PUCCH resource indicator is 3 bits. For example, by expanding the bit length of the PUCCH resource indicator, the newly expanded bit positions can be used to represent the number of valid PUCCH RBs of the corresponding PUCCH resource. Assuming that the maximum number of valid PUCCH RBs to be indicated is 16, 4 additional bits can be added to the PUCCH resource indicator to indicate the number of valid PUCCH RBs, as shown in Table 6.

[0115] Table 6 The number of valid PUCCH RBs corresponding to the newly expanded 4 bits

[0116]

[0117]

[0118] (2) A new DCI format can also be added, which includes parameters for indicating the number of valid PUCCH RBs.

[0119] Taking the example of dynamically indicating the number of valid PUCCH RBs transmitted on the UE side by adding extended bit parameters to DCI, the following description is provided.

[0120] The number of valid RBs configured by the second node can be the resource indicator of the PUCCH. When the configuration information of the PUCCH includes the parameter of the number of valid RBs configured by the second node, in the process that the first node determines multiple valid resource blocks for transmitting uplink control information from the physical uplink control channel resources according to the configuration information of the physical uplink control channel, the first node can determine the first number corresponding to the resource indicator of the PUCCH in the preset resource mapping table, and use all the available RBs with the first number in the PUCCH resources as multiple valid RBs to determine multiple valid RBs.

[0121] Among them, the preset resource mapping table can include preset indicators with different bit lengths. One preset indicator corresponds to a candidate number of valid RBs, and the bit length is associated with the largest candidate number in the preset resource mapping table (refer to the mapping table shown in Table 4 corresponding to 16 valid RBs above).

[0122] Optionally, the preset resource mapping table can include preset indicators with different bit lengths, and the bit length can be a positive integer greater than or equal to 1.

[0123] That is to say, the preset resource mapping table can be a combination of Table 2 and Table 6 above, including resource indicators with different bit lengths of 1, 2, 3, and 4.

[0124] In the embodiments of the present disclosure, when the configuration information of the PUCCH includes the parameter of the number of valid RBs configured by the second node, in the process that the first node determines multiple valid resource blocks for transmitting uplink control information from the physical uplink control channel resources according to the configuration information of the physical uplink control channel, the first node can first determine whether the parameter of the number of valid RBs is a valid value (such as whether it is a positive integer, or in the sequence format shown in Table 6). If the parameter of the number of valid RBs is a valid value, the first node can use the first number corresponding to the parameter of the number of valid RBs (such as the directly indicated first number above, or the first number indicated based on the resource indicator in the preset resource mapping table) to use all the available RBs with the first number in the PUCCH resources as multiple valid RBs.

[0125] Alternatively, when the parameter of the number of valid RBs is an invalid value, the first node can determine the first number of valid RBs according to the above first code rate, second number, third number, modulation order, and bit length of UCI. Then, the first node can use all the available RBs with the first number in the PUCCH resources as multiple valid RBs.

[0126] In some embodiments, the number configuration conditions of the effective transmission resources (such as effective RBs) shown in 2.2 above can include at least one of the following 3.1 - 3.3:

[0127] 3.1. When the bandwidth of the uplink bandwidth part of the first node is greater than a preset bandwidth threshold (or greater than a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit), all available transmission resources in the PUCCH resource are used as effective transmission resources (such as effective RBs).

[0128] That is to say, the configuration condition can be that the UL BWP bandwidth is greater than a predefined minimum bandwidth threshold, or the UL BWP bandwidth is less than or equal to a predefined maximum bandwidth threshold, and all available RBs corresponding to the PUCCH resource configuration are directly transmitted.

[0129] For example, when the activated UL BWP bandwidth on the UE side is greater than the predefined bandwidth threshold, all UEs under this UL BWP transmit all available RBs corresponding to the PUCCH resource configuration.

[0130] 3.2. When the frequency or frequency band of the first node is within a preset frequency domain resource range, all available transmission resources in the PUCCH resource are used as effective transmission resources (such as effective RBs).

[0131] That is to say, the configuration condition can be based on RRC parameters related to frequency or frequency band. When the frequency or frequency band configured on the UE side meets the predefined frequency or frequency band range, all available RBs corresponding to the PUCCH resource configuration are directly transmitted.

[0132] For example, the corresponding frequency can be obtained through the absolute radio frequency channel number (ARFCN) parameter in the RRC parameters and the frequency band table. When the frequency configured on the UE side is within the predefined frequency range, all available RBs corresponding to the PUCCH resource configuration are directly transmitted.

[0133] 3.3. When the service parameters of the first node are in a preset parameter set, all available transmission resources in the PUCCH resource are used as effective transmission resources (such as effective RBs).

[0134] That is to say, the configuration condition can be based on RRC parameters related to the service scenario. When the RRC parameters of the corresponding service scenario configured on the UE side are enabled or the parameter values meet the preset parameter range, all available RBs corresponding to the PUCCH resource configuration are directly transmitted.

[0135] For example, when the timing advance report (ta-Report) parameter in the non-terrestrial networks (NTN) parameters is configured to enabled, all available RBs under the corresponding PUCCH resource configuration are directly transmitted. Another example is that when the highSpeedMeasFlag in the HighSpeedConfig parameter is configured to true, all available RBs under the corresponding PUCCH resource configuration are directly transmitted.

[0136] Optionally, when the configuration information includes both the quantity parameter of the effective transmission resources (such as effective RBs) shown in 2.1 above and the quantity configuration conditions shown in 2.2, the quantity configuration conditions further include at least one of the following 3.4 - 3.6:

[0137] 3.4. When the bandwidth of the uplink bandwidth part of the first node is greater than a preset bandwidth threshold (or greater than a preset lower bandwidth value and less than or equal to a preset upper bandwidth value), according to the first quantity indicated by the quantity parameter of the effective RBs, the first quantity of available transmission resources in the PUCCH resources is used as the effective transmission resources (such as effective RBs);

[0138] That is to say, the configuration condition can be that the UL BWP bandwidth is greater than a predefined minimum bandwidth threshold, or the UL BWP bandwidth is less than or equal to a predefined maximum bandwidth threshold, and the number of PUCCH effective RBs indicated by the RRC parameter under the corresponding PUCCH resource configuration is directly transmitted.

[0139] 3.5. When the frequency or frequency band of the first node is within a preset frequency domain resource range, according to the first quantity indicated by the quantity parameter of the effective RBs, the first quantity of available transmission resources in the PUCCH resources is used as the effective transmission resources (such as effective RBs);

[0140] That is to say, the configuration condition can be based on RRC parameters related to frequency or frequency band. When the frequency or frequency band configured on the UE side meets the predefined frequency or frequency band range, the number of PUCCH effective RBs indicated by the RRC parameter under the corresponding PUCCH resource configuration is directly transmitted.

[0141] 3.6. When the service parameter of the first node exists in a preset parameter set, according to the first quantity indicated by the quantity parameter of the effective RBs, the first quantity of available transmission resources in the PUCCH resources is used as the effective transmission resources (such as effective RBs).

[0142] That is to say, the configuration condition can be based on RRC parameters related to the service scenario. When the RRC parameters corresponding to the service scenario configured on the UE side enable or the parameter values satisfy the preset parameter range, directly transmit the number of valid PUCCH RBs indicated by the RRC parameters under the corresponding PUCCH resource configuration.

[0143] It can be understood that when the first node meets the predefined RRC configuration condition, directly transmit all available RBs under the corresponding PUCCH resource configuration or the number of valid PUCCH RBs indicated by the RRC parameters. When the predefined RRC configuration condition takes effect, the UE side no longer uses the related technical methods described in Formula 1 and Formula 2 above to determine the number of valid PUCCH RBs, but can perform PUCCH transmission by occupying all available RBs under the corresponding PUCCH resource configuration, or transmit according to the number of valid PUCCH RBs indicated by the above RRC parameters. When the predefined condition is not met, the UE side then determines the number of PUCCH RBs to be transmitted according to the related technology (i.e., Formula 1 and Formula 2 above).

[0144] In the embodiments of the present disclosure, if the first node autonomously determines the number of valid RBs based on the quantity configuration condition, before the first node sends UCI to the second node, the first node can send first indication information for indicating the satisfaction of the quantity configuration condition by the first node to the second node, so that the second node can determine the number of valid RBs corresponding to the subsequent UCI to be received according to the satisfaction of the quantity configuration condition by the first node.

[0145] Optionally, in the case where the configuration information of the PUCCH includes the quantity configuration condition of the valid RBs, in the process that the first node determines multiple valid resource blocks for transmitting the uplink control information from the physical uplink control channel resources according to the configuration information of the physical uplink control channel, the first node can first determine whether the first node meets this quantity configuration condition. If the first node meets the quantity configuration condition, the first node can determine multiple valid RBs according to the methods shown in 3.1 - 3.6 above.

[0146] Or, in the case where the first node does not meet the quantity configuration condition, the first node can determine the first quantity of valid RBs according to the above first code rate, second quantity, third quantity, modulation order, and bit length of the UCI. Then, the first node can use the first quantity of available RBs in the PUCCH resource as multiple valid RBs.

[0147] In some embodiments, the usage manner of the above-mentioned valid transmission resources (such as valid RBs) shown in 2.3 may include at least one of the following:

[0148] Use all available transmission resources in the PUCCH resource as valid transmission resources (such as valid RBs);

[0149] Determine valid transmission resources (such as valid RBs) in the PUCCH resource based on predefined rules.

[0150] As a possible implementation, the configuration information of the PUCCH may include a fifth indication information, and the fifth indication information is used to indicate the usage mode of the valid transmission resources.

[0151] Exemplarily, taking the valid transmission resource as a valid RB as an example, the fifth indication information may be the number parameter of the valid RB, and the number parameter of the valid RB may be 1 bit. The two values of this 1 bit respectively correspond to two ways of determining the valid transmission resources:

[0152] Method 1: All transmission resources in the PUCCH are used as valid transmission resources;

[0153] Method 2: Determine the valid transmission resources in the PUCCH based on predefined rules.

[0154] Among them, the transmission of this 1-bit information is based on the RRC message, DCI in the PDCCH or MAC CE.

[0155] The base station (i.e., the second node) sends this 1-bit information to the UE (i.e., the first node). And the base station determines the valid transmission resources for receiving the UCI from the PUCCH resource based on the set value of this 1 bit, and receives the UCI from the valid transmission resources.

[0156] The UE receives this 1-bit information from the base station, and determines the valid transmission resources for transmitting the UCI in the PUCCH resource based on the value of this 1 bit, and sends the UCI in the determined valid transmission resources.

[0157] It should be noted that the fifth indication information may be a parameter of the Boolean type. For example, when the parameter value is true, directly schedule all the PUCCH RBs that can be scheduled under the corresponding PUCCH resource. When the parameter value is false, determine the number of valid PUCCH RBs transmitted by the UE according to the related technologies (i.e., the above formula one and formula two).

[0158] It can also be judged whether to schedule all the PUCCH RBs according to whether the parameter value is 0 or whether the parameter is configured. For example, when the parameter value is 0 or not configured, determine the number of valid PUCCH RBs transmitted by the UE according to the related technologies (i.e., the above formula one and formula two). When the parameter is a non-zero value, directly schedule all the PUCCH RBs that can be scheduled under the corresponding PUCCH resource.

[0159] Exemplarily, the predefined condition in Mode 2 may also be at least one of the configuration conditions described in 3.1-3.6.

[0160] In some embodiments, the effective transmission resource is determined according to the configuration information of the PUCCH and the code rate scaling factor of the effective transmission resource. The code rate scaling factor is used to scale the first code rate in the conventional parameters, so as to update and modify on the basis of the initial code rate for determining the number of effective RBs, so as to meet the demodulation requirements of the second node for the PUCCH.

[0161] That is to say, compared with the initial code rate used for transmission of the existing UCI in the PUCCH resource, as shown in Table 1, the embodiments of the present disclosure provide a more efficient code rate for the transmission of the UCI in the PUCCH resource by magnifying or reducing on the basis of the initial code rate, so that the number of effective RBs of the PUCCH can be configured more flexibly.

[0162] As a possible implementation manner, when the configuration information of the PUCCH includes the code rate scaling factor of the effective RB, in the process that the first node determines a plurality of effective resource blocks for transmitting the uplink control information from the physical uplink control channel resources according to the configuration information of the physical uplink control channel, the first node may magnify or reduce the first code rate according to the code rate scaling factor to obtain a second code rate. Then, the first node may determine the first number of effective RBs according to the second code rate, the second quantity, the third quantity, the modulation order, and the bit length of the UCI. Then, the first node may use the first number of available RBs in the PUCCH resource as the plurality of effective RBs.

[0163] That is to say, the effective transmission resource may include the first number of available transmission resources determined by the second code rate, the second quantity, the third quantity, the modulation order, and the bit length in the PUCCH resource, and the second code rate is the first code rate after being magnified or reduced as indicated by the code rate scaling factor.

[0164] In this way, by multiplying the code rate scaling factor by the first code rate r obtained under the existing mechanism, the final code rate r' is obtained. The first code rate r obtained under the existing mechanism may be obtained through the PUCCH code rate table shown in Table 1 above, or through the configured PUSCH code rate table.

[0165] In this way, after the UE side obtains the code rate scaling factor, the final code rate r' is obtained in the above manner, and then the number of effective RBs of the PUCCH actually transmitted by the UE side is obtained according to the related technologies shown in Formula 1 and Formula 2 above.

[0166] Exemplarily, assuming that based on the currently configured PUSCH code rate table, the first code rate that can be obtained If the code rate scaling factor is set to 1, the final updated code rate Based on the configuration conditions given in the examples of Table 3 and Table 4 above, combined with the final code rate r′, the number of valid RBs of PUCCH obtained respectively can be shown in Table 7 and Table 8 below.

[0168] <![CDATA[O ACK +O SR +O CSI +O CRC > Number of valid RBs for PUCCH 3 4 4 5 5 6 6 7 7 8 8 9 9 10 10 11 11 12

[0171] It should be noted that in the embodiments of the present disclosure, the code rate scaling factor may be configured by the second node for the first node. Alternatively, the code rate scaling factor may be pre-configured in the first node.

[0172] Among them, the code rate scaling factor may be configured by RRC, and the code rate scaling factor may be at the channel level, ULBWP level, or different priority levels.

[0173] Alternatively, the code rate scaling factor may be dynamically configured and sent through DCI. In this way, after the UE obtains a code rate according to the existing mechanism, the final code rate is determined together with the code rate scaling factor notified by DCI.

[0174] Alternatively, the code rate scaling factor may be dynamically configured and sent through MAC CE. In this way, after the UE obtains a code rate according to the existing mechanism, the final code rate is determined together with the code rate scaling factor notified by MAC CE.

[0175] In addition, the code rate scaling factor pre-configured in the first node may be pre-configured by the first node and the second node in advance. Alternatively, the code rate scaling factor pre-configured in the first node may be determined independently by the first node.

[0176] In the embodiments of the present disclosure, when the code rate scaling factor is pre-configured in the first node, before the first node sends UCI to the second node, the first node may send second indication information for indicating the code rate scaling factor pre-configured in the first node to the second node, so that the second node can determine the number of valid RBs corresponding to the UCI to be received subsequently according to the code rate scaling factor pre-configured in the first node.

[0177] It should be noted that the value of the code rate scaling factor may be a positive integer greater than or equal to 1, or a floating point number greater than 0 and less than 1.

[0178] As another possible implementation, when the configuration information of the PUCCH includes the code rate scaling factor of the valid RBs, in the process that the first node determines multiple valid resource blocks for transmitting uplink control information from the physical uplink control channel resources according to the configuration information of the physical uplink control channel, the first node may first determine whether the code rate scaling factor is a valid value (i.e., whether it meets the above-mentioned value range). If the code rate scaling factor is a valid value, the first node may amplify or reduce the first code rate according to the code rate scaling factor to obtain a second code rate. After that, the first node may use the first number of available RBs in the PUCCH resources as the multiple valid RBs.

[0179] Alternatively, when the code rate scaling factor is an invalid value, the first node may determine the first number of valid RBs according to the above-mentioned first code rate, second number, third number, modulation order, and bit length of the UCI. After that, the first node may use the first number of available RBs in the PUCCH resources as the multiple valid RBs.

[0180] That is to say, when the configured code rate scaling factor is a valid value within the above-mentioned value range, it can be used to calculate the final code rate r'. When the code rate scaling factor is not configured or the configured code rate scaling factor is an invalid value, the first code rate obtained according to the existing mechanism is used and the relevant technologies (i.e., the above-mentioned formula 1 and formula 2) are followed to obtain the number of PUCCH valid RBs.

[0181] In some embodiments, the effective transmission resources are determined according to the configuration information of the PUCCH and the sequence extension parameter of the UCI. Among them, the sequence extension parameter of the UCI is used to perform extension processing on the bit sequence of the UCI to amplify the bit length of the UCI in the conventional parameters, so as to perform update and modification on the basis of the initial bit length for determining the number of valid RBs, so as to meet the demodulation requirements of the second node for the PUCCH.

[0182] Among them, the sequence extension parameter may be configured by RRC, or may be configured by DCI or MAC CE.

[0183] That is to say, by extending the sequence bit length of the UCI information carried on the PUCCH, and then based on the existing code rate and mechanism, the number of PUCCH valid RBs transmitted by the UE side can be increased. In this way, when the sequence carrying the UCI is extended, the UE side generates and transmits signals according to the extended sequence, and follows the existing code rate and mechanism to determine the number of PUCCH valid RBs transmitted by the UE side.

[0184] As a possible implementation manner, when the configuration information of the PUCCH includes the sequence extension parameter of the UCI, in the process that the first node determines multiple valid resource blocks for transmitting the uplink control information from the physical uplink control channel resources according to the configuration information of the physical uplink control channel, the first node may perform length extension processing on the UCI according to the sequence extension parameter to obtain the extended UCI. Then, the first node may determine the first number of valid RBs according to the above first code rate, second quantity, third quantity, modulation order, and the bit length of the extended UCI. After that, the first node may use the first number of available RBs in the PUCCH resources as the multiple valid RBs.

[0185] That is to say, the effective transmission resources may include the first number of available transmission resources in the PUCCH resources determined by the first code rate, second quantity, third quantity, modulation order, and the extended bit length, and the extended bit length is the bit length of the UCI after the extension processing indicated by the sequence extension parameter.

[0186] It should be noted that the sequence extension parameter may be the repetition times N of the whole UCI, and N is a positive integer greater than 1. That is, the extension processing indicated by the sequence extension parameter is to repeat and splice the whole UCI N times. In the process that the first node performs length extension processing on the UCI according to the sequence extension parameter to obtain the extended UCI, the first node may repeat and splice the whole UCI N times to obtain the extended UCI, and the bit length of the extended UCI is N times the bit length of the UCI.

[0187] Exemplarily, if the UCI is a 6-bit sequence 010101 and the repetition times of the whole UCI indicated by the sequence extension parameter is 2, then the extended UCI is a 12-bit sequence 010101010101.

[0188] Alternatively, the sequence extension parameter may be the repetition times N of each character in the UCI, and N is a positive integer greater than 1. That is, the extension processing indicated by the sequence extension parameter is to insert N - 1 characters identical to the character after each character in the UCI. In the process that the first node performs length extension processing on the UCI according to the sequence extension parameter to obtain the extended UCI, for each character in the UCI, the first node may insert N - 1 characters identical to this character after the character to obtain the extended UCI, and the bit length of the extended UCI is N times the bit length of the UCI.

[0189] Exemplarily, if the UCI is a 6-bit sequence 010101 and the repetition times of each character in the UCI indicated by the sequence extension parameter is 2, then the extended UCI is a 12-bit sequence 001100110011.

[0190] That is to say, the bit length of the sequence carrying the UCI information sequence can be extended by N times through sequence repetition. Specifically, for the sequence repetition method, all bits of the sequence carrying the UCI information can be repeatedly copied N times as a whole, and finally a sequence with a length N times that of the original sequence length is obtained. Each bit of the sequence carrying the UCI information can also be repeatedly copied N times respectively, and finally a sequence with a length N times that of the original sequence length can also be obtained.

[0191] Therefore, according to the sequence repetition method and based on the existing mechanism, for different repetition multiples, the number of valid PUCCH RBs corresponding to the set conditions in Table 3 and Table 4 above can be increased to the number of valid PUCCH RBs corresponding to Table 9 and Table 10 respectively.

[0192] Table 9 Example of the number of valid PUCCH format2 RBs corresponding to different sequence repetition multiples

[0193]

[0194]

[0195] Table 10 Example of the number of valid PUCCH format3 RBs corresponding to different sequence repetition multiples

[0196]

[0197] Alternatively, the sequence extension parameter can be the extended length of the CRC in the UCI. The extension process indicated by the sequence extension parameter is to perform length extension processing on the CRC in the UCI according to the extended length. In the process that the first node performs length extension processing on the UCI according to the sequence extension parameter to obtain the extended UCI, the first node can perform length extension processing on the CRC in the UCI according to the extended length to obtain the extended UCI, and the CRC length in the extended UCI is the extended length.

[0198] That is to say, when the UCI sequence contains a CRC, the length of the UCI sequence can also be extended by increasing the length of the CRC in the UCI sequence.

[0199] Therefore, in the process that the first node sends the uplink control information to the second node on the effective transmission resource, the first node can send the extended UCI to the second node on the effective transmission resource.

[0200] It should be noted that the sequence extension parameter can be configured by the second node for the first node through signaling. Or, the sequence extension parameter can be pre-agreed by the first node and the second node. Alternatively, the starting RB index can be determined independently by the first node.

[0201] It should be noted that, in the embodiments of the present disclosure, the sequence extension parameter may be configured by the second node for the first node. Alternatively, the sequence extension parameter may be pre-configured in the first node.

[0202] Among them, the sequence extension parameter pre-configured in the first node may be pre-configured by the first node and the second node in advance. Alternatively, the sequence extension parameter pre-configured in the first node may be determined independently by the first node.

[0203] In the embodiments of the present disclosure, when the sequence extension parameter is pre-configured in the first node, before the first node sends UCI to the second node, it may send third indication information for indicating the sequence extension parameter pre-configured in the first node to the second node, so that the second node can determine the number of valid RBs corresponding to the UCI to be received subsequently according to the sequence extension parameter pre-configured in the first node.

[0204] In some embodiments, the effective transmission resource is jointly determined by the configuration information of the PUCCH, the code rate scaling factor of the effective transmission resource, and the sequence extension parameter.

[0205] The embodiments of the present disclosure further provide a communication method, which is applied to the second node, as Figure 3 shown, this communication method may include:

[0206] S301. Send the configuration information of the physical uplink control channel to the first node.

[0208] S302. Receive the uplink control information sent by the first node on the effective transmission resource.

[0209] Among them, the effective transmission resource is determined according to the configuration information of the PUCCH.

[0210] It should be noted that for the introduction of determining the effective transmission resource according to the configuration information of the PUCCH, reference may be made to the description of the above embodiments, which will not be elaborated here.
